The power plant on the Interlaken shipping canal is an early small power plant that utilizes the gradient between Lake Brienz and Lake Thun to generate electricity.
When the shipping canal was laid from Lake Thun to Interlaken West station in 1892 , a barrage about 3.5 m high was created between the Aare Canal , which leads from Lake Brienz past the Interlaken Ost station to Interlaken and to Lake Thun, and the new underwater canal , where the light and water works Interlaken built the power plant two years later . When the shipping canal was built, a fish ladder had already been laid out for the fish to pass by the weir .
The electricity generated in the power plant was mainly used for electrical lighting in Interlaken. At the start of operation, only two Jonval turbines from Bell Maschinenfabrik were installed, and a third was added in 1897. Two excitation turbines were installed right from the start. In this configuration, the system had an output of 600 hp.
In 1916 the industrial companies Interlaken emerged from the light and waterworks Interlaken . In 1924, all turbines were replaced by propeller turbines from Ateliers de constructions mécaniques de Vevey (ACMV) and supplemented in 1932 with improved intake manifolds.
The power plant has an installed capacity of 0.82 MW . Since the renovation in 1932, it has been set up for an expansion water volume of 30 m³.
In addition, a charging center on the weir with an output of 300 kW supplies 1.2 million kWh of electricity annually. The plant was put into operation in 1996.
