In this agricultural region of the Mostviertel and Mühlviertel, the power plant is not only an important supplier of electricity generated entirely from hydropower, but also offers cars, pedestrians and cyclists an important crossing over the Danube.
The power plant impresses with its output of 210 MW. This capacity is currently being further improved by VERBUND through investments in increasing efficiency. The goal of the complete overall is not only to extend the service life, but also to renew the turbine, generator (rotor, stator) incl. switchgear, transformer and the cooling system of the machine set. Thanks to the latest state of technology, the machine set will also run more efficiently. Until 2024, one generator will be replaced every year, which is expected to increase generation by 12 million kilowatt hours through increased efficiency.
An open-field solar installation supplements generation on the power plant site. The installed capacity is 17 megawatts. To support the grid frequency, the “Blue Battery” has up to 10 megawatts of spare capacity available – fed from the electricity of the Danube power plant Wallsee-Mitterkirchen.
Additionally, a new PV facility on the site of the Danube power plant Wallsee-Mitterkirchen, which covers an area of 3 hectares and has a maximum output of 1.7 MW, generates as much as electricity as is consumed by about 600 households every year. The panels align themselves automatically to the sun to supply the optimal electricity yield.

Powerhouse:
The powerhouse has six main sets of machinery dating to 1968, each consisting of a Kaplan turbine with vertical shaft and a three-phase synchronous generator with a shielded design. The generators have a nominal power of 42,500 and 44,000 kVA, respectively.
Weir system: The fields of the weir system are equipped with double hook gates.
Locks:
The lock gates at the upstream end were designed as a guillotine gate with double hook contactor, the lock gates at the downstream end as bolt gates with a back wall made of sheet metal.
