Flow-based market coupling ready for Core CCR

18.04.2019

The European Commission Regulation on Capacity Allocation and Congestion Management (CACM) specifies the implementation of Flow-Based Market Coupling (FBMC) for day-ahead electricity trading in the Core Capacity Calculation Region (CCR) comprising Austria, Belgium, Croatia, the Czech Republic, France, Germany, Hungary, Luxembourg, the Netherlands, Poland, Romania, Slovakia and Slovenia. The Core CCR transmission system operators (TSOs) include twelve TSCNET shareholders: 50Hertz, Amprion, APG, ČEPS, ELES, HOPS, MAVIR, PSE, SEPS, TenneT, Transelectrica, and TransnetBW.

The partners of the Core FBMC project are to establish the coupling of all Core CCR borders by means of a Flow-Based Capacity Calculation Methodology (CCM) developed in accordance with the CACM Regulation. The market design for the FBMC implementation has now been finalised and FBMC is currently applied within the Single Day-Ahead Coupling (SDAC) in Central Western Europe (Austria, Belgium, France, Germany, Luxembourg and the Netherlands). The rest of the Core CCR is to follow.

Ostwind 1 in full operation

16.04.2019

Among the four German transmission system operators (TSOs), 50Hertz is mainly responsible for the onshore connection of wind farms in the German Baltic Sea. The Ostwind 1 project of the TSCNET shareholder for connecting the Arkona and Viking wind farms in the “Westlich Adlergrund” cluster in the Baltic Sea near the island of Rügen to the onshore grid has now been finalised – after a construction period of three years and on time for the commissioning of the two wind farms. With a total investment volume of around €1.3bn, the budget was lower than anticipated.

Initial operation of Wikinger took place in autumn 2018, and on 16 April 2019, Arkona was also officially commissioned. Not only is Arkona the largest wind farm in the Baltic Sea, supplying the equivalent of around 400,000 households with electricity, but also its onshore connection sets new standards: Ostwind 1 is the first grid connection in the Baltic Sea with 220kV three-phase current technology to allow a higher transmission capacity. The submarine cables of Ostwind 1 end at the Lubmin onshore substation in Mecklenburg-Western Pomerania, where the current is converted to 380kV and fed into the 50Hertz transmission system.

As Arkona is operated by the German company E.ON in cooperation with the Norwegian company Equinor, the official inauguration ceremony in Sassnitz on the island of Rügen was attended by German Chancellor Angela Merkel and Norwegian Oil and Energy Minister Kjell-Børge Freiberg. On the occasion of the celebration, Dr. Frank Golletz, CEO of 50Hertz, commented on the Ostwind 1 converter platform and the exemplary collaboration during its construction: “This offshore platform has set a new standard. The good European cooperation will also be continued in the operation of the wind farm.”

Second draft of revised German GDP

16.04.2019

In early February of this year, the four German transmission system operators (TSOs) and TSCNET shareholders 50Hertz, Amprion, TenneT, and TransnetBW had submitted the first draft of the new 2019 version of their “Grid Development Plan (GDP) 2030” together with the Offshore GDP to the German Federal Network Agency. Both GDPs were also published for a four-week public consultation. The total of 906 comments and proposals on both GDPs have been incorporated into the second draft of the two GDPs, whenever purposeful and reasonable. This second draft has now been forwarded to the Agency and published on the joint GDP website.

While all the different scenarios of the GDP 2030 meet the official German target of 65 percent for renewable energies in gross electricity consumption, they differ in terms of technologies as well as storage and flexibility options. The TSOs respond in the GDP to the increase in the required transport capacity due to the gap in the German electricity market with the renewable generation mainly in the north and the consumption centres in the south and west. For the second draft of the GDP 2030, the TSOs have taken greater account of the possible German coal exit to ensure that the grid development measures identified in the scenarios are appropriate even in the case of an early and complete phase-out.

In all scenarios for 2030, the transmission capacity of the DC connections amounts to a total of 12GW, while the concrete figures for the need for grid reinforcements (2750 to 2800km) and new construction measures (1600 to 1700km) differ slightly. In the second draft of GDP, the TSOs carried out a cost-benefit analysis for a total of eight interconnectors and a reassessment of system stability. This analysis reveals a considerable need for reactive power compensation systems. As a result, the costs for onshore measures in scenario B 2030 increase from €52bn to €61bn compared to the first draft. The Network Agency will now evaluate the revised draft and adapt its own planning, which then must be confirmed by the Federal Government in the official Federal Requirements Plan.

News from PCI Energy Days

20.03.2019

The PCI Energy Days, organised by the European Commission (EC), offer promoters of European Projects of Common Interest (PCIs) the opportunity to present their projects and exchange experiences on how to build a future-proof and environmentally friendly energy infrastructure with innovative concepts. The inaugural PCI Energy Days took place on 19 and 20 March 2019 in the Belgian capital of Brussels and featured a policy conference as well as an exhibition on the practical implementation of specific PCIs. Among the attendees were the European Network of Transmission System Operators for Electricity (ENTSOE), the three transmission system operators (TSO) and TSCNET shareholders ELES from Slovenia, HOPS from Croatia and the Dutch-German company TenneT.

