In November 2009 the government announced that Sizewell, amongst other sites, would be a suitable location for a new nuclear power station.
EDF Energy is bringing forward an application to construct and operate Sizewell C. Details of the proposals are available on EDF Energy’s Sizewell C pages.
In 2011 the National Policy Statements for Energy Infrastructure were approved. These contain the policies by which applications for major energy projects are judged, and as such, are relevant to the Sizewell proposals.
The Planning Inspectorate will determine the application, not the local councils.
However Suffolk County Council and East Suffolk Council are statutory consultees and will evaluate, challenge and comment upon the proposals for a new nuclear power station to get the best possible outcomes for the people of Suffolk.
