Region: Core FB MC project

02.Dec 2020.

The progressive transition towards the external parallel run, which provides the publication of the first flow-based capacity calculation data and of related simulated market coupling results was announced by the project parties involved in the day-ahead Core Flow-Based Market Coupling project (Core FB MC).

The publication of these simulated results will allow market participants to get acquainted with the Core flow-based day-ahead results and to start their preparations towards the Core FB MC go-live.

The project parties will initially publish only selected days (between 0 and 7 per week), whenever the results are deemed sufficiently representative. Core project parties will focus in the coming months on the stabilization of the tooling and will announce when the reliable publication of 7 business days per week can be initiated.

Core project parties underline that NRAO (non-costly remedial action optimizer) will unfortunately not be available at the beginning. It means that for some TSOs relying on non-costly remedial actions (especially RTE), there is a clear limitation and results might be different when NRAO would be available. Core TSOs are working proactively in order to deliver this tool and will keep market parties informed on the progress.

The first capacity calculation data can be expected on the JAO website latest on 6 December; the related market coupling simulated results will be published on 13 December, covering the sufficiently representative business days of week 47 (16 – 22 November 2020).

The Core FB MC go-live date has been recently updated to February 2022 taking into account the guidance of European Commission and Core NRAs that Interim Coupling Project (ICP) should be implemented as an interim step to the Core FB MC.

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.
