Crown Estate’s Revenue From Existing Offshore Wind Farms 20 Pct Higher, Operating Profit Dips As Round 4 Projects Enter Construction Phase
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
The Crown Estate reported a decline in annual operating profit to GBP 1.2 billion (approximately EUR 1.4 billion) from GBP 1.4 billion (approx. EUR 1.6 billion) in the previous year due to lower offshore wind Round 4 option fee income, as the Round 4 projects started entering the construction phase. Excluding the Round 4 option fees, operating profit rose 5 per cent to GBP 370 million (approx. EUR 435 million), while revenue from existing offshore wind farms increased 20 per cent to GBP 117 million (approx. EUR 138 million)
These four paragraphs add more details.
Over the year, the Crown Estate returned GBP 487 million (approx. EUR 573 million) to HM Treasury, bringing total contributions to GBP 5.1 billion (approx. EUR 6 billion) over the past decade, according to its financial report released on 25 June.
Alongside the financial results, the UK seabed manager highlighted that offshore wind capacity in its waters has reached 13 GW, up from 12 GW, with 36 wind farms now operating in its marine portfolio.
The pipeline of offshore wind capacity has increased to 56 GW, with an expanding offshore leasing and development programme as early Round 4 projects enter construction.
In the Offshore Wind Seabed Leasing Round 4, held in 2021, the Crown Estate selected six projects, which signed their Agreements for Lease in 2023, kicking off the three-year period during which the developers were paying annual option fees.
In Offshore Wind In 2030 – Calculated June 2026, I showed that the offshore wind capacity will have increased to 56 GW, sometime in 2031-2032.
How Much Income Will There Be In 2027-2032 from UK Wind Farms?
I asked Google AI the question in the title of this section and received this answer.
UK wind farm industry revenues are forecast to surpass £6 billion annually heading into 2027, driven by expanding capacity and inflation-adjusted contracts. Between 2027 and 2032, overall sector income will scale rapidly as capacity aims to double and up to £5 billion is pumped into the supply chain.
The economic landscape for UK wind generation features the following financial projections and parameters:
Industry Revenue & Growth: The UK wind power generation market is projected to expand at a Compound Annual Growth Rate (CAGR) of over 15% through 2031. The rapid expansion of both onshore and offshore capacity will push total market revenues well into the double-digit billions by 2032.
Contract for Difference (CfD) Revenues: Wind farms are heavily shielded from market volatility by index-linked strike prices. For instance, recent offshore projects have secured delivery rates as low as $37.35 per megawatt-hour (MWh). Conversely, older assets are transitioning out of initial subsidy schemes, moving into merchant wholesale pricing or new contracts by 2027.
Macroeconomic Contribution: Every additional gigawatt (GW) of offshore wind capacity adds an estimated £2 billion to £3 billion to the wider UK economy.
The Crown Estate Earnings: Acting as the UK seabed manager, The Crown Estate generates significant income from offshore wind leasing, having reported operating profits of over £1.2 billion and planning to retain up to 60% of its revenue to reinvest in the energy sector.
Landowner & Community Economics: For utility-scale farms, participating landowners generally earn between 5% and 6% of the annual turnover from wind farms, equating to around £40,000 per year for a single large turbine. Domestic turbines can earn up to £702 annually under the Smart Export Guarantee (SEG), depending on the specific supplier tariff.
I believe that with a similar growth of solar energy, the renewable energy produced in the UK in 2032 will be beyond our wildest dreams.
Encomara’s Floating Wind Installation Technology Gets ABS Design Approval
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
Encomara’s floating wind installation technology, Squid, has received Product Design Assessment (PDA) certification from the American Bureau of Shipping (ABS)
These three paragraphs add more details.
The PDA follows an Approval in Principle (AiP) granted by ABS in November 2025 and moves the system a step closer to commercial deployment, according to Encomara, as it advances the technology along its qualification pathway towards Technology Readiness Level assessment and market adoption.
The technology is developed by Encomara and manufactured by Aurora Energy Services (AES), which acquired the Aberdeen-based company in 2025.
Squid integrates pre-installed mooring lines and electrical connections into a single subsea unit, enabling floating wind turbines to be connected using a “plug-and-play” approach.
In some ways the project reminds me of a floating oil and gas production platform, on which I did the calculations.
But the Balaena Structures design never sold a platform and the company, which was based in Cambridge, folded.
