  • Cooperation agreement concluded on joint electricity hub and extra-high volt-age DC-line
  • Innovative multi-terminal hub planned in Schleswig-Holstein at the North Sea coast
  • Integration of four gigawatts (GW) North Sea offshore wind power
  • Electricity transport via 200 km long underground DC cable
  • Bayreuth/Berlin, 17 January 2022 –Transmission system operators 50Hertz and TenneT are planning  to jointly transport wind power from the North Sea into the German power grid. The two companies have signed a cooperation to realise an innovative multi-terminal hub in the area of Heide (Schleswig-Holstein) and an extra-high voltage direct current link (HVDC) to Mecklenburg-Vorpommern. The project is part of the 2035 grid development plan (2021) confirmed by the Fed-eral Bundesnetzagentur (BNetzA).


    Stefan Kapferer, 50Hertz CEO: "If Germany is to become climate-neutral by 2045, there must be even more focus on cooperation in the future. 50Hertz and TenneT are therefore working together and joining forces to tackle this challenging project in order to transport as much electricity generated at sea as quickly as possible to where it will be urgently needed in the future."


    Tim Meyerjürgens, COO of TenneT: "With the joint implementation of the onshore hub in Schleswig-Holstein, TenneT and 50Hertz are laying the foundation for even higher utilisation of onshore DC lines while at the same time increasing the level of security of supply. In addition, the concept enables to accelerate the expansion of offshore wind energy, as envisaged by the new German government. With the implementation of the onshore hub and the three grid expansion projects linked to it, it will be possible to connect four gigawatts of offshore wind energy from the North Sea in the area of Heide as early as 2032. This means that one part of the project will be completed three years and another even five years earlier than originally planned in the grid development plan."


    The joint project of the two companies consists of several components: In the area of Heide, 50Hertz and TenneT want to build the onshore multi-terminal hub for several direct current connections. It consists of an innovative direct current switchgear. This construction enables the direct and space-saving connection of two offshore direct current connection systems, each with a capacity of two gigawatts, with an onshore direct current link. In addition, a converter is connected to this plant, which converts direct current (DC) into alternating current (AC), which is then available in the region for planned offshore hydrogen electrolysers to decarbonize the industry located there, among other things. The converter can also be used to enable the transport of electricity generated by onshore wind turbines.


    Between this multi-terminal hub and a converter in the area of Klein Rogahn near Schwerin, 50Hertz and TenneT plan to lay a direct-current underground cable around 200 kilometres long that will transmit electricity at the 525 kilovolt (kV) voltage level. 50Hertz will be responsible for the eastern section and TenneT for the western one.


    The two offshore grid connection systems for the area of Heide confirmed in the just published grid development plan (Netzentwicklungsplan 2035 / 2021) will be implemented separately: the NOR-12-2 system will be connected to the multi-terminal-hub by 50Hertz and the NOR-X-3 sys-tem by TenneT.


    Technically, the multi-terminal hub solution is an innovation as up to now, direct current connec-tions at sea and on land have been realised as pure point-to-point connections. In the multi-terminal hub, however, several direct current connections converge. The electricity is fed into the transmission grid via DC or AC lines according to the corresponding transmission capacities and demand situations. Therefore, not three but only one AC/DC converter station has to be built in the Heide area. This reduces costs and land consumption on site – and furthermore helps to make load flows more flexible.

    news-2564 Thu, 13 Jan 2022 09:00:00 +0100 German offshore share of total wind energy yield rises to almost 18 percent in 2021 In the Netherlands, almost twice as much wind energy was produced offshore as onshore https://www.tennet.eu/tinyurl-storage/detail/german-offshore-share-of-total-wind-energy-yield-rises-to-almost-18-percent-in-2021-in-the-netherlan/ North Sea "wind harvest" becomes a stabilising factor in the low-wind year 2021TenneT welcomes plans of the Federal Minister of Economics to prioritise offshore expansion in the future in the German North Sea  
  • North Sea "wind harvest" becomes a stabilising factor in the low-wind year 2021
  • TenneT welcomes plans of the Federal Minister of Economics to prioritise offshore expansion in the future in the German North Sea  
  • In 2021, the transmission system operator TenneT transmitted around 20.3 terawatt hours (TWh)*) of offshore wind energy from the German North Sea to land. In purely arithmetical terms, this can cover the annual demand of more than six million households with green energy. The annual result for 2021 is below a previous year's value for the first time: in 2020 it was still 22.76 TWh. The decline is primarily due to weather conditions, as 2021 was a low-wind year overall. In Germany, total onshore and offshore wind power generation reached 114.37 TWh in 2021 (previous year 129.63 TWh). The share of North Sea electricity rose to 17.8 percent (previous year 17.6 percent).


    TenneT COO Tim Meyerjürgens said: "In Germany, the share of North Sea electricity in total wind power generation now accounts for almost one fifth and is proving to be a stabilising factor in years with weak winds. On average, we generate around twice as many full-load hours offshore as onshore and can thus partially compensate for lulls on land. Recently, however, there has been no increase in offshore wind power. We therefore welcome the plans of Federal Minister of Economics Robert Habeck to give priority to offshore expansion in the future and to strengthen   co-utilisation and cross-border projects in the process.”

    The emergency programme announced by the Federal Minister of Economics could give the energy transition the urgently needed momentum it needs to get back on track and achieve the ambitious climate protection targets, said Tim Meyerjürgens. "The approach of integrated, forward-looking planning of the various grid infrastructures is also correct - because this is the prerequisite for achieving climate neutrality in 2045. For this, we urgently need modern, efficient planning and approval procedures. The goal must be to make planning as fast as construction. There are enough levers to be tightened, for example, standardisation of species protection and closer dovetailing of regional planning and planning approval procedures. At the same time, it is important that the government ensures that we have the necessary political support for implementation on the ground and that we jointly campaign for acceptance," Tim Meyerjürgens stressed. 


    In the Netherlands, the transmission capacity of TenneT's offshore grid connections amounts to 1,503 MW **). These transmitted 4.71 TWh in 2021 (previous year 1.82 TWh). The strong increase compared to the previous year is mainly due to the fact that the commissioning of the Borssele Beta offshore grid connection system only happened in the second half of 2020. A further 3.53 TWh was fed directly into the Dutch TenneT grid onshore by Dutch offshore wind farms in 2021. In total, almost twice as much wind energy was thus produced offshore in the Netherlands as onshore. The total onshore wind energy capacity in the Netherlands is 4,500 MW, which generated 4.41 TWh in 2021.


    The latest increases in climate targets and electricity demand expectations are leading to ever greater technical challenges for TenneT as a transmission system operator. TenneT is facing up to this and is working successfully and at full speed on further grid expansion on land and at sea. TenneT already operates more than half of all offshore grid connections in the EU. By 2030, TenneT will realise 16 more and then provide almost 29 gigawatts of wind power transmission capacity in the North Sea. In the same period, TenneT will invest around 20 billion euros in the Netherlands and Germany for this purpose.       


    Further offshore balance data

    In the German North Sea, the maximum value of the feed-in capacity of offshore wind farms in 2021 was measured on 29 January at 6,357 megawatts (MW).


    The capacity expansion of offshore wind farms in the German North Sea was 6,679 MW on the reporting date of 31 December 2021, with no change from the previous year. TenneT's offshore transmission capacity is 7,132 MW in the German North Sea.


    Wind turbines in the German Baltic Sea (50Hertz grid area) generated 3.7 terawatt hours in 2021 (previous year 4.13 TWh), so that Germany's total offshore generation in this period was 24 terawatt hours (of which North Sea 20.3 TWh).  Adding 90.37 terawatt hours*) of onshore wind energy generated, the total yield in Germany comes to 114.37 terawatt hours*) (previous year 129.63 TWh).

This will also create greater risks for the security of supply for the Netherlands. These are the findings of the report ‘Monitoring Security of Supply 2021’, an annual analysis by TenneT that is commissioned by the Dutch Ministry of Economic Affairs & Climate Policy. In this report, TenneT analyses whether the Netherlands has enough production capacity to meet the national electricity demand in the short, medium, and long term. After 2025, uncertainties increase and security of supply drops. A robust electrification of society, decreasing coal and gas-fired capacity, and increasing production of wind and solar power make the system increasingly dependent on weather conditions and imports.  A further reduction in the capacity of gas and coal-fired power plants will result in a greater interdependence among countries in Northwestern Europe to meet their security of supply requirements in the medium to long term (2025-2030).

A robust electrification of society, decreasing coal and gas-fired capacity, and increasing production of wind and solar power make the system increasingly dependent on weather conditions and imports. 

     

    Conclusions from the report

    • Until 2025, the Netherlands has enough domestic production capacity to meet national electricity demand. With the help of TenneT’s transmission links with other countries, the norm* of a 4-hour annual shortfall in electricity supply compared to demand is not expected to be exceeded, even in extreme scenarios. 
    • After 2025, uncertainties increase and security of supply declines. A robust electrification of society, a decrease in the operating capacity of gas and coal-fired power plants and an increase in sources with variable production will make the system increasingly dependent on weather conditions and imports.
    • Interdependencies between countries are rising. Due to increased dependency, security of supply is no longer a national matter; national decisions have international consequences. 


    “Balance between supply and demand becoming more dynamic”

    In the Netherlands, security of supply is still very high. The availability of the high-voltage grids in the Netherlands was 99.9999% last year, but the energy system and the electricity market are in a state of flux. Maarten Abbenhuis, COO at TenneT: “Climate targets are being fine-tuned in coalition agreements. Ins 2030 coal will no longer be allowed to be used to generate electricity in the Netherlands. The scale of decentralised power generation is increasing rapidly. On the demand side, we are seeing an increase due to the electrification of mobility, for instance, and industry employing more sustainable practices. It is becoming increasingly important that the demand for electricity moves flexibly with the weather-dependent supply. The balance between supply and demand is becoming more dynamic and requires new concepts, like storage. These developments are creating increasing risks for security of supply. Therefore, promoting electrification will have to go hand in hand with measures to boost flexibility and storage on both the supply and demand side. Energy exchange with other countries also needs to be looked at. The interdependence among countries in Northwestern Europe to meet their security of supply in 2030 is as great as ever. In its 2030 forecast, the number of hours the Netherlands depends on supply from other countries has grown from 453 hours in last year’s report to 593 hours in this year’s edition. It is crucial that the Netherlands discusses and aligns its policy with neighbouring countries to continue to guarantee security of supply in the long term. As such, it’s a good development that a similar monitoring exercise is being carried out on a European level, namely the European Resource Adequacy Assessment (ERAA).”


    Developments in the short term

    While the report Monitoring Security of Supply mostly focuses on the medium and long term, there are several short-term developments at play that can affect security of supply. The Dutch cabinet decided at the end of last year that coal-fired power plants could only run at 35% of their capacity from 1 January 2022. In addition, gas supplies will be limited this year.


    Patrick van de Rijt, Head of Market Analysis Energy System Planning at TenneT: “We haven’t been able to include the coal production limitations in our calculations for this report. If this 35% coal production is reached before the end of the year, this decision could have a negative impact on the available capacity in the Netherlands. Within the 35% production limit, owners of coal-fired power plants decide when to apply this. As a result, gas plants will produce more in the coming years and more electricity will most likely be imported.”


