After more than 80 years of continuous operation the time had come for a general overhaul at the Rheinkraftwerk Albbruck-Dogern AG (RADAG) hydroelectric power station on the Rhine. All three turbines and the control system are being replaced. According to current planning approximately €43 million will be invested in this maintenance project.
First turbine back on stream
The overhaul project at the Rheinkraftwerk Albbruck-Dogern AG (RADAG) hydroelectric power station has reached an important milestone: the first of three new turbines has been installed. The hydroelectric power station, in which innogy holds a 78% share, produces enough electricity to supply an equivalent of approximately 180,000 households with climate-friendly energy.

|Impeller||4 blades; 6.10 m diameter|
|Nominal flow rate||300 cubic metres per second|
|Construction costs||approximately €70 million|
Technical details of the Rhine hydroelectric power station (old plant)
|Annual generation||580 million kilowatt hours (standalone operation)|
|Average output||77 megawatts|
|Turbine||3 x Kaplan turbines|
|Impeller||Diameter 7 m|
|Nominal flow rate||1,100 cubic metres per second|
The power station
On the Upper Rhine the Rheinkraftwerk Albbruck-Dogern AG (RADAG), in which RWE Innogy holds a majority share, has realised one of the biggest hydropower projects in Germany. Since 1933 the Rhine hydroelectric power plant reliably produces green electricity. The dam hydroelectric power station has been in operation since December 2009 and has increased the total average annual output to 650 million kilowatt hours of electricity.
The ecological situation of the river has also greatly improved. Newly created shallow water zones invite fish for spawning, and diversion channels even enable salmon to safely migrate upstream. Over four million euros were invested in the ecological revitalisation measures.
Modernisation measures from 2013 to 2019
As part of an extensive modernisation project the existing power station will be equipped with state-of-the-art technology. It is expected that the three turbines with a capacity of 30 megawatts each will be replaced by 2019.
