Energy efficiency pays !

A third-party (called an “Energy Service Company”, or ESCo) was awarded a “performance contract” to achieve the savings• ESCo invested in energy efficiency improvements• Is paid a 25% share of the annual savings (beyond the

baseline) for a five-year period• Is paid 50% of savings in excess of 9.55 lakh kWh

Savings have been in the 10-11 lakh kWh per year range

Energy efficiency opportunities in Rashtrapati Bhawan were assessed to save 9.33 lakh kWh/year – about one-fifth of the annual consumption

Large potential exists in the Estate

Rashtrapati Bhawan Estate has offices, residences, stables, substation and water-pumping station

Large potential for energy savings exists• Savings in some of the

identified end-uses would result in 40-80% savings

• Some of the identified interventions have already been implemented as part of Roshni

New initiative to change ceremonial lighting to LEDs

There are large opportunities for energy efficiency in new buildings

The Centre for Environmental Science & Engineering (CESE) at IIT, Kanpur has been designed as an energy-efficient building• Complies with the Energy

Conservation Building Code (ECBC) of the BEE, and is a GRIHA-4 star building

• Has both air-conditioned and non-conditioned areas

• Energy consumption is 40% of that of the original design

All ECBC-compliant buildings use at least 50% less energy

Energy Efficiency – the larger context

Energy efficiency makes economic sense – and is happening

Yet, there are unexploited opportunities – due to market failures• Lack of information about energy

performance• Higher cost of an energy-efficient

option• Perceived risk of new technologies• Split Incentives – especially in

buildings

Energy Conservation Act provides for:• Standards and labeling for appliances• Energy Conservation Building Code• Energy consumption norms for

energy-intensive industries

Incentivising energy efficiency in industry

A wide bandwidth of energy efficienciesoccurs in almost all industry sectors• Difficult to specify a single sectoral

energy consumption norm

“Perform, Achieve & Trade” mechanism introduced for 580 industrial units whichhave to meet SEC reduction targets• Covers units using about 180 million toe/year; national use is

400 million toe/yr• Gate-to-gate specific energy consumption, collectively, to be

about 5% less in 2013-14 than it was in 2008-09 • Less efficient units have larger SEC %-reduction targets – so

that the collective SEC reduction is 5%

Energy Savings Certificates (and penalties) would be based on difference between the achieved SEC and the target SEC• Trading of savings enables flexibility and cost effectiveness

Other Initiatives

Bachat Lamp Yojana - Promotion of CFLs in households• Facilitates firms in providing CFLs to households at price of

incandescent bulbs• Cost difference recovered through carbon credits because

of their lower energy use • CDM Programme of Activities enables quick registration of

many small projects• 20 million have already been replaced

Using performance contracting to enhance energy efficiency in• Municipal streetlighting & water pumping

• Agricultural water pumping

Promotion of energy efficiency in SMEs