    Coalition agreements with bigger ambitions

    Very recent new coalition agreements concluded in both the Netherlands and Germany may have an impact on developments in the energy market. For instance, Germany recently decided to close all coal-fired power plants sooner than planned, in addition to the well-known Kernausstieg, i.e., halting all nuclear power. At the end of last year, the new coalition in Germany announced that coal-fired power plants must close in 2030 instead of 2038. This, too, may have an impact on security of supply. Van de Rijt: “Due to the increased dependency, security of supply is no longer a national matter; national decisions have international consequences”. Together with bigger ambitions for wind and solar, Van de Rijt therefore believes it’s essential that EU countries work closely and transparently together to agree on what capacity should be phased out in the coming years and what sources or capacity should replace it.

     

    * This norm is the expected value of the number of hours per year that available production capacity will not be able to meet demand, i.e., the so-called Loss of Load Expectation (LOLE). A maximum LOLE value is set as a criterium for the adequacy of a system, i.e., the acceptable risk that during a certain number of hours per year demand cannot be met; this value translates unambiguously to the minimum amount of required production capacity. The LOLE average used to assess the Dutch system is 4 hours per year.

The transformer station, also called topside, is one of the two topsides of the Hollandse Kust (zuid) offshore grid, which will connect the offshore wind farm area with the same name to the Dutch onshore high-voltage grid. 

    The offshore transformer station of the Hollandse Kust (zuid) Alpha platform is successfully installed on the jacket in the North Sea, about 20 kilometers off the coast of The Hague, on Sunday December 26th 2021. The transformer station, also called topside, is one of the two topsides of the Hollandse Kust (zuid) offshore grid, which will connect the offshore wind farm area with the same name to the Dutch onshore high-voltage grid. 

    Marco Kuijpers, Director of Large Projects Offshore: "With the installation of the Alpha topside, the offshore grid that TenneT is building in the North Sea is starting to take shape. Hollandse Kust (zuid) Alpha is the first connection of an offshore wind farm to the Maasvlakte, with a capacity of 700 MW. Wind energy plays a crucial role in the energy transition, also in industry, and I am proud that TenneT can contribute to a sustainable future in this way."

    From Dubai to the North Sea

    Over the past year, contractor Petrofac has been working on the fabrication of two High Voltage Alternating Current (HVAC) transformer stations Alpha and Beta at the Drydocks World fabrication yard in Dubai. Mid-November, Mammoet, a specialist in heavy transport and lifting, took care of the weighing and loading of the 3,830-tonne Alpha topside onto the transport vessel Tai An Kou. From Dubai, the Tai An Kou sailed in one month to the Alexiahaven on the Maasvlakte, where it arrived on Tuesday December 21st. 

    Offshore company Allseas carried out the installation

    In the Alexiahaven, the Alpha topside was loaded from the transport vessel onto the multipurpose platform installation and removal vessel Pioneering Spirit of offshore company Allseas, which then sailed to the installation location in the North Sea. After completion of preparatory work, Pioneering Spirit accurately positioned the Alpha topside on the substructure, also known as jacket.

    "It is great to be involved in an energy project of such strategic importance to the Netherlands," said Edward Heerema, President and CEO of Allseas. "Pioneering Spirit has made a name for itself in recent years with pioneering lifts in the oil and gas industry. The successful installation of the Alpha topside demonstrates the versatility of the vessel and our added value in the energy transition."

     

    Significant milestone in the delivery of this important energy transition project

    Sami Iskander, Petrofac Group Chief Executive, adds: “The safe installation of the Alpha topside is a significant milestone in the delivery of this important energy transition project. Everyone involved should be proud of this achievement. Petrofac has been building a successful track record in offshore wind for more than a decade now, which reflects the capability of our engineers and the quality of our delivery. We are collaborating closely with our partners on the upcoming delivery of the Beta topside and successful grid connection.”

    The Beta topside - also with a capacity of 700 MW - is expected to follow in the first quarter of next year. When the wind farm area Hollandse Kust (zuid), developed by wind farm developer Vattenfall, is fully operational in 2023, it will generate an amount of renewably energy that is equivalent to the annual consumption of more than two million households. Hollandse Kust (zuid) is the first subsidy-free wind farm area in the world.

This will offer more possibilities to meet connection requests. These congestion studies will be completed as from Q1 2022. TenneT will anticipate the new Electricity Grid Code in its ongoing congestion management studies. This will offer more possibilities to meet connection requests. These congestion studies will be completed as from Q1 2022.

    Earlier this year TenneT announced a number of new congestion studies for Brabant, Limburg, Friesland, Flevopolder, Gelderland and Utrecht. The rapid growth of sustainable production in particular has created bottlenecks in various regions. The grid manager will then start a study into the possibilities of applying congestion management. Congestion management, in which flexibility plays an important role, allows for better use of the existing grid and creates room for new initiatives. The application of congestion management is a temporary measure on the way to structural grid reinforcements.

    New regulations in development

    New regulations on the application of congestion management are currently being developed. The current rules provide limited scope for applying the market mechanism, do not meet the challenges of the energy transition and are therefore in need of renewal. The outlines of the new rules were published by the regulator ACM in August. The consultation round has closed and the regulator has held a hearing on the views.

    More opportunities based on new code decision

    The new Grid Code will provide more scope for the application of congestion management, allowing more customers to be connected to the grid. Anticipating these changes, TenneT is therefore conducting congestion studies - in anticipation of the final code decision - on the basis of the new rules. In doing so, TenneT is for the time being applying its views on the ACM's draft decision. Once the Code is finalised, TenneT will update its studies as necessary. TenneT expects the studies to be completed as of Q1 2022.

  • TenneT starts tender of 525 kV DC offshore cable system for Dutch IJmuiden Ver projects
  • Market parties and TenneT set new global offshore standard, first connection operational in 2028
  • New transmission standard supports next step

    European countries have recently set new targets to meet climate objectives. The Dutch and German governments want to connect an additional 20 Gigawatt (GW) of offshore wind capacity on top of existing 2030 targets. TenneT, responsible for the Dutch offshore grid and part of the German offshore grid, developed a new 2 GW standard to be able to accelerate offshore wind deployment. Together with market parties, the transmission system operator develops a new High Voltage Direct Current (HVDC) system to connect future wind farms to both offshore and onshore grids. The new transmission standard supports the essential next step towards larger offshore wind farms and a North Sea wide European Hub-and-Spoke system - combining wind power connection, coupling of energy markets through interconnection and smart integration into the main onshore grids. As part of this development, the Dutch IJmuiden Ver projects will be hub ready to connect a future multi-purpose interconnector to the UK. TenneT now takes the next step in the process by opening the tender for the 525 kV DC cable system for the Dutch IJmuiden Ver projects.

    Less spatial and environmental impact

    With this tender, TenneT enters the next phase for the innovative 2 GW projects in the IJmuiden Ver wind area. It is expected that this contract will be awarded by the beginning of 2023. Recently the engineering for the land stations and the platforms was tendered. The first 2 GW IJmuiden Ver connection is planned to be operational in 2028. The 2 GW grid concept results in fewer platforms and land stations, and a bundled cable design. This is not only interesting in financial terms but also ensures that TenneT causes lower emissions and has less spatial and environmental impact.        

    Innovative cooperation TenneT and market parties

    Marco Kuijpers Director Large Projects Offshore at TenneT: "The recently announced increased targets for offshore wind in the North Sea area by the German and Dutch governments underline the importance and necessity of the 2GW Program. The innovative cooperation between TenneT and the  cable suppliers, joint in the ‘prequalification program’ will lead  to a new global market standard. This standard is crucial to reach the worldwide climate ambitions and re-confirms TenneT’s position as the frontrunner in offshore grid development.”

    About the 2GW Program

    To be able to accelerate we set up the 2GW Program for the Netherlands and Germany. In this we combined our extensive know-how in offshore grid development with a unique transnational approach and developed a new offshore standard together with the market. With the 2GW Program we can really unlock the possibilities of the North Sea. So we can provide Europe and its inhabitants with even more green energy in a safe and cost efficient way - all with the least environmental impact possible. With the 2GW Program, we increase the pace and tackle the future of the offshore grid expansion through harmonisation. At least six standardised offshore grid connections with a transmission capacity of 2 GW each will strengthen TenneT's role as driver of the European energy transition in the Dutch and German North Sea until 2030. The 2GW Program sets the new beat of the European energy transition.

TenneT together with other European Transmission System Operators (TSOs) of the Core Capacity Calculation Region (Core CCR) have taken another important step on the backbone of the European Energy Market of the future: The Improved Coordination Solution (ICS) of remedial actions.

    TenneT is part of the biggest capacity calculation region, the so-called Core, existing of 16 TSOs of Austria, Belgium, Croatia, the Czech Republic, France, Germany, Hungary, Luxemburg, the Netherlands, Poland, Romania, Slovakia and Slovenia.

    They are developing and implementing market integration solutions defined in European legislation. Further integration of the wholesale electricity markets is essential for the energy transition towards a carbon free energy system.

    The current regulatory focus is thus on increasing cross-zonal capacities including increased cooperation and harmonisation between member states. Since it becomes increasingly challenging and expensive to maintain operational grid security, a common cross-border determination and coordination of remedial actions is needed. That is why the ROSC (Regional Operational Security Coordination) Methodology were developed and adopted for each European CCR. For each CCR, the methodology establishes common processes for Regional Security Analysis, Remedial Action Optimization, Coordination and Cost Sharing within the respective CCR. The processes cover the operational planning timeframe Day Ahead and Intraday and will complement and replace already existing national and international operational planning processes. The ROSC methodology will be stepwise implemented in the coming years and they bring an international obligation of TSOs to share and coordinate remedial actions for solving congestions in TSO´s grids. It should lead to a more efficient use of remedial actions and to enhancing the security of electricity supply.

    First step of Regional Operation Security Coordination between 13 countries

    As part of this process on 1 November, the ICS process was launched by CCR Core TSOs and Regional Security Coordinators (RSCs). RSCs are centres of cooperation of the involved TSOs and play an important operational role in all the coordinated processes in CCR Core. The ICS provides a daily exchange of Remedial Actions potential, such as Redispatch and Countertrade potential, topological measures, available Phase Shifter Tap ranges and also introduces a common Coordination process for the planning and activation of these Remedial Actions.

    Target solution will be implemented as next step in 2024

    The implementation of the ICS marks an important milestone, but only the first step in a sequence of implementations which TSOs will perform in order to fulfil the guidelines on electricity transmission system operation established by the EU Commission (SO GL). With this early implementation the existing operative planning processes are prepared for the target solution of the future, the Coordinated Security Analysis (CSA). For the target solution a common centralized platform will enable Core TSOs to optimize remedial actions, in order to relieve existing congestions in the grid and utilize the grid in the most efficient way.

