Western Area Power Administration

From Wikipedia, the free encyclopedia

The Western Area Power Administration (Western) markets and delivers hydroelectric power and related services within a 15-state region of the central and western U.S. It is one of four power marketing administrations within the U.S. Department of Energy whose role is to market and transmit electricity from multi-use water projects. Its transmission system carries electricity from 55 hydropower plants operated by the Bureau of Reclamation, U.S. Army Corps of Engineers and the International Boundary and Water Commission. Together, these plants have a capacity of 10,600 megawatts. Western is headquartered in the Denver suburb of Lakewood, Colorado.

Western built several parts of the important Path 15 corridor which connects power grids in the Southwest and Pacific Northwest (the rest was built by PG&E). Recently, Western helped remedy a transmission bottleneck near Los Banos, California. That bottleneck was one of the reasons for the California electricity crisis in 2000-01. Another important transmission corridor Western built was Path 66, paralleling Path 15.

Western and its energy-producing partners are separately managed and financed. In addition, each water project maintains a separate financial system and records.
