In the meantime the project has further extended its scope with the accession of Slovak members OKTE (NEMO) and SEPS (TSO). The Nominated Electricity Market Operators (NEMOs) and Transmission System Operators (TSOs) involved in the European Single Intraday Coupling (SIDC – formerly known as XBID) are pleased to announce that the intraday markets coupled by SIDC have grown significantly as a result of second wave go-live in November 2019. 36 million trades have been executed since first go-live in June 2018, with significant increases in traded volumes being seen - especially across the seven second wave countries - while the system continues to perform well. In the meantime the project has further extended its scope with the accession of Slovak members OKTE (NEMO) and SEPS (TSO).

Following second wave go-live on 19th November 2019 the NEMOs from the seven acceding countries have reported significant increases in traded volumes. In the first three full months of cross-border trading (December 2019 - February 2020) HUPX, the Hungarian NEMO, recorded average monthly volumes of roughly 75 600 MWh compared to 7 600 MWh during the same period one year before. In Slovenia, BSP Southpool, reported an increase of monthly average volumes from roughly 15 000 MWh to 85 600 MWh over the same periods last year. Volumes on the market of OTE, the Czech NEMO, further confirm the trend with an eight-fold increase in monthly volumes to roughly 400 000 MWh. CROPEX, the Croatian NEMO, states that 24 100 MWh are now traded monthly, compared to 6 300 MWh before go-live. Volumes on the market of TGE, the Polish NEMO, also show a significant increase with average monthly volumes now at around 95 000 MWh compared to 3 000 MWh before. Meanwhile OPCOM, the Romanian NEMO, recorded average monthly volumes of 59 700 MWh compared to 26 000 MWh in same period a year before, while IBEX, the Bulgarian NEMO, has experienced more than double the monthly volumes*. 

SIDC currently couples the continuous intraday markets of 22 countries: Austria, Belgium, Bulgaria, Croatia, the Czech Republic, Denmark, Estonia, Finland, France, Germany, Hungary, Latvia, Lithuania, Luxembourg, Norway, The Netherlands, Poland, Portugal, Romania, Slovenia, Spain and Sweden. A 3rd wave go-live, which will expand the continuous cross border trading of electricity to Italy and Greece, is expected by the first quarter of 2021.

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

news-2057 Thu, 12 Mar 2020 10:51:36 +0100 TenneT preparing to meet European energy system challenges https://www.tennet.eu/news/detail/tennet-preparing-to-meet-european-energy-system-challenges/ 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 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

  •  In 2019 TenneT invested EUR 3.1 billion  in the energy transition and security of supply (99.9998% grid availability in 2019)
  • TenneT is preparing the company to facilitate an annual investment portfolio of EUR 4 – 5 billion to drive the energy transition
  • Underlying revenue amounted to  EUR 4.1 billion; EBIT (excluding special items) amounted to EUR 753 million
  • 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.

EBIT, corrected for special items753826
Investments in fixed assets3,0642,253

 

 

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-2051 Tue, 10 Mar 2020 13:00:44 +0100 TenneT heeft nieuwe wintrackmasten leverancier voor de 380 kV hoogspanningsverbinding tussen Borssele en Rilland https://www.tennet.eu/news/detail/tennet-heeft-nieuwe-wintrackmasten-leverancier-voor-de-380-kv-hoogspanningsverbinding-tussen-borssel/ TenneT heeft de bouw van de helft van de wintrackmasten voor de aanleg van de 380 kV-hoogspanningsverbinding van Borssele naar Rilland gegund aan VDL Network Supplies. In april verwacht TenneT de bouw van de masten van de andere helft van het tracé te gunnen.  TenneT heeft de bouw van de helft van de wintrackmasten voor de aanleg van de 380 kV-hoogspanningsverbinding van Borssele naar Rilland gegund aan VDL Network Supplies. In april verwacht TenneT de bouw van de masten van de andere helft van het tracé te gunnen. 

Het traject is opgesplitst in twee werkgebieden. Het werkgebied ten westen van Willem-Annapolder (van Station Borssele tot aan Willem-Annapolder) en het werkgebied ten oosten hiervan (van Willem- Annapolder tot aan hoogspanningsstation Rilland). De aannemers voeren ieder de helft van dit werk uit. 

De opdracht aan VDL omvat de productie, levering en plaatsing van 104 wintrackmasten voor het tracé van Willem-Annapolder naar Rilland. De eerste werkzaamheden starten naar verwachting eind 2020.

Borssele-Rilland 380 kV

De 380 kV-verbinding is van groot belang voor het elektriciteitstransport vanuit Borssele. Op dit moment is de huidige verbinding vol en is onderhoud niet mogelijk. Daarnaast zijn in Borssele de aansluitingen van de geplande windparken op zee te vinden. Dit maakt het noodzakelijk om de transportcapaciteit vanaf landstation Borssele naar het Nederlandse hoogspanningsnet te vergroten. Verder is de nieuwe hoogspanningsverbinding  Zuid-West 380 kV West, inclusief een nieuw 380 kV-hoogspanningsstation bij Rilland, een belangrijke schakel in de verbinding met België. Op deze manier is de leveringszekerheid van elektriciteit gewaarborgd.

De aanleg van de 48 kilometer lange 380 kV-verbinding tussen de hoogspanningsstations Borssele en Rilland start na de zomer van 2020. Na ingebruikname (verwacht in 2022) is er een extra verbinding naast de bestaande verbindingen op dit traject. Het combineren van de nieuwe verbinding met een deel van de bestaande regionale 380 kV-verbinding en 150 kV – verbinding maakt 42 kilometer van die verbinding overbodig. In totaal zal 42 kilometer, 131 vakwerkmasten,  van de bestaande hoogspanningsverbinding worden afgebroken.<br style="margin: 0px; padding: 0px; box-sizing: border-box; " />De bouw van hoogspanningsstation Rilland voor het 380 kV-transport is afgerond. Deze opdracht is uitgevoerd door SPIE. Spie verzorgt ook de geleidermontage (ophangen van de stroomdraden) van de gehele verbinding.

<br style="margin: 0px; padding: 0px; box-sizing: border-box; " />Masten

De nieuwe hoogspanningsverbinding wordt uitgevoerd met wintrackmasten. Met hun ranke ontwerp spelen Wintrackmasten in op maatschappelijke en technologische ontwikkelingen en maken het mogelijk om optimaal gebruik te maken van de beschikbare ruimte in de omgeving. Een wintrackmast bestaat uit twee pylonen, waaraan de hoogspanningslijnen worden gehangen.