Encomara have a web site, which is well worth a visit.
Does Floating Wind Power Have A Higher Capacity Factor Than Fixed Foundation Wind Power?
I asked Google AI the question in the above sub-title and received this answer.
Yes. Floating wind power typically achieves higher capacity factors than fixed-foundation wind power.
The main reasons for this performance edge include:
Stronger, More Consistent Winds: Floating platforms allow turbines to be placed much further offshore, where wind speeds are higher, steadier, and less turbulent.
Access to Deeper Waters: Over 80% of deep-water offshore wind resources exist in waters too deep for fixed-bottom structures.
Performance Comparisons: Fixed offshore wind turbines typically see capacity factors ranging between 45% and 60% (depending on the location), whereas floating installations can push past 60%. For instance, the Hywind floating wind farm in Scotland achieved a capacity factor exceeding 65% in its first months of operation.
Despite this higher generation yield, floating wind technology is generally more complex and features higher installation and capital costs than fixed-bottom turbines.
I also believe that some of the floating wind technology, lends itself to advanced production and installation methods.
Trump Administration Withdraws Appeal, Leaving Wind Energy Leasing And Permitting Freeze Vacated
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
The Trump Administration has withdrawn its appeal of a federal court ruling that vacated the section of its January 2025 Presidential Wind Memorandum that halted federal leasing and permitting activities for onshore and offshore wind projects, leaving the court’s decision in place and the wind permitting and leasing freeze overturned.
These two paragraphs add more details.
The US Court of Appeals for the First Circuit has granted the federal government’s motion to voluntarily dismiss its appeal of a December 2025 ruling by the US District Court for the District of Massachusetts, which found the challenged section of the Presidential Wind Memorandum unlawful and vacated it in its entirety.
With the dismissal, the district court’s ruling remains in force, meaning the indefinite nationwide pause on wind energy leasing and permitting activities can no longer be enforced.
To quote one of my favourite accountants and a very good friend.
Trump has been screwed, glued and tattooed.
Thankfully, he also has appeared to have given up fairly quickly and has stopped throwing good money after bad.
GWEC Calls For Faster Offshore Wind Deployment As Global Capacity Nears 100 GW
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
The Global Wind Energy Council (GWEC) has called on governments worldwide to accelerate offshore wind deployment and treat offshore wind projects as critical energy infrastructure, warning that a faster build-out is necessary to strengthen energy security and reduce exposure to future energy market shocks
These two paragraphs add some more detail.
The industry is approaching a major milestone of 100 GW of installed offshore wind capacity globally, according to GWEC’s 2026 Global Offshore Wind Report, released on 9 June at the APAC Wind Energy Summit in Hanoi, Vietnam.
The report shows that 9.3 GW of new offshore wind capacity was grid-connected worldwide in 2025, a 16 per cent increase compared to the previous year and the third-highest annual total on record. Global installed offshore wind capacity reached 92.5 GW by the end of 2025.
These are some points from the article.
- China remained the world’s largest offshore wind market in 2025, commissioning 6.6 GW of new capacity and increasing its total installed offshore wind capacity to 48.4 GW.
- Europe added nearly 2 GW across the UK, Germany and France, with the UK accounting for just over 1 GW of new installations.
- Despite the positive outlook, GWEC said project development continues to be hindered by permitting delays, grid constraints, supply chain bottlenecks and shortcomings in auction design.
- The average size of offshore wind turbines installed in 2025 exceeded 10 MW for the first time, reaching 10.3 MW.
It certainly looks like offshore wind power is going well.
Is The UK Developing Sea-Drones To Protect Wind Farms?
I asked Google AI the question in the title of this post and received this answer.
Yes, the UK is actively developing and utilizing sea-drones (and autonomous boats) for its offshore wind farms. This technology is being used to protect the farms by patrolling subsea infrastructure, inspecting underwater turbine foundations, and delivering heavy equipment to mitigate human risk.
Here is a look at how sea drones and autonomous systems are being developed and used for the UK’s offshore energy sector:
Subsea Security and Patrolling: The UK and NATO are highly focused on protecting critical subsea cables and wind networks from adversarial interference. Firms like Aberdeen-based Honuworx have been contracted to develop autonomous underwater vehicles capable of prolonged remote operation for defense and infrastructure surveillance.
