A massive and sudden power outage brought large swathes of Spain and Portugal to a halt on Monday, paralyzing infrastructure, grounding flights, halting metros, and sparking panic buying across major cities. The outage began around 10:33 GMT, with power still not fully restored by the afternoon.
The scale and impact of the outage—described as one of the most significant in Europe in recent decades—prompted emergency cabinet meetings in both countries. Governments are investigating the source of the disruption, which has yet to be conclusively identified.
Widespread Disruption and Confusion
Public transport systems were among the hardest hit. In Madrid, metro lines were shut down and partially evacuated, while Lisbon’s subway system also ground to a halt, leaving passengers stranded underground. Trains stopped running in major cities across both countries.
Airports including Lisbon and various hubs managed by Spain’s AENA reported delays as they switched to backup generators. At Madrid’s Atocha railway station, stranded travelers voiced frustration.
“I just don’t know who to turn to. My daughter in Barcelona is giving birth. We’re going to miss the connection to get there,” said Angeles Alvarez, one of many impacted commuters.
Traffic lights failed, causing gridlock in city centers and prompting police and volunteers in reflective vests to manually direct traffic. Madrid’s mayor, Jose Luis Martinez-Almeida, urged residents to stay put and avoid unnecessary travel to clear roads for emergency services.
Hospitals and Businesses Affected
In Spain’s Madrid and Cataluña regions, hospitals suspended all non-urgent operations, relying on emergency generators to treat critical patients. Across both countries, businesses like Lidl and IKEA temporarily shut their doors.
Electronic banking held up for the most part, but some ATMs went offline, and data centers, including those in Barcelona, experienced complete shutdowns.
“Everything has gone off. All the alarms popped up… now we’re just waiting to find out what happened,” said Jose Maria Espejo, an engineer in a Barcelona data center.
Panic Buying and Water Supply Fears
The outage also sparked a wave of panic buying. Supermarket shelves in Madrid emptied quickly, and long queues formed at gas stations and supply stores, with people stocking up on generators, gaslights, and batteries.

In Portugal, water utility EPAL warned of potential disruptions in water supply, adding to the growing anxiety.
Partial Restoration and International Response
Some power began to return by the afternoon in regions like the Basque Country and Barcelona, but the timeline for full restoration remained unclear. French grid operator RTE stepped in to supplement electricity to northern Spain, underlining the seriousness of the crisis.
While widespread power failures are rare in Europe, there have been notable precedents:
- In 2003, a hydroelectric issue between Italy and Switzerland triggered a 12-hour blackout.
- In 2006, an overloaded German network caused outages across Western and Southern Europe.
According to Ember, an energy think tank, 43% of Spain’s electricity comes from renewables (wind and solar), 20% from nuclear, and 23% from fossil fuels—suggesting a failure in grid coordination or transmission, rather than energy supply.
Next Steps and Government Reassurances
Spanish Prime Minister Pedro Sanchez addressed the nation, calling for calm:
“We do not yet have conclusive information on the reasons for this cut… There are no problems of insecurity.”
He confirmed that Spain’s National Security Council would reconvene Monday evening to assess the situation.
Meanwhile, Portugal’s main utility company EDP said there was no estimated time for full restoration, cautioning that it could take several hours more to normalize the grid.
