Operational Information

General Framework

In order to subscribe transmission services, a party must first register as a grid user.

Once registered as a grid user, requests for transmission services can be submitted and at the same time grid user can prepare its operational readiness.

  • In the BeLux area grid users are sending nominations to the respective TSOs in Belgium (Fluxys Belgium) and in Luxembourg (Creos Luxembourg).
  • Confirmations and detailed allocations per interconnection point or domestic exit point will be received from the relevant TSO.
  • Fluxys Belgium and Creos Luxembourg will provide the Balancing Operator of the BeLux area (Fluxys Belgium) with aggregated allocation data of their grid per individual grid user.
  • The Balancing Operator will provide each grid user with its individual and the market balancing data (aggregated data of all grid users) of the entire BeLux area.