  • Battery storage helps to stabilize the electricity system by providing system services
  • Intelligent interaction of battery storage systems to support congestion management in the transmission Network
  • Bayreuth/Oldenburg, 10 November 2021. Transmission system operator TenneT and EWE subsidiary be.storaged GmbH, which specializes in services relating to the construction and operation of battery storage systems, are collaborating on a pilot project that will test support for congestion management in the transmission network through the intelligent interaction of decentralised battery storage systems.
    To do this, be.storaged will bundle the flexibility potential of different battery storage systems via an agent-based energy management system and transfer it to the aggregated flexibility potential in the event of bottlenecks in the power grid. This will not only increase the economic value of the battery storage systems participating in the pilot project, but also allow them to contribute to a successful energy transition.

    Agent-based energy management system increases the flexibility potential of battery storage systems for congestion management

    Until now, battery storage systems have primarily been used in a so-called ‘single-use operation’, e.g., to increase the consumption of photovoltaic electricity among household customers or to limit load peaks for commercial customers. However, the existing flexibility potential for the various uses in the electricity and system service markets remains mostly unused. As such, be.storaged has developed an agent-based decentralised energy management system with the Oldenburg OFFIS Institute for Computer Science, which enables a ‘multi-purpose operation’ of battery storage.
    In the pilot project with TenneT, local agents connect the individual battery storage systems to form a swarm and the pooled flexibility potential that is still available is transported from be.storaged to TenneT via the Equigy Crowd Balancing Platform. Depending on the respective load flow situation, this enables TenneT to test how the flexibility potential of battery storage systems can support congestion management. The pilot project will see an agent-based and a blockchain-based platform linked for the first time in order to give small-scale flexibility potentials efficient access to the system service markets.

    Background

    The expansion of renewable energies is increasingly leading to decentralised structures in the lower-level German energy distribution system. This will massively increase the number of small producers, storage facilities and consumers in the coming years. At the same time, the high feed-in of fluctuating renewable energies is leading to transport bottlenecks in the transmission network. In the future, there will be less and less conventional generation capacity from large power plants available to manage these network bottlenecks and to compensate for fluctuations in electricity generation and consumption. Once intelligently networked and integrated into the system service markets, the flexibility potential of millions of decentralised producers, storage facilities and consumers can make a major contribution to the control of power grids.

    Use of blockchain-based technologies

    The provision of system services for the control reserve market and congestion management from millions of individual systems requires a new approach to automated control and integration into the processes of TSOs, as well as technical solutions from device manufacturers and energy service providers. As such, TenneT has developed a cross-border blockchain-based data platform – the Equigy Crowd Balancing Platform – together with a number of European TSOs. This platform will make it easier for millions of households in Germany and Europe to actively offer the flexibility of their systems via electricity providers and manufacturers on the system service markets, and so help stabilise the electricity grid. Equigy enables the automated integration and control of these systems into the processes of network operators and market parties.

  • NordLink - the "green cable" - receives "PR Report Award 2021”
  • TenneT's digital-hybrid press event marks a milestone in Corona times in the "Technology and Innovation" category
  • Berlin/Bayreuth. NordLink has also won awards in the field of communication. In Berlin, the "green cable" for the exchange of German wind energy with Norwegian hydropower has now been honoured with the "PR Report Award" of the communications journal PR Report. The media staging of the opening ceremony of NordLink was honoured as outstanding communication in the category "Technology and Innovation". The press department of the transmission system operator TenneT had created a media event that set new standards for digital and hybrid events, the jury said in its laudation. 

    With a joint "digital push of a button", German Chancellor Dr Angela Merkel and Norway's Prime Minister Erna Solberg, together with TenneT CEO Manon van Beek, had officially commissioned NordLink in May 2021. The Chancellor emphasised: "NordLink is a milestone for sustainable energy supply and climate protection in Europe." 

    Simultaneously live-digital present and integrated into the push-button photo moment were also Federal Minister of Economics and Technology Peter Altmaier, the Minister President of Schleswig-Holstein, Daniel Günther, Markus Scheer, Member of the Management Board of KfW IPEX-Bank, Hilde Tonne, CEO of the Norwegian transmission system operator Statnett, Jon Fredrik Baksaas, Chairman of the Board of Statnett, as well as Norway's Minister of Energy Tina Bru. 

    Since the Corona pandemic made a joint analogue presence event impossible, TenneT's press department had completely redesigned the event schedule. The result was an impressive digital-hybrid live event that created a shared experience that went far beyond a mere push-button moment and dominated the international headlines. It was produced simultaneously in two studios in Berlin and Oslo and implemented with nine parallel live feeds from six different locations, including the Federal Chancellery, the Federal Ministry of Economics and the Kiel State Chancellery.

    TenneT's communication concept was developed in close cooperation with Public Dialogue Consultants from the Berlin agency navos and the Stuttgart event agency Tailormade. The opening ceremony, which was honoured in Berlin, exceeded all expectations internally among the NordLink project partners as well as among all external stakeholders and the media: NordLink's commissioning was not only on the front pages of all major newspapers and prime-time news in both Germany and Norway. Several TV and online stations in Germany and Norway had even broadcast the event live, and various international media also reported extensively.
    The awards for the communication industry PR Report Award 2021 were selected by an independent 37-member jury from 350 entries. The panel, chaired by PR Report Editor-in-Chief Daniel Neuen, had evaluated the submissions in a two-stage process and voted in secret at a joint meeting in Berlin.

    Background to NordLink

    NordLink serves the exchange of German wind energy with Norwegian hydropower and is the connection of two optimally complementary systems. The "green cable" has a capacity of 1,400 megawatts and can supply more than 3.6 million German households with renewable energy. This is comparable to the feed-in capacity of 466 wind turbines of three megawatts each. The capacity of this interconnector is equivalent to that of a very large conventional power plant.
    NordLink is a high voltage direct current motorway without an exit, i.e. a point-to-point connection, between the AC grids in Germany and Norway. Due to the length of the route and the large transmission power, direct current is used for low-loss transmission. The two cables (positive and negative pole) are connected to the converter stations at each end. The converter stations were built in Wilster (Schleswig-Holstein) and Tonstad (southern Norway). At these locations, the electricity is converted from DC to AC (or vice versa, depending on the direction of transmission) and fed into the German or Norwegian AC transmission grid to supply households and businesses with green electricity.
    NordLink was realised by a consortium in which the Norwegian transmission system operator Statnett and DC Nordseekabel GmbH & Co. KG each hold a 50% stake. TenneT and KfW each hold 50 percent of the shares in DC Nordseekabel.

  • The wind power booster realises acceleration potential of three years for Germany's ambitious climate targets
  • Energy Ministers Olaf Lies and Jan Philipp Albrecht and Economics Senator Kristina Vogt welcome TenneT's initiative for sustainable grid expansion in the North Sea and coastal regions
  • Industry and offshore sector support TenneT's proposal as an essential contribution to decarbonisation and smart coupling of wind energy with hydrogen  
  • The transmission system operator TenneT today presented a technological innovation that can significantly accelerate offshore grid expansion for wind power in the North Sea. With the wind power booster, six gigawatts of offshore capacity can be realised three years earlier. For comparison: six gigawatts of capacity correspond to six large power plants.
    The concept was presented in Germany together with the Energy Ministers of Lower Saxony, Olaf Lies, and Schleswig-Holstein, Jan Philipp Albrecht, as well as Bremen's State Councillor Kai Stührenberg - representing Bremen's Senator for Economic Affairs Kristina Vogt.

    The wind power booster is a first concrete step towards a long-term meshed high voltage direct current grid at sea and on land. A meshed direct current grid (HVDC overlay grid) on land and at sea ensures long-term security of supply and reduces the economic costs of integrating renewable energies to achieve the climate targets.
    Important companies, including e.g. ArcelorMittal, Entwicklungsagentur Region Heide, EWE, Holcim, Hynamics, Ørsted, Raffinerie Heide, Salzgitter AG, Uniper and the wind energy associations BWO and WAB support TenneT's initiative.

    TenneT COO Tim Meyerjürgens said: "Building on our extensive experience in the construction and operation of offshore grid connections, our conceptual and technological innovation for a six-gigawatt hub demonstrates a way to significantly accelerate the achievement of ambitious climate protection targets. We see this as an offer also for the German government coalition negotiations currently underway, which, as we know, are seeking a boost for the expansion of renewable energies in Germany. At the same time, we are laying the foundation for a sustainable interconnection of the direct current grid. In this way, we are sustainably increasing efficiency as well as security of supply and making an important contribution to the intelligent coupling of offshore wind with electrolysers to be built close to generation and the gas grid."

    Olaf Lies, Lower Saxony's Minister of Energy and the Environment, said: "The key role of offshore wind energy for the energy and climate goals becomes even clearer when we look at the cross-sectoral implementation of the energy transition - i.e. also the energy needs to be met by renewables outside the electricity sector. This will not be possible without green hydrogen and the green electricity it requires. In addition to the role in energy and climate policy, there is also the importance in terms of industrial and employment policy - for northern Germany, but also far beyond. Together with our neighbouring federal states, Lower Saxony has the chance to become the gateway for offshore energy for the whole of Germany. In order to be able to decisively use the opportunities of hydrogen technology in the sense of a sustainable energy supply for the local industry and business location, we must already create the technical prerequisites today and therefore also initiate a significant step in grid planning in the direction of a future-oriented, cost-efficient and internationally connected direct current grid. In view of the recent stagnation in the expansion of offshore wind energy, we also need approaches like this that allow us to pick up the pace again. Because time is otherwise running out. Preparing for the future multi-terminal deployment would also have direct benefits in Wilhelmshaven by requiring less space for the planned projects on site."

    "The concept presented to accelerate the expansion of offshore wind energy use while saving power lines is a building block in the right direction. We need to come up with a viable target concept as soon as possible on how we want to expand our infrastructure by 2045," said Schleswig-Holstein's Minister of Energy Jan Philipp Albrecht. "And we have to start planning for this today. We want a European energy transition and this includes a European system interconnection that includes not only electricity but also the production and transport of green hydrogen. We will take an integrative, interconnected approach and build strong future-proof energy infrastructures in the centre of Europe."

    Kristina Vogt, Bremen's Senator for Economic Affairs, Labour and Europe, said: "The commitment to renewable energies and in particular the increased expansion of offshore wind energy to achieve climate targets has long been one of my core concerns. The concept presented to accelerate the expansion of offshore wind energy is an excellent example of how this expansion can be achieved more quickly with creative ideas. As an industrial location with a significantly higher electricity demand in the future, the state of Bremen will benefit directly from this. Greenhouse gas emissions can be reduced and value creation and jobs secured at the same time."

    The concept at a glance

    With the wind power booster concept, TenneT is proposing very specific measures that will make it possible to integrate six gigawatts of offshore wind power into the power grid as early as 2032, instead of 2035, i.e. three years sooner than previously envisaged in the grid development plan, in a first step. The concept consists of the following building blocks:

    Advantage: Acceleration of offshore expansion

    TenneT is responsible for the construction of around 17 of the currently planned 20 gigawatts of offshore transmission capacity in the North Sea and Baltic Sea by 2030. With the proposed expansion path for a further six gigawatts by 2032, which was previously not planned until 2035, Germany's offshore expansion targets can be significantly increased in the short term and thus contribute to accelerated implementation on the path to climate neutrality.

