News: TYPO3 News Sun, 14 Aug 2022 00:10:06 +0200 Sun, 14 Aug 2022 00:10:06 +0200 TYPO3 EXT:news news-2721 Tue, 09 Aug 2022 12:57:58 +0200 Bidding Zone Review: TSOs investigate alternative bidding zone configurations https://netztransparenz.tennet.eu/tinyurl-storage/detail/bidding-zone-review-tsos-investigate-alternative-bidding-zone-configurations/ In the context of the European Electricity Regulation, part of the Clean Energy Package, the European Transmission System Operators (TSOs) for electricity have to conduct a common study into alternative bidding zone configurations, the so-called Bidding Zone Review. Bidding zones are areas in Europe in which a single (wholesale) electricity market price applies. On the 08th of August, the European regulatory authority ACER has taken a decision that for France, Germany, Italy, the Netherlands and Sweden, alternative bidding zone configurations have to be investigated in the Bidding Zone Review. Germany is clearly the focus of the Bidding Zone Review: Here, four different alternative configurations must be investigated, while for each of the other countries mentioned only one alternative configuration will be studied. In the context of the European Electricity Regulation, part of the Clean Energy Package, the European Transmission System Operators (TSOs) for electricity have to conduct a common study into alternative bidding zone configurations, the so-called Bidding Zone Review. Bidding zones are areas in Europe in which a single (wholesale) electricity market price applies. On the 08th of August, the European regulatory authority ACER has taken a decision that for France, Germany, Italy, the Netherlands and Sweden, alternative bidding zone configurations have to be investigated in the Bidding Zone Review. Germany is clearly the focus of the Bidding Zone Review: Here, four different alternative configurations must be investigated, while for each of the other countries mentioned only one alternative configuration will be studied.

Given the high level of congestions within Germany and the Netherlands, TenneT supports ACER’s decision to investigate the effects of bidding zone splits for Germany and the Netherlands. TenneT will actively contribute to delivering objective and representative results such that in the end involved Member States can make a well-informed decision on the future bidding zone configuration for Europe.

Why investigate alternative bidding zone configurations?

The purpose of the Bidding Zone Review is to investigate whether alternative bidding zone configurations increase the economic efficiency and cross-zonal trade opportunities, without jeopardising the operational security of the electricity grid. Regulation (EU) 2019/943 on the internal market for electricity ("EU Electricity Regulation") prescribes that bidding zone borders should be based on structural congestions in the transmission grid.

When drafting the methodology for the Bidding Zone Review in 2019, TSOs also had to propose alternative configurations to be studied for the Review. At that time, TenneT together with the German TSOs, suggested to study alternative configurations for the Netherlands and Germany, including a split of the Dutch bidding zone in three zones and three different splits of the Germany bidding zone. However, as the NRAs could not agree to approve the proposal, the decision on the methodology, assumptions, and alternative bidding zone configurations to be considered in the Review process was transferred to ACER on 13th July 2020.

ACER concluded that they did not yet have sufficient information to decide on the alternative configurations which should be evaluated. As a way forward, in November 2020 ACER tasked the TSOs to calculate so-called Locational Marginal Prices (LMPs) – essentially a nodal price per substation – for the target year 2025. Last March, the TSOs achieved a significant milestone with the completion of these LMP calculations for the whole of continental Europe, and submitted these results to ACER. The results have also been made publicly available on ENTSO-E’s website.

Based on these results, ACER has now adopted a decision on which alternative bidding zones have to be investigated in the Bidding Zone Review. With this decision, the Bidding Zone Review can now commence.

The alternative bidding zone configuration to be investigated for The Netherlands

The Netherlands is currently one single bidding zone. ACER has decided that for the Netherlands, a split into two separate bidding zones has to be investigated. The bidding zone split roughly follows the border between the province of Overijssel and the province of Gelderland, where all network elements to the 110 / 220 kV would end up in the north-eastern Bidding Zone and all 150 kV network elements would end up in the south-western Bidding Zone.

 

Figure 1: The to-be-studied alternative bidding zone configuration for the Netherlands

The alternative bidding zone configurations put forward for Germany

Germany and Luxembourg together currently form a single bidding zone as well. For Germany, four individual alternative bidding zone configurations have to be investigated: two different splits in two bidding zones, one split in three bidding zones, and one split in four bidding zones.

 

Figure 2: The to-be-studied alternative bidding zone configurations for Germany

The alternative biding zone configurations in figures a) and b) show a North-to-South split. In figure a), the bidding zone delineates slightly further southwest than in figure b). The configuration of figure c) foresees an additional split of the northern biding zone into a western and eastern zone. Figure d) shows a split into four bidding zones, in which the southern bidding zone is further divided and the Eastern bidding Zone further extended to include also Schleswig-Holstein.

Next to the individual configurations, where a split of one bidding zone in isolation will be studied, meaning that all other BZs are simulated with the status quo configuration, two combinations which each comprise two member states will be studied. These combinations will be determined during the process by combining the individual configurations which are estimated to entail the highest individual monetised benefits.

A wide range of indicators will be studied in the Bidding Zone Review

The Bidding Zone Review will include an extensive evaluation of the positive and negative effects of different bidding zone configurations. In total, 22 indicators related to overall market efficiency, network security, stability & robustness of the bidding zones, and effects on the energy transition will have to be assessed. With the output of these 22 indicators, the TSOs will conduct the evaluation process as established by the Bidding Zone Review methodology, in order to finally come up with a joint recommendation for each region on whether to keep the current bidding zone configuration, or amend it.

Stakeholder input is essential for the Bidding Zone Review

Stakeholder expertise is essential for any discussion of a fundamental market design element such as the bidding zone configuration. ENTSO-E and the TSOs strive to involve a wide range of stakeholders from the start of the Bidding Zone Review process, with substantial consultation during the review via public workshops, an inquiry on transition costs and a public consultation. Also, a Bidding Zone Review Consultative Group has been established, where Dutch and German market parties are being represented by European associations, as well as national bodies including Energie-Nederland and BDEW. TenneT encourages interested Dutch and German stakeholders to let their voice be heard via these associations and to make use of the consultation possibilities during the review such that their views on the effects of alternative bidding zone configurations can be taken into account during the Review process.

Bidding Zone reconfigurations are not expected to happen before 2027

On the basis of the results of the study, which is expected to be completed in 2023, TSOs will make a joint recommendation to the governments of the involved member states. The member states will then have six months to decide unanimously whether to maintain or amend the current bidding zone configuration, and when this change should take effect. Given the time required to enable all parties in the energy sector to prepare and adapt their systems to make this possible, it is not expected that a bidding zone reconfiguration would be implemented before 2027.

news-2718 Mon, 08 Aug 2022 08:00:00 +0200 Sail-out completed: TenneT’s 900 MW offshore platform DolWin kappa leaves shipyard in Cádiz https://netztransparenz.tennet.eu/tinyurl-storage/detail/sail-out-completed-tennets-900-mw-offshore-platform-dolwin-kappa-leaves-shipyard-in-cadiz/ After just three years under construction, the offshore converter station is now on its way to the North Sea.DolWin kappa is part of the DolWin6 grid connection system, which is scheduled to be commissioned in 2023. The 900 MW connection will supply more than 1 million households with green wind power from the German North Sea. 
  • After just three years under construction, the offshore converter station is now on its way to the North Sea.
  • DolWin kappa is part of the DolWin6 grid connection system, which is scheduled to be commissioned in 2023.
  • The 900 MW connection will supply more than 1 million households with green wind power from the German North Sea. 
  • TenneT will soon be reliably bringing even more green wind power from the German North Sea to land via the direct current connection DolWin6. Europe’s leading offshore transmission system op-erator has now reached the next important milestone on its path to this objective: the sail-out of the 900 MW offshore platform DolWin kappa, which took place on 5 August 2022 from the Dragados Offshore shipyard in Cádiz, Spain. After only three years of construction, the platform is now on board the transport barge “Iron Lady” and on its way to the Dutch port of Rotterdam. There, it will be reloaded onto the world’s largest service vessel, the “Pioneering Spirit”, and then shipped to the installation site. The grid connection system is scheduled to be commissioned in 2023 and provide renewable energy to over 1 million households. 

