Core project parties have confirmed the go-live of the final step in the sequence of flow-based intraday capacity calculations on 14 October 2026.

Following the successful external parallel run, Core project parties have confirmed the go-live of the IDCC(e) capacity calculation process for business day 14 October 2026.

The IDCC(e) process will provide updated cross-zonal capacities to the Single Intraday Coupling (SIDC) for the 18:00–24:00 market time units. Its implementation marks the final step in the sequence of flow-based intraday capacity calculations in the Core region, supporting a more efficient use of available cross-zonal capacity and further strengthening European market integration.
