B O N N E V I L L E P O W E R A D M I N I S T R A T I O N Page 3 What is BPA?  BPA helps fund and manage the largest fish and wildlife program in the world  Since 1980, BPA’s conservation efforts have saved more than 1,000 average megawatts for the region. That’s enough electricity to serve a city about the size of Seattle

Page 5 Unique challenge  We have more than 3,000 megawatts of wind power connected to our grid today and expect to have up to 6,000 MW by 2013.  Looking to use smart grid technologies to potentially manage load (need to find more places to put extra electricity) in addition to shifting peak load. Wind connected to BPA’s Transmission System
