Democratic Member Control
These founding principles still hold true today, over 70 years later. Our members chose to band together to bring electricity to rural areas where there was no financial incentive for large investor-owned utilities to build. They all pitched in to pay for infrastructure across rugged terrain and share risks that no rural electric utility could bear on its own. There are numerous reasons the cooperative G&T model lives on today.

That was the thought behind Tri-State Generation and Transmission when we were formed more than 70 years ago, and that remains the idea today.
