High-Level Market Design finalised


It was only at the end of 2018 that the national regulatory authorities of Austria, Germany, Poland and the so-called 4MMC countries (Czechia, Hungary, Romania, and Slovakia) requested the initiation of the interim project for an NTC-based market coupling (“Net Transfer Capacities”) between these countries. The parties involved in the DE-AT-PL-4MMC (“Interim Coupling”) project have completed the High-Level Market Design to be implemented and the national regulatory authorities have confirmed their support for the continuation of the project. This involves a total of eight TSOs that are shareholders and customers of TSCNET Services: 50Hertz (Germany), APG (Austria), ČEPS (Czechia), MAVIR (Hungary), PSE (Poland), SEPS (Slovakia), TenneT (Germany), and Transelectrica (Romania).

The project aims to couple 4MMC and Poland as well as Multi-Regional Coupling (MRC) through the introduction of NTC-based implicit allocation on six borders (PL-DE, PL-CZ, PL-SK, CZ-DE, CZ-AT, HU-AT) and the implementation of a Single Day Ahead Coupling (SDAC). The project envisages a step-by-step transition at the above-mentioned boundaries from the current NTC-based explicit allocation to the flow-based implicit allocation to be implemented in the framework of the CoreFlow-Based Market Coupling Projectas target solution required by regulation. The Interim Coupling significantly contributes to the regional market integration and brings benefits to the market. The current planning envisages the go-live of the interim coupling for the second quarter of 2020.

PSE presents diagnosis of energy market


As a European transmission system operator (TSO), the Polish TSCNET shareholder PSE is well aware of its responsibility for the continental electricity market in its entirety and for transnational supply and system security. That is whay PSE is thoroughly monitoring market developments and how regulatory specifications affect them. The company identifies several main challenges that force the European TSOs to reconsider the fundamentals of the European energy market, first of all the increase of decentralised generation due to the growing role of the renewables or consumer production.

Eryk Kłossowski, President of the PSE Management Board, clearly expresses PSE’s attitude to the current setting of the course, and especially the debate on market design: “It is the most important dispute concerning the electricity industry”. In order to assume an important role within this discussion, PSE publishes from now on a series of position papers concerning the European electricity market. The first of these, “The European Electricity Market ‒ diagnosis”, soundly deals with such important aspects as the sizing of bidding zones and cross-zonal exchange.


The Polish transmission system operator PSE has published a position paper on the European energy market design.

TSC member Swissgrid, the Swiss transmission system operator (TSO), recently presented proposals concerning a new market design for Swissgrid to numerous industry representatives. The company was lucky to receive a rich feedback. On 24 June 2016, Swissgrid released a document summarising the responses and assessments, also highlighting Swissgrid’s primary tasks for the near future. The main actions featured in the document are intended to increase the efficiency of the eletricity market. Swissgrid will develop concepts for:

  • A real-time-based balance energy price in order to compensate generators and consumers adequately
  • Cross-border intraday auctions to improve the distribution of capacities
  • Further clarification of respective responsibilities concerning supply security, especially in the course of the industry working group “Responsibility for Electricity Security of Supply”.

Swissgrid proposals taken into debate


In mid-December 2015, TSC member Swissgrid had introduced suggestions for a new market design to raise the efficiency of the electricity market. Following a workshop and various discussions with industry representatives, the Swiss transmission system operator (TSO) received valuable feedback. The proposed reforms to strengthen the price signal and the suggested improvements of cross-border trade met with a largely positive response. Swissgrid’s proposals concerning a market-based, regional approach to secure supply were discussed more controversially. Swissgrid is going to resume the feedback and findings in a final document.
