Way is paved for 400kV line in western Romania

29.07.2020

For more than ten years, the completion of the 400kV Oradea-Békéscsaba overhead line in the far west of Romania has been prevented due to unresolved ownership issues regarding the section Oradea South-Nădab. Because of this, the line could only partially be put into operation, that is between the Romanian town Nădab and the Hungarian town Békéscsaba, near the Romanian-Hungarian border. Now the property situation has been clarified and the Romanian transmission system operator (TSO) and TSCNET shareholder Transelectrica was able to award the building contract for the missing section.

Transelectrica expects the construction work to be completed within twelve months. The commissioning of the last 72-kilometre section and thus the completion of the Oradea-Békéscsaba overhead line will contribute to the closure of the “400kV Ring” in the west of Romania. This project is a priority energy target for Romania, which will significantly improve the operational reliability of the national transmission system and security of electricity supply in the north-west of the country. The new Oradea-Békéscsaba line will also enable Transelectrica to eliminate congestions and thus save considerable costs for grid interventions. Finally, Romania’s interconnection capacity will be increased by 100MW in export and 300MW in import direction, which will not only contribute to compliance with EU regulations, but also make a sustainable contribution to the integration of the European electricity market.

TSOs of the Central SOR submit RCC proposal

29.07.2020

The EU Regulation on the internal electricity market (2019/943) calls for a higher degree of coordination between transmission system operators (TSOs) at regional level. This is to be achieved through the establishment of Regional Coordination Centres (RCCs). Regulation 2019/943 provides that the future RCCs will act more autonomously in terms of risk prevention than the current Regional Security Coordinators (RSCs) like the Munich based TSCNET Services. On 6 April 2020, the Agency for the Cooperation of Energy Regulators (ACER) published a decision on the geographical scope of the RCCs (ACER Decision 10/2020) and defined the so-called System Operation Regions (SORs). The TSOs of each SOR were invited to submit a proposal on the establishment of RCCs to the relevant national regulatory authorities (NRAs).

The 19 TSOs of the Central SOR – including all TSCNET shareholders except the non-EU TSO Swissgrid from Switzerland and also three TSCNET customers – now have submitted their joint proposal for the RCC establishment in accordance with Article 35 of Regulation (EU) 2019/943. It was published by the German Federal Network Agency (“Bundesnetzagentur“).  The TSOs’ suggestion is to develop existing RSCs into RCCs by adapting them to comply with the requirements of the EU Regulation. The TSOs are of the opinion that despite their increased autonomy, the future RCCs should have their grid stability measures confirmed by the TSOs. The respective TSOs concerned should be able to carry out reviews where appropriate and to oppose RCC measures on well-founded reasons. This requires an intensive exchange of information between RCCs and TSOs.

The paper proposes working agreements and service contracts as basis for the TSO-RCC cooperation. The core tasks of the RCCs should remain those of the RSCs, such as security analysis, outage planning coordination, capacity calculation, adequacy forecasts, or grid modelling. In addition, the RCCs should assist TSOs in identifying transmission system extension and modernisation priorities. RCCs should also be involved in assessing the extent to which foreign capacity may participate in national capacity mechanisms. A proposal from the European Network of Transmission System Operators (ENTSO-E), which is still pending, shall define which tasks the RCCs will perform in determining regional reserve capacity and in the regional procurement of balancing power.

New Local Implementation Project under SIDC

09.07.2020

European transmission system operators (TSOs) are committed to the European Energy Union by collectively working towards an integrated European electricity market. A key component for market integration is cross-border Single Intraday Coupling (SIDC), which was introduced as XBID in June 2018. SIDC is designed to increase the overall efficiency of intraday trading through effective competition, increased liquidity, and more efficient use of generation resources. Currently, the markets of 22 countries are coupled through SIDC: Austria, Belgium, Bulgaria, Croatia, Czech Republic, Denmark, Estonia, Finland, France, Germany, Hungary, Latvia, Lithuania, Luxembourg, Netherlands, Norway, Poland, Portugal, Romania, Slovenia, Spain, and Sweden. With the inclusion of the Slovakian Nominated Electricity Market Operator (NEMO) OKTE and TSCNET shareholder SEPS, the TSO from Bratislava, the project also extends to Slovakia.

Within the framework structure of the SIDC, Local Implementation Projects (LIPs) provide for the expansion of the market coupling, and a new project has now been established as LIP 17. The NEMOs and TSOs from the Czech Republic, Hungary, Poland, and Slovakia – the TSCNET shareholders ČEPS, MAVIR, PSE, and SEPS – have proposed to implement SIDC across the borders between Slovakia-Czechia, Slovakia-Hungary, and Slovakia-Poland. The SIDC Steering Committee approved on 7 July and the LIP 17 roadmap will now be elaborated in more detail.

