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.

European power facts

22.01.2019

“Power Facts Europe 2019” is a focused and data-driven report on the dimension, status quo, development and perspectives of key areas of the European energy transition published today by the European Network of Transmission System Operators for Electricity (ENTSO-E). The “Power Facts” are part of a wider ENTSO-E transparency initiative by which ENTSO-E and the transmission system operators (TSOs) aim to provide citizens with factual support to promote the energy transition in Europe and its acceptance.

The “Power Facts Europe” consist of six chapters. The first three represent the common triad of sustainability, market and security of supply, which is supplemented by chapters on infrastructure, customers and the cyber physical grid. Each chapter offers relevant data compilations, mainly provided by the TSO community, that allow a better understanding of important aspects related to the energy transition.

EU supports research on power system interfaces

17.01.2019

After implementing the network codes and the “Clean Energy for All Europeans” package, the European Commission is now funding INTERRFACE under the Horizon 2020 programme. The aim of this research project is to create new connections/interfaces in the power system. INTERRFACE has now been launched and will run for three years with a budget of €21m. It involves 42 partners from grid and market operators, aggregators, service and technology providers as well as universities.

The consortium includes the European Network of Transmission System Operators for Electricity (ENTSOE) and the two TSCNET shareholders ELES, the Slovenian transmission system operator (TSO), and Transelectrica, the TSO from Romania. Together with their partners, they plan to develop an Interoperable pan-European Grid Services Architecture to serve as an interface between customers and power system operators – TSOs and distribution system operators (DSOs) – to allow seamless, transparent and non-discriminatory exchange of energy services.

INTERRFACE is intended to demonstrate the added value of data exchange between all players involved in the value chain of the electricity system, and this from local, regional to EU level. This would be a first in the energy sector. INTERRFACE should also enable TSOs, DSOs and customers to fully exploit and coordinate the potential of decentralised energy resources.

APG and ENTSO-E comment on frequency drop

16.01.2019

Last Thursday, 10 January 2019, at around 9 p.m., a deviation from the 50Hz mid-frequency to 49.8Hz was registered in the Continental European (CE) Power System which comprises the synchronised transmission grids of 25 countries. As foreseen in such cases, immediate collective actions have been taken by the transmission system operators (TSOs) of the CE Regional Group and the underfrequency was rectified within a few seconds. The incident was clearly sufficient to alert the TSOs, but at no time did it jeopardise the European security of supply.

Nevertheless, there have been reports in some Austrian media about a potential interruption of the European electricity supply, comparable to the event of November 2006, when ten million households in France were disconnected from the grid as a precautionary measure. These press reports have provoked reactions from TSCNET shareholder APG, the Austrian TSO, and the European Network of Transmission System Operators for Electricity (ENTSO-E), who both stated that the comprehensive technical analysis is still pending but that there was no risk of a major power failure at any time.

APG has already made initial statements on the incident. According to APG, the cause was most likely a combination of several circumstances, but the decisive factor was probably a data error at another TSO at a transfer point on the Austro-German border. This occurrence could not be compared with that of 2006, when line overload was the reason.

APG and ENTSO-E respond to press reports on the frequency drop in the CE power system and confirm permanent security of supply

TSO proposals for balancing market integration

20.12.2018

To pave the way for a well-functioning energy union, there are eight European network codes: regulations that are intended to promote the integration and coordination of the various national European energy markets. One of these codes, the Commission regulation establishing a guideline for electricity balancing (EBGL), is intended – as the wording implies – to integrate the national European balancing markets.

Cross-border balancing is crucial for the transmission system operators (TSOs) to continuously ensure that the grid frequency is kept within a defined security range and that the required level and quality of power reserves are maintained. The European TSOs have now substantially advanced the guideline implementation by submitting six proposals for balancing market integration and the creation of platforms for the exchange of balancing energy products to the competent national regulatory authorities (NRAs).

With the assistance of the European Network of Transmission System Operators for Electricity (ENTSOE), these proposals have been developed in close cooperation between all TSOs and consulted with stakeholders. Laurent Schmitt, ENTSO-E Secretary General, is convinced that the realisation of the TSO proposals will create a level playing field for all market participants and thus lead to increased cross-border participation, supply security, competition and share of renewable energy. Consequently, Mr Schmitt identifies a “true ‘win-win-win situation‘, good for customer, the environment and the economy”.

InnoGrid 2019 on cyber-physical grids

19.12.2018

A few days before Christmas, the European Network of Transmission System Operators for Electricity (ENTSO-E) pointed out one of the most important dates in the coming year for innovative network concepts: InnoGrid 2019, which will take place on 13 and 14 May in Brussels, Belgium.

In recent editions, InnoGrid has proven to be the key European event for electricity grid innovation and there is no reason why it should be any different this time. The prestigious annual event is organised jointly by ENTSO-E and the European Distribution System Operators for Smart Grids (EDSO). The motto of InnoGrid 2019 is: “Connecting Physics and Digits: Power Platforms on the Rise”. What’s the whole issue? It is about physical networks and their permeation with information and communication technologies, transforming the energy system into a cyber-physical system.

How can it be ensured that digitisation will reach its full potential? And what is the best possible interaction between transmission system operators (TSOs) and distribution system operators (DSOs)? CEOs of the industry will answer these and other questions and present their respective innovation strategies. At InnoGrid 2019 you will get acquainted with today’s emerging power platforms and have the opportunity to discuss the necessary regulatory, political and financial framework conditions. Sponsoring opportunities for InnoGrid 2019 are already available and the calls for applications will be sent out shortly.

