512th largest plant in California · 4035th nationally
Brea Expansion Plant is a biomass power plant in California with a nameplate capacity of 35.7 MW. It generates roughly 247.0k MWh per year — enough to power about 23,525 average U.S. homes.
Its capacity factor of 79% puts it in the middle range — running steadily but not full-time.
Ghost bars are each month's theoretical maximum (35.7 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.
