TENP III is live: boosting energy security and paving the way for hydrogen

The TENP III pipeline was officially inaugurated with a celebratory event. This 110-kilometre pipeline replaces one string of the TENP that stretches from the German-Belgian and German-Dutch borders all the way to Switzerland. Following the successful completion of about three years of construction work, the modernised transport system is now up and running – playing a key role in making Europe’s energy supply more secure and sustainable.

A joint effort by German TSOs Open Grid Europe (OGE) and Fluxys TENP, TENP III makes a significant contribution to security of supply in Baden-Württemberg, Germany and Europe. The project also strengthens the link between northwestern Europe and the Italian gas market and – thanks to its bidirectional flow – increases capacity to Switzerland. On top of that, the newly laid pipes are already fully H2-ready. Together with partners, OGE and Fluxys are exploring how hydrogen could flow from Italy through Switzerland and, via TENP, to Germany. This additional import route could increase the diversification of European hydrogen supplies.

Friedrich Rosenstock, Managing Director of Fluxys TENP, emphasizes: “With TENP III, we are connecting countries and regions – and the energy world of today and tomorrow. The project is not only proof of our commitment to security of supply, but also future-proof.”

Detlef Brüggemeyer, CTO of Open Grid Europe, adds: “TENP III is a strong signal for a reliable energy supply in Europe. It shows that we can implement infrastructure projects efficiently and with a view to the future.”

The pipeline was replaced in three sections across Rhineland-Palatinate and Baden-Württemberg, starting in 2022. Construction work was successfully completed in summer 2025. Almost 93 percent of the technically necessary replacement was carried out within the existing route. In the coming weeks, final work will run in parallel with ongoing operations but will not affect the transport function.
