Jocassee Pumped Hydro Storage
The four-unit Jocassee Hydroelectric Station is a 710-megawatt pumped-storage generating facility located in Pickens County, S.C. The facility works much like a conventional hydroelectric station, except that it can reverse turbines and pump back previously used water from a lower lake to store potential energy for later.
The Jocassee facility typically generates power during times of peak electric demand. In the Carolinas, peaks are usually on hot summer afternoons and cold winter mornings during the work week. Water power uses no fuel in the generation of electricity and so has very low operating costs.
