French Island

🌿 BiomassElectric Utility188 MW capacity

26th largest plant in Wisconsin · 1643rd nationally

French Island is a biomass power plant in Wisconsin with a nameplate capacity of 188 MW. It generates roughly 62.2k MWh per year — enough to power about 5,921 average U.S. homes.

Its capacity factor of 4% reflects intermittent or peaking operation. At 1120 lb CO₂/MWh, its emission rate sits above the national grid average of roughly 800 lb/MWh.

About Biomass plants

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.