    “TenneT is taking its mission seriously and advancing the grid expansion in the North Sea step by step. With the successful sail-out of the offshore platform DolWin kappa, we have taken the next important leap. DolWin6 is already the 13th offshore grid connection in our German portfolio and will bolster Europe’s urgently needed energy independence beginning in 2023,” said TenneT COO Tim Meyerjürgens when the platform set sail. “We also have our partners to thank for the fact that we are reaching this milestone on schedule. Working closely with our contractors Siemens Energy and Dragados Offshore, my colleagues took only three years to build the platform despite the enormous challenges posed by the pandemic. This is an outstanding achievement – and proof that we have strong, reliable partners,” Meyerjürgens added. 

    The platform consists of a foundation structure (jacket) and a superstructure (topside). The two have a combined height of about 82 metres, so the platform will rise about 53 metres above the surface of the North Sea. In addition, there will be a bridge that will connect DolWin kappa with DolWin beta (grid connection system DolWin2), which was already commissioned in 2016, in order to efficiently use the already existing infrastructure of the parent platform. What’s more, the overall optimised design of the platform has significantly reduced the size of DolWin kappa. “The well-thought-out construction of the offshore platform conserves important resources while minimising impacts on the environment. This clearly illustrates that protecting the environment and nature is our top priority when planning and implementing our grid connections,” Tim Meyerjürgens said. 

    Once it arrives in Rotterdam, the platform will be reloaded onto the world’s largest service vessel. The 382-metre-long “Pioneering Spirit” will carry all platform components (jacket, topside, piles and bridge) to their final destination in the German North Sea. Once there, DolWin kappa will be installed directly from the work boat. After the platform is commissioned in 2023, it will convert the alternating current generated by offshore wind farms into direct current, which will then be transmitted to Hilgenriedersiel on the mainland via an approximately 45-kilometre-long subsea cable. From the landfall in Hilgenriedersiel, the electricity will be transmitted to Emden by a land cable, which will also be 45 kilometres long. Here on land, TenneT has built the Emden/Ost converter station and transformer station to convert the direct current back into alternating current and then feed it into the high-voltage grid at the correct voltage level.

    news-2706 Fri, 29 Jul 2022 09:30:00 +0200 EUR 1.6 billion of grid investments for carbon neutral future amid strong focus on energy security https://netztransparenz.tennet.eu/tinyurl-storage/detail/eur-16-billion-of-grid-investments-for-carbon-neutral-future-amid-strong-focus-on-energy-security/ In the first half of 2022 within a complex and unpredictable external environment TenneT continued its strong efforts to drive the energy transition, investing EUR 1.6 billion in the grid and once again maintaining a high grid availability of 99.999%. Underlying revenue increased by EUR 2,407 million to EUR 4,975 million.  In the first half of 2022 within a complex and unpredictable external environment TenneT continued its strong efforts to drive the energy transition, investing EUR 1.6 billion in the grid and once again maintaining a high grid availability of 99.999%. Underlying revenue increased by EUR 2,407 million to EUR 4,975 million. 

    This was mainly due to increased compensation of grid-related expenses and the increased asset base. The underlying operating result increased by EUR 148 million to EUR 579 million. With energy security in the spotlight as never before, TenneT is focusing on both short-term and long-term solutions to deliver on its critical task: ensuring the continuous availability of electricity for nearly 43 million end-users across the Netherlands and Germany.

    Short term: impact and focus on security of supply
    The Ukraine war - a humanitarian, geopolitical and security crisis - has had a notable impact on TenneT’s activities. In the European ENTSO-E context TenneT has collaborated to synchronize the Ukrainian and Moldovan grids with the European grid to support electricity supply in those countries. The Ukraine war has also exacerbated rises in energy prices, as well as a strong awareness of the importance of security of supply. To this end, TenneT is seeing companies accelerating their electricity demand and governments becoming more proactive and ambitious in bringing about the energy transition. Both the Ukraine war and the COVID-19 pandemic have had a major impact on the prices of the raw materials TenneT uses in its assets. This includes steel, aluminium and copper. High market price-levels of energy have also led to a significant increase in grid expenses. These are costs TenneT must incur to compensate for grid losses, to maintain the energy balance on the grid, and to pay for alternative routes for the electricity when grid sections are congested or unavailable due to grid expansions. Under regulatory rules, these higher grid expenses are budget neutral and will be reimbursed through future tariffs.

    The electrification drive among companies and industries and the fast-growing demand for electricity - including renewables - led to capacity issues (congestion) on TenneT’s grids in certain regions. This became most evident in the Dutch provinces of Noord-Brabant and Limburg where a temporary stop is set for new connection requests pending a congestion analysis. TenneT, in close cooperation with all stakeholders - such as the Ministry of Economic Affairs & Climate and the designated coordinator - is working hard on congestion solutions for these provinces and more broadly. There are four elements to this approach, with different responsibilities and varying degrees of involvement for the stakeholders involved. These are: making smarter use of the grid, speeding up grid expansions, increasing predictability through a more programmatic approach, and improving communications.

    Mid/Long term: preparing now for a carbon-free energy system
    Firstly, the innovative 2GW program will enable the faster development of offshore wind energy through economies of scale and the standardisation of 15 up to 20 2GW offshore wind connection systems by around 2030. The 2GW standard represents a huge step forward after today’s 0.7GW AC and 0.9GW DC offshore-connection systems. It will save time, resources and money, while doubling connection capacity by using fewer cables and platforms. TenneT plans to enter into a cooperation agreement with key market partners for a period of up to eight years. The agreement covers offshore platforms and onshore stations, as well as the converters for the two-way conversion between alternating and direct currents. The impetus of the large-scale tender underlines the long-term purpose of building up all the required resources such as industry sites, staff, and materials.
    Secondly, TenneT has taken the first steps toward what it calls the Target Grid 2045. In close coordination and dialogue with governments, ministries, and other stakeholders, TenneT aims to design and build the electricity grid of the future. This must ultimately be ready by 2045. With Target Grid, TenneT is committed to making a timely and active contribution to the forward-looking path taken by the Dutch and German governments towards an affordable and achievable highly electrified climate-neutral energy system.

    Manon van Beek, CEO TenneT, says: “Just as collaboration across countries is key to working on the Target Grid, the same is true for achieving energy security this winter. We’re all giving this our full attention right now. The tendency to focus too closely on our national interests doesn’t produce the right solutions. To become independent from Russian gas, and from fossil fuels in general, I believe we must become more dependent - on each other that is. This applies to the EU member states, but also to politics and industry, citizens and customers, suppliers and producers, regulators and TSOs. The recent Esbjerg Offshore Wind Declaration – through the Netherlands, Germany, Denmark, and Belgium agreed to jointly develop the North Sea as the green power plant of Europe - is a striking example of the kind of collaboration we need.”
    Arina Freitag, CFO TenneT, says: “As a true cross-border TSO, we can really make a big and positive impact on Europe’s transition to a green energy system, assuming green growth is smart and  responsible. This means, for example, that regulations and the granting of permits must keep pace with the implementation of our investments. Furthermore, I expect that our current investment programme will require additional funding with both debt and equity capital. Sharp price increases for materials and other resources are at the root of the increasing costs of our projects. This will also have an impact on grid tariffs for consumers and businesses.”

