TenneT, National Grid Ink Joint Development Agreement For LionLink Offshore Wind Interconnector
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
Transmission system operators (TSOs) TenneT and National Grid Ventures (NGV) have signed a Joint Development Agreement (JDA) to advance LionLink, a hybrid interconnector linking the UK and the Netherlands via a future offshore wind farm in the Dutch North Sea.
These three paragraphs add more details.
The agreement sets out how the two partners will jointly develop LionLink towards a final investment decision (FID), including arrangements on procurement, governance, and planning, while also aiming to increase transparency on project costs ahead of construction.
LionLink is designed to integrate cross-border electricity interconnection with offshore wind by establishing a direct connection between the two countries through a grid link to the planned Nederwiek 3 offshore wind farm. According to the developers, this approach will maximise the use of offshore wind, provide additional system flexibility, and reduce the overall amount of required offshore infrastructure.
The LionLink project was launched in April 2023, when the Netherlands and the UK unveiled their plan to build the interconnector, a first-of-its-kind electricity link to connect offshore wind between the two countries via interconnections.
The same article also said these two paragraphs about the operation of the BritNed interconnector.
While the companies move forward with LionLink, their existing BritNed interconnector is marking 15 years of operation. Since entering service in 2011, the 1 GW subsea link has enabled nearly 93 TWh of electricity trading between Great Britain and the Netherlands.
Over the past five years, BritNed has exchanged enough electricity annually to power around 1.4 million households. The 260-kilometre interconnector remains a key part of both countries’ energy systems and has generated around EUR 1 billion in auction revenues on the Dutch side during its operational lifetime, TenneT said in a press release on 1 April.
It looks like BritNed has been a good investment for all stakeholders.
Note.
- LionLink will be a 2 GW interconnector.
- LionLink will land at Walberswick in Suffolk.
- LionLink has a web site.
- BritNed is a 1 GW interconnector.
- BritNed lands at the Isle of Grain in Kent.
- BritNed has a web site.
- NemoLink is an interconnector between Kent and Belgium.
- NeuConnect will be a 1.4 GW interconnector between the Isle of Grain and Wilhelmshaven, which will be operational by 2028.
- There are two actual and two proposed interconnectors between the UK and France.
The List of high-voltage transmission links in the United Kingdom in Wikipedia is growing.
The Wikipedia entry says this about the Rise of UK Interconnection.
The Department for Energy Security and Net Zero’s Digest of UK Energy Statistics reports that the UK was a net importer of electricity in 2024, with net imports of 33.4 TWh, up 40% from 2023.
Interconnectors allow the trade of electricity between countries with excess generation (for example, intermittent renewable) and those with high demand. Interconnectors play a key part in balancing variable renewable generation, for example the 1.4 GW North Sea Link allows the UK to export excess power to Norway during windy periods to conserve Norwegian hydro stocks, and import Norwegian hydro power on less windy days.
During the 2022 energy crisis, the UK exported record amounts of power to mainland Europe, helping to alleviate the effects of the Russian invasion of Ukraine on European security of supply.
As of 12 November 2024, Great Britain had nine operational international electricity interconnectors.
The UK is becoming an offshore energy substation on Europe’s North-West coast.
EU, France Grant EUR 126 Million For BW Ideol’s Floating Foundation Factory
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
BW Ideol has signed the final grant agreement for up to EUR 74 million from the EU Innovation Fund for a factory in Fos-sur-Mer, France, that will produce concrete floating wind foundations. The factory, dubbed Fos3F, has also secured up to EUR 52 million from the French State.
These three paragraphs add more detail.
The final agreement for the EU Innovation Fund grant was signed on 19 March, after BW Ideol revealed in November 2025 that the Fos3F was selected for up to EUR 74 million in funding by the European Commission.
The French government awarded support for the project at the end of 2025 through the C3IV tax credit scheme, dedicated to supporting leading French companies in the Green Industry. The funding from the French State will cover up to EUR 52 million to partially fund development and capital expenditures.
According to BW Ideol, if built, the Fos3F will be a first-of-its-kind factory dedicated to the serial production of concrete floating wind foundations based on the company’s patented Damping Pool.
The factory is stated to have a capacity of thirty foundations per year.
This Google Map shows the location of Fos-sur-Mer.
Note.
- Arles is in the North-West corner.
- Marseille is in the South-East corner.
- The mouth of the Rhône River is in between.
- Fos-sur-Mer is outlined by the red-and-white border.
Google AI says there is significant steel making at the mouth of the Rhône River.
I also asked Google AI, “What turbines will BW Ideol floating foundations support? and received this reply.
