The owner of the former Shell oil depot on Anglesey is developing fresh plans for the giant site.
The 200 acre site at Rhosgoch was one of three sites in north Anglesey that would have housed up to 10,000 workers during the construction project.
An option agreement was signed between Horizon Nuclear Power and Conygar Investment Company in 2017 with hopes the site could be transformed into a holiday park once the plant was built.
But in January parent company Hitachi announced the Wylfa Newydd project was being put on hold after - and the option agreement was later dropped.
Now Conygar, which is also looking to develop a marina in Holyhead, says it is considering its options for the site - with renewables now the focus.
They have not stated what type of renewables and when asked if this could include wind turbines on the site, they said "all options" were being looked at.
A spokesman said: "This is a large site, this is an important site and we are considering our options.
"We are looking at renewables and would consider all options."

The site had served as a storage station for crude oil from a receiving shore station at the Port of Amlwch before transfer via a cross country underground pipeline to the Company’s oil refinery at Stanlow, Ellesmere Port.
In 2000 it was agreed to sell the former depot to Burlington Resources for £5.5 million in the first step towards having a gas-fired power station built on the island.
Those plans did not come to fruition.
There have also been calls for a 'Center Parcs' style holiday park development on the land.
