The power station at a glance

Our proposals for Sizewell C will see the creation of a 3.2-gigawatt power station to provide low-carbon electricity which doesn’t rely on the weather.

Once built, Sizewell C will generate low-carbon electricity for at least 60 years and will employ 900 people, in addition to the thousands of jobs needed for maintenance outages.

Sizewell C will be built next to Sizewell B which began operating in 1995 and has so far avoided more than 76 million tonnes of carbon emissions.

The EPR reactor design has been approved by the UK’s nuclear regulator, the Office for Nuclear Regulation (ONR). This means it satisfies Britain’s high and robust standards for nuclear safety.

In July 2022, the Government approved the proposals for Sizewell C and granted the project a Development Consent Order (DCO). Read more about the decision here.

Our commitments to Britain

Our commitments to Britain highlight what the construction of Sizewell C in Suffolk will deliver for the country.

Support for the project

Support for nuclear is growing and independent polling shows our project is backed by almost two-thirds of people in East Suffolk.

Sizewell C Energy Hub

We plan to do more than produce electricity for millions of homes. By helping to kickstart other low-carbon technologies like hydrogen production and direct air capture, Sizewell C can deliver even more value to our energy system.

Supply chain

What's it like supplying a nuclear project like Sizewell C? How many companies across the country will benefit? Answers to these questions and more can be found on our supply chain page.

Jobs and skills

Sizewell C will support as many as 70,000 jobs across the UK. We will create 1,500 apprenticeships and deliver thousands of employment and training opportunities to East Suffolk.
