Paper on MRC extension


The so-called 4M Market Coupling Countries (4M MC) – the Czech Republic, Hungary, Romania and Slovakia – are to be connected to the Europe-wide Multi Regional Coupling (MRC) of the electricity market. This will introduce Single Day-Ahead Coupling across 23 European countries. The initiative to implement the MRC expansion is the DE-AT-PL-4M MC Project, also known as “Interim Coupling Project”. The relevant transmission system operators (TSOs) from Austria, Czechia, Germany, Hungary, Poland, Romania and Slovakia – the TSCNET shareholders 50Hertz, APG, ČEPS, MAVIR, PSE, SEPS, TenneT, and Transelectrica – are part of the project consortium.

The AT-PL-4M MC Project establishes implicit capacity allocation based on Net Transfer Capacity (NTC) at six borders (PL-DE, PL-CZ, PL-SK, CZ-DE, CZ-AT, HU-AT). The Nominated Electricity Market Operators (NEMOs) and TSOs participating in the DE-AT-PL-4M MC Project now have published an information paper for market participants containing key information on the project in a question and answer format. This information includes the main expected changes for the market, the planned communication methods with market participants and a high-level technical description of the market design to be implemented by the project.

Multi Regional Coupling expanded by the end of 2020


The Multi Regional Coupling (MRC) of the European electricity market is to be substantially enhanced by connecting the so-called 4M Market Coupling Countries (4M MC), i.e. the Czech Republic, Hungary, Romania and Slovakia, to the Europe-wide MRC. This will establish Single Day-Ahead Coupling across 23 European countries.

In preparation for this market integration, the so-called Interim Coupling Project (DE-AT-PL-4M MC Project) was launched. It has now completed the design phase and is entering the implementation phase. This provides the Nominated Electricity Market Operators (NEMOs) and transmission system operators (TSOs) from Austria (APG), Germany (50Hertz, Amprion, TenneT, and TransnetBW), Poland (PSE) and the 4M MC countries (ČEPS, MAVIR, Transelectrica and SEPS) with a sound basis for announcing the MRC inclusion for the third quarter of 2020.

The AT-PL-4M MC Project introduces implicit capacity allocation based on Net Transfer Capacity (NTC) at six borders (PL-DE, PL-CZ, PL-SK, CZ-DE, CZ-AT, HU-AT). The competent National Regulatory Authorities (NRAs) welcome the progress made and the synergies from the project, which will facilitate the introduction of Flow-Based Market Coupling in the Core Capacity Calculation Region (Core CCR), which is the ultimate target.

The AT-PL-4M MC project for integrating Czechia, Hungary, Romania and Slovakia into MRC has entered the implementation phase.

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.

ČEPS and SEPS to participate in IPDE


The International Phasor Data Exchange (IPDE) platform is a multinational project to facilitate and optimise the exchange of operational data within the European interconnected transmission system. More specifically, these data derive from time-synchronous voltage, current phasor and frequency measurements which are collected and used in Wide Area Monitoring Systems (WAMS). IPDE is now making significant progress as the two TSCNET shareholder ČEPS and SEPS, the Czech and Slovak transmission system operators (TSO) respectively, have signed an agreement on participating in the platform.

Martin Durčák, Chair of the Board of Directors of ČEPS, comments that the “participation in the platform is another of our continual steps in the introduction of technological innovations and shift towards a digitally managed and controlled grid”. Miroslav Obert, CEO of SEPS, complements: “The project we are undertaking in collaboration with our Czech partners ensures method simplification and uniformity of phasor data exchanges between individual TSOs.”

TSCNET Services welcomes SEPS as shareholder


TSCNET Services is the result of an initiative of European transmission system operators (TSOs), and to this day our company is characterised by a particularly close relationship with our customers, most of whom are also our shareholders. Today we can proudly welcome the Slovak TSO, SEPS (Slovenská elektrizačná prenosová sústava, a. s.), as the new, 14th shareholder. To mark this occasion, we have published a press release on SEPS’ participation as a shareholder.

The Slovak transmission grid consists of 2.138 km of 400 kV lines, 826 km of 220 kV lines and from historical reasons also 80 km of 110 kV lines and is connected with four neighboring countries: Czechia, Poland, Hungary and Ukraine – Burshtyn island. With the exception of the Ukraine, all neighboring TSOs are shareholders and customers of TSCNET. SEPS is solely responsible for electricity transmission throughout the country.

“A quick glance at the map is enough to see that with SEPS’ entry we are now completing the electricity security coordination in the central-eastern part of the continental transmission system” says Uwe Zimmermann, one of the two Managing Directors of TSCNET. “This move will further foster the security of supply in this region and underpins our ambition to further improve the already high quality of our security coordination services.” As a shareholder with full voting rights, SEPS can now also actively contribute to steering and developing the service company.

New interconnectors for Hungary and Slovakia


The Hungarian transmission system operator (TSO) and TSC member MAVIR intends to built two new extra-high voltage lines between Hungary and Slovakia in cooperation with the national Slovak TSO, SEPS. The signing of the related contract took place in the Slovak capital of Bratislava on 1 March. Not only the highest representatives from both TSOs attended the ceremony, but also high profile politcal players, such as Péter Szijjártó, the Hungarian Minister for Foreign Affairs and Trade, or Peter Kažimír and Peter Žiga, Slovak Ministers for Finance and Economy, respectively.

The interconnectors are graded as project of common interest by the European Commission and are part of the European Ten Year Network Development Plan. The first 400kV line will connect the substation Gönyű in Hungary to the hydroelectric power plant Gabčíkovó in Slovakia – both facilities are lying close to the Hungarian-Slovak border. The line will be continued til Velký Ďur in the Slovak region of Nitra. The second line is planned further east, connecting Rimavska Sobotá in the Banská Bystrica Region in Slovakia to Sajóivánka in the Hungarian county of Borsod-Abaúj-Zemplén.

Hungarian Minister Péter Szijjártó acknowledges the cross-border connections as infrastructural key projects contributing to the increase of competitiveness and security supply inh both countries. MAVIR’s Chief Executive Officer, Kamilla Csomai, complements, that the two interconnectors will also facilitate the integration of regional electricity markets. According to the schedule stipulated in the contract, the interconnectors are expected to come into commission by December 2020.

Slovakian neighbourhood connected


One of the biggest benefits for TSCNET’s customers is this: Getting to know what is going on in the neighbouring national transmission grid. The more and the more precise the better. The Slovakian transmission system operator (TSO) SEPS is connected to the neighbouring TSC members ČEPS (Czechia), MAVIR (Hungary), and PSE (Poland), but did not take part in TSCNET’s most important operational forecast processes. Now this has changed. SEPS has “become operational”, as our experts put it: The TSO has been successfully connected to the AMICA system (Advanced Multisite Integral Congestion Assessment) and is now able to participate in most of the processes and services that TSC members use.

SEPS had been participating in the daily operational planning teleconferences (DOPT) via phone since 2013, but didn’t have access to TSC’s IT infrastructure. In April 2016, the negotiations and preparations for a six-month trial membership started. Last week, the Slovakian operators took part in a special training given by TSCNET, and prepared the ground for the technical go-live of the trial-phase. As a Slovak would say: Gratulujeme! Congratulations!
