Werkskraftwerk Sappi Alfeld 1 is a 17 MW biomass power plant in Lower Saxony, Germany. It is operated by Sappi Alfeld GmbH. Based on its capacity (estimated), it can supply roughly 23,126 homes (estimated). It ranks #573 of 1,369 Germany power plants by installed capacity. Commissioned in 1988, it is around 38 years old — long-established. Its measured emissions of 31,353 t CO₂/yr (Climate TRACE) are equivalent to about 7,308 cars driven for a year. 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 52.0°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 40% 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: 75/100 — 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.

The #47 largest biomass power plant of 72 in Germany by capacity.
Germany has 72 biomass power plants in this dataset, together about 2,427 MW of capacity.
