The transport capacities of the Transitgas system are shared between the two shareholders Swissgas AG and FluxSwiss sagl. The two shareholders manage the transport capacities of approx. 18 billion normal cubic metres from Wallbach/Germany and approx. 8 billion normal cubic metres from Oltingue/France.

The Transitgas system has been adapted in 2017 to transport volumes from GriesPass/Italy to Switzerland, Germany and France.

In Summer 2025, we successfully completed the “TK-B control system upgrade project” implementation. What initially began in 2023 as a straightforward replacement of the obsolete unit control panel, quickly developed into a broader modernization program, incorporating several key improvements:

• Transition from a pneumatic fuel gas control system to electronically controlled valves.
• Upgrade of bleed valve and VGV actuators from hydraulic to electronic devices.
• Complete rewiring of all instrumentation inside the turbine enclosure.
• Replacement of pressure and temperature switches with modern transmitters.
• Modernization of the fire detection system in the main building housing the unit.
• Installation of additional valves on the process compressor to eliminate valve’s intern leakages.

As part of a maintenance project, defective/conductive insulating joints (IJ) near the Ruswil compressor station, as well as leaking valves within the Ruswil compressor station were replaced. The measure was necessary because both the valves and the insulating joints were defective, and their proper functionality could no longer be ensured.

As part of a maintenance project, the conductive/defective isolating joints (IJ) in the Wallbach and Lostorf areas were replaced. This measure was necessary because the existing insulating joints had become conductive and therefore had to be replaced to ensure operational safety.
