VERBUND's power plant at Passau-Ingling is a run-of-river power plant situated on the Inn between the municipalities of Schardenberg (Upper Austria) and Passau (Bavaria).
The Passau-Ingling power plant was built between 1962 and 1965. Installed in the power plant are four Kaplan turbines which generate an annual average of around 505 GWh of electricity entirely from environmentally friendly hydropower.
The planned LIFE Blue Belt Danube Inn project aims at connecting precious habitats on the Inn and Danube with each other and improving the habitat conditions within the Natura 2000 areas. As part of the project, the Inn power plant Passau-Ingling is getting a modern fish pass.
Owner: Österreichisch-Bayerische Kraftwerke AG
Operator: Grenzkraftwerke GmbH
Commissioning: 1966
Type: Run-of-river power plant
Country: Austria, Germany
Region: Upper Austria, Bavaria
Waters: Inn
Output: 86 MW
Annual output: 504,700 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 27 MVA.
The electricity generated is raised from 10.5 kV to 110 kV by means of four high-voltage main transformers and fed into the grid via the open-air switchgear to 110 kV lines on the Austrian side and two on the Bavarian side.
Five weir fields with a clear width of 23 metres each are equipped with double hook gates with a closing height of 14.2 metres each. The gates are operated by weir chains powered by electric motors and mechanical gearboxes with oil-bath lubrication.

A fish bypass at the Passau-Ingling run-of-river power plant is currently being planned.
As part of the EU project LIFE Blue Belt Danube Inn, the power plant will be equipped with a technical fish pass.
Wherever ecologically valuable and technically feasible, VERBUND has set itself the goal of guaranteeing consistency for domestic fish and aquatic life at the locations of its hydropower plants.
