11^th June 2019: The Day-ahead Joint Steering Committee has today initiated an in-depth investigation of the incident on the 7^th of June

• Since its launch in February 2014, more than 5 years ago, the Day-Ahead Multi Regional Coupling (MRC) has been operating successfully.
• On the 7th June an issue occurred which prevented the EPEX CWE and EPEX GB order books from being sent to the common coupling system.
• The incident was caused by an internal IT issue at EPEX and was not caused by the common market coupling algorithm.
• The issue could not be fixed in time and at 12:50 CET the market was informed about the partial decoupling of EPEX CWE, EPEX GB and consequently, following procedures and due to the geographical position of Iberia, of OMIE.  
• This triggered the execution of the agreed fallback procedures.
• Common coupling systems and procedures worked as expected, ensuring the coupling of the remaining part of MRC.
• The Joint Steering Committee has today initiated an in-depth investigation of the incident to identify lessons learned to mitigate the risk of similar incidents in the future.
