Investing in Renewable Energy/ Energy Efficient Equipment ?
What are the factors that determine the cost-effectiveness of the additional investment?
Parameters affecting Decision
Amount of Investment
Amount of Energy Saving (fossil fuel)
Price of Energy
Life of Equipment/ project
Time Value of Money
Renewables – usually higher initial cost,
lower operating cost

Economic Criteria
Simple Payback Period (SPP)
Net Present Value (NPV)
Benefit/ Cost Ratio (B/C)
Internal Rate of Return (IRR)
Life Cycle Costing
Life Cycle Cost
Annualised Life Cycle Cost (ALCC)
Simple Payback Period
No of years in which investment pays for itself
SPP = Initial Investment/ Annual Saving
Limitations?
A Inv Rs 100,000 , Saving Rs 50000
B Inv Rs 120,000, Saving Rs 40,000
Decision?
Discount Rate
Compare investment today with expected future benefits
Discount rate represents how money today is worth more than in the future
No theoretically correct value
Lower bound – bank interest rate
Annualised Life Cycle Cost
Annualised Life Cycle Costs (ALCC) -annual cost of owning and operating equipment
ALCC = C0 CRF(d,n) + AC f + AC O&M
CRF (d,n) =[ d(1+d)n]/[(1+d)n-1]
discount rate d, Life n years, C0 Capital Cost,AC f , AC O&M , annual cost - fuel and O&M CRF – Capital recovery factor

• Energy Access• Renewable Energy• Energy Efficiency• Nuclear Energy• Pricing/ Taxes/Subsidies
INDC
Reduce Carbon Intensity of GDP by 33-35% of 2005 level in 2030
Create 40% cumulative non fossil power by installed capacity by 2030 (using finance from Green Climate Fund)
create an additional carbon sink of 2.5 to 3
billion tonnes of CO2 equivalent through additional tree cover and forest

Cost of Electricity Generation
Capital cost Rs/kW
Selco Case study For profit company – Solar Home
systems – started 1996 – sold about 100,000 SHS
90% of products – credit schemes
Partnership with 9 banks – interest rates between 12-17%
Financing Institutions pay 85% of the amount- monthly payments of Rs 300- 400 over a period of 5 years
Financing/ repayment options –tailormade to end users – paddy farmers – repayment schedule based on crop cycle, street vendors – daily payments – Rs 10
Funding from REEP – meet margin amount for poor customers, reduce interest rate 41

DESI Power
Biomass based power solutions – Bihar- 25 kW to 100 kW
Local distributors – decide pricing
Registered under CDM and sold CERs to Swiss buyer
MNRE funds, Promoters Equity, ICICI Loan
Monthly rate based on no of bulbs / loads, Circuit breaker to limit consumption
Irrigation pump users Rs 50/ hour, Household Rs 120- 150 per month
Underground trunk wiring-distribution
Enabling micro-enterprises –battery charging station, flour mill, workshop etc
Tie up with Telecom towers – increasing capacity factor
42
Husk Power
Initial funding – prize money 30-100 kW – biomass gasifiers- based on
rice husk Energy audit of households Focus on household demand for lighting Lower production, operating costs – use of
bamboo, asbestos Overhead pole wiring Directly reach end user
43
Nuclear Liability
Civil Liability for Nuclear Damage Act –Operator Liability Limit Rs 1500 crores
“The operator shall have a right of recourse where-the nuclear incident has resulted is a consequence of an act of supplier or his employee, which includes supply of equipment or material with patent or latent defects or sub-standard services.”
50
Indo-US Deal (Jan 2015)
Nuclear Liability Fund – Insurance cover of Rs 1500 crores
Insurance premium from electricity supply price
51
New Nuclear Power Plants
Kudankulam, Tamil Nadu – VVERs –Russia – 2X1000 MW- Rs 17320 crores
Jaitapur 9900 MW (6*1600 MW) –Ratnagiri district – French – AREVA 9.3 Billion US $

Not feasible to define a single norm/standard unless there is significant homogeneity amongst units in a sector
Energy efficiency improvement targets would have to be almost“unit specific”
Bands of differential targets to be created within sectors
Each DC mandated to reduce its SEC by a fixed percentage, based on its current SEC within the sectoral bandwidth
Setting Energy Consumption Norms
Source: DG BEE presentation
Huge spread in Specific Energy Consumption within sectors
Target is Plant Specific …… Less for Energy Efficient and more for Inefficient Plants

Data Requirements and Verification
Verification to be carried out by independent BEE-designated energy auditors (DENAs)
SEC for a plant is based on the records of quantum of energy going into the plant and quantity of products shipped out of plant
Cross check with records such as invoices, payment receipts, and excise paid
Inplant renewable energy production would not be added to quantum of energy used
Normalization factors for large changes (during the 3-year period) in:
Share of captive electricity generation
Capacity utilization
Raw material quality/Product Mix
Source: DG BEE presentation
PAT – progress
SEC reduction targets notified for 478 units in 8 energy intensive sectors notified as Designated Consumers under EC Act. They sectors are: Aluminum, Cement, Iron & Steel, Chlor Alkali, Thermal Power Plants, Fertilizer, Pulp & Paper, and Textiles
Targets to be accomplished in 2014-15
Normalization formulae notified in December 2013
