Tom Watters, director of Sanguine Impact Investments, told MailOnline the crucial substation powering Heathrow contains 'very old' equipment and blamed a 'lack of investment'.
An expert claims an old transformer failure caused a Heathrow substation fire, stranding hundreds of thousands. The fire involved 25,000 litres of cooling oil. A 2022 report flagged issues with the Heathrow area's electricity supply, noting the substation was running over capacity. Flights are resuming with priority for stranded passengers.
