The demand for gas transport capacities in Baden-Württemberg is rising steadily. For this reason, terranets bw is planning the new "Süddeutsche Erdgasleitung" (SEL) natural gas transmission pipeline.

The SEL will start near Lampertheim and run south of Heilbronn, north of Ludwigsburg to Esslingen over a total length of 250 km. In Lampertheim, Grenzhof, Kirchhausen and Löchgau, important network nodes to the existing tnbw network will be built. In addition, it will supply cities, municipalities, power plants and industries with natural gas in the future.

The line is to be built in several construction phases, according to which the delivery dates are based. This tender includes services for the first two construction phases:

Construction phase 1: Heilbronn to Löchgau (24 km) in 2023/24

Construction phase 2: Löchgau to Esslingen (44 km) in 2024/25

The services of further construction phases are the subject of future tenders. Further information can be found under www.terranets-sel.de.

The pipeline is to be built "H2Ready", i.e. suitable for the transport of up to 100% molecular hydrogen.

The planning approval decision from 2010 continues to exist and must be implemented. Individual plan amendment procedures are still pending and will be taken into account as far as possible in the invitation to tender.

The applicant is free to inform himself about the planning approval decision or the application documents for the planning approval procedure. The relevant excerpts will be made available for quotation preparation. The planning approval decision and essential planning documents (current status) will be made available to the interested bidder for download on request.

The private consent of the property owners and managers is also a condition for the start of the work. The acquisition of rights is still ongoing.

The object of the award is the construction work (civil engineering, pipe construction) for the construction of the valve groups and pigging stations.

Civil engineering and building construction for buildings are not part of the award.
