London’s Heathrow Airport announced a complete shutdown all day Friday due to a “significant power outage” due to a large fire nearby, causing massive disruption to one of the world’s busiest travel hubs as flights were forced to turn back midair or divert to other locations.
“Due to a fire at an electrical substation supplying the airport, Heathrow is experiencing a significant power outage,” Heathrow Airport said in a statement on X. “To maintain the safety of our passengers and colleagues, Heathrow will be closed until 23h59 on 21 March.”
“We expect significant disruption over the coming days and passengers should not travel to the airport under any circumstances until the airport reopens,” the airport said in a statement to CNN, adding that they “do not have clarity on when power may be reliable restored.”
A transformer at an electrical substation in Hayes, a London suburb located just a few miles from the airport, caught fire Thursday night, according to the London Fire Brigade. The cause is not yet known, and firefighters were still working to extinguish the blaze as of early Friday morning.
The brigade said it evacuated 150 people from the area. More than 16,000 homes lost power, according to utility supplier Scottish and Southern Electricity Networks.
Heathrow Airport appeared largely dark amid the power outage, according to videos shared on social media.
