PARLIAMENTARY WRITTEN QUESTION
(29 May 2026)

To ask the Secretary of State for Energy Security and Net Zero, what assessment his Department has made of the extent to which priority system-level datasets supporting the operation of a renewables-led electricity system are (a) clearly defined and (b) published openly as standard.

Asked by:
Claire Young (Liberal Democrat)

The electricity system in Great Britain is operated by the National Energy System Operator (NESO), which uses a wide range of datasets to support system operation and publishes a substantial amount of this data through its public data portal. Where data is not made public this will be for reasons such as commercial sensitivity or system security.
