Port Talbot To Become Offshore Wind Hub For Celtic Sea
The title of this post, is the same as that of this article on the BBC.
This is the sub-heading.
Port Talbot will become the first dedicated hub for floating offshore wind in the Celtic Sea.
These four introductory paragraphs add some detail.
Associated British Ports (ABP) will begin detailed design and engineering work on new port infrastructure after securing grant funding of up to £64m from the UK government.
The project will support the assembly and deployment of floating turbines that will operate in deeper waters off the Welsh coast. ABP said the development could support thousands of jobs and attract hundreds of millions of pounds in further investment.
The UK government said the new port would help deliver clean, homegrown electricity, protect households from volatile fossil fuel markets and create up to 5,000 new jobs.
Redeveloping the port to handle the assembly of wind turbines could position Port Talbot at the centre of a fast-growing clean energy sector.
I have some thoughts.
How Much Wind Power Is Planned For The Western Approaches?
In Ocean Winds Enters Lease Agreement With Crown Estate For 1.5 GW Celtic Sea Floating Wind Project, I published this Google AI estimate of the wind power, that could be developed in the Western Approaches.
How Much Wind Power Is Planned For The Western Approaches?
I asked Google AI, the title of this section and received this answer.
The UK has a target of 50 GW of offshore wind by 2030, with significant projects planned for the Celtic Sea (part of the Western Approaches), which is a key area for 5 GW of floating wind. Total UK offshore wind pipeline capacity exceeds 93 GW, with major developments in this region focusing on floating technology.
Key details regarding wind power in the Western Approaches (specifically the Celtic Sea) include:
Celtic Sea Developments: The area is a primary focus for floating wind projects, designed to capitalize on deep-water potential, with 5 GW of floating wind expected to be deployed across the UK by 2030.
Pipeline and Capacity: The total UK pipeline for offshore wind, which includes the Western Approaches, is 93 GW, and the government is aiming for 43-50 GW of installed offshore capacity by 2030.
Project Status: The region is expected to benefit from the Crown Estate’s leasing rounds aimed at accelerating floating wind, with 15.4 GW of new projects submitted across the UK in 2024.
Wales/South West England Context: Wales has 1.4 GW of projects in the pre-application stage, with some potential for developments off the South West coast.
For more detailed information on specific projects and their development status, you can visit the RenewableUK website and RenewableUK website.
It looks like about 20 GW of offshore wind could be installed in the Western Approaches.
I would expect, a lot of work will be generated in the Port Talbot area.
A Lot Of Steel Will Be Needed
Earlier in the weeek, the UK Government backed the steel industry in Port Talbot, with a press release entitled UK Steel Industry Backed By Major New Trade Measure And Strategy.
Port Talbot Is A Comprehensive, Well-Connected Site
This Google Map shows the site.
Note.
- The M4 running along the site.
- The South Wales Main Line running along the site, with Port Talbot Parkway serving the site.
- The harbour by the station.
- The Tata steelworks marked by the red arrow.
I hope the up to £64 million grant from the government is sufficient for Associated British Ports (ABP) to turn the harbour into a world-class floating wind facility and that the Treasury haven’t been too mean.
BW Ideol, ABP To Explore Serial Production Of Floating Wind Foundations At Port Talbot
I wrote a post with this name in December 2023, before the leases for the Celtic Sea windfarms had been awarded. As one has been awarded to EDf Renewables, BW Ideol seem to have made a good move.
BW Ideol have a web page, which describes their concrete floating wind foundations manufacturing line.
I hope South Wales has got enough concrete?
UK Continues Offshore Wind Expansion With 6 GW Leasing Round Planned For Early 2027
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
The Crown Estate has unveiled plans for the UK’s Offshore Wind Leasing Round 6 to be held in the first half of 2027, targeting the development of at least 6 GW of new capacity.
These three paragraphs add some details.
The upcoming leasing process will focus on areas primarily located in the northeast of England. The sites are expected to be suitable for fixed-bottom offshore wind projects and will be brought forward following market and stakeholder engagement, including the National Energy System Operator’s (NESO) strategic plans for energy and for electricity networks, which will inform the exact capacity of the upcoming leasing round and refine specific site details and locations.
The Crown Estate said on 26 March that it had begun a programme of market engagement ahead of the official launch of a new leasing round, and is seeking market views on commercial approaches to the leasing round “to understand the potential viability and market appetite.”
