Market Coupling Steering Committee

The Market Coupling Steering Committee (MCSC) provides more information to the partial decoupling of the Single Day Ahead Coupling (SDAC) taking place on 24 July 2024 (for delivery date 25 July 2024).

• Countries/Bidding zones decoupled from the SDAC auction: the Czech Republic
• Interconnectors decoupled from the SDAC auction: CZ-AT, CZ-DE/LU, CZ-SK, SK-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 from being submitted before the operational deadline. The problem could not be fixed within the time allocated by the SDAC procedures and a partial decoupling was declared at 13:05 CEST in line with the relevant procedures.

As a consequence of this local issue, OTE was also decoupled from IDA 3 at 10:00 CEST and IDA 1 at 15:00 CEST according to the operational procedure. Further NEMOs were decoupled from IDA 1 at 15:00 CEST following the SDAC Partial decoupling.

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 at 14:15 CET/CEST. The results of the decoupled Czech day-ahead market were calculated afterwards. The operation of following intraday auctions and day-ahead market on 25 July 2024 (for delivery day 26 July 2024) were run according to standard procedures.

The official communiqué of MCSC is available here.

We apologize for any inconvenience caused by this partial decoupling of the Czech day-ahead market.
