Our history
Gaznat has accompanied the development of the Swiss gas industry for over 50 years.
Gaznat was founded as an engineering company with the mission of promoting the arrival of natural gas in French-speaking Switzerland.
This marks the beginning of the construction of a structured supply network for the region.
Commissioning of the first Suisse Romand (GSR) gas pipeline.
This route links Bex to Vernier, passing under Lake Geneva via a sublake installation never before seen in Europe. This technical feat establishes a strategic energy link between Valais and Geneva.
Creation of Unigaz SA to connect the Swiss network to Transitgas.
Construction of a second underwater pipeline between Les Grangettes and Gland.
This strategic route increases transport capacity, with technical landings at Clarens, Lausanne-Bellerive and Tolochenaz, while preserving the Lake Geneva landscape.
Commissioning of the Trélex-Colovrex gas pipeline on May 9, 2014.
This new section will enhance Geneva's security of supply and adapt the network to the continuing growth in demand for natural gas in the region.
Inauguration of the Innovation Lab in Aigle, a semi-industrial test facility dedicated to renewable energies.
The GreenGas project, developed in collaboration with EPFL, enables Gaznat's control and monitoring center to become energy self-sufficient thanks to Power-to-Gas, and to recycle CO2 as a by-product.
