2 The Basics Bonneville Power Administration (BPA) markets power from 31 Federal dams, the Columbia Generating Station Nuclear Plant, and several small non- Federal power plants About 80% of the power BPA sells is hydroelectric. BPA accounts for about 30% of the electric power consumed within the region. 3,100 Federal FTE employees 2

5 Investing in Technology BPA s technology innovation agenda is guided by a strict logic and framework that links the agency s research goals to current business challenges and technology gaps facing the agency. This agenda supports three of the agency s strategic priorities: Preserve and enhance generation and transmission system assets and value; Advance energy efficiency; and Expand balancing capabilities and resources. Since 2005, BPA s Technology Innovation Office has pioneered an approach that ensures the agency is making shrewd investments in technology research. 5
