Ocean Winds Secures Third Celtic Sea Floating Wind Site

The title of this post, is the same as that of this article on offshoreWIND.biz.

This is the sub-heading.

Ocean Winds has secured the third floating offshore wind site in the Celtic Sea, offered through the Crown Estate’s Round 5 auction earlier this year. The developer is joining Equinor and the Gwynt Glas joint venture, which were awarded rights for two of the three sites offered in Round 5 in June.

This paragraph outlines Ocean Winds’s deal.

On 19 November, the Crown Estate said that Ocean Winds was set to be awarded the rights for a third floating offshore wind site in the Celtic Sea.

There would now appear to be three Celtic Winds deals for wind farms.

  • Gwynt Glas – 1.5 GW
  • Ocean Winds – 1.5 GW
  • Equinor – 1.5 GW

Note.

  1. 4.5 GW will be able to power a good proportion of South Wales and  the South-West peninsular.
  2. In Gwynt Glas And South Wales Ports Combine Strength In Preparation For Multi-Billion Floating Wind Industry, I talk about partnerships between the wind farms and the ports.
  3. If you sign up for a  large wind farm from the Crown Estate, do you get to have afternoon tea with Charles and Camilla in the garden at Highgrove or even Buckingham Palace?

This map of the wind farms is available from download from this page on the Crown Estate web site.

Note.

  1. Gwynt Glas is in green.
  2. Ocean Winds is in blue.
  3. Equinor is in mauve.
  4. The white dot to the East of the wind farms is Lundy Island.

This triple wind farm is certainly well-placed to supply power to Cornwall, Devon and South Wales.

Gwynt Glas And South Wales Ports Combine Strength In Preparation For Multi-Billion Floating Wind Industry

The title of this post, is the same as that of this news item from the Gwynt Glas wind farm.

The news item starts with a spectacular image of a port, that is assembling floating wind turbines and these three paragraphs.

Gwynt Glas Offshore Wind Farm has signed a Memorandum of Understanding (MoU) with the UK’s largest port operator, Associated British Ports, and Wales’ largest energy port, the Port of Milford Haven, to ready the ports for the future needs of floating offshore wind in the Celtic Sea.

Gwynt Glas is a joint venture partnership between EDF Renewables UK and DP Energy. The proposed floating offshore wind farm would generate 1GW of low carbon green energy in the Celtic Sea.

Under the MoU, information and industry knowledge will be shared to investigate the potential opportunities for manufacture, assembly, load-out and servicing for the Gwynt Glas project from the key South Wales Ports of Port Talbot and Milford Haven. This collaborative approach demonstrates a major commitment to supporting economic growth, investment and maximising social value in the region.

Equinor, EDF-ESB Joint Venture Secure 1.5 GW Sites In UK Floating Wind Leasing Round

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 selected Equinor and Gwynt Glas, a joint venture between EDF Renewables UK and ESB, as preferred bidders in the seabed leasing round for floating wind projects in the Celtic Sea.

These two paragraphs give more details.

Selected on 12 June, each of the two developers was awarded 1.5 GW of capacity in their respective project development area (PDA) for an annual option fee of GBP 350/MW (approximately EUR 410/MW).

The Crown Estate launched the floating wind leasing round (Offshore Wind Leasing Round 5) in February 2024, offering three areas off the coasts of Wales and South West England for a total of up to 4.5 GW of installed capacity.

Note.

  1. It looks like the Crown Estate are working to get a contract for the third site.
  2. The ports of Bristol and Port Talbot could be handling the assembly of the floating turbines.
  3. The Crown Estate has also established a new strategic approach with the National Energy System Operator (NESO).

Given the problems some wind and solar farms have had to get connected, the Crown Estate’s link up with NESO could be attractive to developers?

Conclusion

This looks a good bit of business by the Crown Estate in the Celtic Sea.

Did they get NESO to be helpful, by asking senior people for tea with Charles and Camilla at Highgrove?

