Ottensheim-Wilhering Run-of-River Power Plant

VERBUND's power plant of Ottensheim-Wilhering is a run-of-river plant situated on the Danube and in the municipality of Wilhering in Upper Austria.

Technical Description 

The Ottensheim-Wilhering power plant was constructed between 1970 and 1974 with co-financing from Energie AG Oberösterreich and Salzburg AG and was the first power plant on the Danube in Austria to have Kaplan bulb turbines with built-in horizontal shafts instead of the Kaplan turbines with vertical shafts which there had been until this point. This arrangement of the machine units made it possible to employ a lower construction method and to better integrate the power plant buildings into the surrounding landscape. In the powerhouse located on the right riverbank there are nine machine units each made up of a Kaplan bulb turbine and a built-in DC coupled three-phase generator. New biotopes were created in the backwater area of the power plant. The additional habitats in the form of power plant ponds which are as close to nature as possible and fit in with the local area, contribute considerably to the diversity of species and to the biodiversity.
