Latest market news
In December 2020, the TSOs Statnett and TenneT will start the commercial operation of NordLink, the new interconnector between Norway and Germany. The exact date will be published in a later message as this depends on the successful completion of the transmission test phase. According to current plan, market operation will start 1st December.
The NordLink capacity, that will be given to the day ahead and intraday market coupling, is the outcome of TenneT´s and Statnett´s capacity calculation process. On the German side, this includes the obligation of the German Action Plan to offer a minimum percentage of capacity per critical network element for cross-border trades.
The table below shows the linear trajectory of these minimum percentages to be applied on the critical network elements for NordLink from start of commercial operation in 2020 until 70% are reached by 31.12.2025:
|year||% of capacity per critical network element|
|from 31.12.2025 onwards||70|
Under coordination of Bundesnetzagentur the system operators Baltic Cable AB, Schleswig-Holstein Netz AG and TenneT TSO GmbH jointly developed an interim solution for the Baltic Cable (constituting the bidding zone border DE/LU – SE4) to meet the minimum transmission capacity according to the German Action Plan in line with article 15 of EU regulation 943/2019 (of 248 MW during the year 2020). The interim solution provides the possibility to apply costly remedial actions in order to avoid the day-ahead transmission capacity of BC to fall below the required minimum capacity.
Once TenneT and Energinet have successfully commissioned the new common 400kV-connection as replacement of the existing common 220kV-connection between substation Kassö (DK1) and substation Handewitt – replacement of substation Flensburg – (DE/LU) within the frame of the so called East Coast Project (“Mittelachse”), TenneT’s Guaranteed Hourly NTC will change according to TenneT’s Commitment towards DG Competition as follows.
Under the principle of a linear trajectory, the TenneT Guaranteed Hourly NTC shall be increased by equal yearly steps corresponding to the overall increase of the East Coast Line (575 MW) (“Mittelachse”) divided by the number of calendar years between (i) 1 January following the commissioning of the East Coast Line (“Mittelachse”) and (ii) 1 January 2026 resulting in annual increases of 96 MW. Thus, TenneT’s Guaranteed Hourly NTC increases from currently 1,300 MW to 1,396 MW by 1 January 2021.
Note that the maximum NTC was changed from 1,500 MW in southbound direction and 1,780 MW in northbound direction to 2,500 MW of either direction with the date of commissioning the new common 400kV-connection.
Further note that the applicable NTC to determine the offered capacity is the hourly minimum of TenneT’s and Energinet’s individual hourly NTCs. TenneT’s hourly NTC is still subject to daily capacity calculation that could result in any value between TenneT’s Guaranteed Hourly NTC and the maximum NTC being in accordance with the requirements from the German Action Plan according to article 15 of regulation (EU) 943/2019. Energinet’s NTC is in the sole responsibility of Energinet and not affected by TenneT’s Guaranteed Hourly NTC or the German Action Plan.
TenneT’s Guaranteed Hourly NTC will further increase with the future commissioning of the West Coast Line by means of a linear trajectory of additional 750 MW.
Announcement: Successful go-live of daily D-2 auctions for FCR
On June 27, the FCR cooperation, which consists of 50Hertz, Amprion, APG, Elia, Energinet (non-active member), RTE, Swissgrid, TransnetBW, TenneT Germany and TenneT Netherlands, took a first step towards the implementation of a new FCR market design to procure nearly half of the FCR capacity in the synchronous area. In addition to shortening the product length from one week to one day, the cooperation introduces a marginal pricing system. Within this framework, a complex allocation algorithm was developed on the basis of an optimization based on constraints, which takes different price zones into account.
The goal of the further development is a reduction of procurement costs as well as the creation of entry incentives for new standard service providers and technologies.
The FCR cooperation is the first regional cooperation to implement market harmonization using the method prescribed by the Guideline on Electricity Balancing (EBGL). The development path was developed with the involvement of stakeholders and regional cooperation regulators.
During the last two years, two consultation rounds have been carried out, during which detailed proposals have been developed and reports evaluated. The development resulted in a final proposal according to Art. 33 of the EBGL, which was approved by all participating national regulators.
In the course of the further procedure, product time slices of four hours are expected to be introduced in July 2020. In addition, the time of the market close is to be brought closer to the delivery period.
This consultation is based on Article 6 of Commission Regulation (EU) 2016/1719 (FCA Regulation) and concerns the review of Harmonised Allocation Rules in accordance with Article 68(5) of these rules. Together with the Harmonised Allocation Rules main body all annexes which propose amendments will be consulted.

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.
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.
More information in the press release
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:
Capacity according to Joint Declaration
New minimum available hourly capacity according to Commitment
[1.300 – 2.625 MW]*
*Capacity depends on the commissioning of planned interconnectors East Coast Line and West Coast Line.
