Ybbs-Persenbeug Run-of-River Power Plant

VERBUND's power plant at Ybbs-Persenbeug is a run-of-river plant situated on the Danube and in the municipality of Ybbs and Persenbeug in Lower Austria.

News: Project "Ybbs2020" 

By 2020, VERBUND will invest approx. 144 million Euro in the modernisation and efficiency increase of Austria's oldest Danube power plant Ybbs-Persenbeug as part of the project "Ybbs 2020". The increased output thus generated corresponds to the annual consumption of 17,000 households.

Technical Description 

The oldest Danube power plant in Austria was planned already in the 1920s and was completed in 1959. The power plant was constructed in the riverbed on the Danube and each have a power plant hall on the southern and northern banks. In both of the power plant sections there are three built-in "standing" Kaplan turbines. Each one of them propels a three-phase generator. Since 1996, a seventh machine unit in a small powerhouse on the southern bank generates electricity. In the middle of the power plant facility there are five weir fields, each 30 m wide. On an annual average, the power plant generates around 1,336 GWh of electricity.
