4th largest plant in Wyoming · 496th nationally
Naughton is a coal power plant in Wyoming with a nameplate capacity of 707 MW. It generates roughly 2.8M MWh per year — enough to power about 263,495 average U.S. homes.
Its capacity factor of 45% puts it in the middle range — running steadily but not full-time. At 2098 lb CO₂/MWh, its emission rate sits above the national grid average of roughly 800 lb/MWh.
Ghost bars are each month's theoretical maximum (707 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.
