How LOGAN MARTIN DAM compares
With 128 MW of capacity, LOGAN MARTIN DAM ranks 30th among the 64 operating power plants Bywatts maps in Alabama and 10th of the 23 operating Hydro plants in the state. It accounts for about 3.9% of Alabama's operating Hydro capacity and 0.4% of all operating capacity in the state. Nationally it is the 143rd-largest of the 1,243 operating Hydro plants in the database. Commissioned in 1964, it is older than 68% of the 64 operating Alabama plants with a recorded commissioning year. Its operator, ALABAMA POWER CO, runs 22 operating plants in Alabama totaling 12,989 MW. It shares Talladega County with 2 other operating plants, AMEA PEAKING and U S ALLIANCE COOSA PINES.
EIA-860 lists 3 generators at the site with 128 MW of nameplate capacity, all conventional hydroelectric technology. Net generation was 297 GWh in 2024 (a 26% capacity factor), down 28% from 2022.

Weather peril exposure
LOGAN MARTIN DAM is a 128 MW hydro power plant in Talladega County, AL, operated by ALABAMA POWER CO, commissioned in 1964. Talladega County carries moderate modeled catastrophe exposure in the FEMA National Risk Index, scoring 2.2 of 5 at the 31st national percentile. Tornado is the leading peril, rated Relatively High by FEMA at the 91st percentile.
The Bywatts loss layer is calibrated to solar PV hardware, so it is not applied to a hydro plant. The ratings below are the FEMA National Risk Index county hazard ratings for this location.
