Four cables will have to be buried into the North Sea seabed for this purpose. For the first ten kilometres of the cable route at sea, these cables will have to be buried more than 5,5 meters into the seabed in order to cross the busy shipping route  Rotterdam Maasmond. The installation of the cables started on September 22nd  by pulling the cable ashore. The Deep Dig-It trencher crossed the Rotterdam Maasmond successfully and is on its way to the recently installed offshore Alpha jacket in the Hollandse Kust (zuid) wind farm area.  To the north of the Maasvlakte, TenneT is building the Hollandse Kust (zuid) offshore grid  to connect new offshore wind farms. Four cables will have to be buried into the North Sea seabed for this purpose. For the first ten kilometres of the cable route at sea, these cables will have to be buried more than 5,5 meters into the seabed in order to cross the busy shipping route  Rotterdam Maasmond. The installation of the cables started on September 22nd  by pulling the cable ashore. The Deep Dig-It trencher crossed the Rotterdam Maasmond successfully and is on its way to the recently installed offshore Alpha jacket in the Hollandse Kust (zuid) wind farm area. 

The Van Oord/Hellenic Cable Consortium will be installing 4 subsea 220 kV AC cables that will connect 2 offshore platforms to the onshore electricity grid. The first 2 cables to the Alpha platform will be installed this year. The other 2 cables, meant for the Beta platform, will follow in 2021. The last few days the preparatory work has been completed. The cable was pulled ashore via a direct drill to the new transformer substation that is being built on the Maasvlakte. From this point, the cable with a total length of 42 kilometres to the wind zone Hollandse Kust (zuid) will be laid by the contractor combination Van Oord - Hellenic Cables. For this purpose, Van Oord has specially developed the Deep Dig-It, a large remote-controlled trencher.

Deep Dig-It
Van Oord's Deep Dig-It is a so-called "Tracked Remotely Operated Vehicle" (TROV) that drives unmanned over the seabed and creates a deep trench for the cables by liquefying the seabed. At the same time, the trencher inserts the cables into the trench and seals them again into the seabed. This new trencher is one of the largest and most powerful of its kind. The trencher weighs 125,000 kilos, is over 17 meters long, more than 8 meters high, and 11 meters wide. The Deep Dig-It is very powerful, comparable to no less than two Leopard tanks (2,500 hp) and can bury cables more than 5,5 meters deep in very hard soil. The Deep Dig-It is controlled at Van Oord's offshore installation vessel MPI Adventure, which is also equipped with a crane to launch and take out the Deep Dig-It.

Project net op zee Hollandse Kust (zuid)
The Hollandse Kust (zuid) offshore wind farm is located 22 kilometres off the coast of the Dutch province of Zuid-Holland. The sea cables connect the two offshore platforms with the Maasvlakte high-voltage substation and the Randstad 380 kV South ring. The wind energy is then fed into the national high-voltage grid to the electricity consumers in the Netherlands.

In 2018, TenneT commissioned the Van Oord-Hellenic Cables consortium to build the offshore connection for the net op zee Hollandse Kust (zuid) project. The consortium will install and bury the sea cables that cross the entrance to Europe's busiest freight port, the port of Rotterdam. The 1,400 MW grid connection will be completed in 2022 and will eventually provide electricity for 1.6 million households. The offshore wind farm contributes significantly to the Dutch government's objective of having a total of 3.5 GW installed offshore wind energy capacity by 2023. With the commissioning of Borssele Alpha and Beta this year, the first 1.4 GW has been realized.

Offshore wind until 2030
After Hollandse Kust (zuid) Alpha and Beta the next project of the offshore grid will be the connection of Hollande Kust (noord). TenneT uses the same type of 700 MW transformer platform five times for the grid connection. The platforms are located close to the offshore wind farms. The offshore cable is also five times the same type of 220kV cable connection. This standardization enables TenneT to build these projects more efficiently, faster and cost effectively. TenneT will realize another 6.1 GW of high-voltage connections for wind farms in the Dutch North Sea until 2030. In the German North Sea TenneT has already realized 7.1 GW and the capacity of TenneT's offshore grid connections in Germany will be increased to approximately 17 GW in 2030.

news-2178 Tue, 22 Sep 2020 16:26:00 +0200 National Grid and TenneT to jointly develop vision to link offshore wind farms to Britain and the Netherlands https://www.tennet.eu/news/detail/national-grid-and-tennet-to-jointly-develop-vision-to-link-offshore-wind-farms-to-britain-and-the-ne/ National Grid Ventures, the commercial development arm of National Grid plc, and Dutch Transmission System Operator TenneT have today (22 Sept), announced a cooperation agreement to explore the feasibility of connecting Dutch and British wind farms to the energy systems of both countries via subsea electricity cables called interconnectors. The development would be the first of its kind for the UK and the Netherlands in the North Sea. National Grid Ventures, the commercial development arm of National Grid plc, and Dutch Transmission System Operator TenneT have today (22 Sept), announced a cooperation agreement to explore the feasibility of connecting Dutch and British wind farms to the energy systems of both countries via subsea electricity cables called interconnectors. The development would be the first of its kind for the UK and the Netherlands in the North Sea.

Harnessing the full potential of offshore wind will play a vital role in decarbonising European economies and societies by 2050. The UK and the Netherlands have both established ambitious targets to expand offshore wind capacity in the North Sea, with the UK government recently announcing it was targeting 40 gigawatts by 2030, whilst the Dutch have targeted 11.5 gigawatts by 2030 and another increase of 20-40GW by 2050. Delivering such large-scale offshore wind growth efficiently will require significant amounts of new infrastructure and close cooperation between countries around the North Sea.

The announcement follows a recent decision by the Dutch government to future-proof the first far shore high voltage direct current (HVDC) 2GW offshore transmission grids in the Netherlands for the IJmuiden Ver Wind Farm Zone, approximately 80km off the North-West coast. 

Under the terms of the cooperation agreement, TenneT and National Grid Ventures will explore the development of a multi-purpose interconnector (MPI) to simultaneously connect up to 4 gigawatts of British and Dutch offshore wind between the British and Dutch electricity systems, providing an additional two gigawatts of interconnection capacity between the countries.

By connecting into both systems, the MPI will enable spare transmission capacity to be used to trade electricity between the countries, thereby increasing the potential utilisation of offshore infrastructure. Reducing the amount of infrastructure needed will also mitigate the environmental impact on coastal communities, compared to the current approach in which interconnectors and wind farms are developed and connected separately.

The two companies aim to have a “path-finder” project defined by the end of 2021 with a view to delivering an operational asset by 2029.

Manon van Beek, CEO of TenneT, said: “TenneT has been at the forefront of developing multi-purpose interconnection to enable the large-scale growth of offshore wind in the North Sea. This agreement allows us to work with National Grid in the North Sea to develop innovative infrastructure that uses every spare electron of offshore wind generation to reach our decarbonisation targets.”

Jon Butterworth, Managing Director of National Grid Ventures, said: “The UK’s binding commitment to net zero by 2050 and the European Green Deal have set clear goals for a low-carbon future for generations to come. Multi-Purpose Interconnectors have the potential to act as a key enabler for new offshore wind projects and we’re delighted to be partnering once again with TenneT to deliver an innovative vision to help realise the full green energy potential of the North Sea.

news-2171 Mon, 07 Sep 2020 14:48:18 +0200 First jacket offshore substation Hollandse Kust (zuid) installed in seabed https://www.tennet.eu/news/detail/first-jacket-offshore-substation-hollandse-kust-zuid-installed-in-seabed/ The first jacket of TenneT's Hollandse Kust (zuid) offshore platform has been installed successfully in the seabed. The heavyweight Alpha jacket of 3200 tons was transported by the heavy lifting crane vessel - the Sleipnir – in the wind farm area on Saturday 5 September. The jacket will be further installed in the next days The first jacket of TenneT's Hollandse Kust (zuid) offshore platform has been installed successfully in the seabed. The heavyweight Alpha jacket of 3200 tons was transported by the heavy lifting crane vessel - the Sleipnir – in the wind farm area on Saturday 5 September. The jacket will be further installed in the next days

The jacket is 29 meters long, 20 meters wide and 46 meters high. It is the foundation for the first of two transformer substations for the wind farm Hollandse Kust (zuid). The two 220 kV sea cables that bring the power from the wind farms ashore will be connected to the Alpha jacket in the next months. In 2021, the top side of the substation, will be installed onto the jacket. At the end of 2021, the offshore platform is expected to be in operation. Vattenfall will use the Alpha and Beta platforms to connect the Hollandse Kust (zuid) wind farms to the grid.

Offshore schematic presentation offshore grid wind energy to 2023

By the end of 2023 TenneT will have constructed 3,500 MW offshore grid connections for offshore wind farms. The first 1,400 MW has been realised with the delivery of Borssele Alpha and Beta. It will then be the turn of Hollandse Kust (zuid) Alpha and Beta, followed by Hollandse Kust (noord). 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 connections to the coast. TenneT COO Tim Meyerjürgens: "Such standardisation enables TenneT to complete these projects more efficiently, more quickly and more economically."


Offshore Grid Programme 2024-2030

According to the Follow-up Roadmap for Offshore Wind Energy, a further 6.1 GW (6,100 MW) of offshore wind farms will be built from 2024 through to the end of 2030. These wind farms will be located in the wind energy areas known as Hollandse Kust (west), Ten Noorden van de Waddeneilanden and IJmuiden Ver. For the first two, TenneT will again be using three standardised 700 MW platforms (2.1 GW). The efficient connection of wind energy areas further out into the North Sea, such as IJmuiden Far (4 GW), will partly require other technologies that use direct current instead of alternating current. IJmuiden Ver will have two offshore converter stations, each with a capacity of 2 GW, which is unique in the offshore wind industry.


