The Bonneville Power Administration (BPA) is a federal agency that markets and transmits electricity generated at hydroelectric dams in the Pacific Northwest. It is one of four power marketing administrations within the Department of Energy. BPA was established in 1937 as part of the Bonneville Project, which was tasked with constructing dams and other infrastructure to harness the power of the Columbia River and its tributaries.
BPA operates and maintains over 15,000 miles of transmission lines, which carry electricity from the dams to cities and towns throughout the region. It also manages the sale of this electricity to public and private utilities, and it plays a crucial role in supporting the reliability of the region's power grid.
In addition to its transmission and marketing activities, BPA also conducts research and development on renewable energy technologies and energy efficiency, and it provides technical assistance to utilities and other customers. BPA's mission is to provide reliable, low-cost power to the Pacific Northwest while also promoting the development of renewable energy sources.
