The Nussdorf power plant was built between 1979 and 1982. Two Kaplan turbines generate an annual average of around 246 GWh of electricity and supply the region with electricity produced entirely from hydropower.
Turbines and generators: The Nußdorf power plant is designed as a pier power plant, with three weir fields and two turbine piers arranged in alternation along the longitudinal axis. Each of the turbine piers houses an Kaplan turbine with vertical shaft and an umbrella generator with a total bottleneck capacity of 48 MW.

Weir system: The weir openings are closed by pressure segment gates with flap; they are operated by oil-hydraulic lift cylinders. The power plant belongs to the “border power plants” group, which is noted for its geographical location on the rivers Inn and Danube, where they form the border between Austria and Bavaria.