Offshore grid connections Germany

In the German part of the North Sea, TenneT's 7.1 GW current connection capacities already exceeds the German government's target for 2020. This target has been set at around 6.5 gigawatts for the North Sea and the Baltic Sea together. Until 2030, TenneT' s offshore grid connection capacity in Germany will be increased to around 17 GW.

news-2160 Tue, 11 Aug 2020 08:42:39 +0200 Offshore grid connection BorWin5: TenneT awards contracts for converter stations and cables https://www.tennet.eu/news/detail/offshore-grid-connection-borwin5-tennet-awards-contracts-for-converter-stations-and-cables/ The consortium of Siemens AG and Dragados Offshore S.A. has been awarded the contract for the construction of converter stations on land and at sea, while NKT HV Cables AB has been awarded the contract for the production and installation of the DC underground and submarine cables.With 230 kilometres the longest offshore direct current connection to dateCommissioning of the 900 megawatt connection is scheduled for 2025
  • The consortium of Siemens AG and Dragados Offshore S.A. has been awarded the contract for the construction of converter stations on land and at sea, while NKT HV Cables AB has been awarded the contract for the production and installation of the DC underground and submarine cables.
  • With 230 kilometres the longest offshore direct current connection to date
  • Commissioning of the 900 megawatt connection is scheduled for 2025
  • In the tendering procedure for the contract to build the longest offshore grid connection sys-tem, BorWin5, with 230 kilometres, TenneT has awarded the contracts for the converter sta-tions on land and at sea to the consortium Siemens AG / Dragados Offshore S.A. The con-tracts for the DC underground and submarine cables have been awarded to NKT HV Cables AB.

    “With regard to our latest offshore project, we are delighted to not only award the contract to Siemens and Dragados, two companies that are both proven and innovative in the construc-tion of converters but also to NKT, another powerful supplier in the market for plastic-insulated direct current cables ", said Tim Meyerjürgens, COO of TenneT.

    BorWin5 is the 15th offshore grid connection system to be realised by TenneT in the German North Sea and also the twelfth direct current connection.

    Tim Meyerjürgens: "With the award of BorWin5, we are proceeding with the continuous cost reduction in the construction of offshore grid connection systems. Compared to the predecessor project DolWin5, we were again able to achieve a significant cost reduction for the converter stations. One reason is that for BorWin5 the smart platform concept is being used for the first time. This not only keeps the costs for the platform construction manageable, but also allows us to extend the intervals for maintenance and servicing to once a year". With the smart platform concept, TenneT is continuing to drive forward standardisation. In accordance with the principle 'as little as possible, as much as necessary', we only install the technology on the offshore platforms that has to be available offshore. In doing so, we make use of the extensive experience gained from the grid connection systems already in operation.

    In addition, BorWin5 is the second project after DolWin5, in which the wind turbines are directly connected to the offshore platform BorWin epsilon via 66-kilovolt three-phase power cables. This eliminates the transformer stations that were previously required in every wind farm. In addition, 155-kV three-phase current cables are no longer required to connect the TenneT offshore platform with the wind farm. By means of a 230-kilometre-long extra-high-voltage direct current cable, TenneT transmits the electricity to the Garrel/East converter station on land after conversion using low-loss direct current technology. Here, the direct current is converted back into three-phase alternating current and fed into the extra-high voltage grid. With the 66 kV direct connection, BorWin5 belongs to the new generation of cost-efficient offshore grid connections, which make an important contribution to the energy transition. 

    About BorWin5

    BorWin5 is the fourth offshore grid connection – in addition to the projects BorWin1, 2 and 3 –TenneT is implementing off the coast of Borkum using high-voltage direct current transmission technology. BorWin5 has a transmission capacity of 900 megawatts and will connect the wind farm EnBW He Dreiht with the transmission grid. The commissioning of BorWin5 is planned for 2025.

    With the innovative 66-kV connection, the wind farms will be directly connected to the TenneT offshore platform. This means that transformer stations in the offshore wind farms are no longer necessary

    BorWin5: facts and figures

    • 230-kilometre-long connection using high-voltage direct current (HVDC) transmission tech-nology with a maximum transmission capacity of 900 megawatts 
    • 110 kilometres of land cable, 120 kilometres of submarine cable 
    • Grid connection point: Garrel/East (near Cloppenburg)
    • Planned commissioning in 2025

  • Talks with the German government about a potential equity participation next to the Dutch State are on-going.
  • Despite the corona pandemic and due to extensive measures taken to ensure a safe and healthy work environment, TenneT made good progress in managing the complexity of connecting growing amounts of renewable electricity to the grid. At the same time, TenneT maintained a high security of supply of 99.99 percent for 42 million end users across the Netherlands and Germany.

    Further integration pays off

    TenneT, as Europe's first cross-border TSO, continued to facilitate the development of a borderless European electricity market. TenneT increasingly benefits from its integrated grid planning, management and operations approach. Manon van Beek, CEO: "Sharing best practices and lessons learned between our German and Dutch operations is paying off more and more in terms of an integrated approach to offshore and onshore grid expansion, better grid utilization due to European innovations and cross-border energy system planning."

    Offshore, TenneT is on track to move the energy transition in the Netherlands forward making use of  its extensive experience in Germany. Borssele Alpha recently saw its first power delivered by the neighbouring wind farm. Borssele Beta has become operational end of July, well before the formal delivery date of 31 August 2020. Therefore TenneT has now got fourteen offshore grid connections in operation, twelve in the German and two in the Dutch North Sea. The 12th offshore grid connection in Germany, Borwin 3, was completed in the first half of 2020. This brings the total connection capacity in the German part of the North Sea to over 7 GW, exceeding the German government's sustainability target of 6.5 GW by the end of 2020.

    In order to reduce the impact of AC lines and to increase the public acceptance of those projects, Germany recently decided to start a couple of 380kV AC underground cabling pilots. TenneT benefits from the experience it gained in the Dutch Randstad with the construction of 380 KV underground AC lines. Furthermore this experience is also transferred to the large DC corridor projects like SuedLink and SuedOstLink. These huge -TenneT’ s largest-  projects, which will be built completely underground, will be crucial to transport northern wind production to meet demand for electricity in southern Germany.

    Scaling up and unlocking flexibility through innovation

    “We’ve proven to be resilient to the challenges posed by the corona pandemic,” says Van Beek. “Our construction work on onshore and offshore electricity connections is progressing. As well as maintenance. Our investment agenda increased by 30% in the first half year."

    On top of all grid expansion and maintenance efforts, TenneT is also investing heavily in innovations to better utilize and optimize the capacity and flexibility present in the existing electricity grids. In April, TenneT together with Terna (IT) and Swissgrid (CH) launched Equigy, a new European crowd balancing platform, supported by blockchain technology. This platform will enable millions of European prosumers to actively offer flexible capacity of their electric cars, domestic batteries or solar panels to grid operators for the stabilisation of the electricity system and thus financially benefit from the energy transition.

    Van Beek continues: "On 1 July, we launched a new organisational structure with a new senior leadership team that will support the company’s growth and its role in the energy transition in the Netherlands, Germany and neighbouring countries. New departments will further focus on strategic partnerships, digitalization and energy system planning. The new organisation marks an important milestone in TenneT' s transformation, which also includes a sharpened strategy and more focus on leadership and culture.

    TenneT expects to scale up to an annual invest volume of EUR 4 to 5 billion within the next few years. CFO Otto Jager explains: "We are going to connect growing amounts of renewable electricity to the grid while facilitating the development of a borderless European electricity market. In light of future equity funding needs, the ongoing talks with the German government about a possible equity participation, next to the Dutch State, are welcomed by TenneT."

    Financial results and outlook

    TenneT’ s financial performance in the first half year of 2020 remained solid. Underlying revenue of EUR 2,319 million increased by 7.1% compared to 2019 (EUR 2,166 million), mainly driven by a growing asset base and additional compensation for grid-related expenses. Underlying EBIT increased by EUR 7 million to EUR 414 million in the first half of 2020 (first half 2019: EUR 407 million).

    news-2154 Thu, 30 Jul 2020 09:00:00 +0200 Offshore grid connection Borssele Beta ready to land offshore wind power https://www.tennet.eu/news/detail/offshore-grid-connection-borssele-beta-ready-to-land-offshore-wind-power/ Borssele Beta, TenneT’s high voltage connection for offshore wind farms Borssele III, IV and V is ready for use. Blauwwind (Borssele III & IV) and Two Towers (Borssele V) can connect the wind turbines to the high voltage grid one month earlier than planned. TenneT has realised the entire Borssele project within schedule and budget.  Borssele Beta, TenneT’s high voltage connection for offshore wind farms Borssele III, IV and V is ready for use. Blauwwind (Borssele III & IV) and Two Towers (Borssele V) can connect the wind turbines to the high voltage grid one month earlier than planned. TenneT has realised the entire Borssele project within schedule and budget. 

    TenneT received the ‘Grid Readiness’ certification from DNV GL for Borssele Beta. This means that this offshore grid connection complies fully with the conditions set out in the so-called Offshore Wind Energy Development Framework. Marco Kuijpers, TenneT' s Director offshore activities: “We are proud of the fact that the second part of the Borssele high voltage connection is already complete and was realised within budget. Despite all the Covid-19 challenges, we were successful in continuing with the works; a huge achievement from all the contract parties involved.”  

    Important step in energy transition
    The Borssele III, IV and V wind farms will have a total capacity of 700 megawatts (MW), which is equivalent to the electricity consumption of around 1 million households. The electricity generated by the wind turbines is collected at sea at a transformer platform (“wall socket”). 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 Borssele. At this station it is converted into 380 kV. Finally, the electricity is transported to the high voltage grid. TenneT is investing in upgrading the 150 kV grid in Zeeland and the 380 kV connection between the Borssele and Rilland high voltage substations to secure the transport of higher volumes of sustainable energy in the future.

