Transmission

 

Our transmission lines span the West. Fundamental to our mission to serve our members across a vast service area is how we own our resources and physically connect loads, resources and markets. Tri-State’s transmission facilities are central to serving our members with reliable power across the expansive and diverse landscape of the West.

By owning a significant portion of the transmission system we use, we are able to quickly respond to the needs of our member systems, and in short time put new facilities and delivery points into service to reliably serve growing loads. We take a systems approach to building and operating our transmission network, ensuring that we can also access our generation resources and tap into broader energy markets.

Tri-State is part of a multi-state, interconnected transmission network and owns or operates 5,562 miles of high-voltage lines. An extensive network of substations, telecommunications and maintenance centers and field offices supports the system.
