Nuclear Power: Energy Supply

Asked by Dame Chi OnwurahLabourDepartment for Energy Security and Net ZeroTabled Answered 22 January 2025UIN 23757

The question

To ask the Secretary of State for Energy Security and Net Zero, what his Department's target is for nuclear capacity in gigawatts by (a) 2030, (b) 2040 and (c) 2050.

Answered by Michael Shanks

Nuclear power currently provides ca. 15% of the UK’s electricity (6GW). As the current fleet retires, the Clean Power Action Plan anticipates a drop in capacity to 3-4GW in 2030.

We see nuclear as an important part of the mix going forward and are pushing ahead with building new nuclear. We have committed to getting Hinkley Point C over the line and will take final decisions on Sizewell C and the Great British Nuclear-led Small Modular Reactor programme at the Spending Review.
