On April 28, 2025, a massive power outage plunged Spain, Portugal, and parts of France into chaos, disrupting transportation, hospitals, and telecommunications. Authorities are scrambling to determine whether a cyberattack or a failure in the European electric grid caused this unprecedented blackout.
What Happened?
Millions of residents across Spain, Portugal, and parts of France, along with reported outages in the Netherlands, Belgium, and Andorra, were left without electricity on Monday, April 28, 2025. The outage, which began around late morning local time, caused widespread disruption, shutting off traffic lights, halting trains, and closing major airports like Madrid’s Barajas International and Lisbon’s Humberto Delgado. Metro systems in Madrid and Lisbon were evacuated, with passengers stranded in darkened tunnels, and hospitals, including Madrid’s La Paz, relied on backup generators to maintain operations Euronews.
Spain’s national grid operator, Red Eléctrica, reported a dramatic drop in electricity demand from 26,695 MW to 15,970 MW in seconds, describing the event as “exceptional and totally extraordinary.” By Monday afternoon, power was gradually restored in parts of northern and southern Spain, but full recovery could take 6-10 hours, with Portugal’s grid operator, REN, warning that normalization might take up to a week BBC News.
Possible Causes: Cyberattack or Grid Failure?
The cause of the outage remains unclear, with multiple theories under investigation. Spain’s National Institute of Cybersecurity (Incibe) and the National Cryptologic Center are probing the possibility of a cyberattack, given Spain’s high-profile stance on international issues like Ukraine and Gaza, which have made it a target for cyberattacks in the past POLITICO. However, European Commission Vice-President Teresa Ribera and European Council President Antonio Costa have stated there is no evidence of sabotage or a cyberattack at this stage.
Portugal’s grid operator, REN, attributed the outage to a “rare atmospheric phenomenon” involving “extreme temperature variations” in Spain, causing “anomalous oscillations” in high-voltage lines. These oscillations led to synchronization failures across the interconnected European grid, according to REN LBC News. Additionally, a fire on Alaric Mountain in southwestern France, which damaged a high-voltage power line, was cited as a possible contributing factor Anadolu Agency.
Impact on Daily Life
The blackout caused chaos across the Iberian Peninsula. Traffic lights failed, leading to gridlock in cities like Madrid, Barcelona, and Lisbon. Airports reported flight delays, and train services, including Spain’s Renfe and Valencia’s metro, were suspended. Internet connectivity dropped significantly, with Cloudflare reporting a 30% reduction in Portugal and 37% in Spain Bloomberg. Businesses, including oil refineries, shut down, and electronic payment systems froze, leaving many unable to purchase food or transportation without cash.
Social media posts highlighted the severity of the situation. One user in Spain noted, “No payments possible without cash, very limited internet, and no clue whether it’ll be resolved,” underscoring the fragility of digital infrastructure X Post.
Spain’s Response and European Coordination
The Spanish government convened an emergency session at Moncloa, with Prime Minister Pedro Sánchez visiting Red Eléctrica’s control center to oversee the response. Madrid’s mayor urged residents to minimize movement, and the National Security Council was activated to analyze the situation. The European Commission is coordinating with Spain, Portugal, and the European Network of Transmission System Operators for Electricity (ENTSO-E) to investigate the cause and ensure a swift recovery The Guardian.
