Rosenthal Mill power station is a 57 MW biomass power plant in Thuringia, Germany. It is operated by Mercer International Inc. Based on its capacity (estimated), it can supply roughly 78,464 homes (estimated). It ranks #272 of 1,369 Germany power plants by installed capacity. In context, biomass supplies about 10.1% of Germany's electricity; the national grid averages 330 gCO₂/kWh (59.1% low-carbon) (2025).

This biomass plant burns organic material (wood, residues) to raise steam for a turbine. It sits in a temperate oceanic climate (Köppen Cfb) — Northern Hemisphere, latitude 50.4°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 68% 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: 86/100 — 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.