Underwater Structure Inspection: Projects like the UNITE program (led by Heriot-Watt University and supported by the National Robotarium) are testing AI-controlled underwater robots to operate in turbulent seas and maintain offshore wind infrastructure. Meanwhile, Beam (an offshore wind services company) successfully deployed the world’s first AI-driven autonomous underwater drone at Scotland’s Seagreen wind farm, cutting inspection times in half.
Sailing Drones & Remote Operations: Energy companies like Vattenfall are controlling uncrewed surface vessels (USVs) and sailing drones from remote operation centers in Aberdeen to patrol and keep North Sea wind farms safe and efficient.
Heavy-Lift Cargo Drones: Beyond sea drones, energy giant Ørsted has utilized giant autonomous drones to deliver heavy equipment—like 70kg boxes of safety gear—directly to the tops of offshore wind turbines in the UK, removing the need for ships and cranes in rough seas
We should fight fire with innovation.
Crown Estate To Re-Tender 1.5 GW Offshore Wind Site Relinquished by EnBW And JERA Nex BP
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
The Crown Estate will launch a competitive tender process next month to bring the 1.5 GW Morgan offshore wind project in the Irish Sea back to market, with plans to appoint a new developer by late 2026.
These two paragraphs add more detail.
The Morgan site was originally awarded through Offshore Wind Leasing Round 4 in 2021, but development was discontinued in January 2026 by the joint venture between EnBW and JERA Nex BP, which held the lease rights.
After EnBW decided to exit the Morgan and Mona offshore wind projects in the UK, its joint venture partner JERA Nex BP acquired EnBW’s stake in 1.5 GW Mona, while the joint venture discontinued the development of the Morgan project and returned the lease rights to the Crown Estate.
There is no Morgan web site, but there is a joint web site with the Morecambe wind farm, which also has its own web site.
The joint web site has a home page showing both Morgan and Morecambe wind farms connecting to Penwortham substation.
In Mooir Vannin Offshore Wind Farm, I say that this web farm will also have a connection to the Penwortham substation.
There does seem a lot of bitterness about using the Penwortham substation being built.
This Ørsted map shows the large number of wind farms in the Irish Sea.
Note.
- Mooir Vannin is a 1.4 GW wind farm being developed to the East of the Isle of Man
- Morgan wind farm would have been a 1.5 GW wind farm to be South of Mooir Vannin.
- Mona wind farm will be a 1.5 GW to the South of Morgan.
- Mona will connect to the North Wales coast.
- Morecambe will be a 480 MW wind farm to the East of Morgan and Mona.
- Mooir Vannin will connect to the Isle of Man.
- Morgan and Morecambe wind farms were all planned to connect to the Penwortham substation.
- Mooir Vannin will additionally connect to the Isle of Man.
It will be interesting to see, what proposals are put to the Crown Estate for a replacement of the Morgan wind farm.
I wouldn’t be surprised to see something to do with offshore production of hydrogen, as there is much more hydrogen production on the East side of the UK, due to the massive German AquaVentus project.
JERA Nex BP, EnBW Submit Morven Offshore Wind Farm Application
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
A joint venture between JERA Nex BP and EnBW has submitted Section 36 consent applications for the Morven offshore wind farm to the Scottish government
These two paragraphs add a few details.
The developer secured the seabed rights for the Morven offshore wind farm as a single project in the ScotWind Leasing Round in 2022 and split it into two separate projects during the early development phase.
Located around 60 kilometres off the coast of Aberdeenshire at its closest point, the site is planned to house Morven North and Morven South, which would have a combined installed capacity of up to 3 GW and around 190 wind turbines in total.
Morven Offshore Wind Farm now has a comprehensive web site.
The web site says that the electricity will be brought ashore at Hawthorn Pit.
This Google Map shows the location of Hawthorn Pit.
Note.
- Hawthorn Pit is indicated by the red arrow.
- Sunderland is at the top of the map on the coast.
- Aura Power has already obtained planning permission for Hawthorn Pit solar farm, which will be up to 49.9 MW.
- Zenobe are developing a battery-energy-storage-system(BESS) 1.5 km to the South-East of the new Hawthorn Pit substation, which will have an output of 300 MW. Sloppily, there is no detail on capacity, but Google AI indicates, it is a 300 MW/600 MWh battery.
- Hawthorn Pit substation is also the expected to be the Southern end of Eastern Green Link 1, which will help to bring Scottish wind power to England, which will be a 2 GW undersea interconnector to Torness.
