Five things we now know about the fire that shut Heathrow down

A recent report by the National Energy System Operator (NESO) outlines key findings about the fire that caused Heathrow Airport to shut down. The fire, caused by moisture in a supergrid transformer, led to power cuts at the airport affecting over 200,000 passengers. The report reveals that National Grid was warned about a fault seven years prior but failed to address it, leading to the catastrophic failure of the transformer. Additionally, the report highlights the lack of communication between energy suppliers and critical national infrastructure (CNI) operators, emphasizing the need for better coordination to prevent future disruptions.
