Hinkley Point C

EDF Energy’s 'sister' project to Sizewell C is Hinkley Point C in Somerset. The Development Consent Order for this was granted in March 2013. The Secretary of State’s decision letter and the panel report to the Secretary of State may be of interest. There is a great deal of other information on the process of the Hinkley proposal on the Planning Inspectorate's website.
