Single Day-Ahead Coupling (SDAC) 15-Minute Products Set to Start Member Testing on 7 April 2025

SDAC Parties Confirm Start of Member Testing as Scheduled

The shift to a 15-minute MTU in the SDAC represents a major advancement in the evolution of Europe's energy markets. Scheduled to go live in June 2025, this new development will refine market operations by enhancing precision, improving the integration of renewable energy sources, and increasing overall efficiency and flexibility. By enabling better adaptation to fluctuations in energy supply and demand, it will support more accurate pricing and scheduling, delivering significant benefits to market participants.

The 15-minute MTU member tests will be conducted on dedicated test environments, as outlined in the below linked information, between April 7 and May 15. NEMOs and TSOs will monitor the testing experiences, with a particular focus on operations, efficiency, and results. While the member tests are underway, NEMOs and TSOs will continue to collaborate to further enhance process stability.
