Question to the Department for Energy Security & Net Zero:

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.

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.
