Core FB MC Market Design is finalised for implementation - Flow-Based Market Coupling to be implemented in the Core Capacity Calculation Region

Vienna, Brussel, Zagreb, Prague, Paris, Berlin, Budapest, Luxemburg, Amsterdam, Warsaw, Bucharest, Bratislava, Ljubljana, 17 April 2019

According to article 20 of the Commission Regulation (EU) 2015/1222 establishing a guideline on capacity allocation and congestion management (CACM Regulation), a Flow-Based market coupling for the day-ahead timeframe has to be implemented in the Core capacity calculation region (Core CCR). The project parties involved in the Core Flow-Based Market Coupling project have finalised the Market Design for Implementation. The current planning foresees the go-live of Flow-Based Market Coupling in the Core CCR in Q4 2020.

Flow-Based Market Coupling is currently deployed within the Single Day-Ahead Coupling across Central Western Europe (CWE) covering Austria, Belgium, France, Germany, Luxemburg and the Netherlands.

With the Core Flow-Based Market Coupling project, all borders of the Core CCR will be coupled based on a Flow-Based capacity calculation methodology developed in the framework of the CACM Regulation.

About the Flow-Based Market Coupling project in Core

The Core Flow-Based Market Coupling 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.

CCR Hansa TSOs’ announcement on the release of ID capacities

The CCR Hansa TSOs decided to offer left over capacities to the extent possible at 18:00 (with no guarantee that full leftover DA capacities will be provided to the ID market). In the following paper, the CCR Hansa TSOs outline the reasoning for the release of intraday capacities at 18:00.

Minimum available hourly capacities for DE-DK West according to Joint Declaration and TenneT’s Commitment

According  to the Joint Declaration from the Danish Ministry of Energy, Utility and Climate and the German Economic Ministry in June 2017 on increasing the electricity trade between the two countries (see press release http://www.bmwi.de/Redaktion/DE/Pressemitteilungen/2017/20170614-deutschland-und-daenemark-einigung-auf-stromhandel.html and https://en.efkm.dk/news/news-archive/2017/jun/denmark-and-germany-agree-on-increasing-electricity-trade-between-their-countries/) and TenneT’s commitment towards the European Commission (see press release: https://www.tennet.eu/de/news/news/tennet-begruesst-entscheidung-der-eu-kommission-fuer-stromhandel-an-deutsch-daenischer-grenze/), the relevant Transmission System Operators of both countries, TenneT and Energinet, have agreed on the implementation of a joint countertrading program.

While Energinet and TenneT already met the requirements from the Joint Declaration since July 2017 for guaranteeing minimum available hourly capacities for both directions of the border DE/DK-West, TenneT needs to implement the additional demands from the commitment. Therefore, both Transmission System Operators have signed an extended agreement to support TenneT in meeting its commitments.

The minimum available hourly capacities are derived from both obligations. With respect to safeguarding system stability exceptions have been defined for reducing capacity guarantees. The minimum capacity applies for both trading directions in the day-ahead allocation. The table below shows the minimum available hourly capacities for the next periods:
