[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.
