Power Plants in Alabama

Alabama has 33.1 gigawatts of nameplate capacity across 81 plants, ranking 14th among the 50 states and DC. This is capacity — what the equipment could produce running flat out — not the actual generation these plants produce, which varies widely by fuel type over the course of a year.

Natural gas dominates the fleet at 59.1% of capacity across 25 plants, followed by nuclear at 17% from just 2 plants. Hydro provides 10% across 23 plants, coal 8.5% from a single plant, and solar 3% from 15 plants, with other sources making up the remaining 2.4%. The largest plant is Browns Ferry, a nuclear facility with 3,854 megawatts, followed by Barry, a natural gas plant with 3,344 megawatts; James H Miller Jr, the coal plant, adds 2,822 megawatts. Two major natural gas installations, E C Gaston at 2,034 megawatts and H Allen Franklin Combined Cycle at 1,996 megawatts, round out the five largest.

The fleet spans more than a century, from Goat Rock, which came online in December 1915, to Old Hayneville Solar, LLC, which entered service in August 2026.
