An independent investigation into Great Britain's National Energy System Operator (Neso) has found significant cultural, governance and control problems, although it did not uphold whistleblowers' claims of a cover-up over blackout risks.
Control room staff had alleged that senior managers played down how close the grid came to failing during the June heatwave, when frequency repeatedly fell below normal limits and help was needed from neighbouring countries. The law firm Eversheds Sutherland found no evidence of improper influence on operational decisions, but reported high stress among engineers and a sense that their concerns went unheard, according to the Guardian.
Neso's chief executive, Fintan Slye, said the company would act on the recommendations. The regulator Ofgem is running its own inquiry, due by 31 March 2027, and energy minister Michael Shanks said he expected swift action.
