GENERAL JAMES M GAVIN, a 2,600 MW Coal power plant in Gallia County, Ohio. Operated by OHIO POWER CO, commissioned 1974.
How GENERAL JAMES M GAVIN compares
With 2,600 MW of capacity, GENERAL JAMES M GAVIN is the largest of the 102 operating power plants Bywatts maps in Ohio and the largest of the 14 operating Coal plants in the state. It accounts for about 35% of Ohio's operating Coal capacity and 12% of all operating capacity in the state. Nationally it is the 12th-largest of the 324 operating Coal plants in the database. Commissioned in 1974, it is older than 73% of the 99 operating Ohio plants with a recorded commissioning year. Its operator, OHIO POWER CO, runs 4 operating plants in Ohio totaling 4,133 MW. It shares Gallia County with one other operating plant, KYGER CREEK.
EIA-860 lists 2 generators at the site with 2,600 MW of nameplate capacity, all conventional steam coal technology. Net generation was 10,326 GWh in 2024 (a 45% capacity factor), down 14% from 2022. Its generators came online between 1974 and 1975.

Weather peril exposure
GENERAL JAMES M GAVIN is a 2,600 MW coal power plant in Gallia County, OH, operated by OHIO POWER CO, commissioned in 1974. Gallia County carries low modeled catastrophe exposure in the FEMA National Risk Index, scoring 1.8 of 5 at the 19th national percentile. Riverine flooding is the leading peril, rated Relatively Low by FEMA at the 80th percentile.
The Bywatts loss layer is calibrated to solar PV hardware, so it is not applied to a coal plant. The ratings below are the FEMA National Risk Index county hazard ratings for this location.