Eerder plaatste TenneT deze wintrackmasten masten al bij:<br /><br />

  • de nieuwe 380 kV-verbinding in de Randstad (Beverwijk-Bleiswijk-Wateringen)
  • het Nederlandse deel van de grensoverschrijdende 380 kV-verbinding Doetinchem-Wesel
  • en straks bij de aanleg van nieuwe 380 kV-verbinding in Groningen (Eemshaven-Vierverlaten)

 

Voor deze zomer verwacht TenneT het contract voor de civiele werkzaamheden te gunnen aan twee verschillende partijen. Dit gaat om het aanleggen van werkwegen, werkterreinen en mastfundaties voor de masten en het herstel van de grond na ingebruikname van de hoogspanningsverbinding

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.&nbsp; 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.

news-2054 Fri, 14 Feb 2020 14:36:00 +0100 Uitkomst onderzoek congestiemanagement Oosterwolde https://www.tennet.eu/news/detail/uitkomst-onderzoek-congestiemanagement-oosterwolde/ In de omgeving van 110 kV onderstation Oosterwolde in Friesland is sprake van een grote toename van gevraagd vermogen voor teruglevering. Die vraag is dusdanig groot dat het 110 kV netwerk die vraag niet kan absorberen. Uitbreiding van het hoogspanningsnet gaat meerdere jaren duren. Gedurende deze periode kan er sprake zijn congestie. In de omgeving van 110 kV onderstation Oosterwolde in Friesland is sprake van een grote toename van gevraagd vermogen voor teruglevering. Die vraag is dusdanig groot dat het 110 kV netwerk die vraag niet kan absorberen. Uitbreiding van het hoogspanningsnet gaat meerdere jaren duren. Gedurende deze periode kan er sprake zijn congestie.

Als er sprake is van (mogelijke) structurele congestie in de netten maken de netbeheerders daarvan per congestiegebied melding aan de Autoriteit Consument en Markt (ACM) en publiceren dit op de website. Voor het gebied rondom het station Oosterwolde heeft TenneT TSO B.V. op 23 december 2019 een vooraankondiging van mogelijke congestie gepubliceerd en de uitvoering van een onderzoek naar de toepassing van congestiemanagement aangekondigd.

Wat is de uitkomst van het onderzoek naar congestiemanagement?

TenneT TSO B.V.  heeft onderzoek gedaan naar de haalbaarheid van congestiemanagement voor 110 kV net rondom het onderstation Oosterwolde in Friesland. Dat onderzoek is uitgevoerd op basis van de Netcode Elektriciteit artikel 9.5 lid 5.

De volgende criteria spelen een belangrijke rol in het onderzoek:

  • congestiemanagement is volgens de netbeheerder nettechnisch mogelijk;
  • congestiemanagement is volgens de netbeheerder bedrijfsvoeringstechnisch mogelijk;
  • de periode van structurele congestie duurt langer dan 1 jaar en korter dan 4 jaar;
  • in het gebied zijn genoeg potentiële deelnemers voor de uitvoering van congestiemanagement.

De uitkomst van het onderzoek is dat congestiemanagement hier niet mogelijk is, omdat er niet kan worden voldaan aan alle criteria van de Netcode Elektriciteit. Er zijn niet voldoende potentiële deelnemers, er is niet voldoende volume voor congestiemanagement en er zijn onvoldoende monitoring- en sturingsmogelijkheden.

Nu het onderzoek afgerond is, vervalt ook de vooraankondiging van congestie voor dit gebied. Het totaal aan verwacht gecontracteerd vermogen is op dit moment 107 MW. Het totaal beschikbaar gestelde vermogen is 77 MW. Dat betekent dat er structurele congestie is totdat er maatregelen zijn genomen waarmee aanvullende transportcapaciteit kan worden gecreëerd.

news-2048 Thu, 13 Feb 2020 09:30:00 +0100 TenneT develops first 2GW offshore grid connection with suppliers https://www.tennet.eu/news/detail/tennet-develops-first-2gw-offshore-grid-connection-with-suppliers/ Forty percent of the Netherlands’ electricity needs will come from offshore wind farms by 2030. TenneT will realise the grid connections for these wind farms. Alongside the eight 0.7 Gigawatts (GW) AC grid connections already planned, two 2 GW offshore grid connections will be built in the IJmuiden Ver wind energy area. Such a grid connection is currently not existing. This requires a new platform design and a high voltage direct current (HVDC) transmission system that allows increased power transfer. Forty percent of the Netherlands’ electricity needs will come from offshore wind farms by 2030. TenneT will realise the grid connections for these wind farms. Alongside the eight 0.7 Gigawatts (GW) AC grid connections already planned, two 2 GW offshore grid connections will be built in the IJmuiden Ver wind energy area. Such a grid connection is currently not existing. This requires a new platform design and a high voltage direct current (HVDC) transmission system that allows increased power transfer.

TenneT has entered into a so-called innovation partnership* with its suppliers to ensure that this technically advanced and innovative requirement will connect seamlessly with what they can develop and manufacture.

Given the combination of the large distance to the coast and the size of the IJmuiden Ver wind energy area, a 2 GW direct current (HVDC) solution, based on 525 kilovolts, appears to offer most economical  advantages. It requires only one cable system per 2 GW, limiting the impact on the environment and the surroundings.

To realise such an innovative direct current system, TenneT launched the design phase with five HVDC suppliers on the basis of an innovation partnership: ABB Power Grids, GE Renewable Energy’s Grid Solutions  (Netherlands), Consortium Global Energy Interconnection Research Institute Co. Ltd. (GEIRI) & C-EPRI Electric Power Engineering Co. Ltd. (C-EPRI) (China), Siemens (Germany), and Xian Electric Engineering Co., Ltd (China). These suppliers will develop this innovative 2 GW 525 kV HVDC solution based on criteria set by TenneT. They will provide specific information on this to Iv-Offshore&Energy b.v., which is carrying out the Front-End Engineering Design (FEED) study on behalf of TenneT. On this basis, a standardised platform design will be developed for all HVDC solutions.

Standardised platform

The information from the joint R&D innovation phase will be used for the final design of the platform. TenneT uses this standardised design for the contracting of several 2 GW grid connections (including IJmuiden Ver Alpha and Beta). This contributes to reducing costs for the offshore grid.

TenneT thus fulfils its responsibility as grid operator of the offshore grid, by stimulating innovative solutions that contribute to rolling out a cost-efficient and future-proof offshore grid infrastructure.

Experience in Germany

The move to connections with a 2 GW capacity is made possible through TenneT’s extensive experience with offshore HVDC grid connections in Germany, as well as with interconnectors. TenneT also uses the high-voltage 525 kV level for the new international offshore connection between Germany and Norway, NordLink. TenneT will realise at least four 2 GW offshore grid connection projects in Germany from 2029. The results of the FEED study and the R&D phase of the innovation partnership will also provide emphatic input for this, because TenneT strives to standardise the systems wherever possible.

Scale of IJmuiden Ver-projects

IJmuiden Ver will have wind farms with a total capacity of 4 GW. With the new 2 GW connection concept, TenneT wants to make optimal use of the area’s scale. This is in line with the offshore wind industry’s desire for larger wind farms. TenneT is building two grid connections, each of 2 GW, for this purpose: Net op zee IJmuiden Ver Alpha, and Net op zee IJmuiden Beta. Preparations and procedures for these projects began in 2019, and Net op Zee IJmuiden Ver Alpha and Net op Zee IJmuiden Ver Beta are scheduled to go into operation prior to 2030.

