Work starts on £14.7m Port of Mostyn upgrade backed by North Wales Growth Deal
Ambition North Wales says substantial site clearance has been completed at the port's Marsh Row site, with £4m of Growth Deal money helping to refurbish 172,000 sq ft of industrial buildings for future business occupiers.
Work has started on a £14.7m upgrade of the Port of Mostyn in North Wales, with £4m of the cost coming from the North Wales Growth Deal and the port funding the balance, Ambition North Wales announced on 9 November.
The regional body said the improvements are designed to let the port handle the next generation of larger offshore wind components and to accommodate businesses working across the renewable energy supply chain.
Substantial site clearance has been completed at the port's Marsh Row site, according to Ambition North Wales. The next stage is to reconnect mains services and refurbish key buildings for future business occupiers.
Jim O'Toole, Managing Director of The Port of Mostyn, said: "This investment supports our strategy to futureproof the port and expand our role in the renewables sector. The improved facilities will increase our capacity to meet the needs of growing low carbon industries".
The scheme
Ambition North Wales said it had previously approved the £4m allocation from the Growth Deal as part of the £14.7m package. The project is to refurbish 172,000 sq ft of industrial buildings by 2030 and bring 45 acres of employment land back into productive use by 2032.
The body expects the project to support 300 net additional full-time-equivalent (FTE) jobs, split as follows:
| Job type | FTE jobs |
|---|---|
| Direct | 213 |
| Indirect | 87 |
Cllr Mark Pritchard, Chair of Ambition North Wales, said: "This decision marks a positive step for the regional economy. Strengthening the Port of Mostyn's capabilities will help create quality employment opportunities, support a growing clean energy sector".
Adam Price, Cabinet Minister for Enterprise, Connectivity and Energy, said the investment would help strengthen North Wales's position in the renewable energy sector and create opportunities for businesses and employment.
Offshore wind demand
Wales Office Minister Anna McMorrin described the port as a vital link in the supply chain for new offshore wind sites such as Awel y Môr, which she said had recently won a UK Government contract and would see up to 50 turbines built off the North Wales coast.
According to the Wales Office, Awel y Môr was among the projects to win a contract in the Contracts for Difference auction on 14 January 2026. The Erebus project in the Celtic Sea off Pembrokeshire was also successful in the same auction, it said.
Developer RWE confirms on its project page that Awel y Môr received a Contract for Difference in January 2026, but says the final turbine count has not been fixed. The maximum tip height would be up to 332m if there are up to 34 turbines, or 250m if there are up to 50, and the precise number and dimensions will be decided later in the development process, RWE said.
The Growth Deal
The North Wales Growth Deal was signed in December 2020 and secures £120m from the Welsh Government and £120m from the UK Government, according to Ambition North Wales. The body says the agreement is intended to generate total investment of more than £1bn for the region and create 4,200 new jobs.
Government funding for the deal is received annually over 15 years, Ambition North Wales said.
The Port of Mostyn project's refurbished industrial buildings are due to be complete by 2030, with the 45 acres of employment land back in use by 2032.
