Project to renovate the Jettenbach-Töging am Inn power plant

VERBUND renovates the Jettenbach-Töging hydropower plant. The plant is to supply around 200,000 households with clean, domestic electricity in the future.

Architecture and ecology

The project currently being applied for provides for an increase in the dam’s final level and a new powerhouse next to the existing power plant. The impressive, heritage-listed structure of the old power plant will remain and the new building will be integrated into the existing architecture. The capacity of the current power plant will be increased by almost 20% as a result of the new construction and will thus supply even more valuable green electricity for the region. The environment will not be neglected either: extensive accompanying ecological measures are intended to protect existing habitats and improve the living conditions they offer.

The shell of the power plant

The design of the façade by Format Elf architects from Töging was also presented, how the new power plant building is functionally integrated into the surrounding terrain and how it enhances the view of the heritage-listed powerhouse, which dates to the 1920s. According to the architects of Format Elf, the new power plant generates more electricity without being visible.

Project milestone: Early measures allowed

The Töging-Jettenbach Renewal Project has been submitted to Mühldorf District Office for approval. The approval procedure is still ongoing. However, the authority has established that the proceedings have not revealed any aspects that would prevent the positive completion of the application. This was established by notice, thereby creating the possibility to bring selected measures forwards.

Project consultations in May

Project manager Bernhard Gerauer and his team are regularly in Töging or Jettenbach to answer any questions and for a personal discussion about the Töging-Jettenbach power plant renovation project. A project consultation will be held in the project office in Töging (Werkstrasse 2, Töging am Inn) on Tuesday, 7 May 2019 from 5.00 pm to 7.00 pm.

The canal power plant

The Jettenbach-Töging power plant consists of a weir and the approx. 20 km-long Inn Canal, which leads to the Töging power plant. The weir of the Jettenbach-Töging power plant was built by Innwerk AG between 1919 and 1924. It was the first weir structure on the Inn in Bavaria. At the 6-field, 122 m-wide weir, the river’s flow is discharged over the inlet structure into the Inn Canal and on to the canal power plant at Töging. The term Jettenbach weir has entered popular parlance here, although it is actually located in the municipality of Aschau.

The ground-breaking ceremony for the oldest power plant on the Inn at Töging took place in 1919. Construction was carried out by “Innwerk, Bayerische Aluminium-Aktiengesellschaft” founded in 1917. The plant is designed as a canal power plant because the construction of the canal enabled a head of around 30 metres at the location in Töging, which was required for the most effective use of the Francis turbine available at the time.

The project currently being applied for envisages the construction of a new weir in Jettenbach with an increase of 70 cm in the final level, the corresponding adaptation of dams and dikes in the reservoir area, an increase of up to 70 m³/s in the volume of expansion water and the installation of three Kaplan turbines. The latter will be housed in a new power plant building whose external façade has been designed by the architects Format Elf from Töging. 

Due to the special conditions at the Töging site, the annual output will be increased by 120 GWh to a total of 685 GWh through the use of state-of-the-art machine technology. This will result in a unique increase in efficiency of over 18%. The total output of the renovated power plant on the Inn will correspond to the annual electricity consumption of around 200,000 Bavarian households.

Extensive supporting ecological measures will improve the overall ecology of this section of the river:

  • Creation of still waters as spawning grounds and fish habitats
  • Establishment of downstream continuity for fish on the Jettenbach
  • Meadow development at the embankments to promote biodiversity
  • Creation of reptile habitats
  • Structural and hydromorphological improvements
