ISOT 4/8/2026 (POST_ExC_03a): Further information on the Risk of Partial Decoupling Short term market results
Dear Market Participant,

You have received earlier today a communication regarding a risk of Partial Decoupling. This message was sent at 12:40 to warn you that certain areas had a risk of being decoupled.

The Operations teams managed to ensure that the issue was solved before the Partial Decoupling deadline of 13:05.

This has led however to a delay in the publication of the Market Coupling Results.

We would like to inform you that the next Market Coupling Session is expected to be run under normal circumstances.

We apologize for any inconvenience that this delay may have caused and we thank you for your understanding.
