Preface
This research enquiry into demand management began as a project that linked the water,
transport and energy themes of the Monash Sustainability Institute (MSI). MSI was invited to
submit a working paper on demand management to the Australian Davos Connection
Infrastructure 21 Summit, held in October 2008. The paper advocated a whole-of-system
approach to managing demand in water, transport and electricity sectors, and proposed a set
of demand management principles that drew on experience from the three sectors. Our main
realisation was that the electricity sector has not yet made significant progress with demand
management or efficiency, compared to the water and transport sectors, and would benefit
greatly from development of a comprehensive strategy to reduce electricity consumption.
This project received funding from the Helen Macpherson Smith Trust (under the title
―Improving the efficiency of electricity and water use in Victoria‖) in order to: 1) review best-
practice demand management and efficiency measures in the electricity sector both in
Australia and Internationally; 2) evaluate the ‗situation‘ in Victoria relating to electricity
regulation, policy and industry structure; 3) to develop a program of electricity demand
management measures for Victoria; and 4) to facilitate the uptake of this program.
The scope of this project was originally to consider ‗improving the efficiency of electricity and
water use in Victoria‘. Through our research we found that Victoria‘s urban and rural water
sectors have become significantly more efficient over the past decade, and are on a
trajectory to achieve even greater efficiency gains, simply because there have been strong
incentives to save water. The factors driving this have included on-going drought, increasing
population, an increase in water allocated to the environment and the threat of further
reduced water availability due to climate change. The challenges facing Melbourne‘s water
supply situation are detailed in a 2009 report published by the Monash Sustainability
Institute, which includes recommendations for dealing with the water crisis through
strengthened demand management and water efficiency programs (Wallis et al., 2009).
Thus, for this report, we did not consider measures that can improve the efficiency of water
use in Victoria, as we believe that there are strong drivers of efficiency already in place;
namely a lack of water. In contrast, there is no lack of inexpensive brown coal to generate
electricity in Victoria, explaining why there have been no serious attempts to reduce
electricity demand in this State.
In the context of human-induced climate change, a desirable transformation of Victoria‘s
electricity system would involve a transition from the current carbon-intensive and high-
demand electricity regime to one characterised by low carbon intensity and low electricity
demand. Strategies to achieve this goal include:
replacement of fossil fuel-based power generation with renewable energy;
reduction of wasted energy through energy efficiency; and
improvement of end-use energy efficiency through demand management.
The purpose of this study, therefore, was to identify measures to reduce electricity
consumption through demand management and energy efficiency in order to facilitate this
transition to a post-carbon society in Victoria.

PART A. INTRODUCTION AND RECOMMENDATIONS
A.1. Summary
Australia faces a grand challenge to reduce its emissions of greenhouse gases. Electricity
generation is Australia‘s single largest source of greenhouse gas emissions, increasing
nearly twelve-fold since 1961, and both supply and demand elements of energy must be
addressed in the transition to a low-carbon society. The growth in energy use has also led to
an increase in peak electricity demand on hot days, and in Victoria critical peak demand1
accounts for 0.3 percent of electricity supply by time (about 25 hours annually on average
since 2001), but is responsible for nearly 18 percent of the annual wholesale cost of
electricity. A massive growth in expenditure on the electricity distribution network is also
projected, directly as a result of increasing peak demand.
Reducing the carbon intensity of electricity supply, cutting unnecessary waste of electricity
and improving end-use energy efficiency are key to Victoria‘s and Australia‘s response to
reducing greenhouse gas emissions. Reducing the carbon intensity of the electricity industry
in Victoria necessitates a shift from fossil fuels to renewable energy. Improving the energy
efficiency of appliances and buildings and thereby reducing energy waste can be achieved,
without changing behaviour, by following the measures outlined in the ClimateWorks
Australia Low Carbon Growth Plan (ClimateWorks Australia, 2010). Increasing end-use
energy efficiency, so as to reduce the energy needed to perform specific tasks, requires
changes in behaviour facilitated by a range of demand management strategies.
1 Here, critical peak demand refers to the highest spot-price class of electricity (>$300 per megawatt).
Page 2
This report presents a review of electricity demand management measures that have been
implemented internationally and assesses how these measures could be implemented in the
Victorian context, with recommendations for systemic change to reduce energy use.
In summary, it is recommended that the State of Victoria, as part of the National Electricity
Market, implement electricity pricing for households and business consumers that better
reflects the time-dependent costs of providing electricity. This can be implemented in
conjunction with the use of smart meters in order to provide consumers with feedback on the
costs and impacts of their electricity use. These measures, if applied properly and equitably,
can be used to achieve reductions in peak electricity demand and reductions in overall
demand for electricity.
Price signals, however, are not sufficient measures by themselves to reduce energy use and
greenhouse gas emissions, so it is also recommended that a comprehensive behaviour
change strategy for electricity use is established, in conjunction with the provision of an
enabling framework for consumers to reduce electricity use. In Victoria, this framework could
take the form of an enhanced and strengthened energy efficiency certificates scheme2, in
addition to the feedback provided by smart meters. These measures would foster
‗responsible‘ energy-using behaviour among consumers, as well as meeting the conditions
for ‗response-ability‘ by arming them with the means and information needed to actually
reduce their electricity use.
It is also recommended that incentives should be provided to the electricity distribution
industry to pursue efficiency and demand management, in order to shift the focus away from
earnings based on electricity sales, to earnings based on efficiency. It is crucial that the
electricity industry is motivated to reduce electricity demand and is rewarded for doing so.
Finally, we recommend embedding the goal of transitioning to a ‗post-carbon society‘ in the
strategic focus of the National Electricity Market. These measures would support a regime-
change to an electricity system that rewards energy efficiency and help to overcome some of
the barriers to change.

A.2. Recommendations and targets
Recommendation Actions to be taken Relevant parties
1. Pricing/Smart meters. Implement electricity pricing that captures time-dependent costs using smart meters for households and small business. Time-variable price signals, and the smart meters that enable them, provide consumers with an incentive to shift demand from peak periods and also enable consumers to get feedback on their consumption, which is important in reducing energy use.
Rollout smart meters and compensate low-income households for costs
Introduce time-dependent
pricing and give low-income
households ‗opt-in‘ ability
Provide the means for direct/indirect feedback on consumption.
Victorian Government
Electricity retailers
Individuals and households
Small and medium businesses
2. Behaviour change. Build on the planned behaviour change strategy for electricity use in the Victorian Climate Change White Paper. Electricity has been treated as an infinite resource, as evidenced by the massive growth in per capita use over the last fifty years. A strategy that encourages responsible behaviour by the community would provide a signal that electricity demand is too high.
Implement a comprehensive behaviour change strategy to reduce energy consumption in Victoria that involves persuasion campaigns backed up by participatory decision-making and community programs.
Victorian Government
Sustainability Victoria
Community NGOs
Environment Victoria
3. Efficiency Provide an enabling framework for consumers to reduce electricity use. In addition to efforts to promote ‗responsible‘ behaviour, efforts need to be made to ensure the circumstances for ‗response-ability‘ are also created; that is, a framework that enables the community to translate their intentions into actions.
We recommend strengthening and expanding the Victorian Energy Saver Incentive scheme, making it more accessible and broad-ranging, to support consumer behaviour change.
Essential Services Commission
Appliance Retailers (Harvey Norman, Bunnings, etc.)
4. DM Incentives To effectively reduce electricity use in Victoria, the industries involved in electricity distribution and retail need to be provided with strong incentives to implement demand management programs.
Provide the energy industry with incentives for undertaking Demand Management and address current barriers to action. Regulatory incentives that have been implemented internationally provide guidance.
Australian Energy Regulator
Australian Electricity Market Commission
Energy industry
5. Sustainability Embed environmental concerns in the strategic focus of the regulators. The priorities of the agencies that regulate and manage the National Electricity Market are almost solely focused on price, quality, safety, security and reliability of supply. Consumer advocacy issues are addressed in a limited way, and environmental issues are not considered at all.
We recommend embedding the goals of environmental protection and the transition to a low carbon society as priorities of the National Electricity Market in order to facilitate a transition to a more sustainable electricity supply regime.

A.3. Introduction
There is international consensus on the need to reduce human-induced greenhouse gas
emissions in order to stabilise and decrease the amount of these gases in the atmosphere,
so as to prevent or ameliorate adverse climate change (CSIRO, 2007, IPCC, 2007). The
transition to a ‗post-carbon society‘ requires a concerted global effort to respond to climate
change, within which mitigation strategies will play a key role, in order to simultaneously
reduce the likelihood of adverse effects from climate change and be better able to withstand
the unavoidable consequences that will result.
The majority of Australia‘s greenhouse gas emissions3 come from stationary energy sources;
typically coal-fired electricity-generating power plants (Figure 1). In reducing greenhouse gas
emissions, Australia must focus its efforts primarily on the stationary energy sector. This
should encompass the whole energy industry, including the generation, transmission,
distribution and use of electricity.

Australia cannot continue to ignore the large inefficiencies in its electricity use. Figure 2
shows national per capita consumption for electricity and automotive fuel and for water in
Melbourne, plotted against national population. This demonstrates that while Australia‘s
population has more than doubled as of 2009 (206 percent of 1961 levels), the water
consumption in an urban centre (Melbourne) has decreased (73 percent of 1961 levels),
personal vehicle fuel use has remained largely constant since 1980 (currently 191 percent of
1961 levels) and per capita electricity use has increased dramatically (555 percent of 1961
levels). When combined with population growth, the total electricity consumption has
increased nearly twelve-fold since 1961 across Australia.

(Australia) and water (Melbourne only) versus population, 2009 levels relative to 1961
levels (Sources: ABARE, 2009, ABARE, 2010, ABS, 2008 and Melbourne Water).
There are a variety of factors that can be considered to have influenced this increase,
including the relative energy intensity of industries such as mining and also the relatively low
price of electricity in Australia. It should be noted however, that fuel switching from electricity
to gas means that per capita energy use would be higher than portrayed in Figure 2. Even
considering these factors, substantial efficiency gains can still be made cost effectively to
energy users and the industry. There is plenty of ‗low hanging fruit‘ available, as demand
management is not currently used effectively in Australia, even for peak use, which is a key
driver of infrastructure costs. The electricity sector in Australia can learn from international
approaches to stimulate efficiency and demand management that include regulation, pricing
reform and behaviour change programs, which together can form a comprehensive strategy
to reduce energy use.
Internationally, governments are responding to concern about climate change by changing
the way they manage energy generation, distribution and use. Energy efficiency, demand
management, pricing and utility incentives to promote efficiency are cost effective measures
to reduce energy demand and consumption. Consumers benefit from lower energy costs
through greater efficiency and energy utilities can benefit from reduced peak loads, which are
a major driver of their costs. A variety of regulatory initiatives have been developed
internationally to achieve these savings which could provide Australia with guidance on
potential opportunities.

California has achieved a levelling-out of per capita electricity demand for the past 30 years
(Figure 3) mostly as a result of a comprehensive demand management strategy to improve
efficiency, including building codes, comprehensive minimum energy efficiency standards for
appliances and incentives that mean energy utilities do not lose revenue from improved
efficiency of electricity use. Most notably, the California Public Utilities Commission has used
the rate decoupling mechanism to break the connection between increased energy
consumption and the revenue energy utilities earn thereby providing them with an incentive
to promote efficiency. It should be noted that other factors influenced the result seen in
California that distinguish it from other parts of the United States and from Australia,
including relatively high electricity prices and a less energy intensive industry profile, as well
as a more vertically-integrated electricity industry structure. Similarities in lifestyle, climate
and in the availability of gas however, suggests that the Californian experience provides a
valid case study for Victoria in responding to climate change.

Total electricity consumption in California and Australia 1961-2008 (Sources: ABARE
2008, ABS 2008; Energy Information Administration (US), Annual Energy Review
2007).
Demand management is an important but underutilised response in Australia to responding
to climate change. Implementing energy efficiency measures to reduce carbon pollution does
not have to be expensive. For example, a 2010 report by ClimateWorks Australia, based on
the methodology of McKinsey & Company, demonstrated that significant carbon abatement
opportunities can be achieved in Australia at negative net cost to the economy through
improved efficiency of electricity use (ClimateWorks Australia, 2010). According to this
analysis, a total of 249 MtCO2e of emissions could be reduced at cost of A$7.20 per tonne in
2020, on a societal basis, without major changes to the economy.
Efficiency is a tool of demand management, and is effective in reducing resource
consumption in circumstances where wastefulness occurs. However, efficiency itself is not
sufficient to reduce greenhouse gas emissions unless the wasteful systems of economic
productivity and personal lifestyle are addressed (Foran, 2009). A comprehensive demand
management strategy that addresses energy efficiency as well as behaviour change is
essential in bringing about the changes to economy and lifestyle that are required in
transitioning to a low carbon society.

An analysis of the patterns in electricity demand and its relationship with price indicates the
ways in which demand management strategies could be implemented and also the benefits
associated with them. Demand for electricity typically exhibits peak/off-peak cycles,
depending on air temperatures, time of day and season. During summer, highest
consumption usually occurs in the middle of the day and lowest consumption overnight
(Figure 4) driven by energy intensive air-conditioner use. In winter, there are typically two
demand peaks; one in the morning and one in the evening which correlate with the times
individuals leave and come home from work.

