A £14.7m upgrade at Port of Mostyn is now underway, helping the North Wales site handle larger offshore wind components and other energy projects planned for the Celtic Sea.
The package includes £4m from the North Wales Growth Deal, administered by Ambition North Wales. It is intended to support businesses across the renewable energy supply chain and strengthen the port’s role in low-carbon industries.
More space for future energy projects
The project is expected to support 300 net additional full-time jobs: 213 directly and 87 indirectly. It will also refurbish 172,000 square feet of industrial buildings by 2030 and return 45 acres of employment land to productive use by 2032.
Site clearance at Marsh Road has been completed. Work will now focus on reconnecting mains services and refurbishing key buildings for future business occupiers.
Port of Mostyn is described as a vital link in the supply chain for new offshore wind developments, including Awel y Môr, which is planned for waters around 10km off the North Wales coast and could feature up to 50 turbines.
Why it matters for Britain
The investment gives North Wales more capacity to support offshore wind and related businesses. Alongside the expected 300 jobs, the refurbished buildings and employment land could create further opportunities for companies working in the regional renewable energy supply chain.
