[Core] Confirmation of Core Flow-Based Intraday Capacity Calculation (c) go-live for business day 25 June 2025

Confirmation of Core Flow-Based Intraday Capacity Calculation (c) go-

live for business day 25 June 2025

Date: 27-05-2024

Core project parties are pleased to confirm 25 June 2025 as the go-live date of IDCC(c) for

trades on business day 25 June 2025. The external parallel run has demonstrated the stability

of the process. Core project parties deem the results representative, thus no significant

impact is expected from the remaining deployment of individual validation tools. Core

project parties will continue to closely monitor the remaining period until go-live.

 

Final operational communication on the go-live preparation of IDCC(c) and its completion

can be expected on 24 June 2025 respectively 25 June 2025.

 

The IDCC(c) process delivers updated cross-zonal capacities by 4:30 to the Single Intraday

Coupling (SIDC) market platform for MTU’s 6:00 – 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 next step in the implementation of the sequence of flow-based intraday

capacity calculation in the region and a big step towards the optimisation of the available

capacity for the intraday market while respecting operational security using the latest

available CGM (common grid model).

 

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.

 

Next to the Core CG, a Question & Answer Forum for the Core FB capacity calculation project

is currently in use. The Forum can be accessed via https://coreforum.my-ems.net/.

The Core TSOs invite all market participants to use this Forum for their queries.

 

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,

Ireland, North–Ireland, 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 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.