Figure 4 Electricity demand and price curves: i) winter weekday (8 July 2009); ii)
summer weekday (20 January 2009) (Source: AEMO, 2010).
Figure 4 also shows a strong relationship between price and demand where peaks in
demand during summer and winter drive the price of electricity. Provision of electricity during
periods of peak demand costs significantly more than base demand because more
expensive generators, such as gas-fired or hydroelectric power stations, are required to meet
demand. Analysis of price and demand in the National Electricity Market (NEM) indicates that
a very small amount of electricity demand (0.29 percent – about 25 hours of the year)
accounts for nearly 18 percent of the total wholesale cost of electricity annually, averaged
over 2001 - 2009 (See C.3: Figure 11). As well as influencing the cost of electricity
generation, peak demand also drives the cost of electricity distribution through the need for
investment in infrastructure to meet maximum demand. In Queensland, for example, large
increases in peak demand over the past decade has driven investment in distribution and
transmission infrastructure to ensure the grid can handle peak demand. This increase in
costs has led to a doubling of electricity prices, even as generation costs have fallen
(Townsend, 2010).
Demand management strategies, as reviewed in this report, have the potential to reduce
demand peaks as well as overall reductions in electricity use and carbon emissions and so
can play a vital role in meeting the challenge of climate change. The recommendations for
implementing demand management strategies in Part A.2 are elaborated on below. These
recommendations are based on the evaluation of different demand management strategies
and methods considered in detail in Part B and an evaluation of the Victorian context detailed
in Part C. Part D.2 provides a glossary for terminology and acronyms used in the report.
Page 9
A.4. Detailed recommendations
Recommendation 1: Implement retail electricity pricing that captures time-dependent
costs using smart meters. Time-variable price signals, and the smart meters that
enable them, provide consumers with an incentive to shift demand from peak periods
and also enable consumers to get feedback on their consumption, which is important
in reducing energy use.
A retail pricing structure that reflects the wholesale cost of electricity more accurately is a key
element in encouraging demand management among residential and small business
consumers, and time-of-use and real-time pricing will help to reduce peaks and lower
demand. For residential and small business consumers, the key recommendation is the
creation of a framework for energy retailers to offer a variety of pricing products, including
time-variable rates and the option of critical peak pricing4.Trials have found that time-variable
pricing is effective in demand shifting but not necessarily at reducing overall demand, at least
in isolation of any feedback on use. A smart meter rollout does allow, however, the capacity
for mechanisms that in conjunction with time-variable pricing can achieve reductions in
energy use. The most significant is the ability to provide consumers with detailed feedback
on their use, which can reduce overall demand by 5 - 15 percent. Feedback can be provided
directly through electronic In-Home Displays, or indirectly through a website or via energy
bills. In evaluating the effectiveness of smart meters, it is important to recognise the essential
role of feedback in changing energy use patterns. As a minimum, it is recommended that
consumers be able to access usage information on-line and that rebates be offered on the
purchase of In-Home Displays.
The introduction of time-variable pricing in Victoria is driven by the mandated rollout of smart
meters, which will give the electricity industry the ability to provide time-variable tariffs. The
Victorian government expects that the adoption of these rates will lead to the phasing out of
pricing rates that inhibit demand management (DSE, 2006). The Victorian Energy minister, in
March 2010, announced a moratorium on the introduction of time-variable pricing, although
the smart meter rollout will continue as planned. There are equity concerns that the
introduction of time-variable pricing and the rollout of smart meters could financially
disadvantage low-income households who will bear costs for the rollout of smart meters that
are disproportionately high relative to their energy use and also through facing higher prices
under time-variable pricing. In addressing the cost of smart meters to consumers, the most
straightforward option is to have the distributors directly compensate identified low-income
households for the costs of the smart meter rollout. The St Vincent de Paul Society and the
Consumer Utilities Advocacy Centre (CUAC) recommend that pricing principles be applied to
allocate the costs for the rollout to higher consumption households by only passing through
these costs once a certain consumption threshold has been reached (Johnston, 2010).
With regards to pricing, the concern is that time-variable pricing may be imposed on all
households and those who would be worse off would not be able to opt-out. While it has
been argued that market competition will ensure some retailers offer more straightforward
products for low-income consumers, this is not guaranteed because of the deregulated
nature of Victoria‘s retail energy market. It is therefore important that regulatory measures
4 Critical Peak Pricing (CPP) involves a discretionary number of high or ‗‗critical‘‘ price periods applied
on days where particularly high demand is forecast such as hot summer days. For more detail see
B.3.1.4.
Page 10
ensure time-variable pricing is an ‗opt-in‘ measure for those who would be adversely affected
and that simpler and more equitable contracts are provided by retailers.
Low-income households and pensioners currently receive concessions on their electricity
bills which can go some way towards ameliorating the adverse effects of time-variable
pricing, as well as the increased fixed service charges from the smart meter rollout. The St
Vincent de Paul Society identified that under variable pricing, affordability is no longer just
linked to a household‘s total consumption, but also to daily consumption patterns. A
percentage-based concession will not necessarily improve affordability for a household with
proportionally high peak consumption and so concessions need to be developed that
address the problem of households with high non-discretionary usage during peak-times
(Johnston, 2010).
In the development of variable pricing mechanisms, it is also important to consider their
interaction with carbon emissions and also the future scenario of a price on carbon. For
instance, in Victoria, load shifting from peak to off-peak could increase carbon emissions, as
base load is provided by brown coal, and peaks by more efficient gas powered plants, which
under a carbon price would lead to more expensive electricity. In the short term, the two
measures of carbon pricing and variable pricing may work against each other, but over time if
demand management strategies lead to avoided generator capacity, this could complement
a carbon price that would pressure inefficient plants to close.
Recommendation 2: Establish a comprehensive behaviour change strategy for
electricity use. Electricity has been treated as an infinite resource, as evidenced by the
massive growth in per capita use over the last fifty years. A strategy that encourages
responsible behaviour by the community would provide a signal that electricity
demand is too high. A broad-based strategy would involve persuasion campaigns
backed up by participatory decision-making and community programs.
Price signals play an important part in determining consumer consumption and efficiency, but
price in isolation is not enough to achieve behaviour change, particularly where consumers
are faced with mixed messages. Establishing energy efficient and low energy use behaviour
as social norms requires a comprehensive behaviour change strategy that includes pricing,
regulation, social marketing and other mechanisms, all providing consumers with a
consistent message.
In its Climate Change White Paper, the Victorian government announced a behaviour
change program that will build on the ‗black balloons‘ campaign. Encouraging ‗responsible‘
behaviour through advertising and public campaigns is an important part of raising
awareness, and the plan to encourage the adoption of a personal savings target similar to
the ‗Target 155‘ program for water is to be commended.
As well as encouraging positive behaviour, the program must address barriers to action that
consumers face to ensure changes in action. It is important that these persuasion campaigns
are followed up by community programs that encourage social and participatory learning and
address habitual behaviour. Behaviour change campaigns that encourage ‗responsible‘
behaviour need to be supported by programs that create the circumstances for ‗response-
ability‘. This has been something lacking the original ‗black balloons‘ campaign and which
should be addressed as part of the government‘s planned program. It is recommended this is
done through a strengthening and expansion of the Victorian Energy Saver Initiative, as
detailed in Recommendation 3.
Page 11
Recommendation 3: Provide an enabling framework for consumers to reduce
electricity use. In addition to efforts to promote ‘responsible’ behaviour, efforts need
to be made to ensure the circumstances for ‘response-ability’5 are also created; that
is, a framework that enables the community to translate their intentions into actions. A
plethora of schemes already exist that seek to reward good behaviour in this context,
but are collectively less effective than they could be. We recommend strengthening
and expanding the Victorian Energy Saver Incentive (ESI) scheme to support
consumer behaviour change.
As well as encouraging the public to enact different forms of ‗responsible‘ behaviour in their
electricity use, it is also important to address the context in which individuals act by creating
the right circumstances for ‗response-ability‘. The introduction of pricing that more clearly
reflects variable costs is one such policy, as are efficiency standards and incentive and
rebate schemes such as the Energy Saver Incentive (ESI) scheme. Efficiency standards
have been effective in bringing about ‗systematic‘ changes by improving the energy
efficiency of individual appliances or items. A comprehensive strategy must include these
systematic measures, but must also take a more ‗systemic‘ (or whole-system) approach that
looks to improve the efficiency of how consumers use products, not just the efficiency of the
products themselves.
The ESI scheme provides incentives to replace items like lighting and fridges, space and
water heating. The Victorian Government‘s Climate Change White Paper flags expanding the
scheme by doubling the initial target, including more products like air conditioning and
televisions and also enabling small and medium businesses to participate. The White Paper
also outlines plans for a single web portal to provide information and access to all State
rebates and incentives. This can address the barrier of ‗information overload‘ that leads to
inaction from consumers who are confused about what they are eligible for and also allows a
broader range of opportunities to be accessed. We consider that there may be greater scope
in the scheme to encourage systemic behaviour change and to address the context in which
consumers make decisions, thereby increasing the effectiveness of the scheme. Our
recommendations for improving the scheme include:
Increasing awareness of the ESI among the public and improving their engagement with
it. Using electricity bills to provide information on opportunities and also engaging
retailers to promote the benefits of the ESI would improve the public‘s knowledge of it.
Including additional items that can help consumers avoid energy consumption, such as
such as switchable power-boards, timers and motion-sensitive lighting products.
Encourage large retailers of efficient products, such as lighting and whitegoods, to
become accredited persons and simplify the generation of energy efficiency certificates at
the point of sale. Using retailers can reduce barriers to uptake, as consumers can
exercise their own choice over products and have the reassurance of the retailer‘s brand
presence.
In addressing the social equity issues that arise from the transition to time-variable pricing, a
targeted energy efficiency scheme can play a significant role in easing the burden on those
who would be most disadvantaged. Low-income households are exposed to energy
expenditure that is proportionally higher, and they also often have less energy efficient
5 For more on the meaning of this term, see: Fisher, F. 2006. Response ability: environment, health
and everyday transcendence, Elsternwick, Victoria, Vista Publications.
Page 12
housing and old or inefficient appliances. The ability of these households to respond to
variable prices is therefore limited by their inability to switch to more energy efficient
appliances due to the upfront capital investment required (Johnston, 2010). A directed
program to address the efficiency of housing and appliances can allow households to reduce
their energy demand and also reduce their exposure to higher peak pricing.
Recommendation 4: Provide incentives for the electricity industry to pursue demand
management. To effectively reduce electricity use in Victoria, the electricity
transmission and distribution industries need to be provided with strong incentives to
implement demand management programs. Regulatory incentives that have been
implemented internationally provide guidance.
To encourage electricity distributors to pursue demand management programs as
alternatives to massive network infrastructure investment, it is necessary to address the
financial barriers that limit action. Currently the Australian Energy Regulator (AER) provides
incentives for electricity distributors to implement demand management through the Demand
Management Incentive Scheme (DMIS) (AER, 2009a). The DMIS comprises a revenue
allowance which allows distributors to recover the costs of demand management initiatives
on a use-it-or-lose-it basis and also allows the distributor to recover forgone revenue as a
result of successful demand management initiatives (AER, 2009a). It is recommended that
these are continued and expanded and also complemented by findings from the behaviour
change literature to address non-financial barriers to actions among management.
As well as providing a means for cost and revenue recovery, it is important that regulation
provides positive incentives for demand management to motivate organisations. Incentive
schemes are effective and commonly used approaches that go beyond cost recovery
measures. By linking efficiency to shareholder rates of return, these schemes encourage
organisations to see demand management as a central part of the business. Possible
options for schemes include Cost Capitalisation, where the distributor is provided with an
opportunity to earn a rate of return on demand management investments equal to other
capital investments, or Performance Target Incentives, where organisations receive financial
rewards for achieving savings targets.
In 2007, California introduced ‗decoupling plus‘; this provides revenue decoupling6 for cost
recovery as well as the ‗plus‘ of performance incentives for meeting or exceeding energy
efficiency targets. This, in effect, pays utilities for energy they have conserved. The provision
of incentives provides motivation and positive reinforcement to organisations, which can
address the non-financial barriers to action. In Australia, distribution and retail businesses in
electricity are disaggregated, which presents institutional difficulties for implementing such
incentives; however, there is still scope for a similar mechanism to be employed for
distributors. It is recommended that the regulator consider some form of incentive scheme to
build upon the existing DMIS structure that clearly links profitability and shareholder
performance with efficiency.
6 Revenue decoupling addresses the incentive utilities have to maximise revenue through increasing
consumption over promoting efficiency and the revenue ‗losses‘ experienced through implementing
DM. Revenue is ‗decoupling‘ from sales through annual rate-making adjustments that ensure utilities
collect an agreed-upon level of revenue.

Recommendation 5: Embed environmental concerns in the strategic focus of the
regulators. The priorities of the agencies that regulate and manage the National
Electricity Market are almost solely focused on price, quality, safety, security and
reliability of supply. Consumer advocacy issues are addressed in a limited way, and
environmental issues are not considered at all. We recommend embedding the goals
of environmental protection and the transition to a low carbon society as priorities of
the National Electricity Market in order to facilitate a transition to a more sustainable
electricity supply regime.
The Australian Energy Regulator (AER) is responsible for regulating the wholesale electricity
market and the economic aspects of electricity transmission and distribution. The AER
operates according to the National Electricity Objective, which is:
To promote efficient investment in, and efficient operation and use of, electricity
services for the long term interests of consumers of electricity with respect to –
a. price, quality, safety, reliability, and security of supply of electricity; and
b. the reliability, safety and security of the national electricity system.
The Australian Energy Market Commission (AEMC) makes the rules by which the National
Electricity Market operates. The AEMC hosts two advisory panels: 1) the Reliability Panel,
which deals with the reliability, safety and security of the electricity system; and 2) the
Consumer Advocacy Panel, which provides grants to consumer advocacy groups to conduct
research and support policy and decision-making. It is recommended that the National
Electricity Objective, which guides the regulator‘s actions, be updated to specifically include
the goals of achieving environmental protection and carbon reduction on an equal footing
with economic and consumer oriented objectives. To embed these goals into the
organisational culture that implements the regulatory framework, it is also recommended that
a third ‗environment and sustainability‘ board is established in the AEMC on similar grounds
to the Reliability panel, with the role of monitoring, reviewing and reporting on sustainability
concerns such as efficiency, greenhouse gas reduction, renewable energy and cogeneration.
In the United Kingdom, Ofgem regulates the operation of the electricity and gas markets.
Similarly to the AER, Ofgem was established following privatisation with the primary duty of
ensuring ‗the affordability, availability, security and quality of gas and electricity supplies‘ and
a principal objective to protect the interests of consumers. In response to the issues of
climate change and energy security, and in light of the need to transition towards a low
carbon economy, Ofgem‘s focus was refined. In 2000, it was given a duty to protect the
environment and in 2004 the duty to contribute to the achievement of sustainable
development was also added (Sustainable Development Commission, 2007). In 2008, the
Energy Act placed Ofgem‘s duty to contribute to sustainable development on an equal
footing with its other duties (Ofgem, 2010). The Act also refined Ofgem‘s principle objective,
being protecting the interests of consumers to refer to future as well as existing consumers
(Ofgem, 2010). In making its recommendations, the Sustainable Development Commission
referenced the case of California, where the energy regulator has also taken an active role in
pursuing efficiency and other positive environmental outcomes through interpreting its
general duties to protect consumers to include the promotion of a sustainable energy policy
(Sustainable Development Commission, 2007). Following the Energy Act‘s revision, Ofgem
was restructured with the creation of a new Sustainable Development Division that brought
together Environmental, Social and Consumer Policy (Sustainable Development
Commission, 2010).

PART B. DEMAND MANAGEMENT MEASURES
B.1. Summary
Australia cannot continue to ignore the large inefficiencies in its electricity use. It has been
recognised that even with a price signal for carbon provided by an emissions trading scheme
(ETS), market impediments may cause underinvestment in cost-effective demand
management and energy efficiency opportunities in the electricity sector. Complementary
measures to an ETS are available that will facilitate cost-effective reduction in electricity
consumption and subsequent reduction in greenhouse gas emissions.
This part of the report is a review of best-practice demand management strategies both in
Australia and Internationally. The intended target was to review demand management
measures for the electricity sector; however, experiences in the water and transport sectors
were drawn upon where appropriate. Demand management strategies at the policy level
were reviewed and sub-divided into methods, which are relevant at the planning and
management level and are comprised of individual techniques for implementation.
The four broad strategies reviewed were pricing, smart operating systems, regulatory
measures and strategies for behaviour change. Pricing techniques include the use of time-
variable pricing that leads to demand reduction by providing more accurate price signals to
consumers. This strategy is complemented by smart operating systems, which include
technology like smart meters that enable time-variable pricing measures and In-Home
Displays that provide feedback on price and consumption to consumers. Regulatory
measures include incentives for the electricity industry to encourage demand management
spending. Other regulatory measures considered were energy efficiency regulations for
appliances. The section on strategies for behaviour change considers the models behind
energy consuming behaviour and techniques to bring about behaviour change, such as
social and community-based learning.
Page 15
B.2. Demand management strategies, methods and techniques
The fundamental objective of policies and regulation regarding demand management (DM) of
electricity is to positively influence consumer behaviour in regard to their energy usage. DM
is also referred to in the literature as demand-side management (DSM) and/or energy
conservation; however, we use the catch-all phrase ‗demand management‘ to describe any
technique that influences consumption of electricity. This section of the report presents a
review of demand management policies and regulations that have been designed to reduce
overall electricity consumption or reduce peak load.
Demand-side policies can be divided into four general strategies, as shown in Table 1. These
can be further defined at the management level as ‗methods‘, which are further made up of
‗techniques‘. In this section of the report, each of these strategies, methods and techniques
are described in detail, with examples given of their implementation.
Energy efficiency is often cited as a means of achieving reduction in electricity demand while
meeting consumer demand for services. This takes the assumption that demand for services
(e.g. refrigeration, television viewing) is the element in demand rather than the actual energy
needed to provide the service (Wirl, 1997). Energy efficiency can thus be broken down into
two elements; systematic and systemic:
Energy used for a particular item (systematic)
This refers to the rate of energy use for items with comparable utility. For example, a
compact fluorescent light can generate the same amount of light as an incandescent
bulb using fewer watts. Energy efficiency on this level is a ‗systematic‘ approach to
reducing electricity consumption that tries to reduce the energy consumption of all
items, typically through regulation (e.g. minimum efficiency standards).
Energy used to meet a human demand (systemic)
A household can replace all of its lights with low-energy compact fluorescent lights,
however, if many more lights than required to light an area are used, then the energy
efficiency is less than it could be. Similarly, a highly energy efficient refrigerator is less
efficient overall (at keeping food cold) if it has a much greater volume than needed.
Programs aimed at reducing electricity consumption through changing energy
behaviour and choice, are part of a more ‗systemic‘ (or whole-system) approach.
In this report, we pick up energy efficiency through demand management strategies. The
‗systematic‘ aspects of energy efficiency are dealt with under regulation, and the ‗systemic‘
aspects come under behaviour change strategies.

B.3. Pricing
Price indicates the value of a resource and represents the cost of production and services to
provide the resource. In many cases, there are impacts generated by the production and
supply of a resource that are not included in its price; these are termed externalities. These
can be positive, such as the jobs and livelihoods of those living in energy producing regions;
or they can be negative, such as the emission of greenhouse gases and their effect on
climate. Traditionally, the generation, transmission and distribution of electricity have not
been priced to include negative externalities such as climate change, environmental
degradation, social inequities and intergenerational inequities.
B.3.1. Pricing structures
For consumers such as households and small businesses electricity is typically priced at a
fixed rate, where a guaranteed fixed price is assigned in advance of electricity consumption
and is only periodically redefined by a regulatory body. This pricing mechanism can inhibit
energy conservation as it hides the higher cost of using electricity at certain times, as well as
providing no disincentive for higher than ‗normal‘ levels of consumption. Alternatives to fixed-
rate pricing are described below that either limit peak electricity consumption, or are
designed to reduce overall electricity consumption.
B.3.1.1. Time-of-use variable pricing
Time-of-use (TOU) pricing is a technique where electricity is provided at variable prices
depending on demand. The simplest form of time-of-use pricing is peak/off-peak tariffs,
where electricity consumed for water heating between 11.00 pm and 7.00 am (in Victoria) is
charged at a lower rate than electricity consumed during the remaining period. Residential
trials show that TOU tariffs flatten loads profiles by moving usage from high-price periods to
low-price periods (Herter, 2007). A three-tier TOU pricing structure includes peak, shoulder
and off-peak periods, which are different for business days and non-business days and can
also differ for residential and non-residential customers (see Figure 5).
A basic TOU program can expect to yield peak reductions of approximately 5 percent
(Newsham and Bowker, 2010). While this appears relatively small, it has been estimated that
a reduction of 2–5 percent in system demand at peak times could reduce the spot price of
electricity by 50 percent or more (Rosenzweig et al., 2003). This may have a significant effect
on wholesale prices in Victoria, as the top 0.29 percent peak of annual electricity
consumption represents nearly 18 percent of the total annual wholesale cost of electricity
(Figure 11). TOU may not be effective in reducing electricity costs where demand shifting or
reduction leads to the avoidance of highest bids in the spot market. While this could lower
average prices if it leads to avoided generation investment in expensive peak-load supply, it
could increase prices where generators not only need to maintain capacity but also have less
volume over which to ensure their overall profitability. Table 2, over-page, summarises
demand responses from a range of TOU trials.
The California State-wide Pricing Pilot included 1,861 residential customers assigned to
different tariff structures. A control group of 553 participants had the standard flat tariff and
252 participants had a standard flat tariff but were provided with information about reducing
loads in peak times and notified of peak days. The result in Table 2 was yielded by groups of
200 participants who were subject to seasonal TOU tariffs and another 856 participants who
had a TOU tariff and also some form of CPP tariff. (NERA Economic Consulting, 2008b).

