The transition to the 15-minute Market Time Unit (MTU) in the Single Day-Ahead Coupling (SDAC) marks a significant milestone in the evolution of Europe’s energy markets. Following a reassessment of the implementation plan by NEMOs and TSOs, the new go-live date for the 15-minute MTU implementation is set for 11 June 2025 with delivery date of 12 June 2025. To secure the continuity of the day ahead coupling, and taking into consideration market participants’ suggestions, NEMOs and TSOs have agreed to follow the go-live with a short rollback period of one week.