    Advantage: International connections in the North Sea

    In order to achieve the European climate targets, the expansion of offshore wind energy in the North Sea must be planned across national borders in the long term. What is needed is a North Sea offshore grid that connects the riparian states. This is particularly important for Germany, as the German offshore wind potential will not be sufficient to achieve the German climate targets by 2045. The interconnection of several offshore connections from different states increases efficiency, security of supply and creates new European electricity trading capacities. The modular  concept of the LanWin hub enables, for example, interconnection with the Danish "energy island" and, in the future, with other North Sea countries. This distribution hub would be established in the LanWin area of the German Foreign Economic Zone in the North Sea, around 150 kilometres off the German coast.

    Advantage: Smart sector coupling at the coastal grid interconnection points

    Until now, offshore wind farms have always been connected to the onshore electricity grid by point-to-point connections. In order to achieve Germany's and Europe's ambitious climate targets, it is necessary to establish an internationally meshed direct current grid at sea and on land in order to transport more energy through the planned direct current lines on land. At the offshore grid interconnection points near the coast, in addition to decarbonising energy-intensive processes, intelligent sector coupling with planned electrolysis projects as well as with the gas infrastructure and the feed-in of onshore wind energy is planned.

    Advantage: Less land consumption on land

    In order to supply private consumers, industry and planned electrolysis projects with offshore wind energy, as well as to enable a direct connection with continuing direct current lines on land, the three offshore connections will land close to the coast in Heide (Schleswig-Holstein), Wilhelmshaven (Lower Saxony) and in the Bremen area. The wind power booster concept provides relief for the need for space and land in the coastal regions and at the same time offers new opportunities for the industrial clusters located there. Each of these three areas is to be integrated as a wind power booster with a two-gigawatt connection.

    Advantage: experience and innovation 

    TenneT has already realised 14 offshore grid connections in the Netherlands and Germany and thus operates more than half of the offshore grid connection capacity in the EU. TenneT uses the know-how it has developed in this way to the advantage of new projects. For the LanWin hub, TenneT is relying on its innovative two-gigawatt standard for direct current connections, supplemented by further technological developments for the wind power booster concept. The new standard aims to further reduce the costs of offshore grid expansion and minimise spatial and environmental impacts. 

    Supporters of the TenneT initiative

    Numerous companies from industry and the energy sector as well as industry associations support TenneT's initiative to accelerate the realisation of offshore expansion targets in the North Sea. TenneT is using the wind power booster concept: the construction of modular wind power hubs at sea and on land is combined with grid-serving locations that are suitable for industry. The aim is to link solutions for decarbonising energy-intensive processes in industry and for the smart coupling of wind energy with hydrogen with the creation of an international network of direct current lines. In addition, the direct interconnection of several offshore connections from different countries increases efficiency, security of supply and creates new European electricity trading capacities.

    • TenneT starts tender of 2GW stations (Platform & HVDC system) for Dutch IJmuiden Ver projects
    • First 2GW IJmuiden Ver project operational in 2028


    The European climate objectives are becoming more and more ambitious. If we want to meet the EU Fit for 55 targets, we need to speed up what we are doing three to four times. Offshore wind plays a crucial role in the energy transition: Europe wants to connect a total of 60 GW of offshore energy by 2030 and nothing less than 300 GW by 2050. Together with market parties, TenneT developed a new 2GW (Gigawatt) standard to be able to accelerate offshore wind deployment. The new standard aims to further reduce the costs of offshore wind and to minimise the spatial and environmental impact. The new 2GW standard will more than double the capacity in comparison to the previous 900 MW HVDC standard and almost triple the 700 MW AC standard. The new transmission standard supports the essential next step towards larger offshore wind farms and a North Sea wide European Hub-and-Spoke system – combining wind power connection, coupling of energy markets through interconnection and smart integration into the main onshore grids. As part of this development, the Dutch IJmuiden Ver projects will be hub ready to connect a future multi-purpose interconnector (WindConnector) to the UK.


    IJmuiden Ver projects

    TenneT will now start the tender of the stations (Platform & HVDC system) of the Dutch IJmuiden Ver projects. With this tender, TenneT enters the next phase for the innovative 2GW projects in the IJmuiden Ver wind area. It is expected that this contract will be awarded by the end of 2022. Recently the engineering for the land station was tendered and the cable contract will follow later this year. The first  2GW IJmuiden Ver connection is planned to be operational in 2028.


    Innovative cooperation TenneT and market parties

    Marco Kuijpers, director Large Projects Offshore at TenneT: "Wind energy from the North Sea plays the crucial role in realising the ambitious offshore wind goals for the Netherlands and Europe. Households and certainly heavy users such as the industry need to electrify. TenneT's experience in offshore grid development combined with the expertise and insight of market partners have resulted in the 2GW grid connection that will play a very important role in unlocking the North Sea Power House as the source of sustainable energy for not only the Netherlands and Germany, but in fact all of Northwest Europe."   


    About the 2GW Program

    To be able to accelerate we set up the 2GW Program. In this we combined our extensive know-how in offshore grid development with a unique transnational approach and developed a new offshore standard together with the market. With the 2GW Program we can really unlock the possibilities of the North Sea. So we can provide Europe and its inhabitants with even more green energy in a safe and cost-efficient way – all with the least environmental impact possible. With the 2GW Program, we increase the pace and tackle the future of the offshore grid expansion through harmonisation. At least six standardised offshore grid connections with a transmission capacity of 2 GW each will strengthen TenneT's role as driver of the European energy transition in the Dutch and German North Sea until 2030. The 2GW Program sets the new beat of the European energy transition.

    news-2468 Mon, 20 Sep 2021 15:04:35 +0200 TenneT, Örsted, Uniper: More offshore wind power for the decarbonization of Germany as an industrial location https://www.tennet.eu/tinyurl-storage/detail/tennet-oersted-uniper-more-offshore-wind-power-for-the-decarbonization-of-germany-as-an-industrial/ Both partners are receiving further support from the transmission system operator TenneT Both partners are receiving further support from the transmission system operator TenneT

    Uniper, one of Europe's largest power producers and a global gas trader, and Ørsted, the world market leader in the design, construction, and operation of offshore wind farms, are working together in the form of a strategic partnership.  Both companies each have ambitious visions in the area of decarbonizing the industry to achieve the German climate targets. The transmission system operator TenneT stands ready as a partner to support them and, among other things, to realize the transport of wind power from sea to land.

    In a Memorandum of Understanding (MoU), the companies Uniper and Ørsted have committed themselves to the goal of jointly developing offshore wind with hydrogen on a large scale. This is to be achieved in particular through a system-serving direct integration of hydrogen production from offshore wind power at the Wilhelmshaven site.

    Axel Wietfeld, CEO of Uniper Hydrogen: "Germany and Europe must remain strong industrial locations – and at the same time achieve the ambitious climate protection targets. For this, we need "green electrons" and "green molecules". Through the strategic partnership with Ørsted, we have exactly the right setup to combine economic and ecological goals directly on site in Wilhelmshaven. By integrating offshore wind and hydrogen, we can significantly support industries such as  the chemical, steel or transport sectors in their decarbonization. “

    Jörg Kubitza, Germany Managing Director of Ørsted: "Green hydrogen from offshore wind power is the driver of German decarbonization, as it plays a key role for future climate neutrality. Therefore, Germany as an industrial location needs much more green electricity than previously planned. I am very pleased that in Uniper we have a partner at our side who will continue to push and promote the generation of renewable offshore wind power with us in order to be able to achieve Germany's climate targets.“

    Tim Meyerjürgens, COO of TenneT: "Integrated planning of electricity and hydrogen will become the key factor in a successful energy transition. Electrolysis must take place where renewables are generated and available in sufficient quantities, namely primarily on the coasts. As a reliable partner in shaping the energy transition, TenneT stands ready to support Ørsted and Uniper in their ambitious goals."

    Uniper began developing the "Wilhelmshaven Green Hydrogen" project in 2020. It is expected that an electrolysis plant with a capacity of 70 megawatts (MW) will be installed from 2025, to be expanded to 410MW by 2030. The renewable electricity required for the electrolysis will prospectively come from Ørsted offshore wind turbines. Thanks to the existing substations and its proximity to the coast, the Uniper site in Wilhelmshaven has all the necessary prerequisites to play a key role in the local energy transition. In addition, the direct conversion of renewable electricity into green hydrogen means that any power grid bottlenecks can be avoided.

    Wilhelmshaven could develop into a hydrogen center for Lower Saxony and serve as an example for similar projects.

    In addition, Uniper and Orsted are investigating CO2-free alternatives for stabilizing power grids, as well as green solutions for industrial customers with a high level of supply security – even in the event of possible dark periods.

    EIB signs a EUR 250 million loan agreement with TenneT to fina nce the 40km high voltage electricity transmission corridor in the North of the Netherlands between Eemshaven and Vierverlaten, as well as the new high voltage substation in Vierverlaten.

    The upgraded energy infrastructure will, amongst others, support the connection of North Sea wind farms to the electricity grid and ensure a high security of supply

    This financing increases the aggregate total EIB commitment to TenneT projects to EUR 1.8 billion.

    The European Investment Bank (EIB) has signed a EUR 250 million loan agreement with TenneT Holding B.V. The financing will be used to build a 40-km long electricity transmission corridor from Eemshaven to Vierverlaten in the province of Groningen, in the north of Netherlands, enabling the transmission of rapidly growing amounts of offshore wind energy to users in the Netherlands and beyond. The new electricity transmission corridor will double the capacity of the existing 220kV circuit. The corridor financed by the EIB includes a new 380kV line from Eemshaven to Vierverlaten, combined with a 110kV line for part of the route, and a new 380/220kV substation in Vierverlaten.

    Once the new transmission lines are operational in 2024, the existing smaller capacity lines along the same route will be decommissioned and the project will result in an overall doubling of the capacity of the existing 220kV circuit. The new grid connection will allow for the avoidance of congestion on the Netherlands’ high voltage grid, especially once nearby wind farms under development are brought into operation and the project will further facilitate transfer of green electricity to demand centres. Eemshaven is already an important power generation hub in the Netherlands and this position will only be strengthened as, for example, it recently was designated also as the landing point for the planned offshore wind farm "Ten noorden van de Waddeneilanden" (700MW), by the Dutch Ministry of Economic Affairs.

    “Supporting clean energy transmission is one of the key goals for the EIB, as the EU Climate Bank.” stated EIB Vice-President, Kris Peeters. “The Netherlands’ ambitious targets for renewable energy generation would require more investment in the transmission network and I am pleased that the EIB can help provide financing to contribute to achieving these goals. This project will help to bring secure, sustainable electricity to users across the Netherlands and beyond.”

    Otto Jager, TenneT’s Chief Financial Officer, added: "TenneT is one of the largest investors in the European energy transition and long term partners as the EIB are needed to help finance this. Today’s transaction underlines our strong relationship with the EIB and we are proud that the EIB is financing this corridor which qualifies as a project of Common Interest of the European Union."

