We power possibilities across 30,000 square miles of the Sooner State - from Elk City to Chickasha and Atoka to Vinita.

Proudly headquartered in Tulsa, our network of transmission lines form part of our parent company American Electric Power's service territory, which spans 11 states across America's heartland.
