The Rhine power plant Albbruck-Dogern is a run-of-river power plant on the Upper Rhine . It was built between August 1930 and September 1933.
history
The application for a concession for a hydropower plant with a barrage near Dogern was submitted by Gruner from Basel together with the Escher Wyss & Cie. submitted in Zurich. The Swiss license was granted on June 11, 1926, the Baden license on June 14, 1926. The two licenses were assigned on November 29 to the Rheinkraftwerk Albbruck-Dogern AG ( RADAG ) founded on September 16 . The first concession allowed only 750 m³ / s to be used, which was too little for the planned power plant. Therefore, an application was made for an increase to 900 m³ / s during the construction period, which was received on December 1, 1933. After measurements, the maximum permissible amount of water was set at 1060 m³ / s. This increase was decided by the Swiss Federal Council on December 22, 1944. The concession was renewed in September 2003 and also includes the construction of a new weir power station next to the weir on the Swiss side. As a result, both the overall performance of the barrage and the amount of residual water in the course of the Rhine can be increased.
The construction costs for the construction of the plant in the 1930s amounted to 54 million Reichsmarks or 67 million Swiss francs.
The construction management for structural and civil engineering work was the responsibility of Heinrich Eduard Gruner's engineering office , while the construction management for the electrical part was under the responsibility of Rheinisch-Westfälisches Elektrizitätswerk AG . The machine house is on the territory of the German municipality of Albbruck , the weir on the territory of the German municipality of Dogern and the Swiss municipality of Leibstadt . On the Swiss side, there is the weir power plant, which went into operation on December 4, 2009. A footpath leads over the weir.
The RADAG retrofit project has been running since September 2015 to optimize the machine sets with a cost of 43 million euros. The project should be completed by mid-2019 and increase the output of the plant by 10%.

The weir is located around 700 meters above the Leibstadt train station, where the Rhine used to split up and flow around a floodplain. The five-guard weir closes the entire southern main inlet, with the three southern openings on Swiss territory and the two northern openings on German territory. The northern branch was redesigned to become the headwater canal of the power plant. The Auhof island in between became a reservoir.
The water flows in via a 215 meter long inlet structure, which consists of a sill that protrudes about 5 meters above the river bed and a diving wall that protrudes 1.5 meters into the water. This prevents sediment and floating debris from entering the upstream channel. The 255 meter long inlet basin has a bottom outlet. The upper water canal is 2.935 kilometers long and leads to the machine house near Albbruck, which is connected by a 200 meter long underwater canal. The dam is around 12 kilometers long and extends up to around 400 meters above the Waldshut-Koblenz railway bridge . The large lock planned for this barrage was never built. A dock ramp was built for small boats. Between 2007 and 2008 a weir power plant was built next to the weir on the Swiss side, which was put into operation on December 4, 2009.
The machine hall houses three Kaplan turbines, each with a capacity of 350 m³ / s. The weir power plant has a bulb turbine with an absorption capacity of 300 m³ / s.
The first three generators each had a maximum output of 25,000 kilowatts (kW) at the terminal, so a total of 75,000 kW. Thanks to modernizations that have been carried out, the output per turbine group on the generator is now 28,000 kW, or 84 MW. In addition, there is the weir power plant with 24,000 kW. In 2010, the barrage had a total machine output of 108 megawatts. The original plant from 1933 assumed an average annual output of 530 million kilowatt hours per year. For 2010, the operator specifies the amount of electricity that can be produced annually as 650 million kilowatt hours per year.
On the German side, the power plant feeds into the electricity grid of the transmission system operator Amprion at the 110 kV high voltage level . The power plant also feeds into the Swiss electricity grid.
