Substation Obersielach

The Obersielach substation is the regional node for the southern region and manages the high-voltage and extra-high voltage levels operating at 380 kV, 220 kV and 110 kV. The substation acts as a base for the maintenance personnel working on the substations in Obersielach, Feistritz, Rosegg, Villach South, Greuth, St. Andrä, Schwabeck, Lavamünd and Wolfsberg as well as for the southern overhead line team. The 380-kV, 220-kV and 110-kV outdoor and gas-insulated switching stations are located on an 11-hectare site which also houses operational building facilities with emergency power supply equipment. 

The Obersielach substation is situated within the municipal area of Völkermarkt and was constructed between 1960 and 1962. The high-voltage installation was first extended between 1984 and 1986 with the addition of the 380-kV switching station. 

The substation is responsible for distributing electrical power from Austria’s trans-regional transmission grid in line with demand. Thanks to a 220-kV line between Obersielach and Podlog and a 380-kV line between Kainachtal and Marburg, there are direct connections to the international extra-high voltage grid. Obersielach serves, among other things, as a feed-in point for power plants on the Drava River. 

The substation is also the base for an overhead line team whose role is to manage the high-voltage overhead lines in the region, ensure that they are operating properly as well as to carry out maintenance work and remedy any faults.
