Congratulations to SDAC TSOs & NEMOs on this key achievement! As of delivery day October 1 Single Day-Ahead Coupling (SDAC) supports allocations with 15-minute granularity.

The introduction of 15-minute Market Time Unit marks a major step forward. By improving trading granularity, this milestone enables a more precise alignment between energy generation and consumption, reducing imbalances and strengthening grid reliability.

With shorter trading periods, market participants can reflect the nature of production/consumption which varies within an hour – minimizing imbalance penalties and adjustment costs. Better pricing and resource allocation ensure trades accurately reflect market conditions.

This market evolution is especially crucial for integrating renewables like wind and solar, whose output fluctuates more than conventional generation. Greater flexibility means less reliance on fossil fuels, supporting a more sustainable & resilient energy system.

Beyond operational benefits, the 15-minute market is set to boost economic efficiency, increase market liquidity, foster competition, and attract new participants.

For over 10 years, E-Bridge Consulting has been supporting European NEMOs & TSOs in the design & implementation of Single Day-Ahead Coupling (SDAC) & Single Intraday Coupling (SIDC). Today, these platforms enhance cross-border trading across 25+ countries, benefiting a total population of over 440 million.
