Thomas Hill

⛏ CoalElectric Utility1,181 MW capacity

6th largest plant in Missouri · 247th nationally

Thomas Hill is a coal power plant in Missouri with a nameplate capacity of 1,182 MW. It generates roughly 5.9M MWh per year — enough to power about 565,489 average U.S. homes.

Its capacity factor of 57% puts it in the middle range — running steadily but not full-time. At 2200 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.
