Situated at an altitude of 495 meters, the power station utilises a gross head (vertical drop) of 1643 meters, which represented a world record until 1934. The water is drawn from a reservoir at 2135 meters above sea level. The power plant boasts an unusual feature: a theatre in the former machine house, where performances are regularly held.

The plant has been out of service since January 2013 due to a technical defect. Forces Motrices de Fully SA is analysing various options for the future of the hydroelectric power station.