The SIDC solution comprises a common IT system with a shared order book, a capacity management module, and a shipping module. In addition to the TSOs mentioned above, the TSCNET shareholders 50Hertz, Amprion, APG, ELES, HOPS, TenneT, Transelectrica, and TransnetBW as well as the TSCNET customers Creos from Luxembourg and Energinet from Denmark are also part of SIDC.

Successful start of FCR auctions

01.07.2020

The cooperation on regional procurement and exchange of frequency containment reserve (FCR) is a voluntary initiative of eight transmission system operators (TSOs): the six TSCNET shareholders 50Hertz, Amprion, and TransnetBW from Germany, APG from Austria, Swissgrid from Switzerland, and the Dutch-German TSO TenneT, as well as Elia from Belgium and the French TSO RTE. The FCR project is the first regional cooperation for a common market based on the methodology for the exchange of control reserves set out in the EU Guideline on Electricity Balancing. Within the scope of a cooperation model with Amprion, the Luxembourg TSCNET customer Creos is also involved.

The next milestone in the development of the largest European market for primary balancing power reserve has now been reached, as the first D-1 auction for FCR with 4-hour products was successfully conducted on 30 June 2020. This means, the FCR cooperation reduces the product length from one day to four hours and thus the market for primary balancing power is brought closer to real time.

Due to stronger competition between service providers and technologies, the joint auction allows TSOs to procure FCRs at minimum cost to end-users while offering a large common market for all providers of balancing services. It also increases the market attractiveness for short-term flexibility, limits price volatility and improves the security of grid operation by executing cross zonal procurement of FCR. The FCR market, already the largest in Europe, will be extended to western Denmark and Slovenia in the first quarter of 2021, so that with Energinet and ELES two further TSCNET shareholders will broaden the project.

Eurobar for offshore integration

24.06.2020

Those involved in European electricity transmission have clearly understood that the common climate targets up to 2050 call for suitable and forward-looking concepts already today. Although the control area of TSCNET shareholder Amprion is not directly bordering a seashore, the German transmission system operator (TSO) shares nonetheless responsibility for transporting green electricity generated offshore to the consumption centres. Amprion thinks in a pan-European dimension and has developed a concept to integrate offshore electricity into the European power grid in a way that makes an optimal contribution to the European climate goals: The European Offshore Busbar (Eurobar) responds to the fact that the North Sea countries alone want to exploit an offshore potential of around 200GW by 2050.

The concept provides for the new generation of offshore facilities in the North Sea to be designed for connection to an offshore grid already during the early planning stage. Later, they can be gradually interconnected – first at national level and then between the North Sea countries. Through this integration, wind power can be transported flexibly and across borders to where it is needed, thus increasing efficiency and reducing costs as well as the need for additional grid expansion onshore. Dr Hans-Jürgen Brick, CEO of Amprion, emphasises the key role of the trans-European integration of offshore wind power for the future climate-neutral energy system: “Eurobar aims to make a constructive contribution to European plans for offshore development.”

Amprion has benefited from the advantages of an integrated power system for many decades and now, with Eurobar, intends to transfer this integration concept to the offshore grid to create an overall system for onshore and offshore energy. “Eurobar will intensify European collaboration in offshore development,” believes Dr Klaus Kleinekorte, CTO at Amprion. Peter Rüth, the CFO of the TSO, adds: “Eurobar is designed as a partnership.” Consequently, the implementation can be carried out by the respective partners, be it states or grid operators, autonomously. The only condition is, that the technical standards yet to be developed are applied when installing future offshore systems. “We will now be working together with our partners in industry and among network operators on resolving the technical issues and advocating standardisation on a European level,” concludes Rüth.

New IT tools for Europe-wide supply security

08.06.2020

The digitisation of grid operation is constantly increasing and requires continuous optimisation, e.g. in terms of outage planning coordination and adequacy analysis – both aspects are integral parts of the Annual Work Programme 2020 of the European Network of Transmission System Operators (ENTSO-E). Two new IT tools to simplify the cooperation of transmission system operators (TSOs) and allow better anticipation of the balance between supply and demand are available since this spring and currently used by a total of 38 TSOs. Under the coordination of ENTSO-E, the “Outage Planning Coordination (OPC) Pan European Merge Tool” and “Short Term Adequacy forecast (STA) tool” have been developed jointly with the Munich based Regional Security Coordinator (RSC) TSCNET Services playing a leading role in the development of OPC.

