Commissioned in 1931, the Häusern pumped storage power station is the oldest of the five pumped storage plants within the Schluchseewerk AG network and forms the upper level of the three-stage Schluchsee Group, which also includes Witznau and Waldshut. Häusern's upper basin is the Schluchsee, a reservoir with a volume of 108 million cubic meters. Häusern's lower basin, Schwarza Reservoir, serves as the upper basin for the Witznau power station.
