South German natural gas pipeline - SEL

In order to guarantee a secure energy supply, also when demand increases, it is necessary to develop terranets bw´s gas transmission system. And this is why terranets bw is planning construction of the approx. 250 km long "South German natural gas pipeline" - SEL from Lampertheim in Hesse via Heidelberg, Heilbronn, Ludwigsburg, Esslingen, Göppingen, Heidenheim to Bissingen in Bavaria.

Construction works for SEL will take place in sections, depending on the specific demand trends in the next 10 years.

Discover more about the project and the current status of each section on the SEL project website.