Tahir Kapetanovic, Head of the Control Centre of TSCNET shareholder APG, the Austrian TSO, and Chairman of the ENTSO-E System Operation Committee, comments on the latest success: “The cross-border coordination and intensive cooperation of all national TSOs are the preconditions for a smooth functioning of the power supply across the European Union. By means of such jointly developed tools, uniform norms and standards for network operation can truly be implemented into practice.”

The launching of both tools may be considered as further evidence of the well-established pan-European cooperation of European TSOs and RSCs. STA enables a short to medium-term prognosis for load management, which is particularly important in view of the energy transition to compensate for the volatility of renewable power generation with innovative solutions and to integrate them smartly into the system. With the OPC Pan European Merge Tool, concept originally developed by TSCNET Services, the TSOs and RSCs can plan power outages on a regional level, including coordination of maintenance and inspections. Electricity supply and trade are thus ensured despite the necessary shutdowns.

The need for OPC on a pan-European level across the different RSCs and the corresponding concept of a harmonised outage planning process dates back to 2012, when the TSOs of the central and eastern European regions established the TSC (TSO Security Cooperation) area. The Medium-Long-Term Operational Planning (MLTOP) project of the TSC TSOs, which was started at that time, is the origin of the OPC tool. When TSCNET Services emerged in 2015 from the joint TSC TSO office in Munich, the MLTOP project was carried on by TSCNET for prototype and business process development in coordination with the TSC TSOs. In the same year, ENTSO-E launched the TSO Project for Coordination Strategy Implementation with the Regional Security Coordination Initiatives (RSCIs), which was continued later under the EU System Operation Guideline (SO GL). This extended the scope of the MLTOP project from the TSC area to the whole of Europe and it became the foundation of the OPC project.

In December 2017, the prototype resulting from the OPC project, owned and developed by TSCNET, went live on a pan-European scale and provided the initial service to all TSOs and RSCs in Europe. Now the prototype tool has been converted into and replaced by a fully-fledged industrial tool: the OPC Pan European Merge Tool, whose development represents a unique success story for TSCNET services and the associated TSOs. What was once an idea for cooperation in the TSC area has been further developed and prototyped by TSCNET in close cooperation with the TSOs and has now evolved into an industrialised pan-European tool used by the outage planners of 38 TSOs and four other RSCs.

TSCNET Services as a major contributor
The OPC project and its development process is a good example of what can be achieved through intensive cooperation between TSOs and RSCs. TSCNET successfully took the lead in this cooperative effort and managed not only to develop services on a pan-European level, but also to successfully coordinate with other stakeholders (RSCs, TSOs and ENTSO-E) and convince them to be part of the success. The development of the OPC project fits perfectly with the narrative of the definition of TSO, RSC and European coordination: The RSCs provide services to TSOs by setting up business processes and tools with their unique regional and technical expertise, thereby combining the knowledge of the individual TSOs – and if the concept has proven to work, they scale it up for the rest of Europe and centralise the infrastructure if necessary (and requested by ENTSO-E).

TSCNET is indebted to its Service Analytics & Quality Manager and responsible OPC Project Convener, Jayaram Anandha, to Sonja Tomić, Junior Operations Manager, and Jorge Alves, Operations Manager, for their input in the development of this highly efficient tool. The predecessor as OPC Project Convener, Tin Bobetko, and Michalis Stamoulis jointly led the business and data standard development of the OPC prototype tool, which was running perfectly until the industrialised version went live.

Luxembourg integrated into FCR cooperation

01.06.2020

Eight central European transmission system operators (TSOs) cooperate in the regional procurement and exchange of Frequency Containment Reserve (FCR). Their joint FCR project is the first regional cooperation in Europe to implement market harmonisation in accordance with the EU Guideline on Electricity Balancing. The participating TSOs are APG, 50Hertz, Amprion, TransnetBW, and Swissgrid – the Austrian, German and Swiss TSCNET shareholders –, the Dutch-German shareholder TenneT as well as the Belgian TSO Elia and the French TSO RTE. It is intended to extend the joint FCR procurement towards western Denmark, so that the central European TSOs are supplemented by Energinet from Denmark as a non-active member.

Luxembourg was missing in the cooperation so far, but cross-border primary control reserve (PCR) between Germany and Luxembourg is now also possible: Since 1 June 2020, balancing service providers (BSPs) from Luxembourg are participating in the joint tender for FCR cooperation. For this purpose, the TSO Amprion, whose German control area is bordering the Grand-Duchy, and the Luxembourgian TSCNET customer Creos have developed a cooperation model. Under this model, Amprion assumes the role of the connecting TSO, carries out the prequalification of the BSPs, concludes the framework agreement for PCR, and takes over the settlement with the BSPs from the Creos control area.

