A massive and unprecedented power outage struck Spain and Portugal on Monday, disrupting daily life across both nations and leaving millions without electricity. Spanish grid operator Red Eléctrica warned that full restoration could take between six to ten hours, while Portuguese authorities confirmed the blackout was not linked to a cyberattack.
The outage crippled major infrastructure — shutting down subway systems, phone lines, ATMs, traffic lights, and even suspending play at the Madrid Open tennis tournament. Spanish Prime Minister Pedro Sánchez visited Red Eléctrica to monitor recovery efforts, while Portugal’s Cabinet convened an emergency meeting.
Officials suggest the disruption stemmed from problems in Spain’s electricity distribution network, affecting parts of France as well. Portugal’s main distributor, E-Redes, stated it was a “European electricity system issue,” leading to targeted power cuts to stabilize the network.
Electricity demand in Spain plunged dramatically around 12:15 p.m., and videos showed empty metro stations and halted trains in cities like Madrid and Barcelona. Traffic chaos ensued, prompting authorities to ask citizens to minimize road travel. Meanwhile, towns like Terrassa saw generator sales surge as residents prepared for extended outages.
Hospitals, gas stations, courts, and public transport systems across Portugal switched to backup power, while police ramped up patrols to manage rising emergency calls and direct traffic.
Although both countries have begun gradual recovery, the scale and rarity of the blackout have spotlighted vulnerabilities in Europe’s interconnected power grid.