    Key accomplishments first half year 2022

    In the first half of 2022, we made significant progress on several projects, most significantly:

    • In the Netherlands, offshore grid Hollandse Kust (zuid) Alpha and Beta - TenneT’s high voltage connections for offshore wind farms Hollandse Kust (zuid) - are ready for use. When fully commissioned in 2023, the 1,400MW wind farm area will generate green electricity equal to the annual consumption of more than two million households. Hollandse Kust (zuid) consists of an onshore high-voltage station, offshore cables and two offshore high-voltage alternating current transformer stations, located about 20 kilometres off the coast of The Hague.
    • In Germany, TenneT delivered a new 61 kilometres long high-capacity 380 kV power line between Emden and Conneforde. This new connection can transmit three-and-a-half times as much electricity as the previous one. It will primarily transport and distribute wind power from the North Sea. Onshore grid projects like this one are critical to the vision outlined in the Esbjerg Offshore Wind Declaration.
    • In May TenneT issued a EUR 3.85 billion green bond. Having issued a total of around EUR 17 billion of green debt confirms the company's ease of access to capital markets.  
    • Long-term senior unsecured credit ratings for TenneT Holding B.V. remained unchanged during the first half of 2022 and were reaffirmed by both Standard & Poor’s (A- / stable outlook) and Moody’s Investor Service (A3 / stable outlook) in April.

    news-2692 Tue, 05 Jul 2022 15:00:00 +0200 Offshore grid connection BorWin6: TenneT awards contracts for cable https://netztransparenz.tennet.eu/tinyurl-storage/detail/offshore-grid-connection-borwin6-tennet-awards-contracts-for-cable/ The contract for production and installation of the DC cables at sea and on land is awarded to Nexans Norway AS235-kilometre-long direct current connectionCommissioning of the 980 megawatt connection is scheduled for 2027
  • The contract for production and installation of the DC cables at sea and on land is awarded to Nexans Norway AS
  • 235-kilometre-long direct current connection
  • Commissioning of the 980 megawatt connection is scheduled for 2027
    • In the tendering process for the award of the contract to build the 235-kilometre-long offshore grid connection system BorWin6, TenneT has now also awarded the contract for cable pro-duction and laying. Nexans will be the contractor for the sea, tidal flat and land cables. This means that the important contracts for the construction of the BorWin6 grid connection have been awarded. TenneT had already commissioned the converter stations at sea and on land in February.

      "We have a long and trusting partnership with Nexans, which guarantees us reliability and quality at the same time," said Tim Meyerjürgens, COO of TenneT. BorWin6 is the last grid connection project in the German North Sea to be realised by TenneT before the technologi-cal leap to two gigawatts and 525-kilovolt cables.

      Various direct current cables with 320 kilovolts will be used in the project. Among other things, about 400 kilometres of cables with copper conductors, which have a diameter of up to about 14 centimetres, will be produced for laying at sea, including reserve cables. They weigh about 47 kilogrammes per metre. On land, cables with an aluminium conductor are also used, which weigh 16 kilograms per metre with a diameter of 12.5 centimetres. In sections of about 1,400 metres, these will then be connected to each other with sleeves. The laying work is scheduled to start in 2025.

      Two cable strings will be laid for the grid connection, one positive and one negative pole, as well as an additional fibre optic cable, which will later be important for controlling the system.

      The wind turbines are connected directly to the BorWin kappa offshore platform via innovative 66-kilovolt three-phase cables. This eliminates the need for the transformer stations that were previously required in each wind farm and the 155 kV three-phase cables that were previously used to connect to TenneT's offshore platform.

      Using the extra-high voltage direct current cable, which is 235 kilometres long in total, TenneT transmits the electricity to the converter station in Büttel (Schleswig-Holstein) on land after conversion using low-loss direct current technology. Here, the direct current is converted back into three-phase current and fed into the extra-high voltage grid.

       

      With the innovative 66 kV connection, the wind farms are directly connected to TenneT's offshore platform. Transformer stations in the offshore wind farms are thus no longer necessary.

       

      Facts and figures on BorWin6

      BorWin6 will be realised with a capacity of 980 megawatts off the coast of Borkum. With 190 kilometres of submarine cable, it will be the longest submarine cable route to date. On land, the cable will be laid parallel to the existing routes of the HelWin1+2 and SylWin1 connec-tions, whose onshore converters are also located in Büttel.

      • 235 kilometres long connection using high-voltage direct current transmission technol-ogy (HVDC) with a maximum transmission capacity of 980 megawatts
      • 45 kilometres of land cable, 190 kilometres of submarine cable
      • Grid connection point: Büttel (Schleswig-Holstein)
      • Planned commissioning 2027

      Hollandse Kust (zuid) Alpha and Beta, TenneT’s high voltage connections for offshore wind farms Hollandse Kust (zuid) I and II are ready for use. TenneT completed the installation and energization of the offshore Beta grid connection; the Alpha grid connection was already completed in March. Wind farm developer Vattenfall can now connect the wind turbines to the high voltage grid. Today TenneT, together with stakeholders and contractors, celebrated this significant milestone during the Net op Zee event at the Hollandse Kust (zuid) land station on the Maasvlakte.

      Hollandse Kust (zuid), or HKZ in short, connects the wind farm area with the same name – located approximately 20 kilometers off the coast of The Hague – to the Dutch mainland. Developed by Swedish energy company Vattenfall and owned by Vattenfall, BASF and Allianz, the 1400 MW HKZ windfarm will become world’s largest and 1st subsidy free offshore wind projects when it’s fully commissioned in 2023.

      Partnering for the energy transition

      The wind farm area will generate green electricity equal to the energy used by one and a half million households annually. Manon van Beek, CEO TenneT: “The significance of this is huge: wind energy is a major driver of the energy transition, and we’re proud that TenneT’s work is contributing to a sustainable future. But we’re just one player in the complex process of making the energy transition happen. The task ahead of us is enormous and partnering with other parties in the chain is crucial to reach our future targets.”

      “Power sockets at sea”

      Hollandse Kust (zuid) consists of a land station, sea cables and two High Voltage Alternating Current (HVAC) transformer stations, located about 20 kilometres off the coast of The Hague. These transformer stations can be considered as “power sockets at sea”, to which Vattenfall’s wind farm area can be connected in order to bring the wind energy to the mainland. During the Net op Zee event Vattenfall CEO Martijn Hagens and Manon van Beek, performed the symbolic and ceremonial act of plugging together the Offshore wind farm with the onshore grid.

      “Wind energy, both onshore and offshore, is one of the cornerstones to reach our ambition of a fossil free living within one generation. Connecting Hollandse Kust Zuid with its customers is a big milestone for our project, especially given that we expect first power any time soon. We congratulate the offshore division of TenneT with this success,” says Martijn Hagens, CEO of Vattenfall in the Netherlands.

    • Achieving offshore targets requires new tender approach– novel framework agreement offers growth opportunities for technology companies and transmission system operators alike
    • Set goals: investment security, employment, and developing the required resources and supply chains
    • TenneT to connect 40 gigawatts of offshore expansion in the German and Dutch North Sea
    • In the Esbjerg Declaration in May at the North Sea Energy Summit, Germany, the Netherlands, Denmark, and Belgium agreed to jointly install at least 65 gigawatts of offshore wind energy by 2030. Transmission system operator (TSO) TenneT will account for almost two-thirds of this with 40 gigawatts - 20 gigawatts each in the German and Dutch North Seas. Achieving these offshore targets requires a new tender approach to ensure that the supply chain is able to anticipate on necessary investments.

      Stimulate market with framework agreement

      TenneT COO Tim Meyerjürgens said: "In order to meet the challenges posed by this major expansion target and achieve its goals, we are breaking new ground in cooperation with our industry partners, sending a strong signal to the market with a large-scale tender. The goal is to set out a new kind of framework agreement that allows for scaling through efficiently expanding these new offshore systems - both for technology companies and for other transmission system operators. This will stimulate the market to build up the resources and comprehensive supply chains we need in a targeted and – crucially – in faster way. In these turbulent times this provides the industry with the investment security they need."