Since Amprion and Creos operate a joint load-frequency-control area, a pooling of technical units within this common area is permissible. Thus, a pool can include Luxembourgian as well as German units that provide balancing services. This means that a BSP may combine generation units or controllable consumer loads from both countries and offer them collectively on the PCR market.

Amprion Market Report shows encouraging trends

27.05.2020

The intermeshed European electricity market today requires constructive cooperation between all actors and organisations. Amprion, one of the four German transmission system operators (TSOs), considers the efficiency of cooperation at European level a key prerequisite for continental security of supply and the success of the energy transition. For this reason, the TSCNET shareholder was and is involved in numerous regional and European initiatives on system operation, network planning, and market integration. Also, Amprion is an observant analyser of the European market development, especially in the Central Western Europe (CWE) region and annually provides the Market Report for the CWE countries. The 2020 edition for the period 2015 to 2019 has just been released.

The Market Report is based on data from Flow-Based Market Coupling (FBMC) introduced by the six CWE countries (Austria, Belgium, France, Germany, Luxembourg, the Netherlands, and Belgium) in May 2015. By involving the entire regional network in the coupling of electricity markets, FBMC allows TSOs to allocate cross-border capacity and maximise market efficiency without jeopardising grid stability. The Amprion report clearly indicates the progress of the CWE market integration, especially with the following figures: In 2019, price convergence on the day-ahead markets increased by a further 10%, reaching 42%. In other words, in almost every second hour, day-ahead prices in the CWE have been equal because the TSOs succeeded in making sufficient power transmission capacity available to meet the demand of the entire region at the same prices.

Dr. Hans-Jürgen Brick, CEO of Amprion, comments on the positive development: “The Market Report furnishes proof that trade barriers could be decreased during the course of 2019.” Dr Brick places particular emphasis on the efficient and highly interconnected power grids in the CWE region and their “key role in ensuring Europe’s stable and secure energy system”. As regards Amprion’s individual contribution, the TSO was able to further improve the efficiency of its grid and thus strengthen European electricity trading. Whereas in 2018 the share of all active trade constraints caused by Amprion internal elements was 13.7%, in 2019 it was only 7.8%. This is due not only to the ongoing grid expansion measures, but also to the monitoring of overhead lines, which allows more efficient utilisation of the most important power lines.

Generation adequacy in the CWE region within standards

22.05.2020

The Pentalateral Energy Forum (PLEF) provides the framework for regional cooperation in Central Western Europe (CWE) to improve electricity market integration and security of supply. The initiative aims to give political backing to a process of regional integration towards a European energy market. As far as the concrete implementation of impulses from the initiative is concerned, eight transmission system operators (TSOs) of seven countries cooperate in the PLEF, including the TSCNET shareholders APG from Austria, Amprion and TransnetBW from Germany, Swissgrid from Switzerland, the Dutch-German TSO TenneT, and TSCNET client Creos from Luxembourg as well as the Belgian TSO Elia and RTE from France.

The PLEF is subdivided in so-called Support Groups, e.g. covering work on market integration (SG1) and on security of supply (SG2). Within the scope of the SG2 group, the eight TSOs have worked out the third edition of the Pentalateral Generation Adequacy Assessment (PLEF GAA 3.0) and have just published a corresponding report, which summarises the main findings in 71 concise pages. The study, which examines the adequacy of electricity generation in the PLEF region up to the medium-term time horizon (2025), can be considered as significant result of TSO cooperation at regional level.

The main findings are that, under base conditions, sufficient production capacity is available, so that a breach of reliability standards is not to be expected and the adequacy of production in the CWE region will be up to standard by 2025. However, adequacy simulations have also shown that adequacy risks can occur. The electrical system may be exposed to specific situations in which the system safety is under strain. Additional unforeseen events in such situations can put even greater pressure on daily system operation, which may require the activation of special measures.

Nordic Power Solutions Report

29.04.2020

The Nordic transmission system operator (TSOs) of Finland, Norway, Sweden, and the Danish TSCNET customer Energinet have updated their 2018 report “Solutions for a changing Nordic power system”. The Solutions Report 2020 provides an overview of the joint Nordic TSO projects that have been identified as crucial to address the challenges in the Nordic energy system.

As in the rest of Europe, the Nordic power system is undergoing the most significant changes since the liberalisation of the electricity markets, and here, too, these changes are mainly based on a new power generation mix with volatile generation and distributed resources. The Power Solutions Report 2020 draws a common picture of the progress of the new solutions in the Nordic power system that respond to these changes. In addition to reporting on the projects, the report also features comments from stakeholders on the tasks and the challenges they still see in the Nordic power grid.
