Ering-Frauenstein Run-of-River Power Plant

The river Inn forms the border between Austria and Germany over a long distance. But hydropower plants can be connectors, such as the Ering-Frauenstein power plant, which builds a bridge for pedestrians between Bavaria and the Austrian Innviertel region.

Technical Description 

The Ering-Frauenstein power plant was built between 1938 and 1943. At the time it was the first power plant in the Lower Inn area; that is the area between the Salzach estuary and Passau. Three vertically built-in Kaplan turbines generate an average yearly output of 438 GWh. The publically accessible weir bridge was renovated in the years 2002 to 2003.
