  • About

    Tri-State Generation and Transmission Association is a wholesale electric power supplier owned by the 44 electric cooperatives that it serves. Tri-State generates and transmits electricity to its member systems throughout a 200,000 square-mile service territory across Colorado, Nebraska, New Mexico and Wyoming.
    Serving approximately 1.5 million consumers, Tri-State was founded in 1952 by its member systems to provide a reliable, cost-based supply of electricity. Headquartered in Westminster, Colo., nearly 1,500 people are employed by Tri-State throughout its four-state service area.
    Tri-State’s power is generated through a combination of owned baseload and peaking power plants that use coal and natural gas as their primary fuels, supplemented by purchased power, federal hydroelectricity allocations and renewable resource technologies.
    Tri-State's mission is to provide our member systems a reliable, cost-based supply of electricity while maintaining a sound financial position through effective utilization of human, capital and physical resources in accordance with cooperative principles.
