Ybbs2020: more electricity from the Danube

VERBUND is currently modernising Austria's oldest power plant in Ybbs-Persenbeug on the Danube.

The € 144 million investment in Project Ybbs2020 will increase production by more than 77 million kilowatt hours (kWh) and increase reliability once more as well. The six old Kaplan turbines will be replaced, the control system technology improved. The 6 % increase in efficiency equals the yearly electricity usage of 22,000 households.

These measures at the existing power plant Ybbs-Persenbeug make it possible to significantly increase the production of electricity through hydropower and thereby to cut back CO2 emissions by another 62,000 tonnes per year – without any structural intervention in the surroundings.

Ybbs-Persenbeug ranked among the most prestigious reconstruction projects in Austria after World War II. With an output of 236 MW, it is the fourth most powerful Austrian power plant on the Danube, and with its annual production of 1.336 billion kWh, it saves 1.1 million tonnes of CO2 per year. Nowadays the power plant is a popular destination for an outing on the Danube cycling track.

Renaturation below the power plant

Below the power plant, the reservoir area connects to the downstream power station. There, in the area of the "Ybbser Scheibe" plane, new gravel banks and islands will be created to provide habitats and spawning grounds for fish in coming years.
