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.

ENTSO-E report on frequency drop

29.05.2019

On Thursday, 10 January 2019, shortly after 9 p.m., a deviation from the 50Hz mid-frequency was registered in the Continental European (CE) power system, which comprises the synchronised transmission grids of 26 countries. The deviation lasted 9 seconds and, with a drop to 49.808Hz, was the largest absolute frequency deviation since the so-called “European Blackout 2006”, when the frequency reached 49.0Hz.

Thanks to immediate collective action by the transmission system operators (TSOs) of the CE Regional Group the underfrequency was quickly rectified and the European security of supply was not compromised at any moment. In concrete terms, the activation of CE reserves and of interruptible contracts with French industrial customers returned the situation to normal. To identify the root causes of the incident, the European Network of Transmission System Operators for Electricity (ENTSO-E) undertook in-depth investigations and has now released a detailed and transparent technical analysis.

According to this report, the large drop was caused by the superposition of two factors. A significant deterministic frequency deviation (DFD) during the evening peak load encountered another, unpredicted one, registered between 9 and 11 January and caused by a technical error resulting from a frozen measurement on four connecting lines between Austria and Germany. The cumulative effect of the permanent frequency deviation from 9 to 11 January and the significant evening DFD on 10 January led to the frequency loss in the interconnected CE system.

The ENTSO-E technical report indicates that solutions for DFDs in the CE region need to be found. DFDs have been observed for years, but are now becoming more common and are of greater amplitude due to imbalances between generation and demand. Possible solutions to DFDs may require a change in operating and/or market rules. ENTSO-E will make further enquiries in close dialogue with all interested parties.

Strong improvements in NDPs of TSOs

28.05.2019

The individual Network Development Plans (NDPs) of the European transmission system operators (TSOs) set the parameters for the development of the electrical transmission infrastructure on the national scale. At the pan-European level, the biennial Ten-Year Network Development Plans (TYNDPs) – conceived by the European Network of Transmission System Operators for Electricity (ENTSO-E) with the participation of the member TSOs – provide the framework for in-depth identification of continent-wide key investments and infrastructure projects with high potential. It is the task of the Agency for the Cooperation of Energy Regulators (ACER) to assess the coherence of national and EU-wide NDPs.

ACER now has published its detailed opinion on the schemes, scenarios and projects included in the most recent national NDPs. ACER is pleased to find that the coherence with the European TYNDP has substantially improved, e.g. through a wider use of cost-benefit analysis for projects or a more systematic use of a multi-scenario approach. In its 84-page opinion, however, the Agency also calls for some improvements to reduce inconsistencies.

Retrospect on Innogrid2020+

15.05.2019

This year’s Innogrid2020+ took place in Brussels on 13 and 14 May. Jointly organised by the European Network of Transmission System Operators for Electricity (ENTSO-E) and the European Distribution System Operators for Smart Grids (EDSO), the motto of the prestigious annual event for 2019 was “Connecting Physics and Digits: Power Platforms on the Rise”. So, it was about physical networks and their permeation with information and communication technologies, transforming the energy system into a cyberphysical system. Among the presented projects during Innogrid2020+ were several, in which TSCNET shareholders participate: “Crossbow” with Croatian transmission system operator (TSO) HOPS, “DA/RE” by German TSO TransnetBW, “FutureFlow” (ELES from Slovenia, APG from Austria, MAVIR from Hungary, and Transelectrica from Romania), “MIGRATE” (Amprion from Germany, ELES, and Dutch-German TSO TenneT), and SINCRO.GRID (ELES and HOPS). Besides, Yves Zumwald, CEO of Swissgrid, took part as speaker in the “CEO business track panel on innovation”.

In addition to informative sessions on disruptive technologies, innovation policy or targets for 2030, the event hosts also presented the 2nd European Power Network Awards during Innogrid2020+. The first winner is the Signposting Information project by the British Distribution System Operator (DSO) WPG, which aims to open new neutral markets around flexibility. The second winner is the digital platform “cyberNOC” by CyberGRID, a specialist in the development of virtual power plant solutions. cyberNOC stands for the seamless and secure integration of battery energy storage systems and electric vehicles with aggregators, electricity markets, and grid operators.

