HAGOOD, a 186 MW Natural Gas power plant in Charleston County, South Carolina. Operated by SOUTH CAROLINA ELECTRIC&GAS CO, commissioned 1991.

How HAGOOD compares

With 186 MW of capacity, HAGOOD ranks 25th among the 83 operating power plants Bywatts maps in South Carolina and 8th of the 12 operating Natural Gas plants in the state. It accounts for about 3.1% of South Carolina's operating Natural Gas capacity and 0.8% of all operating capacity in the state. Nationally it is the 552nd-largest of the 1,185 operating Natural Gas 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, SOUTH CAROLINA ELECTRIC&GAS CO, runs 12 operating plants in South Carolina totaling 5,236 MW.

EIA-860 lists 3 generators at the site with 177 MW of nameplate capacity, all natural gas fired combustion turbine technology. Net generation was 17.9 GWh in 2024 (a 1.2% capacity factor). Its generators came online between 1991 and 2010.
