Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, whether any review was undertaken of the mitigation package secured through the Sizewell C Deed of Obligation following the increase in the project’s estimated cost.

The Deed of Obligation was agreed between Suffolk Council, East Suffolk Council, and NNB Generating Company (SZC) Limited in October 2021. It sets out mitigation measures to reduce the impact of the development and operation of Sizewell C within each Councils boundary and is reflected in Requirements within the Development Consent Order. We are not aware of any review of the mitigation package in the light of increased project costs. Any application to change the Orders Requirements would need to be approved by the Secretary of State.
