Amprion presents CWE market report

03.06.2019

Amprion, one of the four German transmission system operators (TSOs), has published its market report for the period 2015 to 2018. In this comprehensive document, the TSCNET shareholder investigates the development of the electricity market in the Central Western Europe (CWE) region using data from Flow-Based Market Coupling (FBMC). The CWE countries (Austria, Belgium, France, Germany, Luxembourg, and the Netherlands) implemented FBMC in May 2015, which allows TSOs to allocate cross-border capacity and maximise market efficiency without compromising grid stability. This is due to the inclusion of the entire regional network in the coupling of electricity markets.

The control area of Amprion is a central hub for cross-border electricity trading in the CWE region. With its transmission capacities, the TSO can export up to eight GW of electricity at peak times and thus generate more than half of Germany’s total export performance. Transmission via the Amprion grid thus also supports security of supply in neighbouring countries, especially in critical situations such as winter 2016/2017.

Amprion’s analysis shows that the integration of the CWE markets is already well advanced and continues to progress. At the same time, the growing difference between positive and negative price peaks on the electricity exchanges also highlights the challenge of the highly volatile supply of renewable energies. Dr. Hans-Jürgen Brick, Chief Commercial Officer and CFO of Amprion, comments: “The mutual dependency in Europe on system security will continue to rise. We are therefore doing everything physically possible to connect the national markets and networks even better.”

Swissgrid analyses critical situation

27.05.2019

On the critical situation in the Swiss transmission grid on Monday, 20 May 2019, when individual grid elements were considerably overloaded or threatened to be overloaded, TSCNET shareholder Swissgrid, the Swiss transmission grid operator (TSO), has already completed an initial analysis. On that day, with a high Swiss domestic electricity production of around 12 GW, a total of around 4.5 GW was exported, most of it to Germany. Since the load flows typically run in the opposite direction, this atypical situation led to security breaches in the grid.

For reasons unknown, the European grid forecasts did not anticipate that export volumes would increase in the short term from Sunday to Monday. Swissgrid had thus to resolve the grid security breaches in real-time operation in cooperation with colleagues from the European TSOs. This incident shows that the forecasts can deviate considerably from the actual load flows. It also indicates the crucial importance of integrating all transmission grids in Europe, including Switzerland, into the grid modelling, so that any threats to grid security can be identified in advance and coordinated measures can be taken.

However, since Switzerland is excluded from market coupling due to the lack of an electricity agreement with the EU, the deviations between forecasts and effective load flows are likely to increase. An agreement, on the other hand, would include Swissgrid in the models for load flow calculation and capacity allocation of the European partners and provide the TSO with better information on the load flows through Switzerland.

Pylon repair started at Albula Pass

25.05.2019

The windstorm Adrian (Vaia in the German-speaking area) was one of the most devastating storms of the European storm season 2018-19, mainly affecting the northern Mediterranean and Alpine regions. It not only damaged the Venetian Basilica of San Marco and flooded 75% of Venice, but also destroyed transmission lines at the Albula Pass: In the night to 30 October 2018, four pylons from TSCNET shareholder Swissgrid, the Swiss transmission system operator (TSO) bent or collapsed at the high mountain pass in the Canton of Grisons.

Since then, the two affected 380kV lines (Filisur-Robbia and Pradella-Robbia-Sils) have been out of operation, as Swissgrid has decided for safety reasons not to erect a provisional connection with emergency masts in winter due to the danger of avalanches. Nevertheless, grid security in the transmission grid is ensured at all times and there have been no supply interruptions. While security and supply are guaranteed, however, transit capacity to Italy had to be reduced until the line is restored.

Swissgrid began repairing the 380kV lines in mid-April and is now replacing the four broken pylons whose foundations are currently being reconstructed. New pylons and the conductor ropes will then be installed. If everything goes according to plan, the two lines will go operational again at the end of July.

APG automates emergency messages

20.02.2019

“In emergencies involving high voltages, quick help from proper specialists is needed,” explains Stevica Rakic, Project Manager at TSCNET shareholder APG, the Austrian transmission system operator (TSO). As the emergency services need accurate information, all 12,000 pylons in the APG control area have been equipped with an individual QR code since summer 2018. A corresponding specially developed smartphone application enables a reliable and quick notification of the right personnel in an emergency.

The QR codes are located on the pylon number plates and can be read with a scanner or simply with the camera from iOS or Android smartphones. If a random passer-by notices a potentially critical incident, he can press “Emergency Message” after scanning the code and the information process begins with automatically forwarding the message containing the relevant information to APG, the police, ambulance services, and the fire department. Besides, the person reporting is connected directly to the APG Security Center by phone.

