SDAC 15-Minute MTU Members’ Test organisation

by JAO

Dear Market Participants,

Please find attached the nomination information related to the member tests for the SDAC 15MTU project.

As communicated by the TSOs and NEMOs, member tests will begin on 7th April 2025. During the first week of these simulation tests, both partial and full decoupling tests will take place, and TSOs will facilitate testing of the nomination process. The attached table provides details on the borders where shadow auctions will be organized, the resolution used for nomination rights documents, and the nomination deadlines.

To ensure a smooth nomination process, we strongly recommend that you contact the TSOs to confirm they have all necessary information. While JAO has already provided the TSOs with your company name and EIC code, they may also require your system’s email address and testers’ contact details.

For normal days, the nomination will follow production processes and will therefore be handled by CCPs.

Should you have any questions, please do not hesitate to contact us.

Kind regards,

JAO Operations
