ACER consultation on Core Capacity Calculation methodology

04.12.2018

Complex issues require precise phrasing. Therefore the new public consultation of the Agency for the Cooperation of Energy Regulators (ACER) is called: “Public Consultation on the amendments of the proposal for common capacity calculation methodology for the Core region”. The consultation has opened on 4 December and will be accessible until midnight on Christmas Eve. Invited to participate are all interested stakeholders, including regulatory authorities, nominated electricity market operators (NEMOs) and transmission system operators (TSOs).

What exactly is the objective of the survey? The Capacity Calculation Methodology (CCM) quantifies the electrical capacity that can be offered across borders to the day-ahead and intraday markets. The Core CCM is valid within the Core Capacity Calculation Region (CCR), which comprises Austria, Belgium, Croatia, the Czech Republic, France, Germany, Hungary, Luxembourg, the Netherlands, Poland, Romania, Slovakia and Slovenia. The TSOs from the Core CCR – among them are the twelve TSCNET shareholders 50Hertz, Amprion, APG, ČEPS, ELES, HOPS, MAVIR, PSE, SEPS, TenneT, Transelectrica and TransnetBW – have conceived and proposed amendments to the Core CCM.

The competent regulatory authorities of the Core CCR have not yet approved the TSO proposal and asked ACER to decide on whether the modified Core CCM complies with the European Capacity Allocation and Congestion Management (CACM) Regulation. Interested parties are invited to provide feedback on the consultation questions concerning the relevant aspects of the Core CCM.

Acer decision on fallback procedures for Core CCR

09.10.2018

In March 2018, the Agency for the Cooperation of Energy Regulators (ACER) was asked by the competent regulatory authorities to decide on the amended proposal of the transmission system operators (TSOs) from the Core Capacity Calculation Region (CCR) regarding the Core CCR fallback procedures. In the following August, ACER invited all interested stakeholders to share their views on the issue in a public consultation. After evaluating the survey, ACER has now published its decision on revisions to the methodology for fallback procedures.

The Core CCR consists of sixteen Central European TSOs, twelve of which are TSCNET shareholders: APG (Austria), ČEPS (Czechia), ELES (Slovenia), HOPS (Croatia), MAVIR (Hungary), PSE (Poland), SEPS (Slovakia), Transelectrica (Romania), the Dutch-German TSO TenneT, and the three further TSOs from Germany 50Hertz, Amprion, and TransnetBW. ACER’s decision introduces minimal changes to fallback procedures in order to improve legal clarity and enforceability. Most importantly, instead of five different shadow allocation rules, only a single set of rules is adopted by the Agency, which specifies in its decision to which bidding zone borders these rules apply.

Remarkable ČEPS half-year report

17.09.2018

Jan Kalina, Chairman of the Board of Directors at TSCNET shareholder ČEPS, the Czech transmission system operator (TSO), refers to the essentials of the TSO business by stating: “In the first half of this year, ČEPS fulfilled its mission and ensured secure and reliable national and cross-border power transmission.” Besides that, also the financial figures are most satisfactory with a profit of CZK2.15bn (about €84.4m) before tax and total revenues at CZK 10.36bn (about €407m). This positive performance is accompanied by the company’s improved Moody’s rating of A1.

In 2018, ČEPS continues to implement its extensive investment program based on a ten-year investment plan. In the first half of the year, investments already reached CZK923.1m (about €36.22m). The capex plan actively responds to changes in the energy sector at national and international level. It reflects the potential of the latest trends such as electromobility, renewable energies and battery systems, while maintaining the necessary parameters for a reliable and safe operation of the Czech transmission system.

Among the most important infrastructure projects carried out or to be carried out this year are the comprehensive reconstruction of the substations Čechy Střed (Bohemian Centre) and Otrokovice, as well as the extension and modernisation of the substation Kočín. The gas-insulated section of the Chodov substation is also under reconstruction, which will significantly improve the reliability of power supplies to the Czech capital of Prague.

