Dear Market Participant,

During these past weeks, the French Electricity grid has witnessed severe constraints on its eastern borders. Starting from business day 11th of May 2024, RTE will no longer need to proceed to exceptional operational security measures on the capacity calculation processes of Core and Italy North regions.

On behalf of RTE