The Crown Estate Announces Areas Of Search To Support Growth Of Floating Wind In The Celtic Sea

The title of this post, is the same as that of this press release from the Crown Estate.

This is the first paragraph.

In a major step forward in supporting the UK’s net zero ambitions, The Crown Estate has today identified five broad ‘Areas of Search’ for the development of floating offshore wind in the Celtic Sea – a region rich in natural resources, including world-class wind resource that can be developed with floating turbines. This marks a significant milestone and provides the foundation on which to build greater capacity in the future, helping the UK to achieve its renewable energy targets and drive economic development.

Points in the press release include.

  • Five areas with good wind power potential have been chosen.
  • A competitive tender, is to be launched in mid-2023.
  • It is intended that these areas will deliver 4GW of floating offshore wind power by 2035.

This map shows the areas.

I have a few thoughts.

What About The Other Wind Farms Already Announced In the Celtic Sea?

In DP Energy And Offshore Wind Farms In Ireland, I said this.

They are also developing the Gwynt Glas offshore wind farm in the UK sector of the Celtic Sea.

  • In January 2022, EDF Renewables and DP Energy announced a Joint Venture partnership to combine their knowledge and
    expertise, in order to participate in the leasing round to secure seabed rights to develop up to 1GW of FLOW in the Celtic Sea.
  • The wind farm is located between Pembroke and Cornwall.

The addition of Gwynt Glas will increase the total of floating offshore wind in the UK section of the Celtic Sea.

  • Blue Gem Wind – Erebus – 100 MW Demonstration project  – 27 miles offshore
  • Blue Gem Wind – Valorus – 300 MW Early-Commercial project – 31 miles offshore
  • Falck Renewables and BlueFloat Energy – Petroc – 300 MW project – 37 miles offshore
  • Falck Renewables and BlueFloat Energy – Llywelyn – 300 MW project – 40 miles offshore
  • Llŷr Wind – 100 MW Project – 25 miles offshore
  • Llŷr Wind – 100 MW Project – 25 miles offshore
  • Gwynt Glas – 1000 MW Project – 50 miles offshore

This makes a total of 2.2 GW, with investors from several countries.

It does seem that the Celtic Sea is becoming the next area of offshore wind around the British Isles to be developed.

So what about these seven wind farms?

Erebus and Valorus

Is Blue Gem’s philosophy to develop and prove the technology and put in big bid for around a GW?

Gwynt Glas

The Gwynt Glas web site says this.

The Crown Estate announced in March 2021 that it intends to run a competitive leasing round to award seabed rights to developers for floating offshore wind (FLOW) projects in the Celtic Sea, targeting an overall regional capacity of 4GW.

In January 2022, EDF Renewables and DP Energy announced a Joint Venture partnership to combine their knowledge and expertise, in order to participate in the leasing round to secure seabed rights to develop up to 1GW of FLOW in the Celtic Sea.

The partnership project is called Gwynt Glas, Welsh for Blue Wind, in recognition of its Celtic roots.

Our proposed floating offshore wind project could provide power for approximately 920,000 homes.

It looks like they’re throwing their hat into the ring for 1 GW.

Llŷr Wind

The Llŷr Wind web site says this.

Combined, the two 100MW projects will generate enough renewable electricity to power around 250,000 homes. If successful, we will be able to offer highly cost-effective, floating offshore wind farms to the rest of the world by 2030.

By unlocking new, higher energy capacities from deeper waters, further offshore, the Llŷr projects have huge implications for UK energy consumers. Not only will they help the UK meet its target for net zero emissions, but they will create new opportunities for regional manufacturing and supply chains in Wales and Southwest England as global demand for floating, offshore, wind rises.

It looks to me that this project hasn’t been fully defined yet. Perhaps, this will happen after a successful bid.

Llywelyn

The Llywelyn web site says this.

Llywelyn wind farm is located in Welsh waters in the Celtic Sea, 40 miles off the coast of Pembrokeshire.
Llywelyn’s location has been selected following an extensive feasibility study and rigorous site assessment process. Our assessment has included reviews of protected areas, environmental impacts, cable routing, existing infrastructure, marine traffic, and fishing activity.