Phase-shifting transformers stand the test

29.08.2018

In Röhrsdorf in Saxony, Germany, the international conference “Controlling load flows. Strengthening European electricity trading”, organised by the German power transmission system operator (TSO) 50Hertz, a shareholder of TSCNET Services, brought together more than 40 experts to discuss the first experiences with the coordinated use of so-called phase-shifting transformers (PSTs) in Poland, Czechia and Germany. The PSTs put into operation in the past two years allow load flows in the alternating current grid to be better controlled, even between neighbouring countries. In the past, in connection with the German energy transition and electricity trading to southern Europe, there had been an increase in “unplanned loop flows” via Poland and Czechia, some of which had led to a high load on their grids and which practically brought cross-border electricity trade to a standstill.

The coordinated use of PSTs with the Czech TSO ČEPS and the Polish TSO PSE enabled a significant reduction in “unplanned loop flows”, said Dr. Dirk Biermann, Chief Markets & System Operations Officer at 50Hertz. “This is a very pleasing development, because it has relieved the load on the networks of our Polish and Czech neighbours and we can also provide more capacity at the border coupling points for European electricity trading in the future,” explains Biermann. Load flow control with PSTs had very positive effects on the efficient use of the existing power grid. This will be even more important in the future in order to successfully advance the energy transition with an ever increasing share of renewable energies while maintaining a high system stability.

ACER consultation on fallback procedures

02.08.2018

The relevant regulatory authorities have asked the Agency for the Cooperation of Energy Regulators (ACER) to review the fallback procedures in the Core Capacity Calculation Region (CCR) with regard to the European Regulation on Capacity Allocation and Congestion Management (CACM). The Core CCR consists of sixteen central European transmission system operators (TSOs), eleven of which are TSCNET shareholders: APG (Austria), ČEPS (Czechia), ELES (Slovenia), HOPS (Croatia), MAVIR (Hungary), PSE (Poland), SEPS (Slovakia), the Dutch-German TSO TenneT, and the three further TSOs from Germany, 50Hertz, Amprion, and TransnetBW.

The Core TSOs prepared an amended proposal for the CCR fallback procedures. ACER now has been given the task of verifying that this proposal complies with the respective guideline on CACM Regulation of the European Union. Since ACER has to adopt a profound decision on this matter, the Agency takes interest in the comments from different parties on some elements of the amended proposal in order to substantiate this decision. The related public consultation is open til 24 August and all interested stakeholders, including regulatory authorities, nominated electricity market operators and TSOs, are invited to submit their comments.

XBID go live-date confirmed

24.05.2018

Pan-European intraday coupling is crucial for the future European internal energy market. That’s why the Cross-Border Intraday (XBID) initiative was established with the purpose of increasing the overall efficiency of intraday trading. Several Nominated Electricity Market Operators (NEMOs) and nearly twenty transmission system operators (TSOs) from all over the continent collaborate in the XBID initiative, including the TSCNET shareholders 50Hertz, Amprion, APG, TenneT, and TransnetBW, as well as TSCNET client Creos from Luxembourg.

On a technical scale, the XBID Solution is based on a common IT system comprising one shared order book, a capacity management module, and a shipping module. The individual components must be perfectly matched, and in order for all parties participating in XBID to exercise due care, the go-live date for XBID Solution and ten related Local Implementation Projects (LIPs) was postponed earlier this year from March to June.

After a successful completion of additional testing phases as well as two market trial periods, the NEMOs and TSOs now have confirmed the go-live date for XBID. As of 13 June, the ten LIPs will deliver continuous trading of electricity across Austria, Belgium, Denmark, Estonia, Finland, France, Germany, Latvia, Lithuania, Norway, the Netherlands, Portugal, Spain, and Sweden. Most of the other European countries will then follow in a second XBID-wave in summer 2019.

Grid modernisation and profit increase in Czechia

23.04.2018

High revenues from cross-border capacity auctions and system services, sustainable business practices, and well-considered investments in the Czech transmission system belong to the mainstays of a very succesful business year 2017 for TSCNET shareholder ČEPS, the Czech transmission system operator (TSO). The profit of CZK2.897bn (about €114m) before tax represents an increase of CZK824.6m (about €32.5m) in comparison to 2016. As in previous years, ČEPS continued to diligently maintain and expand the national grid in 2017 and spent more than CZK3.5bn (about €138m) on the transmission infrastructure. At the same time, ČEPS transferred a total of 63,372GWh of electricity through the Czech transmission system, which reached a peak load of 11.769MW on 24 January.

