Avise power plant

The Avise hydroelectric power plant is a plant of national importance, included in the power grid restart plan in the event of a total blackout. It is capable of feeding power into the 220,000 V grid without the use of external power sources.

Avise is a reservoir hydroelectric plant that utilizes the energy of water from the upper Dora di Valgrisenche. The annual renewable energy production that the power plant achieves from its three Pelton turbine-powered units - with a total capacity of 126 MW and a maximum flow rate of 16.5 m3/second - is more than 285 GWh.
The engine room dating from 1954, designed by architect Giovanni Muzio, carved out of a cave and reached through a tunnel about seven hundred meters long, is adorned with a large fresco depicting the twelve signs of the zodiac.

The cavern, which houses both hydropower units and voltage step-up transformers to vector the renewable electricity produced outside, could contain a ten-story building because of its size.
