1st largest plant in Utah · 136th nationally
Intermountain Power Project is a coal power plant in Utah with a nameplate capacity of 1,640 MW. It generates roughly 4.4M MWh per year — enough to power about 423,702 average U.S. homes.
Its capacity factor of 31% reflects intermittent or peaking operation. At 2169 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 (1,640 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.
