[Urgent market message publication] MinRAM Exclusion

by Réseau de Transport d’électricité S.A.

Dear Market Participant,

For business day 2021-09-15, following the security assessments it was concluded by RTE that the 20% minRAM could not be applied for all lines, which might impact the available capacities for the CWE day-ahead market coupling compared to the situation where the 20% minRAM would be applied.

We trust to have informed you sufficiently and in due time.

Best regards,

RTE - Réseau de Transport d’électricité S.A.

Dear Market Participant,

For business day 2021-09-15, following the security assessments it was concluded by RTE that the 20% minRAM could not be applied for all lines, which might impact the available capacities for the CWE day-ahead market coupling compared to the situation where the 20% minRAM would be applied.

We trust to have informed you sufficiently and in due time.

Best regards,

RTE - Réseau de Transport d’électricité S.A.
