•Countries/Bidding zones decoupled from the SDAC auction: Czech Republic
•Interconnectors decoupled from the SDAC auction: CZ-AT, CZ-DE/LU, CZ-SK, CZ-PL
•Order book decoupled from the SDAC auction: OTE (CZ)
The incident was caused by local issues at OTE Local Trading System preventing the order books from OTE to be submitted before the operational deadline of partial decoupling. Hence, a partial decoupling was declared at 13:05 CEST in line with the relevant procedures.
The robust organization of market coupling worked as expected and ensured the coupling of the remaining part of the SDAC topology. The final SDAC market coupling results were published around 14:15 CET/CEST
Due to the OTE local issue, OTE was also decoupled from IDA 3 at 10:00 CEST and from IDA 1 at 15:00 CEST. Further NEMOs were decoupled from IDA 1 at 15:00 CEST following the SDAC Partial decoupling. Summary on IDAs will be provided in the weekly dedicated reports.
The MCSC has initiated an in-depth investigation. A decoupling report summarising the outcome of the investigation and potential lessons learned is expected to be published within 4 weeks’ time.
