The order is scheduled to be completed by the beginning of 2023.

Tulsa District operates and maintains eight hydroelectric power plants, containing a total of 22 units with a generating capacity of 584 MW. Seven of the plants are located within eastern Oklahoma with one located just across the border in Texas. These plants benefit approximately 2 million end users throughout Oklahoma.