    The EIB has increased its total lending commitment to TenneT. With EUR 1.8 billion, the EIB is TenneT's largest lender. The EIB commitments are provided for the upgrading and expansion of TenneT’s electricity transmission networks in the Netherlands and Germany as well as (cross country) interconnectors.

    news-2453 Thu, 02 Sep 2021 07:30:00 +0200 TenneT expects structural congestion, as referred to in Article 9.5 of the Electricity Grid Code, in the 150kV grid in Flevoland and Gelderland during the period 2021-2029 https://www.tennet.eu/tinyurl-storage/detail/tennet-expects-structural-congestion-as-referred-to-in-article-95-of-the-electricity-grid-code-in/ The expected congestion is caused by the rapid growth of solar and wind production in the grid of the regional grid operator (Liander) and in TenneT's grid. The resulting higher transport demand cannot be fully facilitated due to the limited available transport capacity in the high-voltage grid.  The expected congestion is caused by the rapid growth of solar and wind production in the grid of the regional grid operator (Liander) and in TenneT's grid. The resulting higher transport demand cannot be fully facilitated due to the limited available transport capacity in the high-voltage grid. 

    What is the contracted and available transmission capacity?

    The congestion area covers all 150kV-stations in the province of Flevoland (Flevopolder) and all 150kV-stations in Gelderland. In this congestion area, the total contracted transmission capacity is approximately 5,600 MW. The total available transmission capacity (stations Lelystad, Dodewaard, Doetinchem) amounts to approximately 3350 MW. This capacity is fully allocated in signed tenders for contracted transmission capacity. There are no restrictions with regard to consumption; only with regard to feed-in.

    Planning the grid reinforcement

    The structural solution consists of splitting the meshed 150kV Flevoland-Gelderland-Utrecht grid into at least four grid sections, each with its own connection to the 380kV grid, increasing the 150/380kV transformation capacity and possibly upgrading 150kV connections. The increase in transformation capacity will be completed in phases during the period 2026-2029.

    Research

    TenneT is to start a study into the possibilities for applying congestion management in the area mentioned in Article 9.5(5) of the Electricity Grid Code. After its completion, the study will be published on TenneT's website.

    news-2455 Thu, 02 Sep 2021 07:30:00 +0200 High-voltage grid in Gelderland and Flevopolder reaches limit for electricity feed-in https://www.tennet.eu/tinyurl-storage/detail/high-voltage-grid-in-gelderland-and-flevopolder-reaches-limit-for-electricity-feed-in/ The high-voltage grid in the provinces of Gelderland and Flevopolder is reaching the limit of what can be returned to the grid. The high-voltage substations and connections in this area are reaching the maximum limit of what can be transported. Over the next few years TenneT will make various investments to increase the capacity of the grid. At the same time, the transmission system operator will investigate the possibilities of using other solutions to create more space on the grid in an accelerated manner. This is evident from the formal notification that was made today to the ACM, the regulator of the energy market.

At the same time, the transmission system operator will investigate the possibilities of using other solutions to create more space on the grid in an accelerated manner. This is evident from the formal notification that was made today to the ACM, the regulator of the energy market.

    The rapid growth of wind and solar farms in Gelderland and the Flevopolder together generate a large amount of sustainable energy, which demands increasing capacity from the high-voltage grid. Throughout the region, 4800 megawatts of sustainable generation have now been developed or are under preparation. This is comparable to the capacity of six large power plants. This development will lead to bottlenecks in the grid, especially at times when there is a lot of wind and sun and little consumption of electricity in the regions concerned. TenneT will structurally resolve these bottlenecks by means of reinforcements, including the installation of additional transformers and adjustments to the regional high-voltage grid. The expected expansion will take place in phases and is expected to last between three and seven years.

    Long-term planning and cooperation are crucial to achieving climate targets

    Robert Kuik, TenneT Manager of Grid Planning: "The development of sustainable energy production continues at an unabated pace. All these developments require adjustments to the high-voltage grid and creative solutions to create extra space on the grid. Long-term planning and cooperation between all parties are crucial in order to meet the climate targets, also because expansion and modification of the high-voltage infrastructure takes a long time and the available technical capacity is scarce.

    €450 million grid investments

    Over the next few years TenneT will continue to invest in the Flevopolder and Gelderland regions in order to increase the capacity of the grid. The grid manager will install additional transformers in Dodewaard, Doetinchem and Lelystad, among other places, in order to better distribute electricity across the grids. In the Flevoland Polder, work is in progress to connect three large new wind farms to the national grid. TenneT is expected to invest 450 million euros in the regions on the way to 2030.

    Research into congestion management

    When structural bottlenecks occur on the electricity grid, the grid manager also initiates a formal investigation into the possibilities of applying congestion management, based on laws and regulations. This is a method based on the electricity market to create more space on the grid and at the same time prevent overloading of the electricity network.

    news-2436 Mon, 02 Aug 2021 08:00:00 +0200 Underwater robot laying cables successfully crossed the Rotterdam Maasmond to connect Hollandse Kust (zuid) https://www.tennet.eu/tinyurl-storage/detail/underwater-robot-laying-cables-successfully-crossed-the-rotterdam-maasmond-to-connect-hollandse-kust/ North of the Maasvlakte, TenneT is developing the Hollandse Kust (zuid) offshore grid for the connection of new wind farms. Four offshore cables will be buried in the North Sea bed. For the first ten kilometres of the offshore cable route, these cables will be sunk 5.5 metres into the seabed to cross the busy Rotterdam "Maasmond". The first two cables were installed in September 2020 and now the remaining cables will follow. Tuesday the underwater robot 'Deep Dig-It' has successfully crossed the Rotterdam Maasmond with the third cable and is now on its way to the recently installed Beta jacket in the Hollandse Kust (zuid) wind area. North of the Maasvlakte, TenneT is developing the Hollandse Kust (zuid) offshore grid for the connection of new wind farms. Four offshore cables will be buried in the North Sea bed. For the first ten kilometres of the offshore cable route, these cables will be sunk 5.5 metres into the seabed to cross the busy Rotterdam "Maasmond". The first two cables were installed in September 2020 and now the remaining cables will follow. Tuesday the underwater robot 'Deep Dig-It' has successfully crossed the Rotterdam Maasmond with the third cable and is now on its way to the recently installed Beta jacket in the Hollandse Kust (zuid) wind area.

    Preparations completed

    The Van Oord - Hellenic Cables consortium is installing the two cables to the Beta platform. The interlinking cable, which connects the two offshore platforms, was already successfully installed at the Alpha and Beta jackets. The preparatory work was completed during the past few days. The cable that will be installed to the Beta jacket has been pulled ashore through the jackets to the newly built onshore transformer station on the Maasvlakte. Now, the consortium combination will lay the cable with a total length of 34 kilometres to the wind area Hollandse Kust (zuid). Van Oord developed the Deep Dig-It, a gigantic, remote-controlled underwater trencher, especially for this project.

    Cable installation

    Van Oord's Deep Dig-It is a Tracked Remotely Operated Vehicle (TROV) that travels on the seabed unmanned, making a deep trench for the cables by liquefying the seabed. At the same time, this underwater trencher lays the cables in the trench and closes it. The Beta cables weigh approximately 100 kilograms per metre and consist of three cores. These three cores are made of aluminium and the cable has a diameter of 30 centimetres. Both cables were loaded onto spools on the cable vessel "Living Stone". This cable vessel runs on liquid gas (LNG), which reduces emissions. The installation of the 34 kilometres of cable route will take about four weeks and is expected to be completed by mid-September.  
    At the end of this year, the topside, the transformer station itself, will be lifted onto the Alpha jacket. The topside of the Beta jacket is expected to follow early next year. Once the platforms have been lifted onto the jacket, the last systems will be connected, tested and put into operation. The cables of the wind turbines will then be connected to the high voltage substation on land  and the wind farm is expected to be fully operational in 2023.

    Hollandse Kust (zuid)

    The grid connection for Hollandse Kust (zuid) is located 22 kilometres off the coast of the Dutch province of South Holland. It consists of two transformer platforms at sea, each with two 220 kV alternating current cables. The sustainably generated electricity is transported to land via these cables. TenneT has built a new high voltage substation and is expanding the high-voltage 'Maasvlakte 380 kV' substation. From this high-voltage substation, offshore wind energy will be fed into TenneT's Randstad 380 kV South ring. The wind energy goes to the electricity consumers in the country via the national high-voltage grid.

    Connecting offshore wind energy up to 2030

    In the period up to and including 2023, TenneT will install 3.5 GW of offshore grid connections for wind farms at sea. For these wind farms, TenneT will use the same type of 700 MW transformer platform five times, located close to a wind farm, and the same type of 220kV cable connection to the coast five times. This standardisation will enable TenneT to build these projects more efficiently, faster and cheaper. According to the follow-up Wind at Sea Roadmap, a further 6.1 GW of offshore wind farms will be developed between 2024 and 2030. This concerns the wind farms in the wind energy areas Hollandse Kust (west), TenneT is again using three standardised 700 MW platforms (2.1 GW) for the first two areas. For the efficient connection of the wind energy areas further out in the North Sea, such as IJmuiden Ver (4 GW), other techniques are needed based on direct current instead of alternating current. At least two offshore connections of 2 GW each will be developed for IJmuiden Ver. In addition, a third 2 GW connection is being studied for IJmuiden Ver, in parallel with the other IJmuiden Ver projects.

    Offshore grid connections Germany

    In the German part of the North Sea, TenneT alone exceeded the German government's 2020 target already a year in advance and operates today 7.1 GW. Until 2030 TenneT's offshore grid connection capacity in Germany will be increased to approximately 17 GW.

  • In the first half year of 2021 TenneT, as a major enabler of the energy transition, was once again able to maintain a high security of supply of 99.99 percent for its 42 million Dutch and German end users. At the same time, higher European and national political targets to reduce CO2 emissions, a need for consensus among European countries on a clear, legal and regulatory European roadmap and the often complex integration of renewable energy solutions and corresponding new infrastructure into our living environment increase TenneT's efforts.  

    Manon van Beek, CEO: "As Europe's first cross-border TSO with expected annual investments to grow to EUR 5-6 billion, TenneT aims to achieve a timely delivery of onshore and offshore extensions and investments. Our energy system is undergoing a revolutionary development in which the high voltage electricity grids - the backbone of the energy system - are being used in a completely different way. Once built to meet the demand for energy, now it is changing into a multifunctional connector of electricity supply, demand and storage."

    Financial results

    TenneT’s financial performance in the first half year of 2021 remained solid. Underlying revenue of EUR 2,568 million increased by 10.7% compared to 2020 (EUR 2,319 million), mainly driven by a growing asset base and additional compensation for grid-related expenses.

    Key Results First Half Year of 2021

    High capacity connections to transport green electricity

    TenneT is showing very good progress on a large number of projects. Several thousand kilometers of new connections came and will come into operation in 2021, are under construction or are in the planning phase. Flagship project NordLink, the 1,400 MW subsea DC cable between Germany and Norway, is now fully in operation. For the first time, the electricity markets of both countries are directly connected,  ensuring the exchange of large amounts of sustainable power and additional security of electricity supply.