*An innovation partnership is a tendering procedure in which TenneT, as contracting authority, can start a development process together with suppliers and then proceed to purchase the solution that is not yet available on the market.

Het nu bereikte onderhandelaarsakkoord voor de Noordzee is belangrijk voor een breed gedragen voortgang van de energietransitie in Nederland. TenneT ziet de Noordzee als een belangrijke bron van duurzame energie en realiseert zich tegelijkertijd dat dit gebied ook van groot belang is voor de natuur en voor andere sectoren waaronder scheepvaart, visserij en olie & gas.

Samen met deze partijen heeft TenneT zich in het afgelopen jaar ingezet om te komen tot overeenstemming waarbij nadrukkelijk rekening wordt gehouden met elkaars belangen. Zo zullen er onder andere aanvullende natuurgebieden worden aangewezen voor een gezond herstel van waardevolle natuur op de Noordzee. In die natuurgebieden zullen in principe geen windparken worden gebouwd. Maar er zal bijvoorbeeld ook gezocht worden naar gebieden voor extra windparken op zee (20-40 gigawatt) in gebieden die vanuit visserij als minder waardevol worden gezien.

Marco Kuijpers, directeur Large Projects Offshore bij TenneT: "Voor ons als netbeheerder van het net op zee – en daarmee verantwoordelijk voor het aansluiten van windparken en het transport van de duurzame elektriciteit naar land – is het belangrijk in een zo vroeg mogelijk stadium te weten waar de nieuwe windparken ontwikkeld kunnen gaan worden. Op die manier kan TenneT het net op zee in samenhang met het net op land in goed overleg met de vele stakeholders en daarmee tijdig realiseren."

TenneT dankt alle deelnemende partijen voor hun stevige, maar constructieve bijdrage aan de totstandkoming van dit onderhandelaars-akkoord voor een duurzame benutting van onze Noordzee en kijkt uit naar toekomstige samenwerking in het vervolg van het Noordzeeoverleg.

news-2026 Wed, 22 Jan 2020 08:20:53 +0100 Gasunie and TenneT: Climate goals can only be achieved with an integrated European energy system https://www.tennet.eu/news/detail/gasunie-and-tennet-climate-goals-can-only-be-achieved-with-an-integrated-european-energy-system/ Joint study of TenneT and Gasunie shows possible transition pathways towards an integrated European energy system with coupling of electricity and gas grids Expansion of the infrastructure for electricity transmission even after 2030 necessaryGas infrastructure must be adapted for hydrogen transportPower-to-Gas for long-term storage and transport of renewable energies
  • Joint study of TenneT and Gasunie shows possible transition pathways towards an integrated European energy system with coupling of electricity and gas grids
  • Expansion of the infrastructure for electricity transmission even after 2030 necessary
  • Gas infrastructure must be adapted for hydrogen transport
  • Power-to-Gas for long-term storage and transport of renewable energies
  • In order to successfully promote the energy transition and achieve climate targets, electricity and gas grids must be more closely interlinked by 2050. What the transition paths towards such an integrated energy system could look like shows the new study by transmission system operator TenneT and gas infrastructure company Gasunie. The study with a European approach concentrates on Germany and the Netherlands. The now published Phase II study follows on from the "Infrastructure Outlook 2050" published in February 2019 and shows that the electricity infrastructure will have to be significantly expanded even after 2030. The gas infrastructure must be adapted for the transport of hydrogen; a minor expansion is also necessary.

    According to the study it is important to plan the energy transmission infrastructures for electricity, hydrogen and methane in a timely and integrated manner. This helps to avoid stranded assets, which would ultimately lead to high costs for energy consumers. Here, the timing, amount, type and location of investment decisions in renewable energies (i.e. production), but especially in future (large) consumers (i.e. consumption), play an important role for an efficient energy infrastructure. Early and close coordination of energy production and consumption with the development of an integrated energy infrastructure is essential, if the latter is to be built in time. To provide the necessary long-term storage capacity, power-to-gas will play an important role. The study estimates a capacity of up to 110 gigawatts in Germany and the Netherlands.

    Another result of the study is the potential of the European approach to energy infrastructure integration. TenneT CEO Manon van Beek: “We need to integrate the gas and electricity grids to achieve the energy policy objectives. To do this we need an integrated European energy system. National energy transitions are important and will bring the first significant steps towards the expansion of renewables. But if we want the energy transition to be timely and affordable, we will need a close political cooperation within Europe.”

    Han Fennema, CEO Gasunie: “The existing gas and electricity networks jointly play a crucial role in the energy system of the future. In order to cope with increasing fluctuations in the energy network we need our gas and electricity infrastructures to be seamlessly aligned. Linking TenneT's network to Gasunie's will provide the flexibility required by the energy system; it will also keep the system reliable and affordable.”

    The Phase II study:

    “Phase II” is a joint study by TenneT and Gasunie that looks at possible transition paths from 2030 to an integrated energy system in 2050. It thus continues the investigations of the study "Infrastructure Outlook 2050" published last year by the two network operators. "Phase II" focuses on Germany and the Netherlands, but also highlights Europe. The study considers three different scenarios based on the findings of various studies: While all scenarios assume that decarbonisation will be largely achieved, they differ in terms of the type and quantity of renewable energies and in terms of energy consumption (Focus on either electricity or gas).

    news-2017 Fri, 17 Jan 2020 15:55:00 +0100 European cooperation vital for security of supply ater 2025 https://www.tennet.eu/news/detail/european-cooperation-vital-for-security-of-supply-ater-2025/ TenneT regards Northwest European cooperation on security of electricity supply as a vital condition for addressing uncertainty after 2025. On behalf of the Dutch Ministry of Economic Affairs and Climate, TenneT monitors annually whether the Netherlands has sufficient production capacity available to meet national electricity demand. The latest monitoring report shows that, up to 2025, security of supply is within the reliability standard. After 2025, the Netherlands will be reliant on electricity imports. To maintain security of supply levels, the Netherlands must discuss and agree a policy about available production capacity for electricity with neighbouring countries. TenneT regards Northwest European cooperation on security of electricity supply as a vital condition for addressing uncertainty after 2025. On behalf of the Dutch Ministry of Economic Affairs and Climate, TenneT monitors annually whether the Netherlands has sufficient production capacity available to meet national electricity demand. The latest monitoring report shows that, up to 2025, security of supply is within the reliability standard. After 2025, the Netherlands will be reliant on electricity imports. To maintain security of supply levels, the Netherlands must discuss and agree a policy about available production capacity for electricity with neighbouring countries.

