552nd largest plant in California · 4240th nationally
Wadham Energy Lp is a biomass power plant in California with a nameplate capacity of 29.1 MW. It generates roughly 74.4k MWh per year — enough to power about 7,089 average U.S. homes.
Its capacity factor of 29% reflects intermittent or peaking operation. At 22 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 (29.1 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.

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.