    Offshore schematic presentation offshore gridwind energy to 2023

    By the end of 2023 TenneT will have constructed 3,500 MW offshore grid connections for offshore wind farms. The first 1,400 MW has been realised with the delivery of Borssele Alpha and Beta. It will then be the turn of Hollandse Kust (zuid) Alpha and Beta, followed by Hollandse Kust (noord). 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.

    Offshore Grid Programme 2024-2030
    According to the Follow-up Roadmap for Offshore Wind Energy, a further 6.1 GW (6,100 MW) of offshore wind farms will be built from 2024 through to the end of 2030. These wind farms will be located in the wind energy areas known as Hollandse Kust (west), Ten Noorden van de Waddeneilanden and IJmuiden Ver. For the first two, TenneT will again be using three standardised 700 MW platforms (2.1 GW). The efficient connection of wind energy areas further out into the North Sea, such as IJmuiden Far (4 GW), will partly require other technologies that use direct current instead of alternating current. IJmuiden Ver will have two offshore converter stations, each with a capacity of 2 GW, which is unique in the offshore wind industry.

    Offshore grid connections Germany
    In the German part of the North Sea, TenneT's 7.1 GW current connection capacity already exceeds the German government's target for 2020. This target has been set at around 6.5 gigawatts for the North Sea and the Baltic Sea together. Until 2030, TenneT' s offshore grid connection capacity in Germany will be increased to around 17 GW.

    Hereby TenneT wants to inform the market on the upcoming changes in the process on contracting of Incident Reserve and Regulating Power.

    Week- and Daycontracts Incident Reserve and Regulating Power

    On January 2nd , 2020 the Dutch regulator (Autoriteit Consument & Markt) has informed the market regarding the decision (link)  to approve TenneT's request to postpone the startdate of daily tenders for Incident Reserve (mFRRda) and Regulating Power (aFRR). The regulator has approved TenneT's proposal for postponement of daily tenders  until September 1st 2020.

    In the "Staatscourant" number 28764 d.d. May 28th, 2020 (publication date May 29th, 2020, link) a revision of the Netcode has been published, which includes changes on the maximum  contract period for aFRR and mFRRda. From June 1st, 2020 the maximum contract period is one week, and from September 1st, 2020 the maximum contract period is one day.

    Weekly contracts for aFRR and mFRRda will be closed every Wednesday, in the week before the delivery week.

    From September 1st , daily contacts will be closed on the day before the delivery day, including weekends and holidays. Balancing Service Providers (BSPs) can send their offers using either the APFAS webportal or the B2B connection with TenneT.

    Offers Symmetrical aFRR

    As of January 1st, 2021 the exemption for the procurement of asymmetrical FRR expires, for that reason it will no longer be possible to combine upward and downward offers into a symmetrical offer. Therefore from delivery day January 1st 2021, all offers for aFRR and mFRRda need to be offered separately for upward- and downward regulation.

    news-2150 Mon, 27 Jul 2020 11:56:18 +0200 TenneT records a more than 21 % increase in offshore wind energy transmission and sets new standard for the future https://www.tennet.eu/news/detail/tennet-records-a-more-than-21-increase-in-offshore-wind-energy-transmission-and-sets-new-standard/ Transmission of 11.51 terawatt hours from sea to land accounts for a good 15 percent of total wind power generation in GermanyTenneT is investing more than 10 billion euros in new technical standards using 2 gigawatt connections at 525 kV voltage level
  • Transmission of 11.51 terawatt hours from sea to land accounts for a good 15 percent of total wind power generation in Germany
  • TenneT is investing more than 10 billion euros in new technical standards using 2 gigawatt connections at 525 kV voltage level
  • In the first half of 2020, the amount of wind energy transmitted onshore by the transmission system operator TenneT from the North Sea rose to 11.51 terawatt hours (TWh)*. This corresponds to an increase of 21.1 percent compared to the first half of 2019 (9.51 TWh). Power transmission from the North Sea accounts for a good 15.6 percent of total wind power generation in Germany, which reached 73.7 terawatt hours in the first half of 2020.

    “The expansion and integration of offshore wind energy is of central importance for the European energy transition,” says TenneT COO Tim Meyerjürgens, “With Borssele alpha and – from mid-August – Borssele beta, we have now also successfully completed the first two offshore connections in the Dutch North Sea. We are making consistent progress in the key areas of innovation, standardisation and cost efficiency. Ever since TenneT set the standard for plastic-insulated direct current cables at 320 kilovolts (kV) in the offshore sector around ten years ago, we have been defining a new global benchmark for the future with our 525-kV direct current subsea cable system and its transmission capacity of two gigawatts (GW).”

    This development programme is aimed at creating a standardised cable system that TenneT will be able to use in the five projects BalWin1, BalWin2, BalWin3 (German North Sea) and IJmuiden Ver alpha and beta (Dutch North Sea) by 2030, as well as in future projects with the same power and voltage. This will reduce costs, increase the security of supply and, at the same time, minimise the environmental impact.     

    “We have an investment programme of around 20 billion euros earmarked for connecting offshore wind energy in the Netherlands and Germany by 2030. More than half of it will be assigned to the new 2-gigawatt standard,” says Meyerjürgens. TenneT currently has 14 offshore grid connections in operation, two of them in the Dutch North Sea (including Borssele beta) and twelve in the German North Sea. At 7,132 megawatts (MW) in the German North Sea alone, TenneT’s connection capacity already exceeds the federal government’s target for 2020, which is                         6.5 gigawatts for the North and Baltic Seas in total. In the Dutch North Sea, TenneT is set to achieve 1,400 megawatts of connection capacity by mid-August 2020. By 2030, TenneT’s offshore grid connection capacity will increase to around 17 gigawatts in Germany and 9.6 gigawatts in the Netherlands.

    TenneT is also following the various hydrogen-related projects and initiatives with great interest and welcomes them – especially when it comes to clarification of the legal framework. As far as the North Sea Wind Power Hubs proposed by TenneT are concerned, coupling power to gas/hydrogen has been explicitly included in the concept right from the start. The North Sea Wind Power Hub project is currently dealing intensively with the issue of power to gas/hydrogen and the timely installation of hubs, and is pushing ahead consistently with these topics and studies.

    In June, TenneT also made proposals to the EU and the Dutch and German governments to create an integrated energy system approach to the international development of offshore wind energy, including bespoke technology and regulations to facilitate the use of hybrid projects. “Alongside the standardisation of the HVDC technology that will be used in the future, we also need an internationally coordinated planning approach for diverse processes from spatial planning to regulation, as well as the issues of electricity market design and economic investment security,” explains Meyerjürgens.

    Additional figures

    In the German North Sea, the maximum infeed performance of offshore wind farms in the first half of 2020 was measured at 6,035 MW on 2 January. The capacity expansion of the offshore wind farms in the German North Sea brought this up to 6,679 MW by 30 June 2020. TenneT’s offshore transmission capacity in the German North Sea is 7,132 MW.

    The wind turbines in the Baltic Sea (50 Hertz grid area) generated 2.22 terawatt hours*) in the first half of 2020, making Germany’s total offshore yield 13.73 terawatt hours during this period*). With an additional 59.67 terawatt hours*) of generated onshore wind energy, the total yield is thus 73.7 terawatt hours*).

    For comparison, here are the full-year figures for 2019: German North Sea: 20.25 TWh. This would be enough, for example, to cover the annual consumption of more than six million households. German Baltic See: 4.13 TWh; onshore: 99.14 TWh.

     

    *) Financially subsidised electricity in accordance with the German Renewable Energy Sources Act (EEG), without other direct marketing; using 2020 as the preliminary actual value. The energy volumes produced onshore for the months of May and June 2020 are incorporated as preliminary estimated values.

    • Investors show keen interest: issue 2.5 times oversubscribed
    • Green Hybrid further strengthens TenneT' s balance sheet
    • Largest corporate green debt issuer in the Netherlands, with over EUR 9 billion issued 

    TenneT Holding B.V. (rated A3/A-) yesterday successfully priced a Green Hybrid Bond issue of EUR 1 billion with a coupon of 2.374% and a non-call period of 5.25 years. The issue will further strengthen TenneT' s balance sheet as it will receive 50% "equity credit" from the credit rating agencies. Proceeds will be used to invest in green projects in the Netherlands and Germany to connect large scale offshore wind to the onshore electricity grid and to enhance the onshore transmission capacity for renewable energy. The transaction was supported by ten banks: BNP Paribas and HSBC as joint structuring advisors and joint lead managers, Deutsche Bank and ING Bank as joint lead managers and ABN AMRO, Commerzbank, Lloyds Bank, NatWest Markets, Rabobank and SMBC Nikko as passive bookrunners.

    Investing in green energy

    In order to implement the sustainable energy policies of the Netherlands and Germany, drive the energy transition and carry out large-scale maintenance work on our high-voltage grids, TenneT' s annual investments are expected to grow from approximately EUR 2 to 3 billion today to approximately EUR 4 to 5 billion within the next five years.

    The majority of TenneT' s investments are directly related to the increase in renewable energy sources, such as wind and solar energy. In the period up to 2030, TenneT expects to have realized approximately 28 gigawatt (GW) of connection capacity for offshore wind farms in the Dutch and German parts of the North Sea, transmitting an amount of electricity sufficient to power 38 million households for a full year.

    • TenneT and TransnetBW invest approx. €2 billion in state-of-the-art cable technology
    • Contracts awarded to NKT and Prysmian
    • Major step closer to implementation for SuedLink

    Bayreuth/Stuttgart/Würzburg, 29 June 2020

    Transmission system operators TenneT and TransnetBW are driving the SuedLink energy transition project further forward. In parallel with the ongoing approval procedures, both companies have opted for plastic-insulated 525 kV underground cables. Contracts to deliver and lay the underground cables have been awarded to NKT GmbH & Co. KG and Prysmian PowerLink S.r.I. The combined value of the contracts is approx. €2 billion.

