The six old turbines will be removed and replaced with new ones by 2030. At the end of the revitalisation, the power plant will provide additional generation for a further 15,000 households. The investment amounts to around 62 million euros.
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.
