Pressure line to the power house in Villa di Tirano

The Stazzona hydropower plant ( Italian : Centrale idroelettrica di Stazzona ) from A2A is located in the Italian municipality of Villa di Tirano in the Stazzona fraction in the province of Sondrio in Lombardy . It has an output of around 30  megawatts (installed output: 46.4 MW) and has two machine sets with Francis turbines and generators .

history

The Stazzona power plant originally belonged to the Azienda Elettrica Municipale di Milano (roughly: dt : Electrical Stadtwerke Milano ), whereby the whole power plant group originally comprised five main stages on the Adda and three lateral power plant stages, which were to be expanded much further.

The facility in Villa di Tirano was extensively renovated in the mid-1980s.

Use of hydropower

The plant is the last power plant in the power plant chain in Valtellina from the source of the Adda to Villa di Tirano. At the Stazzona power plant, A2A uses the water masses collected by a water intake of the Adda (Traversa di Sernio) and those discharged from the Lovero power plant (above Tirano near Sernio). The water to be processed is led by an 8.5 km long overpass to the underground cavern (394 m above sea level) in Villa di Tirano and then to the pressure pipelines and the power house. The processed water is then returned to the Adda . The total water catchment area for this power plant is around 990 km².
