Your supply

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 allows 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 network?

To manage the sourcing for your network, 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 network: 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 'distributor'. This is a 'modular' contract, comprising optional sections depending on your profile.

View all sections of the transmission contract.

Become a distributor

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.

  • A management 100 % dematerialized

    Once you have become a shipper, you will be authorised to access the private customer portal, Trans@ctions, which allows you to:

    • reserve your transmission capacity and related services,
    • proceed with your nominations,
    • and have access in real time to the tracking of your operational activity.

Price and pricing tool

  • Rates applicable as of 1st April 2017

    The CRE published on December, 15th 2016 its deliberation approving tariff of natural gas transmission systems of GRTgaz and TIGF, the “ATRT6”, that will enter into force from April, 1st 2017 for the next 4 years. This new tariff frame allows GRTgaz to face major goals during this time frame without overcharging its transmission costs : achieve the single marketplace in France in 2018, promote natural gas and develop future energy solutions.

    ATRT6 tariff underlines major evolutions on the “downstream” offer concerning the regional network and the new conditions to connect consumers and distributors to its network.

    First of all, ATRT6 tariff takes into account the reprocessing of charges transfer due to repair maintenance, renovation and replacement (the “3R” operations), between the distribution networks and GRTgaz following the deliberation of the CRE published in March, 10th 2016.

    Then it introduces as well measures to promote new customers connections and to maintain existing customers, while controlling transmission costs. To do so, 2 new offers will be available from April, 1st 2017 :

    • a “development discount” : it will allow to reduce financial costs due by industrial customers, distribution network operators or projects of NGV or bioNGV stations to connect them or develop existing facilities,
    • the limitation of the “Niveau de Tarif Régional » (NTR). The NRT will be limited to 10 (currently up to 29), in order to preserve competitiveness of the most remote sites from GRTgaz’ network and to prevent from any termination of their connection to its network.

    2017 Tariff terms

  • Rates applicable as of 1st April 2016

    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 terms are available the downloadable file here and in SmartGRTgaz website.

    GRTgaz also provides a tariff simulation tool.

  • 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.
