GKM (Mannheim) power station is a 1,958 MW coal power station in Rheinland-Pfalz, Germany. It is operated by Grosskraftwerk Mannheim. Based on its capacity (estimated), it can supply roughly 2,450,297 homes (estimated). It ranks #8 of 1,369 Germany power plants by installed capacity. Commissioned in 1980, it is around 46 years old — long-established. Its measured emissions of 3,192,820 t CO₂/yr (Climate TRACE) are equivalent to about 744,247 cars driven for a year. In context, coal supplies about 20.6% of Germany's electricity; the national grid averages 330 gCO₂/kWh (59.1% low-carbon) (2025).

This coal plant burns coal to raise high-pressure steam that spins a turbine-generator. It sits in a temperate oceanic climate (Köppen Cfb) — Northern Hemisphere, latitude 49.4°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 12% 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: 56/100 — this site sits in the mid 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 #6 largest coal power plant of 98 in Germany by capacity.
Germany has 98 coal power plants in this dataset, together about 49,623 MW of capacity.
