AVISE is a 126 MW hydro power station in Aosta Valley, Italy. Based on reported annual generation of 258 GWh, it can supply roughly 73,571 homes. It ranks #114 of 441 Italy power plants by installed capacity. As a non-combustion source, it has no direct CO₂ emissions from generation. In context, hydro supplies about 15.8% of Italy's electricity; the national grid averages 285 gCO₂/kWh (48.8% 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 45.7°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 170% 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: 99/100 — 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 #31 largest hydro power plant of 58 in Italy by capacity.
Italy has 58 hydro power plants in this dataset, together about 13,384 MW of capacity.
