TSOs introduce possible SuedLink routings

21.02.2019

The SuedLink extra-high voltage line is an integral part of Germany’s future low-carbon energy infrastructure. Major supra-regional projects such as Suedlink are included in the German Federal Requirements Plan Act and are often referred to as “power highways”. In order to reach Germany’s and Europe’s climate goals, they are indispensable to link the windy regions of northern Germany with the consumption centres in the industrially highly developed south. SuedLink is jointly carried out by the two TSCNET shareholders TenneT, the Dutch-German transmission system operator (TSO), and TransnetBW, the TSO from southwest Germany.

The European “Project of Common Interest” (PCI) with an investment volume of around €10bn is planned as a DC underground cable. It comprises two measures with a capacity of 2GW each, from the northernmost federal state of Schleswig-Holstein through western Lower Saxony, northern Hesse and southern Thuringia to Bavaria and Baden-Württemberg respectively. In 2017, TenneT and TransnetBW defined a whole network of possible corridor sections suitable for detailed consideration. On that basis, the Federal Network Agency (Bundesnetzagentur) decided on the cable routes to be thoroughly analysed. In recent months, TenneT and TransnetBW then carried out an in-depth examination and evaluation of these corridor alternatives by applying around 150 criteria.

On 21 February, the two TSOs presented the proposed corridor and the other corridor options derived from their study to the Network Agency. “With the detailed studies of the possible corridor variants, we have now identified a specific underground cable corridor that has the smallest possible impact on humans and nature,” explains Manon van Beek, CEO at TenneT. To give all interested parties the opportunity to inform themselves in advance, TenneT and TransnetBW publish the overview maps of the proposed corridor and the grid of all possible corridors on their respective project websites. Numerous dialogue events are to follow. “Transparency is one of our highest priorities,” comments Dr. Werner Götz, CEO at TransnetBW, on this procedure.

Line upgrade in Southwest Germany in planning phase

18.02.2019

The transmission capacity of the extra-high voltage grid in the southwest of the German federal state of Baden-Württemberg must be increased in order to ensure regional security of supply as well as reliable electricity transport in the future. Among the measures taken by TSCNET shareholder TransnetBW, one of the four German transmission system operators (TSOs), is the replacement of the 220kV line between Daxlanden and Eichstetten am Kaiserstuhl by a 380kV line.

This line upgrade is included in the German National Grid Development Plan for electricity and comprises the construction of some 120km of new lines and five substations. The entire project is divided into four sections. The planning approval for the section between Weier and Meißenheim has now been applied for at the competent regional council. After official review, public display and consultation, the line corridor will be determined, followed by the specification of the exact routing in the subsequent planning approval procedure.

EU invests in priority energy infrastructure

05.02.2019

The “Connecting Europe Facility” (CEF) programme by the European Commission (EC) is a major European funding instrument to support the Energy Union, which is one of the EC’s policy priorities. CEF promotes the development of high performing, sustainable and efficiently interconnected trans-European networks in transport, energy and digital services sectors. Significant infrastructure projects of TSCNET shareholders are also considered as Projects of Common Interest (PCIs) and worthy of support.

PCIs financed by CEF include for example the Viking Link interconnector of the Danish transmission system operator (TSO) Energinet, the SuedLink DC line in Germany – a joint venture of the Dutch-German TSO TenneT and TransnetBW from southwestern Germany – and the joint smart grid project SINCRO.GRID of TSOs ELES and HOPS from Slovenia and Croatia respectively.

Last week, the EU Member States endorsed the EC’s proposal to invest a further €800 million under the CEF in infrastructure projects with high cross-border benefits. The current approval concerns the CEF’s financial support for studies and work on a total of 14 projects. Priority has been given to initiatives to increase competitiveness, improve security of energy supply and contribute to sustainable development and environmental protection.

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.

Approval for construction of SuedLink converter

15.01.2019

The substation in Leingarten, operated by TSCNET shareholder TransnetBW, one of the four German transmission system operators (TSOs), is the southwest German ending point and the location for the converter of the SuedLink extra-high voltage line. This supra-regional project is carried out jointly by TransnetBW and further TSCNET shareholder TenneT, the Dutch-German TSO. SuedLink will be of great benefit to Germany’s future energy system as it will transmit sustainable electricity from the north of the country to Bavaria and Baden-Württemberg in the industrially highly developed south.

On 15 January 2019, TransnetBW received the first partial construction permit from the competent district administration for the construction of the SuedLink converter at Leingarten. The first preparatory construction measures can now begin as planned in 2020, and the commissioning of the entire DC underground cable connection with a length of approximately 700km remains scheduled for 2025.

