An anonymous whistleblower says power cuts could be “a matter of time” unless senior leaders at the National Energy System Operator (Neso) address operational problems. The claims focus on how forecasting and planning are carried out in Neso’s control room.

The whistleblower alleges that staff still rely on pen and paper to forecast electricity demand. The report presents this as evidence of weaknesses in processes that underpin day-to-day electricity balancing and system reliability.

The outlet does not provide additional verification or technical detail, and it is not clear from the available coverage how widespread the practice is or what specific governance or safety checks are in place. The allegation is therefore presented as a warning from an internal source rather than a confirmed finding of system failure or imminent outages.
