Ruppoldingen run-of-river power plant

Equipped with two propeller turbines, the power station has a capacity of 23 MW and generates some 115 GWh per year. The 5.9 metre Kaplan turbines are among the largest waterwheels in Switzerland. The construction of the new building in 2000 included various environmental protection measures as well as measures to restore and rehabilitate the natural landscape along the River Aare. Water expanses, islands and natural growth areas were established along an 8.4 kilometre stretch of river. Instead of the old canal, a 1,200 metre fast-flowing watercourse was built for aquatic life forms. The ecological development is continuously documented and assessed by experts during periodical environmental audits. At the beginning of 2010, the Association for Environmentally Sound Energy (VUE) awarded the Ruppoldingen power station the naturemade star certificate.
