SDAC decoupling - training session
Single Day Ahead Coupling (SDAC) parties would like to invite you to an SDAC decoupling training session, which will be held on 30/09/2020.
Since the Go-Live of Multi Regional Coupling (MRC, i.e. the predecessor of SDAC) in 2014, almost 2400 successful market coupling sessions have been conducted. In the last 15 months, 2 major incidents have happened that led to a partial decoupling of the SDAC Market. As part of the SDAC evaluation of these two incidents, a recommendation was made to perform training sessions involving all operational parties (Transmission System Operators, Nominated Electricity Market Operators, Central Clearing Parties, Shadow Auction entities, etc.) including Market Participants. In addition, EFET & EURELECTRIC on behalf of the Market Participants have requested for a realistic decoupling training session.
This training session is organized to give all parties involved in a possible Day Ahead market decoupling the opportunity to validate that they are properly prepared to handle such an incident in real operations and real-life conditions.
A full decoupling due to issues with the central calculation process will be simulated. This means that no MRC market coupling results will be available, but local auctions/regional coupling will be triggered depending on the specific region. For your convenience, the session will take place outside of the usual MRC timings in order not to interfere with ongoing operations.
The TSOs, NEMOs, and JAO (Joint Allocation Office) will handle the situation in line with operational procedures, especially shadow auctions will be run by JAO and local auctions by the NEMOs after the Full Decoupling. Market participants are expected to respond and act, based on the operational messages from their respective NEMOs and JAO, exactly like in real operations. The complete process chain will be addressed (incl. nomination and matching).
The entire training session will take place in a simulation environment. All operational messages from involved parties will be clearly marked as "SIMULATON" messages. Please make sure that in any case, if you are participating or not, your staff present on 30/09 will be aware that this test is scheduled and that messages related to it are sent out. This is important to prevent any type of misunderstanding that could impact the processes in production.
- 16/09: Distribution of detailed information package to the Market Participants
- 24/09: Market Participant registration deadline towards its NEMO/JAO
- 30/09: Execution of the full decoupling training session
An assessment and feedback session will be scheduled following that training session.
