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

Date: 13-06-2024

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.

This milestone is the next step for European market integration in the Core region, following the go-live of IDCC(b) on May 28.

The IDCC(a) process delivers the left-over capacities from day-ahead by 14:45 towards SIDC for usage 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 https://publicationtool.jao.eu/coreID.

The Core project parties would like to congratulate everyone who contributed to the successful go-live of this project.

About the Intraday Capacity Calculation project in the Core CCR
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, the Czech Republic, France, Germany, Hungary, Luxemburg, the Netherlands, Poland, Romania, Slovakia and Slovenia. More information on Core CCR and the explanation of the processes can be found here: https://www.entsoe.eu/bites/ccr-core/about/

Market integration - Core to energy transition
The energy transition towards a carbon free electricity supply is a European challenge that requires the use of the European electricity system to the full extent. Weather-dependent supply and increasing demand response will lead to a different and more intense use of the grid. The Core market integration project is aiming to create operational preconditions to optimise the use of the system from a regional perspective and make the single European market a reality.
