in 1937 to market electric power from the Bonneville Dam located on the Columbia River and to construct facilities necessary to transmit that power. Congress has since designated Bonneville to be the marketing agent for power from all of the federally owned hydroelectric projects in the Pacific Northwest. Bonneville is one of four regional Federal power marketing agencies within the U.S. Department of Energy (DOE).

Together these three lines are operated as the California-Oregon Intertie (COI) (managed by the California Independent System Operator CAISO).

History

BPA's first industrial sale was to Alcoa in January 1940, to provide 32,500 kilowatts of power. This, and the following 162,500 kilowatt order, led to complaints of the Bonneville Power Act's anti-monopoly clause. The cheap price of aluminum from Alcoa helped aluminum sales grow in the post-

market. Overly optimistic estimates of future electricity consumption by BPA in the 1960s led the agency to guarantee some bonds for the disastrous Washington Public Power Supply System nuclear power project. Out of five nuclear power plants started ( WNP-1 and WNP-4, WNP-3 and WNP-5), only WNP-2 was completed. BPA is still making payments on three of the abandoned plants. In 2003, BPA's debt for the nuclear project totaled $6.2 billion. In 1973,
