Stena Line has announced that an outline planning application has now been submitted to Isle of Anglesey County Council to redevelop the former Anglesey Aluminium site, now known as Prosperity Parc, into a new technology park.
The submission of a planning application follows a public consultation held between December 2024 and January 2025, where residents were invited to have their say on the early plans to create approximately 200,000 sqm of industrial and office development as part of a low-carbon campus.
The proposals include space for technology and data centre buildings and a Battery Energy Storage System (BESS) scheme, as well as over 15,000 sq ft of office space. The development is expected to generate up to 1,200 new jobs on the island and support UK investment in data and renewable energy.
The site forms a key part of the vision of Anglesey Freeport, sitting within the Anglesey Prosperity Zone, a now-designated tax site following approval from the UK and Welsh Governments. Supported by Anglesey Freeport and its partnerships, the project would enable the delivery of training across all skill ranges, providing clear development paths for local people to benefit from the new jobs created.
Stena Line’s economic forecasts estimate that, when fully operational, Prosperity Parc has the potential to generate up to £578 million GVA, equivalent to increasing the future size of the Anglesey economy by a third.
Ian Davies, Head of UK Port Authorities at Stena Line, said:
“We are pleased to announce the submission of our planning application for Prosperity Parc and would like to thank all those who took part in our public consultation. It is clear there is great anticipation locally around bringing new investment and jobs to the Island, and it is exciting to have taken this step forward to deliver for the people of Ynys Môn.”
The Anglesey Freeport project is being jointly developed as a public/private partnership between the Isle of Anglesey County Council and Stena Line.
Anglesey’s Chief Executive, Dylan J. Williams, said:
“The progression of Prosperity Parc from site clearance to new investment and development would be a real tangible step in realising the vision of Anglesey Freeport whilst creating significant jobs and training opportunities for local people. The application will now be progressed in full accordance with the statutory planning process.”
The application can be found by using the reference number OP/2025/2 on the Isle of Anglesey County Council’s planning portal.
