An unforeseeable technical issue was experienced leading to a partial decoupling of GME’s order book during the market coupling process on the 13 January 2021. The incident was caused by a technical issue and was not caused by the common market coupling algorithm (Euphemia).
As a consequence, the partial decoupling of GME’s order book was declared and explicit auctions were triggered for the impacted interconnectors. The following PCR areas and interconnectors were decoupled from SDAC:
GME: IT-AT, IT-FR, AT-SI, IT-SI, SI-HR GME – EXAA – CWE: None HENEX: GR-IT
Immediately after such event, results of a new session of the Italian day-ahead market have been calculated. Moreover the common coupling system worked as expected and ensured the coupling of the remaining European market areas within SDAC. GME has initiated an in-depth investigation that led to the identification of the problem that has been then positively fixed.
