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.

Flow-Based Market Coupling in the Core CCR is ready for implementation

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.

DA/RE enters pilot phase

02.04.2019

Following its launch in June 2018, the Baden-Württemberg grid security initiative “DA/RE” (“DAta exchange/REdispatch”) has entered the pilot phase on 1 April. The DA/RE initiators are TSCNET shareholder TransnetBW, the German transmission system operator (TSO) from the state of Baden-Württemberg, and the southwest German distribution system operator (DSO) Netze BW with the support of the State Ministry of the Environment, Climate Protection and the Energy Sector. Meanwhile, several grid and facility operators are involved and actively participating in the pilot phase.

DA/RE responds to the increasing volatility and decentralisation of power generation. By utilising the flexibility potential of decentralised plants from lower grid levels, the entire electricity system is intended to be stabilised. Basically, DA/RE is an IT platform, through which grid operators can obtain information on flexibility potentials and coordinatedly retrieve them. In the trial phase, scheduled to last until the end of September 2019, two essential modules for data exchange and coordination between grid and facility operators are to be tested.

With its wide range of decentralised systems, DA/RE adequately represents the current market for flexibility. “Together we can thus test the processes with different DSOs up to medium voltage level and provide the further course of the project with valuable experience,” explains Florian Gutekunst, DA/RE project manager at TransnetBW.

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.

Chairman of the Supervisory Board confirmed

08.01.2019

Dr. Rainer Pflaum, CFO of TransnetBW, one of the four German power transmission system operators (TSOs), has been confirmed as Chairman of the Supervisory Board of TSCNET Services. Dr. Pflaum was elected Chairman for the first time at the beginning of 2016 and now confirmed for the coming three years.

Due to the ongoing implementation phase of security coordination and capacity calculation services for several European regions and new requirements from the Clean Energy Package recently published by the European Commission, TSCNET Services is facing growing challenges and increased needs of close cooperation links to other RSCs in Europe. With the re-election of Dr. Pflaum, the shareholders of TSCNET Services therefore ensure competence and continuity in the Supervisory Board of the company with today 15 TSOs from twelve European countries as shareholders.
