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


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


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.


DERC DSM Regulation- DSM Principle

Conduct Load Research & Consumer survey

Load forecasting at Segment & end level

Conduct DSM & Demand Response potential studies

Short & Long Term DSM targets

Submission of Annual DSM plan

Submission of Annual DSM Budget


DSM Implementation- Key Actions

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

Removing the Barriers to the Adoption of Rooftop Solar

Lack of Awareness

High Upfront Cost

Uncertainty about Reliability/ Maintenance

BRPL RESCO


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

Price Gap of Rs 1480 need to be filled. 59BSES Rajdhani Power Limited

Cost of Rs 3080 is the price of

Super Fan for this Target category

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.


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

Plan of Energy Efficient Air conditioners


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.


Domestic consumer with Non star

AC

DSM Scheme --- Air conditioner

Agrees to replace old used AC

Surrender old AC and buy new 5 star AC

Subsidy to buy 5 star AC

All payment – on lumsum basis

Old AC will be disposed

Financial Subsidy:

1 Ton : 4800 Rs per AC

1.5 Ton : 6400 Rs per AC
