Madrid/Lisbon — Electricity has been restored to the majority of the Iberian Peninsula after a massive and sudden blackout plunged much of Spain and Portugal into darkness on Monday, halting transport, closing businesses, and disrupting daily life across the region.

By 4 a.m. Tuesday, Spain’s national grid operator, Red Eléctrica de España (REE), confirmed that 87.37% of the country’s electricity supply had been restored, following what authorities describe as one of the most widespread outages in recent history. Portuguese grid operator REN reported a full stabilization of its network by midnight, with all power substations operational.

Spanish Prime Minister Pedro Sánchez, in a televised address Monday night, announced that 50% of Spain’s electricity had already been restored, calling it a “challenging but coordinated national effort.” He urged patience, acknowledging that full restoration was still ongoing and that some workers would need to remain home Tuesday due to the continuing disruption.

“The challenge is to continue restoring power in the coming hours,” Sánchez said, stopping short of providing a definitive timeline for full recovery.

The Cause: Still a Mystery

The origin of the blackout remains unclear, with conflicting statements from Spanish and Portuguese leaders. Portuguese Prime Minister Luís Montenegro suggested the cause likely stemmed from Spanish territory, while Spain’s Sánchez insisted that “no theory or possibility is excluded” and that all potential causes are under investigation.

Some Portuguese officials speculated that a rare atmospheric phenomenon involving sharp temperature fluctuations may have triggered the event, though this has yet to be confirmed by scientific authorities.

The blackout struck early Monday, sending both countries into disarray. Public transportation, particularly Spain’s rail system, suffered extensive delays and cancellations, with trains in many areas still not fully operational as of Tuesday morning.

Recovery in Progress

Despite the chaos, both REE and REN expressed confidence in their systems’ resilience. Spain’s grid was reportedly “virtually” meeting demand by early Tuesday, and no additional large-scale power disruptions were reported overnight.

“The recovery is progressing rapidly thanks to our emergency protocols and cross-border coordination,” said a spokesperson from Red Eléctrica.

With electricity largely restored, attention is now turning to investigating the root cause and reinforcing both nations’ energy infrastructures to prevent a similar crisis.
