Variable shunt reactor for SINCRO.GRID

03.12.2019

The two transmission system operators (TSOs) and TSCNET shareholders ELES from Slovenia and HOPS from Croatia are cooperating in SINCRO.GRID. This cross-border smart grid initiative is coordinated by ELES and comprises in addition to the TSOs also two distribution system operators (DSOs) from both countries. The objective of the European Project of Common Interest (PCI) is to optimise the efficiency of the respective national transmission systems by means of advanced technologies and innovative data processing methods.

Since the substantial allocation of EU funding to SINCRO.GRID under the Connecting Europe Facility (CEF) programme in 2017, the project has made significant progress. A vital component of SINCRO.GRID is optimising and installing compensation devices for reactive power control, e.g. variable shunt reactors, which are used in high-voltage transmission systems for voltage stabilisation during load variations. Now the ELES substation in Divača in south-eastern Slovenia has been equipped with such a technically advanced device manufactured by Siemens in Austria. The assembly work is in full swing and is expected to be completed by 12 December. Preparatory work for commissioning will then commence immediately.

Another major component of SINCRO.GRID is a dynamic thermal rating system for power grid operating limits. The aim is to evaluate marginal capacities of transmission system components considering weather influences and thus to improve operational safety and utilisation of overhead lines and transformers. In addition to hard- and software in control centres, atmospheric measuring devices, which are installed directly at the pylons, are also part of the system. Corresponding tests of innovative weather stations are underway. Last week, the substructure for the weather station on the Kleče-Divača overhead line was field tested.

Winter outlook: RSC monitoring for supply security

28.11.2019

Every year at the end of November, the European Network of Transmission System Operators for Electricity (ENTSO-E) publishes its supply security forecast for the coming winter season. Like its predecessors, Winter Outlook 2019/2020 is a concise document that provides valuable information on where bottlenecks are most likely to occur, or which are the main risks to the security of the pan-European electrical transmission system. The Outlook forecasts have been carefully calculated on the basis of a comprehensive database to provide a reliable risk assessment for the next European electricity winter.

The main positive message is that general European security of supply is ensured under normal conditions. Nevertheless, the Outlook indicates that in the event of cold spells, i.e. temperatures 10 degrees below average, combined with unforeseen outages and low renewable generation, there are potential risks in Belgium and France in January 2020. Under these extreme conditions, both countries would be heavily dependent on imports and in some cases on available out-of-market measures. Furthermore, close monitoring would be required, and ENTSO-E explicitly requests in such cases the support of regional security coordinators (RSCs), such as the Munich-based TSCNET Services.

As usual, ENTSO-E presents the Winter Outlook together with the Summer Review 2019, an overview of last summer’s events. Some heat waves were registered, but without any impact on the power supply.

ENTSO-E’s MAF 2019 is out now

23.11.2019

The European Network of Transmission System Operators for Electricity (ENTSO-E) has released the new 2019 edition of the Midterm Adequacy Forecast (MAF). In this context, “adequacy” refers to the balance between electricity generation and demand and the forecast is based on a comprehensive mathematical analysis of future pan-European supply security over the period up to 2021 and 2025. The MAF examines not only the interdependencies of supply and demand, but also of storage, climatic conditions, and interconnection capacity. This year, the data granularity and quality were further improved, in particular, with information on thermal generation, an improved hydrological database and a new calculation methodology for demand time series.

The results of MAF 2019 show a low risk for adequacy. However, the MAF also underlines the increasingly important role of cross-border cooperation between transmission system operators (TSOs) in promoting adequacy throughout the interconnected pan-European electricity system. As in the previous issue, MAF 2019 includes a low carbon scenario that considers the impact of the decommissioning of coal-fired plants by 2025. Here the results for some market areas directly or indirectly affected show increased risks. Sources of flexibility such as demand side patterns, storage, interconnections and enhanced and smarter integration of renewable and distributed energy sources are thus required.

The MAF is part of the broader 10-year Network Development Plan (TYNDP), which assesses system needs up to 2040. The results of MAF 2019 will be open to public consultation until 13 January 2020. In addition, ENTSO-E will organise a public webinar on 4 December to discuss the MAF results.

