1. Introduction As part of the ongoing process of strengthening the Victorian Energy Efficiency Target (VEET) scheme, the Victorian Government is seeking your input on a number of changes to the VEET Regulations 2008. These changes aim to improve access to existing energy saving activities and to ensure that all activities are correctly rewarded. Activities have been targeted because they are: • Activities that have had little uptake to date, and have an obvious barrier to uptake. For

these activities, a limiting barrier is being removed. • Activities that have undergone significant market or technological change. For these

activities, the baseline is being updated.

The VEET scheme is a baseline and credit scheme. Credit is awarded in the form of certificates when activities are undertaken that reduce energy consumption more than would be achieved under business as usual conditions (the baseline). As the market and technologies change, including changes in the stringency of minimum energy performance standards (MEPS), the baseline needs to be adjusted to ensure that activities are being correctly rewarded. We will consider your feedback on these changes before any Regulation amendments are made. We intend to make these proposed regulatory amendments ahead of adding any new VEET activities. We currently have a separate consultation process underway on introducing project-based methodologies to the scheme. Please see energyandresources.vic.gov.au/esi for further information and timings.

2. Stakeholder input We are currently seeking your feedback on our proposed regulatory changes designed to continue making the VEET scheme stronger. The Victorian Government is determined that this scheme provide even greater support to delivering energy efficiency improvements for Victorians, and your feedback on how we achieve this is welcome. A summary of the changes to each activity is described below. Stakeholders should also consult the relevant sections of the proposed Regulations. These are available online at: energyandresources.vic.gov.au/esi For each activity, please provide feedback on the following questions, where relevant:

• Do you have any comment on the proposed amendments? • Is the timing of the proposed Regulation amendments appropriate? Why/why not? • Do the changes remove the appropriate barriers to uptake? Why/why not? • Are any other changes warranted? Please provide details.

Responses should clearly state the issue and, where relevant, reference specific sections of the Regulations.

3. Greenhouse gas abatement coefficients We propose to update the coefficients used in calculating the greenhouse gas abatement of each activity, so that they reflect the latest available information. Recent modelling by Jacobs Group Australia found that the marginal greenhouse gas coefficient for electricity use avoided by VEET (ex-generator) is 1.03 kg CO2-e/kWh. As this value is ex-generator, the impact of transmission and distribution losses needs to be incorporated to create an end-use abatement coefficient. (The process of transmitting and distributing electricity results in power being lost over the journey. This should be accounted for as part of the emissions reductions achieved through VEET activities). The statewide loss factor is assumed to be 1.06, leading to an overall greenhouse coefficient for electricity of 1.095 kg CO2-e/kWh. The coefficient value previously used was 0.963 kg CO2-e/kWh. As power often has to travel further to reach regional areas, losses are generally greater than in metropolitan areas. As a result, a regional loss factor is applied, with a multiplier of 1.04 for regional areas and 0.98 for metropolitan areas. The abatement value for natural gas is based on the National Greenhouse Accounts Factors December 2014, incorporating scope 1 and scope 3 emissions and is 55.23 kg CO2-e/GJ. The current abatement value for natural gas is 57.3 kg CO2-e/GJ. In the absence of any other regulatory changes, the overall impact of these changes will be that electricity savings delivered through the scheme will create slightly more certificates, while gas savings will create slightly less certificates. The recently announced VEET scheme



targets take this increase into account. The revised coefficients will be incorporated into other activities as they are updated.

4. Overview of proposed amendments

4.1. Schedules 7, 8, 9 and 10 – Space heating The primary change proposed for space heating activities (7, 8 and 10) is to remove the restriction which prevents certificates being awarded in postcodes with access to a natural gas connection. This change is proposed because high performance heat pumps now have similar greenhouse gas abatement and energy efficiency performance to high efficiency gas heaters. These heaters are increasingly being chosen by households as a main form of heating and are a viable alternative across Victoria. In addition the basis of the calculations and minimum eligibility requirements have been updated to reflect increases in the average energy efficiency of reverse-cycle air conditioners. The abatement factors and regional factors will be updated in Schedules 7, 8, 9 and 10. The regional factors take account of increased electricity distribution losses outside metropolitan Melbourne, as well as different climate types. For schedules 9 and 10 these factors also take into account the mix of existing heater types installed in regional and metropolitan areas. These proposed changes are based on the latest available information on the penetration of different heater types.

