WHAT IS DSM

“Demand Side Management” is themodification of consumer’s demand ofelectricity through various methods such asfinancial incentives and consumereducation

Usually the goal of DSM is to encourage theconsumers to use less energy during peakhours or to move the time of energy use tothe off-peak hours

WHAT IS DSM …..(CNTD)

DSM is universal and does not only apply to utilities, electricity or monopolies

IN SHORTLY, DSM = Large-Scale Deployment of Energy Efficient Equipment by use of specially designed Programmes

THE ISSUES

Load level a wasteful demand requires too much supply for the specific needs

Load shape high peaks,

little reserve capacity,

bottlenecks in transmission and distribution

FROM THE GRAPH

The peak demand of 225 KW is there for an average of 12 hours in a day

The base demand is 125 KW, which is much less than the peak demand of 4,300 MW

To meet the extra demand utility has toarrange additional installed capacity orpurchase power at high rate

Cntnd…..

Thus DSM will always try to encourageconsumers to:

Use less energy during Peak hours (PeakClipping)

Shift energy use to off peak hours (ValleyFilling)

NEED FOR DSM

Increasing energy requirement

Increasing threat of climate change and other environmental considerations

Energy security

Lack of other supply options

Huge scope for energy efficiency measures

NEED FOR DSM ….(CNTD)

Saving 1 unit of electricity at consumer endavoids nearly 2.5 times of capacity addition

1 MW capacity addition of thermal powerrequires Rs 6 crores for installation andanother Rs 3 crores for Transmission andDistribution

IMPLEMETATION OF DSM

There are 3 methods to implement dsm

1. ENERGY EFFIENCY

2. DEMAND RESPONSE

3. DYNAMIC DEMAND

Energy Efficiency:Using less power to perform the same tasks

Demand Response:Demand Response includes all intentional modifications to consumption patterns of electricity of enduser customers that are intended to alter the timing, level of instantaneous demand, or the total electricity consumption

Dynamic Demand: The concept is that by monitoring the power factor of the power grid, as well as their own control parameters, individual, intermittent loads would switch on or off at optimal moments to balance the overall system load with generation, reducing critical power mismatches

STEPS TO BE FOLLOWED

To charge higher prices during Peak Hours

Improving the efficiency of various end uses byusing energy efficient appliances, better housekeeping and reducing energy leakages. This isimportant for agriculture where energy efficiencyis very low (30-50%)

Promoting use of Energy Efficient Technologiesand addressing Aggregate Technical andCommercial (AT&C) Losses

CHANGE IN THE LOAD SHAPE

Adapts the load to the capacity of the system

Benefits of Demand Side Management

Customer Benefits Utility Benefits Societal Benefits

Satisfy electricity demands Lower cost of service

Reduce environmental degradation

Reduce / stabilize costs or electricity bill

Improve operating efficiency,Flexibility

Conserve resources

Maintain/improve lifestyle andproductivity

Improve customer service

Protect global environment

PROBLEMS OF DSM

It might result in higher utility costs for consumers and less profit for utilities.

Another problem of DSM is privacy: The consumers have to provide some information about their usage of electricity to their electricity company.

Dissatisfaction may arise among the consumers

FINAL THOUGHT….

DSM leads to,

i. Energy efficiency

ii. Industrial development

iii. Energy security
