Heathrow airport faced delays in resuming operations after a substation fire hit its power supply. The incident occurred at the airport’s energy management centre, which supplies electricity to its terminals and facilities. The exact cause of the fire is still under investigation, but it has been confirmed that a transformer was damaged in the blaze. As a result, airport authorities had to rely on backup generators to maintain essential services. A full restoration of power is expected once the substation is repaired and upgraded with new equipment. Authorities are urging passengers to check for updates before traveling to Heathrow.