    Following the publication of this annual Security of Supply Monitoring Report 2019 (2018-2034), Ben Voorhorst, COO of TenneT, says: ‘Like all our neighbouring countries, the Netherlands has its own policy and there is very little harmonisation of the various policies. This does not present a big problem for the coming years. However, to maintain mutual security of supply at a reliable level after 2025, we must start regulating this now for a larger area. It is therefore important to move security of supply higher up on the agenda. The energy transition and electrification of our society demand a European approach and cooperation to ensure a constant supply of electricity for everyone who needs it.’

    Increasing importance of flexibility

    Flexibilisation of the demand for electricity is a decisive factor for the success of the energy transition. Better alignment of demand and supply would mean fewer electricity imports. TenneT is therefore investigating the current situation in the TenneT Flexibility Monitor. Initial findings show that 700 MW of power, which is equivalent to around 100 large wind turbines, is being used in the Netherlands electricity market in the form of storage and flexible demand.

    Regional PLEF model

    Distribution network operators, relevant ministries and supervisors from seven countries (Benelux, Germany, France, Austria and Switzerland) are united in the PLEF (Pentalateral Energy Forum). Besides providing a platform for ongoing joint studies, this is an appropriate forum for discussing the policies of the countries involved and their impact on the Northwest European region.

    Conclusions of the monitoring report

    • Security of supply in the Netherlands is within the reliability standard until 2025. Within this period, there is sufficient production capacity in the Netherlands to meet national electricity demand. Thanks to TenneT’s transport connections with foreign countries, it is not expected that the standard of 4 hours per year (shortage of electricity supply compared to demand) will be exceeded, even in extreme scenarios.
    • After 2025 up to and including 2030, the number of gas-fired power stations in the Netherlands will decrease and the use of coal for electricity generation will be banned. This will increase dependence on foreign countries for security of supply. Based on current data, sufficient electricity generation capacity is available for export to the Netherlands. Consequently, average shortage will not exceed the standard of 4 hours, even in 2030. Only in extreme conditions the standard will be exceeded.
    • There is still no certainty about the energy landscape in 2030 and beyond. The energy supply is largely subject to government policy, both in the Netherlands and abroad. Furthermore, it is still unclear how electricity producers and customers will respond to a change of policy and electricity consumption.

    news-2014 Mon, 13 Jan 2020 10:12:18 +0100 TenneT increases offshore wind energy connection capacity to 7,132 megawatts https://www.tennet.eu/news/detail/tennet-increases-offshore-wind-energy-connection-capacity-to-7132-megawatts/ Expansion target of the federal government for 2020 already more than achieved The transmission capacity will increase to almost 10,000 megawatts by 2025 The 2019 North Sea “wind harvest” exceeds previous year by around 21 %
  • Expansion target of the federal government for 2020 already more than achieved
  • The transmission capacity will increase to almost 10,000 megawatts by 2025
  • The 2019 North Sea “wind harvest” exceeds previous year by around 21 %
  • In 2019, the transmission system operator TenneT has already met and even significantly exceeded the German government’s 2020 expansion targets for sustainable North Sea wind power. The federal government’s target for the North Sea and Baltic Sea for 2020 is a total of 6.5 gigawatts. TenneT's current total of twelve operating offshore grid connection systems for the transmission of wind energy from the German North Sea to land alone now deliver a total capacity of 7,132 megawatts.

    "We are pleased that we have already achieved the goal set by the federal government ahead of schedule," said TenneT Managing Director Tim Meyerjürgens, "and with the three other offshore grid connections currently being implemented, we will be capable of delivering 10,000 megawatts of transmission capacity from the North Sea in 2025 in Germany alone. We are pushing ahead with grid expansion on land just as rigorously, because this holistic approach is the key to a successful energy transition.”

    The wind energy transmitted from the North Sea by TenneT reached a new record in 2019 at 20.21 terawatt hours (TWh)*). This would be enough, for example, to cover the annual consumption of more than six million households. The 2019 result exceeded the previous year's value (16.75 TWh) by 20.7 percent. Measured against Germany’s total wind output (122.07 TWh, offshore and onshore counted together)*), the North Sea wind power yield achieved a healthy share of 16.6 percent in 2019. 

    "We also successfully put our first offshore grid connection into operation in the Netherlands in 2019. By 2023 we will develop the connected load there to 3,500 megawatts. In addition, we are advancing our 'green projects' and innovations in order to achieve the climate targets we are aiming for in Germany and Europe,” said Meyerjürgens, giving two examples: From the end of 2020, NordLink will for the first time connect the electricity markets of Germany and Norway directly with one another and link German wind energy with Norwegian hydropower in a mutual exchange. Together with partners in the automotive industry, TenneT is currently looking at promising test runs to store and exchange electricity between electric cars and the grid.
    Another key question that concerns TenneT: How may it be possible to cover Central Europe’s electricity demand using clean wind energy alone? TenneT has developed the idea of the North Sea Wind Power Hubs, which will open up to 180 gigawatts of offshore wind energy by 2045 and simultaneously better interconnect the grids of the countries bordering on the North Sea. “Together with our European partners, we are pursuing a modular, step-by-step approach, which will later include a combination with power-to-gas systems. This is not science fiction: A first hub with a capacity of 10 to 15 gigawatts could go into operation in the early 2030s,” says Meyerjürgens.

    Additional offshore balance data
    The previous maximum infeed performance of North Sea offshore wind farms reached 6,077 MW on 5 December 2019. The capacity expansion for North Sea offshore wind farms was at 6,436 MW on 31 December 2019.

    The wind turbines in the Baltic Sea (not within the TenneT grid area) generated 3.95 terawatt hours in 2019, which means Germany’s total offshore yield amounted to 24.16 terawatt hours. With an additional 97.91 terawatt hours of generated onshore wind energy, the total yield is thus 122.07 terawatt hours.*)

    *) Financially subsidised electricity in accordance with the German Renewable Energy Sources Act (EEG), without other direct marketing; for 2019, as the preliminary actual value. The volumes of energy produced onshore and in the Baltic Sea for the months of November and December 2019 are incorporated as preliminary estimated values.

    news-2012 Mon, 13 Jan 2020 08:00:00 +0100 Ocean Renewable Energy Action Coalition Launches to Accelerate Global Offshore Wind Capacity https://www.tennet.eu/news/detail/ocean-renewable-energy-action-coalition-launches-to-accelerate-global-offshore-wind-capacity/ An international Ocean Renewable Energy Action Coalition has been formed to advance sustainable deployment of ocean-based renewable energy and mitigate the harmful impacts of climate change. An international Ocean Renewable Energy Action Coalition has been formed to advance sustainable deployment of ocean-based renewable energy and mitigate the harmful impacts of climate change.

    Ocean-based renewable energy—such as offshore wind, floating solar, tidal and wave power—could meet nearly 10% of the annual greenhouse gas emissions reductions needed by 2050 to keep global temperatures under 1.5ºC above pre-industrial levels, according to a report released by the High-Level Panel for a Sustainable Ocean Economy. Most of this climate change mitigation potential is expected to come from offshore wind.

