VERBUND's Abwinden-Asten power plant is a run-of-river plant on the Danube, south of Abwinden near Linz in Upper Austria.
VERBUND's most powerful watercraft is deployed for the damming of weir field no. 5 of the Abwinden-Asten Danube power plant: the ‘DOKW2’ floating crane needs all its strength to stack the dam beams in front of the weir field. Only then can the actual inspection work begin.
As part of the LIFE+ Network Danube project, VERBUND constructed a near-natural bypass channel around the Abwinden-Asten power plant. This channel serves as a fish pass as well as a place of retreat and habitat for rare species along the Danube.
