Escanaba Mill

Biomass power plant in Michigan, United States of America. Approximate location 45.8044, -87.0891.

BiomassMichiganUnited States of AmericaCO₂ reported

Escanaba Mill is a 122 MW biomass power station in Michigan, United States of America. It is operated by Verso Escanaba LLC. Based on reported annual generation of 491 GWh, it can supply roughly 140,342 homes. It ranks #1711 of 9,833 United States of America power plants by installed capacity. Commissioned in 1975, it is around 51 years old — an older, legacy facility. Its measured emissions of 49,485 t CO₂/yr (Climate TRACE) are equivalent to about 11,535 cars driven for a year. 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).

Local climate & thermal context

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 45.8°N — which shapes how much energy it can produce and how its output varies through the year.

Heating degree-days here run 81% 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: 90/100 — 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.