4.1.1 Schedule 7 – High Efficiency Ducted Air To Air Heat Pump Replacing A Ducted Air To Air Heat Pump

We propose increasing the minimum required performance for ducted reverse-cycle air-conditioning, given the significant increase in the market average performance since we introduced these the activities in 2008.The proposed regulations also update references to the current relevant standards. The impact of the proposed changes is that the certificate allocation is reduced. The certificate allocation is based on the difference in energy consumption between the high-efficiency unit to be installed (in defined bands) and the average efficiency of new units currently available on the market. As the average efficiency of available units has risen, the abatement achieved by replacing the average unit with a higher-efficiency unit has reduced. These changes are proposed to commence on 1 January 2016. Note that in the tables below, CoP refers to coefficient of performance, and ACOP refers to annual coefficient of performance as defined in AS3823.2:2013. Certificates for activity = Abatement Factor x Regional Factor The appropriate regional factor is determined from a postcode lookup table in the Regulations

How are certificates for this activity affected? In general, the number of certificates per air-conditioner installed will be lower because the market average performance of new ducted reverse-cycle air conditioners has improved since 2008. Example: Regional Victoria/Cold, ACOP 4.2 (CoP 4.0 to 4.9), Medium size

Previous certificates = 10.68 x 1.71 = 18.26 certificates Revised certificates = 7.51 x 1.72 = 12.9 certificates

What equipment specification changes are proposed? We propose increasing the minimum performance of installed ducted reverse cycle air-conditioner units to an ACOP of 3.7. This is expressed as an annual coefficient of performance in compliance with Minimum Energy Performance Standards (MEPS) and AS3823.2:2013



What does the gas-reticulation limitation change mean? Under the proposed changes, VEET incentives for installing ducted reverse-cycle air-conditioning will no longer be limited to areas that do not have reticulated mains gas. This activity is proposed to be eligible across Victoria.

4.1.2 Schedule 8 – High Efficiency Ducted Air To Air Heat Pump Replacing Central Electric Resistance Heater

We propose increasing the minimum required performance for ducted reverse-cycle air-conditioning, given the significant increase in the market average performance since we introduced these the activities in 2008.The proposed regulations also update references to the current relevant standards. It is proposed that the abatement calculations are updated, incorporating changed assumptions in the cooling performance of the ducted air conditioner to reflect the latest available information, adjusting the assumed cooling load to reflect a change in the understanding of the way cooling is used and also taking into account the duct losses which had previously not been taken into consideration. These changes are proposed to commence on 1 January 2016. Certificates for activity = Abatement Factor x Regional Factor The appropriate regional factor is determined from a postcode lookup table in the Regulations Table 3.

In general, the number of certificates per installation will be slightly higher because of an increase in the underlying greenhouse gas abatement factor for electricity and the net impact of the other changes made to the calculation algorithms. Changes to the regional factor will tend to make certificates lower in the Regional Victoria/Hot climate area. Example: Regional Victoria/Hot, ACOP 4.2 (CoP 4.0 to 4.9), Medium size

Previous certificates = 131.9 x 0.67 = 88.4 certificates Revised certificates = 136.0 x 0.61 = 83 certificates

What equipment specification changes are proposed?: We propose increasing the minimum performance of installed ducted reverse cycle air conditioner units to an ACOP of 3.7. ACOP is the annual coefficient of performance defined in AS3823.2:2013 What does the gas-reticulation limitation change mean? Under the proposed changes, this activity will no longer be limited to areas that do not have reticulated mains gas. This activity is proposed to be eligible across Victoria.

4.1.3 Schedule 9 – Gas or Liquefied Petroleum Gas Space Heater

It is proposed that the abatement calculations are updated to incorporate changed assumptions, based on the latest available information, about the mix of installed heating in houses in Melbourne and regional Victoria and the efficiencies of these heaters. In addition, the greenhouse coefficients have been updated. These changes are proposed to commence on 1 January 2016.