    “In the future, SuedLink will form the backbone of the energy transition in Germany. With the commissioning of the direct current ground cables, we are now moving from the planning stage to the realisation of this important power link,” says Tim Meyerjürgens, Managing Director of TenneT. About 2,500 km of cable will be needed to cover the planned four-gigawatt transmission capacity between Schleswig-Holstein, Bavaria and Baden-Württemberg.

    Following pre-qualification tests involving a number of cable manufacturers, TenneT and TransnetBW opted to use plastic-insulated underground DC cables with a voltage level of 525 kV for SuedLink, since the high-tension cables can transmit more power. Another benefit: only half as many cables are required compared to a 320 kV solution. Lower transmission losses and less civil engineering work mean the SuedLink cables will not only offer financial benefits but also have minimal impact on the landscape. “We are very happy to be able to apply this innovative and environmentally benign technology for SuedLink,” comments Dr Werner Götz, Chair of the Executive Board of TransnetBW.

    The technical suitability and operational safety of the 525 kV cables were first tested during a multi-year testing phase involving several cable manufacturers. The cables were repeatedly exposed to various stresses under realistic conditions, and the success of these pre-qualification tests showed that this technology is both reliable and safe.

    The two cable manufacturers will be responsible for all aspects of the work, including design, manufacture, logistics and installation of the underground cables in the prepared channels and crossings, assembling the junction boxes and terminals, and the final high-voltage testing of the cable system. The cables are manufactured in accordance with the highest currently applicable quality and sustainability standards by NKT in Cologne and Karlskrona (Sweden), and by Prysmian in Gron and Montereau (France) and Pikkala (Finland). 

    About SuedLink

    With a length of approximately 700 kilometres and an investment value of €10 billion, SuedLink is the largest infrastructure project for the energy transition in Germany. The project is currently mid-way between planning at a federal level and the formal public planning procedure. TenneT submitted an application for plan approval for the first, northern, section at the beginning of 2020. The remaining sections will follow during the year.

    TenneT is responsible for the northern section of the SuedLink cable route, as well as the converters in Schleswig-Holstein and Bavaria, while TransnetBW is responsible for the southern section of the cable route and the converter in Baden-Württemberg.

    The study was carried out by the Transmission System Operators (TSOs) of the seven countries cooperating in the Pentalateral Energy Forum (PLEF): Austria, Belgium, France, Germany, Luxembourg, the Netherlands and Switzerland. The PLEF is the framework for regional cooperation in Central Western Europe towards improved electricity market integration and security of supply. The study, which aimed to investigate the generation adequacy within the PLEF region up to the medium term (2025), is an important result of TSO cooperation at regional level.

    De results from the PLEF GAA are in line and confirm the conclusions of TenneT's most recent national adequacy report (Rapport_Monitoring_Leveringszekerheid_2019), which states that generation adequacy in the Netherlands will meet the standard until 2025. There is sufficient production capacity in the Netherlands within this period to meet national electricity demand. Thanks to TenneT’s interconnections with neighbouring countries, the standard of four hours per year (shortage of electricity supply compared to demand) is not expected to be exceeded, even in extreme scenarios.

Participation by the German State in TenneT is the government's preferred scenario, which has led to the conclusion that a minority stake of the German State in TenneT Holding or TenneT Germany will be worked out. Holding on to the advantages of a one, cross border TenneT

    In a letter to the Dutch Lower House of Parliament (19 May 2020), Finance Minister Hoekstra presented his preferred scenario for meeting TenneT's capital requirement as a result of rising investments (due to the energy transition) and persistently low interest rates. Participation by the German State in TenneT is the government's preferred scenario, which has led to the conclusion that a minority stake of the German State in TenneT Holding or TenneT Germany will be worked out.

    According to the government, this scenario fits best within the formulated political objectives and preconditions. The objectives are holding on to the advantages of TenneT’s cross border steering and lowering the financial risks for the Dutch state that the German operations involve. The preconditions consist of guaranteeing the public interests and national security. TenneT is cooperating closely with the shareholder and supports this next step, which is based, among other things, on the advantages of one, cross-border operating TenneT offers society and economy.

    The Dutch and German governments are exploring all the possibilities, not just the financial ones

    The Dutch and German governments have also signed and published a Joint Declaration of Intent (JDI) to stress the mutual political interests. The JDI includes arrangements to expand collaboration on energy between Germany and the Netherlands and to continue exploring whether German state participation in TenneT is an option, bearing in mind that each state will only contribute equity to finance TenneT's investments in its own country. Both countries have agreed, with TenneT’s consent and cooperation, to hold exclusive talks and negotiations in the coming months to work out the details.

    More intensive collaboration on grid development, system integration and innovation

    Over the past decade TenneT has already achieved major socio-economic benefits in its cross-border cooperation, such as greater security of supply, lower and less volatile electricity prices and many lessons learned in our sustainable offshore and onshore investments, leading to lower costs for society. TenneT knows like no other that the energy transition will be more successful and more efficient if we stop limiting our thinking to national boundaries and create yet more space for (international) collaboration and innovation. This is why TenneT strongly supports the intention of both the German and Dutch governments to intensify collaboration on grid development, system integration and innovation. In fact, if the two governments, who will perhaps both soon be shareholders in a single, cross border and integrated TenneT, work more intensely together, the energy transition in Northwest Europe could prove cost efficient. TenneT is preparing for its pioneering role in the energy transition, and closer collaboration with the German government, both in financial terms and in terms of the energy policy, is very much a part of that.

    TenneT with complete top team in shape for the next phase of growth

    TenneT has been been busy getting our internal organisation in order over the past twelve months, and we are proud of the result. Like a team of elite athletes preparing for the European championships, the company has brought more focus to the strategy, set up a new organisation and processes to be able to grow further and initiated further development of TenneT's (leadership) culture with a focus on cooperation, courage and responsibility.

    By 1 July, TenneT will be as solid as a rock: a full team in in excellent condition. TenneT is pleased that this top team has a good balance of German and Dutch colleagues, male and more than 30 percent female colleagues and a good diversity of thinking from TenneT and from the market.


    The beginning of the negotiating stage, a careful process that needs time

    The letter to the Lower House and in particular the signing of the JDI mark the beginning of an intensive period of trilateral talks and negotiations between TenneT and the Dutch and German governments. Matters like the price and terms of a possible transaction will need to be discussed. In addition to the valuation of the company, it also concerns, for example, the level at which the German State will invest if everything goes ahead: TenneT Holding or TenneT Germany. All parties are aiming for an outline agreement before the end of the year. Of course, TenneT will be making an important and active contribution to this process. There is frequent and good contact with TenneT's  Dutch shareholder (the Ministry of Finance), the Dutch energy policymaker (the Ministry of Economic Affairs and Climate) and the German government. In doing so, TenneT will continue to give the highest priority to its pivotal role in the energy transition and the interests of all its stakeholders: its customers, communities, business partners, bondholders and employees alike.

    Because this process is complex and beset with uncertainties, TenneT has decided to issue Green Hybrid Bonds before the end of the year, in accordance with our financing plan. Fifty percent of these Green Hybrid Bonds will be regarded as equity. By doing so, TenneT can ensure that its good credit rating is guaranteed for 2021; it will give the company time to follow the process through carefully. Moreover, in his letter to the Lower House of Parliament, the Minister says that, if necessary, capital will be provided for both the Dutch and the German parts of TenneT to maintain the company’s credit rating, which means TenneT has a guarantee for 2022 too.

Together with the Executive Board, this new Senior Leadership Team will lead  TenneT through its next growth phase. 

    The organisation structure, which will become effective as per 1 July, is an important milestone in TenneT's change program 'Transforming TenneT'. Last year TenneT started this program to bring more focus in its strategy, to design afunctional organisation and to create a company culture that will support the company's growth and its role in the energy transition in the Netherlands, Germany and their neighbouring countries.

    In 2019, TenneT hired more than 1000 employees in the Netherlands and Germany, and expects this increase to continue in 2020, despite the Corona crisis. In the next few years an estimated growth of 6%-7.5% is expected to realize the company's ambitions, investment agenda and growth.

    Manon van Beek, CEO of TenneT: "On 1 July TenneT's organisation will be solid as a rock, with a complete leadership team in top condition. We are happy that with this team we managed to find a good balance between German and Dutch colleagues, male and (more than 30%) female colleagues, as well as a diverse mind set from within TenneT as well as outside the company. The six senior leaders all gained extensive experience in international companies such as Siemens, Innogy and E.O.N. With the new integrated organisation we are well positioned to meet the major challenges of the European energy transition with confidence."

    With Transforming TenneT, the company anticipates on the necessity of a closer cooperation between grid operators and other parties in grid development, system integration and innovation. This is why the organisational set up includes new future-looking units such as Strategy & Partnerships, Digital & Process Excellence and Energy System Planning.

    Over the past ten years, TenneT managed to achieve substantial social-economic benefits with its cross- border organisational set-up , in terms of security of supply, harmonization of the price of electricity as well as lessons learned from its sustainable offshore and onshore investments. This has brought the Netherlands and Germany, both countries with an ambitious sustainability agenda, large societal (cost) benefits. The ambitions which have been laid out by the EU in its 'Green Deal' require an even more intensive cooperation across borders. With its basis in the Netherlands and Germany, TenneT is preparing to take a frontrunner role in the European energy transition. TenneT counts on a close cooperation with the Dutch State (TenneT's shareholder) as well asthe German State, in particular both ministries of Economic Affairs. TenneT is engaged with both the Dutch State and the German State regarding  its need for equity in view of TenneT's large investments in high- voltage infrastructure on land and at sea related to the energy transition in the Netherlands and Germany.

