The Eglisau-Glattfelden power plant , also known locally as the Rheinsfelden power plant or the Rheinsfelden-Eglisau power plant , is a run-of-river power plant on the Rhine on the border between Germany and Switzerland .
location
The power plant is about halfway between Eglisau and Hohentengen on the Upper Rhine near Rheinsfelden (municipality of Glattfelden ). The backwater extends roughly to the mouth of the Thur . The power plant uses the gradient between the Thur and Glatt estuaries . Since the Rhine forms the border between Germany and Switzerland at this point, some of the facilities are located on German territory. The power plant building is on the Swiss side.
history
The first studies on the construction of a power plant in this area were carried out between 1900 and 1910. After the Zürcher and Schaffhauser Elektrizitätswerke had received the concession for 80 years in 1913 with the approval of the Grand Duchy of Baden , the preparatory work began. In 1914, Nordostschweizerische Kraftwerke AG took over the concession. The plans for the building were drawn up by the architects Gebrüder Pfister . Construction work began in 1915. Due to the damming, numerous houses along the river had to be cleared. In the Oberriet district of Eglisau , for example, 15 of a total of 17 buildings were demolished. The road bridge near Eglisau also had to be rebuilt. Since the power plant was built directly at the mouth of the Glatt , it was diverted through a tunnel into the underwater of the power plant. This tunnel was put into operation on January 16, 1916. The 114.5 meter long weir has six openings, each 15.5 meters wide. The first 18-meter-long construction section of a 12-meter-wide lock was built on the German bank for the navigation on the Rhine planned at the time. The power station supplied electricity for the first time on April 15, 1920. The maximum gradient was 11 meters and the amount of usable water was 390 m³ / s. According to the length of the banks, the state of Baden received 8% of the energy generated, 92% was due to the two Swiss cantons.
The power plant has been listed in the inventory of objects worthy of protection since 1979. A new license was granted on December 16, 1998 and has been in force since April 1, 2002.
All seven machine groups were replaced as part of a power plant renewal. Kaplan turbines are now used instead of Francis turbines . With a flow rate of 500 m³ / s, the new turbines have a combined output of 43.4 MW and produce an average of 318 GWh of electricity per year. The current license ends on December 31, 2046.
