Thousands of jobs could be created by making the port of Holyhead into a freeport, its owners have claimed.
Shipping company Stena Line said it was working with companies that were interested in building factories on Anglesey, if freeport status was granted.
Holyhead is expected to be one of five Welsh bidders for freeport status.
The UK and Welsh governments will make a joint decision on where the first one will be
Stena Line has already bought the former Anglesey Aluminium site so companies can set up factories within the freeport zone if the status is awarded.
It said it was in discussions with Rolls Royce and Bechtel, which are interested in making components for small nuclear reactors.
Ian Hampton, executive director of Stena Line Ports said: "We can bring businesses that wouldn't ordinarily come to Holyhead, they can take advantage of what a freeport brings, but also create new jobs, and create economic growth for the whole of north Wales, and for the UK."
He added that it had the potential for ?1bn of growth and up to 13,000 new jobs.
