| Project Detail |
The 36.4-MW Red Rock hydroelectric plant is being built at an existing dam on the Des Moines River in Iowa, U.S. The powerhouse will be located downstream from the U.S. Army Corps of Engineers’ Red Rock Dam and contain two Kaplan turbine-generator units fed by an intake structure upstream from the dam. This rolled earthfill embankment dam with a gravity concrete control section is 5,200 feet long and 95 feet high above the flood plain and was built in the 1960s to provide flood control. The plant is expected to produce enough electricity to power about 18,000 homes each year. This will be the first hydro facility Missouri River Energy Services develops.
