[CWE flow based market coupling]: information on potential exclusion of lines 20% minRAM application

Dear market participant,

In light of CWE TSOs dialogue with market parties, please be informed about the following background about when TSOs exclude one or multiple critical branches from the 20% minRAM application.

• CWE TSOs rely on a complex verification system using several Models which anticipate on the results of the Market to ensure security of supply at all times and possible market outcomes;
• The verification system relies on many parameters, making it very difficult to pinpoint a single reason for exclusion;
• Market parties will be duly informed via an Urgent Market Message about exclusions should they occur;
• The flow-based domain and the respective parameters will be fully transparent in the morning before allocation of capacity takes place.

Best regards,
CWE TSOs
