The Core project parties are pleased to confirm the successful go-live of the Core Flow Based IDCC(e) process on 14 October 2026. This milestone marks the final flow-based intraday capacity calculation of the Core region and a big step towards the optimization of the available cross-zonal capacity for the intraday market.
The results of the IDCC(e) process will be published daily on the JAO Publication tool, accessible via https://publicationtool.jao.eu/coreID/
The IDCC(e) process delivers updated cross-zonal capacities by 16:00 to the Single Intraday Coupling (SIDC) market platform for MTU’s 18:00 – 24:00. Having a harmonized capacity calculation methodology in place in the Core CCR makes the European electricity system more efficient and robust. This harmonization thereby improves the capacity allocation in the Core CCR and enables the European power grid to transport more electricity across borders leading to lower overall cost. Furthermore, it allows for an improved cooperation between all involved parties. Finally, market participants will also benefit from further improved transparency of all capacity related data.
This milestone is the final step in the implementation of the sequence of flow-based intraday capacity calculation in the region and a big step towards the optimization of the available capacity for the intraday market while respecting operational security using the latest available CGM (common grid model).
The Core Flow-Based Intraday Capacity Calculation (Core FB IDCC) project promotes the development and implementation of a flow-based intraday capacity calculation across the whole Core Capacity Calculation Region (Core CCR) in the framework of the SIDC. The Core CCR consists of the bidding zone borders between the bidding zones of the following countries: Austria, Belgium, Croatia, Czech Republic, France, Germany, Hungary, Ireland, Northern Ireland, Luxembourg, the Netherlands, Poland, Romania, Slovakia, and Slovenia.
