An investigation found no evidence that Britain's grid operator concealed blackout risks during summer heat.

An independent investigation has cleared staff at Britain's electricity grid operator of allegations that they covered up blackout risks. The National Energy System Operator (Neso) was being investigated over claims raised by whistleblowers, including that control room staff were encouraged to conceal or alter records during a period of extreme heat between 22 and 26 June to avoid public scrutiny or reputational damage.

Law firm Eversheds Sutherland, which conducted the investigation, found no evidence to support the allegations. The report stated: 'No witness reported receiving an instruction to delete, alter or suppress records, nor did we locate any written evidence of inappropriate version changes being made.' All witnesses also denied that corporate affairs interfered in operational decisions within the control room.

Eversheds interviewed 36 witnesses across multiple levels of seniority within Neso. While clearing the organisation of wrongdoing, the investigation identified cultural, governance and control issues requiring attention. The law firm noted there were 'high levels of stress and concern' within the electricity national control centre over increasing network demands and challenges posed by the transition to net zero.
