How we generate and purchase power is as important to our members as the transmission lines that deliver electricity.

Tri-State is able to meet its members’ needs by deploying an efficient arsenal of owned-generation resources, long-term power purchase contracts and market purchases.

Our diverse generation portfolio leverages the West’s plentiful natural resources to generate reliable and affordable electricity for our membership. We manage risks and costs of power generation using base load-serving, coal generating units, intermediate load-serving natural gas, combined-cycle generating units and peak load-serving natural gas and oil combustion turbines.

To manage the costs of fuel supply, we use coal from Tri-State-owned mines and contract for other coal supplies through our cooperative network.

Renewable energy is a growing part of our portfolio, with Tri-State and member projects forecasted to produce 30 percent of the energy used by our association members in 2017.
