Yesterday, Spain, Portugal, and parts of France plunged into darkness as a massive power outage swept across the Iberian Peninsula.
Today, the lights are back on, with Spain’s grid operator, Red Eléctrica, confirming that over 99% of mainland Spain has power again.
But what caused this unprecedented blackout, and what did it spark among panicked shoppers? Here’s the breakdown.
A Nation in the Dark
On Monday, April 28, 2025, at 12:33 p.m., Spain’s power grid suffered a catastrophic failure.
Traffic lights went out, trains stopped, ATMs froze, and telecom networks faltered, leaving millions scrambling.
Eduardo Prieto, head of operations at Red Eléctrica, called it an “exceptional and extraordinary” event.
By Tuesday morning, April 29, power was restored to nearly all affected areas, thanks to tireless efforts from grid operators and support from interconnections with France and Morocco.
What Caused the Blackout?
The jury’s still out, but early reports point to a “strong oscillation” in the European power grid. Prime Minister Pedro Sánchez revealed that 15 gigawatts of generation vanished in just five seconds—a staggering loss. Portuguese grid operator REN hinted at a “rare atmospheric phenomenon” tied to extreme temperature swings, but no hard evidence has surfaced. Sánchez hasn’t ruled out a cyberattack, though EU and Portuguese officials have downplayed that theory. Investigations are ongoing to pinpoint the exact trigger.
Panic Buying Empties Supermarkets
As the blackout gripped Spain, uncertainty fueled chaos in supermarkets, with shoppers rushing to stock up on essentials. Stores in cities like Madrid and Barcelona saw long queues and empty shelves as people grabbed water, eggs, milk, and canned goods, fearing prolonged outages. Social media users flooded platforms with complaints, venting frustration over the sudden disruption.
Many shared how they were caught amidst work, shopping, or other daily activities when the power failed, leaving them stranded or scrambling to secure supplies.
Also many stores, unable to process card payments, accepted only cash or closed entirely to prevent looting, leaving some shelves stripped bare.
Shoppers in Spain stripped shelves of essentials like water and milk as the blackout sparked panic buying.
Sánchez Speaks Out
In a televised address, Prime Minister Pedro Sánchez reassured the nation, saying, “Citizens can and should remain calm,” as power began to return Monday evening. He also highlighted the scale of the crisis, noting, “This has never happened before.” Sánchez’s government declared a state of emergency and mobilized the National Security Council to oversee recovery, with hydroelectric and combined cycle plants fired up to stabilize the grid.
What’s Next for Spain?
With power restored, the focus now shifts to prevention. The Spanish government is under pressure to uncover the root cause and strengthen the grid against future failures. For now, life is returning to normal, but the blackout and the frenzy it sparked in stores has exposed vulnerabilities in Europe’s energy infrastructure.
