The Töging power plant is a diversion power plant of the Austrian Verbund AG . The power plant is located on the Inn Canal near Töging am Inn .

investment

At the dam Jettenbach most of the water of the Inn is in the Innkanal diverted to utilize the local altitude. The canal leads the water with a height difference of only 6 meters over 20 km to the water tower of the Töging power plant. There, the water flows through pipes 30 meters deeper into the power plant and drives the turbines in the process. 2.8 km after the power plant, the underwater of the Inn Canal flows back into the river.

The following parts of the facility are under monument protection (as of July 17, 2015):

Canal power plant (diversion power plant), hydropower plant of the former Innwerk, Bayerische Aluminum AG, architectural design probably based on plans by Hermann Buchert, 1919–1924;

  • Power house, elongated hipped roof building with plastered plaster and window surfaces, rusticated corner frames and a low rear extension, with eight tower-like structures with tent roof, with technical equipment
  • three cable bridges in the former furnace halls, concrete structures with saddle roof and lunette windows on concrete pillars
  • Moated castle, elongated saddle roof structure with plaster structure and rusticated corner edging, flanking towers with hipped roof, with technical equipment
  • 15 riveted pipe tracks with concreted abutments between the water tower and the power station
  • Energy destroyer with discharge drain
  • Compressor house, single-storey saddle roof building with plaster structure
  • Experimental station, single-storey saddle roof construction

history

The hydropower plant was built from 1919 to 1924 by the Innwerk, Bayerische Aluminum AG company to supply an aluminum smelter planned directly next to the power plant with electricity. A total of 15 Francis turbines , each with a generator, were installed in the power plant . On January 1, 1925, the United Aluminum Works took over the aluminum smelter, while the power plant remained part of the Innwerk.

Up until the end of aluminum production, 7 of the generators were direct current generators connected directly to one of the smelter's furnace houses. The other 8 generators supplied three-phase current , which was then rectified . After aluminum production was stopped in 1996, 6 of the DC machines were converted to three-phase current. One of the machines was shut down. Since then, only 14 turbines have been used and the electricity is fed into the high-voltage network.

Innwerke's successor, E.ON Wasserkraft  GmbH , sold the power plant to the Austrian Verbund AG in 2009 due to antitrust law .

Planned new building

The operator is planning to extensively renew the system. For this purpose, the water level of the Inn Canal is to be increased and the previous power plant is to be replaced by a new building. There, 3 Kaplan turbines should generate around 20-25% more electricity than before. The listed previous power plant would be taken out of service, but should be retained.

The plan is to increase the output to 118 MW, with which around 700 GWh of electrical energy can be produced per year, which corresponds to the annual electricity requirement of 200,000 households. In addition to this modernization and increase in efficiency, a large number of ecological protective measures are also intended to minimize the environmental impact of the power plant. Overall, the renovation, the preliminary work of which began in 2018, is expected to cost around EUR 250 million.
