Dear Member,

On Monday, 19th September 2022, the ETS trading system will not be available due to an ad hoc maintenance work from approx. 18:40 BST until 22:30 BST.

Price increase will be implemented on the SDAC auction from 4000€/MWh to 5000€/MWh.

All orders for ROI in the SEM-DA auction (Linear and Complex) will be deleted and members will need to re-enter after the maintenance.

The IDA 1 / 2 / 3 auctions will remain unimpacted.

The go-live date for implementation on the SDAC auction is 20 September 2022 (first trading day) for delivery date 21 September 2022.

Members are advised to start the Trading Limit increase process if needed.

During this timeframe, it will not be possible to connect to the ETS Trading System.

Please inform your colleagues about this maintenance and contact us on our hotline (option 1) for any questions you may have.

Kind regards,

SEMOpx Team
