Economy Minister Ken Skates says there is US interest in reviving plans for a nuclear plant on Anglesey - with American energy giant Westinghouse "believed" to be involved.
Japanese multi-national Hitachi this month announced they were pulling out of funding the £16bn Wylfa Newydd development.
But hopes remain that the project has not been killed off and BEIS Secretary of State Alok Sharma will today announce if the Development Consent Order (DCO) for the site has been successful.
Now Welsh Government minister Mr Skates says he understands the US are keen to be involved in the site, described as the "best in the Uk" for new nuclear.
He told Business Live: "In spite of Hitachi’s deeply disappointing announcement I’m still very optimistic for the Wylfa site. It’s the very best site in the UK, arguably Europe.
"We’re engaging with UK Government in terms of other interested parties. We are aware, with regard to potential other investors that key allies are interested in Wylfa, the United States, Westinghouse, they are interested we believe.
"We’ll work with our partners to explore every single option there is to guarantee that all energy that is required to secure an alternative funder and potentially technology provider will be explored.
"There are huge opportunities with nuclear right across North Wales."
Westinghouse Electric Company has not commented.
The company had previously been involved in a bidding war for the Wylfa site, ultimately losing out to Hitachi in 2012.
Its AP1000 nuclear power plant design has successfully completed review by UK regulators.
The reactors were due to be used by NuGen, the UK joint venture between Japan's Toshiba and France's Engie, at Moorside, in West Cumbria. But in November 2018, Toshiba announced it was withdrawing from the new-build project.
US president Donald Trump has previously stated he would not want the Wylfa development sold to Chinese investors.
The department of Business, Energy and Industrial Strategy(BEIS) has been asked to comment.
