Rushmore Electric is the wholesale power provider for eight rural electric cooperatives in western and central South Dakota. Rushmore Electric buys the bulk of its power from Basin Electric Power Cooperative who operates coal-fired plants, natural gas plants, renewable energy facilities, and a nuclear plant in Wyoming, Iowa, Montana, South Dakota, and North Dakota. About a sixth of its power comes from Western Area Power Administration, the federal marketer of low-cost hydroelectric power from the dams on the Missouri River. Rushmore Electric also provides a communications and control system for real-time monitoring of the electrical system. The Rapid City-based company also provides a variety of services to co-ops and agencies through its Rushmore Engineering and Rushmore Communications businesses. Rushmore Electric also provides contract labor and facilities to Rushmore Electric Federal Credit Union, who provides credit union services to electric cooperative employees in western South Dakota and Northeastern Wyoming.