BW Ideol’s floating foundations are designed to be universal, supporting all major 15 MW+ offshore wind turbines currently on the market, with scalability to future 20 MW+ platforms. Their concrete barge-type technology—using the Damping Pool® design—is compatible with both existing and next-generation turbine manufacturers.
Key Compatibility Details:
15 MW+ and 20 MW+ Turbines: The foundations are engineered for current large-scale turbines (15 MW+) and are ready to accommodate upcoming 20 MW+ turbines, with designs already certified by DNV.
Proven Technology: The technology has been in operation since 2018 at the Floatgen site in France (using a Vestas V80 2 MW turbine) and in Japan, covering both shallow and deep-water applications.
Universal Application: The design is tailored for diverse metocean conditions and is designed to support the commercial deployment of large turbines in projects like the Buchan Offshore Wind project in Scotland.
Production Scalability: The concrete floating platforms are designed for mass production, capable of being manufactured quickly in a factory setting, such as the proposed Fos-sur-Mer site, to meet the schedules of major developers.
These foundations have received Design Certification from DNV, confirming their suitability for large-scale, commercial floating wind farms.
My Thoughts:
Concrete v. Steel: I used to work with someone, who was a big advocate of concrete yachts. Also check out the Wikipedia entry for the Troll A platform, which is a concrete Norwegian gas platform.
Zero-Carbon: I wouldn’t be surprised if concrete manufacture emits less carbon, than steel.
Port Talbot: Will BW Ideol build a similar factory at Port Talbot? I wrote about the Port Talbot factory in Port Talbot To Become Offshore Wind Hub For Celtic Sea. Both sites are next to a large bay, which would be ideal for parking completed floats and a world-class steelworks.
Buchan: Buchan’s web site says it will use seventy BW Ideol floats and generate I GW, 75 km. to the North-East of Fraserburgh. Google AI said the floats will be built at the Port of Ardersier.
Will A Mini-Steel Mill Be Built At The Port Of Ardersier?
I asked Google AI, the question in the title of this section and received this reply.
Yes, a £300 million green steel mill is planned for the Ardersier Port redevelopment as part of its transformation into a circular Energy Transition Facility. This facility aims to process scrap steel from decommissioned oil rigs into new materials to support offshore wind developments, alongside creating a concrete production plant.
Key details regarding the development:
Purpose: The mill is intended to process scrap from offshore decommissioning.
Technology: It is planned as a green steel plant.
Integration: It is aimed to be integrated into a new, fully circular “Energy Transition Facility”.
Context: While the facility aims for circular steel production, the port is primarily focused on becoming a hub for offshore wind and manufacturing.
Recent developments as of March 2026 suggest a focus on a “scaled back,” more achievable vision by new owners/managers, focusing on floating concrete wind turbine bases. Additionally, recent UK government intervention restricted a large Chinese-backed manufacturing plan at the site due to security concerns.
‘Mobilising EUR 1 Trillion in Investments’ | North Sea Countries, Industry, TSOs to Ink Offshore Wind Pact
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
Government officials from Belgium, Denmark, France, Germany, Ireland, Luxembourg, the Netherlands, Norway and the UK are set to sign a declaration confirming the ambition to build 300 GW of offshore wind in the North Seas by 2050, and an investment pact with the offshore wind industry and transmission system operators (TSOs) that is said to mobilise EUR 1 trillion in economic activity.
These three paragraphs add a lot of powerful detail.
Under the Offshore Wind Investment Pact for the North Seas, to be signed today (26 January) at the North Sea Summit in Hamburg, governments of the nine North Sea countries will commit to building 15 GW of offshore wind per year from 2031 to 2040.
The heads of state and energy ministers will also vow to de-risk offshore wind investments through a commitment to provide two-sided Contracts for Difference (CfDs) as the standard for offshore wind auction design. The pact also commits governments to remove any regulatory obstacles to power purchase agreements (PPAs), according to WindEurope, which will sign the pact on behalf of the industry.
On the industry’s side, the commitment is to drive down the costs of offshore wind by 30 per cent towards 2040, mobilise EUR 1 trillion of economic activity for Europe, create 91,000 additional jobs and invest EUR 9.5 billion in manufacturing, port infrastructure and vessels.
These two paragraphs say something about cost reductions.
The cost reduction of offshore wind is planned to be achieved through scale effects, lower costs of capital and further industrialisation supported by clarity and visibility on the project pipeline.
The transmission system operators (TSOs) will identify cost-effective cooperation projects in the North Sea, including 20 GW of promising cross-border projects by 2027 for deployment in the 2030s.
