Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, what proportion of UK electricity demand was met by a) wind and b) solar generation during periods of low wind and low sunlight in the last 12 months.

The Department does not hold this data. Half-hourly demand figures and estimated wind and solar generation for Great Britain, are published by NESO. Weather data is available from the Met Office.
