Power Plant Passau-Ingling

The Passau-Ingling power station is a run-of-the-river hydroelectric power plant on the lower Inn, operated by Grenzkraftwerke GmbH. The owner of the power plant is Österreichisch-Bayerische Kraftwerke AG. The power plant is located in the municipalities of Passau and Schardenberg. It is the last weir on the Inn before the confluence of the Inn with the Danube.

Initial considerations to harness the hydropower of the Inn for electricity generation date back to 1908. Between 1918 and 1931, there were various plans, including the construction of additional diversion power plants based on the model of the Töging canal power plant and the Inn canal built for it. In 1936, Siemens-Schuckertwerke AG presented a design for the construction of five hydroelectric power plants on the lower Inn, which also included canal power plants. In 1938, Siemens-Schuckertwerke AG then presented a modified framework plan that was significant for further development and which abandoned canal power plants. The locations of the five weirs on the lower Inn, as realized during and after World War II, essentially follow this framework plan from 1938.
