87th largest plant in Wisconsin · 4924th nationally
Packaging Of America Tomahawk Mill is a biomass power plant in Wisconsin with a nameplate capacity of 18.7 MW. It generates roughly 112.9k MWh per year — enough to power about 10,752 average U.S. homes.
Its capacity factor of 69% puts it in the middle range — running steadily but not full-time. At 284 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 (18.7 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.
