Single Intraday Coupling expanded

08.11.2019

Europe-wide intraday coupling is a key component for the completion of the European internal energy market. To help achieve this goal, the European cross-border Single Intraday Coupling (SIDC) solution was launched in June 2018 (then called XBID), standing for a significant step towards a single integrated continent-wide intraday market. A market of this kind increases the overall efficiency of intraday trading through effective competition, increased liquidity and more efficient use of generation resources across Europe. The SIDC solution is based on a common IT system with a common order book, a capacity management module and a shipping module.

The participating countries were initially Austria, Belgium, Denmark, Estonia, Finland, France, Germany, Latvia, Lithuania, Norway, the Netherlands, Portugal, Spain and Sweden. SDIC will now be expanded and continuous electricity trading will be possible across seven further countries: Bulgaria, Croatia, the Czech Republic, Hungary, Poland, Romania and Slovenia. Nominated electricity market operators (NEMOs) and the participating transmission system operators (TSOs) have confirmed the go-live of the extended SIDC and two additional local implementation projects on 19 November with first deliveries on 20 November.

TSOs already collaborating in SIDC include the TSCNET shareholders 50Hertz, Amprion, APG, TenneT, TransnetBW and Energinet as well as the TSCNET client Creos from Luxembourg. With the second wave, six more shareholders follow, namely ČEPS, ELES, HOPS, MAVIR, PSE and Transelectrica.

Key ENTSO-E report on regional coordination

07.11.2019

At national level, the main tasks of transmission system operators (TSOs) are the transport of electricity from producers to large consumers and distribution networks, ensuring the operational safety as well as the planning, development and modernisation of electricity grids to ensure security of supply and cost-efficiency. More recently, TSOs have also been held responsible for achieving climate and energy policy objectives. European TSOs have also long been thinking and acting across borders in an increasingly integrated energy market. To ensure safe operation at European level, national TSOs coordinate at regional and pan-European level.

The European Network of Transmission System Operators for Electricity (ENTSO-E) now has published the “Enhanced TSO Regional Coordination for Europe” report, coming with the suggestive subtitle: “Act locally, coordinate regionally, think European”. This report with a time perspective until 2030 describes the shift of the five European Regional Security Coordinators (RSCs) such as TSCNET Services to Regional Coordination Centres (RCCs) in the wake of the Clean Energy Package (CEP). It focuses on operational and market needs, without disregarding the fact that regional cooperation between TSOs goes beyond these two issues. Nevertheless, the emphasis was put on these aspects, as markets and operations are more and more converging: Electricity is traded closer to real time, markets are more volatile, generation is more variable and cross-border and long-distance transmission are increasing. For this reason, the interfaces between market and physical infrastructure require to be consolidated.

The “Enhanced TSO Regional Coordination for Europe” report contains several recommendations and a roadmap for the coordination of TSOs to continue on the path towards a future European energy system that is sustainable, socially balanced and reliable. The five standard operational services of the RSCs – Common Grid Model, Coordinated Operational Planning, Security Analysis, Outage Planning Coordination, Short- to Medium-Term Adequacy Forecast, and Coordinated Capacity Calculation – and the Service for Organisational Support – Consistency Check of TSOs’ System Defence and Restoration Plans – are to be ported from RSCs to RCCs over the next decade.

New Nordic System Operation Agreement

04.10.2019

The five Nordic power transmission system operator (TSOs), including the Danish TSCNET shareholder Energinet, have signed a new Nordic System Operation Agreement. This agreement sets out the common operating principles of the Nordic TSOs to ensure that the Nordic interconnected system is operated reliably and efficiently in accordance with national and European regulations.

Against the background of the increasing volatility of electricity generation due to renewable energies and the reduction of balancing power generation, the Operating Agreement will further strengthen Nordic cooperation, harmonise grid operating practices between Nordic countries and within Europe, and ensure the system security of the Nordic electricity system.

