This presentation discusses demand side management (DSM) in the Indian power sector. It notes that while India has significantly increased its power generation capacity, demand continues to outpace supply, leading to energy deficits and load shedding. DSM aims to balance supply and demand through strategies like controlling energy usage during peak times and load levelling. Examples provided include interruptible loads and incentivizing off-peak usage. Barriers to DSM include a lack of public information and support mechanisms. The presentation outlines a DSM planning process and concludes that widespread adoption of DSM through energy efficiency, new technologies, and load management could help reduce load shedding issues caused by current energy and peak power shortages.

More than trebled installed capacity in the last
two decades.
Large energy deficit and still larger peak
power deficit.
Long hours of load shedding in different parts
of the country.

6. The demand is likely to grow at a pace more than
envisaged
Economy growing rapidly
Expected growth might be much higher
Growth is linked to energy availability
We must generate more energy for the growth of
economy

7. Controlling the quantity of energy used at
specific times to
reduce system peak demand
load levelling
reduce overall system demand
energy efficiency
balance system supply and demand
demand response

8. Maintain minimum demand levels to
minimize waste
prevent strategic base load plant shutdowns
Keep a low maximum demand
avoid building new power plants
reduce emission of GHG & other pollutants
lower use of peaking plant power

During periods of high demand
Interruptible customers
During periods of low demand
Energy storage
Energy incentives
Ex: Off-peak incentive rates
Minimizing Peak Power Requirements
Energy Efficiency Programs
Smart Metering (real-time pricing)

18. Energy and peak power shortage which leads to load
shedding
Normally unannounced
Is there a way to overcome load shedding inspite of the
shortages?
18

19. What consumers do during load
shedding
• They suffer, silently and helplessly
• Some have invested in diesel generators
• Many have purchased inverters
• This is expensive for the middle class and out of reach
for the poorer section of society
• They cater to a part of the lighting load only
• Difficult to run refrigerators, water pumps ,AC
• Inverters are energy guzzlers
– Consume nearly twice the energy to charge their
batteries after they have been used
– Further increases the loss due to harmonics
19

20. Load management using load rationing is actually an
effective way forward for Demand Side Management
It will be a far more effective and a sure way to manage
peak demand at the time of shortages as compared to
influencing consumer behavior using TOD tariffs
It will help in conserving energy
The energy consumed by the batteries of the
innumerable inverters will also be saved.

21. To achieve widespread DSM success
Energy efficiency
New technologies
Widespread load levelling use
Real-time pricing
Off peak incentives
Energy storage

24.  Without the more effective use
of energy we would have to use 50%
more energy than we actually do
today.
 Demand Side Energy Management
focus on harnessing clean energy.
 Reliability, security and
quality of power supply are the
main concern of DSM.

25. We have achieved
many mile stones
yet the
further journey
to achieve
high customer satisfaction
is on the horizon through DSM
