General renewal of the Jauntal line
With the general renewal of the Jauntal line in Carinthia, APG is ensuring a secure and sustainable electricity supply in the region and thus enabling the transformation to a more ecological energy system.
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.

Positive decision for the general renewal of the Jauntal pipeline
The general renewal of the Jauntal line between the APG substations Schwabeck and Obersielach (Carinthia/Jauntal) has been approved by the Carinthian provincial government in accordance with the Carinthian Electricity Act (K-EG). APG is investing around EUR 70 million in the general renewal of the 110-kilovolt line through the Carinthian Jauntal (districts of Völkermarkt and Wolfsberg). This will increase the line capacity by around 300%. The increase in capacity lays the foundation for ensuring a secure supply of electricity and a sustainable energy future for a strong region in the long term. The general renewal of the 19 km-long line will be implemented from 2026 to 2028.
Carinthian provincial government issues permit under heavy current law
After the submission documents were reviewed by the authority, an oral hearing was held on 27 February 2025. The hearing in accordance with the Carinthian Electricity Act took place in Ruden (district of Völkermarkt). By decision dated March 14, 2025, the Carinthian provincial government granted approval for the general renewal of the power line. This decision has now become legally binding following the expiry of the appeal period. The other material approval procedures have been completed by the relevant authorities and are also positive - with the exception of the outstanding approvals in the areas of forestry and aviation.
The renewal of the Jauntal line is part of APG's investment program until 2034 (Grid Development Plan 2023) in the amount of 9 billion for the success of the energy transition in Austria and a key project for the region To the press release
Information event on the start of construction of the general renewal of the Jauntal pipeline
The existing 110 kV line was partly built in the 1940s. Due to its long service life, it is no longer able to meet the energy industry's requirements for the future of electricity (consumer growth, electrification of the economy, industry & society). In order to continue to guarantee a secure power supply in the region, the line must be adapted to the state of the art. For this reason, we cordially invite you to visit us at our info talk day and talk to us personally about the project:
Date: 4 September 2025, 16:00 - 19:00
Location: Bildungszentrum Ruden / Veranstaltungssaal Obermitterdorf 50, 9113 Ruden
APG in conversation: Information talk day in Ruden
On April 25, APG and the municipality of Ruden invited landowners and residents to a project information event in the municipality's cultural hall to discuss details of the general renewal project for the 110kV line from Obersielach to Schwabeck (Jauntal line). Just over 40 interested citizens took up the offer and spent several hours talking to APG employees and the municipality.
Austrian Power Grid (APG) renews 110kV line in Jauntal/Carinthia
Existing line is over 70 years old in parts and no longer meets current energy industry requirements
The existing 110kV line from the Obersielach substation (Völkermarkt district) to the Schwabeck substation (Wolfsberg district) was built in the 1940s and 1960s and is now in need of renovation due to its long service life. The existing line, which is around 20 km long, is therefore to be completely renewed while retaining its length in order to ensure a reliable supply of electricity in the region for generations to come.

Positive effects
- General renewal: The line, some of which is over 70 years old, no longer corresponds to the state of the art; the general renewal is intended to make the line fit for the future.
- Secure power supply: The renewal of the line will ensure security of supply in view of the increasing share of renewable energies in Carinthia (the current line is not designed to transport such quantities of clean green electricity).
- Achievement of climate and energy targets: The renewal will enable the further electrification of the economy, tourism and society. The project therefore also makes an important contribution to achieving Austria's climate and energy targets.
- Investments: The investments in this line create high regional and supra-regional added value and strengthen Carinthia as a business location.