On the second day of Innogrid2020+, ENTSO-E and EDSO used the public interest in the event to present six recommendations on energy network innovation to the European Commission in the forefront of the Copenhagen Energy Infrastructure Forum on 23 and 24 May. These recommendations include the promotion of TSO-DSO cooperation, adequate support for research, development and innovation, of sectoral coupling and digitisation, or the linking of EU funding programmes.

News from PCI Energy Days

20.03.2019

The PCI Energy Days, organised by the European Commission (EC), offer promoters of European Projects of Common Interest (PCIs) the opportunity to present their projects and exchange experiences on how to build a future-proof and environmentally friendly energy infrastructure with innovative concepts. The inaugural PCI Energy Days took place on 19 and 20 March 2019 in the Belgian capital of Brussels and featured a policy conference as well as an exhibition on the practical implementation of specific PCIs. Among the attendees were the European Network of Transmission System Operators for Electricity (ENTSOE), the three transmission system operators (TSO) and TSCNET shareholders ELES from Slovenia, HOPS from Croatia and the Dutch-German company TenneT.

ELES took the opportunity to present in cooperation with HOPS the Croatian-Slovenian smart grid project SINCRO.GRID. Coordinated by ELES, SINCRO.GRID comprises in addition to the TSOs also two distribution system operators (DSOs) from both countries. The aim of the cross-border project is to optimise the efficiency of the respective national power transmission systems using advanced technologies and innovative data processing methods.

The Renewables Grid Initiative (RGI), an association of non-governmental organisations (NGOs) and TSOs from all over Europe, was also present at the PCI Energy Days to celebrate the signing of the Marine Grid Declaration. The Declaration sets out principles for grid development in the marine environment, such as promoting early mutual communication with stakeholders, adequate protection of the marine environment and knowledge sharing. The RGI members, which include the TSCNET shareholders 50Hertz, Amprion, HOPS, Swissgrid and TenneT, recognise the cooperation between TSO and NGOs as a highly promising approach to building a sustainable marine grid infrastructure. The signatories to the Declaration commit themselves to developing marine projects in accordance with nature conservation principles and early stakeholder involvement. The Marine Grid Declaration builds on the principles previously agreed in RGI’s European Grid Declaration. If you are interested, you can still sign both declarations. In this case, please contact the RGI.

New syllabus for network codes

12.03.2019

The EU electricity network codes and guidelines are a detailed set of rules to promote the harmonisation of national electricity markets and regulations on the way to the European Energy Union. By the end of 2017, a total of eight network codes and guidelines have been implemented: three grid connection codes, three market codes and two operation codes. In order to raise awareness of these innovative pan-European rules for a more sustainable, reliable and interconnected power system and to better involve market participants in the code contents and their implementation, the Florence School of Regulation (FSR) has published a new syllabus as part of its online training on European network codes.

The online course partners of the FSR are those institutions that have developed the codes: the European Network of Transmission System Operators for Electricity (ENTSO-E), the European Agency for Cooperation of Energy Regulators (ACER) and the European Commission. The new manual deals mainly with market codes and discusses, for instance, the different European electricity markets and their establishment in the national context as well as their integration. Also, two connection codes are described and their technical requirements clarified. The syllabus is also a beneficial addition to ENTSO-E’s e-codes application for smartphones.

TSOs release data under open license

03.02.2019

The European power transmission system operators (TSOs), represented by the European Network of Transmission System Operators for Electricity (ENTSOE), have agreed on a new data policy for the reuse of TSO owned data. This new policy implies that the TSOs release their data on ENTSO-E’s Transparency Platform under an open data licence.

This allows TSO data to be easily reused for new services, research and applications, such as the “Wind Europe Map” and “Tomorrow’s Electricity Map” – just two examples of how the open TSO data can be used to better inform citizens about energy transition and to develop new services and transparency in general. The TSOs and ENTSO-E thus demonstrate their commitment to providing sound and reusable facts and figures to energy market players and the public.
