New concession for the Egglfing-Obernberg power plant planned by 2020


The ecological upgrade of stream landscapes with a green infrastructure is creating healthier ecosystems with greater species diversity and new habitats for these species. These four stream landscapes are the Große Kößlbach, the confluence of the Saagbach with the Danube, the Simbach and the polder area of the Weitbach and the Westerndorfer Graben. This project is funded by the European Region under the INTERREG V-A Programme Austria–Bavaria 2014–2020.

The Egglfing-Obernberg, Ering-Frauenstein and Braunau-Simbach power plants were built during the Second World War. This is still evident today, which is why there are precautions for mine defence. Despite the difficult conditions during the construction of these power plants, they are currently important suppliers of the Bavaria and Upper Austria region with electricity generated entirely from hydropower.

Ecology & environmental protection

A modernisation of the power plant as well as the construction of a fish bypass is planned in the coming years (scheduled for completion by 2020). 
The 12.7 kilometre-long storage area is part of the Unterer Inn conservation area. It will be given an approx. 10.5 kilometre-long dam on the Bavarian side, while a 7.5 kilometre-long dam will extend from Graben to the confluence with the Achen on the Austrian side. The area of the Mühlheimer Niederung behind the Mühlheimer Damm on the right bank will be drained by the Mühlheim pumping station, while on the left bank the waters will be discharged into the tailwater through existing old courses.
Responsible treatment of the environment
The Egglfing-Obernberg power plant was built between 1941 and 1951. During construction, the power plant fell partly into Allied hands and was not completed until after the end of the war.

Powerhouse: The low-profile powerhouse without machine hall accommodates six Kaplan turbines with an average annual production of around 485 GWh.

Weir: The five weir fields each have a clear width of 23.5 metres and are 13.5 metres high. The weir was renovated in 2000.
