Pernegg Run-of-River Power Plant

Technische Beschreibung 

The Pernegg power plant was built from 1925 to 1927 and is a combination of a run-of-river and a diversion power plant on the river Mur. The three weir fields have been equipped with double hook protection gates. The works water flows into the roughly 2.3 km long diversion canal to the Pernegg power house. In the power house three machine units with vertical shafts and a bottle neck capacity of altogether 21,900 kW were installed. Each machine unit comprises a Kaplan turbine and a three-phase synchronous motor. To be able to use the residual water run-off, weir facilities and a Kaplan bevel gear turbine were built alongside it. In total, every year around 119 GWh of electricity are generated. Furthermore, Pernegg power plant has a fish ladder.
