DSM Schemes identified based on Load Research findings

RESIDENTIAL INDUSTRIAL & COMMERCIAL

• T5 FTL programme • Partly funded energy audit programme

• AC & refrigerator replacement programme

• SME cluster based programme

• Star rated ceiling fan • Bulk procurement (lighting) programme

• LED bulb & tube light for high end consumers

• Awareness on sun reflect paints

DSM & EE INITIATIVES

2012Bachat Lamp

Yojana

Bachat Lamp Yojana (BLY) : A CDM based scheme developed by BEE; Aimed at large scale replacement of incandescent bulbs in households by CFLs

Under BLY, CFLs were offered at Rs. 15 in exchange of working ICL bulbs (for residential consumers)

Over 8 lakhs CFLs were distributed under the scheme

Annual Deemed energy saved: 47.18 MUs

12

Appliance Replacement Program was launched in association with LG, Voltas & Godrej

Offered Exchange Scheme, under which existing old Refrigerators and Air Conditioners could be replaced with new Energy Efficient BEE Star Rated Refrigerators & ACs

Consumers benefit-Reduction in energy bills, special discounts on market operating prices, good salvage value for old appliance

Over 4000 star rated Appliances were sold under the scheme

Deemed Energy saved:

• 0.72 MUs for 1000 ACs• 0.70 MUs for 1000 Refrigerators

13

2012 Promotion of Star Rated Appliances

A Pilot project was conducted on one of the TPDDL building. Decrease of 5°C in room temperature and 8% energy savings was observed

TPDDL in association with Dulux launched a discount based scheme for its sun reflect paint range (Weathershield) for TPDDL consumers and employees under which the product was offered at 20% discount through the selected dealer outlets

Over 12,600 Litres of paint was sold under the scheme

14

2013 Sun heat reflect paint

TPDDL in association with BEE and ICF (consultant) developed an Appliance Replacement program for Refrigerators and Air conditioners

Under the scheme, star rated refrigerators and

ACs were offered at the discounted rates (against the prevailing Market Operating Prices) & existing appliances were bought back for the safe disposal

2 major activities conducted under the project:-

– Conduct of focused Load survey for 1500 Residential, I& C consumers

– 12.5 lakhs Pamphlets were distributed for consumer sensitization about the BEE Star Rated ACs & Refrigerators

15

2013 Appliance Replacement Programme

TPDDL in association with 2 LED manufacturers launched a discount based scheme where 7 W LED bulbs were offered at Rs. 300 (MRP:Rs.450) with 3 years warranty

Duration of the Scheme: 3 months

Offer was made available for TPDDL consumers and employees

Over 8000 Bulbs were sold under the scheme

16

2014 LED Bulbs for TPDDL consumers

LED

17

2015 DSM Based Efficient Lighting programme (DELP)

• Under this scheme the consumer is eligible to purchase up to 2 LED bulbs at an upfront cost of Rs. 10 each. The balance amount of Rs. 120 will be recovered from the electricity bill over a period of 12 months @ Rs. 10 per month.

The consumer will get a high quality LED bulb at the price of INR 130/- as against a market price of Rs 400.

Energy Efficiency Services Limited (EESL) a public sector body of Government of India is implementing agency for the programme

The Distribution of LEDs is expected to commence on 1st March, 2015.
