HOPS commissions variable shunt reactor

22.01.2020

A further step for the successful implementation of the Croatian-Slovenian smartgrid project SINCRO.GRID has been taken. The European Project of Common Interest (PCI) aims at optimising the efficiency of the Croatian and Slovenian electricity transmission grids through the application of advanced technologies and innovative data processing methods and is carried out by the two TSCNET shareholders ELES, the Slovenian transmission system operator (TSO), and HOPS from Croatia.

At the beginning of December 2019, the ELES substation in Divača has been equipped with a variable shunt reactor, an effective compensation tool for reactive power control. Now HOPS has put the same technically advanced system into operation at its substation in Mraclin near Zagreb. With this, HOPS has concluded the first stage of SINCRO.GRID. After the implementation of additional measures and devices, including a static VAR compensator, the Croatian TSO will be able to actively manage the reactive power flows in the Croatian power grid. This will solve problems of overloads in the long term and thus have a positive effect on grid stability and security of supply for customers.

New EU Electricity Regulation in place

17.01.2020

With the beginning of 2020, the recast of the European Electricity Regulation on the internal market for electricity (EU/2019/943) came into force. The regulation is important for the new electricity market design, which was adopted as part of the “Clean Energy for All Europeans Package” and aims at realising the European Energy Union with common market rules and an efficient and high-performing cross-border infrastructure.

The regulation sets out the basic principles for an efficient electricity market and should allow for improved integration of national markets. It should also create greater capacity for cross-border trade, thereby providing better access to renewable energy. As far as the business of transmission system operators (TSOs) is concerned, rules for better coordination and closer transnational cooperation are the core of the regulatory framework. Furthermore, the functions and tasks of the regional service coordinators (RSCs) are clearly specified.

Already on 10 January the four German transmission system operators (TSOs) 50Hertz, Amprion, TenneT and TransnetBW had submitted their draft scenario framework for the 2035 (2021) Network Development Plan (NEP) to the Federal Network Agency (BNetzA). With this, they want to “contribute to the success of the energy turnaround and the achievement of the climate protection goals”.

TERRE platform launched

07.01.2020

The project “Trans European Replacement Reserves Exchange” (TERRE) is dedicated to implementing the exchange of replacement reserves (RRs) under the EU guideline on electricity balancing. The objective of TERRE is to establish the European RR balancing energy market via an RR platform and to create uniform conditions for market participants. TERRE has been confirmed by the European Network of Transmission System Operators for Electricity (ENTSO-E) as the European platform for the exchange of balancing energy from RRs and is closely monitored by national regulatory authorities and the Agency for the Cooperation of Energy Regulators (ACER).

TERRE involves eight European transmission system operators (TSOs). The three TSCNET shareholders ČEPS from the Czech Republic, PSE from Poland and Swissgrid from Switzerland are complemented by RTE (France), National Grid (United Kingdom), Terna (Italy), REN (Portugal) and Red Eléctrica de Espaňa (Spain). A further six TSOs with observer status include the TSCNET shareholders MAVIR from Hungary and Transelectrica from Romania.

The TERRE platform was launched on 6 January 2020. The platform ensures cost-effective balancing energy with service availability within 30 minutes in a European setting. ČEPS was the first TSO to connect to the platform, and is currently also the only one. Further members will follow. “The launch of TERRE represents the completion of several years of effort, from defining business rules to developing an IT solution to testing the system with market participants in Europe,” explains Zbyněk Boldiš, Member of ČEPS’ Board of Directors.

New RSC to be established in Thessaloniki

23.12.2019

As reported by the European Network of Transmission System Operators for Electricity (ENTSO-E), significant progress is being made on pan-European coverage with regional security coordinators (RSCs). The transmission system operators (TSOs) of the South-East Europe and Greece-Italy Capacity Calculation Regions (CCRs), namely ESO-EAD (Bulgaria), IPTO (Greece), Terna (Italy) and TSCNET shareholder Transelectrica, the TSO from Romania, have agreed to establish a new RSC in the northern Greek city of Thessaloniki.

The new company will provide all regional RSC services for both CCRs according to the requirements of the EU guideline on capacity allocation and congestion management (CACM). In line with the experience gained in other CCRs, the RSC in Thessaloniki will promote regional TSO cooperation and strengthen system and market operations. The further development of the plans will be reported in the course of 2020.