The new equipment in Leingarten will convert the DC into AC so that it can be fed into the transport network. Dr. Werner Götz, CEO at TransnetBW, comments: “With the district administration’s approval for the converter on the site of our substation, we were able to find the best solution for the region and the local community. I am very pleased that we are the first TSO in Germany to receive approval for such a DC converter.”

TenneT to build compensatory gas power plant

10.01.2019

The successive shutdown of nuclear or emission-intensive large-scale power plants is an integral part of the energy transition in Germany. In order not to compromise the national energy supply security, the German legislator provides for special grid facilities that should not serve the market constantly but be available as a “safety buffer” on short notice and at any time when the power system reliability is at risk. TSCNET shareholder TenneT is facing up to this task of the energy future and plans to commission such a special grid facility in the form of a 300MW gas power plant on the site of the Irsching substation near Ingolstadt in the German state of Bavaria.

The Dutch-German transmission system operator (TSO) now has awarded the contract for the construction and operation of the plant to the energy company Uniper. Probably from 1 October 2022, the power plant will be on stand-by to serve as a “safety cushion” by supplying power in emergency cases. The new gas power plant can be immediately activated in order to maintain transmission system safety and the current level of reliability of the electricity supply also in the future.

From the end of June 2018, TenneT, together with the German TSOs Amprion and TransnetBW, has put out to tender a total of 1,200MW of capacity for special grid facilities Europe-wide and non-technology-specific. The tender covers four regions in southern Germany, each with a capacity of 300MW. For one of these regions, in this case southern Bavaria, TenneT has now awarded the first special grid facility contract.

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.

IE2S for smart system consulting

23.11.2018

Whole new challenges for the participants in the energy market arise in the context of intelligent networks, intelligent markets and intelligent products as well as their cross-sector and digital networking in a “Smart System”. TransnetBW, TSCNET shareholder and one of the four German transmission system operators (TSOs), strives to provide targeted advice to those of its customers, whose business models have undergone massive changes as a result of the transition in energy and mobility.

This is why the TSO from the German state of Baden-Württemberg has teamed up with the global consultancy MHP, a Porsche company which specialises in IT and process consulting in the automotive and manufacturing sectors. Under the brand “Intelligent Energy System Services (IE2S)”, TransnetBW and MHP are bundling their core and specialist competencies to develop customised consulting solutions for the energy and mobility market players. While the TSO incorporates the energy industry specific and process-related knowledge as well as the system view into the cooperation, MHP as digitisation and mobility expert has the experience and consulting competence of almost three thousand employees.

With this collaboration, TransnetBW is taking a first step towards strengthening its service business outside the regulatory sector and is also considering industries that have not yet participated in the electricity market but can contribute to grid stabilisation through smart load management at industrial and commercial locations or through the use of storage facilities in electric vehicles. “The energy industry and the automotive industry are moving closer together. There are many new topics that affect both sectors equally. It is therefore a logical consequence to work even more closely together,” explains Dr. Rainer Pflaum, Member of the TransnetBW Executive Board. The competent project manager at TransnetBW, Dr. Dominique Gross, adds: “With IE2S, we want to pursue a new path and bring our expertise in system responsibility and supply security into the context of increasingly digital, decentralised business models.”

TransnetBW pilot on eco-efficient insulating gas

06.11.2018

At its substation in Obermooweiler near the historic city of Wangen im Allgäu and north-east of Lake Constance, TSCNET shareholder TransnetBW, one of the four German transmission system operators (TSOs), is planning nothing less than the world’s first gas-insulated switchgear at extra-high voltage level employing alternative and climate-friendly gas technology. The objective is to apply for the first time in practice an innovative type of insulating gas whose greenhouse effect is more than 99 percent lower than that of the currently used sulfur hexafluoride (SF6) and which is equal to or lower than that of CO2.

There are obvious reasons why SF6 has been the industry standard as insulating gas in high-voltage systems for decades: It has excellent electrical properties, is non-toxic and chemically very stable. However, SF6 suffers from a strong greenhouse effect. For climate protection reasons, TransnetBW is thus looking for eco-efficient alternatives. The TSO’s research project aims to provide new insights into the use of an environmentally friendly alternative gas mixture in gas-insulated 380kV switchgears. TransnetBW’s partner in the project, the engineering company ABB, has experiences in the use of alternative insulating gases for switchgears in distribution grids at lower voltage levels. This expertise will now be jointly transferred to the 380kV level.

“The transmission grid integrates renewable energies and is a key element in implementing the energy transition. We also want to promote new solutions for more climate and environmental protection in the design of our grid infrastructure,” explains Dr. Werner Götz, CEO of TransnetBW. The first preparatory construction measures for the new facility are planned for March 2019. As early as 2021, the new switchgear will be connected in a first implementing step. This means an initial SF6 saving of around 55 percent. In the following second step, the existing installation will be converted. From 2026, the entire system will be SF6-free.
