£64 million for Port Talbot offshore wind hub in the Celtic Sea
Summary
Government grants £64 million to Associated British Ports for design and engineering work to develop Port Talbot as a floating offshore wind port. The port would support 4.5 GW of Celtic Sea floating wind projects following Crown Estate seabed leasing. Funding is subject to Subsidy Advice Unit approval and final government sign-off.
Why it matters
This backs floating wind infrastructure rather than generation itself — a necessary but not sufficient condition for Celtic Sea development. The real constraint remains grid connections and CfD allocation rounds, not port capacity.

What this is about
The government has awarded £64 million to Associated British Ports for design and engineering work to develop Port Talbot as a floating offshore wind port hub for the Celtic Sea. This represents infrastructure investment ahead of generation assets, targeting the 4.5 GW of Celtic Sea floating wind projects that secured seabed leases from The Crown Estate in 2023.
The funding addresses a genuine infrastructure gap. Floating offshore wind requires specialist port facilities for turbine assembly and deployment—different from fixed-bottom wind infrastructure. Port Talbot's deep-water access and industrial legacy make it a logical choice, but the business case depends on certainty around Celtic Sea project development timelines and grid connection capacity.
Key points
Funding structure: The £64 million covers design and engineering work only, not construction. ABP must secure additional private investment for the estimated £500 million total project cost. Terms are agreed but funding remains subject to Subsidy Advice Unit approval and final government sign-off.
Capacity target: The port would support 4.5 GW of floating wind capacity—the full allocation from The Crown Estate's Celtic Sea leasing round. This translates to roughly 6.5 million homes worth of generation capacity at typical load factors.
Industrial context: This sits within broader Port Talbot regeneration following Tata Steel's transition to electric arc furnace steelmaking (£500 million government support) and the Celtic Freeport designation. The government frames this as industrial diversification rather than replacement.
Technology focus: Floating offshore wind operates in waters 60+ metres deep where fixed foundations become uneconomical. The Celtic Sea offers water depths of 60-200 metres with consistent wind resources, making it suitable for floating platforms that can access higher wind speeds than nearshore fixed turbines.
Jobs claims: ABP estimates "thousands" of jobs during construction and operation. Government claims up to 5,000 jobs total, though this likely includes indirect and induced employment across the supply chain rather than direct port employment.
What happens next
The immediate dependency is Subsidy Advice Unit assessment of the £64 million grant under subsidy control rules. This process typically takes 3-6 months and examines market distortion risks and value for money.
Assuming approval, ABP begins detailed design work for port infrastructure modifications. The existing port requires significant upgrades: deeper berths, heavy-lift cranes, and assembly areas for floating platforms that can exceed 200 metres in length.
The critical uncertainty lies beyond port development. Celtic Sea projects face two major hurdles: grid connections and Contract for Difference allocation. NESO's transmission planning for Celtic Sea connections remains at early stages, with no confirmed delivery dates for the required offshore transmission infrastructure. Projects cannot achieve financial close without both CfD contracts and grid connection agreements.
The next CfD allocation round (AR6) is expected in 2024 but floating wind strike prices remain significantly above fixed-bottom equivalents. Without cost reduction or technology-specific support, Celtic Sea projects may struggle to secure contracts at administratively acceptable prices.
Planning consent represents another bottleneck. The 4.5 GW pipeline requires Development Consent Orders through the Planning Inspectorate, typically taking 18-24 months. Projects are at varying stages of pre-application work.
Port Talbot's commercial viability depends on construction timing alignment across multiple projects. If Celtic Sea development phases stretch over 10+ years, the port investment may not generate sufficient throughput to justify the infrastructure cost. ABP needs reasonable certainty that multiple projects will reach construction phase within a concentrated timeframe.
The government's broader floating wind strategy includes technology support through the Floating Offshore Wind Manufacturing Investment Scheme and R&D funding. However, these programs support component manufacturing rather than project-level deployment.
Regional competition adds complexity. Other Celtic Sea ports—including Milford Haven and potentially Irish facilities—are developing similar capabilities. The market may not support multiple specialist floating wind ports unless the pipeline expands significantly beyond current Crown Estate allocations.
The 2030 timeline for initial Celtic Sea project commissioning appears optimistic given current development timelines. More realistic scenarios suggest 2032-2035 for first commercial operations, which pushes peak port utilization further into the 2030s.
Success ultimately depends on factors beyond ABP's control: transmission infrastructure delivery, CfD allocation outcomes, and overall floating wind cost competitiveness. The £64 million represents a necessary but not sufficient investment for Celtic Sea floating wind development.

