TENP III comprises a total of three new pipeline sections built in the existing TENP I pipeline corridor as well as one new station. The new pipeline sections, which are needed for technical reasons, will ensure security of supply in Baden-Württemberg as well as in Switzerland and Italy. The affected sections of TENP I are currently not in service, so the gas flows are being diverted.
Apart from a section between Hügelheim and Hüsingen, the two TENP I sections from Schwarzach to Eckartsweier in Baden-Württemberg and from Mittelbrunn to Klingenmünster in Rhineland-Palatinate are also affected by the planned work.
The project also includes a new pig trap station near Au am Rhein. 'Pigs' are devices used for cleaning and especially for inspecting pipelines. They are introduced into the pipeline via pig traps, which are the main component of a pig trap station.
On all three sections of the route, the pipeline will be replaced within the same right of way. The TENP I pipes will be removed first, and the new TENP III pipes will then be installed almost entirely in the existing corridor.
A total of five different planning approval procedures with public participation are now underway for the three pipeline sections and the pig trap station. Geographically, two different approval authorities are responsible for the section from Schwarzach to Eckartsweier. Construction along this section of the route is due to start in early 2023 with completion scheduled for 2024/2025.
For the section from Mittelbrunn to Klingenmünster, the Structural and Approval Directorate of Northern Rhineland-Palatinate issued its planning approval decision on 25 October 2022. Construction work has been underway here since April 2023. Before that there was preparations for construction work, such as the establishment of the working strip and logging work.