    TenneT's two largest onshore DC corridor projects SuedLink and SuedOstLink will be built completely underground and are crucial to transport northern wind production to meet demand for electricity in southern Germany. For SuedOstLink the orders for the converters were placed. For SuedLink partnering transmission system operators TenneT and TransnetBW welcomed the completion of the federal spacial planning. With this procedure, the Federal Network Agency ('Bundesnetzagentur') has made the almost 700-kilometer corridor of SuedLink binding.

    In the Netherlands TenneT connected wind farm Fryslân, which is the largest wind farm on an inland waterway in the world. A 55 kilometer long underground cable was used to connect the wind farm to the electricity grid. This is the longest underground high-voltage (110 kV) cable connection in the Netherlands.

    In April, crucial parts of the new high-voltage (380 kV) connection between Borssele and Rilland were installed. This power highway is essential for transporting the electricity of the existing and future wind farms in the North Sea in the southwest of the Netherlands. In addition, the new connection is important for the exchange of electricity with Belgium. The connection will be commissioned in 2023.

    According to planning the second jacket of TenneT's offshore transformer platform for the wind farm Hollandse Kust (zuid) has been installed. TenneT is realizing 3.5 GW of offshore grid connections for wind farms at the Dutch North Sea until 2023 using the same type of 700 MW transformer platform five times. This enables TenneT to build these projects more efficiently, faster and more affordable. Until 2030, TenneT is building 11.6 GW of offshore connection capacity for large offshore wind farms in the Netherlands.

    In Germany, that will be 16.7 GW, according to plan. In both countries use will be made of innovative 2 GW direct current connection systems, developed by TenneT together with suppliers and offshore wind farm developers.

    Paving the path for necessary system integration

    Integrated system planning, cooperation across borders, offshore and onshore, electrons and molecules. All are needed to meet the requirements of a new, smart and affordable energy system to be built between 2030 and 2050. That is why TenneT, Gasunie and the Dutch DSOs published the so-called II3050 (Infrastructure Outlook 30-50) in April. Some of the important conclusions: the infrastructure for electricity must be expanded on a large scale, a nationwide hydrogen transport pipeline network is needed, infrastructure for heat and CO2 must be constructed and more speed is needed since the current lead times for adjustments in the grid lead to bottlenecks. The fact that the Dutch government announced to come up with a plan to adapt existing natural gas transmission pipelines for the transport of hydrogen ('hydrogen backbone') is a direct and gratifying result of the insights presented in the II3050.

    Looking Ahead

    Elections and energy policy

    The formation of a new Dutch government and the German Bundestag elections later this year provide an excellent opportunity to make political choices based on social considerations. This concerns pressing matters such as costs, space requirements and feasibility. Clear roadmaps are needed for increased climate ambitions. Cooperation between governments, infrastructure companies and industry is of utmost importance.

    news-2431 Mon, 26 Jul 2021 10:00:00 +0200 Offshore share of total wind energy yield increases despite low wind in first half of 2021 https://www.tennet.eu/tinyurl-storage/detail/offshore-share-of-total-wind-energy-yield-increases-despite-low-wind-in-first-half-of-2021/ North Sea wind is becoming increasingly important for the success of the energy transitionTenneT is building 16 more offshore grid connections by 2030, increasing transmission capacity to around 29 gigawatts in the German and Dutch North Seas
  • North Sea wind is becoming increasingly important for the success of the energy transition
  • TenneT is building 16 more offshore grid connections by 2030, increasing transmission capacity to around 29 gigawatts in the German and Dutch North Seas
  • In the first half of 2021, the wind energy transmitted from the German North Sea to shore by the transmission system operator TenneT amounted to 9.673 terawatt hours (TWh)*. Although this is around 16 percent less than in the first half of 2020 (11.51 TWh), the share of North Sea electricity in total wind power generation in Germany rose to 16.63 percent. This is 6.6 per cent more than in the first half of 2020, when the North Sea share was 15.6 per cent of total wind power generation. 

    In the Netherlands, the TenneT offshore grid connections transmitted 2.38 TWh in the first half of the year, which was a good 30 percent more than in the whole of 2020 (1.82 TWh).  This is due to further expansion and the commissioning of the Borssele Beta offshore grid connection system in the second half of 2020. A further 1.5 TWh was fed directly into the Dutch TenneT grid onshore from Dutch offshore wind farms in the first half of 2021. 

    "The decline in offshore wind energy fed into the German grid is purely weather-related," said TenneT COO Tim Meyerjürgens, "there was simply less wind on the German North Sea in the first half of 2021 than in the first half of 2020," he said, adding that this was even more true for German onshore wind output, which fell by almost 22 per cent in the same comparison period - from around 60 TWh to around 47 TWh.

    Tim Meyerjürgens continues: "Especially in years with less wind, the ratio of wind energy generated shifts towards offshore. There we generate on average about twice as many full-load hours as onshore and can thus partially compensate for lulls onshore. This shows the importance of the further expansion of offshore wind energy for security of supply and for a successful energy transition."

    At the same time, politicians are increasing climate targets and electricity demand expectations, which is leading to ever greater technical challenges for TenneT as a transmission system operator. TenneT is facing up to this and is working successfully and at full speed on further grid expansion on land and at sea. TenneT already operates more than half of all offshore grid connections capacity in the EU. By 2030, TenneT will realise 16 more and then provide almost 29 gigawatts of wind power transmission capacity in the North Sea. In the same period, TenneT will invest around 20 billion euros in the Netherlands and Germany for this purpose.      

    An important focus at TenneT is on increasing the efficiency of the offshore connections and their future interconnection. To this end, solutions like the North Sea Wind Power hub programme with integrated interconnection solutions will be a major, important step forward. TenneT is part of a consortium working on this with the aim of having a first project ready for operation in the early 2030s.

    Tim Meyerjürgens: "In order to achieve the increasingly ambitious climate and expansion targets in Europe, our constant technical innovations are leading the way. The expansion steps in the offshore grid from 700-megawatt AC and 900-megawatt DC connections to future DC connections with two gigawatt capacity give our projects the necessary thrust for a successful energy transition. And we need more bold ideas to consistently develop and improve the offshore grid."

    At TenneT, this also includes measures that reduce CO2 emissions. For example, an LNG-powered laying vessel has now been used for the first time in the laying of offshore power cables during the construction of the DolWin6 grid connection project. The next deployment of this vessel is already in preparation at TenneT.

     

    Further offshore balance data

    In the German North Sea, the maximum value of the feed-in capacity of offshore wind farms in the first half of 2021 was measured on 29 January at 6,357 megawatts (MW). In the Netherlands, the maximum value was 2,252 MW on 19 January 2021. The capacity of Dutch offshore wind farms was 2,440 MW on the cut-off date of 30 June 2021.

    In the German North Sea, the capacity expansion of offshore wind farms is stagnating. Capacity has remained unchanged at 6,679 MW since 2020.

    Wind turbines in the Baltic Sea (50Hertz grid area) generated 1.819 TWh in the first half of 2021, 17.5 per cent less than in the first half of 2020 (2.205 TWh). Germany's total offshore wind output in the North Sea and Baltic Sea was therefore 11.492 TWh in the first half of 2021.  Adding 46.657 TWh*) of onshore wind energy generated, the total wind yield in Germany comes to 58.15 TWh*).

  • TenneT continues successful pilot projects on the use of electromobility for the security of electricity supply as a partner in the joint research project "Bidirectional charging management - BDL"
  • Intelligent charging control of electric cars can help stabilise the power grid and thus limit grid expansion
  • BDL project: First test vehicles delivered - testing in everyday life begins
  • In a broad-based pilot project "Bidirectional charging management - BDL", the transmission system operator TenneT is investigating technological solutions to use the intelligent bidirectional charging control of electric cars for grid stability. TenneT is working together with partners from the automotive industry, charging infrastructure, energy industry and science. The project, which was launched in 2019, has now entered the important test phase with the handover of 20 test electric vehicles - BMW i3s - to customers. A further 30 vehicles will be handed over to commercial users over the next few weeks. This will link electric vehicles, charging infrastructure and electricity grids with a holistic approach in such a way that regeneratively generated energy is promoted in an increasingly complex energy system while maintaining security of supply at the highest level.

    TenneT has already been driving various initiatives in the field of electric mobility for years with partners such as BMW and Nissan, which are investigating how the charging strategy of electric vehicles can be intelligently coordinated with the utilisation of the electricity grid and the availability of renewable energy. "We are interested in finding new ways to flexibly control renewable electricity production, which is highly dependent on the weather, and thus relieve the burden on the electricity grid. Intelligent charging control of electric vehicles can complement grid expansion and become one of the building blocks of the energy transition," said TenneT COO Tim Meyerjürgens. "And at the same time, of course, we also want to give the owners of electric vehicles the opportunity to contribute to the successful implementation of the energy transition as active customers."

    In the future, electric vehicles with their battery storage systems could be used for so-called system services, which today are mainly provided by conventional large-scale power plants. These include the balancing of transport bottlenecks in the electricity grid and frequency deviations. Because more and more conventional power plants are being switched off as the energy transition progresses, TenneT is also investigating in the BDL pilot project how new flexibility options below 100 kilowatts - including electric vehicles - can be integrated into the system service processes and markets in the future.

    An important development here is the Equigy Crowd Balancing Platform. With it, TenneT, in cooperation with a number of other European transmission system operators, has created the prerequisite for electric vehicles to be easily and cost-effectively integrated into the system service markets.

    About the BDL Research project

    The ability to charge bidirectionally enables electric vehicles, when connected to a charging station or wallbox designed for this purpose, not only to absorb electrical energy, but also to feed it back into the power grid in the opposite direction. The batteries of the electric vehicles thus become mobile energy storage units that can also deliver electricity when needed. Such an integration of as many electric vehicles as possible into the power grid requires a variety of innovations in the areas of vehicle technology, charging hardware, charging management and communication interfaces to the energy industry stakeholders as well as with regard to legal framework conditions.

    These were developed by the participating partners in the first phase of the BDL project. In addition to the consortium leader BMW Group and the transmission grid operator TenneT, the distribution grid operator Bayernwerk Netz GmbH (both grid operators: energy system services), KOSTAL Industrie Elektrik GmbH (development charging hardware), KEO GmbH (software supplier for connecting customers to the energy providers), Forschungsstelle für Energiewirtschaft e.V. and Forschungsgesellschaft für Energiewirtschaft mbH (both: FfE, research on power system and grid feedback & measurement data evaluation), Karlsruher Institut für Technologie (KIT; research on electricity market and grid repercussions) and the university of Passau (user research) are involved. The research project under the auspices of the German Aerospace Center (DLR) is funded by the Federal Ministry for Economic Affairs and Energy and is scheduled to run for three years.

    With the delivery of the test vehicles to private and commercial users, the testing of the technology package previously developed by the participants now begins in everyday life. This essentially consists of the technology in the vehicle and backend (BMW), the intelligent wallbox (KOSTAL) and the networking of the electric vehicle, wallbox and electrical installation of the customer building with the electricity grid (Bayernwerk, KEO and TenneT). In the first phase, self-consumption from the power generated by the users' own photovoltaic system will be optimised. In the second phase, "vehicle to grid" functions are added, with which users can participate in new business models for energy trading and electricity grid stabilisation. In a third phase, users with electric vehicle fleets will be added. These will use the vehicles as short-term storage to avoid power demand peaks in the daily load profile.