Up to £64 million to back Port Talbot’s development as the first port in the Celtic Sea specifically developed to support floating offshore wind – a major step in delivering the clean power mission The new port will help unlock at least 4.5 GW of floating offshore wind in the Celtic Sea – helping deliver clean, homegrown electricity, protect households from volatile fossil fuel markets and create up to 5,000 new jobs Builds upon work from the UK government to support the steel industry in Port Talbot, and to allocate of all the £122 million funding to providing training for Tata Steel workers and businesses to regenerate the town Port Talbot will be the forefront of a pioneering new clean energy industry, backing thousands of good jobs and driving growth across South Wales, thanks to a £64 million grant from the UK government. The funding will enable Associated British Ports ( ABP ) to complete the essential design and engineering work needed to build one of the first floating offshore wind ports in the UK at Port Talbot. The Celtic Sea offers some of the best conditions for floating offshore wind in Europe. Unlike traditional offshore wind farms, floating turbines are based in deeper waters, where they can harness stronger and more consistent wind speeds. The new port will unlock an initial 4.5 GW of floating offshore wind projects in the Celtic Sea - enough to power 6.5 million homes - following last year’s successful seabed leasing round by The Crown Estate. ABP expect that, once completed, the new port will support thousands of jobs and unlock over £500 million in investment for Port Talbot. The conflict in the Middle East has once again exposed that families and businesses will continue to pay the price if the UK is dependent on fossil fuel markets that we do not control. The only way to take back control of Britain’s energy and bring down bills for good is with clean, homegrown power. Funding for Port Talbot is another step in learning the right lessons from the conflict, while bringing jobs and the industries of the future to South Wales. Energy Secretary Ed Miliband said: From floating offshore wind in Port Talbot to a new generation of small modular reactors at Wylfa – this government is putting Wales at the heart of our clean energy superpower mission. With its deep waters and strong winds we are supporting to Wales to storm ahead in floating offshore wind – a pioneering industry that will support thousands of good jobs, drive growth across the country and unlock the next generation of clean, homegrown power. Henrik L. Pedersen, Chief Executive Officer of ABP , said: Today’s visit marks real progress on the shared ambition between ABP and the UK government to secure the infrastructure needed to deliver floating offshore wind at scale. Agreeing terms on government support is a critical step towards further ABP investment at Port Talbot and establishing the port as a cornerstone of the Celtic Sea floating offshore wind industry. This development would drive industrial regeneration, support thousands of skilled jobs and ensure Wales and the UK captures the full economic benefit of this emerging sector. Secretary of State for Wales Jo Stevens said: This is a significant moment for Port Talbot and a major step forward for the growing clean energy industry in Wales. This investment will further cement Port Talbot as a hub of the industries of the future, and heralds the next chapter of jobs, and investment to the area. The UK government has backed steelworkers and the community in Port Talbot with £100 million in direct support, and £500 million for the construction of a new Electric Arc Furnace ensuring that the town will manufacture clean steel into the future. Thanks to our investment, the work of trade unions and local businesses, and the dedication and spirit of local people - Port Talbot and the whole region have a very bright future. Grant terms have been agreed with ABP and the funding will be subject to the outcome of the mandatory Subsidy Advice Unit referral and final government approvals. This funding is the latest decisive action by the UK government to secure Port Talbot’s industrial future, including supporting Tata Steel with £500 million to deliver a state-of-the-art Electric Arc Furnace, ensuring Port Talbot will remain a steel-producing town. It also comes a week after the launch of the government’s Steel Strategy which, backed by up to £2.5 billion, will help it meet its target of supplying 50% of domestic demand for steel and secure the industry’s role in supporting vital UK sectors such as infrastructure, defence, and clean energy. Alongside this, the UK Government allocated all £122 million of The UK government Port Talbot Transition Board funding to support thousands of workers, businesses and communities affected by the transition at Tata Steel, helping to regenerate the town and support new economic opportunities. As well as securing the future of steelmaking the UK government has also made the Port Talbot the home of the Celtic Freeport which will bring thousands of new jobs. Clean steelmaking, the development of the Celtic Freeport and the expansion of floating offshore wind mean Port Talbot is firmly at the heart of South Wales’s growing clean energy economy, supporting thousands of new, high-quality jobs and helping deliver Britain’s clean power mission. Note for editors So far, Transition Board funding has delivered: financial support for the creation of 85 new businesses, through equipment grants from the Start-Up Fund grants to 59 companies in Tata Steel UK’s supply chain through the Supply Chain Transition Fund support for 141 local businesses through the Resilience and Business Growth Funds thousands of training courses for individuals affected by the Tata Steel transition As well as securing the future of steelmaking the UK government has also made the Port Talbot the home of the Celtic Freeport which will bring thousands of new jobs. Clean steelmaking, the development of the Celtic Freeport and the expansion of floating offshore wind mean Port Talbot is firmly at the heart of South Wales’s growing clean energy economy, supporting thousands of new, high-quality jobs and helping deliver Britain’s clean power mission.