I hope there is a project management system, that can step into this frenzy, just as Artemis did in the 1970s with North Sea Oil and Gas.
The BBC has reported the story under a title of UK To Join Major Wind Farm Project With Nine European Countries.
this is the sub-title.
The UK is set to back a vast new fleet of offshore wind projects in the North Sea alongside nine other European countries including Norway, Germany and the Netherlands.
These six paragraphs add more detail.
The government says the deal will strengthen energy security by offering an escape from what it calls the “fossil fuel rollercoaster”.
For the first time, some of the new wind farms will be linked to multiple countries through undersea cables known as interconnectors, which supporters say should lower prices across the region.
But it could prove controversial as wind farm operators would be able to shop around between countries to sell power to the highest bidder – potentially driving up electricity prices when supply is tight.
Energy Secretary Ed Miliband will sign a declaration on Monday at a meeting on the future of the North Sea in the German city of Hamburg, committing to complete the scheme by 2050.
Jane Cooper, deputy CEO of industry body RenewableUK, said the deal would “drive down costs for billpayers” as well as increasing “the energy security of the UK and the whole of the North Sea region significantly”.
But Claire Countinho, shadow energy secretary, warned “we cannot escape the fact that the rush to build wind farms at breakneck speed is pushing up everybody’s energy bills.”
Claire Coutinho, as an outsider at present and a member of a party out of Government had to say something negative, but her negotiations when she was UK Energy Minister with her German opposite number, which I wrote about in UK And Germany Boost Offshore Renewables Ties, seem very much a precursor to today’s agreement.
French Companies Unite On Superconducting Cable Project For Distant Offshore Wind Farms
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
Air Liquide, CentraleSupélec, ITP Interpipe, Nexans, and RTE have joined forces to develop a project that connects distant offshore wind farms to shore via a High Voltage Alternating Current (HVAC) superconducting transmission system.
This introductory paragraph adds some detail.
The SupraMarine demonstrator project will study the electrical connection between offshore wind farms and the coastline using High-Temperature Superconducting (HTS) cables. Cooled by liquid nitrogen, the cables are said to transport electricity with near-zero energy loss.
Note.
- No details of the target distances are indicated.
- There is a detailed exploratory diagram.
It is certainly an ambitious project, but I feel it could have substantial uses.
I have a few thoughts and questions.
Can Sodium Metal Be Used For High Voltage Electrical Underground Cables?
Google AI answers this question as follows.
Yes, sodium metal was investigated and used in trial runs for high-voltage underground electrical cables in the late 1960s and early 1970s, as a potentially cheaper and more flexible alternative to copper and aluminum. However, it is not in common use today due to safety concerns and unfavorable lifecycle economics compared to aluminum.
When I was at ICI around 1970, they were researching the use of sodium for high voltage power cables.
- ICI had access to large amount of sodium chloride in Cheshire.
- The sodium metal can be obtained by electrolysis.
- Renewable electricity for electrolysis will be plentiful.
- Someone told me that their prototype cable was a polythene pipe with Sodium metal in the middle.
- I’ve read somewhere that sodium cables have interesting safe overload properties.
- I can understand the safety concerns and unfavorable lifecycle economics, especially where water is concerned.
Perhaps, French technology has improved in the sixty years?
Will Sodium Metal Be Used In The French Superconducting Cable?
Nothing has been disclosed!
But the office chat at ICI from those, who knew their sodium and their polythene, as they’d been working at ICI Mond Division for decades, was of the opinion that sodium/polythene cables were possible!
From The Diagram, It Looks Like Power Is Needed At Both Ends Of The Superconducting Cable
The diagram shows wind turbines at one end and the grid at the other end of the cable.
So will a battery or some other form of stabilisation be needed for when the wind isn’t blowing?
Will The French Superconducting Cable Have A High Capacity?
The basic capacity of a cable depends on three properties.
- The resistance of the cable.
- The cross-section area of the cable.
- The design of the cable must also be able too conduct away the heat generated by electricity flowing through.
Will The Technology Work For Interconnectors?
I don’t see why not!
EDF Developing Offshore Wind-Powered Hydrogen Production Project In French EEZ
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
EDF Power Solutions has invited applications for a tender for Environmental Impact Assessment (EIA) services and hazard studies as part of a project to develop an offshore hydrogen production station in France’s Exclusive Economic Zone (EEZ).
This is the first paragraph.
The project, dubbed HYODE (HYdrogen Offshore DunkerquE), will produce green hydrogen by coupling offshore wind farms with an offshore electrolyser near Dunkirk, France, and is planned to also include storage and transport by ship to port, forming what EDF describes as an “innovative solution” to help scale green hydrogen production.
