Transition to 15-Minute MTU for SDAC

Published:

Dear Market Participant,

As part of the upcoming transition, our Publication Tool will be updated to support 15-minute Market Time Unit (MTU) products under the Single Day-Ahead Coupling (SDAC).

Please find attached an example files for the Price Spread (CORE and IBWT), showcasing the new 15-minute resolution format.

Where a resolution change is applicable, the only difference in the files will be the number of positions (96 instead of 24).

We will be sharing a full overview of changes planned for Publication Tool in the scope of this transition at a later stage.

Please note that there will be no change to JAO Auction Tool (eCAT) files:

  • Incoming/outgoing files from the JAO Auction Tool (eCAT) will remain unchanged and will continue to use 60-minute MTU resolution;
  • Settlement files will also remain unchanged, except for the compensation calculation method, which is detailed in the attached Information System Rules Appendix 9;
  • Shadow auctions will remain in 60 min MTU.
