UTILITY DRIVEN DEMAND SIDE MANAGEMENT - A STRATEGIC APPROACH TO ENERGY CONSERVATION AND IT’S EXPERIENCE AT JAIPURDISCOM Deepti Mathur Assistant Engineer(DC &DSM) Jaipur DISCOM Jaipur
Economic growth is desirable for developing countries, and energy is essential for economic growth. If India is to achieve the targeted growth in GDP, it would need commensurate input of energy, mainly commercial energy in the form of coal, oil, gas and electricity. India’s fossil fuel reserves are limited. The known reserves of oil and natural gas may last hardly for 18 and 26 years respectively at the current reserves to production ratio. India has huge proven coal reserves (84 billion tonnes) may last for about 200 years but the increasing ash content in Indian Coal as well as associated greenhouse gas emission are the major concern. In the business as usual scenario, the exploitable coal may last for about less than 100 years Introduction
ENERGY DEMAND AND SUPPLY On the energy demand and supply side, India is facing severe shortages 70% of the total petroleum product demand is being met by imports, imposing a heavy burden on foreign exchange (Rs.80,000 crores per year). Country is also facing electric Power Shortages Peak shortage –11% Average shortages – 7% Additional 100,000 MW required by 2012 Approximately Rs billion investment required Further, the per capita consumption in India is too low as compared to developed countries (just 4% of USA and 20% of the world average). The per capita consumption is targetted to to grow to about 1000 kWh per year by 2012
GROWTH OF INSTALLED GENERATING CAPACITY (MW) MW The Indian Power sector has increased it’s installed capacity from 30,000 MW in 1981 to over MW as on June 2008.
IMPORTANCE OF ENERGY CONSERVATION Energy efficiency/conservation measures can reduce peak and average demand. One unit saved avoids 2.5 to 3 times of fresh capacity addition. Investment in energy efficiency/energy conservation is highly cost effective. Can be achieved less than Rs.10 million/MW Also avoids investment in fuel, mining, transportation etc. Keeping the above factors in view and also to provide a policy guidance,Government of India enacted the Energy Conservation Act,2001
Reasons for the inefficiencies in the end use system in India Irrational tariff Use of obsolete Industrial processes and equipments Lack of awareness towards energy conservation Inadequate energy efficiency standards and labeling systems No financial incentives etc.
Steps Taken by the Utilities The power sector has been focusing on new supply and improving supply efficiency and reducing T&D losses The major omission is the neglect of Demand Side Management opportunity in India. There is a clear role and potential for utility driven DSM programs in India.
What is DSM Utility driven DSM can be defined as a concept in which a Power utility, such as an vertically integrated SEB or an unbundled distribution utility manages the demand for power among some or all its customers to meet its current or future needs
Ways to Implement DSM in Indian Utilities By improving energy efficiency of end use appliances - the reduction of kilowatts hours(Kwh) of energy consumption Demand load management-the is reduction of (Kw) of power demand or the displacement of demand to off-peak times.
Results of the activities Modify the load curve profile Reduce the network ’ s technical and non- technical losses Influence and change the equipment – buying habits of customers so that they prefer to adopt efficient technologies Change consumers ’ energy-using habits and behavior.
Demand Side Management Planning Load Research Evaluating Load –curve modification objectives Market Research Understanding the demand Evaluating and selecting DSM measures Determining DSM programme opportunities Selecting potential technologies
DSM PROGRAMME DESIGN Pilot Programmes- 1.To demonstrate the application of several alternative technologies and observe the way in which they can affect the load curve. 2.To determine the economic and technical feasibility of certain technologies and to zero in on the technology suitable for a large-scale programme. 3.To define and test the capacity of partners on the market, such as manufacturers, distributors, dealers, and engineering! architecture specialists, to determine if they are in a position to participate in a DSM programme. Large Scale Programmes
Six important components of a detailed design plan Eligibility of the measures Choice of programme category Financial incentives Programme management follow-up Cost/benefit analysis Marketing strategies DSM PROGRAMME DESIGN
