67th largest plant in Washington · 3300th nationally
Nippon Dynawave Packaging Longview Wa is a biomass power plant in Washington with a nameplate capacity of 62.4 MW. It generates roughly 289.0k MWh per year — enough to power about 27,523 average U.S. homes.
Its capacity factor of 53% puts it in the middle range — running steadily but not full-time. At 250 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 (62.4 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.