    Bringing together civil society, intergovernmental institutions and industry, the Action Coalition will represent the offshore wind sector in the global dialogue on climate action. It will be spearheaded by Ørsted and Equinor. The group also includes: CWind, Global Marine Group, JERA, MHI Vestas, Mainstream Renewable Power, Shell, Siemens Gamesa, TenneT and The Crown Estate.

    The Action Coalition was formed in response to the September 2019 Call for Ocean-Based Climate Action made by the High-Level Panel for a Sustainable Ocean Economy, with additional partners including Global Wind Energy Council and the UN Global Compact. 

    The Action Coalition will prepare a vision for 2050, highlighting the actions that industry, financiers and governments can take to sustainably scale-up offshore wind, and thereby contribute to the UN Sustainable Development Goals and global decarbonization goals. Initial outputs will be announced at the UN Ocean Conference in Lisbon in June 2020.

    “If we’re serious about fighting the climate crisis, it’s vital we decarbonise the world’s energy use as quickly as possible through technologies like offshore wind. The Ocean Renewable Energy Action Coalition will work together to accelerate the opportunity presented by ocean renewables to achieve the Paris Agreement goals,” says Benj Sykes, Vice President at Ørsted.

    “Collaboration between nations and companies is needed to accelerate the sustainable deployment of ocean renewable energy. This Action Coalition includes leading industry players in offshore wind and we are working together to unleash the full potential of offshore wind globally,” says Stephen Bull, Senior Vice President for Wind and Low Carbon at Equinor. 

    Driven by a small number of countries initially, offshore wind is now on a spectacular cost reduction path. It is capable of producing clean energy at tremendous scale and will be a key technology to enable the energy transition and to support a sustainable future.

    news-1999 Wed, 11 Dec 2019 11:37:10 +0100 “MIGRATE” research project takes stock after four years https://www.tennet.eu/news/detail/migrate-research-project-takes-stock-after-four-years/ The focus: Integrating renewables into a stable, future-proof transmission system gridDifferent approaches for the power grid of the future
  • The focus: Integrating renewables into a stable, future-proof transmission system grid
  • Different approaches for the power grid of the future
  • “MIGRATE” – 25 consortium partners from 13 countries, transmission system operators, universities and research institutes worked together under this acronym for four years on the future of the European power grid. In January 2016, the European research project “Massive Integration of Power Electronic Devices”, MIGRATE for short, was launched. The project, which was coordinated throughout Europe by TenneT, was funded by the EU to the tune of around 17 million euros. The final conference has now been held in Brussels.

    Some of the problems addressed by “MIGRATE” were: What does the increasingly decentralised infeed mean for grid stability and how can the European power grid be operated with 100 percent renewable energies? Five technical work packages investigated the effects of these changes and developing recommendations for future grid connection rules.

    Increasing electricity production using renewable energies and the shutdown of conventional large power stations have a major impact on the operation of electrical grids. Wind turbines and photovoltaic systems typically feed the electricity into the grid through power electronic converters, while classic power stations use large rotating generators. The main difference between these two technologies is how they are controlled, e.g. their voltage, power and frequency on the electric grid.

    For this reason, the power grid of the future not only has to be flexible to securely transport the decentrally generated power to the electrical load. Planning and operation also have to consider the changing properties of the generators themselves. Against this backdrop, it is necessary to develop new technologies to be able to reliably operate a future grid with 100 percent renewable energies – and thus 100 percent power electronics.

    One essential point is adapting control strategies to generation operation. This adjustment alone can enable reliable operation of the electric grid with power electronics up to 65 percent. To cover the remaining 35 percent in stable grid operations, new, innovative solutions were developed as part of the MIGRATE research project.

    Grid monitoring plays a major role. To keep this requirement possible in real-time, MIGRATE successfully tested a new WAMPAC system (wide area monitoring protection and control). This process allows the grid operator plant management staff to quickly and reliably detect whether and when the limits of reliable grid operations are reached.

    The data from connected wind farms or photovoltaic systems are not required – instead, the measurements of the electric grid alone are used. This makes the process much more robust against information transmission malfunctions.

    Ideally, the grid voltage should vibrate at 50 Hertz.  A phenomenon more often being seen in electricity grids are vibrations with frequencies above 50 Hertz. These vibrations must be avoided. They not only cause additional losses in the system, but can also interfere with the function of, or even destroy connected devices.

    MIGRATE has advanced the methods for assessing these phenomena and reducing these harmonics.

    Another important function for reliable grid operations: protection systems that disconnect the affected equipment from the grid in case of a fault, such as a short circuit. In households, this function is assumed by fuses. MIGRATE also investigated possible safety system failure due to changed future grid properties, defining countermeasures.

    Some of the working results are already being utilised by transmission system operators. It was also important for the MIGRATE project to gain new insights into how the European transmission system grid of the future will change in conjunction with future generation plants. MIGRATE therefore also represented a good start in the cooperation between European transmission system operators with system manufacturers in this field.

    On the project website www.h2020-migrate.eu, a short film presents both the objective and the key MIGRATE project results.

Significant increases in traded volumes reported across the 7 countries which joined the SIDC coupling last week. Pan-European trading now in place across 21 countries coupled through SIDC. System performing well.

    Nominated Electricity Market Operators (NEMOs) and Transmission System Operators (TSOs) confirm the successful go-live of the second launch of SIDC (formerly known as XBID). In the first two hours after cross-border trading opened on 19th November, OTE, the Czech NEMO, reported that more than 1 000 trades were completed for delivery on 20th November. The Croatian NEMO, CROPEX, recorded trades with market participants in 16 different countries including Norway and Spain. HUPX, the Hungarian NEMO, reported an increase in traded volumes of nearly 14 times in the five days following go-live, compared to the five prior to the launch. In Bulgaria, IBEX states that the average number of trades has doubled since the go-live and OPCOM, the Romanian NEMO, also reports a near doubling of both traded volumes and number of trades. In Slovenia, BSP Southpool has stated that for the period after go-live, compared to the equivalent period in 2018, it has seen an eight-fold increase in traded volume (11 672 MWh compared to 1 425 MWh). Meanwhile in Poland, TGE has achieved a daily average of over 2 000 MWh since go-live, which is a more than nine-fold increase when compared to the 2018 intraday daily average of 212 MWh.

    Marking another important step towards expanding the single integrated European Intraday market, the successful SIDC go-live expanded the continuous trading of electricity across the following countries: Bulgaria, Croatia, Czech Republic, Hungary, Poland, Romania and Slovenia. They joined the existing countries already operating the SIDC: Austria, Belgium, Denmark, Estonia, Finland, France, Germany, Latvia, Lithuania, Norway, The Netherlands, Portugal, Spain and Sweden. A 3rd wave go-live is expected by the end of 2020.

    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.