      TenneT plans to enter into a cooperation agreement with key market partners for a period of up to eight years. The agreement covers offshore platforms and onshore stations, as well as the converters for the two-way conversion between alternating and direct currents. The latter is based on the innovative 2-gigawatt high-voltage direct current technology for a forecast 15 to 20 offshore grid connection systems. Total order volume is estimated to be up to 30 billion euros.

      The impetus of the large-scale tender sends a strong signal to the market. It underlines the long-term purpose of building up all the required resources such as industry sites, staff, and materials. Whereas up to now individual projects have always been tendered consecutively, the entirety of this large-scale tender will provide the market with the investment security and planning acceleration it needs.

      Accelerated expansion offers growth opportunities and strengthening of supply chains

      "The accelerated expansion of renewable energies offers many opportunities. To take advantage of them, strong cooperation is necessary at all levels. This ground-breaking cooperation framework enables more flexibility, technological progress, and planning security for market players. It also shows which innovative solutions we are working on with the market to help us tackle and implement the expansion targets set by the governments in a targeted way. Our new approach will stimulate and drive the entire market across the value chain, allowing us to attract new industrial companies and help create new jobs. This benefits all parties through more employment, growth, and the strengthening of European supply chains," Tim Meyerjürgens added.

      Background / 2GW Program

      Currently, TenneT’s offshore connection capacity comprises around 7.2 gigawatts in the German North Sea and approximately 2.5 gigawatts (GW) in the Dutch North Sea. TenneT's innovative 2GW Program is crucial in managing the offshore energy transition and will help Europe become the world's first climate-neutral continent. This new standard combines our extensive expertise in offshore grid connections with a unique transnational approach. With its strong focus on harmonisation and standardisation, it provides a blueprint for future offshore grid connection systems and enables faster deployment. At the same time, the larger capacity of two gigawatts per system reduces the number of grid connections required. The 2GW Program sets a new pace for the European energy transition. It will provide Europe and its inhabitants with more green energy in a safe and cost-effective way - with the lowest possible environmental impact.

TenneT expects the ongoing congestion management studies to be completed as of September. The various studies are in full swing and extensive market consultations are currently taking place. The current studies take into account the latest insights from the new Grid Code, which was published by the ACM last week.

       

      Last year TenneT announced congestion studies for Brabant-Limburg, Friesland and Flevoland-Gelderland-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. With congestion management, in which flexibility plays an important role, the existing grid can be better utilized and space is created for new initiatives. The application of congestion management is a temporary measure on the way to structural grid reinforcements.

      Studies in progress

      The studies are in progress. They include an assessment of the suitability of the network for application of the system. An extensive market survey is also being carried out in the various areas, looking at parties who can offer flexible power. Part of the market exploration is the recently published consultations. The latest insights from the new Grid Code, which was published by the ACM last week, are also included in the current studies. This new code provides more room for the application of congestion management. Grid managers have six months to implement this.

      TenneT expects these ongoing studies to be completed as of September.

      news-2659 Thu, 19 May 2022 13:00:00 +0200 Ørsted offshore wind farm is the first to supply balancing capacity to German grid https://netztransparenz.tennet.eu/tinyurl-storage/detail/oersted-offshore-wind-farm-is-the-first-to-supply-balancing-capacity-to-german-grid/ Ørsted's Borkum Riffgrund 1 wind farm is the first German offshore wind farm whose produced electricity is fed into the German electricity grid of transmission system operator TenneT in a system-stabilising manner. Following the successful completion of a pre-qualification process, Borkum Riffgrund 1 demonstrates that balancing services can be offered and fed into the electricity grid. Ørsted's Borkum Riffgrund 1 wind farm is the first German offshore wind farm whose produced electricity is fed into the German electricity grid of transmission system operator TenneT in a system-stabilising manner. Following the successful completion of a pre-qualification process, Borkum Riffgrund 1 demonstrates that balancing services can be offered and fed into the electricity grid.

      Leipzig/Hamburg/Bayreuth. Since May 2022, Ørsted's offshore wind farm Borkum Riffgrund 1 has been providing system-stabilising balancing capacity for the German electricity grid. The companies Energy2market and Ørsted have worked together successfully to make the electricity from Borkum Riffgrund 1 usable as balancing capacity for the German electricity grid. The prequalification specified by the transmission system operator TenneT was granted and the offshore wind farm has shown that short-term grid fluctuations can be balanced with renewable electricity from offshore wind energy.

      Jörg Kubitza, Managing Director of Ørsted in Germany, says: "Today Offshore wind shows, that it is in no way inferior to electricity from conventional power plants. Offshore windfarms produce far more electricity than any other renewable energy source. The technology is also competitive in terms of costs. And now offshore wind is also conquering the area that was previously reserved for conventional energy sources: the stabilisation of the electricity grid. This is why offshore wind is the backbone of the energy transition in Germany, because it contributes to security of supply on many levels." 

      In addition to TenneT, the Energy2market prequalification concept on which the project is based also convinced the other three German transmission system operators and was approved for all four control areas. Offshore wind power is entering additional new territory with Borkum Riffgrund 1 as the first German wind farm ever to also be approved for the provision of particularly demanding aFRR.

      "I am always particularly pleased when we succeed in opening up new attractive business areas for our customers and partners and at the same time make a sustainable contribution to the success of the energy transition. This is clearly the case with Borkum Riffgrund 1," says Raphael Hirtz, Managing Director of Energy2market. "The integration via our virtual power plant in the German balancing energy market now enables Ørsted to market the potential of the offshore wind farm in a way that serves the system. In addition, it is also a milestone in the energy transition. Borkum Riffgrund 1 demonstrates the ability of renewables to compensate for a large part of the reduced flexible output in the overall system due to the phase-out of coal and nuclear power generation."

      TenneT COO Tim Meyerjürgens says: "TenneT has worked intensively with the other transmission system operators to revise the prequalification conditions with the aim of attracting wind farms to provide balancing capacity. This is now possible and thus represents an important step for the integration of wind energy plants into the balancing power market. I thank Ørsted and Energy2market for pioneering this together with us and I am confident that the prequalification of the first offshore wind farm will also motivate other market participants to take this step so that more and more balancing capacity from wind farms can be successfully traded on the German balancing power market in the future."

       

      Balancing services compensate for fluctuations in the electricity grid

      As a result of the energy transition in Germany and the phase-out of nuclear and coal-fired power, more and more conventional power plants are being phased out, some of which used to provide balancing services. In order to avoid a supply gap in the provision of balancing services, the German transmission system operators have made intensive efforts to also prequalify renewable energies such as wind power and photovoltaics. 

      The term balancing service can also be called balancing power or balancing energy. As a reserve, this balances out the fluctuations in the electricity grid, i.e. the electricity grid frequency. The fluctuations in the electricity grid can occur, for example, due to a sudden drop in electricity demand or a change in the weather and thus higher production from wind and solar. The use of balancing services can compensate for these fluctuations and thus ensure that there is still a balance between generation and consumption. Electricity can be fed into the grid as well as taken from the grid.

       

      Why has the prequalification of wind power plants been rare so far?

