TENP gas pipeline system expansion

TENP III pipeline project gathering pace

• Start of preliminary investigations 
• Presentation of the project to authorities

The TENP pipeline system consists of two parallel transmission pipelines built in the 1970s (TENP I) and the 1990s and 2000s (TENP II). Starting at the German-Dutch border, the pipelines carry natural gas over a distance of about 500 km towards Switzerland and Italy. Following the successful completion of a reversal project, they can now also move natural gas from the Swiss border northwards. There are four compressor stations along the route to maintain the pressure required for gas transportation.

Trans Europa Naturgas Pipeline GmbH & Co. KG is a subsidiary of the two gas transmission system operators Open Grid Europe GmbH and Fluxys TENP GmbH. OGE has been commissioned to provide the general engineering services for the TENP III expansion project.

TENP III is needed because of the temporary transmission capacity restrictions on TENP I. The measures now commencing are part of the 2018 and 2020 Gas NDP and ensure security of supply in the Baden-Württemberg region as well as in Switzerland and Italy.

TENP has decided to build the new TENP III pipeline along the same route as TENP I. Project planning has already started and preliminary nature conservation studies, soil investigations and surveying work are currently underway. The project is also currently being presented to the approval authorities.

The project will affect the approx. 38 km route section from Mittelbrunn to Schwanheim in Rhineland Palatinate, the Schwanheim-to-Elchesheim section in Rhineland-Palatinate and Baden-Wuerttemberg, the approx. 30 km section from Schwarzach to Eckartsweier, the approx. 16 km section from Hügelheim to Tannenkirch and the approx. 16 km section from Tannenkirch to Hüsingen, all of which are located in Baden-Wuerttemberg.
