Postponement of the Core Flow-Based Market Coupling project Go Live

Core project parties concluded that the Core go-live planned for 20 April 2022 must be postponed as a go-live on this date could not be supported by some Core project parties.


The main concerns expressed are:

  • The timing of the Core FB DA go-live considering the current market context - in combination with the other concerns listed below
  • The not sufficiently demonstrated stability of the DA pre-market coupling process in Flow-Based DA capacity calculation, and the impact on capacities when fallbacks need to be applied
  • The impact on ID ATC capacities, the methodology will be known in mid-April and the need for TSOs to develop tools for maximising capacities while maintaining system security
  • The issue of undue discrimination triggered by too low capacities provided on critical network elements


Core project parties will monitor the operational stability of the external parallel run closely during the coming weeks and work in parallel on concrete plans to deal with these concerns in a timely manner.


Core Project parties will communicate a new go-live date as soon as the concerns are managed and alleviated.