I asked Google AI, if there are any operational offshore hydrogen electrolysers and received this answer.
Yes, there are operational offshore electrolyser projects, though large-scale, dedicated offshore hydrogen platforms are still in development. The first operational offshore production on an existing gas platform is planned for late 2024 with the PosHYdon project. Additionally, a pilot project in the UK is testing the full integration of a hydrogen electrolyser onto an existing offshore wind turbine, with another project in the Netherlands installing an offshore hydrogen production and storage platform.
But, I did get this page on page on the Ramboll web site, which is entitled The Rise Of Offshore Hydrogen Production At Scale, which has this introductory paragraph.
The stage is set for producing green hydrogen from offshore wind and desalinated seawater. Building on existing and proven technology, offshore wind farms have the potential to become future production hubs for green hydrogen production at scale to meet increasing demand.
That sounds very promising, especially, if proven technology is borrowed from the offshore oil and gas industry.

UK, French, And Irish Ports Join Hands In Global Floating Wind Collaboration
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
The UK’s Associated British Ports (ABP) has teamed up with France’s BrestPort and Ireland’s Shannon Foynes Port to establish the Global Floating Offshore Wind Ports Alliance (FLOW Ports Alliance) to help bring together major floating offshore wind ports across the world and unlock the technology’s full potential.
These first two paragraphs add more detail.
The FLOW Ports Alliance aims to recruit ports in Europe to collaborate on FLOW port design, standardisation, and best operational practices.
It plans to strengthen and accelerate compliant knowledge and experience exchange between ports, share best practices as they emerge through demonstration projects, and share innovations to the benefit of the global FLOW network.
Surely, a global network of ports that can handle construction, operation and maintenance of a range of floating wind platforms, is an excellent idea.
ENGIE And CDPQ To Invest Up To £1bn In UK Pumped Storage Hydro Assets
The title of this post, is the same as a news item from ENGIE.
These four bullet points act as sub-headings.
- Refurbishment programme to extend life of plants at Dinorwig and Ffestiniog will ensure the UK’s security of supply and support the transition to a low carbon energy future
- ENGIE owns 75% of the plants via First Hydro Company, a 75:25 joint venture with Canadian investment group CDPQ
- The two pumped storage hydro plants are the UK’s leading provider of power storage and flexibility, with 2.1GW of installed capacity
- They represent 5% of the UK’s total installed power generation capacity and 74% of the UK’s pumped storage hydro capacity
These three paragraphs give more details.
The preparation of a 10-year project of refurbishment at *ENGIE’s Dinorwig pumped storage station has begun, following an 8-year refurbishment at Ffestiniog, enabling the delivery of clean energy whenever needed.
These flexible generation assets, based in North Wales, are essential to the UK Government’s accelerated target of achieving a net zero carbon power grid by 2030. Together they help keep the national electricity system balanced, offering instant system flexibility at short notice. The plants are reaching end of life and replanting will ensure clean energy can continue to flow into the next few decades.
Re-planting could see the complete refurbishment of up to all six generating units at Dinorwig – a final investment decision is still to be made on the number of units to replace – while the re-planting at Ffestiniog will be completed at the end of 2025. The program also involves the replacement of main inlet valves – with full drain down of the stations – and detailed inspections of the water shafts.
It also looks like the complete refurbishment at Dinorwig will take ten years, as it seems they want to keep as much of the capacity available as possible.
When the replanting is complete, the two power plants will be good for twenty-five years.
Hopefully, by the time Dinorwig has been replanted, some of the next generation of pumped storage hydroelectric power stations are nearing completion.
The news item says this about Dinorwig.
Dinorwig, the largest and fastest-acting pumped storage station in Europe, followed in 1984 and was regarded as one of the world’s most imaginative engineering and environmental projects.
Dinorwig must be good, if a French company uses those words about British engineering of the 1980s.
DESNZ Launches Call For Evidence For Solar Carports In The UK
The title of this post is the same as this article on Solar Power Portal.
These three paragraphs introduce the article.
The UK Department for Energy Security and Net Zero (DESNZ) has launched a call for evidence to help increase the number of solar-powered carports in England, Wales, and Northern Ireland.
The likely result of this will be a mandate that car parks have a solar PV installation, as has been the case in France for some time.
Mandating solar on car parks has multiple benefits, which DESNZ is keen to emphasise. It says that a mandate would be a “better deal for motorists and businesses”
I may not be a fan of electric cars, but I’m certainly no fan of spreading solar panels over large areas of quality farmland.
There are some interesting statements.
Take this one.
