The Vienna-Freudenau power plant is the tenth and most recent power station on the Danube river. It was built between 1992 and 1998 using the wet construction method.
Since its opening in 1998, it has been supplying hydroelectric power. The fishpass was the first of its size and was decisive for the ecological power station construction. The powerhouse in the middle of the stream houses six Kaplan-pipe turbines between the lockage and weir. The impeller diameter of 7.5 meters ranks among the biggest turbines in Europe. Each one boosts a directly paired three-phase alternator. Since 2011, the power plant in Freudenau has served as the central station of all nine Danube power plants, with Jochenstein being the only exception. The output of electric energy from renewable sources amounts to approximately 1100GWh each year.
