Electricite de France (EDF) through EDF Energy (formerly British Energy Group PLC); and China General Nuclear Power Corporation (CGN) are planning to undertake the Sizewell C Nuclear Power Station project in Suffolk, the UK.

The project involves the construction of a 3,200MW nuclear reactor power station. The project will be developed in two units of 1,600MW each. EDF is planning to use Areva's EPR (European Pressurized Reactor) reactors.

The project includes the construction of water treatment systems, powerhouses, and substations, the installation of a pressure vessel, safety equipment, steam generators, moisture separator re-heaters and switch yards.

RPS has been appointed as the consultant. The scope of the contract covers sustainability advice and completing the Health Impact Assessment (HIA). Spring Agency has been appointed to support public consultation process.

In March 2010, RMJM Architects (formerly YRM) was awarded a contract by EDF to act as an overall architect. The initial contract is to prepare the master plan and to provide the architectural vision for the nuclear power plant and its associated buildings, together with the landscape design. RMJM will act as lead architect for the pre-application consultation process and for the planning application to the Infrastructure Planning Commission (IPC).

In April 2010, AMEC Foster Wheeler was awarded PMC contract and the contract will be active for a span of 11 years, with an option to extend further by four years. Under the contract, AMEC will work with EDF in the key areas of project management, engineering and construction management.

In October 2011, the project secured the planning consent for development and in early 2012 regulators granted interim approval to the type of reactor planned for the nuclear power station.

In September 2012, Grimshaw Architects and Canaway Fleming were appointed to provide design services.

On February 6, 2013, the first stage of the consultation process was completed.

On October 21, 2015, EDF Energy and China General Nuclear Power Corporation (CGN) signed a Strategic Investment Agreement for the building and operation of Hinkley Point C project, the agreement covers wider UK partnership to develop new nuclear power stations at Sizewell C and Bradwell.

Under the agreement EDF Energy will take an 80% share in Sizewell C, with CGN taking a 20% stake; subject to receiving all the appropriate consents and permissions, including planning consent and a Final Investment Decision.

In November 2016, the second stage of consultation commenced and completed on February 3, 2017.

Sizewell C Economic Assessment activities are underway and assessment will be completed in the fourth quarter of 2017. The final stage of consultation is yet to take place and no timetable has yet revealed.


The project involves the construction of a 3,200MW nuclear reactor power station at Sizewell, a small fishing village in the county of Suffolk, the UK.
