Upcoming change in the 50Hertz management

05.12.2018

Since 2010, Boris Schucht has been CEO of TSCNET shareholder 50Hertz, one of the four German transmission system operators (TSOs). Before his engagement with 50Hertz, Schucht has already held senior management positions for companies from the energy sector such as Vattenfall Europe Venture GmbH or WEMAG AG. After nine successful years at the helm of 50Hertz, the CEO of the north-eastern German TSO now wants to face new professional challenges.

Boris Schucht and the 50Hertz Supervisory Board as well as the shareholders Elia and KfW (Kreditanstalt für Wiederaufbau) on 4 December consensually agreed that the current CEO will manage 50Hertz up until 28 February 2019. Mr Schucht commented on the recent company evolution: “For 50Hertz, a new era begins after the share transfers this year. After nine very exciting and extremely successful years with a really great team, this is the right time for me to pass on the baton.” Chris Peeters, Chairman of the Supervisory Board, expressed his sincere thanks for Boris Schucht’s “dedicated contribution to the company’s success story”.

ACER consultation on Core Capacity Calculation methodology

04.12.2018

Complex issues require precise phrasing. Therefore the new public consultation of the Agency for the Cooperation of Energy Regulators (ACER) is called: “Public Consultation on the amendments of the proposal for common capacity calculation methodology for the Core region”. The consultation has opened on 4 December and will be accessible until midnight on Christmas Eve. Invited to participate are all interested stakeholders, including regulatory authorities, nominated electricity market operators (NEMOs) and transmission system operators (TSOs).

What exactly is the objective of the survey? The Capacity Calculation Methodology (CCM) quantifies the electrical capacity that can be offered across borders to the day-ahead and intraday markets. The Core CCM is valid within the Core Capacity Calculation Region (CCR), which comprises Austria, Belgium, Croatia, the Czech Republic, France, Germany, Hungary, Luxembourg, the Netherlands, Poland, Romania, Slovakia and Slovenia. The TSOs from the Core CCR – among them are the twelve TSCNET shareholders 50Hertz, Amprion, APG, ČEPS, ELES, HOPS, MAVIR, PSE, SEPS, TenneT, Transelectrica and TransnetBW – have conceived and proposed amendments to the Core CCM.

The competent regulatory authorities of the Core CCR have not yet approved the TSO proposal and asked ACER to decide on whether the modified Core CCM complies with the European Capacity Allocation and Congestion Management (CACM) Regulation. Interested parties are invited to provide feedback on the consultation questions concerning the relevant aspects of the Core CCM.

WindNODE flexibility platform in trial operation

21.11.2018

The energy transition results in a rapidly growing share of volatile electricity volumes from renewable energy generation. The participants in the energy market are thus faced with new and challenging tasks that go beyond the mere safe operation of electricity grids. Optimum capacity utilisation and maximum use of renewable, weather-dependent energy instead of the throttling of sustainable plants are key requirements of today’s market. The TSCNET shareholder 50Hertz, one of the four German transmission system operators (TSOs), meets the new challenges through the systematic use of flexibility.

A single example from 2017 shows the extent of today’s throttling measures: 641GWh of renewable power generation were throttled in the 50Hertz control area for grid stability reasons. In order to use otherwise lost energy, more than 70 partners from all over East Germany are working on the WindNODE project promoted by the German Federal Ministry for Economic Affairs and Energy. A central component of the project is the flexibility platform, a digital procurement system that is designed to reduce the throttling of wind turbines in the event of grid bottlenecks. Via the platform, regional generators, consumers and storage operators offer TSOs and distribution system operators (DSOs) flexible use of their facilities. TSOs and DSOs cooperate closely in the project.

The flexibility platform has now gone into test operation after almost two years of developing. The intention is to balance the load distribution of volatile generation quantities and to integrate them optimally into the system. By connecting or disconnecting flexible loads – for example industrial production facilities – the power consumption at appropriate grid nodes is regulated in such a way that bottlenecks and thus the throttling of wind energy are prevented and maximum use of green electricity is facilitated.