In Ontario, the Smart Price Pilot was run by the Ontario Energy Board. 124 participants were
subject to a TOU tariff and were not informed of critical peak events, another 124 participants
were on a TOU tariff with a CPP element and a third group of 125 participants were on a
TOU tariff and received a ‗critical peak rebate‘ for reducing use below a baseline during peak
periods (NERA Economic Consulting, 2008b). Also in Ontario, the utility Hydro One‘s time-of-
use pilot which took place in 2007 and involved 486 customers. Of these, 153 customers had
TOU rates and were also given In-Home Displays (IHDs), 177 customers had only TOU rates
and 81 customers only IHDs (Faruqui et al., 2010).
In Australia, Integral Energy, Energex and EnergyAustralia have recently conducted TOU
trials. Integral‘s involved 900 participants in three groups; 300 had seasonal TOU tariffs, the
second 300 were on TOU tariffs with critical peak pricing as was the third group, which was
also provided with In-Home Displays. Participants in the trial were also provided with access
to a web site which provided information on consumption and pricing. Energex conducted a
trial in Brisbane that involved 370 participants in five groups subject to a TOU tariff with and
without timers to switch off appliances during peak times, and direct load control
mechanisms (NERA Economic Consulting, 2008b). EnergyAustralia‘s trial included an
information-only group of 99 households, a TOU group of 108 households and three CPP
groups, with and without IHDs and at different rates. Domestic CPP saw positive results but
there were no clear results from TOU rates or from the addition of IHDs (NERA Economic
Consulting, 2008b).
TOU has been effective in load shifting but is not as effective at reducing overall energy use
as consumers are encouraged to shift usage but not necessarily to avoid consumption
(Newsham and Bowker, 2010). The ability to shift loads depends on the consumers‘ load
profile and also on their energy use, household size and appliance mix (NERA Economic
Consulting, 2008b). Consumers who have the ability to shift demand from peak to off-peak
periods will be better off under a TOU tariff because they will pay an off-peak rate that is
lower than the average flat rate tariff. Consumers who are unable to shift demand may be
better or worse off depending on what proportion of their load is peak and off-peak (NERA
Economic Consulting, 2008b).
Page 19
There is a risk of low-income households being exposed to greater vulnerability under TOU
pricing, particularly in the case where pensioners, young families and the unemployed are at
home during peak times. Other issues of concern are that low-income households own older
and less efficient appliances and live in older houses that require greater heating and cooling
and may not have access to mains gas (McGann and Moss, 2010).
B.3.1.2. Real-time pricing
More sophisticated variable pricing uses smart meters (discussed in more detail in Section
B.4.1) so electricity prices can respond to real-time demand. Real-time pricing (RTP)
involves price changing regularly to reflect underlying wholesale costs, which provide
accurate price signals to consumers. Real-time pricing can make electricity markets more
efficient by reducing wholesale price spikes, which in turn could reduce consumers‘ electricity
bills by lowering the average price of wholesale energy (Horowitz, 2007). Figure 5
demonstrates how real-time pricing would compare to other pricing structures.
Questions have been raised about the negative impacts of real-time pricing on consumers
through the exposure to variability and high prices during peak periods. However, economic
research suggests price volatility can actually be reduced under RTP as it reduces spikes in
the wholesale electricity market (Horowitz, 2007). Even with some short-term exposure to
spikes, real-time pricing should in principle lead to long-term savings for consumers over
traditional fixed pricing, which involves higher average costs. Price volatility on consumers‘
electricity bills can also be reduced through risk-management products like long-term
contracts and financial hedges (Horowitz, 2007).
While the cost of implementing real-time pricing, through the roll out of smart meters, is large,
the potential gains are considered to be many times the costs. It has been estimated that
one-half of savings from RTP could result from only one-third of users adopting the
mechanism (Borenstein, 2009). Real-time pricing is not as cost-effective for residential and
small consumers because they tend to have less capacity to shift loads and will bear higher
per capita costs for metering. US studies suggest that initially only large consumers should
be offered real-time pricing, either on a voluntary or mandatory basis (Horowitz, 2007).
However, this conclusion is not supported by the Australian experience where commercial
users have had access to time-variable rates since the deregulation of the industry but
uptake has been negligible, likely because businesses are unwilling to expose themselves to
variability in prices.
Time-of-use and real time pricing can shift demand to off peak periods, which means that
additional generation capacity does not need to be switched on to meet demand. This
reduces the cost of providing electricity, as this additional generation is significantly more
expensive than base-load supply. However these efficiency gains and the smoothing out of
peaks will not necessarily lead to reduced energy consumption or other environmental
benefits. Consumers‘ exposure to more accurate and higher peak prices may act as a
disincentive to energy use, but could also simply move demand to other times (e.g. running a
dishwasher overnight), in which case there is no net reduction in demand. Furthermore, the
electricity supplied during off-peak periods is generated by base-load coal (in Victoria), which
emits more greenhouse gases than peak generators (typically natural gas) (Holland and
Mansur, 2007).

B.3.1.3. Pre-paid electricity
Pre-paid electricity programs have traditionally been offered to consumers with poor credit,
and in the United Kingdom for rental property tenants. In the developing world, South Africa
has had considerable success in implementing pre-paid electricity to address the particular
issues of supplying power to remote communities where account management, meter
reading and billing are difficult (Tewari and Shah, 2003).
The applicability of pre-paid electricity as a demand management tool has been highlighted
by recent studies assessing the impact of In-Home Displays (IHDs) (see Section B.4.1.2).
The direct feedback provided by IHDs encourages consumers to make more efficient use of
energy with case studies from North America showing an average energy saving of 7
percent. When IHDs were combined with an pre-paid electricity program, energy savings
were found to be about twice that amount (Faruqui et al., 2010). These studies highlight the
importance of user-friendly feedback on consumption as a demand management driver that
is effective with time-of-use, real-time or pre-paid pricing structures (Darby, 2006). The
added savings seen in the above studies suggest that the consistent feedback and decision-
making required on a pre-paid plan make it an effective demand management tool, although
it should be noted that pre-paid pricing is currently banned in Victoria on equity grounds.
B.3.1.4. Critical-peak pricing
Real-time pricing (RTP) is effective at reflecting marginal wholesale costs; however there is
concern that RTP may be too complex for users and some regulators are reluctant to allow
residential customers to face the inherently volatile wholesale market. Where dynamic rates
are being considered but RTP is deemed infeasible for residential customers, an alternative
is critical-peak pricing (CPP).
CPP tariffs add to a TOU rate structure a discretionary number of high or ‗‗critical‘‘ price
periods that apply in times of system stress, such as very hot summer days (see Figure 5).
The critical price is applied on a limited number of ―event‖ days per year, based on utility
forecasts of a particularly high demand. Customers receive notification of the high price,
normally one day in advance, and in some cases are provided with direct load control
technology that automates the response of appliances like air conditioners (see Section
B.4.2). Compared to the ‗standard‘ TOU rate, the ratio of peak to off-peak price is higher on
CPP event days and the same rate is applied on every event day. The CPP price rate is
preset and so CPP is not as economically efficient as RTP in responding to demand, but also
bears less risk and variability than RTP (Herter, 2007). One issue that could arise with CPP
rates and their effectiveness as a demand management tool is the discrepancy between
retailer ‗price peaks‘ and distributor ‗demand peaks‘. If retailer-led CPP programs during the
summer pushes usage from the afternoon (when price peaks) into the evening (when
demand peaks) this would increase pressure on distributors. The Australian situation of
having disaggregated electricity distribution and retail companies could therefore limit the
effectiveness of CPP; however, trials here and overseas have seen positive results.
In the California State-wide Pilot Program, participants were exposed to a CPP tariff and
were not provided with any automated end-use controls. Under the CPP rate, prices were
discounted on non-critical days and participants were given information about how to
respond during critical high-price hours. On critical peak days in summer there was a 13.06
percent reduction in peak demand and 2.4 percent reduction in overall consumption. During
winter the outcomes were 3.91 percent and 0.62 percent respectively (NERA Economic
Consulting, 2008b). Demand response during CPP events averaged 5.1 percent; high-use
single-family homes responded with an average 7.8 percent reduction, while customers in
Page 22
apartments averaged 2.9 percent and low-use single-family homes 3.2 percent. Different
rates were tested and customer response to the $0.68/kWh critical-peak price was not higher
than response to the $0.50/kWh critical-peak price, which suggests that as discretionary
loads are curtailed, further curtailment becomes increasingly price inelastic (Herter and
Wayland, 2010).
Trials conducted in Australia have found higher levels of energy conservation on CPP days
than were observed in the Californian Pilot. Country Energy found that it achieved a 25
percent reduction in demand on CPP days and an 8 percent reduction in overall energy
consumption. Preliminary results in trials conducted by EnergyAustralia and Integral Energy
found reductions of between 7 and 15 percent. In both trials, demand was reduced as
opposed to just being deferred. It is suggested this is because a large amount of the critical
peak usage in Australia is driven by air conditioning, which would not necessarily be deferred
and so the energy that would otherwise have been used was saved (NERA Economic
Consulting, 2008b).
Members of NERA‘s focus group study on different pricing mechanism did not see much
benefit in adopting CPP. Views included that the need to change behaviour to avoid CPP
prices would impact adversely on people‘s way of life and there was no incentive to adopt a
CPP tariff in the first place. Direct Load Control (DLC) was preferred was a measure to
address high peak loads on hot days (NERA Economic Consulting, 2008b).
B.3.2. Consumer incentives
Consumer incentives from governments act as an enabling mechanism to encourage the
uptake of efficient technology. They aid in creating the circumstances for ‗response-ability‘ by
the public by addressing the financial barriers, such as relatively higher prices and longer
payback periods incurred by efficient technologies. The simplest incentives are direct rebates
and subsidies on the purchase of items or to reward efficient behaviour. Other measures
include low interest loans for the specific purpose of improving energy efficiency and also
energy certificates which are a market based mechanism that allow a financial benefit to be
gained from energy saving actions.
B.3.2.1. Rebate schemes and subsidies
In many international examples, governments assist households directly with implementing
highly cost-effective actions to reduce energy use. Examples of such actions, the ‗low
hanging fruit‘ of energy reduction, include compact fluorescent light bulbs, home insulation,
solar hot water systems, Energy Star rated appliances, electrical outlet timers, draught
stoppers, fridge and freezer seals, photovoltaic systems, wind turbines and other renewable
energy sources.
Determining the rate of a rebate offered is important. While high rebates can increase
participation and so give the appearance of success, they could lead to take-up being above
economically viable levels and even lead to premature and unnecessary replacement of
technology. High rates can also lead to an inequitable transfer of public money to
participants. Where a wide range of products are available in the scheme, the rebate rate
should be set on a dollar to energy or greenhouse gas saving basis to reflect the relative cost
effectiveness of each product (Geller et al., 2006).
In the United States, Federal tax credits were provided for energy efficiency measures by
households and businesses in the late 1970s and early 1980s. The credit reimbursed 15
percent of costs for households and 10 percent for businesses. Studies found the tax credits
scheme was not effective in encouraging the adoption of energy efficiency measures. It was
Page 23
concluded this was because of the small size of the credits and that the efficiency measures
that the credits applied to had already been widely adopted (Geller et al., 2006). The US
DOE provides grants for low-income households through the Weatherization Assistance
Program (WAP). The WAP has provided funds for five million households since 1976. The
program encouraged the development of home retrofit techniques and heating energy
consumption in participating households fell by around 30 percent (Geller et al., 2006).
In California, large-scale energy efficiency programs have run since 1977 (California Energy
Commission, 2009). As of 2002, total spending was estimated at about $230 million on
rebates for energy efficient technologies, free retrofits for low-income households and
technical development for industry. Energy efficiency schemes are estimated to have
reduced electricity use by the equivalent to 7 percent of the state‘s consumption and also
provided $2.7 billion in life-cycle benefits to consumers (Geller et al., 2006).
In Japan, tax incentives and low-interest loans are available for the construction of energy
efficient buildings and also for the purchase of energy-efficient equipment. Financial
incentives have led to the use of energy service companies (ESCO) for retrofit projects and
the market has grown rapidly with total value of projects growing from about 170 million yen
in 1998 to 665 million yen as of 2001 (Geller et al., 2006).
Many European nations have provided grants and/or tax incentives for energy efficiency
upgrades since the 1970s. In Sweden, low interest loans and grants improved energy
efficiency in housing and industry and also expanded the use of cogeneration. Innovative
energy efficiency measures that have been commercialised include a Swedish scheme that
involved bulk procurement to stimulate the market penetration of high-efficiency appliances,
windows and lighting products. This was complemented by social marketing, labelling and
voluntary standards (Geller et al., 2006).
B.3.2.2. Energy saving certificates
An energy saving, or ‗white‘ certificate (ESC) scheme involves setting mandatory energy
saving targets for energy distributors or suppliers that they are required to meet by
implementing specific energy-efficiency measures over a set period (such as Victoria‘s ESI
scheme – see Section C.4.1). The regulatory authority approves the technologies that qualify
for inclusion and also sets the targets that obliged parties must meet (Mundaca, 2008). The
energy savings are measured and verified using certificates that correspond to the absence
of emissions, for example 1 tonne of CO2 (Passey et al., 2008), and which are periodically
surrendered to the regulator to certify the energy saving. Each certificate is a traceable
commodity carrying a property right over a certain amount of additional energy savings and
guaranteeing that the benefit of these savings has not been accounted for elsewhere (Vine
and Hamrin, 2008). Parties have the option of trading certificates to meet their targets and
are penalised for non-compliance (Mundaca and Neij, 2009).
The objective of ESC schemes is to achieve mandatory energy savings at the least possible
cost. Theoretically this goal can be achieved effectively by granting the obliged parties
flexibility in the selection of eligible measures, end-use sectors and also in banking and
trading certificates. Flexibility is crucial because it allows parties to decide how to meet their
targets cost-effectively based on their particular marginal compliance costs (Mundaca and
Neij, 2009).The trading of certificates is not a necessary feature of schemes but enhances
the efficiency of a scheme through the equalization of marginal compliance costs among
obliged parties. Parties that can achieve significant energy savings inexpensively can
generate and supply surplus certificates to the market that can then be saved for future
periods or sold. Parties that find meeting their targets through direct action less cost effective
Page 24
can be better off buying certificates from other firms that may not have a target obligation but
have the capacity to undertake prescribed activities effectively. The regulator authorises
market agents such as ESCOs and retailers to implement measures that can generate
certificates, which can then be on sold to regulated parties (Mundaca, 2008). In theory, a
more ambitious saving target and greater variation in the costs of energy-saving measures
will increase the scope of a tradable certificate scheme to outperform other energy policy
instruments (Bertoldi et al., 2010).
In Europe, an evaluation of a British certificate scheme found that the energy saving and cost
effectiveness of the scheme was high, but this was in part because targets were relatively
low. The British, as well as Italian, schemes supported the distribution of technology that was
already commercially available and did not encourage the development of new technology;
however, more ambitious saving targets could yield a different scenario (Mundaca and Neij,
2009).
The most significant barrier to the use of ESCs is the problem of transaction costs, which are
additional costs imposed on parties in fulfilling their regulated obligations. These include the
costs of planning measures and then the costs of persuading customers to implement
measures. These were demanding tasks and, according to the suppliers, it became
increasingly difficult to find willing customers (Mundaca, 2007).
Barriers underlying the need for high transaction costs were primarily in the preliminary
stages of the scheme. These included a perception gap, where consumers believed the price
of efficiency measures to be considerably higher than it actually was, and the split-incentive
problem, where rental tenants were reluctant to implement measures because they would
not realise the financial savings. Lower income households were also less willing to invest in
energy efficiency measures because of a lack of readily available funds (Mundaca, 2007).
Generally apathy and lack of awareness were identified as major barriers and this suggests
that the performance of an ESC scheme depends on effective awareness-raising among
end-users (Mundaca, 2007). While the transaction costs associated with awareness-raising
and information provision can be high, these costs are considered necessary in increasing a
program‘s credibility and trust and the benefits from ESCs can exceed any incremental
transaction costs (Vine and Hamrin, 2008).
B.3.2.3. Green loans
Green loans are low-interest loans provided to households, businesses or industry
specifically for energy efficiency. Loans can address the high up-front costs of retrofits and
other measures. In Germany, the government provided low-interest loans to business and
industry in exchange for accepting voluntary targets to reduce CO2 emissions intensity. By
1998, a CO2 emissions reduction of 78 million tons, 9 percent of Germany‘s total CO2
emissions, was achieved and significant portion of this reduction was due to energy
efficiency improvements.
The Netherlands established a long-term agreements (LTA) program with industries that
together comprised over 90 percent of industrial energy use. Participating companies
developed and implemented energy efficiency plans and the government provided financial
assistance for the plans. The industries improved their energy efficiency by an average of
over 20 percent between 1989 and 2000, surpassing their targets in most cases. In 1999, the
Dutch government launched a new set of agreements that commit companies to achieve
‗‗best practice‘‘ energy performance in their sector worldwide by 2012 (Geller et al., 2006).
Page 25
B.3.2.4. Peak-time rebates
This is a mechanism that can be used as an alternative to critical-peak pricing. Consumers
receive rebates on their bills for not using power during peak periods, measured in relation to
a household-specific baseline. In an Ontario pilot study, a test group was subject to TOU
rates and during CPP event hours they received a 30 cent/kWh rebate for energy that was
not used and saw a 20% reduction during peak periods (Newsham and Bowker, 2010).
Page 26
B.4. Smart operating systems
Smart operating systems include a variety of technologies that enable more efficient energy
use. They include smart meters that can measures real-time energy consumption and
provide one-way or two-way communications between the energy supplier and the meter,
thereby enabling variable pricing mechanisms and In-Home Displays (IHDs) that provide
consumers with direct feedback on their usage, which can aid in reducing consumption.
Other technological initiatives include direct load control (DLC) technology that allows for the
remote switching of energy intensive appliances by utilities and also power factor correction
measures that improve the efficiency of energy provision to industrial users.
B.4.1. Metering
Traditional accumulation meters record energy consumption progressively over time and
require physical readings at set intervals to obtain the quantity of energy used during a billing
period. A technological advance on these are interval meters which record the quantity of
energy consumed over set, frequent time intervals. This feature allows interval meters to
provide time-varying energy pricing like TOU (see Section B.3.1).
B.4.1.1. Real-time electricity metering
Smart meters possess interval metering capability and also include one-way or two-way
communications between the energy supplier and the meter (Energy Futures Australia Pty
Ltd, 2008). This enables real time pricing, remote meter reading, connection and
disconnection, outage and tamper detection and the use of load control devices and In-Home
Displays (Energy Futures Australia Pty Ltd, 2008).
The benefits of smart meters include energy efficiency savings from time-variable pricing and
also business savings for distributors and retailers from automated metering and feedback,
improved asset management and usage forecasting and capital cost savings (NERA
Economic Consulting, 2008a). The costs of a widespread roll-out include the cost of
purchasing and installing the meters as well as the cost of upgrading billing and management
systems to process and store detailed usage data (NERA Economic Consulting, 2008a). One
analysis suggests that in Australia, the cost of a smart meter rollout could be justified on the
avoided meter reading costs and business efficiencies alone and that any network deferral
benefits or greenhouse gas emissions reductions would be an additional benefit (NERA
Economic Consulting, 2008a). This is consistent with North American case studies where
avoided meter readings were up to 68 percent of total benefits (NERA Economic Consulting,
2008a).
End-use consumers will benefit from the cost benefits of dynamic pricing, which can lead to
lower average pricing as well as improved billing accuracy and payment arrangements
(NERA Economic Consulting, 2008a). The major cost consumers‘ face is for the rollout of the
smart meters. In Victoria, where the rollout has commenced, customers will face charges
ranging from $158 to $271 to receive single-phase meters over the next two years, as
determined by the Australian Energy Regulator (AER) (AER, 2009b). The costs have raised
consumer protection concerns and it is important that existing hardship policies and
assistance schemes are not eroded and assistance is provided where needed (NERA
Economic Consulting, 2008a).
Smart meters enable the provision of tariffs and products that can lead to greater demand
management, but achieving the benefits of improved energy efficiency, cheaper energy and
lower GHG emissions rely on more than just the rollout of the meters (Neenan and Hemphill,
2008). Effective demand management relies on consumers engaging with the products that
Page 27
smart meters enable, which suggests that feedback mechanisms, like In-Home Displays,
education programs and a broader behaviour change strategy, are essential in getting the
most from smart meters (Neenan and Hemphill, 2008).
B.4.1.2. In-Home displays
In getting the most benefit from the roll-out of smart meters and the development of new
tariffs, the ability to engage consumers actively in energy usage decision-making is
important, as domestic energy consumption is largely invisible to users (Darby, 2006). It has
been argued that energy consumption can be reduced by providing consumers with more
information about their usage patterns (Wood and Newborough, 2003). This feedback can be
direct, through In-Home Displays (IHDs) that give users real time information, or it can be
indirect, most commonly through the use of informative billing (Darby, 2006). Savings have
been shown in the region of 5-15 percent and 0-10 percent for direct and indirect feedback
respectively (Darby, 2006). To be effective, displays must be accessible and provide clear
and useful feedback based on actual consumption. Other possible features are an appliance-
specific breakdown (enabled by smart home networks) and historical comparisons (Fischer,
2008).
Important factors to consider in designing IHDs to be effective include how best to motivate
users, how data should be presented and also where IHDs should be located within the
home. Information can be presented in kilowatts, dollar costs or GHG emissions, all of which
frame the problem in different ways and so appeal to different motives (Fischer, 2008). For
example, a traffic-light IHD system could represent off-peak, shoulder and peak pricing
periods with green, yellow and red lights respectively, which would result in different
behaviour to a traffic-light system that represents low use, moderate use and high use with
green, yellow and red respectively. The pricing-based traffic-light system could result in
consumers using more electricity when the lights are green, whereas the demand-based
system would encourage consumers to continue low demand when the lights are green. The
ability of users to interact actively and change their displays is important in allowing
individuals to focus on what motivates them. As a minimum, it has been proposed that IHDs
should provide instantaneous usage, expenditure and historic feedback with the potential for
displaying information on micro-generation, tariffs and carbon emissions (Darby, 2006).
Australian trials by retailers have found mixed results from IHD trials. Trials by
EnergyAustralia and Integral Energy found no significant difference between a group with
IHDs on a CPP tariff and groups with only a CPP tariff (NERA Economic Consulting, 2008b).
IHDs should also be compared to other channels such as web-based and bill-based
information that could provide more cost effective means to achieve effective feedback and
behaviour change. When the option of accessing similar information on the internet was
presented to NERA focus groups, it was preferred given its lack of any additional costs
(NERA Economic Consulting, 2008b). Trials by Country Energy in NSW also found that on-
going education was important regardless of whether consumers had IHDs (NERA Economic
Consulting, 2008b), which suggests that the provision of technology through a smart meter
and IHD rollout will not by itself lead to demand management outcomes and must be part of
a wider strategy that addresses tariffs, regulation and public awareness.
B.4.2. Direct load control
Direct load control (DLC) is a technological measure to reduce peak use that does not rely
on variable pricing, although it can be used in conjunction with it. Load control is initiated by
utilities who either contact consumers and request that particular appliances are turned off
during peak times or remotely switch off or adjust the setting of appliances through direct
Page 28
communication devices that are attached to appliances, such as air-conditioners and pool
pumps (Energy Futures Australia Pty Ltd, 2008). Load control methods can include
increasing thermostat set-points on air-conditioners, which gives an immediate large drop in
cooling load, and also limiting cycling run-time where air-conditioners are turned off for
incremental periods, which leads to a modest but more sustained decrease in demand
(Newsham and Bowker, 2010). Such control is used on specific high usage days, such as
hot summer days, determined in a similar way to CPP event days (Newsham and Bowker,
2010). Two-way communication between the utility and the controlled load is achieved
through a control device attached to a particular appliance. Smart meters and IHDs are also
useful for providing information on usage for DLC but are not essential (Energy Futures
Australia Pty Ltd, 2008).
Trials of DLC in Australia include a pilot study by ETSA Utilities in South Australia, which
resulted in a 17 percent reduction in peak demand from air conditioners in certain suburbs
(ETSA Utilities, 2008). Successive results from the ETSA trial concluded that outcomes were
dependant on location, housing type and air-conditioner technology and therefore not
necessarily effective. In Queensland, Energex found a 12 percent reduction in peak demand
and a 13 percent reduction in overall consumption for residential customers who were
provided with appliance timers that were set to switch appliances off during peak hours.
Energex also saw a 34 percent reduction in peak demand for customers who combined DLC
with a time of use tariff. The Californian State-wide Pilot Project resulted in a 43 percent
reduction in demand on critical peak days and a 27 percent reduction on non-peak days.
These results, for consumers who were on a combination of time of use tariffs and DLC,
were twice the reduction achieved by consumers who did not have DLC technology (NERA
Economic Consulting, 2008b).
NERA‗s consumer focus groups canvassed participants‘ views on DLC as well as tariff
structures like TOU and critical peak pricing. A consistent finding across the focus groups
was that participants were much more willing to consider DLC as an alternative to critical
peak pricing in specifically targeting peak summer days. Participants saw DLC as a means to
reduce electricity consumption that did not require active and constant decision-making. The
‗set and forget‘ option that allowed utilities to control appliances meant DLC did not impact on
their lifestyles (NERA Economic Consulting, 2008b).
B.4.3. Power factor correction
Electricity in an AC (mains) circuit consists of ‗Real power‘, which is measured in watts (W)
and is the power that translates into energy and ‗does the work‘, and also ‗Reactive power‘
which is measured in volt-amperes reactive (VAr) and is power that does not transfer energy
and so can be considered as wasted. While the current associated with reactive power does
no work at the load, conductors, transformers and generators must be sized to carry it.
Power factor measures the proportion of power that is being ‗wasted‘ as Reactive power. A
load with low power factor draws more current than a load with a high power factor for the
same amount of final energy transferred, which requires greater expenditure on wires and
other equipment. Because of these costs, utilities will usually charge a higher price to
industrial or commercial customers that have a low power factor.
Power factor correction (PFC), which is used to increase power factor, can be either passive
or active. Passive PFC uses a filter to improve load performance using capacitors or
inductors. Because of their high reliability and high power handling capability, passive power
factor correctors are normally used in high power line applications (Batarseh and Wei, 2007).
Page 29
An active power factor corrector uses high-frequency switching techniques to shape the
waveform of the electricity current (Batarseh and Wei, 2007).
Power factor correction programs have been run successfully in Australia, in South Australia
ETSA introduced voluntary power factor dependant tariffs that improved system power factor
by one percent in 2003 (ETSA Utilities, 2008). ETSA also identified a number of its largest
customers that were not compliant with minimum power factor standards and introduced an
Excess Incentive Charge from 1st July 2007 (ETSA Utilities, 2008). 120 customers
underwent power factor correction and the power factor for this group improved from 80
percent to 93 percent with 24 MVA of saved demand (ETSA Utilities, 2008). It should be
noted that there are no ongoing benefits from power factor correction and these savings can
only be a one-off.
Page 30
B.5. Regulation
B.5.1. Utility incentives
In many jurisdictions, governments and regulatory commissions require utilities to engage in
energy efficiency and demand management (DM) projects. In the United States, this
approach has contributed significantly to successful energy efficiency outcomes and the
scope for substantial outcomes in other places is high. Utility incentives seek to address the
barriers that have, in the past, limited the implementation of DM, namely the financial
incentive to encourage consumption and the costs involved with the implementing capital-
intensive infrastructure projects.
Three areas addressed by different techniques are: 1) allowing utilities to recover the costs of
implementing DM programs; 2) dealing with the problem of decreased revenue from
efficiency improvements; and 3) providing opportunities for shareholder earnings linked to
the performance of energy efficiency programs to encourage management action. Cost
recovery is most commonly achieved through including charges on consumer bills such as
system benefit charges. The problem of lost sales revenue can be addressed through ‘rate
decoupling‘ of profit from sales volume, while enabling the utility to recover agreed-upon
fixed costs (Kushler et al., 2006). In Victoria‘s deregulated energy system, where there are
no ‗utilities‘ but rather disaggregated generators, distributors and retailers, these methods
apply specifically to distributors. As distributors do not deal directly with customers, their
applicability may be limited under the current regime.
B.5.1.1. Rate decoupling
Rate decoupling addresses the incentive utilities have to maximise revenue through
increasing consumption over promoting efficiency and the revenue ‗losses‘ experienced
through implementing DM. By ‗decoupling‘ the profit a utility earns from its sales, the utility
has greater incentive to pursue efficiency measures and DM. Decoupling is achieved through
annual rate-making adjustments that ensure utilities collect an agreed-upon level of revenue
independent of actual sales (Eto et al., 1997).
Network economic regulation can broadly be divided into price cap and revenue cap forms:
Under a price cap, network businesses (i.e. transmission and distribution) are
subject to a maximum price per unit of electricity that is in place for a specified period.
This means that the network business‘ revenue will increase where more units of
electricity are sold. Businesses are encouraged to increase consumption and revenue
for the reason that the costs incurred by network businesses are generally comprised
of large capital costs and relatively low operating costs. This means that the marginal
revenue from each additional unit of energy sold will be larger than the marginal cost
of supplying it and so can deliver additional profit to the network businesses (Institute
for Sustainable Futures and Regulatory Assistance Project, 2008).
Under a revenue cap, the total revenue a utility is allowed to earn is fixed at the
beginning of the regulatory period. With this form of regulation, selling more units of
electricity does not lead to greater revenue, but can increase costs. To remain
profitable and also stay within the revenue cap, the network business has the
incentive to reduce the unit price of electricity by reducing costs. This has the effect of
encouraging cost-effective efficiency measures, particularly as an alternative to
supply side solutions and also breaks the connection between higher sales and
higher profit that acts as a disincentive to DM (Institute for Sustainable Futures and
Regulatory Assistance Project, 2008).
Page 31
The Australian Energy Market Commission (AEMC) in a recent review of DM methodologies
favoured price cap regulation over revenue cap regulation for distribution companies (AEMC,
2009a). The AEMC prefers the price cap as this method emulates the competitive market
where prices reflect the marginal cost of production (AEMC, 2009a). The AEMC recognises
that this ability to set the ―right‖ or market prices for efficient consumption through Time-of-
use or Real-time pricing is dependent on the roll-out of appropriate infrastructure in the form
of smart meters and In-Home Displays (Section B.4.1). To address the deficiency of the price
cap in regards to discouraging demand management the Australian Energy Regulator (AER)
has introduced a ‗foregone revenue component‘ to its Demand Management Incentive
Scheme (DMIS).
B.5.1.2. New South Wales D-Factor
Another regulatory tool that can address the issue of lost revenue and which has recently
been used in Australia is the NSW ―D-factor‖, which was introduced in 2004 after the revenue
cap in NSW was replaced by a price cap. The D-Factor allows distributors to increase their
prices to recover the cost of undertaking DM, up to the value of savings made in avoided
network costs. Distributors can also recover revenue losses arising from any decrease in
energy sales (Institute for Sustainable Futures and Regulatory Assistance Project, 2008).
Table 3 below shows the DM projects undertaken by each distributor in NSW from 2004/05
to 2006/07 along with the implementation costs and avoided distribution costs from each
project.

