⛏ CoalElectric Utility2,822 MW capacity

3rd largest plant in Alabama · 18th nationally

James H Miller Jr is a coal power plant in Alabama with a nameplate capacity of 2,822 MW. It generates roughly 15.8M MWh per year — enough to power about 1,509,151 average U.S. homes.

Its capacity factor of 64% puts it in the middle range — running steadily but not full-time. At 2286 lb CO₂/MWh, its emission rate sits above the national grid average of roughly 800 lb/MWh.

About Coal plants

Coal plants burn pulverized coal to boil water and spin steam turbines. They emit substantial CO₂, SO₂, and NOₓ along with mercury and particulate matter. Modern units include scrubbers and selective catalytic reduction; older units are increasingly being retired or converted to natural gas as economics shift.
