A massive blackout plunged Spain and Portugal into darkness on Monday, April 28, 2025, after an unprecedented and unexplained disappearance of 15 gigawatts of electricity from Spain’s power grid. The incident, described by Spanish Prime Minister Pedro Sánchez as “something that has never happened before,” left millions without power and triggered urgent investigations.
Speaking at a late-night press conference, PM Sánchez conveyed the gravity of the situation, emphasizing that experts are working tirelessly to determine the cause of the power loss. “No hypothesis has been rejected, and every possible cause is being investigated,” he said, underscoring the complexity and rarity of the event.
The blackout affected vast areas across the Iberian Peninsula, disrupting homes, businesses, and critical infrastructure. Authorities in both Spain and Portugal mobilized emergency services to manage the fallout and restore electricity as quickly as possible.
Energy officials are collaborating with European grid operators to analyze the incident, given the interconnected nature of the continent’s power systems. The sudden loss of such a large amount of power raises concerns about grid stability and the potential risks to energy security in the region.
As investigations continue, the Spanish government has assured citizens that restoring power and preventing future occurrences are top priorities.