The DM projects undertaken since the introduction of the D-factor have allowed some
planned capital investment to be deferred and so created cost savings in the form of avoided
distribution costs. The avoided/deferred network costs averaged 6.5 times of the distributors‘
DM spending over the period. EnergyAustralia estimated that the DM measures implemented
delivered a reduction in peak demand of 64 MegaVolt Amperes (MVA) in the three years to
2006/07. The annual peak demand reduction achieved by Integral Energy‘s DM programs
were 31 MVA (IPART, 2008).
B.5.1.3. Systems benefit charges
A systems benefit charge (SBC) allows distribution companies to recover the costs of
implementing DM projects. These charges are calculated per kilowatt-hour (kWh) of usage
and are paid by ratepayers on their bills. They were developed after industry deregulation led
Page 32
to the phasing out of regulation-based DM that was applicable to integrated utilities. SBCs
are designed to fund energy efficiency programs and renewable energy programs, as well as
programs to assist low-income families and other public benefit activities (Harrington et al.,
2007). A SBC will not promote energy efficiency itself but provides a major source of funding
for various DM programs. The recipient of the funds raised is typically the one who
implemented DM activities. Where energy retailers or network businesses are the recipients,
they are able to carry out energy efficiency activities in a way that ensures they are
profitable, or at least revenue neutral (Energy Futures Australia Pty Ltd, 2000). The SBC rate
is usually set based on historic utility DM energy efficiency spending. Studies from the United
States have found that the funds collected by SBCs have been less per annum than what
had been spent on efficiency by previously integrated utilities, which traditionally had a
stronger regulatory mandate to pursue energy efficiency (Harrington et al., 2007).
Public system benefits charges have attracted criticism as they increase the price of
electricity for all customers. This has been considered as going against one of the purposes
of industry and market reform and also raises equity concerns. A price increase could also
impact on socially disadvantaged groups who may not benefit from programs funded by the
public benefits charge, while still paying higher electricity prices. This can be addressed by
specifically targeting programs to disadvantaged groups. For example, in Belgium, the
government allocates funds raised by the SBC to social programs to ensure that
disadvantaged groups are not disproportionately affected by increased electricity prices
(Energy Futures Australia Pty Ltd, 2000).
B.5.1.4. Shareholder incentives
In addition to providing a means for cost recovery, it is important that regulation provides
positive incentives for demand management. Even with decoupling in place, utilities may not
necessarily place demand management on an equal footing with supply-side investment.
Incentive schemes have become the preferred approach in the United States for addressing
this barrier and have proved to be effective (Institute for Sustainable Futures and Regulatory
Assistance Project, 2008). Shareholder incentives are a commonly used approach that goes
beyond program cost recovery measures. They can be easier to implement than other lost
revenue recovery mechanisms and can provide both revenue recovery and also performance
incentives for utilities. Various approaches that have been used in the United States include
(Kushler et al., 2006) & (Cappers et al., 2009):
Cost Capitalisation: The utility is provided with an opportunity to earn a rate of return on
DM investment equal to other capital investments. Authorised expenditures are
capitalised and the utility earns a return from them. Several states in the US that allowed
capitalisation for energy efficiency have offered a bonus or premium rate of return on
these investments.
Performance Target Incentive Mechanism: For meeting efficiency related performance
goals such as a savings target, the utility receives specific financial rewards and may be
financially penalised for not meeting targets. The utility may only qualify to receive the
incentive if it achieves a minimum level of the proposed savings target and further
payments may be linked to specific levels of performance. This incentive could be applied
to energy retailers in a disaggregated energy system.
Utilities can also be rewarded through receiving a proportionate share of the forecasted
net resource benefits that their DM programs generate.
Shareholder incentives provide senior management at utilities a strong signal to support
energy efficiency. For DM programs to succeed, a high degree of management commitment

is considered a key component. Research from the United States has found that objectives
and rewards should be simple, transparent and well-defined and also reward outcomes that
are within the control or influence of the business (Kushler et al., 2006).
B.5.1.5. Demand Bidding
In electricity markets with a wholesale ‗pool‘, electricity generators operate by nominating or
‗bidding‘ price levels at which it is profitable for them to sell electricity into the pool. Demand-
side bidding occurs when a consumer nominates a price level above which they are
prepared to reduce their demand for electricity, as their profit margins will decrease because
of the increased price. The demand-side bidder could be an energy retailer or a large energy
consumer buying straight from the pool (Energy Futures Australia Pty Ltd, 2000). In return for
making this reduction, the demand-side bidder would receive a financial benefit from their
energy retailer. They may also receive payment for being put on standby or shedding load.
Other customers also benefit from their actions, as the decrease in demand will mean the
wholesale price will not rise as much as it would have (Energy Futures Australia Pty Ltd,
2000).
Demand-side bidding does not necessarily promote energy efficiency and the most common
outcome is likely to be load shifting. Depending on the strategies adopted by customers, the
mechanism could increase or decrease consumer energy efficiency as prices drop.
Demand-side bidding has some drawbacks as it adds complexity to trading arrangements
and potential bidders could incur high transaction costs associated with managing their bids.
Demand reduction is also difficult to meter and it may not be possible to establish a baseline
amount against which reductions can be compared (Energy Futures Australia Pty Ltd, 2000).
B.5.1.6. Loading Order
A regulatory loading order is a tool that can provide a clear signal to the electricity sector that
all environmentally beneficial, cost-effective demand-side resources should be deployed
before the use of supply-side resources (Institute for Sustainable Futures and Regulatory
Assistance Project, 2008). The Energy Action Plan (EAP) adopted in 2003 by the California
Public Utilities Commission (CPUC), the California Energy Commission (CEC), and the
Consumer Power and Conservation Financing Authority (CPA) envisions a ―loading order‖ of
energy resources that will guide decisions made by the agencies jointly and singly. The
loading order rules that:
1. Firstly all strategies for increasing conservation and energy efficiency to minimise
increases in electricity and natural gas demand should be optimised.
2. The second priority for meeting demand is developing new generation capacity
using renewable energy resources and distributed generation.
3. The third priority is meeting demand through support for additional clean, fossil
fuel generation. In California these are benchmarked against modern gas-fired
plants (Harrington et al., 2007).
The Australian energy industry has been disaggregated and so in Victoria there are no
utilities as in California. The separation of generators, distributors and retailers means that
there are no entities to who all stages of the loading order could apply. It would be difficult to
implement a loading order and its introduction in Australia is unlikely, however the principle of
pursuing energy efficiency and demand management, followed by investment in renewable
energy before fossil fuel based supply side solutions are pursued, can provide a useful policy
guidance tool for government in moving towards a low-carbon society.