If professional personnel use the function, APG’s digital security platform opens immediately. Of course, one cannot always rely on the availability of modern technology. Internet connections can be interrupted or there might be no smartphone available. Therefore, the familiar pylon and line numbers, as well as the emergency telephone number, remain on the plates so that an emergency message can still be sent without a smartphone or internet connection.

“The backbone of cross-border trading” at Euroforum Conference

08.12.2018

Euroforum is a prestigious German promoter of first-class conferences, seminars and meetings and a subsidiary of the Handelsblatt Media Group, which publishes the leading German-language business newspaper. The Euroforum events bring together experts from business, science and politics and create forums for the transfer of knowledge and the exchange of opinions. This year’s Euroforum conference on 6 and 7 December in Düsseldorf, the state capital of North Rhine-Westphalia, was dedicated to the topic of “Intraday trading in the electricity sector – digitisation and automation as growth drivers”.

TSCNET Services as one of the five European Regional Security Coordinators (RSCs) – with fifteen transmission system operators (TSOs) from eleven central and eastern European countries as shareholders – can offer significant contributions on this area, which is why Maik Neubauer, one of the two Managing Directors of the Munich-based company, gladly accepted the invitation of Euroforum to speak at the conference. Mr. Neubauer, who acted in the past also as Board Member of the European Energy Exchange EEX where he already was part of a task force to work on a concept for a pan-European Intraday Trading system, presented the work of the European RSCs to an audience of experts. He stated that the work of the RSCs – largely unnoticed by the general public – is important to ensure a stable transmission network for their TSO shareholders with regional risk analyses. “Without the 24/7 work of the European TSOs and the RSCs to keep the European grid stable there wouldn’t be a sustainable basis for an efficient energy market on the continent,” Neubauer said.

In the conference many discussions had been around the development of the new European Intraday Trading System XBID that helps traders, generators, but also TSOs, to balance out the grids within the day of delivery.

Dutch recovery facility ready for operation

04.10.2018

Although it is most unlikely that there will ever be a complete power outage in the Netherlands, TSCNET shareholder TenneT, the German-Dutch transmission system operator (TSO), wants to be prepared even for such an unimaginable scenario and thus also fulfil European agreements. For these reasons, a new recovery facility for the high-voltage grid was put into operation at the gas-fired Enecogen power plant in the Rotterdam-Europoort area.

In the event of a total blackout, the Dutch power plants will have to be reactivated, which is exactly the task of the new equipment. Like an enormous starter motor, the system ‒ consisting of an emergency generator and a gas turbine ‒ switches the Rotterdam power station back on. Then the rest of the power supply, be it other large-scale plants, solar or wind farms, is connected back to the grid step by step in order to quickly reactivate the national transmission system.

The Enecogen recovery facility is the third emergency system contracted by TenneT in the Netherlands. With comparable units in the north and centre of the country, the new “starter of the south” now completes the TSO’s emergency and recovery concept for total power failures.

“E&M Powernews”: “Excellent overview of the grid”

27.07.2018

Largely unnoticed by the broad public, five European regional security coordinators (RSCs) are working on what is arguably the most important task for ensuring the security of electricity supply at continental level: a stable and secure transmission system. RSCs analyse critical grid situations from a regional perspective and advise their customers in order to avoid bottlenecks or even blackouts. One of them is TSCNET Services. A detailed background article published by “Energie & Management”, a renowned daily German print and online newspaper for the energy market, portrays the company and presents the special challenges that an RSC has to face every day.

For example, a critical situation occurred in the very cold January 2017. “Even though the redispatch coordination functioned well at that time, the emergence of grid bottlenecks has shown that in the course of the expansion of renewable energies in Europe, we need to identify critical conditions and developments even faster”, explains Maik Neubauer, one of the two managing directors of TSCNET Services. For this reason, TSCNET, in close cooperation with the partner TSOs, has established the “Critical Grid Situation Service” to facilitate communication between the RSC and the TSOs.

Close and seamless communication is crucial for TSCNET Services, because the RSC does not intervene in the transmission network itself, but gives recommendations for action. The final decision, however, lies with the responsible TSO, which can always rely on the validity of the information provided by TSCNET. To ensure this reliability, the specialists at TSCNET monitor the network flows in Central and Eastern Europe. This involves a lot of data: More or less 600,000 data series with a volume in the double-digit gigabyte range yield around 300 prognoses every single day – a “big data company with top advisory expertise”.

