The project parties involved in the day-ahead Core Flow-Based Market Coupling project (Core FB MC) communicated on 19 November 2021 the delay of Core FB MC, due to external dependencies delaying a timely start of the first phase of Core Joint Integration Testing and technical issues encountered during the first weeks of testing. The new go live date was depending on the further progress of the test planning and alignment with external parties (e.g. the SDAC). Core project parties would like to share the progress made.

The first phase of joint regional testing (Full Integration Testing - FIT) finished successfully on 13 January 2022. The FIT testing, focused on functionality between all systems involved in the FB MC process, has proven that the given solution is able to perform the FB MC process.

The next phase of the testing (Simulation Integration Testing – SIT) has started on 17th January 2022 and is expected to run until the end of February 2022. The SIT testing is focused on testing of the joint operational procedures to prove, that the solution is capable of facilitating the daily operational process.

After the test performed in the course of January and the alignment with external parties (SDAC), the project parties can now confirm that the new go-live date will be 20th April 2022 (trading day for delivery on 21st April 2022).

Core project parties will keep informing market participants about following steps in the project that are relevant for a robust and reliable go-live and planned activities.

Communication channels
Market participants who would like to follow closer the project development are invited to join the Core Consultative Group (CCG) by sending an email to The participants of the Core Consultative Group will receive regular information, and invitations to teleconferences and meetings.
Next to the CCG a Question & Answer Forum for the Core FB MC project is currently in use. The Forum is available under the Core FB MC section on the JAO website, ie. Project parties invite all market participants to use this Forum for their queries.

About the Day-Ahead Flow-Based Market Coupling project in the Core CCR
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.

Market integration is core to the 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 extend. 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.
