    • Investing in our Energy Future Secretary Steven Chu U.S. Department of Energy Washington, D.C. September 21, 2009
    • Recovery Act is making a down payment on a clean energy economy Creating jobs immediately Investing in our energy infrastructure to provide lasting value “The nation that leads the world in creating a new clean energy economy will be the nation that leads the 21st century global economy.” -- President Obama
    • “We'll fund a better, smarter electricity grid and train workers to build it -- a grid that will help us ship wind and solar power from one end of this country to another.” “Think about it. The grid that powers the tools of modern life -- computers, appliances, even BlackBerrys -- looks largely the same as it did half a century ago.” President Barack Obama To meet the energy challenge and create a 21st century energy economy, we need a 21st century electric grid
    • Recovery Act will double non-hydroelectric renewable generation Billions of kilowatt hours Source: EIA -- An Updated Annual Energy Outlook 2009 Reference Case
    • Recovery Act will set the stage for widespread deployment of plug-in hybrid electric vehicles Recently made $2.4 billion investment in advanced batteries – the largest battery investment in world history Today, 99 percent of batteries for hybrids are made in Japan
    • The Recovery Act invests in grid modernization Grid Modernization- $4.5 billion including Smart Grid Investment Grants and Demonstrations $750 million for WAPA and BPA – total transmission loan of $6.5 billion in guarantees borrowing authority
    • Today, we are announcing: The availability of $100 million To train a new generation of utility workers $44.2 million in awards to State Public Utility Commissions To hire and retrain PUC staff as utilities ramp up Smart Grid activities
    • The Smart Grid: What is it? • Dynamic optimization of grid operations and resources • Incorporation of demand response and consumer participation Measurement Visualization Automation
    • Smart Grid is a key enabler to Grid Modernization Renewable Integration – Addressing variability and intermittence of large-scale wind generation Energy Storage – Providing regulation and load shaping Load Management – Making consumer demand an active tool in reducing the peak System Transparency – Seeing and operating the grid as a national system in real-time Cyber Security and Physical Security –Securing the physical infrastructure and two-way communication and data exchange
    • Solar energy sources are highly variable Output from an 8MW solar PV 81 % drop in panel in 5 minutes Colorado on 9/4/08 High variability due to clouds Xcel Energy – Alamosa System 11
    • Wind requires substantial balancing reserves Jan. 5-25, 2009 10000 9000 8000 7000 6000 MW 5000 4000 BPA TOTAL WIND GENERATION 3000 2000 BPA BALANCING AUTHORITY AREA LOAD 1000 0 1/5/09 1/6/09 1/7/09 1/8/09 1/9/09 1/10/09 1/11/09 1/12/09 1/13/09 1/14/09 1/15/09 1/16/09 1/17/09 1/18/09 1/19/09 1/20/09 1/21/09 1/22/09 1/23/09 1/24/09 1/25/09 Date/Time (5-min increments) 12
    • BPA is installing 14 anemometers for next-hour wind forecasts to adjust generation and make more efficient use of combined wind, hydro and other resources. They are also working on Dynamic Transfer to reliably let a power plant in one balancing authority supply reserves to another balancing authority. 13
    • Variable Generation Affects Grid Operations No wind 11% renewables 23% renewables 35% renewables 14
    • Smart Grid is a key enabler to Grid Modernization Renewable Integration – Addressing variability and intermittence of large-scale wind generation Energy Storage – Providing regulation and load shaping Load Management – Making consumer demand an active tool in reducing the peak System Transparency – Seeing and operating the grid as a national system in real-time Cyber Security and Physical Security –Securing the physical infrastructure and two-way communication and data exchange 15
    • Energy Storage is critical to grid operations 16
    • Energy Storage is Critical to Grid Operations 17
    • Pumped Storage Pumped Storage can provide: Rapid response in “pump-up” and generating modes to offset wind generation variability Store wind energy during lower value periods Prevent wind curtailment and avoid new transmission investments Grand Coulee Dam Additional capital and operating costs have to be compared to the cost of spinning reserves Energy losses (~20%) related to storage 18

    • Peak Reduction is Paramount Hourly Loads as Fraction of Peak, Sorted from Highest to Lowest 100% 90% generation 80% L o a d F a c to r (% ) 75% Generation 60% Distribution 40% 5% = ~440 hrs/yr distribution 20% 0% 0% 20% 40% 60% 80% 100% (8,760 hrs) Percentage of Year >25% of distribution and >10% of generation assets are needed less than 5% of the time ($100s of billions of investments)
    • Achieving peak demand reduction requires a Smart Grid and dynamic pricing 25% Other DR Interruptible Tariffs 188 GW, Light blue: 20% of peak 200 DLC 20% reductions Pricing w/o Tech Peak Reduction (GW) through % of Peak Demand Pricing w/Tech 138 GW, 150 14% of peak dynamic 15% pricing 82 GW, 100 9% of peak 10% Dark blue: 38 GW, 50 4% of peak 5% reductions through Smart Grid 0 0% Universal All Demand technology Business as Expanded advanced Response tools usual current best metering (e.g. direct load practices and control) fully dynamic deployed pricing Source: FERC, June 2009 National Assessment of Demand Response Potential
    • Changing Consumer Behavior Empower consumers through better information Give consumers the tools and incentives to manage their energy use and eliminate waste Demand response programmability must be as easy and automatic as possible.
