Awards for ELES smart grid projects

30.07.2020

The International Smart Grids Action Network (ISGAN) is a technology cooperation programme on smart grids by the International Energy Agency (IEA). ISGAN provides a strategic platform to raise awareness and to stimulate action by high level governments for accelerated development and deployment of smart and clean electricity grids around the world. ISGAN initiatives include the annual ISGAN Award of Excellence in “Digitalization Enabling Consumer Empowerment”. On 28 July, the jury announced the winners of the 6th ISGAN Award, which focuses on digitisation at global level and for which nominations have been received from around the world. The first and second prizes were awarded to two projects in which TSCNET shareholder ELES, the Slovenian transmission system operator (TSO), is significantly involved.

The first place goes to the NEDO project, a Japanese-Slovenian initiative whose main partners, besides ELES, are the Japanese New Energy and Industrial Technology Development Organisation (NEDO) and the multinational conglomerate Hitachi. The NEDO project introduces integrated and centrally managed cloud-based solutions to make better use of the existing network and provide customers with a higher quality electricity supply and the opportunity to actively participate in electricity markets and systemic services. ELES decided at the end of 2015 to participate in the project, whose main responsible partner, the namesake agency NEDO, received the award on behalf of the consortium.

The award for FutureFlow, which took second place, was received by ELES itself. The international project was conceived by ELES experts and involves twelve partners from eight European countries. The project implements innovative e-trading solutions for smart cross-border balancing and redispatching in the control areas of four central and southern European TSOs, which are all shareholders of TSCNET. Besides the project leader ELES, the other TSO participants are APG from Austria, MAVIR from Hungary, and Transelectrica from Romania. FutureFlow was launched in 2016 and successfully concluded in December 2019. Pilot tests in real time have proven that also small businesses and power generation units can be a reliable source of flexibility to maintain the balance in the electricity system. The project was funded by the EU under the Horizon 2020 programme, in fact, it was the largest research project financed under Horizon 2020.

The ISGAN Award 2020 is exceptional in that it is the first time that one company receives two awards. After the announcement, the CEO of ELES, Aleksander Mervar, commented that with these two awards, ELES has obtained great international recognition for its activities in the field of innovation and development of smart networks. Mr Mervar complimented the partners in both consortia. By dedicating the two awards to all those who participated in both projects, he acknowledged their outstanding performance.

APG: Resilient and good for economy

10.07.2020

At a press conference, Gerhard Christiner and Thomas Karall – CTO and CFO of the Austrian transmission system operator (TSO) APG, respectively – together with Anna Kleissner, member of the board of the Vienna-based Economica Institute of Economic Research, looked back on the last months of grid operation during the Corona period. COVID-19 confronted the TSCNET shareholder with a number of challenges, each of which had to be met in a short period of time: e.g. the decline in electricity consumption, historically low electricity prices, power plant capacities dropping out of the market, or changes in working methods at the TSO.

“This crisis has shown us that we as a system operator must always be prepared for the unforeseen. This includes supply shortages in cases where too little electricity is generated or the grid capacities are insufficient for electricity transmission,” comments Gerhard Christiner, who also assures: “After four months of the Corona pandemic in Austria, we can conclude that the electricity supply has passed this test and was secure at all times.”

However, for the two APG managing directors, the future is what matters most, and in this respect, the TSO’s investments play an important role for the national economy. The integration of renewable energy requires grid extension, and APG will invest €350m in the Austrian economy this year to increase grid capacities. This supports both, the energy transition and the Austrian economy. “With the decline in economic output at the beginning of the year, investments in the domestic economy are all the more valuable now because they represent a real ‘turbo boost’,” states Thomas Karall. This is supported by a recent independent study carried out by ECONOMICA, which indicates that the investments have a domestic value added of €205.7m. “With every euro generated in the construction industry, a further €2.4 in value added is created in the rest of the economy,” explains Anna Kleissner.

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.

Karall: “All-time high for Austrian power exports”

30.06.2020

An exceptionally good water supply and wind peaks combined with low consumption during the night hours were the preconditions for a record, which TSCNET shareholder APG, the Austrian transmission system operator (TSO), registered between 10:30 and 10:45pm on 15 June 2020: A total of 3,943MW of electricity flowed abroad via the APG transmission grid during this quarter of an hour, more than ever before in history. Also in a European perspective, this capacity of nearly 4,000MW is considerable, as it represents about half of the Austrian peak consumption during the summer or almost twice the generation capacity of all Austrian Danube power plants.

