National Energy System Operator probe finds governance issues

An independent investigation by law firm Eversheds Sutherland into the National Energy System Operator (Neso) has found no evidence that staff engaged in a cover-up regarding blackout risks during summer heatwaves. The probe was launched following whistleblower allegations that control room staff were encouraged to alter or suppress records to avoid public scrutiny or reputational damage during a period of extreme heat between June 22 and 26.

While the specific allegations of record tampering were not substantiated, the report highlighted significant cultural and governance issues within the organization. Investigators noted a “culture of perceived non-response,” where employees felt their concerns regarding the stability of the energy grid were sidelined to keep the government and regulators “happy.”

The report identified high levels of stress within the national control centre, driven by increasing network demands and the challenges of the UK’s transition to net zero. Witnesses claimed that a desire to maintain positive relationships with external stakeholders led to staff concerns being “largely unheard,” creating an environment where employees felt there was little point in raising operational issues.
