It accounts for about 32% of South Carolina's operating Hydro capacity and 4.5% of all operating capacity in the state. Nationally it is the 15th-largest of the 1,243 operating Hydro plants in the database. Commissioned in 1991, it is newer than 57% of the 82 operating South Carolina plants with a recorded commissioning year. Its operator, DUKE ENERGY CAROLINAS, LLC, runs 15 operating plants in South Carolina totaling 8,471 MW. It shares Oconee County with 3 other operating plants, including OCONEE and SENECA CITY OF.

EIA-860 lists 4 generators at the site with 1,680 MW of nameplate capacity, all hydroelectric pumped storage technology (this page's HIFLD capacity figure is 1,065 MW). The plant was a net consumer of electricity in 2024 (-545 GWh), which is typical of pumped storage.