B.5.2. Efficiency
Energy-efficiency standards are regulations that prescribe the energy performance of
products (i.e. appliances, fittings, etc…), and can also prohibit the sale of certain products
that are considered too inefficient (Wiel and McMahon, 2003). Well designed standards can
lead to large energy savings in a cost effective manner and the resulting energy savings are
comparatively simple to quantify, and readily verified. One advantage of standards is that
they require a change in the behaviour of a manageable number of manufacturers instead of
the entire public (Wiel and McMahon, 2003). Standards can eliminate the least efficient
models on the market and also provide incentives for manufacturers to exceed standards to
gain competitive advantage. Labels that provide information to consumers and also stimulate
manufacturer innovation are integral to a standards scheme (Wiel and McMahon, 2003).
There are three types of energy-efficiency standards:
Prescriptive standards— these require that a particular feature or device is installed in all
new products;
Minimum energy-performance standards (MEPS)— prescribe minimum efficiencies or
maximum energy consumption that manufacturers must achieve in individual products;
and
Class-average standards—specify the average efficiency of a manufactured product
which allows manufacturers to achieve an overall target with a mix of higher and lower
efficiency products.
Deciding whether labels or standards should be legally binding is one aspect of designing a
scheme. Regulated energy efficiency is able to capture efficiency benefits that cannot be
provided by the market alone (Vine et al., 2003). Enforcing efficiency means all parties are
aware of the requirements and also ensures that a minimum level of performance is
achieved. However, this regulatory approach can only lead to moderate results as
compliance levels need to be relatively easy to achieve to gain widespread industry support
(Lee and Yik, 2004). For this reason, a regulatory approach is most effective for setting
MEPS that eliminate the least efficient models from the market (Wiel and McMahon, 2003).
Voluntary agreements can provide flexibility to industry in choosing how they reach targets
and also allow a more effective dialogue between industry and policy makers (Lee and Yik,
2004). Where manufacturers have information about technologies and costs that the
regulating authority lacks, it can be difficult to impose mandated standards on the industry
that are efficient. This scenario of information asymmetry can be better addressed by a
voluntary scheme (Menanteau, 2003). The voluntary approach also reduces enforcement
costs and can avoid duplicated private effort (Wu and Babcock, 1999). Firms have an
incentive to negotiate voluntary agreements to avoid the imposition of regulatory measures.
This means that for the agreements to be successful, the possibility of regulatory measures
should remain a realistic threat (Menanteau, 2003). To be successful, voluntary programs
need this strong statutory base and also measurable environmental objective and substantial
financial incentives (Wu and Babcock, 1999).
An analysis by the Allen Consulting Group illustrates the relationship between mandatory
and voluntary standards (Allen Consulting Group, 2008). A combination of regulatory and
voluntary instruments is seen as the most effective strategy. Regulation is used to create a
baseline level and then a voluntary scheme, using eco-labelling, providing incentives to
achieve levels above the minimum (Wiel and McMahon, 2003). The use of rebates to
encourage consumer take-up can also play a part in moving the market towards higher
efficiency by lowering the implementation costs of new technology (Lee and Yik, 2004).
Page 35
B.5.2.1. Mandated minimum efficiency standards
Minimum energy performance standards (MEPS) were introduced in Japan for refrigerators
and room air-conditioners and then subsequently expanded to include fluorescent lamps,
televisions, copying machines, computers and magnetic disk units. In 1998, the ‗Top Runner
Programme‘ required all new products (including imports) to meet the efficiency level of most
efficient product in the class (Geller et al., 2006).
In the United States, negotiations between manufacturers and efficiency advocates led to
laws for refrigerators, air conditioners, clothes washers, and other appliances which were
then extended to motors, heating and cooling equipment used in commercial buildings and
some types of lighting products. By 2000 these standards had cut national electricity use by
88 TWh or 2.5 percent (Geller et al., 2006).
B.5.2.2. Voluntary efficiency standards
In the United States, the EPA's ‗Green Lights‘ and ‗Energy Star Office Products‘ programs
encourage the adoption of cost-effective energy-efficient technologies that have low rates of
market adoption. The Energy Stars product labelling program informs US consumers of
appliances that are energy efficient. The label exists for a wide range of products, including
personal computers and other types of office equipment, kitchen and laundry appliances, air
conditioners and furnaces, windows, and lighting devices. It is estimated that the program in
aggregate has resulted in about 104 TWh of electricity savings as of 2002 (Geller et al.,
2006). Under Green Lights, EPA enters into voluntary memoranda of understanding (MOUs)
with for-profit firms and not-for-profit organisations for the implementation of energy-saving
lighting improvements. The program addresses the problem of market failure due to limited
information that impairs organisational decision making (Howarth et al., 2000).
Page 36
B.6. Behaviour change
Regulatory and pricing mechanisms form part of wider behaviour change strategies that
incorporate public awareness and engagement campaigns.
The behavioural assumption that underlies many different mechanisms, such as pricing, is
the rational economic model that suggests individuals look to maximise expected benefits to
themselves from their actions. The use of financial incentives therefore provides a way to
motivate individuals driven by this self-interest. Psychological and sociological research
points out that behaviour is influenced by a variety of social, political and cultural factors such
as norms, habits and technology, which add complexity to decision-making and requires the
need for more sophisticated behaviour change mechanisms. Mechanisms to encourage the
uptake of new behaviour include persuasion and information provision through labelling and
advertising, as well as more sophisticated trial and error based means such as participatory
problem-solving and community based social marketing.
B.6.1. Influences on behaviour
B.6.1.1. The rational economic model of behaviour
The basic tenet of the rational economic model is that individuals act to maximise the
expected benefits to themselves (Jackson, 2005). Behaviour therefore consists of making
deliberate choices based on factors such as income, personal tastes and available products.
When applied to energy efficiency, the rational-economic model attempts to persuade the
public to perform energy conservation where it is in their interests financially (Costanzo et al.,
1986). For example, long-life energy-saving lights can be more cost-effective over their life
than multiple incandescent bulbs. This is often coupled with government rebates or product-
swap schemes to cut the upfront cost, thus reducing a barrier to uptake.
To make decisions to maximise utility, consumers require market information. Energy
conservation has traditionally been framed as being of ‗information deficit‘, with the belief that
more information is the key to public involvement and action and the assumption that a
better-informed public will naturally change their behaviour (Owens, 2000). The rational-
economic model is considered intuitively reasonable, but information campaigns have not
always been successful in bringing about behaviour change. This outcome indicates that the
model does not address all the barriers to action (Owens, 2000). The rational-economic
model has been critiqued on the grounds that the assumption of rationality oversimplifies the
complexity of individual decision making (Costanzo et al., 1986). Individuals do not make
decisions in isolation and social interaction and norms play a part in how individuals create
identity and make decisions. Problems are framed in particular contexts, which impose
personal and institutional constraints on decisions (Owens, 2000).
It has also been argued that people are simply not capable of processing all the cognitive
information required for rational choices and so fall back on habitual behaviour, often guided
by emotional biases (Jackson, 2005). Energy consumption decisions are relatively low in
complexity and involvement and so do not require a lot of cognitive effort, which encourages
automated behaviour (Marechal, 2009). It has been found that even where new behaviour
carries substantial benefits to individuals, consumers are so ‗locked in‘ to consumption that
even after forming the intention to change behaviour, this will not occur because it
contradicts an existing habit (Marechal, 2009). Habits develop where there is repetition of
action and also stability of context or environment. Disrupting unsustainable habits is an
important initial step in behaviour change and it requires change in contextual cues and also
Page 37
time and repetition. Incentives must specifically address the short term rewards and the
social and structural influences that shape and maintain habits (Marechal, 2009).
B.6.1.2. Social-psychological factors and models
Behaviour is influenced by a variety of social, political and cultural factors such as norms,
habits and technology which shape and constrain individual choices. These are influenced by
the price of products, awareness of issues, trust in the provider of information and
commitment to change (Owens and Driffill, 2008). Using a psychological framework to
understand environmental behaviour within a social context, researchers have identified
three key factors that can be categorised as: the situational circumstances in which
individuals are placed (including socio-demographic situation), the socio-environmental
values individuals hold, and attitudes towards specific behaviours (Barr and Gilg, 2006).
Situational circumstances refer to the social composition of groups, defined by
demographics, disposable income, home ownership, structural characteristics such as
recycling provision in the community and situational factors such as knowledge of
environmental issues, and relevant technologies within the home (Barr and Gilg, 2006).
Models suggest that pro-environmental behaviour arises from quite specific value
orientations. Values regarding nature, such as biocentrism (viewing humans and nature as
equal) and anthropocentrism (viewing humans as dominant over nature), were found to be
clear indicators of behaviour, with bio-centric values being held by those who identified as
committed environmentalists and anthropocentric and techno-centric values held by non-
environmentalists (Barr and Gilg, 2006). As well as values regarding nature, wider social
values can play a role in distinguishing between groups of environmental actors. Using a
spectrum that ranged from ‗altruism–egoism‘ and ‗openness to change–conservatism‘, it was
found that those most likely to undertake environmental actions were ‗altruists‘ and ‗open to
change‘ (Barr and Gilg, 2006). While ecological values can have a significant impact on
environmental behaviour, they too must be put into a wider context. It is difficult to distinguish
values or attitude from contextual factors (such as social exclusion), which are an important
antecedent to attitudes (Jackson, 2005). Values will also vary within an individual according
to different contexts and situations. There has also been an observed attitude-behaviour gap
in studies of environmental actions, with reasons ranging from social context to the influence
of habitual behaviour (Jackson, 2005).
In regards to attitudes regarding specific environmental behaviour, intrinsic motivation and
personal satisfaction are considered important in achieving positive outcomes. Successful
outcomes have been found where individuals obtain a sense of inner satisfaction from their
actions and also where they believe their actions will result in tangible positive impacts on
society and the environment. Individuals who believe they can make a difference, and also
that they bear some responsibility for environmental problems, are more likely to be engaged
in environmental practices (Barr and Gilg, 2006).
B.6.2. Strategies for behaviour change
While consumer choices are influenced by a vast variety of factors, it has been found that
there are only a relatively limited number of avenues to influence behaviour change. Kaplan
(2000) makes a distinction between three different understandings of behavioural change: 1)
telling people what to do, 2) asking them what they want to do and 3) helping people
understand the issues and inviting them to explore possible solutions. These concepts are
not dissimilar to Arnstein‘s ‗ladder of participation‘, which considers eight rungs of
participation, grouped as non-participation, tokenism and citizen power (Arnstein, 1969).
Collins and Ison (2006) urge us to ‗jump off Arnstein‘s ladder‘ and place more emphasis on
Page 38
social learning. In the following sub-sections, we consider four models of participation:
information, consultation, participation and social learning.
B.6.2.1. Information
Many public conservation programs have taken the form of large-scale information
campaigns that are directed towards the voluntary conservation of energy by the general
public (Crossley, 1979). These actions are designed to increase awareness of energy use,
promote the need to reduce energy use and demonstrate ways that energy can be saved
(Crossley, 1979). These programs have relied on the rational-economic model and the
attitude model, which assumes that conservation behaviour will follow automatically from
favourable attitudes toward conservation (Costanzo et al., 1986). In the past, conservation
programs have focused on the attitude model, using costly advertising campaigns designed
to create favourable attitudes toward conservation (Costanzo et al., 1986).
The success of persuasion campaigns depend on the credibility of the source, the
persuasiveness of the message and also the responsiveness of the audience (Jackson,
2005). Campaigns have been found to be successful where the message is direct and
relevant to the audience and also emotional and imaginative appeal. Good campaigns also
feature identifying ‗retrieval cues‘ that can help people recollect the message, and also use
visible commitment mechanisms, such as bumper stickers, badges or loyalty schemes
(Jackson, 2005). Successful public awareness campaigns that have run in Australia include
the ‗Quit Smoking‘ campaign, and for water efficiency, the ‗Don‘t be a Wally with Water‘
program. In the field of energy efficiency, the ‗Black Balloons‘ campaign is a recent Victorian
example (Langford et al., 2008).
Awareness campaigns focus on establishing ‗responsible‘ behaviour among the public. It has
been found that the ‗top-down‘ provision of information commonly used is not always capable
of addressing the attitudes and values underlying behaviour and the imposition of more
information on consumers, particularly in a modern information intensive society, may simply
reinforce a sense of helplessness about the situation (Jackson, 2005). Approaches that seek
to encourage ‗responsible‘ behaviour need to be complemented by programs that create the
circumstances for ‗response-ability‘ (Fisher, 2006), or policies and programs that engage the
public to put new behaviours into action, such as incentive and rebate schemes. Information
persuasion campaigns are useful but that they should be part of a wider strategy (Owens and
Driffill, 2008).
B.6.2.2. Consultation and participation
Community-based social marketing has emerged as an alternative to information-intensive
campaigns, with the recognition that while information campaigns can be effective in creating
public awareness, they are limited in their ability to foster behaviour change (McKenzie-Mohr,
2000b). Community-based social marketing aims to bring people in a community together
and can be a powerful tool for policy makers to use to encourage pro-environmental
behaviours (Martiskainen, 2007). Community-based social marketing is composed of four
steps: uncovering barriers to behaviours and then, based upon this information, selecting
which behaviour to promote; designing a program to overcome the barriers to the selected
behaviour; piloting the program; and then evaluating it once it is broadly implemented.
The first step is to identify a specific behaviour and the various barriers it faces. Barriers can
be either internal, such as knowledge, skill or attitude, or external, such as a technology or
institutional barriers (McKenzie-Mohr, 2000b). One specific behaviour is targeted often within
a specific social group (McKenzie-Mohr, 2000b). The method allows for a cost benefit
analysis to consider and compare different strategies and identify the most efficient barrier to
Page 39
target (Jackson, 2005). At the design stage, a program is developed which removes as many
of the barriers to the selected behaviour as possible (McKenzie-Mohr, 2000a). Possible
programs include commitment strategies or incentives which can reinforce people‘s
intentions to engage in pro-environmental behaviour, and prompts, visual or an auditory aid
that remind people to carry out activities they are usually already receptive to (McKenzie-
Mohr, 2000a). Piloting at a small-scale is important, as it allows program designers to test
various strategies against one another and to refine strategies before implementation
(McKenzie-Mohr, 2000a). Community-based social marketing also stresses the evaluation of
implemented program as valuable for improving the strategy and gaining support for future
projects (McKenzie-Mohr, 2000a).
The participatory problem solving approach can be effective in addressing habitual barriers
that stem from social norms and as a result of social expectations. This is because the
process takes place in a group environment with communication among those involved in
negotiating the change, which can lead to the development of new social norms that can
impact habits (Kaplan, 2000).
B.6.2.3. Social learning
Information and consultation remain two of the most widely used ways of trying to influence
attitudes or behaviours, but they are among the least effective (Jackson, 2005). Such
methods focus on a transfer of knowledge from those who considered themselves informed
to those considered to be uninformed. Under these models, the ‗best‘ strategies are those
that are easily generalised and are therefore applicable to the widest audience. Thus, some
factors that may lead to the failure of these strategies include a lack of consideration of social
contextual factors, as well as a lack of engagement with, and even alienation of, groups
being targeted for behaviour change.
Alternative models of ‗behaviour change‘ focus on changes in understanding (learning) and
changes in practice that result from group (social) processes. ‗Social learning‘ can be
considered as a process of concerted action (or performance) that requires a convergence of
ideas, agreement on a way to progress among multiple stakeholders and conducive
institutional settings (Bommel et al., 2009, Pahl-Wostl et al., 2007).
B.6.3. Consumer information
B.6.3.1. Appliance Labelling
Appliance labelling provides information to consumers about the energy-using performance
of products (see also Section B.5.2 on efficiency standards). Traditionally, labelling programs
have been developed for products such as refrigerators, freezers, dishwashers and clothes
dryers, but are now being used on a wider variety of products and also to provide home
energy ratings (Energy Futures Australia Pty Ltd, 2000).
Designing an effective and independent energy labelling scheme involves considering a
range of technical, social and cultural issues, including how information is presented to
consumers, the format of the label and also the credibility of the labelling program sponsor
(Wiel and McMahon, 2003). It is important to consider all the stakeholders involved, including
manufacturers, retailers and consumers, and endeavouring to motivate all of them into action
(Energy Futures Australia Pty Ltd, 2000).
A label can provide a single rating or multiple measures of efficiency (Wiel and McMahon,
2003). There are two basic types of energy performance labels: Endorsement labels –
these provide an assurance from a reputable body that the product conforms to or exceeds a
minimum standard of energy efficiency; Comparison labels – these provide an indication of
Page 40
the level of energy efficiency of the product compared with similar products. This can be
indicated through an increasing number of ‗stars‘ or through the actual quantity of energy
used.
Labelling can address barriers to energy efficient behaviour through providing information to
consumers in a simple and consistent manner and their visibility encourages consumers to
consider energy use as a measure to compare products (Menanteau, 2003). A study
conducted in Shanghai found that consumers were prepared to pay more for energy
efficiency in products that are used more frequently, which suggests that the effect of the
energy label on consumers‘ choice may differ depending on the frequency of product usage
(Shen and Saijo, 2009). Energy performance labelling programs also put market pressure on
manufacturers to improve the energy efficiency of their products by providing incentives to
discontinue poor performing products and can promote differentiation and innovation among
manufacturers who wish to gain an edge in new market niches (Menanteau, 2003).
Europe‘s appliance labelling scheme was among the first and most successful of its
collective efficiency policies. The combination of labelling and the standards that took effect
in 1999 reduced the average electricity consumption of new refrigerators and freezers sold in
the EU by 27 percent between the early 1990s and 1999. Energy labelling led to a change of
the cold appliance market; it has been suggested that this stemmed less from a change in
consumer preferences and more from changes in manufacturer marketing strategies and in
resulting structure of sales (Menanteau, 2003).
The Australian Energy Rating Scheme was launched in 1986 for refrigerators and freezers,
and then later included dishwashers, air conditioners, clothes dryers and other appliances
(Energy Futures Australia Pty Ltd, 2000). The labels provide comparative information, with
an energy efficiency rating from 1 to 6 stars. In 1993, nearly 90 percent of appliance
purchasers said they were aware of the energy label and 45 percent said they used the
information to compare appliances prior to purchasing. About 42 percent of customers
reported energy efficiency or related factors as being the most important consideration in
appliance purchasing (Energy Futures Australia Pty Ltd, 2000).
B.6.3.2. Consumption information at billing
Providing information on energy usage on consumer bills or on the internet can be an
alternative to the rollout of In-Home Displays that can provide information and thereby
encourage behaviour change among consumers. The use of the bill as the information
medium is considered effective, as consumers must read it. The bill also provides the
opportunity to translate electricity usage into financial costs, making it more relevant to
consumers. Studies find that bill feedback is effective where feedback periods are relatively
short and where feedback is comparable to usage in a previous similar period or usage by
similar households (Energy Futures Australia Pty Ltd, 2000).
Where forms of informative billing have been implemented the indications are that
consumers do think about their electricity consumption and behaviour change has been
observed, particularly in the areas of space heating, lighting and water use. However,
consumption information on bills by itself will not address many of the barriers to energy
efficiency and behavioural change is only likely if the amount of the bill becomes an issue for
the customer. To achieve the broader goal of behaviour change, billing can be part of a wider
strategy including awareness and information programs and other social strategies (Energy
Futures Australia Pty Ltd, 2000).
Page 41
B.7. Conclusion
The fundamental objective of policies and regulation regarding demand management of
electricity is to positively influence consumer behaviour in regard to their energy usage. The
four general strategies of pricing, smart operating systems, regulation and behaviour change
should be seen as complementary in this objective. An effective program to engage the
public will incorporate methods and techniques from all four strategies which depend on each
other; for example, time-of-use pricing depends on the rollout of smart meters and to achieve
favourable outcomes this needs to be complemented by effective social marketing. From the
perspective of policy makers, there are three avenues for action that can be identified from
the techniques reviewed: 1) programs targeted at the electricity industry, including
generators and distributors; 2) programs targeted at manufacturers of energy using products;
and 3) programs that are targeted at the public, including industry, businesses and
households as energy consumers.
The major purpose behind the utility incentives assessed is to encourage electricity
distributors to pursue DM programs as an alternative to supply-side solutions. The principle
behind techniques such as decoupling, benefits charges and shareholder incentives is to
address the major financial barriers inhibiting DM, namely cost recovery of the costs of DM
programs, compensating for ‗lost revenue‘ resulting from efficiency improvements and
providing an opportunity for shareholder earnings from DM. The selection of particular
techniques will depend on context, but the basic principles of cost recovery and an incentive
structure which puts demand management on an equal footing with supply-side investment
are necessary to encourage industry action. Strategies that address the financial barriers to
DM should be complemented by conclusions from behaviour change literature to address
barriers related to bounded rationality and habitual behaviour among management. The use
of a strong regulatory tool, such as a loading order, can provide a clear signal to industry that
targets some of these behavioural barriers.
Manufacturers should be specifically targeted through energy-efficiency standards and
regulations. A well articulated mix of regulatory and voluntary instruments can remove cost-
ineffective, energy-wasting products from the marketplace and stimulate the development of
cost-effective, energy efficient technology. Regulation is used to create a baseline or
minimum performance level, and then a voluntary scheme, using eco-labelling, provides an
incentive to achieve a standard above the minimum and shift the market toward higher
energy efficiency. Successful voluntary programs must also have a statutory base, a clear
and measurable environmental objective, and substantial financial incentive. The regulatory
threat must be permanent and credible to encourage companies to stimulate improvements
in energy efficiency. An efficiency standards policy should also be partnered with an effective
labelling scheme and also some form of rebate or energy saving certificate scheme.
Labelling addresses the barrier of information deficit in choosing appliances and an effective
rebate scheme can address the financial barriers to changing appliances as well as be part
of a wider social marketing push to address behaviour change.
A pricing structure that reflects the wholesale cost of electricity more accurately is a key
element in encouraging demand management among consumers. Time of use and real-time
pricing can reduce load spikes and peak usage, which can reduce the average wholesale
price of electricity. While the cost of implementing real-time pricing, through the roll out of
smart meters, is significant, the potential gains are considered to be many times the costs. It
has been estimated that one-half of the possible total surplus gain could result from putting
only one-third of all users on real-time pricing. The implementation of a voluntary and
relatively simplified TOU for householders and small business as an option in a suite of
Page 42
market offerings that retailers can offer means consumers who could benefit from TOU can
do so. A broad range of market offerings can also include voluntary tariffs that encourage
power factor correction and demand side bidding for industry as well as CPP tariffs. For
distribution companies, remote direct load control of air-conditioners and other energy
intensive equipment can be a relatively easy and ‗painless‘ way to reduce household
consumption that can even be done independently of a smart meter rollout. In the
introduction of time-variable pricing, regulators should ensure that issues of social equity are
addressed through providing options for low-income households to obtain tariffs that do not
disadvantage them further.
The implementation of time-variable pricing is dependent on the rollout of smart meters, the
cost of which could be justified on the avoided meter costs and business efficiencies alone.
The benefit of smart meters to consumers in providing different tariff products, and also as a
conduit for more detailed feedback on consumption, which can both lead to lower electricity
costs, means that in principle the short term cost associated with smart meters can be
justified.
While time-varying pricing programs have been effective in load shifting, which can reduce
costs, they are not very effective at reducing overall energy use. Smart meters can enable
greater reductions in energy use through their ability to allow more detailed feedback on
consumption. This can be achieved through In-Home Displays, and where these prove
costly, through information provided on bills and also via the internet. While feedback is
essential in getting the most out of a smart meter rollout, In-Home Displays may not be, if
similar results can be achieved more cost effectively.
The analysis of socio-psychological models of behaviour indicate that pricing and also
consumer incentives schemes like rebates and energy saving certificate (ESC) schemes,
while effective, are limited to the degree that consumption behaviour is not necessarily
always driven by rational decision-making. These techniques can be improved by
incorporating the lessons from more sophisticated behaviour models that consider the variety
of social, political and cultural factors and contexts such as cultural norms, routine habits and
technology, which shape and constrain people‘s choices and options. Effective schemes
must combine information provision with techniques that address specific contextual barriers
and also seek to break habitual behaviour through social and participatory learning.

