The question

To ask the Secretary of State for Energy Security and Net Zero, what assessment his Department has made of the potential impact of EDF increasing its equity stake in Sizewell C to on the adequacy of the project's (a) commercial financing model and (b) risk allocation among public and private stakeholders.

Answered by Michael Shanks

EDF has announced it will in principle invest into Sizewell C such that its stake in the project would be 12.5% following a final investment decision (FID).

Details of the commercial structure of Sizewell C are commercially sensitive as we conclude the capital raise process – further details will be published at the point of FID.

Sizewell C is expected to support around 10,000 jobs at peak construction and thousands more in the wider supply chain, as well as creating 1,500 apprenticeships. Sizewell C has 3500 UK suppliers and plans to award 70% of construction value to UK businesses.

This Government is committed to attracting the investment required to deliver future nuclear projects. The UK has long established relationships with international partners considering civil nuclear deployment.
