Ocean Winds Enters Lease Agreement With Crown Estate For 1.5 GW Celtic Sea Floating Wind Project
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
Ocean Winds has entered into an agreement for lease with the Crown Estate for a 1.5 GW floating offshore wind project, for which the developer secured a site in the Round 5 seabed auction last year.
These two paragraphs add detail to the story.
Offshore Wind Leasing Round 5, the UK’s first dedicated floating wind seabed leasing round, was launched in February 2024, offering three areas. In June 2025, the Crown Estate announced Equinor and Gwynt Glas, a joint venture between EDF and ESB, as preferred developers for two project sites and said it was working to ensure the delivery of the full potential capacity of Round 5, which is up to 4.5 GW.
Equinor and Gwynt Glas entered into lease agreements for their floating wind projects in October 2025 and, the following month, the Crown Estate said Ocean Winds had secured the third floating offshore wind site in the Celtic Sea.
This map shows the three wind farms, that make up the Glynt Glas wind farm.
Note.
- It is expected to be built from and connect to the grid at Port Talbot in South Wales.
- The three sites are expected to be commissioned by the early-to-mid 2030s.
- The elongated white dot to the East of the wind farms would appear to be Lundy Island.
- The large bay to the North of Lundy is Carmarthen Bay with Caldey Island at its West end and Llanelli on its East.
- The Gower separates Swansea Bay from Carmarthen Bay.
This Google Map shows the Bristol Channel from the wind farms in the West to Cardiff and Hinkley Point.
Note.
- Along the North coast of the Bristol Channel, working from West to East, my 78-year-old eyes can pick out Milford Haven, Pembroke, Caldey Island, Tenby, Llanelli, Swansea, Port Talbot, Porthcawl, BridgendCaerphilly, Cardiff and Newport.
- Coming back along the South Coast, I can see Weston-super-Mare, Hinkley Point C and the tip of Lundy Island in line with Tenby.
- The three sections of Glynt Glas will each generate 1.5 GW, making a total of 4.5 GW.
- Hinkley Point C when completed, will be a 3.26 GW nuclear power station.
- There is also a 2.2 GW gas-fired power station at Pembroke.
Nearly 8 GW of renewable electricity should be enough to convert Port Talbot steelworks to the manufacture of green steel.
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.
