More than 1,250 rooms in private homes have been registered so far, alongside accommodation in B&Bs, guest houses, hotels and static caravans.
The flood of offers follows ads in the local press offering homeowners the chance to cash-in on the local construction boom.
An application for the main site construction will be made to the Infrastructure Planning Commission later this year.
If successful, around 5,600 workers would be employed during peak construction of the new power station.
EDF Energy has set-up a dedicated Accommodation Office to help house the army of builders.
Dawn Hartley, Accommodation Office manager said: “It’s great that so many local people have come forward with accommodation they wish to let.
“We’re particularly pleased to see those offering rooms which have not previously been let as this increases the total accommodation available and will be financially beneficial to local residents.”
EDF Energy is also proposing campus accommodation for workers at three locations.
