BiomassMaineUnited States of America
Androscoggin Mill is a 80 MW biomass power plant in Maine, United States of America. It is operated by Verso Paper Androscoggin LLC. Based on reported annual generation of 387 GWh, it can supply roughly 110,657 homes. It ranks #2204 of 9,833 United States of America power plants by installed capacity. Commissioned in 1968, it is around 58 years old — an older, legacy facility. In context, biomass supplies about 1.0% of United States of America's electricity; the national grid averages 384 gCO₂/kWh (43.0% low-carbon) (2025).

This biomass plant burns organic material (wood, residues) to raise steam for a turbine. It sits in a warm-summer humid continental climate (Köppen Dfb) — Northern Hemisphere, latitude 44.5°N — which shapes how much energy it can produce and how its output varies through the year.
Monthly mean temperature
Heating degree-days here run 75% above the median power plant in this dataset — a proxy for how much extra energy heated equipment must replace through its surfaces in winter.
Climate heat-demand index: 88/100 — this site sits in the top third of the power plants we cover by heating degree-days.
In colder climates, uninsulated hot equipment (boilers, turbines, valves, steam lines) loses proportionally more heat to ambient air — exactly the loss Inzonex modular insulation is designed to cut.