In Murphy Starts Work On £2.5bn Eastern Green Link 1, I detail the start of building of Eastern Green Link 1 and say it should be operational by 2029.
When Is The Morven Offshore Wind Farm Expected To Be Commissioned?
I asked Google AI the question above and received this answer.
The 2.9 GW Morven offshore wind farm is expected to be fully commissioned and operational between 2031 and 2035, with initial grid connections and power export potentially starting as early as 2030.
The timeline for full deployment of the Morven Offshore Wind Farm remains somewhat flexible as it depends on final planning approvals and connection offers from the National Energy System Operator (NESO).
The Cables For The Morven Offshore Wind Farm And Eastern Green Link 1
This map clipped from the Morven Offshore Wind Farm web site, shows the locations of Aberdeen, Hawthorn Pit and the Morven Offshore Wind Farm.
Note.
- The location of the Morven wind array was first mentioned in June 2020, as part of ScotWind by Crown Estate Scotland.
- The development of Eastern Green Link 1 was first mentioned in May 2021, by National Grid.
- Torness is to the East of Edinburgh.
- Eastern Green Link 1 connects Torness and Hawthorn Pit.
- the Morven wind array connects to England at Hawthorn Pit.
Over the last few years National Grid and other companies have been developing a technique called offshore hybrid assets, which I describe in What Are Offshore Hybrid Assets?.
An offshore hybrid asset typically connects two countries via a large offshore wind farm, which can then send electricity to both countries.
In a traditional design, there would need to be.
- A 2 GW cable between Torness and Hawthorn Pit.
- A 2.9 GW cable between Morven and Hawthorn Pit.
In the Offshore Hybrid Asset design, there would need to be.
- A 2 GW cable between Torness and Morven
- A 2.9 GW cable between Morven and Hawthorn Pit.
I suspect cable would be saved.
This map shows the position of each ScotWind Leasing wind farm.
Note.
- The numbers are Scotwind’s lease number in their documents.
- Morven is ScotWind lease number 1.
- Eastern Green Link 1 is one of four interconnectors down the East Coast of the UK.
- I have added up the ScotWind lease numbers 1-6 and they total 10.5 GW.
That would be a lot of power to capture just by converting the four Eastern Green Link interconnectors into offshore hybrid assets.
How Will Aquaventus Connect To Aberdeen?
This is RWE’s description of AquaVentus, which is sub-titled Hydrogen Production In The North Sea.
Hydrogen is considered the great hope of decarbonisation in all sectors that cannot be electrified, e.g. industrial manufacturing, aviation and shipping. Massive investments in the expansion of renewable energy are needed to enable carbon-neutral hydrogen production. After all, wind, solar and hydroelectric power form the basis of climate-friendly hydrogen.
In its quest for climate-friendly hydrogen production, the AquaVentus initiative has set its sights on one renewable energy generation technology: offshore wind. The initiative aims to use electricity from offshore wind farms to operate electrolysers also installed at sea on an industrial scale. Plans envisage setting up electrolysis units in the North Sea with a total capacity of 10 gigawatts, enough to produce 1 million metric tons of green hydrogen.
RWE have also put this AquaVentus video on their web site.
Note, that in the video AquaVentus connects Germany to Denmark, Norway, The Netherlands and Aberdeen and Humberside in the UK.
I asked Google AI, the question in the title of this section, and received this answer.
AquaVentus connects to Aberdeen through a strategic infrastructure partnership with Hydrogen Scotland. The two organizations are integrating offshore wind power, offshore electrolysis, and a shared cross-border pipeline to link Scottish renewable generation with European industrial markets.
The connection strategy relies on a multi-stage approach across the North Sea:
Offshore Production & Transmission: AquaVentus aims to produce green hydrogen directly offshore. It will be transported via a pan-European pipeline network—such as the planned 400 km AquaDuctus to link offshore hubs with both the UK and mainland Europe.
Scottish-German Export Corridor: Building on previous research like the Scot2Ger study, this pipeline corridor directly connects Scotland’s abundant offshore wind resources to European demand, establishing Aberdeen as a critical origin node.
Integrated Energy Backbone: The initiative champions hybrid connection concepts (combining both power cables and hydrogen pipelines). This allows for maximum flexibility when integrating Aberdeen’s local onshore hydrogen infrastructure with broader transnational energy grids.
I will now ask Google AI some supplementary questions about AquaVentus in UK waters.