Certificates for activity = Abatement Factor x Regional Factor The appropriate regional factor is determined from a postcode lookup table in the regulations Table 5. Current certificate allocation for Schedule 9 – Gas or Liquefied Petroleum Gas Space Heater System size

Abatement Factor

4.0 to 4.9 Stars 5.0 Stars + Small (2 - 3 kW) 4.32 4.83 Medium (3.1 - 6.0 kW) 8.19 9.17 Large (> 6 kW) 10.22 11.44

Melbourne / Mild 1.00 1.00 Regional Victoria / Mild 0.22 0.29 Regional Victoria / Cold 0.36 0.46 Regional Victoria / Hot 0.15 0.20 How are certificates for this activity affected? For this activity the change in certificates generated will vary depending on where the heater is installed. In Melbourne, certificates will increase slightly, while in other areas they will fall. This reflects the higher incidence of electric heating in Melbourne compared to Regional Victoria. Example: Regional Victoria/Mild, 5 stars, Medium size

Previous certificates = 9.17 x 0.39 = 3.6 certificates Revised certificates = 10.55 x 0.29 = 3.1 certificates

What equipment specification changes are proposed? There are no proposed changes to equipment requirements.

4.1.4 Schedule 10 – Space Air to Air Heat Pump We propose increasing the minimum required performance for reverse-cycle air-conditioning, given the significant increase in the market average performance since we introduced these the activities in 2008.The proposed regulations also update references to the current relevant standards. Changes are proposed to the abatement calculations, incorporating changed assumptions in the cooling performance of air conditioners to reflect latest available information and adjusting the assumed cooling load to reflect a change in the understanding of the way cooling is used. These changes are proposed to commence on 1 January 2016. Certificates for activity = Abatement Factor x Regional Factor The appropriate regional factor is determined from a postcode lookup table in the Regulations Table 7.

In general, the number of certificates per installation will be lower for the same equipment because the market average performance of new room reverse-cycle air conditioners has increased. Example: Melbourne, ACOP 4.2 (CoP 4.0 to 4.49), Medium size

Previous certificates = 11.65 x 1.0 = 11.65 certificates Revised certificates = 8.33 x1.0 = 8.33 certificates

What equipment specification changes are proposed? The proposed changes will increase the minimum performance of reverse cycle air-conditioner units in line with greater market availability of high-performance units and increased MEPS (Minimum Energy Performance Standard) levels. The proposed minimum is an ACOP of 4.0. Performance will be expressed as annual coefficient of performance in compliance with MEPS and AS3823.2:2013. What does the gas-reticulation limitation change mean? Under the proposed changes, this activity will no longer be limited to areas that do not have reticulated mains gas. This activity is proposed to be eligible across Victoria.

4.2. Schedule 21 - Incandescent Lighting We propose several changes for this activity, to update it in line with recent improvements in lighting technology and to account for the implementation of MEPS for incandescent and extra low voltage (12 volt) lighting since the commencement of the VEET.

• Abatement factors are proposed to be revised to reflect changes in business as usual performance of the lamp being replaced. This is based on changes in the market penetration of pre- and post-MEPS lamps assumed in the calculations and an increase



11

in the assumed rate of business as usual replacement of the existing lamps with low energy lamp types.

• We propose to update the minimum performance criteria for lighting equipment so they reflect improvements in equipment lighting technology, especially LED lighting.

• Schedule 21B will be removed, lighting technology development has meant that there is no longer a need in the market for this activity.

• Schedule 21E will be introduced to allow the replacement of mains voltage halogen lamps with GU10 bases with a low energy alternative.

The regional factor and PF (Power Factor) factor for all aspects of Schedule 21 remain unchanged. As with the other revised measures the new, higher, greenhouse coefficient for electricity will be used when calculating the number of certificates allocated.

Recognising the potential lead time for procuring and testing new lamps, we propose that these amendments come into effect on 1 March 2016.