    Investing in the energy transition

    TenneT is driving the European energy transition and expects to invest EUR 35 billion in offshore and onshore grid connections across the Netherlands and Germany over the next ten years. Approx. 80 percent of TenneT's investments are directly related to the energy transition and renewable electricity production, such as wind and solar energy. In the period up to 2030, TenneT expects to have realized approximately 25 gigawatts (GW) of connection capacity for offshore wind farms in the Dutch and German parts of the North Sea, transmitting electricity sufficient to power 31 million households for a full year.

  • Joint pilot project shows the potential of intelligent charging control for electric cars in supporting grid stability
  • Digital integration makes electromobility an important component of the energy transition
  • A joint pilot project of the transmission system operator TenneT and the BMW Group has now shown how the charging strategy for electric vehicles can be intelligently adapted to the capacity utilisation in the power grid and the availability of renewable energy. The pilot project could represent the basis for a realisation of this solution at a larger scale.

    The rise in renewable energy and electromobility poses a challenge to the security of supply: The key is to coordinate power generation and power consumption and, at the same time, ensure the stability of the power grid. “If we digitally integrate electric cars into the power grid, the charging processes can be coordinated with both the mobility needs of the drivers and the demands of grid stability. In this way, intelligent charging control can contribute to avoiding congestion in the power grid while giving the right of way to green energy,” says TenneT Managing Director Tim Meyerjürgens. “We are opening up new ways of flexibly controlling the highly weather-dependent renewable electricity production. This lowers the burden on the power grid, allowing intelligent charging control of electric cars to supplement grid expansion measures and become one of the components of the energy transition.”

    Within the framework of the pilot project, the BMW Group used intelligent charging control and interconnected electronics in the pilot vehicles to register and process signals from TenneT concerning the threat of grid overloads, temporarily interrupting the charging of selected BMW i3s. The freed-up power could be used by TenneT to balance out grid congestion, thereby avoiding the use of conventional fossil power stations.

    Nowadays, due to the increasing decentralised infeed of renewable energy sources, congestion is becoming ever more common in the power grid. To prevent such congestion, TenneT intervenes in the production of conventional power stations (redispatch) and renewables (wind power curtailment), thus ensuring that electricity transport remains within the transmission capacity of the grid. The associated costs across Germany in 2018 amounted to approximately 1.4 billion euros, of which about 500 million euros can be attributed to interventions in conventional production. These costs are ultimately borne by electricity consumers through grid charges. As the energy transition progresses, new types of flexibility such as electromobility should take on the duties of conventional power stations. TenneT is therefore using the pilot project with the BMW Group as well as other pilot projects to test which decentralised types of flexibility can be used in the future to stabilise the grid, in the interests of finding tomorrow’s solutions today.

    news-1979 Wed, 06 Nov 2019 16:58:08 +0100 EU-funded PROMOTioN project delivers recommendations to overcome regulatory and financial barriers to realizing a North Sea Transmission Grid https://www.tennet.eu/news/detail/eu-funded-promotion-project-delivers-recommendations-to-overcome-regulatory-and-financial-barriers-t/ Arnhem/Berlin, 6 November 2019. Countries around the North Sea need to implement a harmonized regulatory and economic framework to fully exploit the potential of a meshed offshore grid in the North Sea. This is a key conclusion of the EU-funded research project PROMOTioN (Progress on Offshore Meshed HVDC Transmission Networks). Tim Meyerjürgens, COO at TenneT, stresses: “The development of a cross-border HVDC grid is one of the most promising opportunities for a sustainable energy future in Europe. TenneT is cooperating closely with other TSOs to develop the idea of a meshed and efficient offshore grid in the North Sea, which requires the creation of a common regulatory framework. PROMOTioN's research shows the way to make this happen.” Similarly Ditlev Engel, CEO of DNV GL Energy, states: “The development of a reliable transnational European offshore transmission grid is a key enabler for a successful, cost effective and timely energy transition. This project delivered a great framework with regulatory and financial guidelines for national governments to speed up collaboration on the joint development of energy infrastructure such as offshore transmission grids. And that is really needed to accommodate the rise of renewables and meet our goals in the Paris Agreement.” PROMOTioN’s latest report, “D7.9 Regulatory and financing principles for a meshed HVDC offshore grid”, summarizes the key findings on the design of a legal, regulatory and financing framework for cross-border HVDC offshore connections and provides recommendations for policy makers and other stakeholders to take appropriate measures to enable the first hybrid assets to be built. Short-term recommendations In the short-term, it is recommended to improve the governance and the regulation of the internal market for (offshore) electricity by including in the Electricity Regulation a definition and substantive provisions on the regulation of a hybrid asset; assets which combine both interconnection and wind farm export functionalitiesprovide innovation funding for novel ideas and technologies (e.g. novel energy storage techniques), and fund anticipatory investment which is cost-effective in delivering a meshed offshore grid (e.g. island hubs)support early communication between developers, authorities and other key stakeholders about new wind farm projects to enable early identification of meshed offshore grid development needs.

Countries around the North Sea need to implement a harmonized regulatory and economic framework to fully exploit the potential of a meshed offshore grid in the North Sea. This is a key conclusion of the EU-funded research project PROMOTioN (Progress on Offshore Meshed HVDC Transmission Networks).

    Tim Meyerjürgens, COO at TenneT, stresses: “The development of a cross-border HVDC grid is one of the most promising opportunities for a sustainable energy future in Europe. TenneT is cooperating closely with other TSOs to develop the idea of a meshed and efficient offshore grid in the North Sea, which requires the creation of a common regulatory framework. PROMOTioN's research shows the way to make this happen.”

    Similarly Ditlev Engel, CEO of DNV GL Energy, states: “The development of a reliable transnational European offshore transmission grid is a key enabler for a successful, cost effective and timely energy transition. This project delivered a great framework with regulatory and financial guidelines for national governments to speed up collaboration on the joint development of energy infrastructure such as offshore transmission grids. And that is really needed to accommodate the rise of renewables and meet our goals in the Paris Agreement.”

    PROMOTioN’s latest report, “D7.9 Regulatory and financing principles for a meshed HVDC offshore grid”, summarizes the key findings on the design of a legal, regulatory and financing framework for cross-border HVDC offshore connections and provides recommendations for policy makers and other stakeholders to take appropriate measures to enable the first hybrid assets to be built.

    Short-term recommendations

    In the short-term, it is recommended to

    • improve the governance and the regulation of the internal market for (offshore) electricity by including in the Electricity Regulation a definition and substantive provisions on the regulation of a hybrid asset; assets which combine both interconnection and wind farm export functionalities

    • provide innovation funding for novel ideas and technologies (e.g. novel energy storage techniques), and fund anticipatory investment which is cost-effective in delivering a meshed offshore grid (e.g. island hubs)

    • support early communication between developers, authorities and other key stakeholders about new wind farm projects to enable early identification of meshed offshore grid development needs. Opportunities for wider stakeholder involvement in the decision making process should also be identified

    • formalize of the Cross-Border Cost Allocation (CBCA) as a binding contract between the involved parties with a clear specification of non-compliance penalties. CBCA coordination is one of the most important pillars in the economic framework and should be promoted for complementary projects.