      For balancing services, in addition to speed in provision, the stability of the power provided is also crucial. With the offshore wind farm (OWF) Borkum Riffgrund 1, a solution was found for this. The OWF adjusts the so-called operating point continuously. The control power provided is determined on the basis of this. For the power frequency controller in TenneT's control room, the OWF therefore looks like a normal conventional power plant. In addition, Energy2market plans exactly how much power is to be marketed for the next day. If the weather forecasts are inaccurate, slightly less power is offered, but it can then be provided safely.

      news-2656 Wed, 18 May 2022 19:00:00 +0200 TenneT calls for acceleration of North Sea cross-border wind for European energy independence and security https://netztransparenz.tennet.eu/tinyurl-storage/detail/tennet-calls-for-acceleration-of-north-sea-cross-border-wind-for-european-energy-independence-and-se/ REPowerEU package highlights need for exceptional measures in the current energy crisis  REPowerEU package highlights need for exceptional measures in the current energy crisis 

      • Achieving ambitious national and international renewable energy targets requires offshore wind developers, policy-makers and grid operators to intensify and accelerate their cooperation.
      • National and European policy makers should create a reliable growth path across borders to  empower investors and to deliver in time.
      • The new national targets for offshore wind power are a huge challenge for the whole supply chain which needs to be prepared for the coming growth.

      CEO Manon van Beek spoke at the North Sea Wind Summit in Esbjerg, Denmark, where Commission President Ursula von der Leyen presented the REPowerEU package to Heads of State from the four North Sea countries. Denmark, Germany, the Netherlands and Belgium world leaders in offshore energy, met to map the way forward.

       

      To reach the new very ambitious climate targets, we need even more cross-border cooperation in Europe’s energy markets. We must use this opportunity today to boost our collaboration, as a group of like-minded partners. Together we can make the North Sea the powerhouse of Europe’s affordable, secure and green energy future. To succeed, we must take a fully international approach to the energy transition, working together with all the North Sea countries,” says Manon van Beek, CEO of TenneT.

       

      Renewable energies, particularly offshore wind power, show their value at this urgent time of need and improve the supply of affordable electricity for European households. The crisis has shown the importance of accelerating the roll-out of offshore wind power in the North Sea for energy security and market stability. The REPowerEU package sets important steps shortening and simplifying permitting processes for the deployment of renewable energy. Grid infrastructure projects should benefit from same acceleration rules as renewable energy projects.

       

      To achieve this acceleration the important elements of the political framework must fit together seamlessly: incentives for renewable generation, market design, security of supply, the building of infrastructure and the strategy for hydrogen. For all this we need a joint strategy. All parts of the system influence each other.

       

      “This conference led by Heads of State shows that developing the North Sea is “Chefsache”  and it is about proving trust – trust in a comprehensive collaboration, trust to overcome thinking in boxes - whether they are geographic or different energy carriers, whether it is sellers or buyers” Manon van Beek said.

       

      Addressing the heads of government in Esbjerg, Manon concluded: “Europe can maintain its leading role in offshore technology – one of the cheapest sources of electricity – if we ensure three things now”:

       

      1.   Set a reliable growth path

      National governments and the EU have it in their hand to counter the current energy crisis by creating a reliable growth path by harvesting offshore wind in the most efficient place in Europe., This needs three commitments offshore: cross-border coordination on locations for new wind parks, roll-out schedules and reliable tendering schemes so everybody is empowered to invest in time.

       

      2.   Speed up cross border cooperation

      The future is an interconnected offshore system that also enables the exchange of electricity between countries and security of supply for all. Such cross-border projects need to be a convincing investment case for everybody, also for offshore wind parks. Technically everything is possible but we also need the right incentives at EU and national level.

       

      3.   Ensure technical interoperability

      High Voltage Direct Current technology is so new that the components of different suppliers do not work together properly. Today it is not possible to connect a converter stations supplied by different manufactures. Together with other companies in the industry TenneT developed a vendor-neutral standard for the next HVDC technology generation. We have urgently asked the EU Commission to support this by approval in short time.

      news-2652 Fri, 13 May 2022 11:59:49 +0200 TenneT awards NRG contract for onshore cable connection of Hollandse Kust (West Beta) project https://netztransparenz.tennet.eu/tinyurl-storage/detail/tennet-awards-nrg-contract-for-onshore-cable-connection-of-hollandse-kust-west-beta-project/ Contractor combination NRG (Denys, Alsema and Van Vulpen) will realise the link between the offshore cables for the wind farm Hollandse Kust (west Beta) and the transformer station in Wijk aan Zee for TenneT. NRG will install 2.5 km of high voltage underground cables from Velsen beach. This will be done by means of underground directional drilling, as used for the Hollandse Kust (north) and (west Alpha) projects. Contractor combination NRG (Denys, Alsema and Van Vulpen) will realise the link between the offshore cables for the wind farm Hollandse Kust (west Beta) and the transformer station in Wijk aan Zee for TenneT. NRG will install 2.5 km of high voltage underground cables from Velsen beach. This will be done by means of underground directional drilling, as used for the Hollandse Kust (north) and (west Alpha) projects.

      The award of this contract marks the continuation of the successful collaboration between TenneT and the consortium of contractors for the connection of offshore wind farms in the IJmond region. NRG is currently carrying out the final drillings from Velsen to complete the cable connection for the three offshore wind farms between the transformer station at Wijk aan Zee and the high-voltage substation along the A9 freeway in Beverwijk.

      Appeal procedure by the Council of State
      The work is expected to start sometime in the autumn of 2023. However, this depends on an ongoing appeal procedure at the Council of State. The hearing will take place on July 7, after which a decision is expected next fall. In order not to lose any valuable time in connecting offshore wind energy, TenneT has received permission from the Ministry of Economic Affairs and Climate Change to award this project component in advance.

      Building on
      This means NRG can start detailed engineering and drawing up work plans. The contractor can thankfully draw on the knowledge and experience of the past year. "We know the area and the people well, we have the know-how and the right equipment, and we have experience of techniques that have proved their worth over the past year,' says project manager Mark de Bruijn on behalf of NRG. "By working for this project we can build on our good relationships with the parties involved in the area."

      Specialist work with an eye for the local community
      TenneT is also pleased with the continued cooperation. Dick Vergoes Houwens, project manager for onshore cable on behalf of the grid operator, said: 'NRG's team did an excellent job with the earlier series of drillings under the dunes. This is unique, specialist work that demands extreme care. Despite various changes in the schedule, NRG did an excellent job thanks to their flexibility and commitment, and everything was completed on time with due regard for the local community.”

      About Hollandse Kust (west Beta)
      The offshore wind farm Hollandse Kust (west Beta) will have a capacity of 700 MegaWatt and will be put into operation in 2026. The Hollandse Kust (west Beta) offshore grid is the total grid connection from the Hollandse Kust (west Beta) offshore wind farm to the new transformer station at Wijk aan Zee. From there the power goes via underground cables to the high-voltage station along the A9 highway in Beverwijk. This high-voltage station is part of the national high-voltage grid (Noordring 380 kV).

      The total project consists of:

      • The offshore transformer platform: all wind turbines will be connected to this platform and the voltage level will be increased from 66 kiloVolt (kV) to 220 kV;
      • The offshore 66 kV interlink cable between the platform for west Alpha and the platform for west Beta;
      • Two 220 kV offshore cable systems to the transformer station. The cables will come ashore south of Wijk aan Zee;
      • Expansion of the transformer substation being built for the Hollandse Kust (north) and (west Alpha) wind farms. At the transformer station, the power will be brought from 220 kV AC to 380 kV AC. From there, the power will be fed into the national high-voltage grid via underground 380 kV cables some ten kilometers further along the A9 highway.

      Investing in green energy

      With annual planned investments expected to grow to at least EUR 6 billion by 2025, TenneT is heavily investing in the energy transition in Europe, making an important contribution to meet national climate targets and to connect everyone to a brighter energy future, whilst maintaining a solid financial position.

       

      The majority of TenneT's investments are directly related to the increase in renewable energy sources, such as wind and solar energy. Around 2030 TenneT expects to have realized at least 38 gigawatt (GW) of connection capacity for offshore wind farms in the Dutch and German parts of the North Sea.

