Thousands of homes have been left without power and more than 100 people were evacuated.
A fire at an electrical substation caused a power outage, leading to the cancellation of over 1,300 flights and the closure of Heathrow Airport. Limited flights resumed in the evening after the fire was deemed "non-suspicious." Heathrow's chief executive apologized for the disruption and defended the airport's response. The National Grid reconfigured the network to restore power, and airlines are working to assist affected passengers. Eurostar is adding trains to accommodate travelers.