TSO proposals on capacity balancing submitted

20.12.2019

In December 2017, the European Commission Regulation establishing a guideline for electricity balancing came into force. The European transmission system operators (TSOs) were given two years to prepare two proposals aimed at promoting market integration through the procurement and use of standard products for capacity balancing in an efficient, economic and market-based manner. Considering feedback from stakeholders, public consultations and workshops, these two proposals have now been submitted by the European Network of Transmission System Operators for Electricity (ENTSO-E) to the Agency for the Cooperation of Energy Regulators (ACER).

The “Proposal for a methodology for co-optimised allocation process of cross-zonal capacity for the exchange of balancing capacity or sharing of reserve” specifies how cross-zonal capacity should be allocated in a single optimisation process to bids for energy exchange as well as for the exchange of balancing energy or the sharing of reserves. The process suggested involves contracting on a day-ahead basis and meets the requirements of the “Clean Energy for All Europeans Package”.

The “Proposal for a list of standard products for balancing capacity for frequency restoration reserves and replacement reserves” details the minimum harmonisation criteria for the exchange of balancing capacity set by all TSOs. To respect the specific conditions of each region, additional characteristics may be defined and harmonised by two or more TSOs deciding to jointly provide balancing capacity.

ENTSO-E stresses that substantial work still needs to be done on the implementation and application of these proposals. Close interaction between neighbouring TSOs is essential for the establishment of balancing capacity cooperation.

Multi Regional Coupling expanded by the end of 2020

17.12.2019

The Multi Regional Coupling (MRC) of the European electricity market is to be substantially enhanced by connecting the so-called 4M Market Coupling Countries (4M MC), i.e. the Czech Republic, Hungary, Romania and Slovakia, to the Europe-wide MRC. This will establish Single Day-Ahead Coupling across 23 European countries.

In preparation for this market integration, the so-called Interim Coupling Project (DE-AT-PL-4M MC Project) was launched. It has now completed the design phase and is entering the implementation phase. This provides the Nominated Electricity Market Operators (NEMOs) and transmission system operators (TSOs) from Austria (APG), Germany (50Hertz, Amprion, TenneT, and TransnetBW), Poland (PSE) and the 4M MC countries (ČEPS, MAVIR, Transelectrica and SEPS) with a sound basis for announcing the MRC inclusion for the third quarter of 2020.

The AT-PL-4M MC Project introduces implicit capacity allocation based on Net Transfer Capacity (NTC) at six borders (PL-DE, PL-CZ, PL-SK, CZ-DE, CZ-AT, HU-AT). The competent National Regulatory Authorities (NRAs) welcome the progress made and the synergies from the project, which will facilitate the introduction of Flow-Based Market Coupling in the Core Capacity Calculation Region (Core CCR), which is the ultimate target.

The AT-PL-4M MC project for integrating Czechia, Hungary, Romania and Slovakia into MRC has entered the implementation phase.

Final MIGRATE conference

10.12.2019

The MIGRATE project (“Massive InteGRATion of power Electronic devices”) is the largest TSO project funded by the European Commission. It was launched in 2016 in the framework of the Horizon 2020 programme. Among the 23 partners of the consortium from 13 European countries are twelve universities/labs, one manufacturer and ten transmission system operators (TSOs), including the TSCNET shareholders Amprion (Germany), ELES (Slovenia) and the Dutch-German TSO TenneT. Under the coordination of TenneT, the partners have researched technology-based solutions for an optimised linking of electricity generation and consumption by means of power electronics.

After four years of intensive work, the MIGRATE project will be successfully concluded by the end of 2019, implying that all project partners have developed innovative solutions in their respective areas of responsibility to gradually adapt the pan-European high-voltage AC transmission system to the requirements resulting from the increasing share of renewable energies and power electronic devices. At a final conference on 4 December in Brussels, the individual outcomes were presented to colleagues and anyone wishing to learn more about the power system stabilisation and grid monitoring capabilities. The keynote speech was given by Laurent Schmitt, Secretary General of the European Network of Transmission System Operators for Electricity (ENTSO-E).

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.
