VERBUND's Schärding-Neuhaus plant is a run-of-river power plant on the Inn River in the municipalities of Schärding in Upper Austria and Neuhaus in Bavaria.
The Schärding-Neuhaus power plant was built between 1959 and 1961 as the second power plant of the “border power plants” group. The power plant group is noted for its geographical location on the Inn and Danube, where they form the border between Austria and Bavaria. Installed in the power plant are four Kaplan turbines which generate around 542 GWh of electricity per year and supply the region with valuable hydropower.
Owner: Österreichisch-Bayerische Kraftwerke AG
Operator: Grenzkraftwerke GmbH
Commissioning: 1966
Type: Run-of-river power plant
Country: Austria
Region: Bavaria, Upper Austria
Waters: Inn
Output: 96 MW
Annual output: 541,800 MWh
Turbine: Kaplan
Connectivity: No fish bypass
Four Kaplan turbines with vertical shaft and a maximum output of 96 MW are combined with four directly coupled three-phase synchronous generators with a nominal output of 30 MVA.
The electricity generated is raised from 10.5 kV to 220 kV by means of two high-voltage main transformers and fed into the public grid via a loop into the Jochenstein - St. Peter line.
Five weir fields with a clear width of 23 metres each are equipped with double hook gates with a closing height of 13.7 metres each. Because of the similar hydraulic conditions, the entire weir system was constructed identically to the one at Braunau-Simbach. The gates are operated by weir chains powered by electric motors.

The construction of a fish bypass at the Schärding-Neuhaus power plant is currently being planned.
The construction of the power plant and the reservoir area has created unique, new habitats for flora and fauna with the waterbody and the newly created siltation areas. On the Austrian and Bavarian sides, an extensive bird paradise was created between Reichersberg, the Antiesen mouth and Bad Füssing. Rare species of bird, such as night heron, purple heron, little bittern and pintail duck have found a new home here. Compared to the years before the power plant’s construction, many more breeding birds and migratory birds populate the reservoir area today.