PART C. THE VICTORIAN CONTEXT
C.1. Summary
In implementing demand management in the State of Victoria, it is important to understand
the structure of the electricity industry, the regulation of this industry and the institutional
arrangements that enhance or constrain demand management and energy efficiency. These
factors are paramount in determining whether demand management and efficiency
measures that have been successful overseas would succeed in the local context. There is a
high degree of institutional complexity in the ‗Victorian electricity managing system‘ that is
partly due to the disaggregation of electricity industry, and also the formation of the National
Electricity Market. This means that demand-side regulation that has worked in vertically
integrated electricity markets would not work in this environment, as each component of the
market does not have the incentive to reduce demand.
The complexity of the situation is exacerbated by the lack of political will regarding a
comprehensive response to climate change and the need to establish a transition pathway to
a post-carbon society that encompasses demand management. This political will can be
identified as a key factor in the success of jurisdictions such as California, but is sorely
lacking in Australia. The current electricity managing system is not fit for the purpose of
dealing with climate change by reducing electricity use, and with the postponement of an
Emissions Trading Scheme, there is little to drive a reduction in greenhouse gas emissions.
This has meant that Victoria is left with a piecemeal approach, comprised of isolated
programs at State and Federal level that look to overcome barriers and market failures;
however, the Victorian Government‘s Climate Change White Paper is a step in the right
direction.
Page 44
C.2. The Victorian electricity situation
Considering the Victorian electricity situation systemically (i.e. looking at the whole system)
improves understanding of some of the diverse stakeholder interests relating to the
economic, social and environmental aspects of electricity supply. This approach recognises
that each stakeholder holds a partial perspective on the situation and that by piecing these
together, a systemic understanding of the situation can be built (Ison, 2008). This is useful for
identifying unintended consequences and counterintuitive effects, which result from
interconnectedness between different parts of the system.
Piecing together a systemic understanding of the Victorian electricity situation requires a
review of the history of the situation, including industry reform and critical events, as well as
an assessment of institutional arrangements at the local, regional, state, national and
international levels. These range from international efforts to curb the emission of
greenhouse gases, to local initiatives to reduce the carbon footprint of local communities.
C.2.1. History of economic reform in the Victorian electricity sector
The generation and supply of electricity in Victoria was under the control of the State
Electricity Commission of Victoria (SECV) since 1921 until it was disaggregated in 1993. A
brief overview of these reforms is presented in Table 4.

C.2.2. The current Victorian electricity situation
A ‗system map‘ of the electricity system in Victoria was produced (Figure 6), showing the
organisations that control or influence the system (including industry, government and
interest groups), as well as the ‗non-organisations‘ (including policies, programs, projects)
which provide a perspective on the basis by which electricity is managed in Victoria.

C.3. Stakeholder analysis
Participants in the electricity situation in Victoria broadly include industry, government,
businesses, individuals and interest groups (as shown in Figure 6).
C.3.1. Industry
The structure of the Victorian electricity industry is divided into four roles: 1) generation; 2)
transmission; 3) distribution; and 4) retail. Figure 7 shows the structure of the industry, as of
October 2009. Generators form part of the National Electricity Market (NEM), which connects
Victoria, New South Wales, Queensland, South Australia and Tasmania into one electricity
grid (Figure 8). Tasmania is connected by BassLink; a submarine cable from Tasmania to
Victoria. The NEM is managed by the Australian Energy Market Operator (AEMO).

Figure 8 the National Electricity Market (NEM)7, (Source: AEMC Annual Report 2009)
A wholesale electricity market, such as that in Australia‘s National Electricity Market (NEM),
operates by generators selling electricity to electricity retailers or large commercial customers
directly. A feature of wholesale electricity markets is the ‗spot market‘, which relates to the
cost of providing an amount of electricity at a particular instant, as electricity cannot be stored
in meaningful quantities. This means that when there is high demand for electricity, extra
sources of generation need to be brought online. Spot pricing, which depends on the level of
electricity demand across the NEM, averaged (median) $25.59 per MW per half-hour period
(Figure 9), and $27.30 per MW during peak and $21.57 per MW during off-peak (Figure 10).
7 This map represents the general geographic coverage of the NEM; the NEM actually makes up
approximately 80 percent of Australia‘s electricity network infrastructure.

However, a very small amount of electricity demand (0.29 percent – about 25 hours of the
year) accounts for nearly 18 percent of the total wholesale cost of electricity annually,
averaged over 2001 - 2009 (Figure 11).

