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.

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.

PtG pilot plants on an industrial scale

29.03.2019

Power-to-Gas (PtG) technologies have the potential to compensate for the weather-related volatility of renewable energies. More specifically, PtG can be used to convert sustainable electricity into gas (green hydrogen or methane), so that the gas infrastructure is additionally available for the transport and storage of electricity from renewable sources. The TSCNET shareholder Amprion, one the four German transmission system operators (TSOs), and TenneT, the Dutch-German TSO, are taking the next important step towards implementing the two most powerful sector coupling projects currently underway in Germany: “hybridge” and “ELEMENT ONE”.

The respective gas transmission partners of Amprion and TenneT are Open Grid Europe for the “hybridge” project and Gasunie and Thyssengas for ELEMENT ONE. Both PTG plants are to convert up to 100MW of electrical power into gas. Their construction is planned at two different sites in the German federal state of Lower Saxony, each close to wind power generation centres and well-developed gas infrastructure.

The grid operators have submitted the necessary investment applications for both projects on 29 March to the Bundesnetzagentur (German Federal Network Agency). If the Agency gives the green light, ELEMENT ONE will be gradually operational by 2022 and hybridge will be fully functional by 2023. Dr. Klaus Kleinekorte, CTO at Amprion, comments on the application, that major PtG projects must now be pushed forward, “if we want to use PtG technology on a large scale in Germany in the 2030s”.

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.

Hybridge to couple energy sectors

11.02.2019

Last summer, TSCNET shareholder Amprion, one the four German transmission system operators (TSOs) for electricity, and Open Grid Europe (OGE), German TSO for natural gas, announced a collaboration in the field of sector coupling by means of power to gas (PtG) facilities. PtG technologies offer promising perspectives for a low-carbon energy future. Now the two partners are ready to launch the sector coupling at system level in Germany with the project “hybridge” comprising an electrolyser in the 100MW class and a hydrogen infrastructure.

At a joint press conference on 11 February in the German capital of Berlin, the current status of hybridge and further steps were presented. Since the partners, who estimate the costs for the entire project at €150m, are ready to enter the approval phase, Dr. Klaus Kleinekorte, CTO at Amprion, explained that the regulatory framework must now be set up quickly. The more so, as it is crucial for the German climate targets that PtG is available in the GW range from 2030. “The ball is in the court of politics. If the course is set now, the plant can already go into operation in 2023,” commented Dr. Kleinekorte.

The ideal location for the first PtG plant in the projected size, in which electricity from renewable energies is converted into green hydrogen and partly further into green methane via an electrolyser, was found at an intersection between the Amprion and OGE grids in the district of Emsland in the northwest of the German federal state of Lower Saxony. The regional natural gas storage facilities, which can be converted to hydrogen in the future, also contribute to optimal conditions for the development of a hydrogen grid to complement the 100MW electrolyser. Amprion and OGE intend to further develop an existing OGE pipeline for the exclusive transport of hydrogen. The concept of Amprion and OGE for sector coupling at system level also includes non-discriminatory third-party access for all market participants to the planned grid coupling infrastructure.

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.

MIGRATE and PROMOTioN workshop in Berlin

22.01.2019

The consortia of two innovative grid-related research projects funded under the EU Horizon 2020 programme – MIGRATE and PROMOTioN – invite to their first joint workshop entitled “Technical challenges and recommendations for the future European power grid”. Both projects aim to maintain security of supply, grid stability and reliability in times of large scale renewable energy integration. The event takes place on 28 February 2019 at the Maritim Hotel near the Brandenburg Gate in the heart of the German capital of Berlin.

The MIGRATE project (“Massive InteGRATion of power Electronic devices”) comprises 23 partners from 13 European countries, including the transmission system operators (TSOs) and TSCNET shareholders Amprion (Germany), ELES (Slovenia), and TenneT (Germany and the Netherlands). The aim of MIGRATE is to explore technology-based solutions for the current and future technological challenges to the transmission system, in particular by linking generation and consumption via power electronics.

The PROMOTioN project (“PROgress on Meshed HVDC Offshore Transmission Networks”) seeks to further develop innovative technologies relevant for the deployment of meshed offshore HVDC grids. Its specific objective is to improve the cooperation between grid operators and major suppliers for a technical architecture and interoperable technologies to accelerate HVDC grid development. As the largest energy project in Horizon, the consortium includes 33 partners from 11 countries, among them TenneT and further TSCNET shareholder Energinet, the Danish TSO.

The first joined workshop of the European research projects MIGRATE and PROMOTioN will be held in Berlin on 28 February

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.

Amprion upgrades historic line

26.11.2018

The power line from Reutlingen-Rommelsbach to Herbertingen in the German state of Baden-Württemberg crosses the southwestern ridge of the Swabian Alb on a length of 61km. Dating back to the 1920s, the overhead line operated by Amprion, one of the four German transmission system operators (TSOs), is an innovative pioneering achievement in the German transmission grid. Already in the Weimar Republic (the German state from 1918 to 1933), it was used to balance electricity between generation and consumption by connecting the Rhenish mining area with water storage facilities in the Alps.

Now it no longer meets the requirements of the energy present and future. TSCNET shareholder Amprion is therefore dismantling the old line and replacing it with new pylons and conductor ropes. Instead of the current 380 and 220kV circuits, the line will in future be equipped with two 380kV circuits. It will then enable an improved exchange of electrical energy between the wind power generation sites in the north, consumers in the residential and industrial areas, and pumped storage plants in the Alps. The line will thus strengthen regional supply as well as supra-regional transmission and is an important component of the energy transition.

A symbolic cut of the spade on 23 November in Zwiefalten-Sonderbuch on the Swabian Alb marked the official opening of Amprion’s currently largest construction site. Over the next two years, 221 old pylons will be dismantled and 181 new ones will be built. The key figures of the construction project are impressive: The TSO is investing a total of around €85m, and over 11,000 tonnes of steel, thousands of tonnes of concrete foundation and around 1500km of aluminium conductor rope will be used along the route. Due to the significance of the Reutlingen-Herbertingen line for industrial history, four old masts will be preserved as industrial monuments.
