Terega

What Terega does

Teréga is a French regulated gas transport and storage operator headquartered in Pau, France, with operations dating to the 1940s. The company operates 5,106 km of gas pipelines representing 13.5% of the French gas network, transporting 117.2 TWh of gas annually, and maintains 6.4 Gm³ of underground storage capacity with 34,000 GWh subscribed at 100% availability. It serves 84 shipper clients for transport, 37 shipper clients for storage, 8 public gas distributors, and a growing base of industrial customers, biomethane producers, and NGV station owners across Southwest France.

The company's revenue model is anchored in regulated tariffs set by France's Energy Regulation Commission (CRE), with three primary streams: usage-based gas transport capacity subscriptions, subscription-based storage services with multi-year contracts, and one-time connection fees for industrial customers, distributors, biomethane producers, and NGV stations. In FY2025, Teréga reported €480M in revenue and €108M in net income. Distribution is conducted through dedicated enterprise field sales teams (named account managers for shippers, industrial customers, distributors, biomethane producers, and NGV stations), supplemented by a customer portal with private API access. The company holds 100% customer satisfaction among industrial customers and shippers in 2025 surveys.

Teréga's strategic positioning centers on its GAIA 2035 plan to become a 100% renewable and low-carbon energy hub by 2050, with active development of hydrogen infrastructure (650 km HySoW backbone with PCI status, 16.7% stake in the 400 km H2med/BarMar subsea pipeline targeting 2032 commercial operation), CO2 transport for CCUS (2.5 Mt CO2/year volumes secured), and biomethane injection (13 sites, 690 GWh/year capacity). The company is owned primarily by Italian TSO Snam (40.5%) and, as of April 2026, Spain's Enagás (31.5% acquired from Singapore's GIC for €674.65M), creating a strategic Southern European TSO bloc aligned around the H2med hydrogen corridor.