The UK seabed manager said that it had also identified other areas of seabed opportunity across the South West, Wales and other regions which may form the basis of subsequent leasing rounds through the Crown Estate’s new seabed management tool, the Marine Delivery Routemap, which is being used for the first time in Round 6.
In Renewable Power By 2030 In The UK, I calculated how much offshore wind could be commissioned up to 2030.
These were my results.
This gives these yearly totals, if I use pessimistic dates.
- 2025 – 1,235 MW
- 2026 – 4,807 MW
- 2027 – 5,350 MW
- 2028 – 4,998 MW
- 2029 – 9,631 MW
- 2030 – 15,263 MW
This adds up to a total of 58,897 MW.
But This Doesn’t Include Round 5 Or Round 6!
But the article on offshoreWIND.biz does, say this about Round 5.
The Crown Estate’s previous leasing round, Round 5, focused on floating offshore wind in the Celtic Sea, covering areas off South Wales and South West England and targeting up to 4.5 GW of capacity. The round awarded seabed rights to Equinor, Gwynt Glas, and Ocean Winds, with individual project development areas of up to 1.5 GW. Agreements for lease were recently signed for all three Round 5 sites.
The article also indicates that 6 GW can be expected from Round 6.
Which gives a total of 69,397 MW or 69.4 GW.
No wonder the UK Government can back the steel industry, with press releases like this UK Steel Industry Backed By Major New Trade Measure And Strategy.
Lots of renewable energy, is the new rich!
WSMR Plans Alstom-Built Bi-Mode Sets If Open Access Bid Approved
The title of this post, is the same as that of this article on Rail magazine.
This is the sub-heading.
Wrexham, Shropshire & Midlands Railway (WSMR) has said it will invest in new Alstom battery-electric bi-mode trains if its open access application is successful.
These three paragraphs add some more details.
In December the Alstom-backed operation resubmitted its application to run between the North Wales city and London Euston via Shrewsbury and Walsall after its initial bid was rejected by the Office of Rail and Road (ORR) last year.
In a letter to the regulator and Network Rail, Mobilisation Director Darren Horley said: “Should our application be successful, WSMR will work alongside its parent company, Alstom, and will commit to invest in a new bi-mode battery-electric fleet based on the Adessia platform – Alstom’s new generation passenger train designed specifically for the UK market.
“Initial discussions regarding the procurement of a small new fleet have already commenced with Alstom and a financier.”
The Adessia will be a high speed version, with a maximum speed of 125 mph or 200 kph.
I have some thoughts.
How Much Of The Route Is Without Electrification?
In Alstom Plans To Operate Its Own Passenger Train Service In The UK For The First Time, I gave these distances of the sections of the route.
- Euston and Nuneaton – 96.7 miles – electrified
- Nuneaton and Walsall – 26.7 miles – electrified
- Walsall and Wolverhampton – 6.7 miles – electrified
- Wolverhampton and Shrewsbury – 29.7 miles
- Shrewsbury and Wrexham General – 30.3 miles
That looks like there are sixty miles in each direction without electrification.
Either the trains would have a battery range of 120 miles or a battery range of over 60 miles with charging at Wrexham General station, which is shown in these pictures.
Note.
- Wrexham General station has four platforms. Two are a pair of long through platforms and there are also a separate long and a short through platform.
- The station is step-free.
- The last four pictures are Platform 4.
This OpenRailwayMap shows the platform layout at Wrexham General station.
Note.
- The blue arrow is between the two through Platforms 1 and 2.
- Platform 3 is the platform in the middle.
- Platform 4 is the platform on the left.
An overhead charging rail could be used on Platforms 3 and/or 4, as has been used at Caerphilly station.

The overhead charging rail could also charge other Wrexham General services.
Prospective Routes
I would expect that there would be a need for such a train on the following UK routes.
- CrossCountry – Class 221 train replacement.
- East-West Rail – New fleet.
- Southeastern – London and Hastings.
- ScotRail – Inter7City replacement.
- South Western Railway – Class 158 and Class 159 train replacement.
- Transport for Wales – Some diesel services.
There would be probably be other services too!
Will The Service Call At Willenhall, Darlaston And Walsall?
This OpenRailwayMap shows the three stations.

Note.
- Willenhall station is in the North-West corner of the map.
- Darlaston station is marked by the blue arrow.
- Walsall station is in the North-East corner of the map.
- Tame Valley Parkway station is in the South-East corner of the map.
- It might also be a good idea to call at the Parkway station.
- Red tracks are electrified.
- To call at all four stations will need a reverse at Walsall.
There may be some thinking to do, on the best calling pattern in Walsall.
