Grohnde is a 1,360 MW nuclear power station in Lower Saxony, Germany. It is operated by E.ON Kernkraft GmbH. Based on reported annual generation of 9,133 GWh, it can supply roughly 2,609,485 homes. It ranks #21 of 1,369 Germany power plants by installed capacity. Commissioned in 1985, it is around 41 years old — long-established. As a non-combustion source, it has no direct CO₂ emissions from generation. In context, nuclear supplies about 0.0% of Germany's electricity; the national grid averages 330 gCO₂/kWh (59.1% low-carbon) (2025).

This nuclear plant uses heat from nuclear fission to raise steam for a turbine-generator. 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 38% 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: 73/100 — 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.
