Core projects parties regret to inform market participants that the go live of the Core
Flow Based market coupling (FB MC), currently planned for end of February 2022, will
External dependencies delayed the timely start of the first phase of Core Joint
Integration Testing. In addition, technical issues encountered during the first weeks of
the Joint Integration Testing, require extending the testing phase to ensure robustness
of the systems.
Fixes are being prepared to commence the required re-testing. Project parties are
working hard to minimise the delay. Due to high complexity of the systems and
necessary alignment with external parties, current expectation is that the go live would
take place between beginning of Q2 2022 at the earliest and before the end of Q2
2022 at the latest.
Given these circumstances, Core project parties prepared an updated test planning
and Core FB MC roadmap optimising the testing schedule to reduce the postponement
of go live of Core FB MC as much as possible.
The new go live date highly depends on the further progress of the test planning and
alignment with external parties (e.g. the SDAC) in order to go live with reliable and
robust systems. Core project parties will inform all stakeholders on the new go live
date as soon as this is aligned and confirmed by all involved parties. The Core
Consultative Group will be informed in more detail on the update on 29th November.
Nevetherless, the Core Joint project parties can confirm already that the external
parallel run as performed today will be continued.
About the Day-Ahead Flow-Based Market Coupling project in the Core
The Core Flow-Based Market Coupling (Core FB MC) project promotes the
development and implementation of a flow-based day-ahead market coupling across
the whole Core capacity calculation region (Core CCR) in the framework of the Single
Day-Ahead Coupling (SDAC). 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.
Questions in relation to the Core FB MC project in general and (publication) of the Core
Flow inputs and market coupling simulation results can be raised on the Q&A forum:
Market participants that would like to follow closer the project development are invited
to join the Core Consultative Group (CCG) by sending an email to
CoreCG@magnus.nl. The participants of the Core Consultative Group will receive
regular information, and invitations to teleconferences and meetings.
