The Stäubiloch turbine system was a hydropower plant that supplied the Hotel Reinhard on Melchsee-Frutt in the canton of Obwalden in Switzerland with electrical energy until 1954.
history
The dust hole was the natural flow of the Melchsee into the Grosse Melchaa . The water seeped away in this karst cave and only came to light again in several places below. On June 8, 1904, the government council of the canton of Obwalden granted Albert Reinhard-Bucher a concession to build and operate a hydropower plant with an installed capacity of 40 hp (approx. 30 kW ). Reinhard-Bucher installed the turbine system in 1904. This supplied the Hotel Reinhard with electrical energy until 1954. The height of fall was 13 m, the DC machine had a nominal voltage of 200 V and the system, which was equipped with a Francis turbine , was controlled by hand.
The concession for the plant was granted for 50 years and expired in 1954. Today (as of 2018) only a few remains of the former facility are visible. Instead of the turbine system, the Hugschwendi power plant was built from 1955 onwards, but it is located in the valley floor on the Stöckalp and thus uses a gross gradient of 830 meters.
