Implementation of Core Advanced Hybrid Coupling (AHC) within SDAC
On 11 June 2026, the Advanced Hybrid Coupling (AHC) functionality was implemented within the European day-ahead electricity market (Single Day-Ahead Coupling – SDAC) for a subset of bidding zone borders between the Core region and the Baltic, Hansa, Nordic, and South East Europe (SEE) regions.
The objective of AHC implementation is to support a more coordinated and harmonized use of cross-border transmission capacities, contributing to a more efficient integration of European electricity markets.
The implementation became effective from the trading day of 10 June 2026 for the delivery day of 11 June 2026. In line with the agreed go-live process, project parties will closely monitor the performance and stability of the solution in the coming days.
From the perspective of Slovak market participants, no direct changes to day-ahead trading processes or order submission are currently expected. However, this implementation represents another step towards more efficient cross-border capacity utilization and deeper European market integration.
