The VERBUND power plant Ybbs-Persenbeug was Austria’s first power plant on the Danube and is located in the municipality of Ybbs, Persenbeug-Gottsdorf and Hofamt Priel in Lower Austria. At Ybbs-Persenbeug, the oldest run-of-river power plant on the Danube, not only the impellers are active. The many cyclists that use the Danube cycle path have also discovered the Danube and the power station as a popular excursion destination. The power plant nestles in a beautiful natural landscape, and the wonderful impressions in Strudengau and Nibelungengau thrill visitors.

Project "Ybbs2020" 

Since 2014, the interior of the ageing power plant has been partially renovated. Each year, one machine set (turbine and generator) is renewed, with all machine sets on course to be successfully replaced by 2022. This will significantly increase the amount of electricity generated by the power plant. The resulting additional generation corresponds to the annual electricity consumption of 22,000 households. 
VERBUND is investing 144 million euros in the comprehensive increase in efficiency at the Ybbs-Persenbeug site. Part of this is being financed by means of the Green Bond

Environmental protection at VERBUND
The Ybbs-Persenbeug run-of-river power plant does not currently provide continuity for fish, as no suitable technology is yet available for overcoming this large drop in height given the cramped conditions.  As soon as new developments are identified, they will be tested by VERBUND for the Ybbs-Persenbeug site.
Below the power plant is the storage area of the Melk power plant. In the coming years, new gravel banks and islands will be created there as habitats and spawning grounds for fish in the area of the “Ybbs disc”, with support from the EU-LIFE+ programme.

Fish bypass

After the Second World War, Ybbs-Persenbeug was one of the most prestigious projects in Austria’s reconstruction. With an output of 236.5 MW, it is the fourth most powerful power plant on the Danube in Austria.

The south and north powerhouses with machines 1 to 6:

The power plant has a total of six main machine sets with vertically installed Kaplan turbines and a total nominal output of 200,000 kW. Three of them are located in the north and three in the south power plant. 

The two auxiliary sets of machinery in the separation columns each consist of a Kaplan turbine from 1957 and 1958 with an output of 1,765 kW and 2,500 kW respectively and a generator.

The powerhouse of machine 7:

With an impeller diameter of 7.5 metres, the horizontally installed Kaplan bulb turbine is one of the largest Kaplan bulb turbines in Europe. This seventh machine delivers a maximum output of 48,000 kW with a head of 10.9 metres. 

Weir system:

The fields of the weir system are equipped with double hook gates.
