UTILITY DRIVEN DEMAND SIDE MANAGEMENT -

A STRATEGIC APPROACH TO ENERGY CONSERVATION

AND IT’S EXPERIENCE AT JAIPURDISCOM

Deepti MathurAssistant Engineer(DC &DSM)Jaipur DISCOMJaipur

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 SUPPLYENERGY 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. 8000 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

The Indian Power sector has increased it’s installed capacity from 30,000 MW in 1981 to over 144912 MW as on June 2008.

IMPORTANCE OF ENERGY IMPORTANCE OF ENERGY CONSERVATIONCONSERVATION

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

OUR AIMS & OBJECTIVES

• ENERGY EFFICIENCY FOR END USERS

• ENERGY SAVINGS IN ALL SECTORS………

• HENCE INCREASE POTENTIALS FOR MORE

REVENUE GENERATING CUSTOMERS FOR THE UTILITY

• GOOD QUALITY OF SUPPLY-SATISFIED CUSTOMERS FOR THE UTILITY

DESIGNING OF LIGHTING PROJECT FOR CORPORATE OFFICE.

VISIT TO VARIOUS INDUSTRIES AND SUGGESTING MEASURES FOR POWER FACTOR IMPROVEMENT.

DEMONSTRATION OF STREET LIGHTING POWER SAVER EQUIPMENT.

COMPREHENSIVE AWARENESS CAMPAIGN

WITH THESE AIMS WE MARCHED AHEAD……..

Load Research …..

• WE CARRIED OUT END USE LOAD RESEARCH:

Identification of different categories of consumers.

Survey format design of different categories.

Conduct survey of selected consumers.

Collection, Compilation & Analysis of load data. Development of load profile curve of each category.

THE LANDMARKS…..• DOMESTIC SECTOR:-

• AGRICULTURE SECTOR:-

• INDUSTRIAL SECTOR:

• MUNICIPAL SERVICES:

OUR GOALS NOW……

AFTER EXPLORING THE RESULTS OF THE DEMONSTRATION PROJECTS

• IT WAS EVIDENTLY INFERRED THAT THE END USE EFFICIENCY OF AGRICULTURAL PUMP SETS IS DISMALLY LOW.

• THE AGRICULTURE TARIFF HIGHLY SUBSIDIZED AND USALLY LINKED TO THE CONNECTED LOAD, THE FARMERS HAVE LITTLE INCENTIVE FOR EFFICIENT USE OF ELECTRICITY.

• THE ENERGY SALES TO THE AGRICULTURE SECTOR IN JPDISCOM ARE AROUND 23%

• THE ENERGY SAVINGS BY REPLACING GI PIPES IS 15% AND AS KNOWN, BY REPLACING THE EXISTING PUMP SETS WITH ENERGY EFFICIENT PUMP SETS THE SAVINGS ARE ESTIMATED TO BE AROUND 25%, HENCE OVERALL ENERGY SAVINGS ENVISAGED WILL BE AROUND 30%

REVOLUTIONIZING THE AGRICULTURE SECTOR….

WITH ALL THE INFERENCES DRAWN :-• A STUDY OF ENERGY EFFICIENCY IMPROVEMENT OF THE

PUMPSETS HAS BEEN UNDERTAKEN . • IN THE FIRST PHASE, ONE OF THE 11KV FEEDERS(BASDI FEEDER)

UNDER FPR SELECTED WHICH HAS AROUND 243 PUMP SETS. • THE FINANCIAL GAINS FORSEEN:- TREMENDOUS ENERGY SAVINGS POTENTIAL FROM 2,26087 PUMP

SETS OF JAIPUR DISCOM - A SUBSTANTIAL DEMAND SAVING DEFERRED ADDITION OF CAPACITY AT THE GENERATING END LEADS TO REDUCTION IN CARBON DIOXIDE EMISSIONS SAVING OF HUGE AMOUNT OF COAL. EARNING DOLLARS THRU CARBON TRADING MECAHNISM.

Improving Energy Efficiency in Domestic Lighting

Major Imitative has been taken by Jaipur Discom in improving lighting efficiency of domestic consumers.

Under the Bachat lamp Yojna of BEE three companies M/s Green point Energy, Jaipur, M/s Banyan Environmental Innovations, Hyderabad and M/s Energy Mad & Secure Meters have been given the Project work in different areas of Jaipur Discom.

Under this project two incandescent bulbs of each 15.5 lac domestic consumers will be replaced by CFL at a cost of Rs. 15/- each.

Jaipur Discom will not incur any expenses. All the cost will be borne by these companies which they shall

recover by earning carbon credits under the Clean development Mechanism(CDM).

This shall reduce the peak demand by 140 MW and the savings of electricity of the tune of 250 MU annually . The consumer shall reduce his annual electricity bill almost by Rs. 700.

JVVNL SHALL USHER IN A PRISTINE ERA ………………

BY OFFERING MORE CONSISTENT AND IMPROVED QUALITY OF POWER SUPPLY TO ITS VALUABLE CUSTOMERS ALONG

WITH A HEALTHIER MILIEU

AND

DEDICATED EFFORT TO