DESNZ cites estimates that supermarkets, retail parks and offices could save up to £28,000 annually by installing solar carports (this figure calculated for an 80-space car park—the size that France mandates must be covered by solar PV) if all of the electricity generated by the solar array was used onsite.
£28,000 a year is not to be sneezed at!
And this one.
Earlier this year, Norwich-based RenEnergy, a solar carport provider, revealed that installing solar carports in more than half a million suitable parking spaces owned by UK businesses could generate 1.57GW of solar energy.
They do suggest that this figure only scratches the surface.
And then there’s this story from Bentley.
In 2019, Bentley Motors installed a solar car park at its headquarters in Crewe. The site’s 10,000 solar PV modules have a capacity of 2.7MW and cover an area of 16,426m². Along with other installed solar arrays and 6.6MW of battery energy storage, the car park enables all of Bentley’s manufacturing operations to be powered by solar or certified green energy.
How many other businesses could do that?
This Google Map shows the Bentley Motors site at Crewe.
Note.
- It appears to be a large site.
- Bentley employs over 4,000 employees at Crewe.
- In 2023, Bentley delivered 13, 560 cars.
- The solar car ports appear to be at the Western end of the site.
- There would appear to be a lot of scope to add more solar car ports at the Eastern end of the site.
Running along the Southern edge of the site is the North Wales Coast Line, which runs between Crewe and Chester and then on to North Wales.
I would have thought, that a case could be made out to have a station at the Bentley site for employees and visitors.
There also doesn’t seem to be the infrastructure, so that cars to some destinations can be delivered by train, like these from Toyota, which I photographed at Denmark Hill station, which were on the way to Europe, through the Channel Tunnel.
Perhaps sending luxury cars to their future owners by train is the wrong image.
France’s First And Only Operational Floating Wind Turbine Gets Lifetime Extension
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
Floatgen, the demonstration floating wind turbine installed at the SEM-REV offshore test site in France, has completed its planned five-year run but will operate for another five years as the demo project was decided to get a lifetime extension.
These are the first three paragraphs.
The floater, which consists of a 2 MW Vestas V80 wind turbine mounted on BW Ideol’s Damping Pool foundation, reached electricity production milestones several times since going into full operation in September 2018.
According to BW Ideol, Floatgen’s cumulated production has now surpassed 30 GWh, which the company ascribes to “the hydrodynamic properties and excellent sea-keeping capabilities” of its floating foundation.
Floatgen’s availability averaged 92.18 per cent between January 2021 and January 2024, with December 2023 standing out with a monthly production record of 922.026 MWh and a 61.96 per cent capacity factor, BW Ideol says.
Note.
- A three-year availability average of 92.18 % is surely very good.
- A 61.96 % capacity factor is better than most other floating wind farms, which are generally in the fifties.
With those figures, I suspect BW Ideol will be expecting, some orders soon.
This video shows a Floatgen being constructed.
Europe Installs Record-Breaking 4.2 GW Of Offshore Wind In 2023
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
Europe’s offshore wind industry brought online a record 4.2 GW of new capacity in 2023 and is expected to build around 5 GW of offshore wind annually over the next three years, according to WindEurope data. However, this is still not enough to meet the continent’s 2030 climate and energy security targets, WindEurope added.
These are the first two paragraphs.
The overall offshore wind capacity installed in 2023 was 40 per cent higher than in 2022. Of the 4.2 GW of new capacity, 3 GW was in the EU, an increase of 2.1 GW year on year, WindEurope said.
The Netherlands, France, and the UK installed the most new capacity, including the 1.5 GW Hollandse Kust Zuid offshore wind project in the Netherlands, according to the organisation.
But where are the Germans?
They’ve got plenty of steel and sea, Siemens make a lot of wind turbines and they certainly need the electricity.
In 2023, Germany generated their electricity as follows.
- Brown coal (17.7%)
- Hard coal (8.3%)
- Natural gas (10.5%)
- Wind (32.0%)
- Solar (12.2%)
- Biomass (9.7%)
- Nuclear (1.5%)
- Hydro (4.5%)
- Oil (0.7%)
- Other (2.9%)
By comparison the UK’s figures were.
- Coal (1%)
- Natural gas (32%)
- Wind (29.4%)
- Solar (4.9%)
- Biomass (5%)
- Nuclear (14.2%)
- Hydro (1.8%)
- Storage (1%)
- Imports (10.7%)
Note.
- The Germans use a lot of coal.
- The UK uses a lot more natural gas.
- Despite the much-criticised Drax, the Germans use twice as much biomass as we do.
- The UK uses tens times more nuclear.
The Wikipedia entries for German and UK wind power make interesting reading.