      • TenneT and Siemens Energy confirm partnership at press briefing to mark next project milestone
      • TenneT COO Tim Meyerjürgens urges politicians to consistently accelerate grid expansion processes
      • 900 megawatt grid connection for the transmission of wind energy from sea to land

      TenneT COO Tim Meyerjürgens and Tim Holt, Member of the Managing Board of Siemens Energy, took a tour of the offshore platform of the DolWin6 grid connection project to see for themselves the successful progress of construction at the Dragados shipyard in Cádiz, Spain. The offshore platform DolWin kappa, which is part of the project, is largely prepared for sailing out towards the German North Sea and is thus about to reach the next milestone. The first tests in preparation for commissioning, which is scheduled to be completed after the platform installation in the German North Sea, are already underway. DolWin6 will be TenneT's 13th offshore grid connection system in the German North Sea for the transmission of wind energy from sea to land. It will be connected to the grid in 2023 and, with 900 megawatts, has the capacity of a large power plant. Siemens Energy has been commissioned by TenneT as general contractor to build the system.

      The strong and proven partnership between TenneT and the contractor Siemens Energy made a decisive contribution to the successful and timely progress of the project, Tim Meyerjürgens explained. Against the backdrop of the German government's ambitious offshore expansion targets of 30 gigawatts by 2030 and the heightened concerns about Germany's energy security due to the war in Ukraine, he emphasised the importance of the DolWin6 connection system.

      At the same time, Tim Meyerjürgens made it clear that the purely announcement of new German expansion targets for renewable energies by politicians and the acceleration measures for the expansion of renewable energies in the so-called "Easter Package" are not enough. "We welcome these ambitious targets, but the politicians must now follow up consistently and set the course in the 'summer package' so that the acceleration of grid expansion at sea can also succeed and, in parallel, also receive the decisive impetus on land. In concrete terms, this means: approval procedures must be accelerated, their level of detail reduced and offshore construction windows extended," Tim Meyerjürgens told journalists in Cádiz. "Together with the other transmission system operators, we have submitted concrete proposals to the politicians and the supervisory authority on how the increased construction targets would be technically feasible within the timeframe specified. However, interventions in planning processes or changes to legal requirements for projects that have already been put out to tender, are under construction or are about to be built are counterproductive and lead to the opposite effect, namely delays," Tim Meyerjürgens made clear.

      news-2631 Mon, 11 Apr 2022 11:41:04 +0200 TenneT in search of flexible power in Brabant and Limburg https://netztransparenz.tennet.eu/tinyurl-storage/detail/tennet-in-search-of-flexible-power-in-brabant-and-limburg/ The national grid operator TenneT is looking for parties in Limburg and Brabant who can flexibly handle their electricity supply and demand. This exploration is part of a so-called congestion study that the grid operator is currently conducting in order to use the busy electricity grid in these two provinces even more intensively. The national grid operator TenneT is looking for parties in Limburg and Brabant who can flexibly handle their electricity supply and demand. This exploration is part of a so-called congestion study that the grid operator is currently conducting in order to use the busy electricity grid in these two provinces even more intensively.

       

      In Brabant and Limburg, there is a rapidly growing demand for extra capacity on the electricity grid, particularly due to the arrival of many solar parks. The amount of electricity generated by these is greater than the electricity grid can currently handle. Plenty of investments are being made in both regions to strengthen and expand the grid, but these take a long time. TenneT therefore announced last year a temporary halt to new connections and at the same time began investigating possibilities for using the existing grid more intensively.


      Flexibility to create more space on the grid

      In this so-called congestion study, TenneT explores whether customers connected to the electricity grid can flexibly handle their supply or demand in exchange for a fee. This means that, in the event of an imminent overload, the grid operator will ask these parties to temporarily supply less to the grid or to purchase more. The use of flexibility at peak times creates more space on the grid to connect new parties.

      TenneT has drawn up a questionnaire for the Brabant and Limburg region, which potential suppliers can use to indicate to what extent they can supply flexibility. These can be either parties that are directly connected to the high-voltage grid or parties that are connected to the regional grid of Enexis. TenneT will study the input from potential suppliers in more detail and incorporate it into its congestion management study. The results of the study are expected before the summer.


      New regulations in the pipeline

      The study in Brabant and Limburg fits in with a new development that is currently being worked on within the energy sector. Regulator ACM will publish new rules in the course of 2022, in which this is further elaborated. The congestion study in Brabant and Limburg will be carried out in anticipation of these new rules and regulations.


      Two billion for investments in Brabant and Limburg

      The use of flexibility is one of the measures to accelerate the creation of more connection space to the grid. In Brabant and Limburg, the use of the “vluchtstrook” of the electricity grid to connect more sustainable projects is also being considered. In addition, Brabant and Limburg are working hard to reinforce the high-voltage grid. Additional connections and high-voltage substations are being built and the grid is being upgraded to facilitate all sustainable projects. TenneT will invest over two billion euros in this during the next ten years.   


      Similar studies in other regions

      TenneT expects that flexibility can make a significant contribution to the more intensive use of the electricity grid and thus to the accelerated provision of additional connection capacity. In the near future, consultations will also begin similar to these in Friesland, Flevoland, Utrecht and Gelderland, where grid capacity is also limited due to rapid developments resulting from the energy transition. A study has already been completed in Zeeland, where preparations are being made for the future use of flexibility in the event of scarce network capacity.

TenneT completed the installation and energization of the offshore grid connection. Wind farm developer Vattenfall can now connect the wind turbines to the high voltage grid. On top of that, the Hollandse Kust (zuid) Beta topside was successfully installed this week.

      Grid Readiness

      TenneT received the ‘Grid Readiness’ certification from DNV GL for Hollandse Kust (zuid) Alpha on Tuesday March 22nd. This means that this offshore grid connection fully complies with the conditions set out in the so-called Offshore Wind Energy Development Framework. Marco Kuijpers, Director of Large Projects Offshore: "With the energization of the Hollandse Kust (zuid) Alpha connection, 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 and has a capacity of 700 MW. The energization of Hollandse Kust (zuid) Beta later this year will add another 700 MW from wind farms Hollandse Kust (zuid) III and IV.”

      Made in Dubai

      Over the past years, contractor Petrofac has been working on the fabrication of two High Voltage Alternating Current (HVAC) transformer stations – also called topsides – Alpha and Beta at the Drydocks World fabrication yard in Dubai. The Alpha topside was installed on the jacket in the North Sea, about 20 kilometers off the coast of The Hague, on Sunday December 26th 2021. Sister topside Beta left the fabrication yard in Dubai last February and sailed on a Boskalis transport vessel in little over one month to the Alexiahaven on the Maasvlakte, where it arrived last week.

      Offshore company Allseas carried out the installation

      In the Alexiahaven, the Beta topside was loaded from the transport vessel onto the platform installation vessel Pioneering Spirit of offshore company Allseas, which then sailed to the installation location at sea. After completion of preparatory work, Pioneering Spirit accurately positioned the Beta topside on the jacket this week.

      Significant milestone in the delivery of this important energy transition project

      Sami Iskander, Petrofac Group Chief Executive: “The safe installation of the Beta topside is a significant milestone in the delivery of this important energy transition project. Everyone involved should be proud of this achievement.”

      Marco Kuijpers adds: “I am very pleased that the project was installed safely and I compliment Petrofac and Allseas with this. Wind energy plays a crucial role in the energy transition, also in industry, and I am proud that TenneT, together with our partners, can contribute to a sustainable future in this way."

      When the wind farm area Hollandse Kust (zuid), 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.

      Renewable energy from the North Sea to the high voltage grid on the Dutch mainland

      The green energy generated by the wind turbines in the North Sea is collected at an offshore transformer station. The voltage is converted from 66 kV into 220 kV. The electricity is then transported to land via cables in the seabed and is landed at an electrical substation at the Maasvlakte. At this substation the voltage is converted into 380 kV. Finally, the electricity is transported to the high voltage grid via high voltage station Randstad 380 kV Zuidring.

