A large-scale power outage swept across Spain, Portugal and parts of southern France on Monday, crippling public transport, causing flight delays, and prompting emergency government meetings. Residents as far afield as Andorra and Belgium also reported being impacted as authorities raced to restore electricity to millions.
The outage, which struck in the early hours of 28th April, left much of the Iberian Peninsula in chaos. Spain’s Red Electrica and Portugal’s REN, the respective national grid operators, confirmed widespread disruptions and said coordinated plans for the phased restoration of power were being activated in collaboration with European energy authorities. Although France experienced only a brief outage, areas bordering Spain were temporarily affected, while Belgium also reported isolated incidents.
In Madrid, parts of the underground metro system were evacuated, traffic jams clogged the city centre, and police were deployed to direct vehicles through streets where traffic lights had failed. Office workers flooded onto the pavements amid evacuations of high-rise buildings, including one that houses the British Embassy. Local reports detailed dozens of people trapped inside stalled metro cars and elevators as the city struggled to respond.
Portugal faced similar chaos, with traffic lights failing nationwide and metro services grinding to a halt in Lisbon and Porto. Lisbon’s airport operated on backup generators as national airline TAP reported disruptions. Meanwhile, Spain’s airport authority AENA announced delays across its 46 managed airports, deepening travel frustrations for thousands of passengers.
While power was swiftly restored in France, grid operator RTE has launched an investigation into the cause of the outage. REN in Portugal said the reasons behind the failure are still under assessment but assured that energy supply restoration efforts remain ongoing, coordinated closely with civil protection authorities.