    • 50Hertz and TenneT project reaches important milestone
    • NKT and Prysmian receive major order for around 1,000 kilometres of underground cables

    Bayreuth/Berlin, 5 May 2020 – One of the energy transition's major grid expansion projects is taking another important step forward. The underground cable suppliers for the SuedOstLink direct current connection, which is around 500 kilometres long and will be between Wolmirstedt near Magdeburg in Saxony-Anhalt and Isar near Landshut in Bavaria, have been confirmed. The transmission system operators TenneT and 50Hertz, who are jointly implementing the direct current connection, have now awarded the contract to two cable manufacturers.

    The contract went to NKT GmbH & Co. KG and Prysmian PowerLink S.r.I. In addition to manu-facturing, it also includes laying the underground cables. SuedOstLink requires around 1,000 kilometres of the plastic-insulated underground cable for a voltage of 525 kilovolts (kV). The connection will have a transmission capacity of two gigawatts.

    "The underground cables are the heart of SuedOstLink. By placing the order for the underground direct current cables, we have made good progress in implementing this important connection for the energy transition", emphasized Tim Meyerjürgens, Managing Director of TenneT. "We will use the innovative, plastic-insulated 525 kV underground cables for the first time worldwide and will thus set new standards in technology and the reduction of environmental impact."

    With the higher voltage level, the cables can transmit more power than the conventional 320 kV cable systems. This requires fewer cables to transmit the same power; the route can be narrower and the necessary civil engineering work during the construction phase will decrease. This significantly reduces the impact on the environment.

    "The extensive tendering process that started in 2018 ends with the award of the contract; the two successful companies can now go into production and plan the cable laying beginning in 2022. This is a good signal for the SuedOstLink joint venture project as well as for the energy transition across Germany and Europe", said Dr. Frank Golletz, Technical Director at the transmission system operator 50Hertz.

    Orders involve extensive work

    The companies commissioned are represented in numerous international projects. In Germany, their extra-high voltage cables connect a number of wind farms in the North and Baltic Seas to the German onshore transmission system grid. NKT is supplying the underground cables for the northern part of the SuedOstLink project through Saxony-Anhalt, Thuringia and Saxony. Prysmian PowerLink produces the underground cables for the Bavarian SuedOstLink section. The orders placed include the design, manufacture, delivery and laying of the underground cables, as well as the installation of the connecting sleeves and terminations and the final high voltage test of the cable system. In addition, the suppliers provide support in the detailed routing, specifically in determining the individual cable lengths and the locations of the connecting sleeves.

    All bidders had to demonstrate the quality of their cables in an extensive prequalification test. The test simulated the operational load for the planned total operating time of around 40 years within a twelve month period. On the basis of the positive test results, the transmission system operators decided on the system voltage of 525 kV last year. Until then, a voltage of 320 kV was included in the planning as an alternative option.

    Important connection for the energy transition

    SuedOstLink is currently undergoing the planning approval procedure. At the end of this procedure, the approval authority - the Bundesnetzagentur (Federal Network Agency for Electricity, Gas, Telecommunications, Post and Railway) - determines the exact course of the underground cable route. SuedOstLink should be completed by the end of 2025.

    TenneT and 50Hertz are investing around five billion euros in the SuedOstLink project. The investments are amortised over 40 years. At the same time, SuedOstLink will help to reduce the costs of grid stabilisation measures, which are borne in full by electricity consumers. These costs are around 1.3 billion euros annually nationally. Grid stabilisation measures are necessary because the existing power grid is not designed for the growing share of renewable energy resources in power generation. With connections such as SuedOstLink, these costs are reduced because they will transport decentrally generated wind and solar power flexibly and safely to the customers.

    SuedOstLink is a European Union "project of common interest" (PCI) and is funded within the "Connecting Europe" framework. Since 2012, its needs have been repeatedly confirmed in grid development plans and the Federal Requirements Plan Act. SuedOstLink will connect the north-eastern German states, with their high wind and solar power generation levels, to important industrial regions and consumption centres in Bavaria, and is crucial to further improve supply security, expand renewable energy sources and to achieve the 2030 and 2050 climate protection goals.

Batteries from millions of households will stabilise the electricity grid in the future. Important innovation for the success of the energy transition.
  • TSOs TenneT, Swissgrid and Terna are developing a European blockchain platform.
  • Batteries from millions of households will stabilise the electricity grid in the future.
  • Important innovation for the success of the energy transition.
  • Together with TenneT (Germany and the Netherlands), Swissgrid (Switzerland) and Terna (Italy), four of the largest European transmission system operators are now jointly developing a cross-border blockchain platform - Equigy. This will enable millions of European households and owners of e.g. electric vehicles to actively offer the flexible capacity of their cars and house batteries on the energy markets to stabilise the electricity system and thus earn money from the energy transition.

    The energy world is changing rapidly, both on the supply side and on the demand side. As the electricity system increasingly relies to a large extent on sustainable and fluctuating electricity generation, there is a need for new sources of flexibility to keep the grid in balance. Many TSOs are traditionally dependent on fossil fuel thermal power plants for this purpose. At the same time, energy consumption is also changing due to the increasing demand for electric cars, heat pumps and solar panels. All this leads to fluctuations in supply and demand.

    "Now that the conventional power stations are closing, we are preparing for a future in which we are largely dependent on consumers with their electric cars, home batteries and heat pumps to stabilise the grid reliably, sustainably and cost-effectively. In order for all these devices to work together to balance the grid, the Equigy platform provides an important technical basis. With this platform, data can be exchanged between the devices, market players and grid operators. This means that everyone will soon be able to help realise the energy transition and also benefit financially from it," says TenneT CEO Manon van Beek.

    "Equigy originated from European cooperation. In a common European market we will have to develop solutions together. We already have the same sockets. It would be a shame and unnecessarily expensive to develop different systems. In view of the European Union's ambitious climate objectives, this platform is one of the innovations needed to guarantee the security of energy supply even after the abandonment of fossil fuels".

    The Equigy platform will initially be launched in Germany, the Netherlands, Switzerland and Italy. The partners expect other European network operators to join as well.  

    About the Equigy platform:

    In tomorrow's energy world, millions of small decentralised electricity producers, consumers and storage facilities such as electric vehicles, domestic batteries and heat pumps will help to cope with grid bottlenecks and balance fluctuations between generation and consumption. In this way, they take over tasks that today are mainly carried out by large power plants such as coal- and oil-fired power plants with a capacity of several hundred megawatts.

    For millions of decentralised small storage units in households in the one to two digit kilowatt range across Europe to be able to offer their free capacity for grid stabilisation, automated processes and IT solutions are needed that make this possible in a simple, fast and cost-effective way. With the Equigy platform, the TSOs create the conditions for this. As an open source solution, the platform will be available free of charge.

    The platform uses blockchain technology which allows transactions from millions of individual systems to be carried out securely, cost-effectively and transparently. Unambiguous laws and regulations enable consumers, businesses and manufacturers to market the flexible capacity of electric vehicles, domestic batteries and heat pumps easily and location-independently in all participating countries, thus simplifying access to the electricity market. At the same time, all local/regional flexibility platforms can be connected to the Equigy platform so that as much flexibility as possible can be bundled.

    TenneT has already gained a great deal of experience in numerous pilot projects involving the use of decentralised flexibility from domestic batteries and e-vehicles, such as the collaboration with Sonnen and Vandebron and participation in the 'Bidirectional Charging' consortium with BMW.

However a 2GW offshore grid connection is currently not existing. Innovation is needed and TenneT invited cable suppliers to develop these 'next level' submarine cable systems.

    TenneT contracted 8 cable suppliers

    TenneT has contracted 8 cable suppliers to develop a new standard for a submarine cable system. This new cable system is required for the planned 2GW offshore grid connections in the Netherlands (IJmuiden Ver) and in Germany (LanWin and Balwin) which set a new standard for connecting offshore wind farms. A 525 kV HVDC extruded submarine cable system with a 2GW capacity is currently not implemented in any project worldwide. The development programme should result in a certified cable system which TenneT can apply in the IJmuiden Ver, BalWin and LanWin projects as well as projects using the same power output and voltage. This will reduce costs and minimise spatial impact.

    New standard in submarine cable systems

    The participating suppliers are:

    • Hellenic Cables SA (Greece)
    • LS Cable & System Ltd. (Korea)
    • Nexans Norway AS (Norway)
    • Ningbo Orient Wires & Cables Co., Limited (NBO) (China)
    • NKT HV Cables AB (Sweden)           
    • Prysmian Powerlink Srl (Italy)
    • Sumitomo Electric Industries, Ltd (Japan)
    • Zhongtian Technology Submarine Cable Co., Limited (ZTT) (China)

     

    "It is very positive to see that multiple international cable suppliers are participating in this programme. It shows that the sector is keen to innovate together to produce a new standard for submarine cable systems substantially reducing cost for society," says Marco Kuijpers, Director Offshore Projects at TenneT.

    Development programme

    To link 2GW offshore grid connections to the onshore grid system, a suitable (new) certified cable system is required. This cable system will connect a 2GW platform and a land station. To transport the required 2GW power, a submarine cable system operating at a voltage level 525 kV DC using extruded insulation types is needed. All the participating cable suppliers will develop and test the cable system within the time frame for the 2GW projects and TenneT will be in close contact with them during the entire process. TenneT expects that the development of the 525 kV DC submarine cable system will result in a certified cable system in spring 2022. Following this path, the development programme enables both the developers and TenneT to deliver a new cable system cost efficiently and in time.