“This figure marks a historic peak. Even though it is only a snapshot, it shows how volatile and unpredictable the new world of electricity and energy is,” comments Thomas Karall, CFO of APG. Before an import or export can be processed via APG’s transmission infrastructure, a detailed analysis of the expected electricity flows is required. Often, renewable production plants in Europe (including Austria) must be throttled due to insufficient grid capacities. “This underlines the particular importance of grid expansion and development projects for the success of the energy transition – because every MWh produced from renewables that is not used is a terrible loss,” notes Karall.

The all-time high clearly indicates how sensitive electricity management has become. While in the past few days generation surpluses in Austria had to be partially curtailed, only a few weeks earlier high imports and the start-up of conventional power plants had been necessary due to low winds and low water levels in the hydropower plants. Thomas Karall expects this situation to remain the same for the near future: “In certain situations generation from renewables has to be curtailed or conventional thermal power stations have to be powered up. This will be necessary at least until we dispose of an appropriate grid infrastructure with sufficient capacity and an adequate storage infrastructure.”

On 15 June, APG recorded an all-time high in exports with almost 4,000MW of exported electricity (picture showing Thomas Karall: Karl Michalski / APG)

ENTSO-E pays tribute to the work done for IT tools

21.06.2020

As already reported in our news blog, the pan-European IT tools for Outage Planning Coordination (OPC) and Short-Term Adequacy (STA) are operational since the end of March and the end of May 2020, respectively. OPC and STA are services provided by Regional Security Coordinators (RSCs) and transmission system operators (TSOs) to increase the operational security of Europe’s power system. The OPC tool allows all five European RSCs and 38 TSOs to coordinate outage planning on a weekly basis, while the STA tool provides them with daily calculations based on generation and demand forecasts of all ENTSO-E member TSOs. These calculations help to identify possible adequacy deficiencies for the coming week.

The tools that now work are based on prototypes developed by the two major European RSCs out of the five. The pilot of the OPC tool was created by TSCNET Services in Munich, Germany, while the STA tool is based on a prototype of CORESO, based in Brussels. Both tools run on the ENTSO-E Communication and Connectivity Service Platform (ECCoSP) and demonstrate the continuing commitment and efforts of the entire TSO community: TSOs, RSCs, and ENTSO-E.

Tahir Kapetanovic, Head of the Control Centre of TSCNET shareholder APG, the Austrian TSO, and Chairman of the ENTSO-E System Operation Committee, considers cross-border coordination and intensive cooperation to be essential for the smooth functioning of the European power system. “Jointly developed pan-European IT tools such as the OPC and STA tools, allow uniform norms and standards for network operation to be put into practice.”

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.

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.

€30m for substation upgrade in Lower Austria

19.05.2020

The grid infrastructure of TSCNET shareholder APG, the Austrian transmission system operator (TSO), must comply with the changes in the power system. The APG projects in this regard are essential for the success of the energy transition and indispensable for Austria’s secure future electricity supply. One example of this is the modernisation of the Ternitz substation in Neunkirchen in Lower Austria, which was built in 1965. With its reconstruction, the TSO significantly improves the power supply of the industrial district south of Vienna, Upper Styria and the Mürztal valley in north-eastern Styria. In addition, a new phase-shifting transformer (PST) will increase failure safety for all of Austria and facilitate the smart integration of green electricity such as wind power from the Weinviertel region into the APG grid. All in all, the TSO is investing €30m in the substation upgrade.

The Ternitz substation is an important hub in APG’s supraregional power grid. Its infrastructural significance is emphasised by the new 220/110kV transformer, which will be one of three such PSTs in Austria. In the 220kV grid, it regulates the flow of electricity on the power lines in north-south direction and distributes it evenly to assure full electricity supply for the region and for all of Austria. To maintain reliability also during the time of the reconstruction, APG will be keeping the substation in operation with numerous temporary measures. Construction was originally scheduled to be concluded in December 2020, but due to the corona pandemic, completion is expected to be delayed by about three months and is now scheduled for March 2021.

Since mid-April, about 50 APG construction projects that were suspended after the Covid outbreak have been gradually resumed in compliance with the necessary distance and hygiene requirements. APG is thus living up to its responsibility not only towards the energy industry, but also as a driving force for the Austrian economy as a whole. In 2020, the investment volume of all APG construction projects in the areas of grid extension, renovation and maintenance projects will total €350m.
