Golletz appointed interim CEO at 50Hertz

15.02.2019

TSCNET shareholder 50Hertz, one of the four German transmission system operators (TSOs), is continuing its search for a permanent successor to Boris Schucht, CEO of the TSO, who will resign at the end of February 2019. Meanwhile, the 50Hertz Board of Directors has found a suitable temporary in-house solution and appointed the 50Hertz CTO Dr. Frank Golletz as interim CEO. He will combine his new role with his other duties as CTO.

Dr. Golletz has been a member of the Executive Committee of 50Hertz since 2011. He was previously Head of Assets  / Grid Projects and authorised officer. After his PhD in electrical engineering, he began his professional career at the Dresden Institute for Energy Supply (now DNV-GL) and also held managerial positions for the former German utility company VEAG. Chris Peeters, Chairman of the 50Hertz Board of Directors, expressed his appreciation for having “such a qualified and experienced leader on board to steer 50Hertz through the coming months”. Dr. Golletz commented that he felt honoured by the vote of confidence and thanked Boris Schucht for the “wonderful cooperation during the past nine years”.

Revised Network Development Plan for Germany

04.02.2019

The four German transmission system operators (TSOs) and TSCNET shareholders 50Hertz, Amprion, TenneT and TransnetBW today have published the first draft of the new 2019 version of their “Network Development Plan (NDP) 2030” on their joint NDP website. All the different scenarios of the NDP meet the German official 65 percent target for renewables in gross electricity consumption, but differ in terms of the use of innovative technologies, storage technologies and flexibility options. Irrespective of this, a further increase in the internal German electricity market gap can be observed in all scenarios – with cumulative generation in the north and consumption centres in the south and west.

In response to the increase in required transport capacity estimated at around 11GW – due to the expansion of renewables, the significant reduction in the use of coal for electricity generation and the development of the European electricity market – the TSOs consider the construction of two additional major DC lines with a total length of 1160km to be necessary. These two extra lines with a total capacity of 4GW were not part of previous NDPs and go beyond the current German Federal Requirements Plan. The new lines are foreseen to run as underground cables in a corridor from the federal state of Schleswig-Holstein via Lower Saxony and North Rhine-Westphalia to Baden-Württemberg. They are part of the scenario B 230, in which the German TSOs propose to build altogether more than 4500km of new or upgraded power lines by 2030 (the abovementioned 1160km of the new DC lines plus an additional 450km of new constructions and 2900km of upgrades).

The costs for the expansion of the German extra-high voltage grid in the B 230 scenario will rise significantly as a result of the new projects. The TSOs estimate the costs at around €52bn. As in previous years, the Offshore Network Development Plan was drafted together with the NDP and integrated into the new NDP 2030. The NDP publication marks the start of a four-week public consultation. The comments will be taken into account for the second draft of the NEP 2030, which will then be submitted to the Federal Network Agency for review. The Agency is expected to announce its modified plans probably in May, after which the Federal Government will have to confirm the expansion in the official Federal Requirements Plan.

Record wind power feed-in for 50Hertz

16.01.2019

While last weekend’s windstorm “Florenz” with its masses of snow posed great challenges to the European Alpine countries – and thus also to the transmission system operators (TSOs) based there – the north German coasts and low mountain ranges were hit by stormy, sometimes heavy gusts. 50Hertz, the north-eastern German TSO, whose control area includes such geographical ranges, reports a welcome side effect of “Florenz”: a new record in wind energy feed-in.

On 13 January at 8.45 p.m., the TSO’s grid management for the first time recorded more than 16,000MW in the 50Hertz grid. Thus, the very current record level of New Year’s Day 2019 was even surpassed. At that moment on 13 January, the grid area of 50Hertz could theoretically have been completely supplied with wind energy and there still would have been additional export capacities.

“The value has shown us once again that we as a company together with our neighbouring networks and partners are well prepared for such extreme situations. The grid can withstand such loads,” says Andreas John, Head of System Management at 50Hertz. His team at the Transmission Control Centre in Neuenhagen near the German capital of Berlin had the situation well under control any time.

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.
