Operations on the Franco-Swiss Etrez-La Cure-Gland pipeline proceeded satisfactorily in 2025. Capacity was fully utilized, with 7,830 GWh of gas transported and an hourly peak of approximately 1,988 MW. A collaboration is under discussion with the ENGIE Group on various projects, particularly those related to renewable gas.

The surface exploration permit was granted by the Department of Environment and Safety of the Canton of Vaud. Discussions are underway within the Board of Directors regarding the development of a geothermal project. Two directors were replaced during the 2025 fiscal year.

Unigaz ensured the operation of the natural gas pipelines without any restrictions on transport capacity and, most importantly, without any interruption in deliveries to customers connected to those pipelines. Unigaz’s gas pipelines transported a total of 4,923 GWh in 2025, representing a 45% decrease compared to 2024, while the hourly peak reached 1,204 MW (a 44% increase compared to 2024).

Founded in 1999 by the shareholders Gaznat SA, Gasverbund Mittelland AG, and Ganeos, Gas&Com now operates a fiber-optic network covering all of Switzerland and offers high-quality bandwidth and network services.
Gas&Com AG’s annual report for fiscal year 2024/25 paints a very encouraging picture: despite challenging market conditions, the company had a highly successful year. Several strategic projects had a positive impact on the results. Financial indicators - such as above-average operating profit, strengthened liquidity, and a positive financial result - underscore the strength of the business, supported by a prudent and sustainable investment strategy.
Effective retroactively as of January 1, 2025, Gas&Com AG acquired Trigon AG. The two companies remain operationally independent and have formed a strategic partnership that creates valuable synergies and expands the range of services for commercial customers. Together, they are thus strengthening their position in providing innovative, secure, and scalable network solutions for the future.

Founded in November 2002 by the Swiss gas industry, Gazmobile SA, headquartered in Arlesheim (BL), aims to promote the use of natural gas and biogas as fuels. It provides technical support to motorists and natural gas distributors in the purchase of vehicles and the construction of refueling stations.
In this way, it fosters the development of conditions conducive to the operation of natural gas and biogas vehicles. The Executive Board and the Board of Directors are composed of representatives from regional gas companies and natural gas distributors, who contribute their specialized expertise.

Swissgas focuses on its role as a company of national importance in operating its high-pressure pipeline network and managing gas transmission. It has ceased its activities in the field of natural gas supply. A new strategy was approved in 2025, with phased implementation beginning in 2026.

Founded in July 2016 in partnership with Holdinova, Groupe E, Ganeos, Swissgas, and Gas&Com, Swiss Gas Invest aims to acquire, hold, and dispose of equity interests in all companies operating in the natural gas sector. The consortium holds 7,98% of the share capital of FluxSwiss, which in turn owns 46% of Transitgas and 90% of the transmission capacity on the Transitgas pipeline.

According to Article 3 of the Federal Act of 17 June 2016, on National Economic Supply (LAP; RS 531), the business community and the Confederation are responsible for ensuring the nation’s supply of vital goods and services. The establishment of mandatory reserves, which is part of this supply guarantee, is subject to mandatory stockpiling by any entity that imports vital goods. To this end, the Federal Office for National Economic Supply (OFAE) enters into contracts with each of the companies subject to this mandatory stockpiling requirement. Provisiogas, a nonprofit organization, was founded in 2015 by the gas industry to carry out the tasks entrusted by the federal government regarding the implementation of mandatory replacement stockpiling in an efficient manner that does not distort competition (using extra-light fuel oil instead of natural gas, as sufficient quantities of natural gas are not currently available for storage in Switzerland). Its mission is therefore to manage a guarantee fund for natural gas. Provisiogas subcontracts the coordination of the physical storage of extra-light fuel oil to Carbura. In 2025, a new agreement was concluded with Carbura for the supply, storage, and management of fuel oil for the period from 1 July 2025, to 30 June 2030.
