Your natural gas sourcing

GRTgaz network

The GRTgaz upstream network consists of a single entry/exit zone, the TRF (Trading Region France). There is a single PEG (virtual trading point). This is a virtual marketplace that allow gas to be freely exchanged, either through mutually-agreed bilateral exchanges (over-the-counter, OTC) or through exchanged performed on the Powernext Gas stock market.

What supply solution for your site?

To manage the sourcing for your site, GRTgaz overs several solutions appropriate to your needs: Integral, Active and Solo.


Accessing the PEG means access to nearly 3 times more suppliers than under the 'Integral' plan, to diversified supply offers and to the price of the wholesale gas market.

Under the 'Active' plan, the balance distributor balances your site: it supplies gas to match the difference between your gas purchases at the PEG and your actual consumption.

Under the 'Solo' plan, you provide your own balancing.

 A transmission contract made to measures

If you opt for the 'Active' or 'Solo' plan, you must sign a transmission contract with GRTgaz, in this way becoming a 'shipper'. This is a 'modular' contract, comprising optional sections depending on your profile.

Ensuring future availability of your capacity

To ensure the future availability of your transport capacities on the regional network, you can sign a CRAC (French: Advanced Reservation Contract for Transmission Capacity)

The CRAC determines the conditions under which:

  • GRTgaz undertakes to provide routing of natural gas over the regional network to supply your installations at the agreed date;
  • You undertake to ensure that you – or a distributor – subscribe, on this same date as part of one or more routing contracts, to the routing capacities reserved in this way for a period of 5 years;
  • You undertake to agree a connection and delivery contract for your site.

You are automatically eligible for the CRAC if the price for routing over the regional network and at delivery represents a sum greater than €200,000 excl VAT per year.

The CRAC must be signed no later than a deadline of four months after submission of the connection proposal by GRTgaz.

Transparent and non-discriminatory access to GRTgaz’s transmission system is open to all companies.


To become a shipper on GRTgaz’s network, you must be in possession of a supply licence, then sign a transmission contract with GRTgaz and provide a payment guarantee.

  • Natural gas supply licence

    You must be in possession of a supply licence issued by the French Ministry of Ecology if your company sells gas on French territory, including at the Virtual Trading Point (PEG). For end customers selling gas on an occasional basis to another end customer located in the vicinity, both must also file a “simplified” application according to the terms of Article 2 of the French Decree dated 19 March 2004 related to gas supply licences. Applications are to be filed with: 

    Ministère de l'écologie, de l'énergie, du développement durable et de l'aménagement du territoire
    Direction générale de l'énergie et du climat
    Direction de l'énergie/SD1- Marché de l'énergie et des affaires sociales

    More information is available on the Ministry’s site

  • Electronic signature of a transmission contract

    You must sign a transmission contract electronically. This contract includes a number of sections that depend on your activity on the GRTgaz network.
    More information on the transmission contract is available here.

    GRTgaz has deployed a project to computerise transmission contracts and invoices in order to secure and simplify the contractualisation process for contracts and amendments, and also to improve the invoicing process.The principle of the computerisation is to transfer contracts and amendments, sign them electronically and archive them by computer in a personal “safe” specific to each customer.Invoices are also sent electronically via the secure “safe”. 

    The computerisation of contracts offers many advantages:

    • Secure transfers,
    • Simplification of the contractualisation process,
    • Reduction in the costs of logistics,
    • Greater environmental protection,
    • Guarantee of legal validity,
    • Traceability of operations and transfers,
    • 24/7 availability of information and contracts.

     As part of the project, GRTgaz has signed a contract with Docapost (a subsidiary of the La Poste group). Docapost provides document archiving services and has entrusted the management of the secure site, electronic signatures and electronic certificates to two subsidiaries of the La Poste group:

    • Certinomis for the management of electronic certificates,
    • Seres for the secure website and management of electronic signatures.

    Computerisation project steps

    GRTgaz's new transmission customers must automatically sign their contracts electronically.For customers that are already GRTgaz customers, the computerisation process is currently in progress. 

    • First steps conducted simultaneously:
      • Obtain the electronic certificate (parties involved: the Customer and Certinomis)
      • Sign an agreement to certify the electronic signature (parties involved: GRTgaz and the Customer)
      • Configure your “safe” (party involved: GRTgaz)
    • Step 2:
      • Install software and provide information on the tool (parties involved: Customer, with its IT support [“administrator” right for the station required] and GRTgaz)
    • Step 3:
      • Validate and sign your first amendment to the transmission contract (parties involved: customer and GRTgaz)
      • View your transmission invoice (parties involved: Customer and GRTgaz)

    To access the contract computerisation site..

  • Payment guarantee

    To become a shipper, you must provide GRTgaz with a payment guarantee. This guarantee can be composed either of a first demand guarantee or a security deposit. If your company’s credit rating is good, it will be exempted from this guarantee.

    The amount of the guarantee depends on the capacity subscribed, but is equal to at least: 

    • One hundred thousand euros (€100,000) or
    • Twenty thousand euros (€20,000) if you have a gas supply licence referred to as “simplified’ (authorisation to conduct occasional natural gas purchase and sales transactions at Title Transfer Points to satisfy needs related to the activities of your own industrial sites).

     The methods to calculate the amount of the guarantee are described in Section A – General Terms and Conditions of the Transmission Contract.

  • Customs formalities, taxes and tariff contribution on transmission

    You must discharge your tax and customs obligations.

