How JONES BLUFF compares
With 82 MW of capacity, JONES BLUFF ranks 43rd among the 64 operating power plants Bywatts maps in Alabama and 16th of the 23 operating Hydro plants in the state. It accounts for about 2.5% of Alabama's operating Hydro capacity and 0.3% of all operating capacity in the state. Nationally it is the 207th-largest of the 1,243 operating Hydro plants in the database. Commissioned in 1975, it is newer than 50% of the 64 operating Alabama plants with a recorded commissioning year. Its operator, USCE-MOBILE DISTRICT, runs 2 operating plants in Alabama totaling 183 MW. It shares Autauga County with 4 other operating plants, including E B HARRIS ELECTRIC GENERATING PLANT and TENASKA LINDSAY HILL GENERATING STATION.
EIA-860 lists 4 generators at the site with 82 MW of nameplate capacity, all conventional hydroelectric technology. Net generation was 244 GWh in 2024 (a 34% capacity factor), down 12% from 2022.