TYNDP 2020 Scenario Report

13.11.2019

The Ten-Year Network Development Plans (TYNDPs) are published every two years by the European Network of Transmission System Operators for Electricity (ENTSO-E) and for gas (ENTSOG) with the participation of the respective member transmission system operators (TSOs). The TYNDPs support the European Commission in selecting Projects of Common Interest (PCIs) to be subsidised by European funds.

An EU regulation requires the ENTSOs to develop scenarios for their TYNDPs, and with the TYNDP 2020 the ENTSOs have designed these scenarios jointly for the second time. This cooperation makes sense because the scenarios not only serve to test the future needs and projects of the electricity and gas infrastructure, but also to investigate the interactions between gas and electricity grids in order to assess the infrastructure of a hybrid energy system.

The supply and demand data obtained from TSOs have resulted in the “National Trends” scenario, the central policy-based scenario that takes into account Member States’ national energy and climate plans as well as EU climate targets. The “Global Ambition” and “Decentralised Energy” scenarios are developed as full energy scenarios (not only for gas and electricity) and are in line with the objective of the Paris Convention. “These scenarios represent a comprehensive, reliable and contrasted set of possible energy futures that will allow the ENTSOs to perform a sound assessment of European infrastructure projects in the TYNDPs,” comments Laurent Schmitt, Secretary General of ENTSO-E.

The “TYNDP 2020 Scenario Report” featuring the draft versions of the scenarios has now been released by the ENTSOs and a formal public consultation on the scenarios will be launched shortly and will run until January. On 5 December, the ENTSOs will organise a public workshop in Brussels to present the TYNDP 2020 Scenario Report.

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.

PROMOTioN for a North Sea transmission grid

08.11.2019

“PROgress on Meshed HVDC Offshore Transmission Networks” is a very precise project description but also a bit lengthy. In contrast, the dynamic acronym “PROMOTioN” refers quite well to the ambitions that the consortium members contribute to the research project. General goal of PROMOTioN is the further development of innovative technologies relevant for the deployment of meshed offshore HVDC nets. The more specific objective is to improve cooperation between grid operators and major suppliers of technical architecture and interoperable technologies to accelerate offshore HVDC grid development. PROMOTioN is the largest energy project funded under the EU Horizon 2020 programme, with a consortium of 33 partners from 11 countries, including the two TSCNET shareholders Energinet, the Danish transmission system operator (TSO), and TenneT, the Dutch-German TSO.

A report by PROMOTioN has just been published (“Regulatory and financing principles for a meshed HVDC offshore grid”) summarising the principal findings for the design of a legal, regulatory and financial framework for cross-border HVDC offshore connections. The report provides recommendations for policy-makers and other stakeholders for overcoming regulatory and financial obstacles to the realisation of a North Sea transmission system. The key conclusion of the report and of the whole project is that the North Sea riparian states need to establish a harmonised legal and economic framework to fully exploit the potential of a meshed offshore grid in the North Sea.

A distinction is made between short-term and long-term recommendations, each of which is presented very concisely. Short term recommendations include the improvement of governance and regulation of the internal market for (offshore) electricity, optimisation of innovation financing, support for early communication of all parties involved and the formalisation of cross-border cost allocation (CBCA) as a binding contract. The latter aspect is regarded as one of the most important pillars in the economic framework. The most significant long-term recommendation is that EU member states, third countries and the EU should consider adopting a North Sea Treaty containing the objectives and principles of the offshore grid.

Tim Meyerjürgens, COO at TenneT, comments on the PROMOTioN project: “The development of a cross-border HVDC grid is one of the most promising opportunities for a sustainable energy future in Europe. TenneT is cooperating closely with other TSOs to develop the idea of a meshed and efficient offshore grid in the North Sea, which requires the creation of a common regulatory framework. PROMOTioN’s research shows the way to make this happen.”

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.

RSC Conference 2019: Rush to Copenhagen

08.10.2019

The weather turned out typically Nordic with quite stormy wind and some rain, but otherwise host Nordic RSC could be more than happy about a great success and a fruitful gathering of our industry – about 250 participants from all over Europe came to the third “RSC Conference” today in the Danish capital of Copenhagen. The event was staged by Nordic RSC at the Crowne Plaza Hotel, located in the Copenhagen Towers, which also house the offices of the Regional Security Coordinator (RSC) of the power transmission system operators (TSOs) of Denmark (TSCNET shareholder Energinet), Finland (Fingrid), Norway (Statnett), and Sweden (Svenska Kraftnät).