  • Reducing their carbon footprint and developing their transmission infrastructure to integrate renewables into the system and support electrification are the main ways they are helping to achieve this goal
  • Reducing and limiting the carbon footprint of their own activities and value chains; expanding and developing their electricity grids to facilitate the integration of renewables and flexibility resources into the system; and supporting the direct and indirect electrification of different sectors of the economy: these are key ways 8 leading transmission system operators (TSOs) are helping to establish a climate-neutral society by 2050. In a paper published today, TSOs from Austria, Belgium, France, Germany, Italy, the Netherlands, Spain and Switzerland have launched a joint initiative which highlights the enabling role they are playing in the energy transition and provides concrete examples of their enabling activities. The group of TSOs teamed up to further analyse how their activities contribute to decarbonisation and develop ways to support the energy system to become carbon-neutral. They are strongly committed to reducing global greenhouse gas (GHG) emissions, supporting sustainable development and helping to transform the electricity sector as it moves from being fossil-based to being decarbonised.

     

    In line with the aims of the 2015 Paris Agreement, the European Green Deal and related “Fit for 55” legislative package, the EU and Switzerland have committed to achieving carbon neutrality. In line with this, TSOs can contribute to decarbonisation and the mitigation of global warming. The core of their activities and responsibilities is to ensure the secure and high-quality delivery of electricity across national and interconnected transmission grids, which are the backbone of European society. However, the role TSOs play has been widening. They are having to manage an increasingly complex and digitalised energy system as Europe prepares itself for carbon neutrality; this energy system is one in which the share of fluctuating renewable energy sources and electricity uses are growing and in which consumers are gradually being empowered to take on active roles.

     

     

    The electricity network will become the backbone of a greener energy system

    As outlined in long-term energy scenarios, which predict the widespread adoption of electrical assets such as electric vehicles and heat pumps, electricity will play a key role in the decarbonisation of the economy due to the higher efficiency of electrical end uses and the integration of renewables into the energy system. The electricity grid will become the backbone of a greener energy system and the work of TSOs will be crucial for achieving Europe’s climate goals. TSOs are, therefore, currently playing the role of energy transition enablers: they are facilitating the decarbonisation of the European electricity system and, consequently, the decarbonisation of society as a whole, and are using complex and innovative tools to do so.   

    TSOs limit both their own carbon footprint (known as ‘direct emissions’) and the carbon footprint of their value chains (‘indirect emissions’)

    TSOs monitor their direct and indirect GHG emissions in line with international GHG emission standards and implement measures to reduce them. Measures taken in this respect include reducing SF6 leaks and replacing SF6 gas with more favourable alternatives; efficiently developing their infrastructure to limit grid losses; employing energy efficiency measures; implementing green procurement procedures; and adopting circular economy approaches.

    TSOs integrate renewables and flexibility into the energy system and support electrification
    The share occupied by renewable energy sources is growing and consumers are being empowered to take on active roles in the system. By occupying a unique role in the energy value chain, TSOs are enabling the energy transition through a wide range of activities, from expanding their grids to facilitating the integration of renewable energy, new electrical uses and flexible assets into the system. Alongside these activities, TSOs are also facilitating developments in market design and regulatory frameworks, embedding digitalisation across their networks and investing in research and development.

    TSO activities impact the decarbonisation of the system as a whole

    Given the crucial nature of their activities, an assessment of the performance of TSOs with regard to sustainability and decarbonisation should not stop at evaluations of their carbon footprint. Moreover, in order to strengthen their work, TSOs should be explicitly recognised at European level as enablers of the energy transition and their activities should be clearly mentioned in GHG emission inventories under common assessment and monitoring frameworks, alongside GHG emission sources already associated with their carbon footprint.

    The paper comprises a detailed overview of TSO activities and their contribution to the decarbonisation of European society. It includes a number of flagship grid maintenance and development projects undertaken by the paper’s authors, which illustrate their activities and contribution to decarbonisation in a tangible way.

The 2,852-tonne heavyweight was placed on the bottom of the North Sea by a special lifting vessel (the Sleipnir) of the Dutch company Heerema, on behalf of main contractor Petrofac. The jacket left the  fabrication yard end of May in the United Arab Emirates, where it was built. The jacket is the foundation on which the transformer platform will be placed. The connection for the wind farms will be ready for use in 2022. The second jacket of TenneT's offshore transformer platform for the wind farm Hollandse Kust (zuid) has arrived at its final destination and has been installed, some 22 kilometres off the coast of The Hague. The 2,852-tonne heavyweight was placed on the bottom of the North Sea by a special lifting vessel (the Sleipnir) of the Dutch company Heerema, on behalf of main contractor Petrofac. The jacket left the  fabrication yard end of May in the United Arab Emirates, where it was built. The jacket is the foundation on which the transformer platform will be placed. The connection for the wind farms will be ready for use in 2022.

    Foundation

    The jacket is 50 metres long, 34 metres wide and 44 metres high and is anchored to the seabed by six piles, each weighing 162.5 tonnes. The 57.7 metre long piles were drilled 46.5 metres into the seabed. The jacket was then attached to the piles. Together, this forms the foundation for one of the two  transformer stations for the wind farm Hollandse Kust (zuid). The transformer platforms will have a capacity of 700MW each. The first jacket for the Hollande Kust (zuid) wind farm has been installed in the North Sea in September last year. The wind farm is developed by Vattenfall, in co-ownership with BASF.

    The superstructure (or topside), the transformer station itself, will be lifted onto the first jacket at the end of this year. The topside of the second jacket is expected to follow early next year. Once the topsides have been lifted onto the jacket, the last systems will be connected, tested and put into operation. The cables of the wind turbines will then be connected and the wind farm is expected to be fully operational in 2023.

    Milestone

    The installation of the second jacket is an important milestone for TenneT. "The past year has been characterised by uncertainty and challenges due to the COVID pandemic. Not only for TenneT, but also for our contractors and suppliers. Nevertheless, together we succeeded in achieving this performance. We can be proud of that," said Marco Kuijpers, TenneT's Director Offshore Projects.

    Hollandse Kust (zuid)

    The grid connection for Hollandse Kust (zuid) is located 22 kilometres off the coast of the Dutch province of South Holland. It consists of two transformer platforms at sea, each with two 220kV alternating current cables. The sustainably generated electricity is transported to land via these cables. TenneT has built a new onshore transformer station there and is expanding the high-voltage 'Maasvlakte 380kV' substation. From this high-voltage substation, offshore wind energy will be fed into TenneT's Randstad 380kV South ring. The wind energy goes to the electricity consumers in the country via the national high-voltage grid.

    Connecting offshore wind energy up to 2023

    TenneT is realising 3.5GW of offshore grid connections for wind farms at sea until 2023. With the completion of Borssele Alpha and Beta, the first 1,4GW has been realised  in 2020. This will be followed by Hollandse Kust (zuid) Alpha and Beta and Hollandse Kust (Noord). For these wind farms, TenneT uses the same type of 700MW transformer platform five times, located close to a wind farm, and the same type of 220kV cable connection to the coast. This standardisation enables TenneT to build these projects more efficiently, faster and more affordable.

    Programme Net at Sea 2024-2030

    According to the follow-up "Wind at Sea Roadmap", a further 6.1GW of offshore wind farms will be developed between 2024 and 2030. This concerns the wind farms in the wind energy areas Hollandse Kust (west) and Ten Noorden van de Waddeneilanden, TenneT is again using three standardised 700MW platforms (2.1GW) for the first two areas. For the efficient connection of the wind energy areas further out in the North Sea, such as IJmuiden Ver (4GW), other techniques are needed based on direct current instead of alternating current. At least two offshore connections of 2GW each will be developed for IJmuiden Ver. In addition, a third 2GW connection is being studied for IJmuiden Ver, in parallel with the other IJmuiden Ver projects.

    Offshore grid connections Germany

    In the German part of the North Sea, TenneT alone exceeded the German government's 2020 target already a year in advance and operates today 7.1GW. Until 2030 TenneT's offshore grid connection capacity in Germany will be increased to approximately 17GW.

    Amsterdam, June 16 2021NewMotion, a leader in smart EV charging solutions and a Shell group company, announces today that it’s the first charge point operator to receive a licence to deliver grid balancing services. NewMotion will enable this functionality on its existing install base of smart chargers, making it instantly available to thousands of customers. By simultaneously managing the charging speeds of its connected chargers, NewMotion is the first EV charging company to deliver grid balancing services at a megawatt scale which is equal to the energy consumption of a 1,000 households, aggregating individual electric vehicles into a virtual battery.

    A more sustainable alternative for grid balancing

    With the increasing amount of renewable energy on the grid, causing a higher intermittency and more grid deviations, there is more need for grid balancing. Grid balancing using electric vehicles is a sustainable alternative to the existing solutions. On a larger scale, EVs can help reducing the need for industrial coal and gas turbines that need to be fired up.

    NewMotion will deliver grid balancing services to TenneT for frequency containment reserve (FCR). FCR is the most important means to mitigate large power generation outages. With their reserves, parties can help Transmission System Operators like TenneT keep the European grid balanced at 50Hz frequency and prevent blackouts. NewMotion’s network of smart chargers can respond to deviations in the grid frequency within seconds. This is up to 600% faster than fossil fuel based alternatives, while not having a significant impact on the charging experience.

    As the first EV charging solutions provider in Europe licenced for FCR, we’re proud to use our network of smart chargers to help balance the grid”, says Arjan Keizer, Chief Strategy Officer at NewMotion. “Our licence from TenneT unlocks the value of smart chargers and EVs as previously unutilised and distributed energy assets. Using the existing charging infrastructure and EV-battery capacity is a material step in the energy transition.”

    Due to the strict requirements, not many companies have the necessary technology to deliver FCR. Keizer continues: “Yet, with our charging technology that simultaneously optimises the charging sessions of thousands of EVs, NewMotion is demonstrating that smart charging is both an effective and a more sustainable way to balance the grid.”

    Maarten Abbenhuis, COO at TenneT: “TenneT envisions a future in which EVs are a relevant element in the solution space that is needed to balance the grid. That’s why we started a pilot project with several market parties, including NewMotion, to identify if and how they could contribute to secure a stable European frequency (50 Hz) via a market based system. We’re excited to see that this pilot now results in the successful certification of NewMotion for grid balancing services. The market entry of new parties using decentralized assets can lead to a more competitive market and resilient energy system by leveraging the level playing field for different types of technologies.”

    Optimised smart charging

    Smart charge points can be used to plan charging sessions and influence charging speeds, optimally spreading the energy charged by EVs over time: both to the EV owner’s and the grid’s benefit. NewMotion, in collaboration with technology supplier Enervalis, uses the charging speed as a buffer to respond to frequency deviations: when the frequency is too low, charging slows down and when the frequency is too high, charging speeds up. Thanks to its smart charging algorithm, EV owners are still ensured of a full charge when they need it. By connecting just 4,000 EVs to the grid NewMotion is able to provide 1 MW for grid balancing services. NewMotion customers can opt-in to the new grid balancing feature as the company will make it available to its existing network of smart chargers.

