2025 results: A solid business model, with the GAIA 2035 plan continuing and taking shape
In 2025, in a geopolitical and regulatory context that confirms the relevance of its strategy, Teréga continues the implementation of its GAÏA 2035 plan. The Group demonstrates its operational excellence, CSR performance, and financial strength, and sees its major strategic projects materialize. These advances anchor Teréga's trajectory towards its ambition: to become a 100% renewable and low-carbon energy hub by 2050, serving decarbonization and French and European energy sovereignty.
2025 results confirming the solidityof the Teréga model
In 2025, in a context of a downward trend in gas consumption, Teréga's results remain solid and in line with Group projections. Revenue stands at €480M and net income at €108M, while the investments necessary for the security of our infrastructure continue and the share dedicated to their decarbonization increases from 9 to 15%.
With storage filling at full capacity as of November 1, 2025, the marketing of 100% of 2026-2027 capacities subscribed and 46% of 2027-2028 capacities already reserved, Teréga confirms its key role and its ability to fulfill its mission of security of supply in France and Europe.
The Group continues the integration of biomethane with 13 sites now connected to its network, for an installed capacity of 690 GWh/year. The Renewable Gas Index (RGI) in the Teréga zone reaches 5.2% on average in 2025, above national averages and in constant progression. In addition, the first three reverse-flow infrastructures were commissioned in 2025.
GAIA 2035: A strategic roadmap taking shape
In 2025, the Group begins the transition to the industrial scale of its major projects in the hydrogen and CO2 sectors:
H2med/BarMar, an underwater pipeline between Barcelona and Marseille in which Teréga holds 16.7%, is recognized as an Energy Highway by the European Union and sees the renewal of its PCI (Project of Common Interest) label proposed by the European Commission.
In the Greater South-West, HySoW, a 650 km hydrogen backbone designed to link regional industrial hubs to the H2med corridor, sees its PCI (Project of Common Interest) label granted for the first time in April 2026.
The CO2 sector also recorded significant advances on two territorial fronts. In Occitanie, Teréga is developing a project around the Martres-Tolosane cement plant. In Nouvelle-Aquitaine, the Group signed a partnership agreement with the Grand Port Maritime de Bordeaux. In total, 2.5 Mt CO2/year of volumes are secured through partnership agreements, within the framework of the national CCUS strategy.
The development of these major infrastructures serving decarbonization and energy sovereignty will require, in addition to the continuation of technical studies and the obtaining of administrative authorizations, the clarification of regulatory frameworks for hydrogen and CO2.
