The launch of the Core Flow-Based Market Coupling is targeted for 20 April 2022 (trading for delivery on 21 April). It will mark the transition to a single coupled auction for the day-ahead market across the Core region, based on the flow-based capacity calculation methodology. This allows for a regional optimization of the capacity allocation in the day ahead timeframe. Currently the project is in the Joint Integration Testing phase. The formal go-live decision will be taken in advance of the planned go-live date.
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.
