Demand Side Management and energy efficiency initiatives at TPDDL are aimed at bridging the demand-supply gap and promoting energy security and climate change mitigation. TPDDL's load curve analysis shows peak demand is higher in summers compared to winters. Domestic consumers account for around 44% of energy consumption. Past initiatives included distribution of CFLs and promoting star-rated appliances. The 2015 DSM Based Efficient Lighting programme will provide consumers LED bulbs at subsidized rates to promote energy efficiency.

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
12. 2012 Bachat 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
13. 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

2012 Promotion of Star Rated Appliances
14. 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
15. 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

2013 Appliance Replacement Programme
16. 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)

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 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.
