Hinkley Point C timeline

Hinkley Point C is to be the first new nuclear power station to be built in the UK for almost 20 years, set to start operation in 2025.

The main achievements regarding Government policy, market reform, investment and general developments of nuclear new build are set out below:

  • January 2009:         UK Government consultation invited nominations for sites to be assessed for their suitability for the deployment of new nuclear power stations by 2025. Ten of the 11 sites nominated were deemed potentially suitable.
  • Also 2009:                 British Energy became part of EDF Energy
  • July 2011:                 Electricity market reform white paper is issued with the intention of stabilising financial returns from low-carbon generation.
  • Nov 2012 :                 An Energy Bill is formally introduced to parliament by UK energy and climate change secretary Ed Davey. This bill is designed to encourage the development of a low-carbon energy infrastructure.
  • Dec 2012:                   National Nuclear Regulators in UK have formally approved the European Pressurised Reactor (EPR) design a PWR (pressurised water reactor) design developed by Électricité de France and Areva HP in France.
  • March 2013:               Planning permission granted for two reactors to be built at Hinkley Point C.
  • October 2013:           A Strike Price deal is made between the British government and EDF of £92.50 p/MWh agreed for Hinkley Point C for  the year 2023.
  • October 2014:           European Commissioners approve Hinkley Point Project: Brussels gives go ahead to state subsidy scheme, that offers EDF Energy a set price for 35 years.
  • Sept 2015:                  UK’s Treasury announces a £2 billion loan guarantee for Hinkley Point C.
  • Oct 2015:                    China agrees to take a one-third stake in the £18 billion project. France’s EDF share in the project will be 66.5%, and China’s CGN (China General Nuclear) will be 33.5%.
  • Sept 2016:                  The UK government decides to proceed with the first new nuclear power station for a generation. However, ministers will impose a new legal framework for future foreign investment in Britain’s critical infrastructure
  • Mar 2017:                     The UK’s Office for Nuclear Regulation (ONR) has granted its first consent for the start of construction at Hinkley Point C – concrete base only.
  • 2020:                              Reactor base for units 1 & 2 installed – the second with increased efficiency due to growth of expertise

The WNA Reactor Table has four EPRs as ‘planned’ (6680 MWe) and seven units ‘proposed’.
The PRISM and EC6 options for Sellafield are alternatives for Pu disposition.
