The Österreichische Donaukraftwerke AG or Donaukraft was an Austrian company whose task it was to build and operate hydropower plants on the Danube . As part of the 2nd Nationalization Act , it was founded in 1947 as a special company of Österreichische Elektrizitätswirtschafts-Aktiengesellschaft , which was also the main shareholder with a stake of more than 95%.
The aim was the planning and construction of a continuous chain of power plants between the Bavarian- Austrian and the Austro- Hungarian border. This was to ensure the full use of the Danube's hydropower .
The company was the largest electricity producer in Austria. In 1999 Donaukraft was converted into VERBUND-Austrian Hydro Power AG and merged with several other electricity producers. The majority owner is still the Österreichische Elektrizitätswirtschafts-Aktiengesellschaft ( VERBUND group ).
A total of ten run-of-river power plants were built. Two more power plants were planned. Both were not built due to massive protests by the population: one in the Wachau near Rossatz-Arnsdorf (see Wachau # Modern History ) and the other in Hainburg (see occupation of the Hainburger Au ). At Hainburg, the largest power station in the power station chain was to be built with 351 MW.

The Jochenstein power station is owned by Donaukraftwerk Jochenstein AG and operated by Grenzkraftwerke GmbH . The Nussdorf small power plant is located at the inlet weir of the Danube Canal and is operated by its own operating company (AHP, Wien Energie, EVN).
The power plants on the Danube generate a total of 13,200 GWh annually , which is around 20% of the public electricity generation in Austria. With the exception of the small Nussdorf power station, the Danube power stations in the Austrian network form the historically created “Danube rail”, which, unlike the 380 kV high-voltage ring, is operated with a nominal voltage of 220 kV.
The dam walls of most of the Danube power plants are also used to cross the Danube , at least for pedestrians and cyclists.
