35th largest plant in Utah · 3405th nationally
Sunnyside Cogen Associates is a coal power plant in Utah with a nameplate capacity of 58.1 MW. It generates roughly 316.5k MWh per year — enough to power about 30,143 average U.S. homes.
Its capacity factor of 62% puts it in the middle range — running steadily but not full-time.
Ghost bars are each month's theoretical maximum (58.1 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.
