The mini-hydro IPP rated at 2*90 kW is operated in "Pfullingen an der Echaz"

In rare cases excessive rainfalls or snow melting is exceeding the rated capacity Level control is then disabled running the units at their maximum - "fully open"

The old 135 kVA synchronous generator was originally operated with a noncontinuously acting rheostatic excitation system (left photo, center panel)

Located in an old cotton factory the mechanical speed controller was taken out of service and replaced by an electro-hydraulic governor

Originally, the rated voltage was 525 V feeding to the 10 kV grid via 800 kVA step-up transformer

The marble panels are in good shape and still fully equipped with old meters
