Development of a single integrated European energy market

Implementation of Regulation (EC) No 714/2009 of the European Union's Third Energy Package

Within the implementation of the two EU regulations CACM (Regulation (EU) 2015/1222) and FCA (Regulation (EU) 2016/1719), 50Hertz, together with the other European transmission network operators, is working intensively on the further development of the coordinated calculation and allocation of cross-border transfer capacities. In particular in the short-term timeframes (day-ahead and intraday) basic objective is the introduction of a flow-based capacity calculation and allocation procedure (Flow Based Market Coupling). In justified cases, it may be deviated in particular regions from this approach.

Objective of EU Regulation CACM is the coordination and harmonization of the capacity calculation as well as the allocation of capacity for the cross-border day-ahead and intraday markets. The Regulation also sets out requirements for the TSOs regarding cooperation at CCR level, at pan-European level and beyond the bidding zone borders.

The capacity calculation should be coordinated at least at regional level in order to ensure a reliable capacity calculation and to ensure that optimum capacity is made available to the market. Therefore, a first step towards within the implementation of EU Regulation CACM is the definition of the regions where such coordination is necessary. According to Article 2 of Regulation (EU) 2015/1222, these regions are defined as "Capacity Calculation Regions (CCR)" meaning "the geographical area in which a coordinated capacity calculation is applied". The CCRs have been defined on 17.11.2016 by the Agency for the Cooperation of Energy Regulatory Authorities (ACER) and published under the following link:


Further methods resulting from the implementation of the two EU regulations CACM and FCA that are to be published pursuant to Article 9 (14) CACM respectively Article 4 (13) FCA can be found on the information platform of the four German TSOs under the heading "EU Network Codes" respectively on the websites of the European network of transmission system operators for electricity (ENTSO-E) to the respective EU regulation CACM and FCA

Day-Ahead Market Coupling

To achieve the European Commission's goal of creating a pan-European electricity market, the European Commission has introduced the Integrated Single Price Coupling (SPC) across Europe for day-ahead power trading.

Intraday Market Coupling

In order to create an integrated European electricity market, power exchanges and transmission system operators from twelve countries have launched an initiative called “XBID Market Project”. The purpose of the XBID Market Project is to enable continuous cross-border trade and to increase the efficiency of intraday trading in general through a single cross-border intraday market in Europe.