      Offshore green energy by the end of 2023

      By the end of 2023 TenneT will have constructed 3,500 MW offshore grid connections for offshore wind farms in the Dutch North Sea. The first 1,400 MW has been realised with the delivery of Borssele Alpha and Beta in 2019 and 2020. It will now be the turn of Hollandse Kust (zuid) Alpha and Beta this year, followed by Hollandse Kust (noord) in 2023. TenneT is using five identical 700 MW transformer platforms for these wind farms. These platforms are located close to the wind farms and all five use the same type of 220 kV cable connection to the coast. Such standardisation enables TenneT to complete these projects more efficiently, more quickly and more economically.

      Towards 2030, the Dutch and German governments will set new targets for offshore wind. The Dutch government recently announced new areas and targets with a total installed capacity of 20,7 GW around 2030. In Germany, on top of the already increased ambitions new offshore wind targets will be announced soon.

TenneT has had investigations carried out on the jacket (substructure) that was damaged in January during storm Corrie by a collision with the adrift vessel Julietta D.  The installation of the second offshore transformer platform for the grid connection of wind farm Hollandse Kust (zuid) can be carried out as planned. TenneT has had investigations carried out on the jacket (substructure) that was damaged in January during storm Corrie by a collision with the adrift vessel Julietta D. 

      The investigation shows that the damage to the jacket is limited. The damaged parts of the jacket can be repaired at a later stage after topside installation. TenneT expects the Hollandse Kust (zuid) Beta topside to be installed at the end of March or early April.

      Collision during storm

      On Monday 31 January, the freighter Julietta D. was adrift due to storm Corrie in the area where TenneT is building two transformer platforms (Hollandse Kust (zuid) Alpha and Beta). These transformer platforms are part of the offshore connection of wind farm Hollandse Kust (zuid). The wind farm is being built by Vattenfall. The cargo ship collided with the Beta jacket. No people were working at the platform at that moment.

      Stormy weather in February

      The persistent stormy weather in February meant that inspections of the damage could not be carried out immediately. In addition to the inspection of visible damage above water, underwater investigations were also carried out to determine any damage to the substructure. This underwater investigation took more time due to relatively high waves and poor visibility. The investigation now shows that the damage is limited to paint damage and a few dents on one of the legs of the platform and damage to one of the four landing platforms for working vessels.

      Safe installation

      Joris Engelen, TenneT's Platform Project Lead: "When designing and building our jackets, scenarios are taken into account that a ship of limited size may collide with the jacket. After the initial fright of the collision, we set up and implemented an extensive investigation plan in cooperation with the parties involved. The jacket is expected to be in operation for many years. We are therefore relieved that the inspections and the investigations show that we can install the top side of the transformer platform on the jacket safely and as scheduled. After the top side has been installed, the repairs of the damages on the jacket can be carried out." The top side is currently being shipped to its destination in the North Sea. TenneT expects that the top side can be installed at the end of March or beginning of April.

      • Investment of EUR 4 billion in European energy transition and system resilience in 2021
      • Solid financial performance with an underlying revenue of EUR 6.4 billion; EUR 4.25 billion of equity capital committed by Dutch government
      • Looking ahead, growth must be responsible and smart, taking account of finite resources
      • Annual investment growing to a minimum of EUR 6 billion by 2025 

      TenneT invested a record EUR 4 billion in the expansion and maintenance of its grids last year, rising to the challenge of the energy transition. The unjustifiable attack on the Ukraine teaches us that European cooperation and alignment is now more important than ever. This conflict will undoubtedly be an important additional driver to accelerate a sustainable energy system. Meeting current climate objectives requires fundamental changes to the planning, operation and configuration of the whole electricity system. TenneT is also intensifying the smart use of its grids. Looking ahead, the steep increase in the production of renewable electricity and the electrification of our society means TenneT will increase its output towards a minimum annual investment level of EUR 6 billion by 2025. Because a secure and reliable high-voltage grid is one of the decisive factors in driving the energy transition, TenneT is developing and building a grid that’s ready for a fossil-free energy system by 2045: the Target Grid. TenneT managed to maintain a very high grid availability of 99.99999% overall. At the same time, TenneT is fully aware of the congestion issues on the Dutch grid and the restrictions on new customers currently seeking connection to the electricity grid. Together with its stakeholders, TenneT is working hard to address this.

      TenneT is already delivering critical projects to drive the energy transition in Europe. For example, commercial operations of the NordLink cable began in 2021, connecting Germany and Norway through a 623-kilometre subsea cable. When electricity prices in Germany are high, due to limited wind or sun, consumers benefit from lower-priced hydroelectric power from Norway. This ‘green link’ can supply more than 3.6 million German households with renewable electricity.

      Manon van Beek, CEO of TenneT: “Even as we work at speed to build and maintain our grid for a fossil-free future, demand for grid capacity in the here and now is also growing fast. Linear growth alone cannot solve this squeeze, and we are looking at many ways to make smarter use of our existing grid as well as investing much time and effort into so-called system thinking. The latter involves holistic solutions and systemic planning for the entire energy system and is a real leap forward for the energy transition. To this end, we are focusing on faster project delivery, proactive planning, and innovative solutions. In this context, I would like to thank the many experts and partners who dedicated themselves to developing the Target Grid and the Wind Power Booster.”


      Green and sustainable financing

      TenneT’s large-scale investment programme requires broad, sustainable and timely access to financing with a good balance between equity and debt to maintain our solid credit ratings. To that end, the company is very pleased that the Dutch government announced EUR 4.25 billion of equity capital for the activities in the Netherlands. For TenneT’s equity capital requirements in Germany the options are still being explored. TenneT is confident that a solution will be reached in 2022 in coordination with its shareholder, the Ministry of Finance. The (social) benefits of TenneT as an integrated cross-border company are central to finding a solution.

      Arina Freitag, CFO of TenneT: "This decade will require record investments in the energy transition in Germany, the Netherlands and Europe. It is the only way to achieve the ambitious goals and timetables on the path to climate neutrality. To get this done, it is of critical importance that the regulatory framework clearly favours innovation and digitalization in the energy industry. TenneT, as a transmission system operator that connects the large energy potential of the North Sea to industrial centres is committed to play a pivotal role in achieving our governments' climate ambitions.”

      Last June, TenneT issued its largest (EUR 1.8 billion) and first-ever green triple tranche Euro bond transaction, reinforcing TenneT’s top-three status as a corporate issuer of sustainable, green debt financing in Europe, with currently over EUR 13 billion of green debt issued across different debt formats. During 2021, access to the debt financing markets remained exceptionally good.

      Frameworks for green growth

      In the coming years, the focus will remain on speeding up the implementation of the project portfolio and working on smart solutions to address congestion issues. Harnessing flexibility for the grid is crucial and TenneT is working on options such as demand-side response, hydrogen conversion for storage and decentralised flexibility provided by household appliances and electric vehicles. Recruiting technical talent is also a priority. TenneT aims to continue growing its workforce and sees targeted investments in technology education necessary to address the ongoing scarcity in this area. By working closely with secondary and higher vocational educational institutions TenneT attracts and educates young people for the energy infrastructure sector.

      To deliver what is needed, TenneT requires streamlined and modern planning and approval procedures, as well as political support for our grid reinforcements and expansion at all levels. In addition, regulations and legislation suited to transforming the energy system must be in place: forward-looking regulation fostering innovation is instrumental to speeding up progress. Market parties are waiting for frameworks that encourage them to invest heavily in renewables, flexible electricity supply and demand as well as other grid innovations. Collaboration and collective responsibility will determine the success of the energy transition.