We have signed an agreement with National Grid, securing a 300MW grid connection in Pembrokeshire. The system operator is exploring upgrades to the existing site to facilitate the connection. These developments will enable the Llywelyn offshore wind project to quickly enter the planning system.

Have they already said go?

Petroc

The Petroc web site says this.

Petroc’s location has been selected following an extensive feasibility study and rigorous site assessment process. Our assessment has included reviews of protected areas, environmental impacts, cable routing, existing infrastructure, marine traffic, and fishing activity.

We have signed an agreement with National Grid, securing a 300MW grid connection in North Devon. The system operator is exploring upgrades to the existing site to facilitate the connection. These developments will enable the Petroc offshore wind project to quickly enter the planning system.

Have they already said go?

These companies are certainly setting themselves up for bidding or have already got a smaller deal.

How Much Wind Power Can Be Developed In The Celtic Sea?

This article on the Engineer is entitled Unlocking The Renewables Potential Of The Celtic Sea.

The article starts with these two paragraphs.

Over the last decade, the UK has become a global leader in renewable marine energy, tapping into the vast resources its coastal geography offers. Offshore wind, in particular, has flourished, with gigawatt-scale projects being deployed off the east coast of England and Scotland, at Hornsea, Dogger Bank and Moray.

However, looking at a map of existing and proposed wind farms, what’s perhaps most striking is the complete absence of projects in the southwest of Britain, off the rugged shores of Wales, Devon and Cornwall, shaped by the fierce North Atlantic. The Celtic Sea – which extends south off Wales and Ireland down past Cornwall and Brittany to the edge of the continental shelf – is estimated to have around 50GW of wind generating capacity alone. What’s more, it also delivers some of the highest tidal ranges in the world, alongside some of the best waters in Europe for generating wave energy. In a country blessed with renewable resources, the Celtic Sea may well be its biggest prize.

I’ll go along with what this article says and accept that 50 GW of wind capacity could be installed in the Celtic Sea.

As I write this article at around nine o’clock, the UK is generating almost exactly 30 GW of electricity, which gives an idea of how large electricity production in the Celtic Sea could be.

Conclusion

It will be interesting to see how this first round of leasing in the Celtic Sea develops.

DP Energy has given the name Latitude 52 to the area it is exploring for a potential future offshore wind farm off the coast of Counties Wicklow and Wexford.

It appears to be another 1 GW project.

Shelmalere Offshore Wind Farm

Located off the East Coast of Ireland, the Shelmalere Offshore Windfarm project will utilise fixed bottom wind turbines and upon completion, will have the potential capacity of up to 1 GW.

Note.

  1. These wind farms are being developed in a partnership with Spanish Energy company; Iberdrola.
  2. Each is a one GW offshore wind farm.

They are also developing the Gwynt Glas offshore wind farm in the UK sector of the Celtic Sea.

  • In January 2022, EDF Renewables and DP Energy announced a Joint Venture partnership to combine their knowledge and
    expertise, in order to participate in the leasing round to secure seabed rights to develop up to 1GW of FLOW in the Celtic Sea.
  • The wind farm is located between Pembroke and Cornwall.

The addition of Gwynt Glas will increase the total of floating offshore wind in the UK section of the Celtic Sea.

  • Llŷr Wind – 100 MW Project – 25 miles offshore
  • Gwynt Glas – 1000 MW Project – 50 miles offshore

This makes a total of 2.2 GW, with investors from several countries.

It does seem that the Celtic Sea is becoming the next area of offshore wind around the British Isles to be developed.

Interconnectors

Interconnectors are to be built to connect Ireland, UK and France.

The Celtic Interconnector is being built between County Cork in Ireland and the North West Coast of France.

Greenlink is being built between County Wexford in Ireland and Pembroke in Wales.

Conclusion

Are the British, Irish and French governments, planning to build a large wind power resource in the Celtic Sea?
