Market Coupling Steering Committee Aligns on Revised Go-Live Date for 15-Minute MTU in SDAC

Go-Live Rescheduled from 11 June to 30 September 2025

As part of NEMOs’ and TSOs’ ongoing commitment to delivering a robust solution for the European market, project parties verified that performance tests of the joint systems and procedural tests have been successfully completed. Tests with market parties were on good track, and most of the project parties were technically ready for the scheduled golive of 11 June 2025.

However, due to the non-technical readiness of some parties, the project parties, within the project’s governance framework, announce the postponement of the golive of the 15-Minute Market Time Unit (MTU) project in SDAC to 30 September 2025, first trading date, for delivery date 1 October 2025. Alternative go-live scenarios were considered (including technical feasibility), but the timeline for implementation cannot be accommodated.

The updated detailed planning will be shared at the upcoming Market Coupling Consultative Group (MCCG) and Market Stakeholder Committee (MESC) meetings on 2 June 2025 and 3 July 2025.

While project parties will continue testing to support readiness and robust market conditions, market participants are still encouraged to join the testing to familiarize themselves with simulated scenarios and ensure full preparedness for the go-live.

NEMOs and TSOs appreciate all stakeholders’ continued efforts and collaboration.
