HARTWELL ENERGY FACILITY, a 360 MW Natural Gas power plant in Hart County, Georgia. Operated by OGLETHORPE POWER CORPORATION, commissioned 1994.
How HARTWELL ENERGY FACILITY compares
With 360 MW of capacity, HARTWELL ENERGY FACILITY ranks 30th among the 104 operating power plants Bywatts maps in Georgia and 19th of the 26 operating Natural Gas plants in the state. It accounts for about 2.4% of Georgia's operating Natural Gas capacity and 1.0% of all operating capacity in the state. Nationally it is the 405th-largest of the 1,185 operating Natural Gas plants in the database. Commissioned in 1994, it is newer than 61% of the 101 operating Georgia plants with a recorded commissioning year. Its operator, OGLETHORPE POWER CORPORATION, runs 8 operating plants in Georgia totaling 4,973 MW. It shares Hart County with one other operating plant, HARTWELL LAKE.
EIA-860 lists 2 generators at the site with 360 MW of nameplate capacity, all natural gas fired combustion turbine technology. Net generation was 175 GWh in 2024 (a 5.5% capacity factor), down 40% from 2022.

Weather peril exposure
HARTWELL ENERGY FACILITY is a 360 MW natural gas power plant in Hart County, GA, operated by OGLETHORPE POWER CORPORATION, commissioned in 1994. Hart County carries moderate modeled catastrophe exposure in the FEMA National Risk Index, scoring 2.5 of 5 at the 38th national percentile. Lightning is the leading peril, rated Relatively Low by FEMA at the 90th percentile.
The Bywatts loss layer is calibrated to solar PV hardware, so it is not applied to a natural gas plant. The ratings below are the FEMA National Risk Index county hazard ratings for this location.
Hart County hazard ratings