The document will also contain several appendices, of which the appendix on reserves has already been concluded. The Nordic TSOs are in the process of finalising further appendices on all relevant operational issues. The new Operation Agreement will successively replace the existing one after the completion of the new appendices.

ENTSO-E reports on implementation of market network codes

04.09.2019

The EU network codes are a concise set of rules to promote the harmonisation of national electricity markets and regulations on the way to the European Energy Union. A fully functioning and interconnected internal energy market will strengthen Europe’s competitiveness, contribute to the integration of more renewable energies and ensure security of supply.

The network codes are divided into three families: connection, operation and market. The guidelines for Capacity Allocation and Congestion Management (CACM) and for Forward Capacity Allocation (FCA) are an integral part of the market code family. The progress made by the European transmission system operators (TSOs) in implementing these regulations is documented in two reports which have now been published by the European Network of Transmission System Operators for Electricity (ENTSO-E).

The “ENTSO-E Market Report 2019” outlines the progress in day-ahead and intraday coupling as well as in FCA, and the “ENTSO-E Report on Capacity Calculation and Allocation 2019” covers the capacity calculation in the ten capacity calculation regions (CCRs). The latter report also assesses capacity calculation and allocation based on statistical and quality indicators.

COBRAcable market launch on 7 September

02.09.2019

After three years of construction, including the laying of the submarine cables as well as the construction of two onshore converter stations, and a successful test phase earlier this year, COBRAcable will be available for the electricity market as of the delivery day of 7 September, which is exactly on schedule. The first direct connection between the electricity markets of Denmark and the Netherlands was jointly realised and is operated by the two TSCNET shareholders Energinet, the Danish transmission system operator (TSO), and TenneT, the Dutch-German TSO.

The high-voltage DC cable with a length of about 325km has a capacity of 700MW. The Netherlands can import more sustainable electricity from Denmark through COBRAcable, mainly wind energy. In addition, the cable provides Dutch capacity on a structural basis for the Danish electricity grid, thus ensuring security of supply in Denmark, which of course also works the other way round. Moreover, the cable connection is designed in such a way that an offshore wind farm can be connected at a later date, so that COBRAcable contributes to a sustainable European energy landscape.

Regional Coordination Centre for South-East Europe

18.07.2019

The three transmission system operators (TSOs) of the South-East Europe Capacity Calculation Region (CCR) – TSCNET shareholder Transelectrica from Romania, ESO from Bulgaria and IPTO from Greece – have signed a memorandum of understanding (MoU) on establishing a Regional Coordination Centre (RCC). The memorandum emphasises the ambition of the TSOs to strengthen regional cooperation and thus contribute to the safety and efficiency of the European transmission system.

The agreement provides a cooperation framework between the three contracting parties with the common objective of finding a mutually acceptable solution for the implementation of an RCC on the principle of meeting the requirements of the Third European Energy Package and the Clean Energy for all Europeans Package as efficiently, effectively and timely as possible. The MoU sets a time frame for the core decisions. The SEE capacity calculator is to be determined as early as 4 August 2019 and the necessary documents for the founding of the RCC are to be signed by the end of the year.

Imminent test operation for COBRAcable

24.06.2019

COBRAcable, the first direct interconnection between the electricity markets of Denmark and the Netherlands, is a joint project of the two TSCNET shareholders Energinet, the Danish transmission system operator (TSO), and TenneT, the Dutch-German TSO. Since spring, the partner TSOs have been preparing the commercial operation of COBRAcable. TenneT and Energinet have now launched an Urgent Market Messages (UMM) site for the commissioning of COBRAcable, which is scheduled to take place between 3 July 2019 and 6 September 2019.

A total of around 30 individual tests with different energy charges in the respective transport directions are planned. It is expected that the full capacity of COBRAcable will be available for the day ahead and intraday markets from 7 September. TenneT and Energinet then will offer financial transmission rights on COBRAcable at monthly and annual auctions. The first auction is expected to take place after a full month of stable operation, so probably the auction for November 2019, which will be held in October.

