Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, what comparative assessment he has made of the potential merits of (a) small nuclear power plants and (b) large-scale solar farms.

As set out in the Clean Power 2030 Action Plan, a power system run on low carbon generation with renewables providing the vast majority of generation, supported by nuclear, can form the basis of a clean, affordable and secure energy system. This assessment was supported by independent advice from the National Energy System Operator (NESO), whose clean power scenarios highlighted the importance of different technologies working in combination. The Department continues to model a range of different energy mixes and scenarios to support policy decisions.

Alongside the Scottish and Welsh Governments, we have also jointly commissioned NESO to develop a Strategic Spatial Energy Plan (SSEP). The SSEP will assess infrastructure potential on a zonal basis as well as the quantities and types of energy infrastructure required to meet our future energy demand with the clean, affordable and secure supply that we need. The first SSEP will be published in 2026.
