Hereby, the Single Day Ahead Coupling (SDAC) parties would like to invite you to an SDAC decoupling training session, which will be held on 20/03/2024.

Since the go-live of Multi Regional Coupling (MRC, jointly with 4M MC forming SDAC) in 2014, more than 3,600 successful market coupling sessions have been conducted. In the last 10 years, five major incidents have happened that led to a partial decoupling of the SDAC Market.

As part of the SDAC evaluation of these incidents, recommendations have been made to perform training sessions involving all operational parties (Transmission System Operators [TSOs], Nominated Electricity Market Operators [NEMOs], Central Counter Parties, Shadow Auction entity, etc.) including Market Participants. This training session is organized to give all parties involved the opportunity to validate that they are properly prepared to handle such a day-ahead Full Decoupling incident in real operations and real-life conditions following simulation timings.

Next steps regarding the training session:

• 15/02: Distribution of detailed information package to the Market Participants
• 13/03: Market Participant registration deadline towards its NEMO & JAO
• 20/03: Execution of the full decoupling training session
• 27/03: Collection of market participants’ feedback on the training session
