Regulated Generation Business Model � Customers bore supply cost risk � Inefficient price signals to customers � Shareholder returns disconnected from performance Regulated generation model had problems. 9

Competitive Generation Business Model � Generators bear supply cost risk � Efficient price signals to customers � Shareholder returns linked to performance � Reduced air emissions � Lower fuel-adjusted wholesale prices Competitive generation model is better. 10

Complete the Transition � Wholesale Market � Implement forward capacity auction (LICAP settlement) � Transmission � Platform for competitive markets � Continue infrastructure expansion � Retail Market � Continue energy efficiency programs � Expand real-time pricing 11
