The construction programme is scheduled to reach its peak in 2017 when 6,000 workers will be on site.
The Isle of Anglesey County Council has decided to house builders in a mix of purpose built, rented and tourist accommodation if the new nuclear power station gets the go-ahead.
The workers’ village will hold around 2,000 people with the majority off-site.
Anglesey Energy Island Programme Director, Sasha Wynn Davies, said: “To put the scale of the proposed new nuclear build at Wylfa into perspective, peak construction would occur in around 2017 resulting in approximately 6,000 construction workers being on site.
“This option was identified as the preferred position as it supports a number of cross cutting themes; it ensures that the legacy is sustainable, after the construction period ends, it encourages and controls an appropriate development mix, it increases accommodation choice for workers and residents and it is also flexible enough to respond to market conditions and demands.”
