WAPA is one of four power marketing administrations within the U.S. Department of Energy whose role is to market and transmit wholesale electricity from multi-use water projects. Our service area encompasses a 15-state region of the central and western U.S. where our more than 17,000 circuit mile transmission system carries electricity from 56 hydro power plants operated by the Bureau of Reclamation, U.S. Army Corps of Engineers  and the International Boundary and Water Commission. We also market power from the Navajo Generating Station coal-fired plant near Page, Ariz. Together, these plants have an installed capacity of 10,504 megawatts. We sell our power to preference customers such as Federal and state agencies, cities and towns, rural electric cooperatives, public utility districts, irrigation districts and Native American tribes. They, in turn, provide retail electric service to millions of consumers in the West.
