The UK’s National Energy System Operator (NESO) published its summary findings of its investigation into the fire that shut down Heathrow Airport on March 20, 2025. The NESO report states that a known fault in National Grid’s electrical substation was the cause of the fire, adding that the Company was aware of the fault since 2018 but failed to fix it. According to media outlets in the UK, Heathrow airport is considering legal action against National Grid. Based on this news, ADRs of National Grid fell by more than 5% on July 2, 2025.