C.3.1.1. Generators
The registered capacity of power generation assets in Victoria predominantly comes from
thermal-coal generators (6545 MW), followed by gas (1861 MW), hydro (1774 MW), wind
(489 MW) and waste gas/biomass (~16 MW) (AEMO, 2009). Of the thermal-coal generators,
the four major suppliers are Loy Yang A power station (2120 MW), Hazelwood (1600 MW),
Yallourn (1480 MW) and Loy Yang B (1000 MW). While located in New South Wales, the
Murray 1 & 2 power stations (1500 MW) that are part of the Snowy Mountains Scheme are
allocated to Victoria on the NEM. Snowy Hydro also operates a gas turbine generator in
Victoria (312 MW).
C.3.1.2. Transmission businesses
Electricity transmission involves movement of electricity along high-voltage lines from power
stations to distribution networks. Transformers reduce the transmission voltage to allow it to
be transmitted to consumers via lower voltage distribution networks (DPI, 2010). In Victoria,
the 6,000 kilometre high-voltage transmission network is owned and maintained by SP
AusNet and is operated (as part of the National Electricity Market) by the Australian Energy
Market Operator (AEMO). Victoria‘s electricity transmission network is interconnected with
the other Eastern states through the NEM and electricity can be transported interstate via
transmission inter-connectors depending on demand (DPI, 2010).
C.3.1.3. Distribution businesses
Victoria‘s electricity distribution infrastructure consists of approximately 200,000 kilometres of
overhead power lines and underground cables (DPI, 2010). These lower voltage distribution
lines are fed by the high voltage transmission network (DPI, 2010). There are five electricity
Page 50
distribution areas in Victoria, three areas encompass Melbourne and the inner suburbs, and
two cover the outer suburban areas and regional Victoria (DPI, 2010). CitiPower own and
maintain a network in Melbourne's CBD and inner suburbs that covers approximately 157
square kilometres. SP AusNet is responsible for the eastern metropolitan area of Melbourne
and eastern Victoria. United Energy Distribution is responsible for homes and businesses in
the south-east Melbourne metropolitan area and the Mornington Peninsula. Jemena
Electricity Networks supplies electricity to the north-west greater metropolitan region of
Melbourne. Powercor Australia is the largest electricity distributor in Victoria and supplies
electricity to Melbourne's outer western suburbs and also regional and rural centres in the
central and western areas of the state such as Ballarat, Bendigo and Geelong (Switchwise,
2010). Services provided by distribution businesses account for approximately 40 percent of
the total bill for electricity customers (ESC, 2006).
In the Australia Energy Regulator‘s draft determination for Victorian distributors for the period
2011-2015, there are several findings that are pertinent in understanding the distributors‘
actions specifically regarding demand management. The AER noted that when it came to
capital expenditure for reinforcement, distributors over-estimated and underspent in the
previous regulatory period, and the estimates for the forthcoming 2011-2015 period were
also considerably higher than what had been previously spent. The AER, in its assessment,
rejected the distributors‘ estimates as not reasonable and instead relied on historical
spending as a guide (AER, 2010). The distributors‘ over-estimation of capital expenditure
and historically low spending on demand management and non-network alternatives
suggests that there is scope for the implementation of demand management programs and
also that institutional barriers exist regarding demand management.
In forecasting energy consumption for the forthcoming period, the distributors‘ estimates
depict a significant reduction from the long term trend. This forecast reduction in
consumption comes despite an estimated increase in peak demand and was also rejected by
the AER and the findings of VENCorp (now AEMO) (AER, 2010). The AER finds that the
distributors‘ also under-estimated demand in the previous regulatory period and its
explanation has bearing on the success of demand management programs. Under a price
cap form of regulation, the price of electricity that the distributor can charge is fixed. By
under-estimating sales the distributor is able to obtain a regulated price per unit to meet its
revenue requirements that is relatively high. Subsequently, when actual sales are made
above the estimate, the distributor is able to increase its overall revenue (AER, 2010). This
disincentive for demand management under the price cap has been highlighted by the AER
and is targeted by demand management techniques such as revenue decoupling which
replaces the price cap with a revenue cap (not supported by the AEMC) and where a price
cap is in place through revenue recovery mechanisms, such as the ‗foregone revenue
component‘ in the AER‘s DMIS for the forthcoming period.
Prior to 2009, the Essential Service Commission of Victoria (ESCV) was responsible for price
regulation of the distributors and for the 2006-2010 period provided a number of demand
management incentives for Victorian distributors. These included an allowance to fund trials
of demand management initiatives, as well as permitting funding of non-network alternatives
using cost savings from deferred capital expenditure (AER, 2009a). In 2009, the AER took
over the role of regulating distributors from the ESCV and it provides incentives for electricity
distributors to implement demand management through the Demand Management Incentive
Scheme (DMIS) (AER, 2009a). In December 2008, the AER published a proposed DMIS to
apply to Victorian distributors for the regulatory control period commencing 1 January 2011
(AER, 2009a).
Page 51
The DMIS comprised two components:
1. A demand management innovation allowance (DMIA), provided as a fixed amount of
revenue annually, which allows distributors to recover the costs of demand
management initiatives on a use-it-or-lose-it basis (AER, 2009a).
2. A forgone revenue component, which allows the distributor to recover forgone
revenue as a result of successful demand management initiatives. The forgone
revenue component was designed to mitigate the disincentive to undertake demand
management created by a price cap form of control.
C.3.1.4. Retailers
Thirteen retailers operate in the Victorian market, providing residential and small-business
customers with contracts for electricity supply. Electricity retailers are the main point-of-
contact for customers. The rate for electricity charged by the retailers includes the wholesale
cost of electricity generation, network costs (transmission and distribution), retailing costs
and mark-up.
In its review of the effectiveness of competition in the Victorian retail electricity market, the
AEMC found that there is effective competition and rivalry between retailers, and that entry
conditions do not inhibit competition (AEMC, 2007). The AEMC is required to review the
effectiveness of competition in the retail supply of electricity in each state and where
competition is found to be effective, the jurisdictions are to phase out retail price regulation.
The Victorian Government removed retail price regulation on 1 January 2009 and also
implemented other recommendations, including the monitoring and publishing of all standing
offers on the regulator‘s website (Johnston, 2010).
The AEMC report found that customers were far more willing to switch retailers if approached
through direct marketing than through individual investigation. This is a result of customer‘s
relative lack of interest in energy products, which gives a strong incentive to retailers to
actively market their products. This results in ―vigorous‖ marketing campaigns from retailers;
and given that there are a dozen or so retailers, could be perceived by customers as
intrusive (AEMC, 2008).
In a submission to the AEMC Victorian retail competition review, the Consumer Utilities
Advocacy Centre (CUAC) highlighted the trend of integration of retailers and generators
(termed ―gentailers‖ – examples include AGL or TRU) and the impact this might have on
retail competition (CUAC, 2007).
C.3.2. Victorian Government
With the reform of the Victorian electricity industry, the Victorian Government‘s role has
shifted from running the system (in the SECV days), to unbundling and privatising the
system.
The Victorian Department of Primary Industries (DPI) is responsible for Victoria‘s energy
policy, the goals of which are to ensure that the electricity system is safe, reliable, affordable
and sustainable (DNRE, 2002). The control that DPI has over electricity policy is somewhat
moderated by the disaggregated structure of the electricity industry, as well as the
emergence of the Australian Energy Regulator (AER), which operates at a national level.
The Essential Services Commission of Victoria (ESCV, www.esc.vic.gov.au) is responsible
for administering the Victorian Energy Efficiency Target (VEET) Scheme and the Victorian
Renewable Energy Target. Energy Safe Victoria‘s (www.esv.vic.gov.au) role in the electricity
Page 52
system is to deal with safety standards and compliance. The Victorian Environmental
Protection Agency (www.epa.vic.gov.au) regulates environmental pollution in Victoria.
Sustainability Victoria (www.sustainability.vic.gov.au) leads the implementation of energy
conservation measures in Victoria. Consumer complaints regarding the electricity system are
directed to the Energy and Water Ombudsman of Victoria (EWOV, www.ewov.com.au).
C.3.3. Federal Government
C.3.3.1. Ministerial Council on Energy
The Ministerial Council on Energy (MCE, www.mce.gov.au) was established by the Council
of Australian Governments (COAG) in 2001 to implement national energy policy. The MCE
comprises one member (typically the energy minister) from each State and Territory, and one
Commonwealth member. The MCE developed the policy for the reform of the National
Energy Market in December 2003 and set in motion the establishment of the Australian
Energy Regulator and the Australian Energy Market Commission (MCE, 2003). The MCE is
also directing the national roll-out of smart meters, including brokering an agreement on
‗National Minimum Functionality‘ for smart meters and a consistent national framework.
The MCE hosts an energy efficiency working group that is tasked with implementing the
National Framework for Energy Efficiency, part of which is the National Partnership
Agreement on Energy Efficiency that was signed by COAG in July 2009.
C.3.3.2. Australian Energy Regulator
The Australian Energy Regulator (AER, www.aer.gov.au), established in 2005, is responsible
for regulating the wholesale electricity market (of the NEM) and regulates the economic
aspects of electricity transmission and distribution. The AER is part of the Australian
Competition and Consumer Commission (ACCC) and is established under the Trade
Practices Act 1974 (Cth).
The AER enforces the ‗national electricity law‘ and ‗national electricity rules‘ by monitoring
the wholesale market and regulating the ‗natural monopoly‘ sectors, including transmission
and distribution networks.
C.3.3.3. Australian Energy Market Commission
The Australian Energy Market Commission (AEMC, www.aemc.gov.au) was established in
July 2005 and makes the rules by which the National Electricity Market operates. The AEMC
also advises the MCE on strategic and operational matters.
The AEMC hosts two advisory panels: 1) the Reliability Panel, which deals with the reliability,
safety and security of the electricity system; and 2) the Consumer Advocacy Panel, which
provides grants to consumer advocacy groups (see section C.3.4.2 of this report) to conduct
research and support policy and decision-making.
Under the direction of the MCE, the AEMC conducts regular reviews into competition
effectiveness, the setting of price caps, market performance, and system reliability. Special
reviews have dealt with such relevant topics as the effectiveness of market frameworks in
light of climate change (AEMC, 2009c) and demand-side participation (AEMC, 2009b). From
reading the final conclusions of the AEMC in the climate change review (and of other
reviews), it is apparent that the agenda of the AEMC is to protect the existing energy market
framework and to push for full retail competition across all States participating in the NEM.
C.3.3.4. Australian Energy Market Operator
Page 53
The Australian Energy Market Operator (AEMO, www.aemo.com.au), established on 1 July
2009, is 60 percent government and 40 percent industry owned and is responsible for
operating the NEM. This includes system operation (i.e. maintaining reliability and security of
supply) and operation of the wholesale spot market. AEMO also undertakes infrastructure
planning to ensure existing and expected demand is met (DPI, 2010).
C.3.4. Supporting and interest groups
Groups, networks and associations that support or have interest in the Victoria‘s electricity
system can be classified as industry associations, consumer rights groups or environmental
groups. The role of these groups is typically to support the rights of those who have a stake
in the electricity system and who are affected by decisions made by others in the system.
This includes industry representation, in order to reduce the number of contact points for
representations to those in charge of the system. This category also includes those affected
by decisions, that otherwise have no (or little) voice: including ‗the environment‘ and
individual consumers, particularly those with low socio-economic status.
C.3.4.1. Industry associations
Industry associations represent sectors of industry and try to influence government policy in
the interests of their members. It is notable that ‗energy‘ associations typically represent both
gas and electricity sectors, which could have consequences for issues that benefit one sector
to the detriment of the other (e.g. policies to shift electrical water heating to gas water
heating).
The Energy Retailers Association of Australia (ERAA) represents gas and electricity retailers
in the NEM (www.eraa.com.au). The Energy Supply Association of Australia (ESAA)
represents the stationary energy sector (i.e. gas and electricity) across Australia, inclusive of
renewable and fossil fuel sources (www.esaa.com.au). The Energy Networks Association
(ENA) represents gas and electricity distribution businesses across Australia
(www.ena.asn.au). The ENA have an interest in the development of ‗Smart Networks‘. The
Electrical Energy Society of Australia (EESA) is a subset of Engineering Australia that
encompasses practitioners in generation, transmission, distribution, and retail sectors of the
electricity industry across Australia. The EESA conducts professional development activities
and lobbying (www.eesa.asn.au). The Energy Users Association of Australia (EUAA)
represents larger electricity and gas users across Australia (www.euaa.com.au). The EUAA
are interested in climate change and energy efficiency issues, as their members are large
consumers of energy. The Energy Efficiency Council (www.eec.org.au) represents the non-
residential energy efficiency products and services industry.
C.3.4.2. Consumer rights groups
The role of consumer rights groups in the Victorian electricity system is to provide legal
advice to consumers, as well as to make submissions on electricity policy, especially policies
that will have an impact on low-income households. Some of the major consumer rights
groups active in electricity policy in Victoria are listed as follows.
The Consumer Utilities Action Centre (CUAC) specifically represents Victorian consumers on
issues of electricity, gas and water policy and regulation (www.cuac.org.au). The CUAC has
made a significant contribution to energy policy in Victoria since 2002, corresponding to the
period of full retail competition in electricity. The Consumer Action Law Centre (CALC)
provides free legal advice on a range of issues, including electricity, particularly to low-
income consumers (www.consumeraction.org.au). The Financial and Consumer Rights
Council (FCRC) represents practitioners in consumer rights and financial counselling
Page 54
(www.fcrc.org.au). The Victorian Council of Social Service (VCOSS) is the peak body
representing independent (non-government) social services in Victoria (www.vcoss.org.au).
C.3.4.3. Environmental groups
There are numerous environmental groups with an interest in energy policy, mostly focusing
on reducing greenhouse gas emissions through renewable energy and energy efficiency. A
selection of Victorian-based environmental groups with a significant presence in this field is
listed as follows.
The Central Victorian Greenhouse Alliance includes local councils, businesses and
community groups in Central Victoria and is striving for ‗Zero net emissions by 2020‘ through
renewable energy and energy efficiency (www.cvga.org.au). The group Beyond Zero
Emissions is an environmental organisation with the goal of 100 percent renewable energy
for Australia by 2020, focusing on the social change required to achieve this
(beyondzeroemissions.org). Beyond Zero Emissions is also a member of the Zero Emission
Network (www.zeroemissionnetwork.org), which is an independent alliance of similar groups.
The Environmental Defenders Office (Victoria) is a community legal service that is interested
in environmental issues (www.edo.org.au/edovic/). Environment Victoria
(www.environmentvictoria.org.au) is running a campaign on ‗Halving Our Emissions‘, which
includes a significant push for energy efficiency. EV also released a report in May 2010 that
described how Hazelwood power station could be replaced by a combination of new gas
turbine power generation and energy efficiency (Environment Victoria, 2010).The Alternative
Technology Association are advocates for renewable energy and have campaigns for
renewable energy feed-in tariffs, and are interested in the use of smart meters, especially for
micro-generation (www.ata.org.au). The Moreland Energy Foundation (www.mefl.com.au)
was established by Moreland City Council to continue the work of the Brunswick Electricity
Supply Department after the privatisation of electricity meant local council could no longer
provide energy supply services. The MEFL is also incorporated in the Northern Alliance for
Greenhouse Action (www.naga.org.au), which is a network of northern Melbourne councils
that coordinates action on greenhouse gas reduction.
Local councils also contribute to energy policy in Victoria. The Municipal Association of
Victoria (MAV) represents 70 Victorian councils and is interested in energy efficiency,
particularly more efficient street-lighting (www.mav.asn.au). The Victorian Local Government
Associate (www.vlga.org.au) also represents 58 councils in this space. Both organisations
are part of the ‗Public Lighting Taskforce‘ convened by the Department of Sustainability and
Environment.

C.4. Policies, Programs and Projects to reduce electricity use
C.4.1. The Victorian Energy Saver Incentive Scheme
The Victorian Energy Efficiency Targets Act 2007 sets out the Victorian Energy Efficiency
Target (VEET), the purpose of which is to ‗promote‘ the reduction of greenhouse gas
emissions, encourage the efficient use of electricity and gas and to encourage investment to
achieve these purposes. The scheme is administered by the Essential Services Commission
of Victoria (ESCV) and is promoted as the ‗Energy Saving Incentive‘. The functions of the
ESCV under the Act are to accredit persons to create certificates; monitor and administer the
creation, registration, transfer and surrender of certificates; enforce the imposition of energy
efficiency shortfall penalties; undertake audits of the creation of certificates by accredited
persons and monitor compliance with the Act.
The Act ‗provides for the creation and acquisition of energy efficiency certificates‘ and
‗requires surrender of energy efficiency certificates‘. Victorian Energy Efficiency Certificates
(VEECs) are equal to one tonne of abated carbon dioxide equivalent (CO2-e). The certificate
is created by the consumer of electricity or gas in respect of whom a prescribed activity is
undertaken or an Accredited Person who the consumer has assigned the right to create a
certificate. A certificate must be created within 6 months after the end of the year in which the
prescribed activity has been undertaken.
A certificate must be created in an electronic form specified in the ESCV guidelines and must
include a unique identification code, the name of the consumer, the date and details of the
prescribed activity and the date on which the certificate was created. A certificate is not valid
until it has been registered by the ESCV and the relevant registration fee of $1 per VEEC has
been paid.
If the ESCV decides that a certificate is eligible for registration it creates an entry for the
certificate in the register of energy efficiency certificates and records the person who created
the certificate as the owner of the certificate.
A relevant entity is an energy retailer that purchases electricity or gas from NEMMCO or a
gas producer and on sells it to retail customers. A retailer is classified as a relevant entity if it
has 5000 or more customers in Victoria. Relevant entities can perform prescribed actions
and generate VEECs themselves or they can transfer them from accredited persons through
the Commission. While the Commission regulates and verifies transfers it does not regulate
any consideration paid for VEECs.
A relevant entity has a liability to surrender a number of VEECs each year. The number is
calculated using the greenhouse gas reduction rate for electricity (RE) and a greenhouse gas
reduction rate for gas (RG) that is provided by the VEET Act. To determine their VEET
liability relevant entities determine their total electricity and or gas acquisitions for the year
and multiply it by the relevant RE or RG. Relevant entities must surrender Victorian energy
efficiency certificates (VEECs) to the Commission annually between 1 January and 30 April
for the previous calendar year in proportion to their energy purchases. Where a relevant
entity surrenders insufficient VEECs to meet its liability the Commission may issue an energy
efficiency shortfall penalty. The shortfall penalty rate for 2009 is $40.
An accredited person is an individual or organisation who is able to create eligible Victorian
energy efficiency certificates (VEECs) through the undertaking of the prescribed activities
listed. At the time of the activity the consumer assigns their right to create VEECs to the
accredited person.
Page 56
An accredited person must ensure that prescribed activities are undertaken in accordance
with the requirements of the ESI scheme and that the VEECs created are in accordance with
the VEET legislation. They must also explain to consumers the implications of assigning their
right to create VEECs, collect and retain all necessary information to support their VEEC
claims.
Any person or organisation can apply to be an accredited person under the scheme.
Examples of typical accredited persons are appliance retailers and installers or energy
service providers. To become an accredited person, the person or organisation must submit
an application with the Commission together with an accreditation fee of $500. Successful
applicants are listed in the Commission‘s register published on the website. Accredited
persons are also subject to periodic audits by the Commission to provide assurance that
VEECs have been created in accordance with the VEET legislation and all obligations have
been met.
An activity can be designated a prescribed activity if the activity will result in a reduction in
greenhouse gas emissions that would not otherwise have occurred through modifying or
replacing an appliance or any equipment to reduce consumption of electricity or gas, emit
relatively lower
The Commission maintains a Register of products that are eligible for the ESI including such
as water and space heating products, thermally efficient windows and high efficiency
refrigerators and freezers. To claim VEECs for the installation of a product it must be listed in
the ESCV register. Accredited persons are required to apply to the Commission for approval
before installing insulation products, window retrofit products, weather sealing products,
lighting products or low flow shower roses to generate VEECs.
In the first phase of the VEET scheme, running from 1 January 2009 to 31 December 2011,
there are six activities that are ‗prescribed‘, that is; they are recognised as suitable measures
for meeting the VEET target. They include:
1. Replacement of low efficiency water heaters with high efficiency models
2. Replacement of low efficiency ducted heating with high efficiency products
3. Installation of insulation, window seals and energy-saving windows
4. Replacement of low efficiency lighting with high efficiency products
5. Upgrades to low-flow shower roses
6. Purchase of high efficiency refrigerators and/or destruction of pre-1996 models
The monthly registration of VEECs has appeared to have peaked in October 2009, although
‗spikes‘ of activity can be observed in June, September, December and March, probably
correlated with lodgement dates for quarterly business activity statements (Figure 12). The
scheme is well on-track to meet the 2011 target (Figure 13).

C.4.2. Advanced metering infrastructure rollout
Victoria is staging a rollout of Advanced Metering Infrastructure (AMI), which includes interval
meters that are capable of providing real-time electricity demand data to consumers and
providers (ESC, 2008). In July 2004, the ESCV directed that manually-read interval electricity
meters should be installed across the state. In 2005 a DOI and energy industry cost-benefit
study considered the addition of two-way communications and other functionalities to the
ESCV-mandated interval meters. As a result of this analysis the state government decided
that these smart meters would be installed in all residential and small business premises
over four years, starting in 2009 (Victorian Auditor-General, 2009). In April 2007 COAG,
through the MCE, committed to a national roll-out of electricity smart meters and national
cost-benefit report was released in mid-2008 (Victorian Auditor-General, 2009). The Victorian
Government had committed to rolling out smart meters prior to the national cost-benefit study
(Johnston, 2010) and despite COAG‘s commitment to the development of a national smart
meter regulatory framework, other jurisdictions have been more cautious than Victoria with
its implementation (Victorian Auditor-General, 2009). In March 2010, the Victorian Energy
Minister announced a moratorium on the introduction of time-variable pricing, although the
smart meter rollout was to continue as planned. The moratorium was based on equity
concerns that the introduction of time-variable pricing and the rollout of smart meters could
financially disadvantage low-income households who would bear costs for the rollout of
smart meters that are disproportionately high relative to their energy use and also through
facing higher prices under time-variable pricing.
C.4.3. Victorian Climate Change White Paper
The Victorian Government‘s recently released White Paper features several strategies to
improve energy efficiency in Victoria. For households, the Government aims to improve the
energy efficiency of Victoria‘s existing housing stock to an average 5 Star equivalent energy
rating by 2020 through programs such as doubling the target of the Victorian Energy Saver
Incentive and expanding the list of eligible energy efficiency activities, the delivery of a retrofit
program for energy efficiency upgrades, including support for low-income households and
the launch a new website to give households detailed information on opportunities to save
energy and obtain Government rebates. The Energy Saver Incentive will also be expanded
to allow small businesses to participate. The White Paper also includes a state-wide
behaviour change program that will build on the ‗Black Balloons‘ campaign. The behaviour
change campaign will encourage individuals to adopt a personal energy savings target,
similar to the Target 155 water campaign.
C.4.4. Emissions trading
The Carbon Pollution Reduction Scheme (CPRS) was the Australian Federal Government‘s
proposed strategy to reduce greenhouse gas emissions through economic reform. The
CPRS was to introduce a cost on carbon, which is targeted at industries that produce the
largest proportion of Australia‘s greenhouse gas emissions, in order to reduce the nation‘s
emissions overall. The CPRS Bill was withdrawn and will not be enacted until 2013 at the
earliest (Arup, 2010).
The proposed CPRS was to cover approximately 75 percent of Australia‘s emissions. The
accounting framework was congruent with the Kyoto Protocol to the United Nations
Framework Convention on Climate Change, which details the emission sources and sinks,
including four gases: carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), sulfur
hexafluoride (SF6); and two classes of gases: hydrofluorocarbons (HFCs) and
perfluorocarbons (PFCs) (DCC, 2008). These are quantified based on their global warming
Page 59
potential, as some gases produce a stronger greenhouse effect, expressed as carbon
dioxide equivalents (CO2-e). Carbon dioxide has a global warming potential of 1 CO2-e,
whereas methane has a potential of 21 CO2-e and SF6 has a potential of 23,900 CO2-e.
The government proposed a medium-term target of emission reductions of at least 5 percent
below 2000 levels by 2020 (DCC, 2008). The CPRS was to utilise a permit system, where
emitters would have been required to purchase one permit for every tonne of CO2-e that they
produced annually. Emitters that produce more than 25,000 tonnes or more of CO2-e would
have had obligations under the CRPS.
The amount of permits released would have been defined by the cap on emissions that
formed part of the trajectory to the emission reductions, with the caps specified by the
government at least five years in advance, extended one year at a time. Permits were to be
auctioned; however, some were to be administratively allocated to emissions-intensive trade-
exposed (EITE) industries during a ‗transitional phase‘, eventually moving to 100 percent
auctioning.
Sources of emissions to have been included under the scheme were those that produce
‗scope 1‘ emissions; that is, direct emissions of greenhouse gases. For example, the direct
combustion of fossil fuels within the ‗boundary‘ of a ‗facility‘ is a scope 1 emission. Indirect
emissions, which were not to be included in the CPRS, are those caused by one
organisation, but generated from a source controlled by another company; also referred to as
‗scope 2‘ emissions. For example, car tail-pipe emissions, which are covered under
obligations by the fuel supply industry, or purchased electricity, which is covered under
obligations by the power supply industry. Scope 3 emissions, not to be included under the
CPRS, include any other indirect emissions from external sources. For example, the
printing/copier paper that a company purchases has a carbon footprint associated with it, but
is not directly attributed to the company‘s use of paper.
Fugitive emissions are released during the transport and processing of fossil fuels, as well as
from methane from coal beds. Waste emissions arise from solid-waste landfill sites, water
waste and incineration of hazardous wastes. These are mostly in the form of methane
releases from decaying plant and food matter in solid-waste landfills, which account for
approximately 80 percent of emissions in this category (DCC, 2008).
The scheme was to provide substantial assistance to households, businesses and polluting
industries in the form of tax incentives and free permits. In the transport sector, this was to
include a three-year fuel-tax reduction, where for every price increase in fuel due to the
CPRS, the government would have reduced fuel-tax on a cent-by-cent basis
Initially, EITE industries were to receive assistance in the form of an ‗administrative
allocation‘ of free permits. 8 Although the rate of assistance was set to decline at an annual
rate, the free permits allocated to EITE industries would have actually increased over the first
ten years of the CPRS. In addition, ―strongly affected industries‖ were also to receive
support, despite not being trade-exposed. The only ―strongly affected industry‖ is the coal-
fired electricity generators, who were to receive a lump-sum of around $3.9 billion from the
government prior to commencement of the CPRS in order to maintain energy security.
8 Eligibility extends to EITE industries with at least 2000 t CO2-e per million dollars of revenue receive
90 percent assistance; those with at least 1000 t CO2-e per million dollars of revenue receive 60
percent assistance; or other qualifying routes outlined in the CPRS White Paper.

