Further progress in grid expansion: Bundesnetzagentur approves SuedLink section in Bavaria
Year of issue 2025
Date of issue 2025.04.30
The Bundesnetzagentur has today completed the planning approval procedure for another section of the SuedLink power line. This section runs from the boundary of the Bad Kissingen and Schweinfurt rural districts in Bavaria to the federal state border between Bavaria and Baden-Württemberg near Altertheim. The exact route of the new, underground cable for the around 70 km-long section has now been decided. The Bundesnetzagentur had already approved several applications from TransnetBW for an early start to construction work on this section. The planning approval decision now confirms these measures.
Section from Schweinfurt/Bad Kissingen rural districts to Bavaria/Baden-Württemberg border
The section starts at Oerlenbach at the boundary of the Schweinfurt and Bad Kissingen rural districts. From there, it runs westwards and then south-westwards and then crosses the municipal area of Arnstein and Thüngen in the Main-Spessart rural district. It crosses the A 7 motorway near Wasserlosen. East of Thüngen, the section passes Retzstadt to the east and southeast before crossing the Main river to the north of Thüngersheim. It then runs north and west of Leinach in the rural district of Würzburg. It passes the municipalities of Uettingen and Helmstadt and passes under the motorway A 3. The route then heads south-east to bypass Altertheim until the section ends at the federal state border between Bavaria and Baden-Württemberg.
The Bundesnetzagentur is due to publish its planning approval decision (in German) on 30 May 2025 at www.netzausbau.de/vorhaben3-e1.
Background to SuedLink
Project 3 will link up Brunsbüttel grid connection point (Schleswig-Holstein) with Großgartach grid connection point (Baden-Württemberg). TenneT and TransnetBW, the transmission system operators responsible for the project, plan to lay most of the cables together with the cables for the power line between Wilster and Bergrheinfeld West. The two projects are being implemented in parallel by the operators responsible as the SuedLink project. Project 4 branches off in the Schweinfurt rural district in the direction of Bergrheinfeld. This planning approval procedure only relates to part of Project 3.
