Load Research
•
Load research carried out for residential consumers
(10,000) in 2010
•
Objective: To understand the end energy use &
penetration of various brands, appliances among
consumers
•
Based on the findings, identified following DSM program
: Policy advocacy of Gas water Heaters
 Appliance Replacement Program for Refrigerators &
Air Conditioners
 Awareness on star rated appliances

DJB Peak Shifting
•
First of its kind peak shifting project in consortium with
water utility of Delhi, Delhi Jal Board (DJB).
•
After load profiling of TPDDL & DJB, suggested DJB to
shift its morning operating hours (water pumping
stations) by 1.5 hours, to minimize coincidence with
TPDDL peak
•
Shift in the operation time was initiated from Aug ’09.
•
Continuous monitoring & verification in progress.
•
Key Benefits:
 Shift of 2 MW load from TPDDL peak

(MoEF) ;resulted in MOEF issuing guidelines to all the major
banks in Delhi to ensure the optimal temperature setting of
the ACs of their ATMs
•
Observed savings of 0.16 MUs during summer
•
Regular Monitoring &Verification in progress

•
TPDDL in association with BEE and ICF (consultant)
developed
an Appliance Replacement program for
Refrigerators and Air conditioners
DFID (A UK grant agency) agreed to fund the expenses for
Market Research, Stakeholder Workshops and Final report,
for replication across India.
Expected to be launched in March ‘12.
Under the scheme, star rated refrigerators and ACs would be
