The Rhine power plant Iffezheim is part of the Iffezheim barrage and is the largest run-of-river power plant in Germany and one of the largest run-of-river power plants in Europe. It is the tenth and last power plant in the Upper Rhine chain north of Basel . The operator is Rheinkraftwerk Iffezheim GmbH (RKI). The company is owned half by EnBW Kraftwerke AG and one half by Électricité de France (EDF).

history

The facility was built in the mid-1970s on the basis of a Franco-German state treaty from 1969 about four years after the completion of the neighboring Rheinau-Gambsheim barrage directly in the course of the Rhine. It was put into operation in 1978.

With an investment volume of around EUR 100 million, construction work began in the summer of 2009 to expand the power plant with an additional machine set. It went into operation in June 2013 and generates a further 122 million kWh annually. As part of the expansion work, a fish ladder for salmon was also built.

The power plant is equipped with four identical sets of machines. The running wheels of the horizontally lying bulb turbine have a diameter of 5.80 m and run at a speed of 100 rpm. They act directly on the 60-pole salient pole machines , which each develop an output of 27 MW .

The fifth machine set with an output of 38 MW was built by the Austrian company Andritz AG . The bulb turbine has an impeller diameter of 6.80 m, the nominal speed is 83.33 / min. Since the expansion, the Iffezheim power plant has been the most powerful power plant on the Rhine with an installed capacity of 146 MW. The planned average annual energy production then increased by around 17% to around 860 GWh. This corresponds to an average output of approx. 98 MW (approx. 1/43 of the Neurath power plant ). The fifth machine set went into operation in June 2013.
