Dear SEMOpx Member,
The SDAC parties are pleased to confirm that the 15-minute MTU in the Single Day-Ahead Coupling (SDAC) / 30-minute MTU in the SEM has successfully gone live on 30 September 2025, for delivery day 1 October 2025 (with the Rollback Activation Period now passed).
The transition to 15-minute MTU in Europe’s electricity markets marks a significant advance in market efficiency and flexibility. This milestone enhances the precision of supply and demand matching, which is increasingly vital as renewable generation introduces greater variability. By enabling more dynamic responses to short-term fluctuations, the new granularity supports the seamless integration of renewables, reduces reliance on fossil fuels and reinforces the commitment to advancing Europe’s energy transition.
This implementation aligns with the Clean Energy Package (CEP) and brings us closer to a smarter and greener energy system.

Kind regards,
SEMOpx Team
