Swissgas AG in its role as Swiss Transmission System Operator on the Transitgas pipeline system informs herewith all market participants in Switzerland about the upcoming maintenance periods in 2026 with technical impacts on swiss (entry & exit) capacities at the cross-border points in Oltingue (FRA), Passo Gries (ITA) and Wallbach (GER).

The specified maximum technical capacity always refers to the entry capacity into Switzerland without maintenance works.

At the beginning of March 2026, Swissgas will supplement this overview with additional information about maintenance work on upstream and downstream transmission grids in Germany (OGE)/Wallbach, France (NaTran)/Oltingue and Italy (SNAM)/Passo Gries. This maintenance work may require adjustments to the transport routes and/or other bottleneck measures to ensure a secure supply of natural gas to Switzerland.
