National Grid boss claims London Heathrow Airport had ‘enough power’ despite shutdown.
Heathrow Airport defended its decision to shut down operations at Europe’s busiest airport on Friday as the blame game intensified over an 18-hour closure that cost airlines tens of millions of pounds and stranded thousands of passengers.
As questions mounted over how such a critical part of Britain’s infrastructure could fail and whether all Heathrow’s four terminals needed to shut, both National Grid and Heathrow agreed that the failure of the transformer was an unprecedented event.
But the airport was forced to defend its closure after the boss of National Grid told the Financial Times that the electricity transmission network remained capable of providing power to the airport throughout the crisis.
Heathrow said the fire at a nearby substation late on Thursday interrupted its operations, forcing it to shut while it reconfigured systems and switched to power from an alternative substation.
“Hundreds of critical systems across the airport were required to be safely powered down and then safely and systematically rebooted,” a Heathrow spokesperson said.
John Pettigrew from National Grid said there were two other substations “always available for the distribution network companies and Heathrow to take power”. “Each substation individually can provide enough power to Heathrow.”
