2. Slide Header
• Wikipedia
Actions that influence the quantity or pattern of use of energy
consumed by end users.
• World Bank
Systematic utility and government activities designed to change the
amount and/or timing of the customer’s use of electricity for the
collective benefit of the society, the utility and its consumers.
• Forum of Regulators (India)
“Demand Side Management” means the actions of a Distribution
Licensee, beyond the customer's meter, with the objective of altering
the end-use of electricity - whether it is to increase demand,
decrease it, shift it between high and low peak periods, or manage it
when there are intermittent load demands - in the overall interests of
reducing Distribution Licensee costs.

3. What is Power Distribution Business?
Meet the demand with Efficiency and Reliability so that Demand and
Supply on the electricity grid will be in balance at all times
Efficiency Means : Low power cost, low loss, low operational cost, best
customer services
 Reliability Means : Power Quality and Availability

7. • Energy efficiency (EE)
– Permanent reduction in consumption
across the load curve.
– Provides same or better energy service with
fewer kWh.
• Load Management (or Demand
Response)
– Temporary reduction in consumption at
times of system peak.
– May be associated with curtailment of
service.
Change: Technology, Price, Behavior,
Standards
DSM: Two Main Flavors

8. • Permanent reduction in consumption.
• Occurs across most hours of the load curve.
• Provides same or better energy service with fewer kWh.
– Example: replacing incandescent lighting with fluorescent
lighting.
– Example: replacing low-efficiency motor with high-efficiency
model.
• Reduces electric system energy usage and fuel needs.
• May or may not reduce system peak demand and
capacity needs.
DSM - Energy Efficiency

9. Defining Energy Efficiency
• Energy efficiency is a way of expressing the energy
performance of an energy-consuming device or system.
• Energy efficiency generally relates energy consumption to
some other measure:
– GJ per unit of production output
– kWh per m2 per year (typical for buildings)
– kWh per 100 kg of ice (ice makers)
– lumens per watt (for lighting)
– kilometers per liter (automobiles)
• In some cases, energy efficiency is expressed without
reference to anything else.
– Example: for electric motors energy efficiency is expressed as %
conversion of electricity to useful work.

10. • Replacing inefficient end-use technologies with more-
efficient models (non star with star labeled appliances).
• Retrofitting whole buildings with insulation, better
windows, better equipment to improve efficiency.
• Operating buildings and industrial plants more efficiently via
advanced use of information and control systems.
• Installation of efficient equipments and appliances at the
very first stage.
QUESTION: What are some examples?

11. Defining Demand Response
• Demand Response refers to changes in electric usage by
end-use customers from their normal consumption
patterns in response to changes in the price of energy
over time or to incentive payments designed to induce lower
electricity use when prices are high or system reliability is
in jeopardy. DR salient features:
– Temporary reduction in consumption.
– Reductions targeted at a few specific hours, typically coincident with
system peak.
– May be associated with curtailment of service (but may not be
perceived or experiences as curtailment).

15. Training of Trainers for Capacity Building of DISCOM
Why are we concerned (1) – unserved demand
 Peak and energy shortage at around
5%.
 About 300 million consumers are not
connected to grid.
 Average load shedding of 6-10 hours
in many states.
 According to World Bank estimates,
almost 7 % of annual sales of Indian
firms is lost as a result of electrical
outage, compared to 3 % across the
world.
 Additional peak or base load
generating capacity, transmission and
distribution facilities required to serve
the unmet demand.

cost
Increase in land
price
Increasing
Operating and
Maintenance Cost
Increasing
environmental
compliance cost
 Average electricity prices are
highest in India amongst the
BASIC countries.
 Increasing trend in tariff bids by
generators in competitive bids
over the last 3-4 years.
 Average price will tend to
increase due to the increase in
land cost, O&M, and fuel cost.
 Prices will increase further if
environmental compliance is
made stringent.
Case 1 Long term bid prices – INR/Unit

18. Training of Trainers for Capacity Building of DISCOM
Why are we concerned (4) – environmental impact
 As of July 2014, coal-based power plants accounted for
140GW, i.e. almost 65% of the total installed capacity
while contributing 73% in the total generated electricity.
 Out of the total 1,100 million tonne of GHG emissions from
the energy sector in 2007, emissions from electricity
generation was 719 million tonne (CO2-eq) and 90% of
this came from coal power plants.
 SPM, NOx, SOx and Hg are the other critical air pollutants
of concern from a coal power plant.
 About 80 GW coal power addition is planned in the 12th
five year plan.
 Other environmental impacts during mining and
transportation.

19. Why are we concerned (5) - DISCOM’s Poor Financial Health
(Source: PFC)
 Aggregate losses of the utilities with and without subsidy received basis increased over the
years.
 Performance of the utilities has been varying - states of West Bengal, Sikkim, Delhi and
Kerala have earned profits (without subsidy) on aggregate basis during the year 2011-12.
 However most states increased tariffs in last 2 years in spite of elections. Also a number of
ailing states accepted FRP which puts stringent conditions on utilities to improve
performance.

29. Key features of Model DSM Regulation, 2010
• Constitution of DSM cell
• DSM process framework
• Roles and responsibility of distribution licensee and ERC
• DSM objective and target setting
• Timeline of activities
• Indicators for cost effectiveness
• Mechanism for cost recovery
• Incentives to distribution licensee
Note: The regulation aim to provide a guiding document to the States while
preparing DSM Regulations. Modifications/additions may be required to
incorporate State specific conditions/attributes. ERC may also need to
issue detailed guidelines to DISCOMs to properly explain the requirements
and modality of execution.

30. Constitution of DSM Cell

- Consistent with BEE’s
plan

34. Mechanism for cost recovery
• Distribution Licensee shall identify the net incremental
costs, if any, associated with planning, design and
implementation of programmes
• Distribution Licensee may propose methodology for
recovery of net incremental costs through tariff or any other
mechanism
• In order to qualify for cost recovery, each program must be
i. Approved prior to implementation
ii. Implemented in accordance with the approved
program plan and
iii. Implemented cost effectively

35. Specifics not detailed in the Model DSM regulation
• DSM cell – Team’s desired Strength, Expertise, Experience
not indicated
 Objectives – Primarily based on shortage and savings.
What about reliability, affordability, sustainability?
• Goal/Target setting – no mention of economic potential
• Cost effectiveness – parameters not defined. Individual

Demand Response
• Saving energy by taking an action that often
becomes a habit. e.g. Turning of lights when
you leave the room
• Demand response – A reduction or shift in
energy use during critical periods for short
duration delivered immediately. Demand
response is only needed occasionally and just
for a few hours during the critical time.
Demand Response, Energy Conservation and Energy Efficiency provide an
alternative to new generation, helping stabilize the grid, and can help avoid blackouts.
