70th largest plant in Washington · 3411th nationally
Kettle Falls Generating Station is a biomass power plant in Washington with a nameplate capacity of 57.9 MW. It generates roughly 335.1k MWh per year — enough to power about 31,913 average U.S. homes.
Its capacity factor of 66% puts it in the middle range — running steadily but not full-time. At 111 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 (57.9 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.
