The Wettingen reservoir is a reservoir on the Limmat in the Swiss canton of Aargau and is used to operate the Wettingen power plant . The lake is located in the Limmat Valley between the villages of Würenlos and Wettingen on the right bank of the river and Killwangen and Neuenhof AG on the left bank.
history
The reservoir was completed in 1933. The power plant is located above the wooden bridge at Wettingen Abbey and 50 meters above the railway bridge. It is operated by the Zurich City Electricity Company (EWZ). The first concession for the power plant ran until 2013. Since major renovation work was necessary around the turn of the millennium, but the investment costs of 60 to 70 million francs were not justifiable given the short remaining term of the concession, the EWZ applied for an extension of the concession in 1998. Linked to environmental requirements, this concession was granted for 80 years by the Grand Council of the Canton of Aargau on January 16, 2001. Part of the bank barriers below the power plant had to be dismantled and the 600 meter long fish ladder fish pass at Wettingen power plant was built to bridge the dam .
technology
The weir and the machine house are built next to each other across the river on solid Molasse rock . The weir has four weir openings. The power plant has three turbine-generator groups. In order to increase the gradient, the water flows below the turbines through an underwater tunnel under the Limmat bend and flows into the river further down.
The installed capacity of the power plant is 26.1 MW ; each of the three main machines has a maximum output of 8 MW and the smaller doping machine an additional 2.1 MW. The annual production is 135 million kWh .
Industrial culture
Due to its technical and historical significance, the Wettingen power plant is a stop on the Limmat-Wasserschloss industrial culture trail .
