347th largest plant in California · 3296th nationally
Argus Cogen Plant is a coal power plant in California with a nameplate capacity of 62.5 MW. It generates roughly 244.8k MWh per year — enough to power about 23,315 average U.S. homes.
Its capacity factor of 45% puts it in the middle range — running steadily but not full-time. At 1133 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 (62.5 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.
