The Wildegg power plant was a run-of-river power plant owned by the Jura-Cement factories on the Aare near Wildegg in the canton of Aargau , which was operated from 1890 to 1945. The water rights of the diversion power station were taken over by the Rupperswil-Auenstein power station and the cement factory's power station was discontinued. Until the end of the concession for the Wildegg power plant, Rupperswil-Auenstein supplied replacement energy to the cement factory .

history

JCF power plant Wildegg, as it was before the construction of the weir around 1895

The Wildegg cement factory with its own power station went into operation in 1890 after a two-year construction period. The water was collected in the Rupperswiler Schachen ^▼ and passed through a works channel to the power plant's machine house ^▼ , which was located between the cement factory building complexes on both sides of the channel. The underwater channel led ^▼ about 80 m above the Aarebrücke in Wildegg in the river.

In 1893 the factory was expanded for the first time. In order to supply the power plant with more water, a weir ^{▼ was} built in the Aare in 1895 . In 1911 the overflow located in the machine house was removed and replaced by a channel above the machine house. The vacated space was used to install another turbine, which went into operation in 1913. The overflow channel was closed by a weight-loaded flap weir ^▼ , which was automatically opened by the rising water level.

In 1928 seven turbines were in operation - four Francis turbines and three older Jonval turbines , two of which were replaced by Francis turbines in the same year. The power plant was able to deliver an output of 2400 hp, the majority of which was transmitted to the work machines with the help of a transmission line and cable gears . Only an 80 HP Francis turbine was used to drive a direct current generator for the factory lighting. The turbines came from Rieter in Winterthur and the Bell machine factory in Kriens near Lucerne .
