Name of the Project
Hinkley Point C nuclear power plant (NPP) project.

On a site to the west of the existing Hinkley Point A and B power stations in West Somerset, in the UK. 

Project Owner/s
Nuclear New Build, a subsidiary created by EDF Energy.

Project Description
The project will involve the construction, operation and maintenance of a new nuclear power station, known as Hinkley Point C.

The development will include:
• two UK European pressurised reactors with a combined output of 3 200 MW, associated buildings and a plant;
• staff facilities, offices, workshops and storage buildings;
• cooling water tunnels and associated infrastructure, including a fish recovery and return system;
• fuel and management facilities, including for spent fuel and intermediate waste;
• a sea wall, incorporating a public footpath;
• a national-grid 400 kV substation and overhead power lines on site;
• a public information centre;
• a temporary jetty;
• an emergency access road;
• access and parking facilities for workers, visitors and deliveries; and
• a temporary accommodation campus, including 510 bed spaces.

The new power plant will be capable of generating up to 3 260 MW.

The power station is expected to operate for about 60 years.

Potential Job Creation
Construction and operation of Hinkley Point C will create about 25 000 employment opportunities and up to 1 000 apprenticeships. An estimated 64% of the project’s construction value is predicted to go to UK companies.

Capital Expenditure
Delays arising from the Covid-19 pandemic will increase the cost of the project to £23-billion.

Planned Start/End Date
The start of electricity generation from Unit 1 is expected in June 2026, compared with the end of 2025 as initially announced in 2016.

Latest Developments
The first of eight 520 t steam generators has been delivered to the construction site.

The 25-m-long steam generators will take heat from the nuclear reactors to create steam to power the world’s largest turbines. The generator has arrived in time for the fit-out of the new power station, which will result in the first nuclear reactor installed later this year.

Four generators will be placed in each reactor building, operating at an average temperature of 295 °C for at least 60 years.

Key Contracts, Suppliers and Consultants