Still, the volume of data will continue to increase, especially in view of the implementation of the Common Grid Model (CGM) under the EU network codes. “Today, we still lack some data, especially about the situation at the interfaces to the distribution grids”, states Maik Neubauer. Once the individual grid models of the respective TSOs and the CGM have been established, the additional data also flows into the calculations of TSCNET. This will expand the RSC’s perspective and further optimise system operation. While critical situations affecting only two TSOs can be resolved bilaterally, it becomes more difficult, if several parties are involved. An incident in Poland, for instance, may well affect not only Germany but also the Czech Republic. In such a case, the central coordination provided by TSCNET is essential to anticipate problems or to calculate short-term effects.

Every day at 9:00 pm, TSCNET’s Daily Operational Planning Teleconference (DOPT) with the TSOs’ experts will be held to summarise system occurrences and to coordinate possible compensation measures for the next day. Though everyone involved is quite satisfied with this daily routine, the EU is also pursuing divergent plans. In the context of the European Commission’s “Clean Energy for All Europeans” package, the idea of Regional Operational Centres (ROCs) came into being, which would extend the role of current RSCs by giving them operational responsibility. The TSOs – who would have to hand over competences – are sceptical, and also Maik Neubauer has clear positions in this regard. He points out the complexity of the European power system and the valuable experience of national TSOs. Mr. Neubauer therefore prefers to further improve regional coordination and to leave the operational business to the TSOs: “A Europe-wide centralisation of grid control would be a mammoth project with many risks and unknowns.”

“Energie & Management”, the well-esteemed German trade magazin for the energy market, released an article on the Munich-based RSC TSCNET Services.

“ZfK”: “Big data for a stable grid situation”

13.06.2018

With fourteen transmission system operators (TSOs) from eleven Central and Eastern European countries as shareholders and four additional customers from four other countries, the surveillance area of the Munich-based regional security coordinator (RSC) TSCNET Services lies at the heart of the continent. TSCNET was originally set up as a joint TSO initiative to maintain the operational security of the electricity system. Today, TSCNET’s core responsibilities include coordinated network security analysis, capacity calculations, support in critical network situations, and aggregation of all relevant network data for the partner TSOs.

Despite their essential function within the integrated European transmission system, the work of the RSCs still is not well known to those who are not directly involved in the energy market. A comprehensive insight report published in Germany’s leading professional journal for the municipal energy economy, the “Zeitung für kommunale Wirtschaft” (ZfK), offers a great opportunity to improve TSCNET’s name recognition in this specific economic sector. A journalist from the prestigious press medium had a revealing talk with Maik Neubauer, one of the two Managing Directors of TSCNET Services.

The report is centred around TSCNET’s Daily Operational Planning Teleconference (DOPT) with the TSOs’ experts. In these conferences every day at 9 p.m., TSCNET’s risk analysis is presented every day and the catalogue of possible measures is discussed.

Mr Neubauer emphasises the outstanding role of the RSCs as an early warning system for grid security in the increasingly complex and rapidly changing transnational electricity system. He sees TSCNET well prepared for new tasks, as already now the “pan-European network security analysis is going to be strongly aligned with the other european RSCs”.

“Tagesspiegel Background”: “Most valuable advice”

17.04.2018

Will there be large amounts of wind energy in the coastal regions? Where do bottlenecks might occur? And how should transmission system operators (TSOs) react in order to avoid critical network situations? ‒ Safety analysis and risk management for the pan-European transmission system based on large volumes of data is the core business of the European regional security coordinators (RSCs), one of which is the Munich-based TSCNET Services. Although there are many other tasks ‒ such as calculating generation capacity to keep the grid stable ‒ RSCs only monitor and evaluate the market and grid situation to advise their TSO shareholders, but do not operate the grid themselves.

Maik Neubauer, one of the two managing directors of TSCNET Services, took the opportunity to explain the business of the Munich-based RSC more detailed in a personal portrait and interview in the “Tagesspiegel Background Energy & Climate”, a daily market newsletter for decision-makers from the energy and climate sector. The “Background” is created by specialists from the renowned German daily newspaper “Tagesspiegel”. In addition, Mr Neubauer gives insights into his personal view of the digital and energy-specific future, his motivations and inspirations.

Recently, in the context of the European Commision’s “Clean Energy for All Europeans” package, there has been some discussion about the role of the RSCs and wether they should take over operational responsibility. Regarding this, Mr Neubauer represents clear positions: “In my view, Brussels underestimates how complex the European power grids are and how valuable the long experience of national TSOs is.” Hence, the TSCNET managing director welcomes the prevailing opinion that the RSCs will not have direct control of the network in the near future. Instead, TSCNET Services will streamline its evaluative and advisory functions. This includes grid stabilisation assistance after outages, training of TSO staff and active proposals for necessary compensation measures to improve cross-border coordination, increase safety and, ultimately, save costs.
