INDIAN POWER SECTOR
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.

FUTURE OF DEMAND
The demand is likely to grow at a pace more than envisaged
Economy growing rapidly Expected growth might be much higherGrowth is linked to energy availabilityWe must generate more energy for the growth of economy
6
WHAT IS DSM?
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
7
Why balance supply and demand?
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
8
DSM Programs Include
Metrics
Actual Peak Reduction (MW)
Annual Effects (MWh)
Direct Load Control
Other Load Management
Energy Efficiency
9
Examples of DSM
Balancing Supply & Demand
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)10

Barriers to Achieving “Ideal” DSM
Lack of support mechanisms
Inadequate capital investment
Inadequate information to public
Split incentives

PROBLEMS
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
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
Effective way to DSM
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.

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

CONCLUSION 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.

We have achievedmany mile stones yet the further journey to achieve high customer satisfaction is on the horizon through DSM
