1 October 26, 2009 Impact of Energy Efficiency and Demand Response on Electricity Demand Perspectives on a Realistic United States Electric Power Generation Portfolio: 2010 to 2050 Presented by Lisa Wood Executive Director

2 Talking Points The Institute for Electric Efficiency Why is energy efficiency the first fuel for the electric power industry? What regulatory structure are in place to foster electric utility energy efficiency investments? What can we expect to achieve with energy efficiency and demand response by 2020? What is driving growth in energy efficiency and demand response? 2

3 Institute for Electric Efficiency Mission and Governance To advance energy efficiency and demand response (DR) among electric utilities. Management committee of 17 CEOs of IOUs. Chair, Jeff Sterba, PNM. Advisory committee of leading energy efficiency advocacy organizations and policy makers Role of IEE Provide resources/information/best practices re: regulatory models for energy efficiency and programs Provide forum for EE leaders for dialogue on advancing energy efficiency (industry, advocacy, and government leaders) Identify and provide thought leadership around key energy efficiency issues for electric utility industry 3

4 Energy efficiency is fundamental to the power business our 1st fuel! In US, 40% of CO 2 emissions come from generation sector Energy efficiency is a cost effective way to: Reduce carbon emissions Moderate the expected growth in electricity demand Average cost = $0.035 per kwh saved Savings today about 70 billion kwh and 30 GW of summer peak demand

5 Energy efficiency critical in proposed federal climate legislation Waxman-Markey climate change bill HR 2454 (passed June, 2009) Carbon reduction goals EE will play a major role 17% below 2005 levels by % below 2005 levels by 2030 Efficiency and renewable electricity standard: 20% by /4 can be met by energy efficiency (5% of the 20%) Governors can petition for up to 8% of the 20% to be met by EE 18 states already have energy efficiency resource standards (EERS). Number expected to grow. 29 states (including DC) have RPS. 7 states allow EE to act as a resource in the RPS. 5

Energy efficiency forecasts EPRI: 372 TWh (maximum achievable potential) to 473 TWh (economic potential) saved by 2020 (Jan. 2009) McKinsey: 1,080 TWh saved by 2020 (July 2009) Peak load reduction forecasts EPRI forecast: 79 GW (realistic achievable potential) to 147 GW (maximum achievable potential) reduction by 2020 (Jan. 2009) half due to energy efficiency; half due to demand response (DR) FERC DR forecast: GW reduction by 2019 (June 2009) 7

13 Demand response (DR) defined Load shifting by retail end-use customers typically during summer peak demand due to Dynamic rates or other rate designs that incent customers to shift load during high priced periods (e.g., pricing programs) Cash incentives to curtail or shift usage from peak to off-peak periods (e.g., direct load control programs) DR events can be triggered by Economic conditions (prices spikes) Reliability conditions 13

19 Energy efficiency and demand response are critical resources for electric utilities and a national priority going forward Energy efficiency will play a key role in dampening energy usage growth. And, is least expensive way to reduce carbon emissions. Demand response will play a key role in flattening peak demand in U.S. over next decade. A few states now have peak demand reduction goals (e.g., MD, Ohio, and PA) Smart meter platform and home area networks will open up new innovations and applications for DR and EE. 19