“Will AquaVentus Produce Hydrogen In UK Waters?”
Google AI gave this reply.
Yes, AquaVentus plans to produce green hydrogen in UK waters. The German-led consortium has partnered with Hydrogen Scotland to harness Scotland’s offshore wind potential for large-scale, cross-border hydrogen production and export.
Key Details of the UK-German Initiative
Production Scale: The initiative aims to install 10 gigawatts (GW) of offshore electrolysis capacity in the North Sea by 2035, producing up to 1 million metric tonnes of green hydrogen annually.
The “Pipes and Wires” Model: Offshore wind parks will be equipped with hybrid connection concepts, providing the flexibility to either send electricity directly to the grid or convert it into hydrogen via offshore electrolysers.
Transportation: The produced hydrogen will be transported to land via a shared transnational subsea pipeline corridor, linking Scottish resources to Germany and mainland Europe.The partnership is specifically aimed at creating a North Sea hydrogen corridor to boost energy security and build the foundational European Hydrogen Backbone.
“Will AquaVentus Land Hydrogen In Scotland?”
Google AI gave this reply.
Yes, the German-led AquaVentus initiative plans to land green hydrogen in Scotland as part of a coordinated North Sea energy corridor.
The cross-border initiative involves the following components:
The Pipeline Connection: A key part of the plan is the AquaDuctus offshore subsea pipeline, designed to collect green hydrogen produced from central North Sea wind farms and land it on the coast.
Scottish Partnership: Hydrogen Scotland and AquaVentus have formalized a Memorandum of Understanding to combine Scotland’s massive offshore wind potential with German infrastructure and electrolysis expertise.
Export Ambitions: Scotland aims to produce up to 3.3 Mt of green hydrogen per year by 2045, heavily relying on pipelines and networks to export this to mainland European hubs like Germany.
Offshore Facilities: The broader initiative plans to install 10 GW of offshore electrolysis capacity in the North Sea to produce up to 1 million tonnes of hydrogen annually.
Note that Google AI has told me that a Megatonne of hydrogen is currently worth around £2.5-5 billion.
“Will AquaVentus Connect To Any Of The ScotWind Leasing Wind Farms?”
Google AI gave this reply.
Yes, AquaVentus plans to link Scottish offshore wind resources (including ScotWind farms) to mainland Europe. Through an agreement with Hydrogen Scotland, AquaVentus intends to utilize hybrid “pipes and wires” infrastructure to transmit power or convert it into green hydrogen for direct pipeline transport.
The partnership serves several strategic goals:
The “Pipes & Wires” Concept: Wind farms built under the ScotWind leasing round will have the flexibility to either route electricity to the UK grid or convert it into green hydrogen via offshore electrolysers.
Cross-Border Pipelines: The hydrogen generated by Scottish offshore wind is targeted to be fed into the planned AquaDuctus pipeline, which forms a transnational energy corridor connecting the UK to Germany and the rest of Europe.
Policy Integration: AquaVentus is actively advocating for legal reforms to accommodate these cross-border hybrid connections, allowing direct pipeline integration for future offshore parks.
I believe these ScotWind Leasing wind farms could be connected to AquaVentus.
- 1 – Morven – 2.9 GW – JERA Nex BP, EnBW
- 2 – Ossian – 2.6 GW – SSE Renewables
- 3 – Bellrock – 1.2 GW – Falck Renewables
- 4 – CampionWind – 2 GW – Scottish Power, Shell
- 5 – Muir Mhòr – 0.8 GW – Vattenfall
- 6 – Bowdun – – 1 GW – Thistle Wind Partners
Note.
- All companies are major energy companies.
- The wind farms are in a cluster to the South-East of Scotland.
- Wind farms 2-5 are floating, and 1 and 6 are fixed.
- There is a maximum power of 10.5 GW.
- These wind farms would not need to be shut down, when there was too much wind, if the excess electricity could be converted into hydrogen.
- The “Pipes & Wires” Concept would allow all energy generated to be transferred to shore, either as electricity or hydrogen.
Cables would need to be laid to perform the functions of the Eastern Green Links 1-4.
- Eastern Green Link 1 – Torness and Hawthorn Pit
- Eastern Green Link 2 – Peterhead and Drax
- Eastern Green Link 3 – Westfield and Lincolnshire
- Eastern Green Link 4 – Peterhead and Lincolnshire
Eastern Green Link 5 is under development between Aberdeenshire and Lincolnshire.
