    Step 1 – Non-binding demand indications

    Parties interested in incremental capacity can submit non-binding demand indications at any time. However in the 2021 market demand assessment, Fluxys considered non-binding demand indications submitted no later than 30 August 2021 (cob). Non-binding demand indications received after this deadline will be considered in the next market demand assessment – in 2023.

    Non-binding demand indications can be submitted using the non-binding demand indications templates:
