Communication note

25 November 2021: Postponement of the Core Flow-Based Market Coupling project Go-Live date of end of February 2022

SDAC 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 be postponed.

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. Core 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 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
