The Ferlach-Maria Rain power plant was built between 1971 and 1975 as the third power plant on the Middle Drava (after Feistritz-Ludmannsdorf and Rosegg-St. Jakob) with the financial involvement of KELAG. Two Kaplan turbines generate 315 GWh of electricity annually entirely from hydropower.

 

Turbines and generators: Each of the two vertically installed machine sets consists of a Kaplan turbine with a nominal output of 37,500 kW and a directly coupled three-phase synchronous generator with a nominal output of 50,000 kVA. The total bottleneck capacity is 75,000 kW.

Weir system: The three weir fields are equipped with pressure segment gates with weir flaps.

The energy is conducted via 110 kV open-air switchgear directly into the provincial grid of Kärntner Elektrizitäts AG (KELAG).

The run-of-river/swell power plant is not occupied and is controlled and monitored remotely from the Feistritz-Ludmannsdorf power plant.

The Ferlach-Maria Rain power plant was built between 1971 and 1975 and co-financed by KELAG.
