In the wake of a nationwide blackout, Spanish officials are urgently investigating the cause of the outage that impacted daily life across the country and neighboring Portugal.

Spain's Prime Minister and top security officials convened to explore the causes behind a widespread blackout that left millions without power. Questions linger about the potential link to the national grid's shift towards renewable energy, and authorities are conducting investigations to rule out various possibilities, including cyberattacks.

Spain’s authorities are under immense pressure following a massive power outage that plunged the Iberian Peninsula into darkness for up to 18 hours. On Wednesday morning, key figures including Prime Minister Pedro Sánchez gathered in Madrid to address the crisis that halted regular life across Spain and Portugal since Monday afternoon.

The blackout has sparked significant concern regarding the reliability of Spain's national grid, Red Eléctrica, particularly after its recent shift towards renewable energy sources. It has raised alarms about potential vulnerabilities within the grid which could have contributed to this outage.

Amid these discussions, Sánchez announced the establishment of a commission led by the Ministry for the Ecological Transition, specifically tasked with investigating the incident. Authorities are considering multiple factors behind the blackout, with Red Eléctrica clarifying that no evidence of a cyberattack has surfaced so far. However, a local judge ordered an immediate inquiry from Red Eléctrica, intelligence services, and law enforcement to determine if cyber interference played a role in the outage.

The National Cryptologic Center is currently examining cyberthreat risks related to the electrical emergency. Mr. Sánchez stated in a recent press conference that all relevant data and records are undergoing scrutiny to ensure a comprehensive understanding of the situation.

After power was restored, Spain’s Interior Ministry announced the downgrading of emergency declarations in most areas, though Madrid and Extremadura retained higher alert levels due to the ongoing complications in those regions.

The investigation continues as millions remain curious about the implications for Spain's energy future and the reliability of its power infrastructure.
