SDAC Decoupling training session with Market Participants 03/11/2021 – Common invitation
Dear Market Participants,
Hereby, the Single Day Ahead Coupling (SDAC) parties would like to invite you to an SDAC decoupling training session, which will be held on 03/11/2021.
BACKGROUND
Since the go-live of Multi Regional Coupling (MRC, jointly with 4M MC forming SDAC) in 2014, more than 2,700 successful market coupling sessions have been conducted. In the last 2 years, three major incidents have happened that led to a partial decoupling of the SDAC Market. As part of the SDAC evaluation of these three incidents, recommendations have been made to perform training sessions involving all operational parties (Transmission System Operators [TSOs], Nominated Electricity Market Operators [NEMOs], Central Clearing Parties, Shadow Auction entities, etc.) including Market Participants.
OBJECTIVE
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 market decoupling incident in real operations and real-life conditions.
SCENARIO
A full decoupling due to issues with the central calculation process will be simulated. This means that no SDAC 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 SDAC operational timings in order not to interfere with ongoing operations.
The TSOs, NEMOs, and the Joint Allocation Office (JAO) will handle the situation in line with operational procedures. More specifically, shadow auctions will be run by JAO and local/regional coupled auctions will be run 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, unless explicitly stated otherwise in respective regions).
PLEASE NOTE
The entire training session will take place in a simulation environment. All operational messages from involved parties will be explicitly marked as "SIMULATION" messages. Please make sure that your operational staff present on 03/11/2021, whether you are participating or not, is 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.
NEXT STEPS
- 06/10: Distribution of detailed information package to the Market Participants
- 20/10: Market Participant registration deadline towards its NEMO/JAO
- 03/11: Execution of the full decoupling training session
- 10/11: Collection of market participants’ feedback on the training session
Looking forward to a productive and constructive session together,
OKTE, a.s.
