Successful go-live of the first Core Flow-Based Intraday Capacity Calculation IDCC(d)
The Core project parties are pleased to confirm the successful go-live of the Core Flow Based IDCC(d) process on 28 April 2026.
This milestone marks the next 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 IDCC(d) process delivers capacities by 09:45 for the MTU’s 12:00 – 24:00 of the same business day to Single Intraday Coupling (SIDC) supposed to be used for IDA3 running at 10:00. The results of the IDCC(d) process will be published daily on the JAO Publication tool.
The Core project parties would like to congratulate everyone who contributed to the successful go-live of this project.
Communication channels
Market participants who would like to follow the Core project developments are invited to join the Core Consultative Group (CCG) by signing up to the Core CG distribution list [link]. The participants of the Core Consultative Group will receive regular information and invitations to teleconferences and meetings.
In addition, a Question & Answer Forum is available for the Core Flow-Based capacity calculation project. The Core TSOs encourage all market participants to submit their questions via this Forum, which is accessible through the Core website [link].
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.
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 aims to create operational preconditions to optimize the use of the system from a regional perspective and make the single European market a reality.
