895th largest plant in California · 6505th nationally
Mm West Covina is a biomass power plant in California with a nameplate capacity of 6.8 MW. It generates roughly 39.9k MWh per year — enough to power about 3,803 average U.S. homes.
Its capacity factor of 67% puts it in the middle range — running steadily but not full-time. At 14 lb CO₂/MWh, its emission rate sits below the national grid average of roughly 800 lb/MWh.
Ghost bars are each month's theoretical maximum (6.8 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.

Biomass plants burn wood, agricultural waste, or methane from landfills to generate steam and electricity. They are considered carbon-neutral over long timescales when fuel is sustainably sourced, but they produce particulate emissions similar to coal.