    • New offshore standard set by the 2GW Program will accelerate Europe’s energy transition
    • With a combined six gigawatts, BalWin1, BalWin2 and BalWin3 will meet 20 per cent of the expansion targets for offshore wind by 2030 set out in the coalition agreement of Germany's new federal government
    • The three projects in the German North Sea will supply around 7.5 million households with green offshore electricity
    • TenneT will be constructing three offshore grid connections (BalWin1, BalWin2 and BalWin3) in the North Sea off Lower Saxony, each with a transmission capacity of two gigawatts. The company is now launching the tendering procedures for the sea and land stations for these grid connection systems. The contracts for all three projects have a combined order volume in the seven-digit range and are expected to be awarded in the third quarter of 2023. Effective immediately, bidders can qualify for the tender process.


      The first three German two gigawatt projects will be part of TenneT’s innovative, transnational 2GW Program. Featuring two gigawatts per system, the new offshore standard will offer more than twice the transmission capacity of the 900 megawatt systems that have been common in Germany to date. Since this will allow the same amount of electricity to be transmitted with only half as many grid connections, it will be possible to conserve important resources and minimise environmental impacts. Harmonising the systems in terms of technology and planning will also make it possible to put additional grid connections systems in place even faster than before. In this way, the 2GW Program will make wind energy from the North Sea scalable and the supply of green electricity more cost-efficient.


      “The 2GW Program will be a key pillar of our offshore strategy while helping to advance the energy transition in Europe more quickly and efficiently,” says Tim Meyerjürgens, Chief Operating Officer of TenneT. “After a successful launch in the Netherlands and with the call for tenders for the converter stations of our BalWin projects, we are now also putting grid expansion in the German North Sea on course for climate neutrality.” The call for tenders encompasses the newly developed offshore platforms, the land stations, and the associated equipment for the new two gigawatt high-voltage direct current (HVDC) transmission technology.


      As part of the 2GW Program, at least six offshore grid connection systems – each with a transmission capacity of two gigawatts wind energy from the North Sea – are to be built in Germany and the Netherlands by 2030, with three of them being in the German BalWin cluster off the coast of Lower Saxony. With a total capacity of six gigawatts, BalWin1 (completion 2029), BalWin2 (2030) and BalWin3 (2030) will contribute 20 per cent to the raised offshore expansion target of Germany’s new federal government by 2030. Together, BalWin1+2+3 will reliably and safely bring green electricity from sea to land for approximately 7.5 million households. TenneT is planning at least three more projects off the coast of the Netherlands with a combined total of six gigawatts. With this magnitude, the projects in TenneT’s 2GW Program have the potential to become a European beacon for offshore grid expansion and secure supply – today and tomorrow.

      About the 2GW Program

      TenneT’s 2GW Program plays a vital role in tackling the energy transition from offshore and will help Europe become the world’s first climate-neutral continent. This new standard combines our extensive know-how in offshore grid development with a unique transnational approach. Through its strong focus on harmonisation and standardisation, the programme delivers a blueprint for future offshore grid connection systems and allows for a more rapid scale-up. Meanwhile, a larger capacity of two gigawatt per system reduces the number of grid connections needed. The 2GW Program will provide Europe and its inhabitants with more green energy in a safe and cost-efficient way – all with the least environmental impact possible. The six standardised offshore grid connections planned in the Dutch and German North Sea by 2030 will strengthen TenneT’s role as a reliable partner in the North Sea for the European energy transition.
      The 2GW Program sets a new beat for the European energy transition.

    • New consortium prevails: McDermott and GEIRI/C-EPRI win bid for converter stations at sea and on land
    • 980 megawatt grid connection - output of a large power plant
    • Record length of 190 kilometres of subsea cable
    • In the tendering process for the construction of the 235-kilometre-long offshore grid connection system BorWin6, TenneT has awarded the contract for the converter stations at sea and on land to the McDermott and GEIRI/C-EPRI consortium. The "stations" lot has thus been awarded, the second "cable" lot for the cable between the two stations will follow in summer 2022.

      "With regard to the high expansion targets for offshore wind energy in the North Sea, we are pleased that an international consortium was able to prevail in our tendering procedure. Even though this consortium is new to us, it has a lot of experience in the offshore as well as the high-voltage direct current transmission (HVDC) business," said Tim Meyerjürgens, COO of TenneT. "As a transmission system operator, we will need many reliable partners in the coming years to enable the offshore expansion at the desired pace and with the targeted connection capacities. In terms of speeding up the process, we have taken the lead with this project: It was initially planned with a connection capacity of 930 megawatts. In the technical planning, we were able to increase the capacity by 50 megawatts. The project was recently confirmed in the latest grid development plan."

      The direct connection principle is also used for BorWin6, which means that TenneT connects the wind turbines directly to TenneT's offshore platform BorWin kappa via 66-kilovolt three-phase cables. This eliminates the need of transformer stations that were previously necessary in each and every wind farm. In addition, 155-kilovolt three-phase cables are not required to connect TenneT's offshore platform with that of the wind farm. Economically speaking, this in-novative technology leads to enormous cost savings.

      Tim Meyerjürgens: "With the award of BorWin6, we are continuing the ongoing cost reduction in the construction of offshore grid connection systems. We are also applying the smart platform concept by installing particularly low-maintenance technology on the offshore platform. This enables us to reduce the maintenance effort and ultimately the operating costs of the asset.”

       

      On a 235-kilometre-long route, TenneT transmits the electricity via underground cable by using low-loss direct current technology (DC) from the offshore converter station BorWin kappa to the converter station in Büttel (Schleswig-Holstein) on land. Here, the direct current is converted back into three-phase alternating current (AC) and fed into the extra-high voltage grid.

      Within the consortium, the focus of McDermott will be on the converter stations; they draw on a wide range of offshore experience and their own worldwide fabrication yards. Global Energy Interconnection Research Institute Co. Ltd. (GEIRI) & C-EPRI Electric Power Engineering Co. Ltd. (C-EPRI), in turn, will focus on electrical engineering. Many high-voltage DC projects have already been realised, primarily in Asia, and GEIRI/C-EPRI is regarded as an experienced HVDC developer and supplier worldwide.

      BorWin6 is the last offshore grid connection system to be implemented by TenneT in the German North Sea with 320-kilovolt technology. The technological leap to 525-kilovolt and a transmission capacity of two gigawatts will be implemented in future projects. BorWin6 is scheduled to go into operation in 2027.


      The milestones at a glance

      The contract for the second lot, for the production and laying of the cables, will be awarded before the end of this year. In addition, the first preparatory measures for the construction of the land station in Büttel are planned. The actual construction of the land station will begin in 2024. Construction of the topside, i.e. the actual converter station at sea, which will be built in Qing-dao (China), is expected to start in mid-2023. Construction of the jacket in Batam (Indonesia) will also start at the end of 2023. The jacket will form the substructure on which the platform will be placed in the approximately 38-metre-deep water, probably in mid-2026.

      In 2023, horizontal drillings are also planned to underpass the land protection dike (near Büsum) and the Kiel Canal; the land cable will be laid in 2024 and 2025, and the subsea cable in 2025 and 2026.

       

      Facts and figures on BorWin6

      Next to the projects BorWin1+2+3 and 5, BorWin6 is the fifth offshore grid connection to be realised by TenneT off the coast of Borkum using extra-high voltage direct current transmis-sion technology. BorWin6 has a transmission capacity of 980 megawatts, and commissioning is planned for 2027.

      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://netztransparenz.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).

The onshore electricity quantities for the months October to December 2021 partly include preliminary estimated values.

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). This will also create greater risks for the security of supply for the Netherlands.

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. 

       

      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. 

      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.

    • 2 GW standard essential to meet increased Dutch and German 2030 offshore targets
    • 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.
