The Obervogau run-of-river power plant was built between 1974 and 1977. Four Kaplan turbines generate an annual average of around 59 GWh of electricity and can therefore supply about 13,300 households with electricity produced entirely from hydropower.
Turbines and generators: Two Kaplan turbines with a diameter of 4.15 metres have a nominal output of 6,500 kW each. The two three-phase synchronous generators have a rated output of 10,000 kVA at a nominal voltage of 6.3 kV.
Transformers: The 20,000 kVA machine transformer raises the generated energy to 110 kV before it is conducted via a tie-in to the line to the Leibnitz substation of STEWEAG.
Weir system: The three-field weir system consists of welded pressure segment gates with flaps; the segments are hydraulically controlled by two pull cylinders and the flaps by a central push cylinder.
