3-April, 2012 Capacity Building of CSOs by VIKSAT, Ahmedabad 25/2 What is DSM? DSM means – Demand Side Management In terms of Energy supply & demand – DSM means managing energy demand within the limits of energy supply by reduction of energy demand using efficient techniques & technologies. With particular reference to electricity demand & supply fluctuations occur within a cycle of 24 hours as also during 12 months cycle – i.e. seasonal demand. Increase in energy demand of a nation is affected by overall growth of industries and change in life style of people.

3-April, 2012 Capacity Building of CSOs by VIKSAT, Ahmedabad 25/3 The NEED With rapid development and growth of the nation Energy Demand is increasing. Inspite of plans to increase resources and add new generation capacities it is becoming difficult to match the supply with the demand because of resource and cost constraints. Creating new energy sources will increase environmental hazards as power plants are the biggest source of pollution. India depends on imported (oil) energy to meet about 75% of its total demand. So we have spend a huge sum of our hard earned FOREX for importing oil.

3-April, 2012 Capacity Building of CSOs by VIKSAT, Ahmedabad 25/4 The energy intensity of India is among the highest in the world. We consume double the amount of energy for manufacturing and rendering services as compared to some of the developed countries. So it is essential that we become more efficient and reduce our energy intensity by preventing wastage and adopting energy efficient pattern of growth.

3-April, 2012 Capacity Building of CSOs by VIKSAT, Ahmedabad 25/5 The Concept Control and Manage the demand within sources of supply. Manipulate and Manage peak load and off-peak load demands through load management. Adopt Energy Efficient techniques & technologies to reduce energy demand in all consumer sectors. Promoting low energy intensive industrial development Use Renewable Energy Sources wherever possible – solar, wind, bio energy, hydel/tidal, geothermal energy sources. Moderation of energy use.

DSM program can be classified under the following three categories : Implication of DSM in utilities 1. Energy Conservation Program : promote the application of energy efficiency measures, equipment such as lighting, air-conditioning, motors in different customer segments. The EC programs are especially designed to directly reduce energy consumption and indirectly reduce the peak demand. 2. Load Management Program : control, curtail or shift the load demand periodically on a daily or seasonal basis according to peak demand requirement or constraints. This program normally result in a decrease in peak demand but may or may not result in a decrease in consumption. 3.Increased Electricity Demand Program : may be used periodically on daily or seasonal basis in order to fill the valleys when the network is fed by run-of-river power stations. They are generally referred to as strategic power increase or surplus consumption measures.

3-April, 2012 Capacity Building of CSOs by VIKSAT, Ahmedabad 25/7 The Power Scenario All India installed capacity is about 1,82,689 MW. All India Generation is about 800 BU Power Deficit - Peak Demand – 10.5%, Energy – 8.2% Per Capita Energy Consumption – India kWh/year– World Average – 2800 kWh/yr Coal based TPP – 65% (84% Generation) Capacity Addition in 12th Plan is MW Electricity supply increased 60%, household access by 10% in last decade – however –Half of Indias rural households do not have access to electricity i.e one third of the world population without electricity. Making India the largest population without electricity. –25% of consumers are poor - paying > Rs 150 per month

3-April, 2012 Capacity Building of CSOs by VIKSAT, Ahmedabad 25/11 Oil In India Will last - World (42 years) & India (20 years) India has 0.5 % of world oil reserves Oil accounts for 31 % of our primary energy. Transport consumes 42 % followed by domestic and industrial, both 24 % In 2011 Indias oil import burden will exceed 5% of GDP for only the third time in history if prices average the current level of $92/bbl for the entire year.

3-April, 2012 Capacity Building of CSOs by VIKSAT, Ahmedabad 25/12 Power generation accounts for much of the increase in primary energy demand, the overall power generation in the country has increased from 264 Billion units during to Billion Units during The country is facing power shortages : Peak shortage = 10.2 %, Average shortage = 9 % Coal remains the main source of power generation. Higher energy demand drives up imports of oil, gas and coal, and greenhouse gas emissions. India is the fourth largest greenhouse gas (GHG) emitter in the world with CO2 emission being Mt for the year 2006.
