Regulation shall be applicable to
• all Distribution Licensees in the state of Delhi
• shall come into force from the date of notification in official gazette.
Demand Side Management:
DSM means actions of Discom facilitate change
in the pattern of end use and shall include : Any increase/decrease in demand
Shifting the demand between high & low peak
Managing the intermittent load demand
Objective to reduce the power purchase or
distribution licensee cost.
CERC Indian Electricity Grid Code (IECG) regulation 2010, mandates each
Distribution Licensee to formulate and implement Demand Side Management Schemes
2BSES Rajdhani Power Limited
DERC Demand Side Management (DSM) Regulation-2014
-
Every Distribution Licensee shall undertake/implement DSM related policy/activity programs
with an objective to lower the overall cost of electricity which shall include measure/principles to:
Control, reduce and impact of Electricity Demand
Encourage consumers to amend their electricity consumption pattern both w.r.t. timing and level of electricity demand.
Complement supply side strategies to help utilities to avoid or reduce a) costly capacity addition b) costly power purchase
Reduce environmental damage by reduction GHG gases.
Protect the interest of consumers and shall result in overall reduction of tariff for all consumers
3BSES Rajdhani Power Limited
DERC DSM Regulation- DSM Objective
-
Every Distribution Licensee constitute DSM cell within one month of adoption of this regulation.
Every Distribution Licensee shall make DSM an integral part of day to day operations and undertake planning, designing & implementation of DSM programs.
Distribution Licensees may recover all justifiable costs incurred by them in any DSM activity by adding these costs to Annual revenue requirement (ARR) to enable funding through tariff.

Load Research – Definition
An activity includes:
study of the characteristics of electric loads
Load characteristics by various classes of consumers
general behavior of critical loads over the day/month
Importance of Load Research – Helps to know following:
How demand and consumption patterns change over time How do consumers differ in their energy useWhich consumer segments/appliances contribute most to peak demandWhat end-uses drive each customer’s load shape Identification of DSM programs and their ranking/priority based on their load impact

DR service provider notifies the participating consumers to drop or shift load according to pre-prepared plans.
Participating consumer curtails the load during DR event.
Load is reduced until the end of call. Call period depends upon BRPL.
BRPL notifies DR service provider of the event end and (SP) notifies participating consumer
DR Service provider calculates curtailment supplied by meter data & Internationally approved standard methodology.

49BSES Rajdhani Power Limited
Came up with a unique solution to overcome the Barriers to the adoption of Rooftop Solar in Delhi
-
RESCO Proposal
Barrier-1: Upfront CostConsumer enjoys Solar Savings on his
Electricity Bills without any Investment
Barrier-:3Maintenance/
Reliability
Get Free Electricity through Solar after
9-10 years!
Consumer also has a flexibility to own the plant at any duration
by paying a defined % of the cost of the system
No Upfront Payment
Consumer pays only on the basis of solar energy
generated
After 9~10 years: Own the plant for
free and Enjoy FREE Electricity thereafter!
Enjoy the benefit of Electricity Savings through
Solar Energy generated on your Rooftop

Implementation Plan …How to reduce upfront cost.
VAT
• At present rate (12.5%) Rs 385.
• Request to government to reduce/exempt VAT for scheme
SEEP
Fund
• BEE-SEEP fund permits a subsidy of Rs 500 per fan.
• Discussions are going on with BEE.
Govt .subsidy
• 50% subsidy on Tariff for consumer up to consuming 400 units.
• Subsidy on appliances rather than units.
BSES Rajdhani Power Limited

Option-2: Request to BEE to Fund from BEE SEEP Fund
SEEP is Super Energy Efficient Program of BEE to Fund Super Efficient Fan
Manufactures to fill the price gap of Super Efficient Fan and Conventional Fan
Bureau of Energy Efficiency-SEEP Fund can help to reduce the further
Rs 500 cost per fan For all Consumers.
S.No Parameter Value Unit
R1 BEE-SEEP Fund amount available 50 Million$
R2 Fans to be sold under this scheme 5 Million
R3 Rebate to each Fan under scheme((R1/R2)*10) 500 Rs/fan
For a target sale of 1 lakh
fan a request to BEE for investment
of Rs 5 Crore
BEE has agreed to help in this regards

Air Conditioner Scheme-Features
As per Load Research Air Conditioner is top most Peak Load
contributor appliance.
Objective of Scheme:
To Incentivise replacement of old
Non-star rated AC by buying of 5 star
AC or Inverter AC at discounted rate.
Key findings:
• 51% AC are non-star rated.
• 1.5 TR AC are most common.
• Window AC usage is high.
• Consumers interested to
Purchase 3 star AC due to low price.
• Coincidence of Commercial &
Domestic consumers cause peak.
Features of Scheme
• For Domestic consumers ( consuming up to 1200 units/ month).
• Scheme will on the first come first serve basis – limited 20000 ACs only.
• Discount – Approx cost difference 3Star Vs 5 Star.
