1 Creating Our Future: Meeting the Electricity Technology Challenge Steven Specker President and CEO 9 Summer Seminar August 3-, 9

2 The Electricity Technology Challenge Defining the Challenge Understanding the Challenge Meeting the Challenge

3 Defining the Technology Challenge De-carbonize the electricity infrastructure Meet binding economy-wide CO reduction targets Provide reliable, affordable, and environmentally responsible electricity to consumers Two Key Metrics: CO Emissions and Cost of Electricity 3

4 The CO Challenge 8 7 Historical Emissions Assumed Economy-wide CO Reduction Target 5 = 598 mmt CO 1 = 3% below 5 (583 mmt CO ) Billion tons CO 5 3 Remainder of U.S. Economy Waxman-Markey goals as of July 1,9 = 17% below 5 (95 mmt CO ) 3 = % below 5 (37 mmt CO ) 5 = 83% below 5 (117 mmt CO ) 1 U.S. Electric Sector 8% Reduction in CO emissions from

5 The Cost Challenge 18 1 U.S. Retail Price of Electricity Cents/kWh (in 7 cents) U.S. Average Wholesale Electricity Cost Flat real electricity prices for past years what about the next years?
