Heathrow Airport Power Outage: Firefighters Fight Massive Blaze at Electrical Substation
A tumultuous night in London as a significant fire at an electrical substation disrupts power to Heathrow Airport and thousands of homes.
In the early hours of March 21, 2025, the London Fire Brigade confirmed that firefighters were deployed to combat a fierce blaze at an electrical substation in Hayes, just two miles from Heathrow Airport. The incident has already affected power to Gatwick and led to widespread outages across the region.
By 4 a.m., a significant portion of the transformer was still ablaze, with fire crews warning that the situation was evolving and disruptions were likely to escalate. "This will be a prolonged incident, with crews remaining on the scene throughout the night," stated Pat Goulbourne, assistant commissioner of the London Fire Brigade.
Authorities have set up a cordon 650-feet around the substation and evacuated approximately 150 people as safety measures are enforced. Thick smoke was visible from the site, and the cause of the blaze remains undetermined as firefighters continue their efforts into the morning hours.
Residents are advised to stay clear of the area while the situation develops further.