The most important milestone in grid modernisation was the installation of four new phase-shifting transformers (PSTs) in the northern Bohemian substation in Hradec u Kadaně, which have been in full operation since September 2017. Jan Kalina, Chairman of the ČEPS Board of Directors, comments on the state-of-the-art PSTs: “These special transformers allow transferring maximum amounts of electricity without threatening the reliability of supplies in the Czech Republic and as such they significantly protect the Czech electricity system against dangerous electricity flows from abroad.” Other major projects completed in 2017 include the reconstruction of the Čechy Střed transformer station in the Central Bohemian Region and the construction of a new 400/110kV transformer station at Vernéřov in the region of Ústí nad Labem.

First edition of the Bidding Zone Review

06.04.2018

With the European Network of Transmission System Operators for Electricity (ENTSO-E) as facilitator, fifteen European transmission system operators (TSOs) have published a first edition of the Bidding Zone Review in line with the European Commission guideline on capacity allocation and congestion management. Among these TSOs are the TSCNET shareholders 50Hertz, Amprion, APG, ČEPS, ELES, Energinet, MAVIR, PSE, TenneT, and TransnetBW as well as the TSCNET customers Creos and SEPS.

The release follows a public consultation of the review, which lasted until 9 March. The involved TSOs have carefully considered stakeholder feedback and have now made their recommendation to the respective national government and regulatory authorities. The competent authorities have to reach an agreement by 30 September on whether to accept the bidding zone configuration or to request modifications.

Start of XBID solution postponed

01.02.2018

Wether technological innovation or business decision – it is always better to take the necessary time and go through conceptions thoroughly, than to compromise ambitious goals with a premature start. This is also the case with the Cross-Border Intraday (XBID) initiative. The original go-live date for XBID Solution and ten Local Implementation Projects (LIPs) has been postponed from March to June 2018, in order to allow for additional testing and two trial trading periods thus ensuring the robustness of XBID.

Nearly twenty transmission system operators (TSOs) from all over Europe are collaborating in the XBID initiative, among them are the TSCNET shareholders 50Hertz, Amprion, APG, Energinet, TenneT, and TransnetBW, as well as TSCNET client Creos from Luxembourg. Along with several Nominated Electricity Market Operators (NEMOs) and under the coordination of the European Network of Transmission System Operators for Electricity (ENTSO-E) the partners are working on a single integrated European intraday market. The basis of this cross-zonal market solution is a common IT system comprising one shared order book, a capacity management module, and a shipping module.

A pan-European coupling of intraday markets through cross-border trade is a key element in creating the European internal electricity market. Provided that the LIP testing phase will be completed successfully, highly efficient intraday trading will be possible across fourteen countries from 12 June. According to the current state of planning, most of the other European countries are to follow in a second XBID-wave in spring or summer 2019.

50Hertz PSTs in regular operation

18.01.2018

The transmission systems of the TSCNET shareholders 50Hertz, one of the four German transmission system operators (TSOs), ČEPS, the Czech TSO, and PSE from Poland are interconnected in the tri-border region of Germany, Poland, and Czechia. To better control the cross-border electricity flows and to increase cross-border capacities, not only close cooperation between these TSOs is an absolute requirement, but also the appropriate technical features. For this reason, all three TSOs started to equip substations near the border with phase-shifting transformers (PSTs) a few years ago.

After a successful three-month trial, 50Hertz put two PSTs at its Röhrsdorf substation in Saxony into regular operation, additionally improving the control of electricity flows between Czechia and Germany. The two 50Hertz PSTs complement their northern Bohemian counterparts in Hradec u Kadaně operated by ČEPS. Further reconstructions in Röhrsdorf are still to follow, before the PSTs can also be switched into the directions of Dresden, Streumen, and Remptendorf. In an expected two years, the PSTs will thus also stabilise the transmission in the southern control area of 50Hertz and make the grid more effective.
