A local grid at the heart of European gas exchanges

A local grid at the heart of European gas exchanges

Established in 15 departments in the far South-West of France, Teréga occupies a strategic position in the regions and in the heart of Europe. Its grid, with a dense local network interconnecting with foreign networks, plays a key role in meeting the French and European energy challenges.

Our grid speeds up energy transition in the regions

By 2030, renewable energy will make up at least 33% of final energy consumption, according to the targets in the Energy and Climate Law enacted on 8th November 2019. Article L6100.2 of the Energy Code also stipulates that renewable gas make up a 10% share of gas consumption in 2030. A new geographical distribution of resources is emerging: production premises are based in the regions, and regional and territorial communities are the prime movers of energy transition.

Teréga supports these changes in the heart of the French regions. We rely on a local, flexible and responsible grid to develop transport and new uses for gas. Strongly established in the regions, we support the emergence of local biogas production facilities. We are also working to enable our grid to accept other renewable and decarbonised gases such as the hydrogen originating from renewably generated surplus electricity.

Our mastery of the gas industry enables us to speed up:

  • the development of interconnections between these new production premises and local, national and European centres of consumption.

  • the emergence of intelligent multi-energy systems to optimise energy consumption and the relationships between producers and consumers.

Teréga at the heart of the European gas network

In a marketplace experiencing full-scale transformation, Teréga is helping build a carbon-neutral energy system in response to the climate challenge. Interconnected with other European networks, we capitalise on our infrastructures and our capacity to transport green gases to supply a large part of the national and European territory.

To that end, Teréga has developed a close working relationship with key actors in the sector. We have made commitments within associations and organisations working on the great challenges facing the sector and the future of energy to meet French and European targets on energy transition.

For example, in 2020 we worked with ten other European gas infrastructure managers to put together a plan to create a European Hydrogen Backbone. Over time, two complementary gas transport networks could thus emerge in Europe: the first dedicated to transporting hydrogen, and the second to transporting biomethane.

European bodies of which Teréga is a member


Announced with the European industrial strategy, the European Clean Hydrogen Alliance (or ECH2A) was officially launched alongside the European hydrogen strategy in the summer of 2020. 

By structuring the industry and bringing forward practical projects, the Clean H2 Alliance aims to guide and coordinate the rise of the use of clean hydrogen in Europe, bringing industries in the sector and the Commission together. By establishing a reserve for investment projects, the Alliance will play a crucial role in helping reach the target of climate neutrality in 2050, driven by the Green Deal.

Gas for Climate

Established by the main European gas infrastructure operators and biomethane producers, the Gas for Climate (GfC) consortium has demonstrated through its work that the development of biomethane and hydrogen, based on the gas infrastructures, will enable energy transition at the least cost, through a sectoral integration approach, and creating new jobs.A number of GfC members are also behind the European Hydrogen Backbone initiative.

(European Network of Transmission System Operators for Gas)

The role of ENTSOG is to strengthen cooperation between European gas transport network operators to allow the development of a European transport system in harmony with the European Union’s energy targets. Its aims are to stimulate cross-border exchanges, to guarantee the effective management and coordinated operation of the European gas network, and to facilitate the technical evolution of infrastructures. ENTSOG also has a role to play in the planning of infrastructures, linked to the market’s needs.

(European Gas Research Group)

The GERG works with the European energy community to meet the challenges facing the gas industry: reducing greenhouse gas emissions and developing renewable gases. Its aim is to maintain energy security and competitiveness in Europe, while at the same time finding the cheapest possible route for energy transition.

(Gas Infrastructure Europe)

GIE is an independent association bringing together industrial players in the European gas infrastructure. Its job is to facilitate investment by offering, through Europe, a stable regulatory framework which encourages security of supply and competition. It has 70 members in 26 European countries, whose activities are: managing gas transport grids, managing gas storage systems, and operating methane tanker terminals.

National organisations of which Teréga is a member

Founded in 1874, the France Gaz is the professional body representing the gas industry in France, covering natural gas, biomethane, biogas, hydrogen and LPG. It acts as a representative for activities in the sector before the public authorities, and contributes to the drafting of laws and regulations. France Gaz also contributes to European and international work on the issue.

(Association Française du Gaz Naturel Véhicule, the French association for natural gas for vehicles)

The AFGNV’s mission is to support the development of natural gas and renewable gases as vehicular fuels (NGV and BioNGV) in France. It brings together public, economic and industrial players.

(Association Technique Energie Environnement, the Energy and Environment Technical Association)

The ATEE comprises a diversity of members (businesses, local authorities, teaching establishments etc.), all of whom are involved in managing energy and its impact on the climate. It helps its members introduce practical solutions in that regard.

The strategic committee for the new energy systems industry

The objective of the Comité Stratégique de Filière is to establish a concrete, effective and regular dialogue between the State, businesses and employees’ representatives on key subjects in the sector.

The CSF is the French authorities’ go-to spokesperson for industrial policy.

Teréga and GRTgaz chair a joint forum for consultation with all actors in the market. That forum is in addition to the process of listening to the market in which natural gas transporters are already engaged.

It satisfies the following objectives:

  • to provide forums for consultation shaped and organised according to common operating rules,

  • to constitute a dynamic offer of products and services to match market needs as closely as possible,

  • to allow each of the actors (CRE, transporters, shippers, customers) to occupy a position that is consistent with their role within the market.

Open Data Energy Networks

Open Data Réseaux Énergies (Open Data Energy Networks, or ODRÉ) provides stakeholders with data on topics such as “Production”, multi-energy “Consumption” (gas and electricity), “Storage”, “Mobility”, “Territories and Regions”, “Infrastructures”, “Markets” and “Meteorology”, all provided through the combined expertise and know-how of Réseaux Énergies members.

Created in January 2017, the aim of Réseaux Énergies is to incorporate new multi-energy, multi-operator and multi-network data, but also to expand with the addition of new actors hoping to share in a process that combines transparency with education for the public, local authorities and economic actors, all with a view to contributing to the development and assessment of energy policy.

Réseaux Énergies is the fruit of a partnership between GRTgaz, RTE and Teréga, who were behind its creation. Since then they have been joined by AFGNV, Weathernews France, Elengy, Storengy and Dunkerque LNG.
