In the Pankrazer Stausee (also Pankrazer See or Italian Lago di Alborelo ) the Falschauer in the Ultental in South Tyrol is dammed about 2.5 km above St. Pankraz . The reservoir lies at an altitude of 809 m and is the second largest in the Ulten Valley after the Zoggler reservoir .
It is part of the chain of reservoirs and hydropower plants in the Ulten Valley that Alperia Greenpower GmbH operates for the electrical energy use of the valley's hydropower. It is the deepest of the reservoirs and was the first to be built. After four years of construction, it was put into operation in 1954. It supplies the Lana power station with its water .
The lake's slightly curved reinforced concrete gravity dam, fitted into the valley at a narrow point, is 58 meters high and 119 meters long at the top. The lake is 800 meters long and 200 meters at its widest point. It covers about 12.5 hectares and its capacity is three million cubic meters.
The water of the lake, a maximum of 26 m³ / s, flows through a pressure tunnel and a pressure pipe 2.5 meters in diameter and 6.8 kilometers in length over a drop of 478 meters to the turbines of the Lana power plant. These generate a maximum electrical output of 120 MW.
At the far end of the lake is the St. Pankraz power station , which is not operated by the Pankraz reservoir, but by the next higher lake, the Zoggler reservoir. The runoff water from this power plant is a major inflow to the Pankraz reservoir.
