Scaling Up Energy Efficiency in India: Opportunities in the Electricity Sector
Dr. Jayant Sathaye, Dr. Amol Phadke and Ranjit BharvirkarEnergy Analysis Program
Lawrence Berkeley National LaboratoryBerkeley, CA
Presented at the Forum of Indian Regulators
25-26 September 2008
Work supported by the US Departments of State and Energy, and the ClimateWorks Foundation
Lawrence Berkeley National Laboratory
• Managed by the University of California for the US Dept
of Energy
• Founded in 1931, about 4000 staff
• 12 Nobel Prizes – IPCC (2008) – Jayant Sathaye
• Berkeley India Joint Leadership on Energy and
Environment (BIJLEE) program starting in October 2008
• Utility programs – — Distribution loss reduction
— Demand-side management programs
— Load research and generation planning
—Transmission reliability
— Renewable energy
Motivation
Electricity shortage accompanied by blackouts and load
shedding is common across India
In Maharashtra, electricity deficit reached 4800 MW in 2008
Affects industrial production quantity and quality,
Lower production and sales lead to reduced sales tax
payment
Government loses sales tax revenue
LBNL estimates sales tax loss of Rs. 9 /kWh not served
Shortage met partially by use of inefficient diesel and gasoline
micro generators with high CO2 emissions
Savings potential Energy savings potential of about 6800 GWh/year
CO2 savings potential of 3-5 Mt CO2/year
Project Concept: Improve efficiency of electricity use
Marginal cost of procuring new supply: 8-10 Rs./kWh
Marginal cost of demand reduction: 0.9 - 5 Rs./kWh demand or 0.6 – 3.2 Rs./kWh supplyAssuming 28% supply loss
LBNL Maharashtra study found that energy efficiency is the least
expensive and quickest option to reduce shortage

Energy Efficiency Opportunities in Delhi
• Jiangsu Province had saved 300 MW at the end of 2007
• Jiangsu targeting to save 462 MW or $197 million USD in 2 years, at a cost of Rs. 2.5/kWh

• PG&E and Maharashtra generation capacity is similar ~ 20-25 GW
• PG&E’s energy efficiency goals are increasing significantly
• California expects to meet approximately half of demand growth with energy efficiency through 2013
• PG&E 2006-08 energy efficiency budget of ~$1 billion

Demand-Side Management: California Approach
California Regulatory Commissions:
1. Public Utilities Commission and 2. Energy Commission
California Utility Companies, e.g. Pacific Gas and Electric (PG&E) implement DSM programs
Suppliers of efficient equipment
Critical Feature: Electricity Savings cannot be metered directly; Important to monitor and verify meter readings before and after efficient equipment is installed
Electricity Consumers
Commission orders utility companies to pursue DSM programsand allows cost recovery Provides financial and other incentives to
suppliers and/or consumers
Project: India Load Research and DSM Programs
Initiated in the state of Maharashtra
Maharashtra has the largest capacity in India – about 19,000 MW
All four major utility companies are participants in the project
Maharashtra State Electricity Board (MSEB) – unbundled into three companies
BEST (Muni)
Tata Power Company (Private)
Reliance Energy (Private)
Maharashtra Electricity Regulatory Commission (MERC) is the primary
counterpart
Utility companies have limited capacity for generation planning and load
research
No data collection on load components and forecasting