One of the key sentences fell quite early: “Nobody knows the future, but it will be electric!” In the European energy system that is already interconnected and will become even more so in future, coordination of cross-border electricity flows is one of the most crucial tasks for TSOs. To a large extent, this task is performed by Europe’s RSCs, with Coreso (based in Brussels) and TSCNET Services (Munich) as pioneers from 2013 onwards. In 2015, SCC for south eastern Europe followed in Belgrade and in 2016, Baltic RSC as well as Nordic RSC were established.

A good idea becomes a tradition
The RSCs have been holding conferences on system security since 2017, co-organised by the European Network of Transmission System Operators for Electricity (ENTSO-E). TSCNET hosted the first RSC conference entitled “ElSeC” (Electricity Security Coordination) in Munich and one year later Coreso invited to “Power Coordination Europe” in Brussels.

The motto of “RSC 2019” was “Act locally, coordinate regionally, think European”. The event resulted in a closing speech by the CEO of the Finnish TSO Fingrid, Jukka Ruusunen, discussing how RSCs support efficient markets that in turn support security of supply. This core discussion was complemented by other general panel discussions and also by parallel, partly interactive sessions to cover as many interesting and relevant topics as possible. The topics were, for instance, “The Green Transition: The reason for change and innovation in TSOs”, “Ensuring the right competences in an RSC perspective”, “Critical Grid Situation Communication”, “Regional adequacy forecasting” or “Balancing projects and reserve sizing”. The key speakers came from the industry, EU institutions, markets and civil society.

Thomas Egebo, CEO of TSCNET shareholder Energinet, the Danish TSO, welcomed the participants and illustrated the importance of the regions using the example of the Nordic region. The ENTSO-E strategy paper on “Enhanced TSO coordination for Europe” was presented by Joachim Vanzetta, Director System Control at the German TSO and TSCNET shareholder Amprion and Chair of the ENTSO-E Board. Eryk Kłossowski, CEO of the Polish TSO PSE, and Ben Voorhorst, COO of the Dutch-German TSO TenneT – both are TSCNET shareholders – participated together with colleagues from further TSOs in the general discussion: “TSO regional cooperation and establishment of RCCs – learning from best practices”. This discussion was moderated by Laurent Schmitt, the Secretary-General of ENTSO-E.

Increasingly complex with rapidly rising requirements
Maik Neubauer, one of the two Managing Directors of TSCNET Services, held a presentation on “RSC complexities and future challenges”, focusing on the intricacy of the challenges faced by RSCs in the continuous implementation of services, in RSC collaboration and in the adaptation and integration of requirements from the EU “Clean Energy for all Europeans Package” (CEP).

On the conference website, all speeches and discussions were broadcast via live stream. Soon all presentations will be available for download as well as numerous photos from the event. All good things come in threes, as the saying goes. The third edition of the RSC Conference was indeed great, but we are all the more looking forward to next year.

Around 250 participants attended this year’s RSC Conference on 8 October in Denmark’s capital Copenhagen

First cables of ALEGrO installed

27.09.2019

The “Aachen Liège Electricity Grid Overlay” (ALEGrO) will be the first direct interconnector of the German and Belgian electricity grids. Its transmission capacity of 1,000MW is going to significantly increase cross-border electricity flows and security of supply in the regions surrounding the new converter stations at the respective ALEGrO end points, Niederzier in Germany and Lixhe in Belgium. The European Project of Common Interest (PCI) is jointly being implemented by TSCNET shareholder Amprion, one of the four German transmission system operators (TSOs), and the Belgian TSO Elia.

In the summer of 2019, several teams were working simultaneously at different points along the 41km-long ALEGrO section in Germany on the installation of the conduit system for the underground cables. Underground cabling is used exclusively for the entire German-Belgian power bridge. Due to the dry summer, construction work on the DC link has progressed rapidly: 60 percent of the cable conduits have already been completed. Amprion is now beginning to pull the 320kV cables successively into the conduits, initially in Niederzier, where the construction of the new ALEGrO converter plant is also progressing well.
