General renewal of the Jauntal line

The components of the existing 110 kV line from the Obersielach substation (Völkermarkt district) to the Schwabeck substation (Wolfsberg district) were built and installed in the 1940s and 1960s and are now in need of renovation due to their long service life. Therefore, the existing line, which is around 20 km long, will be completely overhauled along the same route to ensure a reliable electricity supply in the region for generations to come.

The Jauntal line will be completely renewed for 50 million euros 

During the general overhaul, the voltage level of 110 kilovolts will be retained and pylon locations will remain identical. In addition to the important modernization of all components (including pylons, foundations, fittings) the existing single cable will be replaced by a two-rope bundle. This will increase the transmission capacity and improve reliability. The line can currently transport 640 amperes (A) per line system. The modernization according to state-of-the-art standards will increase the line capacity to 2,500 amperes per system. This means that with the capacities available in the future, it will be possible to integrate corresponding quantities of renewable energy from the region. 

Following the Carinthian Electricity Act (K-EG), the project will be submitted to the competent authority, the Carinthian provincial government, in the summer of 2024. Various specific issues governed by administrative law (e.g. nature conservation, forestry) will be examined concomitantly in individual procedures by the responsible authorities. This should facilitate a quick implementation of the project. The planned investment volume on the part of APG is around EUR 50 million. The construction work is supposed to begin in 2026, and the renewed line’s start of operation is scheduled for 2028, as the project is fundamentally important for a secure energy supply in the Carinthian Jauntal Valley.
