SEMOpx DAM Decoupling Deadline and Process Changes
08/06/22 (for Trade Date: 09/06/22)
Please be advised that there will be a change in the Partial and Full Decoupling deadlines and Full Decoupling Process in the Day-Ahead Market which will take effect on auction day 8th June 2022 (for Trade Date: 9th June 2022).
In the event of a full decoupling in the Day-Ahead Market, it will no longer be possible to re-open order books in order to run a second auction if the results of the first local auction after decoupling exceed predefined price thresholds.
This change in the process will provide an additional 20 minutes in the coupling process, which will help reduce the risk of partial and full decoupling in the Day-Ahead Market. As a result, the DAM Full Decoupling deadline will shift from 13:00 to 13:20 IST / GMT and the DAM Partial Decoupling deadline will move from 11:45 to 12:05 IST / GMT.
The SEMOpx Auction Timings and Market Messages document will be updated on the 8th June 2022 to reflect the above changes. The changes stated above are in line with Modification SPX_03_22 DAM Decoupling Deadline Changes.
