Massive Blackout Brings Spain and Portugal to a Standstill

Barcelona, Spain — A massive, unexpected blackout swept across Spain and Portugal on Monday, paralyzing major cities, stranding thousands of commuters, and leaving millions without power, internet, or access to cash machines.

The outage, which began just after noon, triggered chaos across the Iberian Peninsula. Offices and public services shut down, trains halted mid-journey, and even emergency services had to scramble as backup generators kicked in.

“This is unprecedented,” said Spanish Prime Minister Pedro Sánchez during a national address. “We have never had a complete collapse of the system.”

According to Sánchez, Spain’s power grid lost 15 gigawatts — around 60% of national demand — in just five seconds. Eduardo Prieto, head of operations for Spain’s electricity distributor Red Eléctrica, described the event as “exceptional and extraordinary.”

By late Monday night, about half of the electricity supply had been restored. Sánchez promised that full power would return across Spain’s 48 million residents by the end of Tuesday.

Authorities are still investigating the cause, though officials in both Spain and Portugal have ruled out a cyberattack. Teresa Ribera, a European Commission vice president, called it “one of the most serious episodes recorded in Europe in recent times.”

The blackout hit hard in Madrid, Lisbon, Barcelona, and other major cities. Offices closed, traffic lights went dark, and massive traffic jams formed. In Barcelona, civilians were seen directing traffic themselves to keep roads moving.

Public transportation ground to a halt. Over 35,000 passengers had to be evacuated from more than 100 stalled trains across Spain. As of late Monday, 11 trains still had passengers awaiting evacuation.

At Madrid’s main bus stops, desperate travelers tried to hitch rides to the airport, holding up handmade signs asking for help.
“I’ve been here for almost three hours. My family just arrived, and I can’t even contact them,” said Jessica Fernández, one of many stranded commuters.

Subways in both Spain and Portugal also shut down, forcing thousands to walk or search for scarce taxis and buses.

Hospitals quickly switched to backup generators. Gas stations stopped operating, and mobile networks largely collapsed, making it almost impossible to make calls or use data.

The Spanish army was mobilized to distribute generators and essential supplies to the hardest-hit regions after an emergency National Security Council meeting.

Portugal’s government, meanwhile, held an emergency cabinet meeting. Prime Minister Luís Montenegro confirmed that the problem appeared to have originated outside Portugal, and that Lisbon was working closely with Spain to restore power.

To help speed recovery, Spain started importing electricity from Morocco and France and boosted production from hydroelectric and thermal power plants.

Spanish airports switched to backup systems. Flight delays were reported, but most operations continued. In Lisbon, however, terminals closed temporarily, leaving tourists waiting outside without information.

Spain’s Parliament shut down for the day. Matches at the Madrid Open tennis tournament were suspended. Meanwhile, courts, public offices, and ATM networks across both countries ground to a halt.

In cities like Barcelona, many residents poured into parks, beaches, and restaurant terraces to wait it out, with some trying to find a silver lining.
“We are lucky. Some people are stuck underground in the metro. At least we’re talking more to each other,” said Monste Cortés, who spent the afternoon chatting with neighbors.

As evening fell and hours without communication dragged on, anxiety spread.
“I can’t even call my boss because nothing works,” said Helen Osorio, a shop clerk in Barcelona.

In Terrassa, an industrial town near Barcelona, shops selling battery generators quickly sold out as residents rushed to find ways to stay connected.

Police in Portugal reported an uptick in emergency calls, especially from people trapped in elevators and subway cars.

Despite the disruptions, there were no reports of serious injuries. Both governments assured citizens that restoring power and stabilizing the grid remained their top priority.

At a glance:

• Blackout affected over 60 million people across Spain and Portugal.
• 15 gigawatts of power lost in seconds.
• No evidence of cyberattack so far.
• Power restoration expected by Tuesday evening.