    Less spatial and environmental impact 

    The need to develop this submarine cable system is derived from the expectation that it will reduce manufacturing and installation costs. Not only for the cable system itself but also for the entire grid concept, including the High Voltage Direct Current (HVDC) offshore platform and the HVDC land station. TenneT expects the bundled installation to achieve significant cost reductions. Besides reducing installation costs, it is also expected to reduce dredging costs because all cables can be put in a single trench. This approach also results in fewer platforms and land stations, which is not only interesting in financial terms but also ensures that TenneT causes lower emissions and has less spatial and environmental impact.        

    Taking the next step in the energy transition

    TenneT is constantly looking to take steps in the energy transition that can contribute to the offshore targets of safely and cost effectively transporting offshore wind farms. Given the increase in size of the Ijmuiden Ver Wind farm and the distance to the nearest connection point, it was decided to apply the 'new' 525 kV 2GW grid concept. This is a logical move after installing eight standard AC connections in capacity of 700 MW, bringing the total installed capacity offshore wind connected by TenneT to 9.6 GW in the Netherlands alone in 2030. TenneT already has extensive experience with DC projects in Germany.

Vattenfall and TenneT have signed an agreement for the offshore grid connection for wind farm Hollandse Kust Zuid 3&4, marking a key milestone for this project. Last year, both parties also signed an agreement for Hollandse Kust Zuid 1 & 2.

    "This is an important milestone, and I'm pleased that the contracts could be signed so quickly – just nine months after winning the bid", says Catrin Jung, Head Offshore Wind at Vattenfall. "We're looking forward to work with TenneT on Hollandse Kust Zuid 3 & 4. The combined wind farms of Hollandse Kust Zuid will be able to cover the total energy demand of between two and three million households, which makes it a major driving factor behind the transition to renewable energies in the Netherlands."

    "The development of an offshore grid is well on track," states Marco Kuijpers, Director Offshore at TenneT. "Hollandse Kust Zuid is the second wind farm site to which we will be providing access in the form of two standardised AC connections of around 700 MW each. We are looking forward to working with Vattenfall as we develop HKZ 3 & 4."

    Offshore grid
    The Dutch government has assigned TenneT as its offshore grid operator. The Energy Agreement sets out that TenneT will install 1,400 MW of offshore grid connections for the Hollandse Kust Zuid site, and provide for additional flexible transport capacity.The plan is for operations on the connection for Hollandse Kust Zuid 1 & 2 to commence in 2021. The offshore grid connection for plots 3 & 4 will follow in 2022. All plots will be developed by Vattenfall.

    The grid connection for Hollandse Kust Zuid consist of two offshore transformer platforms, each with two 220 kV AC cables per platform. Electricity is transferred to onshore infrastructure via these cables. TenneT is building a new onshore transformer station and is expanding the 'Maasvlakte 380 kV' high-voltage station. At this high-voltage station, offshore wind energy is connected to the south ring of the Randstad 380 kV line operated by TenneT. Wind energy is then transferred to power consumers via the national high-voltage network.

    About SIDC:


    The SIDC solution is based on a common IT system with one Shared Order Book (SOB), a Capacity Management Module (CMM) and a Shipping Module (SM). It allows for orders entered by market participants for continuous matching in one bidding zone to be matched by orders similarly submitted by market participants in any other bidding zone within the project’s reach as long as transmission capacity is available. The intraday solution supports both explicit allocation on the Croatian/Slovenian and French/German borders (as requested by the respective National Regulatory Authorities, NRAs) and implicit continuous trading. It is in line with the EU Target model for an integrated intraday market.

    European-wide intraday coupling is a key component for completing the European Internal Energy Market. With the rising share of intermittent generation in the European generation mix, connecting intraday markets through cross-border trading is an increasingly important tool for market parties to keep positions balanced. The purpose of the SIDC initiative is to increase the overall efficiency of intraday trading.

Grid transformer platform to be sailed out to sea on 22 March 2020.

    The superstructure (topside) of TenneT's offshore transformer platform for the Borssele III, IV and V wind area is ready for its sea voyage. Right on schedule, the offshore power socket, Borssele Beta, will provide access to the wind energy generated by the offshore wind farms Borssele III, IV and V that are still under construction, and bring it onshore starting in 2020.

    The 700 MW offshore station is expected to be operational according to schedule on 1 September. From that point onwards, the wind farm being constructed approximately 22 km from the coast of the Province of Zeeland by the Blauwwind consortium will be plugged into this power socket. The electricity generated by the offshore Borssele III, IV and V wind farm will subsequently be brought onshore to the high voltage substation in Borssele by means of two 67-kilometre long cables. The platform was built by HSM Offshore in Schiedam (NL).

    Marco Kuijpers, Director Offshore Projects: “With this platform, the offshore grid that TenneT is building in the Dutch North Sea is definitively taking shape. Borssele Beta is the second offshore grid connection built by TenneT. Over the coming eight years we will build a new offshore connection every year. I am proud that we are able to make such a significant contribution to the energy transition in which offshore wind energy plays a crucial role.”

    Sandor Gaastra, DG Climate and Energy, Ministry of Economic Affairs and Climate Policy (EZK): “The construction of the Dutch wind farms in the North Sea is well on track. This is in part due to the coordinated construction of an offshore electricity grid by TenneT. The second ‘offshore power socket’ will transport approximately 2.5% of the electricity used in the Netherlands from the wind farm to the mainland.”

    Sail-out

    On the 22th of  March, the pontoon carrying the topside will sail through the New Waterway in the direction of the Borssele III and IV wind area. At this site, a crane vessel will place the topside on top of the substructure (jacket).
    The superstructure (topside) consists of three interior levels (main deck, utility deck, control deck) and an outer deck (roof deck). The topside is 25 metres high, 58 metres long and 32 metres wide. The topside weighs 3,650 tonnes.

    Ecological and navigational monitoring station

    The Borssele Beta transformer platform also contains a monitoring station with various monitoring systems, such as nautical radars, meteorological systems (for wind, precipitation, clouds and temperature) and ecological monitoring systems for birds and bats. A similar Maritime Information Provision Service Point (MIVSP) is being installed on every offshore transformer platform by the Directorate-General for Public Works and Water Management (Rijkswaterstaat) in cooperation with TenneT. These monitoring stations will be used to collect unique and detailed information along the entire Dutch coastal area. In addition to the Coastguard, other organisations, such as port authorities, universities, the Dutch Meteorological Office (KNMI), and wind farm operators will make use of this data.


     

    Important step in energy transition

    Forty percent of the Netherlands’ electricity supply will come from offshore wind farms by 2030. As such, offshore wind energy is an important pillar of the energy transition. The Netherlands is on track towards achieving its climate objectives. TenneT is making an important contribution to the energy transition by installing offshore wind farms on schedule and within budget. Borssele Alpha was delivered on time (September 2019) and Borssele Beta now also will be installed offshore on schedule to connect the wind farms that are now being constructed. The Borssele III and IV wind farms will have a total capacity of 700 megawatts (MW). This corresponds to the electricity generation requirements of approximately one million households. The power will be connected through TenneT’s offshore Borssele Beta connection to the Borssele high voltage substation, from which it will be distributed to the onshore grid. TenneT will connect the wind farms off the coast of the Zeeland, Zuid-Holland and Noord-Holland provinces and the area above the West Frisian Islands the same way. Eight times over, TenneT will use the same 700 MW transformer platforms that are located close to the wind farms, and the same type of cable connection to the coast. This standardisation will allow these projects to be completed more efficiently, more quickly and more economically.

    9,600 MW wind

    In addition to the 3.5 GW set out in the ‘Roadmap for offshore wind energy’ (2015), TenneT will connect another 6.1 GW of offshore wind energy to the Dutch high voltage grid in accordance with the ‘Roadmap for offshore wind energy 2030’ (2019). Up to and including 2026, TenneT will install eight standard alternating current (AC) connections, each with a capacity of 700 MW. Starting in 2027, larger wind farms will be built further away from the coast in the IJmuiden Far wind energy region. Given the large capacity (2 GW per connection), and to limit the loss of energy during transport, TenneT is installing this connection as a direct current (DC) connection.

    By 2029, a total of 9,600 MW in wind energy will be connected

    • Social acceptance of new infrastructure, availability of equity financing and availability of the supplier market are crucial to TenneT's pivotal role in the energy transition.

     

    TenneT's efforts to drive the energy transition, one of its strategic priorities, are increasingly focused on innovation, optimisation of the current high-voltage infrastructure and close cooperation with stakeholders like governments, society, other grid operators and market parties. This is stated in the 2019 Integrated Annual Report that was published today by the Dutch/German transmission system operator TenneT. In line with the energy policies and national climate targets in TenneT's home countries, the Netherlands and Germany, TenneT also stepped up its investments in the energy transition in 2019.

    Clear strategic direction defined

    The report highlights TenneT's progress on a renewed strategy adopted in 2019, based on four pillars: Driving the energy transition, Maintaining security of supply, Energising our people & organisation and Safeguarding our financial health. In 2019 TenneT also posted solid financial results, to some extent affected by less favourable regulation particularly in Germany. A stable development of the profitability of TenneT's regulated activities is necessary for carrying out its extensive investment programme for the energy transition in the years ahead.

    Manon van Beek, CEO TenneT: "For TenneT, 2019 was both a successful and a challenging year. In 2019 we started the internal process for 'changing for growth' to prepare TenneT for its central and increasing role in the European energy transition and a new energy system. We have now successfully fully integrated the structure of our cross-border organisation, including the creation of several hundreds of new jobs across the company. We can be proud of that. The same applies to the availability of our high-voltage grids which improved slightly to 99.9998 percent, keeping our grids among the most reliable in the world. Financially, we delivered a solid performance in line with the expectations of our capital providers. Our EUR 3.1 billion investments are supporting the energy policies in the Netherlands and Germany. We have made great strides again in pursuing our ambition to achieve a sustainable energy future for everyone. Not only in realising and developing new onshore and offshore connections, but also by the required far-reaching international cooperation and working on innovations in close coordination with relevant stakeholders."

