BiomassAlabamaUnited States of America
WestRock Demopolis Mill is a 47 MW biomass power plant in Alabama, United States of America. It is operated by WestRock Mill Company LLC. Based on reported annual generation of 297 GWh, it can supply roughly 84,742 homes. It ranks #2834 of 9,833 United States of America power plants by installed capacity. Commissioned in 2005, it is around 21 years old — relatively modern. 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 humid subtropical climate (Köppen Cfa) — Northern Hemisphere, latitude 32.5°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 52% below 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: 29/100 — this site sits in the bottom 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.
