| River | Trans Mountain Diversion |
| Purpose | Green Springs Powerplant was constructed to take advantage of the head drop of the transbasin diversion to produce power for commercial sales to assist repayment of the division costs. |
| Facts | The Green Springs tunnel and power conduit are 6,650 feet long and connect to the penstock, which is 60 inches in diameter and 9,000 feet long. The Green Springs Powerplant is an outdoor-type plant with a capacity of 16,000 kilowatts and a discharge of 133 cubic feet per second operating under a head of 1,800 feet. The powerplant is generally manned on a two-shift basis. |
| History | The Green Springs Powerplant was placed in service in 1960 and has helped meet expanding power demands in southern Oregon and northern California. Revenues have contributed significantly to the repayment of construction costs of the Talent Division. The generator was rewound and the switchyard rehabilitated in 1993. |
| Present Activities | Normal operations |
| Future Planned Activities | Generator Field Poles will be rebuilt in Spring 2004. Unit Transformer replacement and Switchyard Mods. will be done in Fall 2005. |