    KEY ACCOMPLISHMENTS IN 2019 DRIVING THE ENERGY TRANSITION

    Approximately one sixth of TenneT's total investments in 2019 were allocated to the maintenance of the existing high voltage grids; the other part was earmarked for newly built projects and grid expansions. A number of important projects to maintain the high security of supply and to drive the energy transition were completed or showed good progress in 2019.

    Unlocking new sources of renewable energy

    In 2019, TenneT already met and even exceeded the German government’s 2020 6.5 GW expansion target for sustainable North Sea and Baltic Sea wind power. BorWin 3, TenneT's ninth offshore direct current connection, has been commissioned. DolWin5, DolWin6 and BorWin5 are in development and will increase TenneT's transport capacity for wind farms in the German North Sea to almost 10 GW by 2025. After 2025 TenneT additionally plans more than 6.5 GW of transmission capacity to be installed by 2030. So TenneT is well prepared to meet future offshore goals as Germany's northern states and federal government want to more than double the country's installed offshore wind power capacity (North Sea and Baltic Sea) within ten years with a new expansion target of 20 GW by 2030, instead of the earlier goal of 15 GW.

    Borssele Alpha, TenneT's first alternating current (AC) offshore platform on the Dutch part of the North Sea, was installed on schedule and is now ready for use. Another seven of these 700 MW standardized platforms will be delivered by 2027 for connecting future offshore wind farms to the onshore grid. The next offshore connection system, Borssele Beta, will be completed by 2020. TenneT expects to have realised a total of almost 10 gigawatts (GW) of offshore connection capacity by 2030 in the Dutch North Sea. For the IJmuiden Ver wind area TenneT expects to use two 2 GW converter platforms in combination with 525 kV cable. A world's first, this new standard saves on costs and ensures a smaller spatial footprint.

    Offshore wind has a major impact on the onshore grid

    The energy transition can only be successful if the growth of offshore wind energy and onshore solar energy is developed in an integrated way with onshore grid expansions.

    Important steps were taken in 2019 in the planning and licensing phase for SuedLink, the North-South connection in Germany. The preferred corridor for this 2 x 2 GW underground (DC) cable connection was presented followed by extensive stakeholder dialogues and approval procedures being started. This corridor is planned to run from Schleswig-Holstein to Bavaria and Baden-Württemberg. TenneT and fellow German TSO TransnetBW launched EU-wide tenders for the convertor stations, key components of the project.

    TenneT is working in Germany on more large-scale onshore high-voltage connections than ever before. No fewer than eight high-voltage lines are under construction, including Wahle-Mecklar (230 kilometres), Mittelachse and the Westküstenleitung, which transport large amounts of wind energy from the north to end users further south.

    After five years of construction, the 60-kilometre-long Randstad 380 kV North Ring connection was commissioned. The new transmission line delivers a reliable electricity supply to millions of households and companies in the Dutch Randstad region. Moreover, this power highway will provide the required transmission capacity for green electricity produced by North Sea wind farms. Other large projects in preparation or under construction are Zuid-West 380 kV Oost and West, Eemshaven-Vierverlaten and increasing the capacity of the national 380 kV ring.

    Energy transition only successful with a European approach

    With the 'green' COBRA cable, which became operational in September 2019, the Dutch and Danish markets are directly connected for the first time. Sustainable electricity for nearly two million households can now be efficiently imported or exported. The undersea cable of more than 300 km also ensures greater security of supply for society. The German and Norwegian markets will be connected to each other directly for the first time with the NordLink cable connection that is currently being built. It is expected that this over 600 km long interconnector will be ready for operation in 2020 and facilitate the exchange of 'green' power on a large scale.

    TenneT's international solution to meet Europe's climate objectives after 2030 has provided new insights. An extensive study by the North Sea Wind Power Hub consortium has shown that an internationally coordinated roll-out of multiple 'Hub-and-Spoke' projects -  combining wind power connections, coupling energy markets through interconnection and smart integration in the onshore energy grid, including power to gas – is technically feasible. It will also increase societal welfare and support security of supply.  Each 'Hub-and-spoke' project of 10 – 15 GW and either platform of island based will be part of a step-by-step approach, providing adaptability to balance scale, development times and environmental compatibility.

    INNOVATION TO IMPROVE GRID UTILISATION

    Because the societal cost associated with the energy transition are rising and the incorporation of large infrastructure projects into the living environment often leads to discussions and litigation, TenneT is also explicitly looking for solutions that do not necessarily require costly grid expansions. The company initiates and participates in a large number of initiatives to make smarter use of existing assets and use new technologies.

    TenneT, for example, is carrying out pilots with a number of large automotive companies and suppliers of home batteries to enable 'crowd balancing'. TenneT strongly believes in a future in which electric cars and home appliances, such as home batteries, are used to unlock flexibility in power supply and demand and thus contribute to balancing the grid. With Daimler (Mercedes-Benz Energy) and BMW TenneT started successful pilots showing EV-batteries can indeed make a significant contribution to grid stabilization and system reconstruction. A role previously reserved only for conventional power plants.

    The innovative InnoSys project is aimed at designing digital solutions that will ensure the existing capacity of the high-voltage grid can be better used for the significantly growing need of sustainable electricity transport. Such an automated grid control system could prevent additional grid investments.Another longer-term innovation project includes the development - together with Thyssen Gas and Gasunie Germany - of a 100 MW electrolysis plant that can deliver green hydrogen for industry in phases as from 2022 and can serve as storage of sustainable energy in the form of gas.

    FINANCIAL

    TenneT's financial results were in line with expectations. 2019 underlying revenue of EUR 4,084 million decreased with 3% compared to 2018. Underlying EBIT decreased from EUR 853 million in 2018 to EUR 768 million in 2019. Excluding special items, underlying EBIT decreased by 9% to EUR 749 million in 2019, mainly driven by a reduced regulatory rate of return on equity in Germany, due to the start of the new 5-year regulatory period, partly offset by a higher regulatory asset base due to investments.

    Investments & financing: equity financing challenges ahead

    Otto Jager, TenneT's CFO: "As a result of the sustainable energy policy in the Netherlands and Germany, our investments are expected to increase further. In order to keep the company financially healthy, we expect to need EUR 2 to 3 billion of additional equity in the next four years. A number of solutions are conceivable. Any solution needs to be flexible, scalable and must not split the company. We are in close consultation with our shareholder (the Dutch State) about the best way forward. Earlier in the year under review, our shareholder announced that it would present its vision to parliament in 2020."

    Capex (investments) totalled EUR 3,064 million in 2019, of which EUR 1,131 million in the Netherlands and EUR 1,925 million in Germany. As a result of these investments, the net interest-bearing debt position increased by 9% to EUR 9,500 million at 31 December 2019.

    Leading in sustainable financing

    TenneT values its position as a leader in sustainable finance. In January of 2019 TenneT received EUR 500 million of proceeds from its first Green Private Placement in the U.S., which demonstrates TenneT's ability to further diversify its sources of funding and investors to finance its substantial investment plans.

    In May, TenneT issued a European green bond in two tranches, of 11 and 20 years, totaling EUR 1.25 billion. This bond will be used for investments in the transmission of renewable electricity from offshore wind farms to the onshore grid. Four Dutch offshore projects are also part of the green debt-financed portfolio, which up to now also includes nine offshore projects in Germany. In November TenneT Holding B.V. refinanced its EUR 2.2 billion sustainable Revolving Credit Facility (RCF) and increased the principal to EUR 3 billion. With more than EUR 11 billion of green debt and sustainable funding available, TenneT is the largest corporate issuer of green debt instruments in the Netherlands.

    INVESTMENT OUTLOOK

    The energy policies adopted by the Dutch and German governments are strongly focussed on making the energy system more sustainable. In order to be able to implement these policies on time, TenneT expects to increase its investment level to EUR 4 to 5 billion annually in the coming years as a result of the phase out of coal- and nuclear power plants and the strong growth of offshore wind energy. The increase in annual investments is due, for example, to the German decision to increase the capacity of offshore wind farms from 15 GW to 20 GW. The Dutch government has also initiated a major expansion of offshore wind energy in 2030, which means that TenneT must have realised 9.6 GW of connection capacity for offshore wind farms in the Dutch part of the North Sea by that year.
    Other large onshore projects in the Netherlands are ‘Zuidwest 380 kV’, ‘Noordwest 380 kV’ and the upgrade of the national 380 kV ring. In Germany the largest projects are the long-distance, underground direct current connections called SuedLink and SuedOstLink, connecting the northern part of the country with the south.

    news-2041 Mon, 09 Mar 2020 14:09:00 +0100 TenneT partners with EIB to power new transmission connection for offshore wind energy https://www.tennet.eu/news/detail/tennet-partners-with-eib-to-power-new-transmission-connection-for-offshore-wind-energy/ EIB signs EUR 250 million loan agreement with TenneT to finance the 43km high-voltage transmission connection between Borssele and Rilland. High voltage connection upgraded in anticipation of connecting North Sea wind farms to the electricity grid and maintaining high security of supply This financing increases the total EIB commitment to TenneT projects to EUR 1.8 billion. EIB signs EUR 250 million loan agreement with TenneT to finance the 43km high-voltage transmission connection between Borssele and Rilland.

    High voltage connection upgraded in anticipation of connecting North Sea wind farms to the electricity grid and maintaining high security of supply

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

    The European Investment Bank (EIB) has signed a EUR 250 million loan agreement with TenneT Holding B.V. The financing will be used for the western section of TenneT’s “Zuidwest 380 kV” project, which will enable the transmission of rapidly growing amounts of offshore wind energy to users in the Netherlands and beyond. In its entirety, the Zuidwest 380 kV project also supports increased connectivity of European electricity markets. Specifically, the EIB financing will support the construction of a new 380 kV transmission line – combined with a 150 kV line for part of the route - from the substation at Borssele to a new substation at Rilland.

