State-run NESO Falters, Prompting Ofgem Probe and Warning for New Grid Plan

The National Energy System Operator (NESO), formed from the private National Grid and transferred to state control on 1 October 2024, is struggling to manage Britain’s electricity network. Within two years it has been unable to produce reliable supply-demand forecasts, missed required risk-and-planning reports, and its annual frequency risk control report has been suspended. During the June heatwave the grid approached a critical point, prompting Shadow Energy Secretary Claire Coutinho to reveal multiple whistleblower allegations: a breach of grid-security standards on 23 June, interference by the corporate-affairs team in operational choices, and the absence of an audit trail for live decision documents.

Ofgem launched a formal investigation two days after the parliamentary statement, and a confidential one outlet's report confirmed NESO is “flying blind,” raising the risk of blackouts and higher bills. Chief executive Fintan Slye was forced to withdraw from updates on the probe after public outcry, while NESO allocated £75,000 plus VAT to locate the staff who leaked the information rather than addressing the near-miss. The failures raise doubts about the viability of Burnham’s upcoming state-owned energy grid initiative.
