Successful go-live of the Core Flow-Based Intraday Capacity Calculation IDCC(a)


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 following EU Member States’ bidding zones: Austria, Belgium, Croatia, Czech Republic, France, Germany, Hungary, Luxemburg, The Netherlands, Poland, Romania, Slovakia and Slovenia.

The Core project parties are pleased to confirm the successful business go-live of the Core Flow Based IDCC(a) process on 13 June 2024 for trades on business day 14 June 2024.

The IDCC(a) process delivers the left-over capacities from day-ahead by 14:45 towards SIDC for usage in the first intraday auction taking place at 15:00. With the go-live of IDCC(a) the opening of the cross-border intraday market in Core thus advances from 22:00 to 15:00 for the full 00:00 – 24:00 timespan of the subsequent business day. The results of the IDCC(a) process will be published daily on the JAO Publication tool, accessible via
