77th largest plant in Oregon · 4854th nationally
Seneca Sustainable Energy Llc is a biomass power plant in Oregon with a nameplate capacity of 19.8 MW. It generates roughly 130.3k MWh per year — enough to power about 12,406 average U.S. homes.
Its capacity factor of 75% puts it in the middle range — running steadily but not full-time.
Ghost bars are each month's theoretical maximum (19.8 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.
