15th largest plant in Idaho · 2278th nationally
Clearwater Paper Ipp Lewiston is a biomass power plant in Idaho with a nameplate capacity of 114 MW. It generates roughly 383.1k MWh per year — enough to power about 36,482 average U.S. homes.
Its capacity factor of 38% reflects intermittent or peaking operation. At 150 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 (114 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.
