Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, if his Department will publish nuclear infrastructure modelling for nuclear projects in the UK.

The Department conducts power market modelling using the Dynamic Dispatch Model (DDM). The DDM is a comprehensive fully integrated power market model covering the GB power market over the medium to long term. Analysis published using this model, such as Modelling 2050 – electricity system analysis - GOV.UK, has shown the importance of nuclear to obtaining low-cost low-carbon solutions to future electricity supply. The DDM has also been used to inform value-for-money assessments, such as the final investment decision on Sizewell C. Sizewell C: Value for money assessment - GOV.UK.
