To ask Her Majesty's Government whether nuclear plants are currently able to provide one fifth of UK electricity supplies.
2 June 2021
The total installed nuclear capacity in the UK is 8.9 GW and if all stations were fully operational they could provide more than a fifth of UK electricity supplies. However, a proportion is likely to be unavailable at any given point due to routine inspections, maintenance and technical issues.
In 2020 nuclear power stations generated around 16% of the electricity generated in the UK. This figure is provisional and final figures will be published in July in the Digest of UK Energy Statistics (DUKES: the annual energy statistics publication produced by the Department for Business, Energy and Industrial Strategy).