Dr. Dirk Biermann, Chief Markets & System Operations Officer at 50Hertz, emphasises the importance of both, more efficient use of the existing grid and grid extension, to achieve the German government’s renewable share targets. “We need to get into Power-to-X applications and the systematic use of flexibility. This is why the WindNODE platform comes at the right time and can help to effectively use regeneratively generated ‘excess electricity’ instead of throttling it.”

Successful test for the Combined Grid Solution

09.11.2018

The Combined Grid Solution is a joint offshore connection project by the two TSCNET shareholders 50Hertz, one of the four German Transmission System Operators (TSOs), and the Danish TSO Energinet. The binational interconnector in the Baltic Sea will integrate the electricity systems of Denmark and Germany by linking the German wind farm Baltic 2 to the Danish wind farm Kriegers Flak. The utilisation of grid connections from offshore wind farms to couple the transmission grids of two countries is nothing less than a world premiere.

The laying of the two submarine cables “150kV-line KFE-BaZ 155“ and “150kV-line KFE-BaZ 156“ was completed at the beginning of July and the two TSOs have now successfully conducted 24-hour testing of both cables. Around noon on 6 November and in the afternoon thereafter, the two cables were energised one after the other up to the disconnector on the offshore substation OSS KFE and now are ready to transport electricity. Sebastian Wagner, Sub-Project Manager Sea cables at 50Hertz, and Energinet’s Project Manager Daniel Johan Brøndum jointly declared: “Everyone in the team worked closely together and delivered to-the-point. We are very happy and celebrate this success together.”

German TSOs revise grid design principles

29.10.2018

The four German transmission system operators (TSOs) and TSCNET shareholders 50Hertz, Amprion, Tennet, and TransnetBW have revised their plans for grid development in Germany and presented the new version of the “Principles for the Design of the German Transmission System”. This joint document of the four TSOs determines needs-based perspective concepts for secure and efficient grid operation in accordance with national and European legal frameworks and obligations.

With the first publication of the principles in 2012, the German TSOs presented the technical and economic basis of grid design in a transparent and comprehensible manner based on three equally important aspects: grid optimisation, reinforcement and expansion. Since then, the framework conditions have changed in several respects. The TSOs have therefore fundamentally revised and extended the common planning principles last published in the April 2015 version. The principles remain subject to continuous future review by the TSOs and will be adjusted if necessary.

“Siglinde” brings record feed-in

25.10.2018

This week, the windstorm “Siglinde” has not only put the north of Germany to the test, but has also brought TSCNET shareholder 50Hertz, one of the four German transmission system operators (TSOs), a record feed-in of wind power as well as important insights. For the first time, 50Hertz has integrated more than 15,000MW of wind power securely into the grid, 15,382MW to be precise. This new record is roughly equivalent to the output of 15 large conventional power plant units.

However, this welcome development is accompanied by a downer: The transmission system under the responsibility of 50Hertz is reaching its limits and during the “Siglinde” storm, the TSO had to resort to redispatch measures and at times had more than 3,000MW of power output throttled and simultaneously increased in other grid areas. “We are now reaching dimensions that take network control with its current means to its limits,” explains Dr. Dirk Biermann, Chief Markets & System Operations Officer at 50Hertz.

Without the “Südwest-Kuppelleitung”, a 380kV line from the German federal state of Saxony-Anhalt via Thuringia to Bavaria (also known as “Thuringian Power Bridge”), which went into full operation in September 2017, the demand for redispatch would have been higher. Dr. Biermann comments: “Despite this additional transmission capacity and the massive interventions, all our lines to the south of Germany were operating at very high capacity.” This clearly illustrates that grid extension continues to lag behind the expansion of renewable energies. “We need additional instruments for safe system operation ‒ both in the grid as well as in the market,” appeals Dr. Biermann.

First partial feed-in from Arkona wind farm

10.10.2018

The Arkona offshore project in the south-eastern part of the “Westlich Adlergrund” wind farm cluster in the Baltic Sea near the German Island of Rügen is in the final stage of construction. In April 2018, the platform topside for the Arkona windfarm was mounted on the platform jackets. In the following months, the topside was further equipped, tested and prepared for operation. Also the corresponding grid connection, Ostwind 1, has made great progress and has now been partially implemented by TSCNET shareholder 50Hertz, one of the four German transmission system operators (TSOs).