“Is Anderby Creek An Important Node In The Electricity Grid?”
Google AI gave this reply.
Yes, Anderby Creek has become a highly important landfall location for the UK’s electricity grid, acting as a crucial connection point for high-capacity subsea cables bringing renewable energy from Scotland and offshore wind farms into England.
Its role in the national grid’s infrastructure centers on several major “superhighway” projects:
Eastern Green Link 5 (EGL 5): This £3bn National Grid project involves a 585km subsea High Voltage Direct Current (HVDC) cable carrying up to 2 GW of clean power (enough for two million homes) from Aberdeenshire, Scotland, to Anderby Creek.
Eastern Green Links 3 & 4 (EGL 3 / EGL 4): These are additional massive subsea cable projects that also plan to make landfall at Anderby Creek to transport Scottish wind energy down the UK coastline.
Offshore Wind Export Cables: Beyond long-distance transmission, the village already hosts export cables from local offshore wind developments like the Triton Knoll Wind Farm.
Because of the massive volume of power coming ashore, Anderby Creek serves as the starting point for significant onshore infrastructure. The cables transition underground at the beach and run roughly 8km inland to a proposed new converter station near Bilsby/Alford, where the power is converted and integrated into the broader Great Grid Upgrade.
“Will AquaVentus Have Access To The UK’s hydrogen Storage On Humberside?”
Google AI gave this reply.
Yes. Through a strategic partnership with Hydrogen Scotland, the AquaVentus initiative aims to establish cross-border offshore infrastructure that connects the central North Sea with existing and planned hydrogen networks across the UK, including those on Humberside.
The pipeline infrastructure associated with AquaVentus is envisioned to reach the UK just south of the massive hydrogen storage facilities located in East Yorkshire. While the German offshore pipeline (like AquaDuctus) is focused on landing green hydrogen into Germany, the broader AquaVentus framework is designed to integrate with British transmission networks and link to underground cavern storage in the UK.
On Humberside, major energy giants (including Centrica, Equinor, and SSE Thermal) are developing the integrated Humber Hydrogen transport and storage network. This system encompasses large-scale hydrogen storage at the Aldbrough Hydrogen Storage site and Rough Gas Storage. Because the AquaVentus UK branch connects to the Humber area’s onshore network, it positions the initiative to take advantage of these regional storage assets as a cornerstone for international trade and domestic energy resilience.
I think this is key as it gives AquaVentus access to very large hydrogen storage.
Conclusion
It almost looks to me, that National Grid and AquaVentus are combining their pipes and wires between the Southern North Sea and Aberdeen.
- Hydrogen offtake for Germany will be at Wilhelmshaven.
- Hydrogen offtake for England will be at Humberside.
- Hydrogen offtake for Scotland will be at Aberdeen.
- Electricity offtake for Germany will be at Wilhelmshaven.
- Electricity offtake for England will be at Anderby Creek.
- Electricity offtake for England will be at Hawthorn Pit.
- Electricity offtake for Scotland will be at Torness.
- Electricity offtake for Scotland will be at Aberdeen.
Note.
- There will probably be other connections to onshore locations and offshore wind farms.
- Hydrogen imports will be possible from Denmark, Norway and The Netherlands direct into AquaVentus.
Murphy Starts Work On £2.5bn Eastern Green Link 1
The title of this post, is the same as that as this article on Construction Enquirer.
This is the sub-heading.
Murphy has started work on its first package on the vast £2.5bn Eastern Green Link 1
These two paragraphs add more detail.
The joint venture between SP Energy Networks and National Grid Electricity Transmission will see the installation of a 196km, high voltage, subsea electricity cable between Torness in East Lothian, Scotland, and Hawthorn Pit in County Durham.
Murphy is one of the main works contractors alongside Metlen, GE Vernova and Prysmian.
Murphy’s task seems to be to design and build the new substation, integrate it with the existing one and connect it all to Eastern Green Link 1 and other assets. Work is expected to complete in March 2028.
Google AI predicts that Eastern Green Link 1 will be commissioned by 2029, so it should be up and running before the expected election helping to balance and stabilise Scottish and English wind power at a rate of up to 2 GW day and night.
The March Of The Batteries
One of my Google alerts picked up this story from the Solar Power Portal, which is entitled Gresham House To Acquire 480MW BESS, Completes Financing On 397MW Portfolio.
