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.

The power of data in Gothenburg

27.09.2019

OSIsoft is a well-known manufacturer of application software for real-time data management, called PI System. On the second day of this year’s OSIsoft “PI World” user conference in mid-September in Gothenburg, Sweden’s second biggest city, the focus was on utilities and energy management in particular. One of the speakers on this day was Gábor Bús, Lead Data Visualisation & Analyses in our Service Operations business unit.

The topic of the Hungarian-born was “The Power of a Single Integrated Database”. He drew attention to the great responsibility of the 43 power transmission system operators (TSOs) in Europe. TSCNET Services enables them to bridge the huge differences in the characteristics and processing of their vast amounts of data. Several applications are hosted in different environments and work with different virtual identifiers that refer to the same physical network element, such as power lines or substations. Only the standardisation of the virtual identifiers and their storage in a single integrated data system makes it possible to use them effectively.

On the basis of predefined use cases, the experts at TSCNET have developed a total of 205 analysis templates, 13 notification templates, eight PI Vision displays and two ProcessBook displays to support and raise the efficiency of the operational activities. An early warning system for the Congestion Management service is also constantly being experimented with the help of machine learning and artificial intelligence. Gábor’s presentation and a recording of the speech are available freely.

Central project management and office for SuedLink

24.09.2019

The SuedLink extra-high voltage line is not only the most important individual project of the energy transition in Germany, but also the largest underground cable project in the world: Around 700 kilometers of cable will be laid and around ten billion euros invested. By connecting the windy regions of northern Germany with the consumption centres in the industrially highly developed south, “power highways” such as SuedLink are indispensable for achieving Germany’s and Europe’s climate goals. SuedLink is implemented jointly by the two TSCNET shareholders TenneT, the Dutch-German transmission system operator (TSO), and TransnetBW, the TSO from southwest Germany.

In order to efficiently advance the further approval procedure and the subsequent construction of SuedLink, the two TSOs have commissioned the international technical service company Jacobs as central service provider. The aim is to coordinate and control the various tasks such as planning, approval, obtaining easements and construction under one roof. This makes SuedLink the first major project in Germany in which an external central service provider is involved. TenneT Managing Director Tim Meyerjürgens explains why the two partners decided on a model that has proven itself many times in such large-scale projects on the international market: “The schedule for implementation is challenging. At the same time, the expectations of politics and the public continue to rise. For this very reason, controlling and coordination play such an important role.”

The commissioning of Jacobs is accompanied by the opening of the central SüdLink office in Würzburg, Lower Franconia. Together with the central service provider, TransnetBW and TenneT will initially create 130 jobs there, the number of which will rise to 250 in the course of the project. To better incorporate regional knowledge into the planning process, further decentralised project offices are to follow along the route. Dr. Werner Götz, Chairman of the TransnetBW Executive Board, comments on the development: “By commissioning a central service provider and setting up a joint project facility in Würzburg, we have laid the foundations for the successful implementation of this major project.” The staff in Würzburg will include engineers, archaeologists, landscape planners, biologists, geologists, and project managers, all joining forces for Europe’s energy future.

Danish wind power generation exceeds demand

23.09.2019

Sunday, 15 September 2019, now is a historical date for the Danish electricity market. Within the 24 hours of that day and during the first strong autumn winds of the year, wind power generation covered 130 percent of national demand, thus exceeding it for the first time for an entire day. According to preliminary figures from TSCNET shareholder Energinet, the Danish power transmission system operator (TSO), Danish wind turbines generated between 2 a.m. and 3 a.m. early Sunday morning an impressive 60 percent more electricity than the Danish market actually consumed.

For one thing, this beats the previous record of 9 June 2019 (52 percent above demand), but what is even more significant for the Danish energy transition is this being the first 24-hour period ever in which surplus wind energy has been generated during all day and night hours. This surplus wind energy was further transmitted by Energinet and sold to other countries.

Carsten Vittrup, Energy Strategy Adviser at Energinet, comments on these groundbreaking figures: “A mere ten years ago, wind accounted for only about one fifth of our supply. But things have developed extremely fast, meaning that we now see not just hours, but entire days of wind turbines generating more electricity than we need.”

50 new pylons for the Pradella-La Punt line

19.09.2019

The extra-high voltage line in the Swiss Engadine between Pradella/Scuol and La Punt represents a bottleneck in the Swiss and the European transmission grid. To remedy this shortcoming, TSCNET shareholder Swissgrid, the Swiss transmission system operator (TSO), began upgrading the 380kV line to 2 x 380kV in October 2017. This will increase import capacity from the north, strengthen interconnections with Austria and Italy and facilitate the transport of hydropower in the canton of Grisons. The project also improves security of supply in Switzerland and is part of the “Strategic Grid 2025”, Swissgrid’s ambitious modernisation and expansion plan.