ENTSO-E and EDSO are hosting the 8th annual InnoGrid conference on innovation in electricity networks from 13-14 May in Brussels

Publications on HDVC reliability and the balancing market

13.12.2018

The European Network of Transmission System Operators for Electricity (ENTSO-E) has adopted positions on two systemically relevant topics for the European energy market: the electricity balancing market and the improvement of high-voltage direct current (HVDC) system reliability. Two respective papers have been released by ENTSO-E. The first, a balancing guideline, gives a simplified overview of the target model of the European balancing energy market and explains the most important concepts and processes associated with this market and the platforms for the exchange of balancing energy products. In addition to the focus on the interaction of the different balancing processes, the legal framework of the target model is also briefly outlined.

In its position paper on HDVC reliability, ENTSO-E recognises HDVC as an increasingly important method of transmitting large quantities of electrical energy for the Europe-wide transmission grid. As new HVDC connections play a key role in the future development of the continental transmission system, the reliability, availability, compatibility and robustness of the technology will be crucial for market and system security. For future challenges, high system security and the needs of an efficient European integrated market, it is essential that the owners of HVDC installations, together with other relevant HVDC stakeholders, focus not only on technology innovation but also on further process development, HVDC network integration studies and the maintainability to be carried out by transmission system operators (TSOs). ENTSO-E strongly supports more efficient cooperation between all HDVC players.

Satellite technology for grid optimisation

30.11.2018

Power lines run above and below the ground or also under the sea – hence, the business of the European transmission and distribution system operators (TSOs and DSOs) tends to be ground-based. Sometimes, however, a glimpse into the sky might inspire us to find new approaches to make the European power system even more efficient and reliable in the future.

This is perhaps how representatives of the European Network of Transmission System Operators for Electricity (ENTSO-E) and the European Distribution System Operators Association (EDSO) have come to the question of how satellite applications can support the European power grid and its evolution. Anyway, together with the European Space Agency (ESA) the two operator organisations have entered on 29 November into a cooperation on the deployment of satellite technology for grid optimisation.

The cooperation will be implemented through ESA’s Business Applications programme, designed to support the development of new services using data from space assets. Satellite applications can support power grids in many areas, e.g. facilities management, two-way communication between smart meters and operators, prediction of consumption or generation peaks, development of Internet-of-Things related services, or the use of virtual power plants.

Nick Appleyard, Head of ESA’s Business Applications Department, highlights the potential of satellite communication for the allocation of renewable energy generation volumes and grid balancing. Laurent Schmitt, Secretary General of ENTSO-E, agrees and sees “opportunities to enhance real-time grid management through using available space technologies”. Mr Schmitt concludes: “This cooperation will identify business cases where both sectors can support each other and deliver benefits for the European consumer.”

Winter 2018/19: supply largely secured – monitoring required

28.11.2018

Where are congestions most likely to occur? What are the most important risks to the stability of the pan-European electrical transmission system and supply security in the upcoming winter? As every year, the Winter Outlook 2018/2019 – the supply security forecast of the European Network of Transmission System Operators for Electricity (ENTSO-E) – tries to answer these and other significant questions as validly as possible in order to provide a reliable risk assessment for the next European electricity winter.

Good news first: The risks to the security of supply in the approaching cold season are moderate and supply is secured under normal conditions. Nevertheless, close monitoring is required in the event of cold spells. ENTSO-E pays particular attention to an area including Belgium, France, northern Italy, central northern Italy and Slovenia, which is partly due to unforeseen and delayed maintenance of production units in Belgium. In particular in January and February, monitoring will be necessary in the event of outages in connection with low wind and solar energy generation.

The Winter Outlook considers a number of factors that are relevant to safety analysis, such as hydro reservoirs, gas supply and changes in generation. This year’s edition reveals that the decline in conventional generation is persisting, while the increase in installed renewable generation capacity is higher than last winter. As usual, ENTSO-E presents the Winter Outlook together with an overview of the events of previous summer, that was characterised by far above-average temperatures, especially in northern and eastern Europe. This led to some local electricity supply disruptions in the Czech Republic, Croatia and Greece.

TSOs support ENTSO-E to prevent frequency deviations

13.11.2018

The Continental European (CE) Power System which comprises the synchronised transmission grids of 25 countries has been subject to occasional deviations from the 50Hz mid-frequency since late 2017. Each time the deviations originated from the Serbia, Macedonia, Montenegro (SMM) control block, specifically from the control areas of Kosovo and Serbia – an example of how a regional conflict in an interconnected system can have pan-European impacts. The European Network of Transmission System Operators for Electricity (ENTSO-E) has consistently undertaken efforts to find a political solution to the problem, and the CE transmission system operators (TSOs) have pledged their support in addition to the technical measures they are implementing anyway to limit the deviations.

Obviously, the problem is not only an issue for ENTSO-E and its members, but also of interest to the general public. It needs to be solved in order to keep the system consistently stable, to avoid further time deviations in electronically controlled watches, to limit financial effects, and ultimately to avoid a potential blackout in Europe. Considering the next winter period, this should happen in the short term. ENTSO-E is therefore in close and continuous exchange with the two responsible TSOs, EMS from Serbia and KOSTT from Kosovo, and has the task of facilitating a solution between the TSOs.

ENTSO-E’s Regional Group CE, which represents all transmission system operators of the 25 countries in the CE synchronous area, voted last week on a proposal to put an end to the deviations. The suggestion aims to provide a basis for a transitional solution and does not impose a principle on either of the two TSOs. ENTSO-E’s proposal was widely supported by the TSOs, although the work-in-progress version of the operational principles could not be approved. ENTSO-E continues its discussions with EMS and KOSTT.
