Question to the Department for Energy Security & Net Zero:

To ask His Majesty's Government what plans they have to publish the independent review into allegations regarding risk of blackouts during heatwaves make by whistle-blowers from the National Energy System Operator in July.

The Government takes this matter very seriously and welcomes both the independent review into whistleblowing allegations and the separate review into grid performance during the recent period of extreme heat. Transparency will be a central principle throughout.

The Minister for Energy wrote to the Chair of NESO urging the key findings of the independent report to be published once the investigation has concluded.

Separately, NESO's post-event analysis, and Ofgem's conclusions, will be published. This will be subject to limited redactions required to protect the anonymity of individual staff members, commercially sensitive information, national security matters, or other legitimate confidentiality considerations.