Basically, the upgrade means that Swissgrid will attach a second 380kV line to the pylons, which are originally fitted with only one line on one side. Over the past two years, the TSO has reinforced the mast foundations between Pradella and La Punt and will complete this work in autumn. But Swissgrid has also examined the static of the pylons and discovered that some of them have insufficient load capacity for the second circuit. For safety reasons, it was thus decided to replace 50 of altogether 127 masts instead of reinforcing them. This change has no impact on the routing, but on the schedule: The commissioning of the upgraded line will be delayed by at least one year and is now planned for 2022.

Reconstruction start at TransnetBW substation

18.09.2019

On September 18, TSCNET shareholder TransnetBW, one of the four German transmission system operators (TSOs), started the conversion of its substation in Schwörstadt with a symbolic cut of the spade. The construction site is located in the furthest southwest of the German federal state of Baden-Württemberg near the Swiss border. The upgrade provides the technical basis for connecting the substation to the 380kV extra-high voltage grid.

Dr. Werner Götz, Chairman of the TransnetBW Executive Board, referred at the groundbreaking ceremony to the steadily increasing share of renewables in the electricity mix, which confronts TSOs with maintaining voltage at a stable level despite the changing wind and weather conditions. “We are preparing the substation for the requirements of the energy transition and thus are also strengthening supply security in the Upper Rhine region.”

The reconstruction of the substation’s switchgear will be carried out in two stages, starting with the dismantling of the operations building and the switch panels of the existing 220kV switchgear. By 2021, the new 380kV switchgear will have been installed. The new device will initially be operated at 220kV before being connected to the 380kV grid in 2023. This implies that at the same time and section by section, the corresponding power lines will also be upgraded to 380kV.

ČEPS half-year report: Profits support infrastructure

16.09.2019

In 2019, the Czech transmission system operator (TSO) ČEPS continues its extensive infrastructure investment programme to ensure that the development of the Czech transmission system meets the increasing demands of the rapidly changing energy sector. The profits now presented in the company’s half-year report facilitate these efforts considerably.

The TSCNET shareholder concluded the first half of 2019 with a pre-tax profit of CZK 2.3bn (about €88.84m) and a total revenue of CZK 11,903bn (about €460m), an increase of CZK 1,54bn in comparison to the same period in 2018. “Cross-border auctions account for 38% of revenues,” explains Martin Durčák, Chairman of the Board of Directors of ČEPS. As far as the TSO core business is concerned, a total of 32,760GWh was transferred in the first half of 2019.

An important infrastructure project completed in July 2019 is the connection of the Řeporyje-Prosenice line to the Mírovka substation. The branching of this almost 300km long line, which connects the periphery of Prague with the Olomouc region in the east of the country, will increase the safety and reliability of the Czech transmission grid. Other significant investment measures already implemented this year include the construction of the new Přeštice-Vítkov line linking the Plzeň to the Moravian-Silesian Region. In Vítkov, a new 420kV substation with a gas-insulated switchgear was installed to complement the new line construction.

Environmental protection award for TSCNET employee

11.09.2019

Great honour for Diana Carolina Yule Burbano: The Junior Operations Manager in our Service Operations business unit was awarded the Environmental Protection Pin of the Fördergesellschaft der Schleswig-Holsteinischen Wirtschaft (Business Development Corporation of the German Federal State of Schleswig-Holstein) for “Efforts to Protect the Environment and Climate”.

As a graduate of the “Energy and Environmental Management” (EEM) course at the European University in Flensburg in northern Germany, the Colombian-born student cooperated with Schleswig-Holstein Netz AG, a power and gas network operator in Schleswig-Holstein and northern Lower Saxony, as part of her master’s thesis. The young scientist investigated which vehicle types of the company’s own fleet are suitable for conversion to electromobility and developed her own model for estimating consumption and thus for calculating the range, taking into account factors such as load, outside temperature and traffic situation. The annual award was presented in the castle of the state capital Kiel.

Diana has been working for TSCNET Services since autumn 2018. We all congratulate her on this great award.

Final Conference of FutureFlow

10.09.2019

The FutureFlow project reaches the final straight: On 15 October, the Slovenian transmission system operator (TSO) ELES will host the final conference of the successful project in the Austrian capital of Vienna. FutureFlow was launched in 2016 and funded by the EU under the Horizon 2020 programme. The twelve project partners from eight European countries will officially conclude the project in December 2019.

The increasing regenerative energy generation and decreasing flexibility from conventional power plants require innovative approaches by the players in the electricity market. This is where the FutureFlow project comes in by exploring innovative e-trading solutions for smart cross-border balancing and redispatching in the control areas of four central-south European TSOs, all shareholders of TSCNET. In addition to the project coordinator ELES, the other TSO participants are APG from Austria, MAVIR from Hungary and Transelectrica from Romania.

At the final conference the FutureFlow partners will present the most important project results and options for their implementation. These include, for example, the real-time results of the cross-border pilot tests and the operation of the IT platforms developed as part of FutureFlow.
