Wehr is a 910 MW hydro power station in Baden-Wuerttemberg, Germany. It is operated by Schluchseewerk Aktiengesellschaft. Based on reported annual generation of 1,194 GWh, it can supply roughly 341,114 homes. It ranks #30 of 1,369 Germany power plants by installed capacity. Commissioned in 1975, it is around 51 years old — an older, legacy facility. As a non-combustion source, it has no direct CO₂ emissions from generation. In context, hydro supplies about 3.9% of Germany's electricity; the national grid averages 330 gCO₂/kWh (59.1% low-carbon) (2025).

This hydro plant converts the energy of falling or flowing water through hydro turbines. It sits in a temperate oceanic climate (Köppen Cfb) — Northern Hemisphere, latitude 47.6°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 41% 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.
