Biomass and waste power plants in the United States
Biomass and waste units in the 2025 EIA-860 data total 12.5 GW of nameplate capacity, 0.9% of the US fleet. It is the main source at 584 plants; Florida has the most, with 1,144 MW. More of today’s biomass and waste capacity came online in 2013 than in any other year (761 MW). The oldest unit still working went into service in 1938 at Humboldt Sawmill Company, California.
When today’s biomass and waste capacity was built
Above the line: capacity still operable in 2025, by the year each unit came online. Below: biomass and waste capacity retired in each year, including plants that have closed completely (EIA’s retired-generator file).