  • The “ATRT7 ” tariff

    The CRE published on January, 23rd 2020 its deliberation approving tariff of natural gas transmission system for GRTgaz and Téréga, the “ATRT7” tariff, entering into force from April, 1st 2020 for 4 years and yearly updated. The main objectives or the ATRT7 are:

    • the proper functioning of the gas market with simple, predictable rules and in continuity with previous tariffs.
    • controlling the evolution of tariffs: after the end of a cycle of major investments and in the context of a drop in capacity subscriptions on the transmission networks and the evolution of gas consumption up to 2030.
    • accompanying the energy transition: the tariffs give operators the means to accommodate biomethane in the networks and for research and development.
    • maintaining a high level of safety in gas infrastructure.

    The trajectory defined for the 4 years (2020-2023) is an average increase of 1.4% per year. The ATRT7 tariff is a continuation of the previous tariff, both in its methodology for determining and updating it and in its structure, however with some new features:

    • Introduction of a tariff term for biomethane injection that aims to take into account the operating costs (OPEX) of network reinforcements induced by location choices.
    • Identical evolution in interconnection tariffs (entry/exit points at the borders of transport networks) throughout France.

    The ATRT7 tariff includes evolutions proposed by GRTgaz in order to make the offer more attractive for customers with highly modulated and/or difficult to predict consumption. Examples include the reduction of winter monthly factors in January and February, the elimination of the second tranche of penalties for overruns, and the possibility of subscribing daily capacity intra-daily up to 2 p.m. on D.

    ATRT7 also develops the storage compensation implemented since April 1st, 2018 with a change in the formula for calculating the base of T4/TP customers in distribution on April 1st, 2020 and an extension to customers connected to the transmission network from April 1st, 2021.

  • Composition of the tariff

    The tariff terms depend on the subscription period. Each contractual point is related to a tariff term.

    • Transmission on the upstream network: 
      The natural gas transport on the principal network consists in, for GRTgaz, removing the gas provided by a shipper in one or more entry gas points in France and in delivering it in one or more exit points. At each entry and exit points correspond a regular tariff. The main tariff terms are as follows:
      • Term of entry capacity on the main network (interconnection points with other transmission networks and LNG terminals) 
      • Term of exit capacity at interconnection points with other transmission networks
      • Term of entry and exit capacity for storage facilities
      • Term of link capacity between balancing zones
    • Transmission on the downstream network:
      The transport tariff on the regional network is proportional to the transport distance (NTR: level of regional pricing system).
      The NTR is fixed for each site. It is established according to the natural gas transport price on the regional network that is from the principal network to the start (or feet) of your connection.
      A site directly linked to the principal network, has a NTR that is 0.
      Finally, at the delivery, the pricing system is fixed according to the nature of installation (site high modulated or not) and according to the number of delivery stations.

      Thus, the tariff related to the delivery has 2 terms:
      • The delivery capacity term (TCL), which is proportional to the delivery capacity subscribed. 
      • The fixed delivery term (TFL). Determined annually, it is proportional to the number of delivery stations.

      For the sites present on the supply network, the tariff related to the delivery includes a term for the delivery of all the PITD (Interface Transport Distribution Points): The delivery capacity term (TCL), which is proportional to the delivery capacity standardized assigned to each PITD shipper concerned.
  • Tariff simulation tool

    The tariff tool allows you to calculate the main terms of the current tariff but also of the previous years.

  • Determination of tariffs

    The main legislative and regulatory texts governing transmission tariffs are as follows:

    • French Energy Code, Articles L. 452-1 to L.452-6; 
    • Decisions of the “Commission de régulation de l’énergie” (Energy Regulatory Commission) relating to the the tariff for use of the natural gas transmission networks from 1st April of each year.

    Article L. 452-3 of the French Energy Code provides that the Energy Regulatory Commission passes on to the Ministers in charge of energy and the economy its decisions, along with related grounds, relative to the evolutions in level and in structure of the tariffs for using the natural gas transmission networks […] as well as the tariff rules and their effective date. 

    These deliberations are published in the Gazette of the French Republic. Within two months of the receipt of its transmission, each of the concerned Ministers can, if the Minister considers that the decision of the Energy Regulatory Commission did not take into account the orientations of the energy policy, ask for a new decision, further to a motivated resolution published in the Gazette of the French Republic.

You are starting-up a new process

You are on the verge of starting trials for your new process and you need additional daily capacity, without certain knowledge of the days you will use it.

The trial service on consumer delivery points
enables you to use a daily delivery capacity package subscribed by you or your distributor.

You would like to consume a renewable energy without having to make profound changes to your facilities? Have you thought about biomethane?
Resulting from the transformation of organic matter, biomethane is the first renewable energy for gas / gas renewable energy.
To find out more: Biomethane, a renewable gas

Biomethane is an asset for both companies and local governments.
Consumption of biomethane in your industrial site - This green gas has several advantages: it allows you to reduce your CO2 emissions, to offer bio-sourced products to your proper clients and to improve your image.

To do so, here is how to proceed: 

Biomethane ensures gas consumers to use renewable energy without having to change their facilities and while still having the advantages of natural gas.  

Wherever you are located, you can buy green gas from a natural gas supplier who will have purchased it first from a producer at a 15-year State guaranteed feed-in tariff. A system of guarantees of origin (GO) ensures the product's full traceability and dissociates the strict consumption of biomethane molecule from the contractual sale to a client.

Clients as Carrefour, Ikea, Monoprix, Biocoop and Picard are already using biomethane fuel - also called bioNGV - for their logistics fleets. Other companies or local governments have chosen green gas: Terreal in Chagny to product tiles, Cofely for its heat network in Outreau, or the Bourg-en-Bresse city for its municipal facilities.
