London’s Heathrow Airport has been forced to shut down after a massive fire broke out at a nearby electrical substation, causing a significant power outage. The blaze, which involved a transformer at the North Hyde Electricity Substation in Hayes, west London, required the response of 70 firefighters and 10 fire engines. The incident has left thousands of homes without power and prompted the evacuation of around 150 people from nearby properties.
Assistant Commissioner Pat Goulbourne of the London Fire Brigade described the situation as a “highly visible and significant incident,” with firefighters working in challenging conditions to bring the fire under control. A 200-meter cordon has been established, and residents have been advised to keep windows and doors closed due to heavy smoke.
Heathrow Airport announced the closure until at least 23:59 on March 21, 2025, warning of “significant disruption” over the coming days. Passengers have been urged not to travel to the airport, with major carriers like British Airways, Virgin Atlantic, and Delta Air Lines affected. The airport stated, “We do not have clarity on when power may be reliably restored,” and emphasized that the closure was necessary to ensure the safety of passengers and staff.
The power outage comes at a critical time for Heathrow, which recently received government backing for the construction of a third runway. Treasury chief Rachel Reeves announced the decision last month, highlighting the project’s potential to boost the UK’s economy by attracting investment, increasing exports, and enhancing global connectivity. However, the plan has faced opposition from environmental groups and some Labour Party members, including London Mayor Sadiq Khan.
As firefighters continue to tackle the blaze, the incident underscores the vulnerability of critical infrastructure and the far-reaching impact of such disruptions. Passengers are advised to monitor updates from Heathrow and their airlines for further information.
