Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, whether unanticipated cost increases for Sizewell C will fall on consumers under the proposed Regulated Asset Base financing model.

The National Audit Office assessed that models such as RAB could have resulted in better value for money to consumers if they had been applied to Hinkley Point C.

Our plans for implementing the RAB model for nuclear include multiple safeguards to protect consumers’ interests. These include robust due diligence according to HM Treasury Green Book guidance prior to any final investment decisions and implementing an incentives regime for projects to manage cost and schedule.
