There are numerous reasons the cooperative G&T model lives on today.

Our Members
We are a cooperative of 45 members, including 42 electric distribution cooperatives and public power districts in four states that together provide power to more than a million electricity consumers across nearly 200,000 square miles of the West. Our footprint is 20% larger than the state of California.
