91st largest plant in Oregon · 5315th nationally
Covanta Marion Inc is a biomass power plant in Oregon with a nameplate capacity of 13.1 MW. It generates roughly 48.8k MWh per year — enough to power about 4,648 average U.S. homes.
Its capacity factor of 43% puts it in the middle range — running steadily but not full-time. At 2392 lb CO₂/MWh, its emission rate sits above the national grid average of roughly 800 lb/MWh.
Ghost bars are each month's theoretical maximum (13.1 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.