This is the sub-heading.
Gresham House Energy Storage Fund signed a Sale and Purchase agreement (SPA) for the conditional acquisition of a 480MW BESS project, while also completing funding on a 397MW portfolio that will begin construction.
I asked Google AI, “How Big Is Gresham Houuse’s Portfolio Of Batteries?” an received this answer.
Gresham House Energy Storage Fund (GRID) operates a portfolio exceeding 1GW of utility-scale battery capacity in the UK, with an active pipeline of future and recently financed projects.
Their operational capacity features:
Operational Capacity: Exceeds 1GW (approx. 1,072MW/1,701MWh) across dozens of sites.
Market Share: Owns roughly 17% to 20% of all utility-scale batteries in Great Britain.
Haven’t they done well!
When Will Highview Power Complete The Carrington Battery?
Highview Power is building a 50 MW/300 MWh liquid air battery at Carrington, near Manchester.
I asked Google AI,the title of this section and received this reply.
Highview Power’s Carrington liquid air energy storage facility in Greater Manchester is scheduled to be operational by late 2026.
The grid stabilization phase is set to begin early in the year, with full long-duration operations following shortly after.The £300 million project at the Trafford Low Carbon Energy Park is a pioneering commercial-scale “cryobattery” that liquefies and stores air to capture excess renewable energy.
Key details of the completed facility:
Capacity: 300 MWh of storage (delivering 50 MW for six hours)
Reach: Capable of supplying electricity to approximately 480,000 homes
Technology: Liquid Air Energy Storage (LAES)
When Will Highview Power Complete The Livingstone Battery?
Highview Power is building a300 MW/3.2 GWh liquid air battery at Livingstone near Glasgow.
I asked Google AI, the title of this section and received this reply.
Highview Power is not currently building a battery in Livingstone. They are developing a major \(2.5 \text{ GWh}\) liquid air energy storage (LAES) plant in Hunterston, Scotland, which is scheduled to come online by 2030.
According to the Highview Power web site, a 300 MW/3.2 GWh “cryobattery” is being built at the site.
How Much Offshore Wind Power Will Be Installed This Year?
In UK Offshore Wind In 2030 – Calculated May 2026, I said that 2635 MW would be commissioned this year.
Conclusion
We’re running hard, but will we keep ahead of the tsunami of offshore wind and solar panels we are installing.
In UK Offshore Wind In 2030 – Calculated May 2026, my latest calculations show that by 2036, we will have installed 61,337 MW of offshore wind alone.
How Many Of Their 300 MW/3.2 GWh Liquid Air Batteries Do Highview Power Think They Can Install?
I asked Google AI, the title of this section and received this reply.
Highview Power plans to install several of their 300 MW/3.2 GWh “Millennium Series” cryogenic plants. They are specifically developing two initial flagship sites in the UK, with the intention to scale up rapidly over the next decade to capture a significant share of national long-duration energy storage targets.
Highview Power is executing a multi-billion-pound programme to build out these multi-technology storage facilities, which combine liquid air energy storage and lithium-ion batteries.
The two primary 3.2 GWh projects advancing through the UK regulatory system include:
Hunterston, North Ayrshire (Scotland): Slated as the first of the Millennium Series, designed to provide up to 3.2 GWh of capacity (powering around 650,000 homes).It is advancing through the regulatory assessment and construction phases.
Killingholme, Lincolnshire (England): A second 3.2 GWh facility.
Both the Hunterston and Killingholme sites were deemed eligible for support under the UK government’s “cap and floor” super-battery scheme.
Two 300 MW/3.2 GWh “Millennium Series” cryogenic plants will do very nicely!
Engineering is the science of the possible, whereas politics is dreams of the impossible.
Mooir Vannin Offshore Wind Farm
This is a wind farm off the Isle of Man, that I missed as it is not on Wikipedia’s List of Offshore Wind Farms In The United Kingdom.
But it does have a web site, which has this handy map.
Note.
- The wind farm will have a capacity of 1.4 GW.
- Ørsted is building the web farm.
- It has planning permission.
- The operations base for the proposed Mooir Vannin Offshore Wind Farm will be located at Douglas Harbour on the Isle of Man.
- The Port is Owned By The Isle Of Man Government.
- Anticipated operational start date is the mid 2030s. I’ll assume 2035.