By promoting the exchange of surplus wind energy, COBRAcable will improve the cohesion of the European transmission system and the integration of the electricity market. It will also make a sustainable contribution to the low carbon energy future by allowing future offshore wind farms in the North Sea to be hooked up to the DC interconnector.

Energinet and Tennet will carry out individual tests of COBRAcable as of 3 July (picture: screenshot taken from TenneT video “COBRAcable Cable Pull Fano Denmark Film”, YouTube)

Second go-live wave of XBID

13.06.2019

The successful go-live of XBID, the European cross-border Single Intraday Coupling (SIDC) solution, on 12/13 June 2018 was a significant step towards a single integrated continent-wide intraday market. Such an integrated market increases the overall efficiency of intraday trade through effective competition, increased liquidity and more efficient utilisation of generation resources across Europe. Today the first anniversary of XBID is celebrated and over 16 million trades have been executed since its launch.

The SIDC partners look back on a successful first year of operation with a stable and robust system performance as well as a high and growing number of trades across Austria, Belgium, Denmark, Estonia, Finland, France, Germany, Latvia, Lithuania, Norway, the Netherlands, Portugal, Spain, and Sweden. The integration of seven additional countries into the SIDC region is expected in the fourth quarter of 2019. A pre-launch event for the second wave is planned for the beginning of October 2019 and a trial period will also be arranged with the market parties. The countries for this second go-live wave are Bulgaria, Croatia, the Czech Republic, Hungary, Poland, Romania, and Slovenia.

The TSOs already cooperating in XBID include the TSCNET shareholders 50Hertz, Amprion, APG, TenneT, and TransnetBW as well as the TSCNET client Creos from Luxembourg. Further shareholders are to follow with the second wave, namely ČEPS, ELES, HOPS, MAVIR, PSE, and Transelectrica.

Agreement on synchronous interconnection

01.06.2019

There are five synchronous electricity areas in Europe: Continental Europe (CE), Nordic, Baltic, British and finally the area of Ireland and Northern Ireland. The CE area with the synchronised transmission grids of 26 countries is not only the largest in Europe, but also one of the largest interconnected power systems worldwide. The synchronisation of the Baltic area with CE is of strategic importance for the European Energy Union, one of the political priorities of the European Commission. Currently, the Baltic system is only asynchronously linked to CE between Lithuania and Poland through the “LitPol Link” and at two points to the Nordic region.

An application for a future synchronisation of the Baltic and CE systems was made by the three Baltic transmission system operators (TSOs) Elering, AST and Litgrid with support from TSCNET shareholder PSE, the Polish TSO. The European Network of Transmission System Operators (ENTSO-E) has now announced the first landmark for the project: An agreement on the conditions for a synchronous interconnection became effective on 27 May 2019. Synchronisation will enable the Baltic TSOs to operate their systems in the future at the same frequency as the CE system and in compliance with EU rules.

EU Parliament approves “Clean Energy Package”

27.03.2019

On 26 March 2019, the Members of the European Parliament adopted four new laws on the EU electricity market, which were agreed informally with EU ministers at the end of 2018. In detail, these are the new Electricity Market Regulation and Electricity Market Directive as well as the Regulations on Risk Preparedness and the Agency for the Cooperation of Energy Regulators (ACER). This concludes the “Clean Energy for All Europeans Package” (CEP). The agreements now need to be formally approved by the EU ministers and published in the EU Official Journal before they can enter into force.

The overall objective of the CEP is to create a Europe-wide market for electricity that is cleaner, more competitive and more risk-adjusted. One of the more specific targets is to freely distribute at least 70% of trading capacity across borders from 2020 on in order to facilitate trade in renewable energy across EU borders and thus support the efforts to meet the EU’s binding target of 32% renewable energy by 2030 and to fulfil the obligations of the Paris Agreement. The regulation on ACER implies that the Agency will be given more tasks and powers.
