11:36 AM EDT, 03/21/2025 (MT Newswires) -- National Grid ( NGG ) shares were down 1.7% in recent Friday trading after a fire at the North Hyde substation in West London damaged equipment, resulting in the loss of power supply in the area, including at Heathrow Airport.

Despite having several power sources, the airport experienced disruption due to fire damage to a particularly important component, the BBC reported Friday, citing a National Grid ( NGG ) source.

National Grid ( NGG ) said in a post on X that a network was reconfigured to restore power to all affected customers, including "parts of Heathrow airport that are connected to North Hyde."

"This is an interim solution while we carry out further work at North Hyde to return the substation and our network to normal operation," the company said.
