The Single Day Ahead Coupling (SDAC) parties, would like to invite all interested parties to SDAC decoupling training session, which will be held on 3 November 2021.
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 two 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.
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.
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).