4.2.1 Schedule 21A - Installation of low energy GLS in place of mains voltage GLS

How are certificates for this activity affected? In general, this activity will create fewer certificates per installation due to changes in the certificate calculation assumptions around business as usual replacement of existing lamps and the impact of lighting MEPS. Example:

15,000 hour rated life, High Efficiency 2, Melbourne region, power factor less than 0.9 Regional factor=0.98 (Melbourne region) PF factor=1.00 (power factor less than 0.9) Previous certificates = 0.54 x 0.98 x 1.00 = 0.53 certificates Revised certificates = 0.43 x 0.98 x 1.00 = 0.42 certificates

What equipment specification changes are proposed? No equipment changes are proposed for this activity

How are certificates for this activity affected? In general, this activity will create fewer certificates per installation for the same equipment due to changes in penetration of pre and post-MEPS halogen lamps assumed in the certificate calculation and an increase in the assumed rate of business as usual replacement



of existing lamps with low energy lamp types. However, the maximum number of certificates for the highest efficiency, longest lasting lamps will increase. Example:

15,000 hour rated life, 52 lm/W, Melbourne region, power factor less than 0.9 Regional factor=0.98 (Melbourne region) PF factor=1.00 (power factor less than 0.9) Previous certificates = 0.59 x 0.98 x 1.00 = 0.58 certificates Revised certificates = 0.44 x 0.98 x 1.00 = 0.43 certificates

How are certificates for this activity impacted? In general, this activity will create fewer certificates per installation of the same equipment due to changes in penetration of pre and post-MEPS halogen lamps assumed in the certificate calculation and an increase in the assumed rate of business as usual replacement of existing lamps with low energy lamp types. Example:

15,000 hour rated life, 58 lm/W, Melbourne region, power factor less than 0.9 Previous certificates = 0.63 x 0.98 x 1.00 = 0.62 certificates Revised certificates = 0.48 x 0.98 x 1.00 = 0.47 certificates

4.3 Schedule 31 - High Efficiency Motor Replacing An Electric Motor

The primary change for this activity will be to remove the requirement to decommission and replace an existing unit. As this activity is baselined to the performance of the minimum energy performance standard (MEPS) for new motors, any installation of a complying motor under this activity will be additional abatement against business as usual conditions. In addition to this the new, higher, greenhouse coefficient for electricity will be used in the certificate calculation. These changes are proposed to commence on 1 January 2016. Certificates for activity = Abatement Factor x Regional Factor

How are certificates for this activity affected? In general, this activity will create more certificates per installation for the same equipment due to the higher greenhouse gas abatement coefficient for electricity.

What equipment specification changes are proposed? Minor equipment changes are proposed through updated references to AS 1731.14-2003 Amendment 2.

4.3 Schedule 33 - Refrigeration Fan Replacement The primary change for this activity will be removing the requirement to decommission and replace an existing refrigeration fan unit. As this activity is baselined to the performance of typical refrigeration fan units, any installation of a motor/fan under this activity will create additional abatement as compared to business as usual conditions. In addition, greenhouse abatement coefficients have been updated. Note that more complex changes to this activity will be considered in 2016. These changes are proposed to commence on 1 January 2016. Current certificate allocation (IP x 0.7692 + 19.385) x (1+ (1 / COP)) x 0.02952 x Regional factor Where

IP is the input power of the motor that powers the fan COP is the coefficient of performance of the type of refrigerator where the fan is installed from the following table Refrigerator type COP

Revised certificate allocation (IP x 0.7692 + 19.385) x (1+ (1 / COP)) x 0.03357

How are certificates for this activity affected? In general, the number of certificates per installation will be higher for the same equipment due to the increased greenhouse gas abatement coefficient for electricity What equipment specification changes are proposed? No equipment changes are proposed.

4.4 Schedule 34 - Commercial lighting The primary changes to this activity are to

• Add variable hours of use to allow for differing building operating times • Add the capability for non-building based lighting projects (eg street lighting) to

participate • Update greenhouse abatement coefficients

These changes are proposed to commence on 1 January 2016. How are certificates for this activity impacted? In general, this activity will create slightly more certificates per installation of the same equipment due to changes in the greenhouse abatement coefficient for electricity. In installations that are able to claim longer hours of use, the more certificates will be created. What equipment specification changes are proposed? We propose that the Essential Services Commission set the standards for some lighting equipment, due to the nature of emerging technologies and the lack of well-established Australian Standards in some areas.
