The Pöls run-of-river power plant was built between 1903 and 1904 and underwent a general refurbishment in 1976/77. Today, horizontal Francis turbines generate approximately 9 GWh of electricity annually.
Turbines and generators: The plant is equipped with horizontal Francis turbines that are directly coupled to three-phase synchronous generators. Turbine 1 is coupled to a 600 kVA generator with a nominal voltage of 3,000 V. Turbines 2 and 3 are directly coupled with two 3,000 V generators with an output of 625 kW.
Transformers: A 1,600 kVA machine transformer in a block arrangement is available for all three machine sets. The plant additionally has a 50 kVA transformer to cover its own requirements, which converts the electrical energy from 35 kV to 400 V.
Weir system: A dam gate can be raised and lowered by means of an oil-hydraulic pull cylinder arranged on one side. Control and monitoring are carried out from the central control room in Pernegg.
