Kaprun Oberstufe is a 113 MW hydro power station in Salzburg, Austria. It is operated by Verbund. Based on reported annual generation of 227 GWh, it can supply roughly 64,828 homes. It ranks #33 of 118 Austria power plants by installed capacity. Commissioned in 1956, it is around 70 years old — an older, legacy facility. As a non-combustion source, it has no direct CO₂ emissions from generation. In context, hydro supplies about 51.8% of Austria's electricity; the national grid averages 117 gCO₂/kWh (83.6% low-carbon) (2025).

This hydro plant converts the energy of falling or flowing water through hydro turbines. It sits in a polar tundra climate (Köppen ET) — Northern Hemisphere, latitude 47.2°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 193% 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: 100/100 — 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 #26 largest hydro power plant of 96 in Austria by capacity.
Austria has 96 hydro power plants in this dataset, together about 9,072 MW of capacity.
