Tri-State is well positioned to maintain a comparatively low-cost, reliable supply of electricity to its 43 member systems for the foreseeable future. Like most major power suppliers, Tri-State focuses on both the present and future power requirements of its members that ultimately deliver the power to end-use consumers. The association has added new energy resources to its generation mix in the past few years and more are being planned or currently under construction.
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 G&T owns and operates plants in Colorado and New Mexico, and it receives a share of power from plants in Arizona, New Mexico and Wyoming.
