Töging am Inn: VERBUND power plant enters retirement
21.09.2021Töging am Inn
After around 100 years, the 14 machine sets still in operation at the historic Töging power plant are finally being shut down. This decommissioning will be followed in 2022 by the initial operation of the new, more powerful power plant, which is currently being built next to the historic existing structure.
After around 100 years, the 14 machine sets still in operation at the historic Töging power plant are finally being shut down. This decommissioning will be followed in 2022 by the initial operation of the new, more powerful power plant, which is currently being built next to the historic existing structure. Instead of the previous 85 MW of installed power, the new Töging power plant will have a capacity of 118 MW and supply electricity generated from renewable hydropower to around 200,000 households.
Today, electricity generation came to an end at the Inn power plant in Töging, at least temporarily – in Q1 2022, partial operation of the new power plant will be possible. Construction of the diversion power plant by Innwerk, Bayerische Aluminium AG, commenced in 1919. By 1924, the weir at Jettenbach-Aschau, the almost 23 km-long Inn Canal and the power plant in Töging were complete. It was a technical pioneering achievement that reliably supplied clean electricity from renewable hydropower until today.
While the power plant was also used for the generation of direct current until the mid-1990s to facilitate electrolysis in the adjacent aluminium production site, it generated only alternative current after the site was closed down, which was fed into the grid.
The temporary shutdown of generation in Töging is required so that the new power plant can be connected to the Inn Canal. There will be an installed capacity of 118 MW (+33 MW), shared between 3 machine sets with Kaplan turbines. 696 million kilowatt hours of electricity should be generated annually in Töging – enough to cover the annual electricity consumption of around 200,000 households.

The old makes way for the new
“Like so often, the old has to make way for the new,” said Karl Heinz Gruber, Managing Director of VERBUND Innkraftwerke on the occasion of the decommissioning of the old power plant, referring to the new power plant that is being built right alongside the historic site. “With en eye on our roots and our past, we are investing in the future of hydropower. Hydropower was the basis for the economic development of the region and will be our constant companion as we look to the future of renewable energy.”The temporary shutdown of generation in Töging is required so that the new power plant can be connected to the Inn Canal.
