The SDAC parties are pleased to confirm that the 15-minute MTU in the Single Day-Ahead Coupling (SDAC) has successfully gone live on 30 September 2025, for delivery day 1 October 2025.
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.
“We are delighted with the successful rollout of the 15-minute market time unit in the European Day-Ahead markets. This marks one of the most significant changes in market history and illustrates the immense value behind coordinated innovations.” — André Estermann, MCSC TSO Co-Chair.
“We remain committed to delivering reliable operations and upholding confidence in the system. We are grateful for the collaboration among all stakeholders — including NEMOs, TSOs, regulatory bodies and market participants — which has enabled us to realise this important achievement.” — Cosimo Campidoglio, MCSC NEMO Co-Chair.
This implementation aligns with the Clean Energy Package (CEP) and brings us closer to a smarter and greener energy system.
About SDAC
SDAC allocates scarce cross-border transmission capacity in the most efficient way by coupling wholesale electricity markets from different regions through a common algorithm, simultaneously taking into account cross-border transmission constraints, thereby maximizing social welfare. The aim of SDAC is to create a single pan European cross zonal day-ahead electricity market. An integrated day-ahead market increases the overall efficiency of trading by promoting effective competition, increasing liquidity, and enabling a more efficient utilization of generation resources across Europe.
