Tri State Generation & Transmission Association Inc


The Tri-State Generation and Transmission Association is a wholesale electric power supplier owned by the 44 electric cooperatives that it serves. The company generates and transports electricity to its member systems throughout a 250,000 square-mile service territory across Colorado, Nebraska, New Mexico and Wyoming. Tri-State was founded in 1952 by its member systems and began with the mission of providing a reliable, cost-based supply of electricity. It is headquartered in Westminster, and employs more than 1,000 people throughout its four-state service area.  

The power- generation is done through a combination of owned base load 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; since Tri-StateÂâ€Ã¢„¢s mission is to provide member owners 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.  

Tri-State's owned and contracted portfolio of electric energy is derived from coal, natural gas and oil-fired and combustion turbine generation facilities located throughout its four-state member service territory. The association purchases federal hydropower from the Western Area Power Administration, which accounted for 15 percent of its energy in 2004 and it also purchases energy from renewable energy sources such as wind power, small hydropower and biomass. Tri-State owns (wholly or jointly) or has maintenance responsibilities for over 5,100 miles of transmission line across Colorado, Nebraska, New Mexico and Wyoming.  

The electricity that Tri-State generates at its coal-fired power plants comes from clean-burning, high-quality, low-sulfur coal. The latest in environmental controls have been installed and are in operation at all Tri-State plants, allowing the facilities to meet or exceed federal and state clean-air standards. The company has designed its power system to operate and remain environmentally sound, while meeting present and future electricity needs- truly in keeping with Tri-State's commitment to a healthy environment.