    Long-term regulatory stability

    To provide long-term regulatory stability, PROMOTioN recommends Member-States, third countries and the EU to consider the adoption a North Sea treaty, containing the aims and principles of the offshore grid.  This treaty would provide a stable governance and decision-making structure, a common interpretation of maritime law, and processes for long-term wind farm and grid planning (geographical and temporal, in a similar way as the Ten-Year Network Development Plan process). Moreover, it would allow for formal operational regulatory governance, fixing the terms of cooperation between National Regulatory Authorities and their decision-making process regarding cross-border links.

    Financing the infrastructure

    The long-term legal and regulatory stability is especially important for financing the offshore grid. Investors rely on stable and predictable conditions which includes an assignment of clear roles and responsibilities among the relevant actors. Moreover, equity provision for the required offshore grid investment volumes needs to be facilitated. This can be realized in several ways that are presented in the report. Additionally, it is essential that transmission owners’ income is not based on congestion rents, but is regulated with a long-term predictable revenue stream which creates certainty to investors and thus, attracts investments in offshore grid assets.

    news-1964 Mon, 14 Oct 2019 11:14:12 +0200 TenneT officially commissions Randstad 380 kV North Ring https://www.tennet.eu/news/detail/tennet-officially-commissions-randstad-380-kv-north-ring/ After five years of construction, the 60-kilometre-long Randstad 380 kV North Ring connection has been commissioned. This new 380 kV high-voltage power transmission line will deliver a reliable electricity supply to millions of households and companies in the Randstad region. Moreover, this power artery will provide the required transmission capacity for green electricity produced by North Sea wind farms. After five years of construction, the 60-kilometre-long Randstad 380 kV North Ring connection has been commissioned. This new 380 kV high-voltage power transmission line will deliver a reliable electricity supply to millions of households and companies in the Randstad region. Moreover, this power artery will provide the required transmission capacity for green electricity produced by North Sea wind farms.

    Stretching 60 kilometres from Beverwijk to Bleiswijk, the new electricity connection is TenneT’s largest land-based project in the Netherlands and has been built in Europe’s most densely populated region. At the same time, the region’s existing 150 kV connections have been adapted and two new high voltage substations have been built in Beverwijk and Vijfhuizen.

    Innovation

    At 151 locations between Beverwijk and Bleiswijk, new Wintrack pylons have been erected. Their slender design and light grey colour scheme have shown to be ideally suited to the heavily populated Randstad region. Ten kilometres of the 60-kilometre-long 380 kV high-voltage interconnection that forms part of the meshed grid have been laid underground, which is a global first. The new aluminium cables that have been used are cheaper than traditional materials and they conduct electricity more efficiently, which means their carbon footprint is smaller.

    The facts

    Of the 151 Wintrack pylons, 24 are ‘only’ 43 metres tall and are located near Schiphol. An 80-metre-tall Wintrack pylon guarantees shipping a safe passage along the Ringvaart Canal at Rijpwetering. On average, each Wintrack pylon, the heaviest of which weighs in at 70 tonnes, stands on 25 piles that have each been driven 20-30 metres into the ground. The depth of the underground cables ranges from 34 metres in the North Sea Canal to 1.80 metres in a trench. The Randstad North Ring crosses six motorways, seven waterways and three railways. 

    Teamwork

    More than 1000 people from the region, 300 landowners, over 25 competent authorities, 13 building contractors and 200 TenneT employees were involved in the construction.

    Local cooperation

    During the morning of 10 October, the finishing touches were put to the work at Kaag en Braassem. Here, TenneT and the local residents of the Ghoybos had jointly come up with a sustainable initiative: the landscaping of the fencing around the transition compound in the heart of the Ghoybos, aimed at improving the visual impact of the high voltage connection in the area; Botersloot architectural design bureau had developed two alternative schemes for TenneT, after which the residents and businesses voted virtually unanimously for the ‘floral’ option. TenneT CEO Manon van Beek: ‘This project shows just how important TenneT's role in the community is. We have both the responsibility and the ambition to play a key role in the energy transition, in which sustainability, security of supply and affordability are paramount.’

    news-1963 Thu, 10 Oct 2019 11:20:57 +0200 TenneT to invest an additional €215 mio in high voltage grid in the north of the Netherlands https://www.tennet.eu/news/detail/tennet-to-invest-an-additional-EUR215-mio-in-high-voltage-grid-in-the-north-of-the-netherlands/ TenneT is planning to invest an additional €215 million in connection capacity for two GigaWatts (GW) of solar and wind farms in the north of Netherlands. Two new 380 kV/110 kV high voltage substations will be constructed in the provinces of Groningen and Drenthe. These projects are expected to be completed around 2025, depending on any procedures. TenneT is planning to invest an additional €215 million in connection capacity for two GigaWatts (GW) of solar and wind farms in the north of Netherlands. Two new 380 kV/110 kV high voltage substations will be constructed in the provinces of Groningen and Drenthe. These projects are expected to be completed around 2025, depending on any procedures.

    In addition, TenneT wants to realise extra capacity at the existing 110 kV high voltage substations in Bargermeer, Coevorden, Emmen Weerdinge, Hardenberg, Klazienaveen, Musselkanaal Zandberg, Ommen Dante, Stadskanaal and Veenoord.

    One gigawatt corresponds to the capacity of around 3.5 million solar panels or around 200 wind turbines. Ben Voorhorst, COO at TenneT: ‘We want to honour as many transmission requests as possible for solar parks and wind farms. In view of the requests for connecting renewable projects, we will also look closely at where our sustainable investments are most needed and most efficient. The better capacity expansions of electricity grids are fully utilised, the better consumers’ money will be spent. In total we now have projects in the north worth more than 1 billion euros. This 215 million euros will come on top of that.’

    Temporary measures

    Voorhorst: ‘We are looking at all possible ways to find and realise more capacity in the grid.’  Being allowed to connect solar parks without a backup is one of these. Then the available reserve in the 110kV grid will be used for connecting additional sustainable generation. The regulator (ACM) will, however, have to grant an exemption for this, because the use of the 'reserve strip' is currently not permitted.

    If this exemption is granted, 500 megawatts of additional connection and transmission capacity will become available immediately. TenneT can distribute this to high voltage substations in the vicinity of solar parks, which means a large number of extra initiatives for sustainable generation can be added next year. TenneT will submit an exemption request to the ACM this month.

    Curtailment is another way to create more capacity on the grid. This means that only if the supply of sustainable electricity exceeds demand solar parks will be temporarily shut down. More parks can be built with the application of curtailment.

    Whether or not connecting solar parks without a backup connection and curtailment will be temporary measures has not yet been decided. The fact is that scarcity on the grid will remain in the short term. After all, TenneT does not have a complete overview of all requests to connect to the grid. In addition, TenneT has to follow procedures, make planning preparations, apply for permits, and deal with construction times and scarcity on the labour market.

