Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, what estimate the Government has made of the cost of nuclear energy relative to renewable sources of power.

The latest published cost and technical assumptions for power technologies, including renewables and nuclear, can be found in the published Generation Costs series. [1]

Renewables and nuclear play different roles in a decarbonising system and full power sector modelling evaluates costs at the system level. For example, analysis of many power sector scenarios [2] indicates that a cost-effective system requires a mix of technologies.
