Wylfa Power Station

Asked by Andrew BowieConservativeDepartment for Energy Security and Net ZeroTabled Answered 1 July 2025UIN 61555

The question

To ask the Secretary of State for Energy Security and Net Zero, if he will publish the previous Government’s cost impact assessment for building a gigawatt scale nuclear plant at Wylfa.

Answered by Michael Shanks

Great British Energy–Nuclear acquired the Wylfa site last year and we will set out our plans in due course. No decision has yet been taken on whether to pursue a future large-scale project beyond Sizewell C, but all nuclear projects are subject to a detailed value for money assessment, including cost.