After its completion, Ostwind 1 will transmit the converted electricity from the wind turbines via a 220kV submarine cable to the Lubmin onshore transformer station in Mecklenburg-Western Pomerania. With the realisation of the first partial feed from Arkona during the construction phase of Ostwind 1, the development of the entire connection project is fully on schedule. Currently, 50Hertz is carrying out the remaining work along the cable route to the Arkona platform by laying another submarine cable.

Acer decision on fallback procedures for Core CCR

09.10.2018

In March 2018, the Agency for the Cooperation of Energy Regulators (ACER) was asked by the competent regulatory authorities to decide on the amended proposal of the transmission system operators (TSOs) from the Core Capacity Calculation Region (CCR) regarding the Core CCR fallback procedures. In the following August, ACER invited all interested stakeholders to share their views on the issue in a public consultation. After evaluating the survey, ACER has now published its decision on revisions to the methodology for fallback procedures.

The Core CCR consists of sixteen Central European TSOs, twelve of which are TSCNET shareholders: APG (Austria), ČEPS (Czechia), ELES (Slovenia), HOPS (Croatia), MAVIR (Hungary), PSE (Poland), SEPS (Slovakia), Transelectrica (Romania), the Dutch-German TSO TenneT, and the three further TSOs from Germany 50Hertz, Amprion, and TransnetBW. ACER’s decision introduces minimal changes to fallback procedures in order to improve legal clarity and enforceability. Most importantly, instead of five different shadow allocation rules, only a single set of rules is adopted by the Agency, which specifies in its decision to which bidding zone borders these rules apply.

Congestion management on Austro-German border

10.09.2018

Congestion management will be introduced on the border between Austria and Germany on 1 October 2018. This go-live date was approved by the competent regulatory authorities at the beginning of September and has now been confirmed by all responsible decision-making bodies of the Nominated Electricity Market Operators (NEMOs) and the affected transmission system operators (TSOs), which are all shareholders of TSCNET: APG from Austria and the four German TSOs 50Hertz, Amprion, TenneT, and TransnetBW.

Electricity exchange between Austria and Germany has increased in recent years. In order to ensure safe operation of transmission systems in Austria, Germany and neighbouring countries, and to reduce congestion management costs, the Agency for the Cooperation of Energy Regulators (ACER) included the introduction of a bidding zone split between Austria and Germany in the new design of the European Capacity Calculation Regions (CCRs). Following successful testing of the systems, the operational procedures as well as the scheduling and nomination processes, the TSOs concerned now will implement this decision.

XBID is running stable

07.09.2018

The successful launch of the European Cross-Border Intraday (XBID) solution and ten XBID related Local Implementation Projects (LIPs) in June 2018 has marked a significant step towards the creation of a single integrated continent-wide intraday market. The aim of the XBID initiative is increasing the overall efficiency of cross-border trading and intraday coupling, which both are key components of the future European internal energy market.

The XBID solution has been running now for over two and a half months without any major incidents, delivering continuous trading of electricity across Austria, Belgium, Denmark, Estonia, Finland, France, Germany, Latvia, Lithuania, Norway, The Netherlands, Portugal, Spain, and Sweden. Many other European countries are to follow in a second XBID-wave in 2019. Up to now, the number of trades in XBID has exceeded 2.5m. As a result of this satisfactory commissioning, the Steering Committee, in consultation with the Nominated Electricity Market Operators (NEMOs) and Transmission System Operators (TSOs) involved, decided to shut down the rollback systems.

Among the TSOs collaborating in XBID are the TSCNET shareholders 50Hertz, Amprion, APG, Energinet, TenneT, and TransnetBW, as well as TSCNET client Creos from Luxembourg. Together they have developed a common IT system including one shared order book, a capacity management module, and a shipping module. XBID makes it possible to bring together bids of market participants from different market areas within the region covered by the project, provided there is sufficient cross-border transmission capacity. It thus bundles the whole European intraday continuous market and complements the existing day ahead market.

The XBID solution for a single integrated European cross-border intraday market is running stable and availability of rollback systems has ceased
