The Secchione hydro plant is located in Chiesa in Valmalenco. It benefits from an altitude difference of 420 meters and comes from a basin surrounded by peaks and mountains over 3000 meters high. The generator consists of a horizontal axis Pelton turbine with an output of 1,8 Mw. The plant produces 4.500.000 Kwh.


The Vaniga hydro plant, situated in the Valvarrone valley, has an output capacity of 600 Kwh. The electricity is generated by 2 Pelton groups on vertical axis able to optimize the production of the plant due to high streamflow variability. With respect to environmental flow regimes, it can get up to a maximum flow of …
