Nussdorf (Vienna) Run-of-River Power Plant

VERBUND's power plant at Nussdorf is a run-of river power plant situated on the Danube and near the Danube inlet to the Danube canal on the border between the 19th and 20th Vienna districts.

Technical Description 

In mid-2005, the Nussdorf joint-venture power generating plant went into operation. The small hydropower plant, built into the Schemerl weir at the head of the Danube canal, is equipped with twelve matrix turbines and generates around 28 GWh of electricity yearly at an output of 4.8 MW. 

Fish Bypass for the Power Plant at Nussdorf 

In the fall of 2015, VERBUND and its project partners began construction of a modern fish bypass. The Nussdorf fish ladder has been scaled for specimens up to 1.5 m long on the basis of the catfish, a predominant fish species of the Danube, and will cover an altitude differential of around 3.6 m. It has an overall length of ca. 322 metres and is composed of a string of 37 water basins and an open channel area with a near-natural design. This fish ladder will allow the fish to effortlessly bypass the obstacle of the power plant wall.