    About NewMotion

    NewMotion is a leading smart charging solutions provider for electric vehicles, offering smart charging solutions for business and private customers, at the workplace, at home and on-the-go. NewMotion’s mission is to enable everybody to drive as many kilometers as possible powered by clean energy.

    news-2387 Thu, 10 Jun 2021 08:00:00 +0200 Forecast congestion management grid section Friesland https://www.tennet.eu/tinyurl-storage/detail/forecast-congestion-management-grid-section-friesland/ TenneT expects structural congestion, as referred to in Article 9.5 of the Electricity Grid Code, in the western and southern part of 110 kV Friesland grid during the period 2021-2028.  TenneT expects structural congestion, as referred to in Article 9.5 of the Electricity Grid Code, in the western and southern part of 110 kV Friesland grid during the period 2021-2028. 

    The expected congestion is caused by the growth of solar and wind production in the grid of the regional grid operator (Liander) and TenneT. The resulting higher transmission demand cannot be fully facilitated due to the limited available transmission capacity in the high-voltage grid. 

    What is the contracted and available transmission capacity?

    The congestion area concerns the 110 kV stations Gorredijk, Heerenveen, Herbayum, Leeuwarden, Lemmer, Louwsmeer, Marnezijl, Oosterwolde, Oudehaske, Rauwerd, Schenkenschans, Sneek and Wolvega. In the mentioned congestion area, the total contracted transmission capacity is about 1500 MW. The total available transmission capacity is approximately 980 MW. This capacity is completely forgiven in signed bids for contracted transmission capacity. There are no restrictions with regard to consumption.

    The planning of the grid reinforcement

    The structural solution consists of adjusting and reinforcing the Frisian 110 kV grid and increasing the 220/110 kV transformer capacity.

    Research

    TenneT is conducting research into the possibility of applying congestion management in the area mentioned above in accordance with the Grid Code Electricity article 9.5 section 5.

The high-voltage substations and connections in this area have reached the maximum limit of what can be transported.  In the south and west of Friesland the limit for feeding electricity back to the national high-voltage grid has been reached. The high-voltage substations and connections in this area have reached the maximum limit of what can be transported. 

    TenneT will invest a quarter of a billion euros in the coming years to increase the capacity of the grid. At the same time, the national grid manager will start an investigation into the possibilities of creating more connection space with other solutions. This emerges from a formal notification made today to the ACM, the regulator of the energy market.

    The rapid growth of wind and solar parks in Friesland together provide a large amount of sustainable energy, which is by no means all consumed in the province. Throughout the province, 1800 megawatts of sustainable generation have now been developed or are in preparation. This leads to bottlenecks on the grid in the west and south of Friesland, where approximately 1500 megawatts of renewable generation are located. TenneT will structurally resolve these bottlenecks by means of reinforcements, including the installation of additional transformers and adjustments to the regional high-voltage grid. The expected expansion will take place in phases and is expected to last between three and seven years.

    Understanding the plans as early as possible

    Robert Kuik, TenneT Manager of Grid Planning: "In Friesland there are plenty of plans for sustainable energy production, which continue to develop at a rapid pace. All these developments require adjustments to the high-voltage grid. For TenneT it is crucial to know when and where the plans will come as specifically and as early as possible, because expansion of the high-voltage infrastructure takes a lot of time. At the same time we are also looking at other solutions to realise more connection space in the shorter term in order to facilitate the Frisian ambitions from the Climate Agreement in a timely manner."

    TenneT invests 250 million euros in grid reinforcement in Friesland

    TenneT will continue to invest in Friesland over the next few years. In addition to installing additional transformers at the connection stations with the national electricity highway, various grid upgrades will also be carried out. For example, TenneT intends to modify the existing connection between Oosterwolde and Oudehaske so that more electricity can be transported. Windpark Fryslan was already connected this spring, now with a direct cable connection to Oudehaske, and later via a new high-voltage substation to be built near Bolsward. TenneT is also working on initial expansions of the Louwsmeer high-voltage substation and installing additional capacity at the Oudehaske substation. Total investments amount to a quarter of a billion euros.

    Research into congestion management

    If structural bottlenecks occur in the electricity network, the grid manager will also start a formal investigation, based on laws and regulations, into the possibilities of applying congestion management. This is a method based on the electricity market to create more connection space and at the same time prevent overloading of the electricity network. The results of this study are expected in the second half of 2021.

  • A pilot project plans to answer questions such as how decentralised energy producers, consumers and storage systems can alleviate bottlenecks in the power grid
  • Virtual platform brings together and manages test customers
  • Integration of decentralized plants via Equigy Crowd Balancing Platform involves citizens directly in the energy transition
  • Bayreuth/Munich, 1 June 2021. The transmission system operator TenneT and GreenCom Networks ("GreenCom ") are undertaking a field trial to test ways in which decentralised energy producers, consumers, and storages can be integrated to prevent bottlenecks in the transmission system (congestion management) and to balance out fluctuations in power generation and consumption (balancing power). To this end, GreenCom will consolidate the control of smart devices (such as heat pumps and electric cars) of test customers on the company's own platform and then offer these capacities on the Equigy Crowd Balancing Platform. From there, the transmission system operator TenneT can call them up if necessary. This flexibility potential from the smallest installations in households can help to reduce or prevent bottlenecks in the power grid. In this way, the GreenCom test customers can actively participate in the energy transition and benefit economically through the offered flexibility of their installations.

     

    Optimisation of decentralised plants for congestion management

    The special feature of the pilot project is that GreenCom will contribute a large variety of flexibility options. These include not only battery storages and charging stations for electric battery cars but also heat pumps, night-storage heaters, and photovoltaic systems of different manufacturers.

    One objective of the pilot project is to better understand the processes from the transmission system operator down to flexibility providers. To this end, the decentralised installations will be integrated into the virtual power plant developed by GreenCom. The requirements of the test customers (e.g., a fully charged electric car in the morning) can therefore be matched to the requirements of the transmission system. If corresponding requirements exist, the operation of the decentralised installations can be optimised so that bottlenecks in the power grid can be reduced and limitations on the feed-in of renewable power can be minimised or prevented. The blockchain-based Equigy Crowd Balancing Platform developed by a consortium of European transmission system operators will be used as the interface with TenneT's congestion management. The project is initially designed for twelve months and will then be evaluated intensively.

     

    Background

    The development of renewable energy increasingly leads to decentralised structures in the German secondary energy distribution system. The number of small producers, storage systems and consumers will therefore increase massively in the coming years. At the same time, the high feed-in of volatile renewable energy leads to transport bottlenecks in the transmission system. In the future, increasingly less conventionally generated power from large power plants will be available to control these grid congestions and balance out fluctuations in power generation and consumption.

    Intelligently networked and integrated into the system service markets, the flexibility potential of millions of decentralised producers, storages and consumers can make a significant contribution to controlling the power grids.

     

    Use of blockchain-based technology

    The provision of system services for the operating reserve market and congestion management from millions of individual installations requires a new approach to automated control and integration in the transmission system operators' processes and technical solutions by the device manufacturers. TenneT has therefore developed a cross-border blockchain-based data platform – the Equigy Crowd Balancing Platform- with a range of European transmission system operators. This platform will make it easier for millions of households in Germany and elsewhere in Europe to actively offer the flexibility of their installations, through electricity providers and manufacturers, to the system service markets for the stabilisation of the power grid. The Equigy platform enables the automated integration and control of these installations in the processes of the grid operators and market players.

    news-2373 Mon, 31 May 2021 12:00:00 +0200 SuedOstLink: Orders placed for converters near Landshut and Magdeburg https://www.tennet.eu/tinyurl-storage/detail/suedostlink-orders-placed-for-converters-near-landshut-and-magdeburg/ 50Hertz and TenneT’s direct current project reaches important milestone Siemens receives order for converter stations
  • 50Hertz and TenneT’s direct current project reaches important milestone
  • Siemens receives order for converter stations
  • Bayreuth/Berlin, 31 May 2021 – The SuedOstLink direct current (DC) connection, a major grid development project which will enable the energy transition in Germany, is now one step closer to being realised. 50Hertz and TenneT, the two transmission system operators developing the connection, have placed an order with Siemens for the construction of the converter systems which will link both ends of the connection to the existing alternating current grid. 50Hertz is responsible for the part of the SuedOstLink which will run from Saxony-Anhalt to the Bavarian border, whereas TenneT is responsible for the section which will run through Bavaria.

    Both transmission system operators launched a joint call for tenders for the two converters, as they form a single technical unit. Having won the contract for the tender, Siemens will deliver both converter systems to the project developers.

    ‘The placement of the order for the converter systems brings us a good deal closer to the realisation of this power link that is so important for the energy transition,’ said Tim Meyerjürgens, COO of TenneT. ‘TenneT already has many years of experience in laying underground DC cables on land and at sea, as well as in the secure operation of these systems,’ Meyerjürgens continued. ‘The SuedOstLink converter will be the 29th converter in our grid.’

    ‘The SuedOstLink is a decisive step in achieving our objective of integrating 100% of renewable energy into our grid and system by 2032,’ said Dr Frank Golletz, CTO at 50Hertz. ‘After the placement of the order for the SuedOstLink underground cables in May 2020, this is the second important order we have carried out for project.’

    The site for the northern converter in 50Hertz’s area has already been determined: it will be built at the Wolmirstedt substation to the north-west of Magdeburg. Certain systems belonging to the existing substation can be used for the new project. Moreover, the substation is the most connected central grid node in the north-east of Germany, where high amounts of wind power are produced.

    The southern converter in Bavaria will be constructed in the Landshut area, near the Isar grid connection point. TenneT is currently exploring four potential converter sites based on a scoping study published in October 2020 by the Federal Network Agency, which is responsible for granting the construction permit for the project. The Agency has the ultimate say about the site for the converter; it will publish its decision regarding the site at the same time as its decision about whether or not to grant planning approval for the project.

    The converter systems each require a surface of approximately 4.5 hectares in order to be built. The entire construction phase, including commissioning, is expected to take three and a half years. The costs for both converter systems amount to several hundred million euros. The total cost of the SuedOstLink is around four to five billion euros.

    Converters are needed to transform alternating current into direct current and vice versa. In order to transport the alternating current generated by wind turbines in the north and east of Germany to the densely populated areas and industrial centres in southern Germany (whilst minimising losses), it is converted into direct current at the northern converter station and then converted into alternating current again at the southern converter station.

    The SuedOstLink project, alongside the process for awarding the contracts for both converter systems, was outlined in the Federal Requirements Plan Act (Bundesbedarfsplangesetz, BBPlG). The most recent amendment to this Act (carried out by the Bundestag and Bundesrat) specified that the SuedOstLink should be expanded to include another direct current system with an additional transmission capacity of 2 gigawatt. This project (known as Project 5a) will run from the Klein Rogahn area (to the west of Schwerin) to the west of Magdeburg (in the Börde district) and along the SuedOstLink route. One converter in Klein Rogahn to the west of Schwerin and one in the Isar area are required for project 5a. Another call for tenders for the construction of these additional pieces of infrastructure is due to be launched soon.
