Sizewell C proposals

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

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.

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.

Nuclear power from Sizewell C will deliver low-carbon electricity which doesn't depend on the weather and will work alongside renewables to reduce the UK's carbon emissions.

On 25 February the Planning Inspectorate submitted to the Secretary of State its report and recommendation on whether to grant Sizewell C a Development Consent Order (DCO). This followed a six-month examination process that ran between April-October 2021. The Secretary of State will now have until 25 May to make a decision on whether to approve the DCO application, which would provide us with consent to build Sizewell C.