    The planning preparations and permit applications for constructing new infrastructure like a large high voltage substation take between 4 and 10 years. Construction itself will last about 2 years.

    These are some of the projects that TenneT is implementing or planning in the north of the Netherlands.

    Projects in progress

    • Reinforcement of the 110 kV grid at Eemshaven with, among other things, the construction of a new 110 kV high voltage substation in Eemshaven. To be completed in early 2020.
    • Expanding and adapting high voltage substations for the transmission of sustainable energy: such as Delfzijl Weiwerd 110 kV and Meeden (110/220 kV with an additional 380 kV for interconnection with Germany). The substations will have new transformers and fields for more power. To be completed in late 2020.
    • Reinforcing the grid in Friesland with a new high voltage substation (at Bolsward), needed to connect the Fryslan wind farm and other sustainable initiatives. Construction starting at Bolsward of a 30-km-long underground cable connection in the verge of the A7 to Heerenveen. The connection will be ready in late 2020, the substation a year later.
    • Modifications to the Kropswolde high voltage substation for the connection of the 100 MW solar park at Kolham. To be completed in late October 2019.

    Planned projects

    • The construction of the electricity highway (380 kV connection) from Eemshaven to the Vierverlaten high voltage substation (Hoogkerk near Groningen) is important. Part of this project is the expansion of the Vierverlaten high voltage substation, which will be the largest in the Netherlands after commissioning. TenneT hopes to be able to start construction in 2020. The 380 kV connection is expected to be completed in 2023.
    • Expansion of transmission capacity of several connections. Better (new) electricity conductors will replace the current ones and so TenneT is strengthening some pylons. Such as the connection from Delfzijl to Groningen (Hunze) that will be worked on from next year.
    • With the construction of a large wind farm north of the Wadden Islands, 700 MW of sustainable electricity will be added to the high voltage grid (2026). How the wind farm is connected (and to which location) is still under investigation; together with the stakeholder relations, TenneT is looking for (underground cable) alternatives. This week and the coming week the Ministry of Economic Affairs is organising walk-in meetings about the plans.

    news-1960 Thu, 10 Oct 2019 10:30:00 +0200 Port of Rotterdam’s power grid can be reinforced more efficiently and at a lower cost https://www.tennet.eu/news/detail/port-of-rotterdams-power-grid-can-be-reinforced-more-efficiently-and-at-a-lower-cost/ Over the next few decades, there will be a substantial increase in the demand for green and other electric power on the part of Rotterdam’s industrial sector. The companies will need this extra power for the electrification of industrial processes, the production of green hydrogen and for electric transport. The demand for electricity is expected to increase by a factor of two – and possibly even four. This means that Rotterdam is required to reinforce its power grid. However, there is only limited space for extra infrastructure. Moreover, reinforcing the grid will lead to lower costs to society and shorter lead times when this is done based on a long-term vision instead of existing legislation and regulations. These are the findings of a study performed by the Port of Rotterdam Authority, Stedin and TenneT into the consequences of the energy transition for the power grid in Rotterdam’s port area. Over the next few decades, there will be a substantial increase in the demand for green and other electric power on the part of Rotterdam’s industrial sector. The companies will need this extra power for the electrification of industrial processes, the production of green hydrogen and for electric transport. The demand for electricity is expected to increase by a factor of two – and possibly even four. This means that Rotterdam is required to reinforce its power grid. However, there is only limited space for extra infrastructure. Moreover, reinforcing the grid will lead to lower costs to society and shorter lead times when this is done based on a long-term vision instead of existing legislation and regulations. These are the findings of a study performed by the Port of Rotterdam Authority, Stedin and TenneT into the consequences of the energy transition for the power grid in Rotterdam’s port area.

    The joint study concludes that this issue is particularly urgent because the capacity of the existing power grids and connections in the port of Rotterdam does not suffice to accommodate future plans for a sustainable port area. The lead time for realising new high voltage substations and power lines can be anything from 3 to 10 years. The point of departure of the study was that in the decades ahead, the Netherlands’ energy transition will be in line with the Paris Agreement on Climate Change, with renewable electric power and green hydrogen playing key roles in this process.

    Recommendations

    The study includes three recommendation to ensure that the necessary reinforcement of the network is completed in due time and at the lowest possible cost to society. The first recommendation concerns the adaptation of legislation and regulations, to enable the step-by-step realisation of infrastructure based on a long-term vision (for 2050) – rather than a piecemeal response to the requests of individual companies. This can result in lower costs for society (avoiding the unnecessary installation of parallel power cables), shorter lead times and can minimise physical bottlenecks. After all, there is only limited space available in the port area. In this process, the right balance has to be struck between the timely completion of infrastructure and the lowest possible risk of this capacity being temporarily or permanently underutilised.
    The second recommendation is that the Dutch Ministry of Economic Affairs and Climate Policy (or the participants in the ‘Klimaattafel Industrie’ roundtable) select locations directly along the coast for the large-scale conversion of electric power (generated using offshore wind) into hydrogen and other energy carriers. The underlying reasoning is that hydrogen transport requires far less space and lower investments than transporting electric power. Incidentally, the economic feasibility of large-scale hydrogen production is dependent on a substantial reduction in the costs of the process of electrolysis.
    The third recommendation is to already reserve space in the port for future electricity infrastructure, enabling the step-by-step realisation of a robust and future-proof power grid.

    Robust network

    To increase insight into the required adjustments to the power grid, the two grid operators and the Port Authority have explored a variety of technical alternatives. In this process, they have centred on the development of a robust network that can accommodate the growing demand for electric power at the lowest cost to society. The connecting theme in the plans to reinforce the grid is the increased transport at higher voltage levels (150 kV and higher) combined with smaller service regions at lower grid levels (66 kV and below). It is clear that this approach calls for a larger number of high voltage substations. This decision will limit the number of new underground power lines that need to be installed, which in turn reduces the claim to scarce space in the pipeline corridors (fewer physical bottlenecks).
    One promising alternative for the power grid is dividing the 150 kV network into a western, central and eastern section. Creating a larger number of substations within the distribution network will ultimately result in fewer power lines in the pipeline corridors and shorter connecting lines to the clients’ respective locations.

    First come, first served

    The most effective electric infrastructure for Rotterdam’s port area can not be realised without changing existing regulations. At present, new client applications for extra connection capacity are handled independently of each other and on a ‘first come, first served’ basis. This is a result of the principle laid down in current regulations that grid operators’ procedures need to be non-discriminatory. In many cases, the result is that new and existing clients are hooked up to the public grid via long connecting lines and are confronted with substantial connection costs.

    Careful coordination could limit the increase in the number of new electric connections – and, as a result, the total cost to society. Constructive collaboration between TenneT, Stedin and the Port of Rotterdam Authority will prove of vital importance in the decades ahead. After all, while the electric infrastructure is managed by two grid operators, it is in fact a single, coherent system. The Port Authority is responsible for managing the scarce space that accommodates this grid, and moreover has insight into the other infrastructure required for a successful energy transition.
