40th largest plant in Illinois · 960th nationally
Archer Daniels Midland Decatur is a coal power plant in Illinois with a nameplate capacity of 335 MW. It generates roughly 885.9k MWh per year — enough to power about 84,370 average U.S. homes.
Its capacity factor of 30% reflects intermittent or peaking operation.
Ghost bars are each month's theoretical maximum (335 MW nameplate × hours in the month). Filled bars are actual net generation reported to EIA Form 923. The gap between them is capacity factor made visible.

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.
