A whistleblower has claimed that power cuts in Britain are imminent if the National Energy System Operator (Neso) does not address ongoing issues. The anonymous engineer stated that staff in Neso's control room still depend on pen and paper to forecast electricity demand, using handwritten notes and historical data due to inadequate computer systems. They criticized Neso's Open Balancing Platform (OBP), which manages the electricity grid, alleging it wastes consumer funds by providing poor visibility of the network and sometimes neglecting to utilize batteries for power dispatch.
This statement follows leaked documents indicating that the network was nearly shut down on June 23 due to insufficient wind and solar energy during extreme heat. In response, energy regulator Ofgem initiated an investigation in July into the whistleblower's allegations regarding Neso's operational decision-making and record-keeping.
The engineer expressed skepticism about the investigation's outcome, suggesting it would conclude that the system was secure, but this would not reflect the reality. They stated, 'We were right on the limit... for some reason the execs came out right away and said, 'We're completely secure'.' They also mentioned reliance on interconnectors to Europe, stating that this is not a dependable solution.
The engineer warned, 'Sadly it is just a matter of time before we have a partial blackout,' criticizing senior management for prioritizing image over system integrity. Neso has denied the claims that operational concerns are routinely ignored and that power cuts are imminent. They also refuted allegations that the control room relies on paper-based forecasting and that the OBP overlooks cheaper energy sources.
Previous whistleblower reports indicated that Neso executives were endangering lives by not acknowledging the system's precarious state. Control room engineers reported routine safety breaches and warned of a potential catastrophic blackout. Energy consultant Kathryn Porter noted that the national grid is currently more fragile than at any time since its privatization in 1990, criticizing Neso's plans to operate with reduced levels of 'inertia' to save costs, which she believes increases blackout risks.
A Neso spokesperson emphasized that all allegations are taken seriously and that no conclusions from the independent review have been published yet. An Ofgem spokesperson confirmed that they are reviewing the management of the electricity system during the June heatwave and the associated whistleblower concerns, ensuring that the investigation will be thorough and transparent.
