The European Commission Regulation on Capacity Allocation and Congestion Management (CACM) specifies the implementation of Flow-Based Market Coupling (FBMC) for day-ahead electricity trading in the Core Capacity Calculation Region (CCR) comprising Austria, Belgium, Croatia, the Czech Republic, France, Germany, Hungary, Luxembourg, the Netherlands, Poland, Romania, Slovakia and Slovenia. The Core CCR transmission system operators (TSOs) include twelve TSCNET shareholders: 50Hertz, Amprion, APG, ČEPS, ELES, HOPS, MAVIR, PSE, SEPS, TenneT, Transelectrica, and TransnetBW.
The partners of the Core FBMC project are to establish the coupling of all Core CCR borders by means of a Flow-Based Capacity Calculation Methodology (CCM) developed in accordance with the CACM Regulation. The market design for the FBMC implementation has now been finalised and FBMC is currently applied within the Single Day-Ahead Coupling (SDAC) in Central Western Europe (Austria, Belgium, France, Germany, Luxembourg and the Netherlands). The rest of the Core CCR is to follow.
