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 & EE INITIATIVES

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

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

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

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

consumer sensitization about the BEE Star
Rated ACs & Refrigerators
15
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)

(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.