    One of the main reasons for the upgrade is the ongoing growth of offshore wind power generation capacity off the Dutch southwest coast, as part of the 1.4 GW Borssele Wind Farm Zone. The new grid connection will allow for the avoidance of congestion on the high voltage grid once the wind farms are in operation and will facilitate transfer of green, offshore electricity to demand centres.

    “The Netherlands’ ambitious targets for renewable energy generation require more investment in the transmission network.” stated EIB Vice-President Andrew McDowell. ”That’s why the EIB, as the EU Climate Bank, is pleased to support this project.”

    Otto Jager, CFO of TenneT added: "The switch from traditional fossil fuels to renewable energy sources is one of the biggest challenges the world is currently facing. It is an immense task for transmission system operators. This project in the southwest of the Netherlands will support us in maintaining our strong track record in the availability of our electricity grids. At the same time, this connection facilitates the integration of sustainable offshore wind energy into the Dutch electricity system."

    The EIB has increased its total lending commitment to TenneT to EUR 1.8 billion. The EIB commitments are provided for the upgrading and expansion of TenneT’s electricity transmission  networks in the Netherlands and Germany as well as interconnectors. Today's transaction underlines again the strong relationship between the EIB and TenneT.

    Background information:

    The European Investment Bank is the European Union's long-term loan institution. This bank is directly owned by the Member States - the Netherlands owns slightly more than 5% of the shares - and can therefore borrow very cheaply on the capital market. The EIB thus makes long-term financing available for solid investments to contribute to EU policy goals such as sustainable growth and job creation, as well as climate goals. In the past year, the EIB made nearly EUR 2.5 billion available for projects in the Netherlands, including care, SMEs and energy efficiency projects.

    TenneT is a leading European high voltage grid operator (Transmission System Operator (TSO) that has its most important activities in the Netherlands and Germany. With 23,000 kilometres of high-voltage connections, we ensure a reliable and secure electricity supply to the 41 million end users in the markets that we serve. With close to 5,000 employees, we achieve a turnover of 4.2 billion euros and a total asset value of 22 billion euros. TenneT is one of the largest investors in national and international onshore and offshore electricity grids. Our focus is on bringing together the North Western European energy markets and facilitating the energy transition. TenneT makes every effort to meet the needs of society by being responsible, engaged and connected.

    news-2039 Tue, 03 Mar 2020 11:51:00 +0100 Deep Dig-It Trencher buries cables more than 5 metres below the seabed to connect offshore wind farms https://www.tennet.eu/news/detail/deep-dig-it-trencher-buries-cables-more-than-5-metres-below-the-seabed-to-connect-offshore-wind-far/ Rotterdam, 6 March 2020 - TenneT is building the Hollandse Kust (South) offshore grid to the north of the Maasvlakte, to connect new wind farms. Four cables will have to be routed into the North Sea seabed for this. The cables have to be buried more than 5 metres in the seabed for the first ten kilometres of the offshore cable route, as to be able to cross the busy Rotterdam Maasmond shipping lane.  Rotterdam, 6 March 2020 - TenneT is building the Hollandse Kust (South) offshore grid to the north of the Maasvlakte, to connect new wind farms. Four cables will have to be routed into the North Sea seabed for this. The cables have to be buried more than 5 metres in the seabed for the first ten kilometres of the offshore cable route, as to be able to cross the busy Rotterdam Maasmond shipping lane. 

    For this specific job, Van Oord designed and built the Deep Dig-It trencher, a gigantic and remotely controlled trencher. Van Oord, being part of the Van Oord-Hellenic Cables consortium, is conducting final tests with this enormous machine in the Alexiahaven (harbour) today, in preparation for the actual installation of the sea cables in July.

    The Deep Dig-It is a so-called “Tracked Remotely Operated Vehicle” (TROV), which drives unmanned over the seabed, creating a deep trench for the cables, while simultaneously inserting the cables and then closing the trench again. Special about this new trencher is that it is the largest and most powerful machine in its’ class. The trencher weighs 125.000 kilos, is more than 17 metres long, well over 8 metres high, and 11 metres wide. The installed power is unrivalled and matches the equivalent of two Leopard tanks (2,500 HP), making it possible to bury cables into very hard soils. Next to the large power installed, the depth of burial that can be achieved by the trencher is unmatched: well over 5 metres. A lot of marine ingenuity has been put into the Deep Dig-It, with the development of this new trencher Van Oord responds to a changing offshore wind market and its’ latest demands. The Deep Dig-It will be controlled from Van Oord’s offshore installation vessel MPI Adventure, which is equipped with a crane that launches and recovers the Deep Dig-It into the sea.

    Hollandse Kust (South) offshore grid project

    TenneT awarded the Van Oord-Hellenic Cables consortium in 2018, to build the connection from land to sea for the Hollandse Kust (South) offshore grid project. The consortium is installing and burying the sea cables crossing the entrance to Europe’s busiest freight port, the port of Rotterdam. The 1,400 MW project will be completed in 2022: Alpha (700MW) in 2021 and Beta (700MW) in 2022, to deliver electricity for 1.6 million households. This offshore wind farm will thereby contribute significantly to the Dutch government’s target of having a total of 4.5 GW of installed offshore wind energy power by 2023. The Hollandse Kust (South) offshore wind farm is 22 kilometres off the coast of the Dutch province of Zuid-Holland. The sea cables connect the two offshore platforms with the Maasvlakte high voltage substation and the Randstad 380 kV South ring. Wind energy is then transported to electricity consumers across the country through the national high voltage grid.

    news-2043 Tue, 25 Feb 2020 14:40:00 +0100 Grid balancing with horticulturists, electric boilers and car batteries enabled by TenneT's mobile network in pilot project https://www.tennet.eu/news/detail/grid-balancing-with-horticulturists-electric-boilers-and-car-batteries-enabled-by-tennets-mobile-n/ TenneT is investigating the possibility of using decentralised (sustainable) electrical power to participate in the market to balance supply and demand on the Dutch high voltage grid. This is the market for so-called aFRR (automatic Frequency Restoration Reserve), also known as regulating power. A new type of data connection was used successfully for the first time in the aFRR pilot project: data communication between market parties and TenneT (on activation and measurements) achieved using TenneT's mobile network. This removed a major barrier to the supply of aFRR by (new) Balancing Services Providers (BSPs). TenneT is investigating the possibility of using decentralised (sustainable) electrical power to participate in the market to balance supply and demand on the Dutch high voltage grid. This is the market for so-called aFRR (automatic Frequency Restoration Reserve), also known as regulating power. A new type of data connection was used successfully for the first time in the aFRR pilot project: data communication between market parties and TenneT (on activation and measurements) achieved using TenneT's mobile network. This removed a major barrier to the supply of aFRR by (new) Balancing Services Providers (BSPs).

    The aFRR supply by Enova – one of the parties in the aFRR pilot – has shown that the necessary information can be exchanged with TenneT via its mobile network. The pilot parties Sympower and Next Kraftwerke will also soon follow.

    Energy Manager Arjan van der Spek of the Bergschenhoek Horticulture Cluster: ‘This is an excellent example of cooperation between TenneT and Enova that will let Dutch greenhouse horticulture contribute positively to keeping the electricity grid in balance. It also seems that we’re going to be better off financially, so let’s go for it!’

    Evaluation

    TenneT will monitor and evaluate the performance of its mobile network over the coming months. If the evaluation is successful, TenneT will make the data connection available to all BSPs interested in using it to supply aFRR as soon as possible.

    More active consumer role

    The energy market is changing. The urgency of sustainability and energy independence is spurring a significant growth in the (decentralised) generation of sustainable energy. Consumers are also playing an increasingly active role by generating their own electricity as prosumers. So the system is changing from a demand-driven one with centralised production, to a more supply-driven system with decentralised generation.

    TenneT is purchasing Ancillary Services to maintain the grid balance and is still dependent on large production units for this purpose. Because large-scale generation may no longer be available in the future, TenneT must also be able to procure it from small-scale decentralised generation and large-scale and small-scale demand response.

    TenneT is investigating how it can facilitate these developments. New market parties want to serve the Ancillary Services market as Balancing Service Providers (BSPs). But the product specifications are a barrier to the new entrants, for example those relating to data communication via leased lines. 

    Private mobile network

    aFRR delivery requires a real-time data connection with a maximum four-second delay (one second in the future). So far the only safe and reliable option has been the leased line. This is not a problem for large-scale production units, as they frequently already have a leased-line connection with TenneT for other purposes. But for new BSPs, especially those without a direct connection to the TenneT high voltage grid, the purchase of a leased line is a major barrier to entry into the aFRR market. This threshold has been lowered with the live operation of TenneT's mobile network.

    About balance and regulating power

    One of TenneT’s statutory tasks is to maintain the balance of the entire Dutch electricity grid. The demand for and supply of electricity must always be in equilibrium. TenneT achieves this by calling up a range of balance products, such as FCR, aFRR and mFRR. These are standardised product names across the EU.

    FCR is used to stabilise frequency disturbances in the entire (internationally) coupled high voltage grid, irrespective of disturbance. For keeping the realtime (supply and demand) balance of the Netherlands TenneT activates aFRR and mFRR. This could for example be used to support a power plant outage or an incorrect expectation of the amount of wind or solar energy within the Netherlands.

    Using alternative sources in the aFRR market is not always possible with current specifications and communication technology. TenneT’s aim for these pilots is therefore to investigate and, where possible, lower the barriers to the provision of regulating power on the basis of decentralised (sustainable) electrical power. TenneT will thus be able to ensure there will continue to be sufficient future suppliers and flexible capacity to balance supply and demand in the Netherlands.
