SDAC PRESS RELEASE18.06.2026Successful Deployment of Core Advanced Hybrid CouplingTransmission System Operators (TSOs) and Nominated Electricity Market Operators (NEMOs) are pleased to confirm the successful rollout of Advanced Hybrid Coupling (AHC) for a subset of bidding zone borders between the Core Capacity Calculation Region (CCR) and the Baltic, Hansa, Nordic, and South East Europe (SEE) CCRs within the Single Day-Ahead Coupling (SDAC). This milestone represents a meaningful step in the continued development and integration of the European electricity market. It was made possible through close and constructive cooperation between the Core CCR governance—supporting the implementation of AHC on its borders—and the SDAC governance, ensuring its smooth integration into the day-ahead market. Careful preparation for a smooth implementationThe Advanced Hybrid Coupling approach, first introduced in the Nordic CCR and now extended to the Core CCR, supports a more efficient integration of Core external borders. By enabling a more coordinated and harmonized use of cross-border capacity, it contributes to improving consistency in how electricity exchanges are managed across regions and throughout Europe. The implementation has been carefully prepared over the past months to ensure that market coupling systems can accommodate the change while maintaining stable and reliable performance. Advancing market integration through collaborationThe solution went live on 10 June 2026 (trading day), for delivery day 11 June 2026, and has been operating as expected since. TSOs and NEMOs would like to express their appreciation to all parties involved in making this possible, and in particular to ACER and the European Commission for their continued guidance and support throughout the process. This achievement reflects a shared commitment to gradual, coordinated progress toward a more integrated European electricity market. About SDACSDAC 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.
