Sizewell C proposals

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.