ELES took the opportunity to present in cooperation with HOPS the Croatian-Slovenian smart grid project SINCRO.GRID. Coordinated by ELES, SINCRO.GRID comprises in addition to the TSOs also two distribution system operators (DSOs) from both countries. The aim of the cross-border project is to optimise the efficiency of the respective national power transmission systems using advanced technologies and innovative data processing methods.

The Renewables Grid Initiative (RGI), an association of non-governmental organisations (NGOs) and TSOs from all over Europe, was also present at the PCI Energy Days to celebrate the signing of the Marine Grid Declaration. The Declaration sets out principles for grid development in the marine environment, such as promoting early mutual communication with stakeholders, adequate protection of the marine environment and knowledge sharing. The RGI members, which include the TSCNET shareholders 50Hertz, Amprion, HOPS, Swissgrid and TenneT, recognise the cooperation between TSO and NGOs as a highly promising approach to building a sustainable marine grid infrastructure. The signatories to the Declaration commit themselves to developing marine projects in accordance with nature conservation principles and early stakeholder involvement. The Marine Grid Declaration builds on the principles previously agreed in RGI’s European Grid Declaration. If you are interested, you can still sign both declarations. In this case, please contact the RGI.

First capacity offers on WindNODE platform

17.03.2019

Today’s energy market, with its ever-increasing share of volatile quantities of electricity from renewable sources, demands optimum capacity utilisation and systematic use of flexibility – already now and even more so in the future. To be well prepared for the challenges ahead, more than 70 partners from all over eastern Germany are working on the WindNODE project, including TSCNET shareholder 50Hertz, the German transmission system operator (TSO) responsible for the region. A core component of WindNODE is the flexibility platform, through which regional producers, consumers, and storage operators offer TSOs and distribution system operators (DSOs) flexible use of their facilities. This is intended to reduce the throttling of wind turbines in the event of grid bottlenecks.

The WindNODE flexibility platform has been in trial operation since November 2018. On 14 March 2019, capacities were offered and called up for the first time. “This means that the trial operation is now entering the practical phase and we can demonstrate that the integration of numerous producers, storage facilities and consumers in one market environment leads to less throttling of renewables – especially now in a very windy season,” explains Georg Meyer-Braune, project manager WindNODE at 50Hertz. The test phase of the platform will last until summer 2019 and processes will be gradually established at further partners, who will thus become potential suppliers. The platform will then be in continuous operation until the end of the project term in 2020. The aim is to use the dedicated facilities for congestion management also after the completion of the WindNODE project.

50Hertz plans to invest some €3.4bn

26.02.2019

Northeast Germany – and thus the control area of TSCNET shareholder 50Hertz, one of the four German transmission system operators (TSOs) – continues to be a pioneer in the integration of renewable energies in Central Europe. For the second year in a row, renewables accounted for more than half of electricity consumption, and once more a new record was set with a regenerative share of 56.5% (2017: 53.4%). The installed capacity of renewables rose to 32.9GW, which is why Boris Schucht, CEO of 50Hertz, had every reason to express his contentment with this development during the 50Hertz balance sheet press conference on 26 February 2019 in the German capital of Berlin: “We are proud that with this record share of renewables, we can contribute to a successful energy transition.” Since this share will increase continuously in the 50Hertz control area, the federal growth target of 65% for 2030 can be achieved as early as 2021.

At the same time, the costs for congestion management, mainly caused by redispatch, fell significantly last year, by an impressive €100m to around €105m. This is due in particular to the effect of the extra-high voltage line “Südwest-Kuppelleitung” (aka “Thuringian Power Bridge”) and two now fully operational phase-shifting transformers (PSTs) on the borders with Poland and the Czech Republic respectively. But also in the future, the expansion of the transmission infrastructure must keep pace with that of the renewables. 50Hertz is taking this into account with exceptionally high investments in the transformation of the energy system. These are facilitated by the TSO’s excellent operating results. Over the past five years, 50Hertz has already invested over €3bn in the grid (€492m in 2018). By 2023, 50Hertz plans to spend a further €3.4bn (€420m in 2019).

Among the outstanding infrastructure projects are the “Ostwind 1” offshore connection, which has been in trial operation since last year, and the “Combined Grid Solution”, a Danish-German interconnector in the Baltic Sea that links the German “Baltic 2” wind farm with the Danish “Kriegers Flak” farm and will be connected to the grid in 2019. The supra-regional DC project “SuedOstLink” is making significant progress, too, as the federal sector planning is underway and the European tender for the underground cables has been launched. 50Hertz CTO Dr. Frank Golletz, who will take over the function of Boris Schucht as interim CEO from 1 March 2019, announced the continuation of the TSO’s ambitious investment program. Golletz also pointed out that the political and regulatory framework must be optimised and made innovation-friendly to realise the energy transition.

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”.
