Large run-of-river Plants
The Flumenthal power station was first put into service in 1970. Following measures to increase the efficiency to 23.7 MW, the average annual output of the three turbine-generator groups is 146 million kWh of renewable hydroelectric power. This corresponds to an increase in electricity production of six percent.
Built in 1917, the Gösgen power station has an annual output of around 300 million kWh and is one of the largest run-of-river power plants on the river Aare. Between 1997 and 2000 the power station was completely rebuilt and now produces twelve percent more electricity with the same flow of water. In 2004 a new fish ladder was put into operation ...
Situated at the junction of the Rivers Aare and Rhine, the power station with its 3 Kaplan turbines is the furthest downstream generation site on the River Aare. Its construction created jobs during the slump of the 1930s. The reservoir and environs are now part of a nature reserve of national importance.
Equipped with two propellor turbines, the power station has a capacity of 21,1 MW and generates some 115 million kWh per year. The 5.9 meter Kaplan turbines are among the largest waterwheels in Switzerland.
The low-pressure run-of-river power station is located on the River Rhine below Stein-Säckingen. The four Kaplan turbines, each with a capacity of 27.5 MW, represented a pioneering achievement when first commissioned back in 1931. Switzerland's share of this border power station is 50 percent.
