About Us

Tri-State began as a not-for-profit association of electric co-ops in 1952 with the goal of providing electricity to rural homes, businesses and farms across the West—and that’s still what drives us today.

Powering the Future

At Tri-State G&T, reliability is more than a promise—it’s our mission. Comprehensive planning, year-round wildfire mitigation, transmission upgrades and more ensure our members will have the power they need today, tomorrow, and for generations to come.

Electrify and Save®

Electricity is becoming cleaner and more renewable every day. Going electric can lower your monthly energy bills, help the environment and improve the quality of life in local communities.

We are a not-for-profit power supplier to cooperatives and public power districts in four states that together deliver reliable, affordable and responsible power to more than a million electricity consumers across nearly 200,000 square miles of the West.

Operations

It’s a big job to deliver reliable power to communities across nearly 200,000 square miles of the West, from the high plains to the desert southwest, and from the black hills of Wyoming to the peaks of Colorado.