- According to the web site, connection will be to Douglas on the Isle of Man and Penwortham, Lancashire in the UK.
- Penwortham is part of Preston.
- Penwortham substation already has a 50 MW/50 MWh BESS and may get a bigger one.
- Current fossil-fuel power stations on the Isle of Man, include a number of diesel power stations and a 64 MW CCGT. They also have a 23 MW steam generator.
It looks like Mooir Vannin is large enough to give the island a carbon-free energy supply, backed up, by the UK National Grid at Penwortham.
I asked Google AI, “If The Isle of Man Was Going Into The Data Centre Business”, and received this reply.
The Isle of Man is actively positioning itself as a premier hub for data centres, tech firms, and AI companies. The government is utilizing its robust infrastructure, strong regulatory environment, and competitive tax policies to attract high-value data businesses to the island.
It also looks like they have a water system, that has a hydro-electric power-station.
Ørsted Is Danish
Ørsted is Danish and all of those countries to the North East of the UK have lots of islands.
So I asked Google AI, this question.”Does Denmark Have Any Islands With Power Stations?”, and received this comprehensive answer.
Yes, Denmark has several islands with power stations, ranging from natural islands utilizing large wind and biomass facilities to massive, pioneering “Energy Islands” built specifically as offshore power hubs.
Key Examples Include:
Bornholm (Baltic Sea): Designated as a major green “Energy Island” hub. It functions as a massive collection and distribution point for surrounding offshore wind farms, routing renewable energy to both the Danish grid and neighboring countries like Germany.
SamsØ (Kattegat strait): Known globally as a renewable energy island.
It is entirely powered by local onshore and offshore wind turbines and uses a mix of solar and battery storage systems to manage its energy needs, including marina charging.
North Sea Energy Island (VindØ): This is a colossal artificial island project (located roughly 80–100 km off the coast of Jutland) designed to act as an offshore power plant.
It acts as a hub to harvest and convert wind energy from hundreds of surrounding turbines.
Are Ørsted and Highview Power Still Talking?
In Highview Power, Ørsted Find Value In Integrating Offshore Wind With Liquid Air Energy Storage, it appeared that they still were.
As it appears that Highview Power’s Liquid Air Energy Storage can be sized to the application, I wouldn’t be surprised to see one of their batteries on an island powered by Danish wind turbines.
In Is Sumitomo Heavy Industries Highview Power Energy Storage System On Line At Hiroshima?, I describe how a Highview Power application, that uses cold, solar panels and a small Highview Power battery to increase the efficiency of a CNG Terminal.
How Many Of The UK’s Power Stations Are On Islands?
I asked Google AI this question and I received this answer.
There are three major, conventional thermal power stations on the UK’s offshore islands (two in Scotland and one in the Channel Islands), alongside several small-scale community-owned renewable plants that operate entirely off-grid.
The main island-based power stations include:
Lerwick Power Station (Shetland): A 66-73 MW diesel-fired plant commissioned in 1953. It provides a baseline of electricity for the Shetland mainland.
Sullom Voe Terminal Power Station (Shetland): An independent gas-fired station (roughly 92 MW capacity).
Its primary purpose is to serve the Sullom Voe gas terminal, but it also supplies the Shetland grid.
Queen’s Road Power Station (Jersey): A multi-engine facility in the Channel Islands that uses a mix of gas turbines and diesel generators to maintain island capacity.
(Note: Major UK islands, like the Isle of Wight, Anglesey, and the Isle of Skye, are physically connected to the mainland electricity grid via subsea cables, so they do not house their own large-scale, standalone power stations).
Beyond these conventional thermal stations, several smaller Scottish islands run on micro-grid, renewable-only power stations.
For instance:The Isle of Eigg: Powered entirely by a micro-grid of hydro, wind, and solar, completely disconnected from the UK grid.
It looks to me, that the Isle of Man, Shetland and Jersey, are the three most likely islands to get upgraded power systems and it also looks like Ørsted have the experience to make a good fist of it.
Conclusion
I have asked the question, I asked for the UK for a range of countries and I have received some interesting answers from Google AI. But the general trend seems to be to use appropriately-size medium-size and upwards, zero-carbon power stations with microgrids as on the Island of Eigg in the UK.
But I do believe that applying the technology that Ørsted, Highview Power and others are rolling out, that we can give the remote islands and places of Buckminster Fuller’s Spaceship Earth, the zero carbon power they need.
