COLBERT, a 1,826 MW Coal power plant in Colbert County, Alabama. Operated by TENNESSEE VALLEY AUTHORITY, commissioned 1972.
How COLBERT compares
With 1,826 MW of capacity, COLBERT ranks 6th among the 64 operating power plants Bywatts maps in Alabama and 4th of the 7 operating Coal plants in the state. It accounts for about 16% of Alabama's operating Coal capacity and 5.8% of all operating capacity in the state. Nationally it is the 43rd-largest of the 324 operating Coal plants in the database. Commissioned in 1972, it is older than 51% of the 64 operating Alabama plants with a recorded commissioning year. Its operator, TENNESSEE VALLEY AUTHORITY, runs 7 operating plants in Alabama totaling 6,524 MW.
Under the same EIA plant code, EIA-860 lists 11 generators at the site with 1,170 MW of nameplate capacity (this page's HIFLD capacity figure is 1,826 MW). Net generation was 321 GWh in 2024 (a 3.1% capacity factor). Its generators came online between 1972 and 2023.
Grid neighborhood
The nearest named substation is CHEROKEE (161 kV), about 0.1 miles away; the closest transmission line found within 10 miles is a 161 kV line owned by TENNESSEE VALLEY AUTHORITY, under 0.1 miles away. One other operating power plant sits within 25 miles: WILSON DAM (667 MW, Hydro).

Weather peril exposure
COLBERT is a 1,826 MW coal power plant in Colbert County, AL, operated by TENNESSEE VALLEY AUTHORITY, commissioned in 1972. Colbert County carries moderate modeled catastrophe exposure in the FEMA National Risk Index, scoring 2.0 of 5 at the 25th national percentile. Strong wind is the leading peril, rated Relatively High by FEMA at the 90th 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.
