reated in 1937 by Congress and The Roosevelt Administration, The Bonneville Power Administration (BPA) is a federal, U.S. Department of Energy agency that markets wholesale electrical power and transmission services in the Pacific Northwest.
While it is a federal agency, BPA is not tax-supported through government appropriations. BPA recovers all of its costs through their electricity and transmission sales. Sources of this power include 30 federal hydro projects, 1 non-federal nuclear plant, and other non-federal power plants. This system is referred to as The Federal Columbia River Power System. Almost half of the power used in the Northwest comes from BPA. We receive approximately 2/3 of our power supply from BPA.
