India - lighting energy efficiency savings

By replacing incandescent and CFL bulbs with LEDs, in Puducherry and Andhra Pradesh, a government program has resulted in:
A staggering 68 lakh kilowatts of energy is saved every day. This includes a cut in 645 megawatts of power during peak hours, a 5,520-tonne drop in daily carbon emission and domestic savings of Rs 2.71 crore every day.
How?
The LED project is financed by consumers themselves through two plans. The first one is an 'onbill EMI' model under which consumers have to pay Rs 105 for an LED bulb across 10 months, which is added to the monthly power bill. The second plan allows the consumer to buy bulbs in one go — every consumer is entitled to four LED bulbs — by paying Rs 100 apiece. (The bulbs come with a three-year replacement warranty.)

LED bulbs actually cost Rs 300-350 apiece in the market — the government offers cheaper bulbs because it procures in bulk, around 7.5 crore bulbs so far. The government effort has already halved market prices from Rs 650-700 apiece a year ago.

For the project, LED lamps are procured at Rs 78 apiece. The additional Rs 27 that consumers must pay are due to the interest charges on financing, database maintenance and distribution cost.
