How to become a shipper

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 Title Transfer 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 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 Guarantee amount is revised in April and October and is equal to the highest of:

    • The above mentioned amount
    • The sum of the 2 highest amounts invoiced between the M-12 and M-1, notwithstanding the Balancing provisions
    • The sum of the 2 highest monthly amounts of the capacity portfolio value in the next 6 months

    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.
