Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, how many days was more than 10 per cent of UK electricity demand imported between 1 November 2024 and 30 April 2025.

The Department does not record daily electricity demand or import data. Half-hourly figures for electricity demand and import for Great Britain’s public distribution system are available from the National Energy System Operator (NESO) data portal. Quarter-hourly figures for Northern Ireland’s electricity demand from the public distribution system are available from EirGrid.
