| Purpose | The Roza Powerplant provides power at the cost of production to operate pumps on the Roza Irrigation District. The Roza Irrigation District pumps to 27,700 acres of their irrigation deliveries. Any other power generated is marketed through the BPA. |
| Facts | The Roza Powerplant develops 12,937 kilowatts. More than 70 miles of transmission lines deliver power to pumping plants in the Roza Division. |
| History | Plans for the Roza Division were initiated in 1932. The powerplant was completed in conjunction with that plan in 1958. It has been operated since at the maximum capacity allowed by available flows, weather, and maintenance. |
| Present Activities | Normal operations |
| Special Issues | A major contributor to the cost of O&M at the Roza Powerplant is the cost of maintaining about 10 miles of delivery canal and over 70 miles of transmission line. |
