Jochenstein Run-of-River Plant

VERBUND's power plant at Jochenstein is a run-of-river power plant situated on the Danube and in the municipality of Untergriesbach near Passau in Bavaria. It was constructed from 1952 until 1956 by Donaukraftwerk Jochenstein AG.

Technical Description 

On the basis of an agreement between the governments in Germany and Austria and the free state of Bavaria, the Jochenstein power plant was constructed as the first Danube power plant after the Second World War in Austria between the years of 1952 and 1956 and was subsequently the biggest hydropower plant in Central Europe constructed by the Donaukraftwerk Jochenstein AG. It is to this day the largest hydropower plant in Germany. The power plant dams up the Danube at a height of 8.2 m. The weir system lies on the Austrian side of the river, the lockage is on the German side. The powerhouse is located in between and has five installed Kaplan turbines with vertical shafts. These have a nominal output of 28,900 kW each, with an absorption capacity of 410 m3/s each. With the five three-phase synchronous generators, built in screen construction method, they have a total output of 132,000 kW and generate around 850 GWh of electricity on a yearly average. Furthermore, there is a fish ladder being planned for the vicinity of the Jochenstein power plant.
