Fernandina Beach Mill

🌿 BiomassIndustrial CHP96 MW capacity

65th largest plant in Florida · 2631st nationally

Fernandina Beach Mill is a biomass power plant in Florida with a nameplate capacity of 96.9 MW. It generates roughly 557.7k MWh per year — enough to power about 53,116 average U.S. homes.

Its capacity factor of 66% puts it in the middle range — running steadily but not full-time. At 207 lb CO₂/MWh, its emission rate sits below 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.
