Over the years, the number of coupled countries and consequently the number of parties and systems involved in the Single Day-Ahead Coupling (SDAC) has increased enormously. As a result, the market coupling process and especially, the calculation process, has become more complex.
To secure that there is sufficient time for running the daily market coupling process, the National Regulatory Authorities (NRAs) have approved the joint proposal of Nominated Electricity Market Operators (NEMOs) and Transmission System Operators (TSOs) to increase the maximum duration of the algorithm calculation from 12 to 17 minutes and to change the corresponding deadlines enabling NEMOs and TSOs to find a solution for avoiding decoupling.
For market parties this will result in the following changes in the daily operational timings:
- Preliminary Results publication time: 12:45 CET (instead of 12:42 CET)
- Partial-Decoupling due to missing order books deadline: 12:45 CET (instead of 12:40 CET). Reopening of order books for coupled and decoupled areas after a PartialDecoupling is announced will be extended from 10 to 15 minutes.
- Full-Decoupling deadline: 14:00 CET (instead of 13:50 CET)
- Publication of Shadow Allocation Results: no later than 14:00 CET (instead no later than 13:50 CET). This deadline is only relevant where Shadow Auctions are the Fallback solution in place. The corresponding rules have been updated as published by JAO here: jao.eu.
The implementation of the new operational timings will take place on 17 June for the delivery day 18 June 2021 together with the Interim Coupling Project go-live, the latter being subject to confirmation of technical and legal readiness by all parties.
About SDAC
SDAC allocates scarce cross-border transmission capacity in the most efficient way by coupling wholesale electricity markets from different regions through a common algorithm, simultaneously taking into account cross-border transmission constraints, thereby maximising social welfare. The aim of SDAC is to create a single pan European cross zonal day-ahead electricity market. An integrated dayahead market increases the overall efficiency of trading by promoting effective competition, increasing liquidity and enabling a more efficient utilisation of generation resources across Europe.