C.4.5. National Strategy on Energy Efficiency
The National Strategy on Energy Efficiency was developed by COAG to encourage action on
energy efficiency through addressing barriers, improving regulation, promoting technologies
and providing households and businesses with incentives, information and skills. The
strategy aims to prepare the community for a low carbon economy and the expected
introduction of the Carbon Pollution Reduction Scheme (COAG, 2009).
For industry and business this includes assisting businesses in making informed choices that
improve efficiency through addressing barriers to action, providing businesses with the
knowledge, skills and capacity needed for a low carbon economy and encouraging the
uptake of distributed generation. Industry is also targeted through the aim of providing skills
and training for the transition to a low carbon economy through the development of the
National Energy Efficiency Skills Initiative (NEESI) and specifically strengthening national
capability in energy auditing and assessment. The strategy also aims to improve the
availability of consistent date on energy efficiency and consumption for sectors such as
commercial buildings to improve policy, reporting and benchmarking. For consumers the
strategy aims to provide advice and education to ensure access to clear and consistent
information on products and services that can improve efficiency and through means such as
nationally consistent communication campaigns and the promotion of technologies and
measures (COAG, 2009).
The second theme addresses barriers in three areas. The first is electricity markets where
the focus is on encouraging the use of demand side measures such as peak load shifting
and cost-reflective pricing and also the use of distributed generation. The second area is
appliances and equipment where the strategy will establish national legislation to expand the
current Minimum Energy Performance Standards (MEPS) and labelling program and also
introduce Greenhouse and Energy Minimum Standards (GEMS). Other specific measures
are the phase-out of lighting products like incandescent globes and also the phase-out of
inefficient hot water systems. The third is transport where the strategy includes measures to
improve the fuel efficiency of cars on the road and also to encourage local manufacturers to
develop more efficient cars (COAG, 2009).
The strategy aims for a consistent national standard and performance assessment that will
drive improvements in the energy efficiency of both commercial and residential buildings. For
commercial buildings this includes increasing the stringency of energy efficiency provisions in
the Building Code of Australia (BCA) and also introducing mandatory disclosure of efficiency
for buildings. For residential buildings energy efficiency standards will be upgraded and also
broadened to include hot water systems and lighting, disclosure of energy, greenhouse and
water performance at the time of sale or lease will be introduced and owners will be
encouraged to perform efficiency improvements through information provision and incentives
(COAG, 2009).
Government will be targeted for energy efficiency improvements as significant users of
energy and also to demonstrate leadership in the community. Aims include improving the
performance of government buildings, reducing travel through the use of electronic
communication, encouraging sustainable procurement practices within government and also
increasing the efficiency of street lighting (COAG, 2009).
C.4.6. The National Framework for Energy Efficiency (NFEE)
The National Framework for Energy Efficiency (NFEE) by the Ministerial Council on Energy
(MCE) aims to enhance energy efficiency and increase the uptake of energy efficient
Page 61
technologies and practises in Australia. The NFEE includes a variety of demand-side policy
measures that target the barriers and challenges to energy efficiency achieving its economic
potential. Stage one of the NFEE commenced in August 2004 with foundation policies that
would extend or develop pre-existing state and national policies through encouraging
national coordination (Ministerial Council on Energy). There are nine policy packages that
cover:
Residential buildings
Commercial buildings
Commercial/industrial energy efficiency
Government energy efficiency
Appliance & equipment energy efficiency
Trade and professional training & accreditation
Commercial/industrial sector capacity building
General consumer awareness
Finance sector awareness
Implementation Committees or working groups deliver the Stage One plans. The groups are:
Appliances and Equipment, Buildings, Commercial and Industrial, Consumer Information,
Energy Efficiency Data Gathering and Analysis Project, Government Leadership through
Green Leases, HVAC High Efficiency Systems Strategy, National Hot Water Strategy,
Phase-out of Inefficient Lighting and Trade and Professional Training and Accreditation
(Ministerial Council on Energy).
In December 2007 Stage two of the NFEE was agreed upon by the MCE. It adds the
following five measures:
Expending and enhancing the Minimum Energy Performance Standards (MEPS)
program
Heating, ventilation and air conditioning (HVAC) high efficiency systems strategy
Phase-out of inefficient incandescent lighting
Government leadership though green leases
Development of measures for a national hot water strategy, for later consideration.
Measures developed during Stage One that are still running include the Energy Efficiency
Opportunities (EEO) program, the Energy Efficiency Exchange (EEX), and the National
House Energy Rating Scheme (NatHERS). Further measures that were introduced include
provision of energy use benchmarks on energy bills and mandatory disclosure of energy
performance of residential and commercial buildings (Ministerial Council on Energy).
C.4.7. Energy Efficient Homes Package
The $4 billion Energy Efficient Homes Package was part of the government‘s economic
stimulus package introduced in 2009 to encourage the installation of ceiling insulation and
solar hot water systems in homes. There were three elements to the package: A rebate of up
to $1,600 for home owner/occupiers to install ceiling insulation, up to $1,000 for landlords or
tenants to install ceiling insulation in rental properties and a $1,600 rebate for the
replacement of electric storage hot water systems with solar or heat pump hot water systems
(Australian Government, 2009).
Page 62
In February 2010, the measures under the package were discontinued and replaced by the
Renewable Energy Bonus Scheme, which provided the same incentives but with changes to
the delivery such as a strengthened compliance regime and a new registration scheme for
installers to prove that training and skills requirements had been met. For householders the
biggest change was to be that they would claim the insulation rebate directly through the
Medicare system instead of installers claiming it (Minister for the Environment Heritage and
the Arts, 2010). The insulation component of the Renewable Energy Bonus scheme was
supposed to begin by 1 June 2010 but following the review of the home insulation scheme by
Dr Allan Hawke, the government decided not to proceed with the insulation component
(Minister Assisting the Minister for Climate Change and Energy Efficiency, 2010). In the
windup of the insulation program the government‘s priority is on ensuring the safety of
households that have had insulation installed and have set up a safety program to inspect
homes with non-foil insulation and in homes with foil insulation either have it removed or on
the advice of a licensed electrician, having safety switches installed (Minister Assisting the
Minister for Climate Change and Energy Efficiency, 2010).
The Renewable Energy Bonus Scheme will continue with a solar hot water rebate for
homeowners, landlords and tenants replacing electric storage hot water systems with solar
or heat pump hot water systems with rebates of $1,000 for a solar hot water system or $600
for a heat pump hot water system (Minister for the Environment Heritage and the Arts, 2010).
C.4.8. Green Loans Program (Green Start)
The Green Loans Program was originally launched in 2009 with three components: free
home sustainability assessments for eligible households, a $50 reward card for participants
and access to an interest free loan for implementing sustainable measures in the home
(Minister for Climate Change Energy Efficiency and Water, 2010d).
The assessment involved a visit from a registered assessor who would consider the major
energy and water systems in the home and provide a tailored report recommending energy
and water saving changes (DCCEE, 2010c). This could include small actions like switching
light bulbs and replacing shower heads and also larger projects like solar hot water or a grey
water systems (DCCEE, 2010a).
In February 2010 that program was amended based on the first six months of operation and
responsibility for it was shifted from the DEWHA to DCCEE. The major change to the
program was that the loan component was discontinued and funds allocated for that purpose
were put towards the provision of an extra 600,000 assessments (Minister for Climate
Change Energy Efficiency and Water, 2010d). The changes were made to address identified
flaws in the process of assessors submitting reports and delays in the receipt of reports by
householders. The low uptake of loans was blamed for the cancellation of that part of the
program (Minister for Climate Change Energy Efficiency and Water, 2010d). Other changes
to address issues with assessors were an increase in the number of assessors registered to
5,000 and a weekly cap on total and individual assessor bookings (Minister for the
Environment Heritage and the Arts, 2010).
In July 2010 the Minister for Climate Change and Energy Efficiency announced that the
Green Loans program would be phased out and replaced with a new Green Start program
that will be delivered through a system of grants instead of through demand-driven loans.
The first round of grants will be awarded to accredited assessors, who will compete for funds,
to deliver energy assessments to households. The second round is for community NGOs and
other organisations to run programs that provide practical help to low-income and
disadvantaged Australians to improve their energy efficiency. Applications for funding under
Page 63
both of these rounds will open later in 2010. The changes are in response to the reviews of
the Green Loans program that identified flaws in the way the program was initially run
(Minister for Climate Change Energy Efficiency and Water, 2010c).
C.4.9. Australian Carbon Trust
The Australian Carbon Trust comprises two elements, the Energy Efficiency Trust and the
Energy Efficiency Savings Pledge Fund (Minister for Climate Change & Water, 2009). The
Australian Carbon Trust will be developed in collaboration with the Carbon Trust in the
United Kingdom which has run similar programs (Minister for Climate Change & Water,
2009).
The Energy Efficiency Trust which will provide information and tools for businesses to
increase awareness of the benefits of energy efficiency. It aims to showcase commercially
viable opportunities for efficiency and make innovative products and mechanisms
mainstream for use in commercial buildings and operations (DCCEE, 2010b). The
Government was to provide $50 million in seed funding for the Energy Efficiency Trust and
this has been increased to $100 million (DCCEE, 2010b). The Trust will operate by
identifying and proposing cost effective energy efficiency measures to businesses. The
capital costs of the measure would be funded by the trust which the business would then
repay, at a commercial rate, as they reap the energy cost savings benefits from the measure
(Minister for Climate Change & Water, 2009). This approach addresses the barrier of capital
investment for businesses investing in energy efficiency and also demonstrates the
profitability of efficiency to the commercial sector (Minister for Climate Change & Water,
2009).
The Energy Efficiency Savings Pledge Fund is targeted at householders. A website will
provide householders with tools to calculate energy use and also identify ways to become
more efficient. Based on their savings they can then make donations towards the Pledge
Fund which will go towards the purchase and retirement of Australian Emissions Units under
the CPRS or approved offsets (Minister for Climate Change Energy Efficiency and Water,
2010b). Pledges made will be pooled across individuals and households, are voluntary and
will be tax deductible (Minister for Climate Change & Water, 2009).
As of May 2010 the Australian Carbon Trust is still in the process of being setup with
management being appointed and programs being transferred from the government
(Herbert, 2010). The future of the Pledge Fund is unclear given the postponement of the
CPRS and it no longer features on the Carbon Trust‘s website (DCCEE, 2010b). In July 2010
the Minister announced that the Australian Carbon Trust will also administer a new Carbon
Neutral Program, an initiative of the National Carbon Offset Standard (NCOS), which
commenced on 1 July 2010, and which aims to provide national consistency in the voluntary
carbon market. This replaces the carbon neutral component of the Greenhouse Friendly
program, which ended on 30 June 2010. The Carbon Neutral Program will allow businesses
to certify their products, services or operations as carbon neutral by applying to the Carbon
Trust for use of the NCOS logo (Minister for Climate Change Energy Efficiency and Water,
2010a).
C.4.10. COAG Agreements
COAG agreed to develop a ‗National Strategy on Energy Efficiency‘ in October 2008. A
Memorandum of Understanding (MoU) was agreed to by COAG on 30 April 2009 relating to
the ‗National Strategy on Energy Efficiency‘, which was to run from 2009-2020.
Page 64
The most recent agreement between the Commonwealth, State and Territory Governments
was signed in July 2009 and sets out a ‗National Partnership Agreement on Energy
Efficiency‘, which gave effect to the ‗National Strategy on Energy Efficiency‘ previously
agreed to under the MoU. The agreement recognises that even with a price on carbon, as
provided by the Carbon Pollution Reduction Scheme (CPRS), investment in many of the
cost-effective energy efficiency opportunities will not occur because of market impediments.
The National Strategy seeks to provide an approach to overcome these barriers.
The Total Environment Centre (TEC) identified that while demand management has been
supported strongly by COAG, it continues to be neglected by the National Electricity Rules
that govern the national market (TEC, 2007).

C.5. Institutional barriers
C.5.1. Market failures limiting energy efficiency investment
The following markets failures that act as barriers to investment in cost-effective energy
efficiency opportunities have been identified (MMA, 2008, The Climate Institute, 2008, Vine
et al., 2003).
C.5.1.1. Information failures
A general lack of information availability regarding the energy efficiency of products and
buildings can cause missed energy efficiency opportunities. This can be reduced through
energy rating and labelling of appliances and mandatory efficiency standards for new
buildings and renovations.
C.5.1.2. Split incentives (or incentive misalignments)
Cost-effective energy efficiency opportunities exist where the person making the investment,
the most commonly cited example being landlords of rental accommodation, does not
directly experience the benefits of their investment.
C.5.1.3. Capital constraints
The up-front cost of energy efficiency opportunities can be a barrier to investment, even
though the long-term cost savings more than make up for the initial investment. This barrier
can be overcome, to some degree, by no-interest loan schemes.
C.5.1.4. Jevons Paradox
In modelling studies, a ‗rebound effect‘ occurs, known as the Jevons Paradox, where
increasing energy efficiency stimulates other parts of an economy, thereby increasing overall
emissions (Foran, 2009).
C.5.1.5. Behavioural barriers
Cost-effective energy efficiency opportunities may be passed up by consumers as other
factors may be more important in choosing products. Consumers do not behave as rational
economic agents and might not be motivated to pursue all cost-effective energy efficiency
opportunities.
C.5.2. Barriers to installation of energy-saving devices in households
Householders are not always capable of adapting energy-conserving devices if psychological
and positional barriers are insurmountable (Costanzo et al., 1986). Psychological barriers
include the degree to which a householder perceives, understands and favours a particular
conservation measure, and their motivation in remembering and pursuing the measure
(Costanzo et al., 1986). Attitudes, values and beliefs also play a role, as do contextual
forces, such as institutional factors (Whitmarsh, 2009). Positional barriers include
permissions (e.g. rental tenants are not always permitted to make modifications), price of
purchase and/or installation, ability to install one‘s own devices and their compatibility with
existing fittings.
Page 66
C.6. Conclusions
A review of regulations, organisations and stakeholders in the ‗Victorian electricity managing
system‘ revealed a high degree of institutional complexity. This is partly due to the
disaggregation of electricity industry, previously integrated under one state-owned utility, and
also the formation of the National Electricity Market and the regulations and organisations to
manage it. The interplay between Federal and State organisations and schemes can also be
seen as adding to this complexity. It can be concluded that in accomplishing the goals of
reducing electricity use and transitioning to a post-carbon society, the solution cannot merely
be to establish new or more institutions and schemes that will find themselves negated by
existing institutions.
Compared to California, where regulation and efficiency standards have successfully
reduced per capita electricity demand, local contextual factors in Victoria continue to act as a
barrier to the uptake of demand management. In California, the strength of the regulator and
the influence of the Clean Air Act provided the impetus for innovative actions. In both
California and the United Kingdom, the ‗landscape‘ has shifted from a focus on deregulation
and the efficient operation of the market to an increasing awareness of environmental and
sustainability concerns within the context of a response to climate change.
A lack of political vision on the need for a comprehensive response to climate change fails to
recognise the need to establish a transition pathway to a post-carbon society. This goal is not
currently reflected in the structure and aims of the institutional actors that control the national
electricity system. The strategic purpose of both the Australian Energy Market Commission
and the Australian Energy Regulator are derived from the doctrine that led to market
deregulation, which was enacted for reasons of market efficiency, not energy efficiency. The
expectation that market mechanisms alone will be able to reduce electricity use will lead to
systemic failure. The current electricity managing system is not fit for the purpose of dealing
with climate change by reducing electricity use.
The postponement of an emissions trading scheme, which was expected to drive a reduction
in greenhouse gas emissions, has meant that Victoria is left with a piecemeal approach,
comprised of isolated programs at State and Federal level that look to overcome barriers and
market failures. This has lead to problems of inconsistency and mixed messages from
different institutions and information overload. However, out of this complexity, the Victorian
Energy Efficiency Target (VEET) scheme provides an effective and long-term model for a
broader and more consistent approach that addresses some of the institutional barriers to
reducing electricity use.
Addressing energy use and efficiency through demand management is part of three pronged
approach to transitioning to a post-carbon society. This includes developing renewable
energy technology to lower the carbon intensity of electricity, implementing greater
systematic energy efficiency through technological innovation and addressing end-use
efficiency more systemically.
