A massive power outage swept across the Iberian Peninsula this afternoon, plunging vast swathes of Spain and Portugal into darkness and triggering significant disruptions to critical infrastructure and essential services. The blackout, which commenced at approximately 12:00 PM GMT, has impacted major urban centers and transportation networks, leaving authorities scrambling to restore power and ascertain the underlying cause.
Reports indicate that the electricity failure has cast a shadow over key metropolitan areas including Madrid, Lisbon, Seville, Barcelona, and Valencia. The Adolfo Suárez Madrid-Barajas Airport, a major European transit hub, suffered a complete loss of power, leading to flight delays and a cascade of operational challenges for airlines and passengers. Within Madrid itself, the crucial metro and commuter rail systems ground to a halt, stranding commuters and exacerbating traffic congestion as traffic lights went dark across the city.
The impact has been equally severe in Portugal, with reports of a nationwide blackout. Lisbon Airport is also grappling with operational disruptions, mirroring the situation in the Spanish capital. Compounding the crisis, telecommunications networks have been significantly affected, leaving numerous residents across both nations without mobile phone or internet connectivity.
While the precise cause of this extensive power failure remains under intense scrutiny, early indications point towards a significant malfunction within the broader European electric grid. Unconfirmed reports suggest that a fire affecting a high-voltage transmission line connecting southern France and Spain may have played a critical role, potentially interrupting the flow of electricity exports from France to the Iberian Peninsula.
Red Eléctrica, the Spanish national grid operator, and its Portuguese counterpart, E-REDES, are working diligently to restore power supply and are actively engaged in investigating the root cause of the unprecedented outage. Sources familiar with the ongoing assessment have confirmed that the possibility of a cyberattack has not been dismissed, and cybersecurity agencies are reportedly involved in the investigative efforts.
The blackout's ramifications are being felt across a wide range of public services and scheduled events. In Madrid, sections of the underground metro system have been evacuated as a precautionary measure, and the absence of functioning traffic lights is causing widespread traffic snarls. Hospitals throughout Spain and Portugal have reported power interruptions, with healthcare facilities relying on backup generators to maintain essential patient care.
Adding to the disruption, the prestigious Mutua Madrid Open tennis tournament has been temporarily suspended due to the power outage. The blackout has impacted scheduled matches and broadcasting capabilities, leaving players and spectators in limbo.
Earlier today, large parts of Spain and Portugal were hit by major power cuts that brought certain aspects of life to a standstill. From traffic lights not working to tennis tournaments having to be suspended, the severe outage has brought significant disruption to the Iberian Peninsula. Airports serving Portugal and Spain, which rely heavily on electricity for daily operations, are facing disruptions as they come to terms with the impacts of the power outage.
Bloomberg's Javier Blas reported on X that "a loss of >10 GW of demand, from ~26GW to ~12GW in a few seconds," occurred as a result of the outage. The BBC confirmed that Red Eléctrica has acknowledged power outages across Spain. Efforts are underway to restore power, with aviation among the sectors affected by the blackouts. Aena, which manages the largest airports and heliports in Spain, stated via social media that some airports were without power.
As the situation developed, contingency generators were activated at various airports to maintain essential operations. However, reports indicate that while some airports regained power, gate screens remained dark. A passenger reported that their Madrid Metro train to the airport terminated early, requiring them to haul luggage up stairs and get taxis.
As of Monday afternoon, data from FlightAware suggested that while flights to and from Spanish and Portuguese airports were being delayed, few cancellations were reported. In Madrid, 50 departures and 30 arrivals were delayed, with just one cancellation each way. The data showed that on April 28th, 2025, there were 709 departing flights scheduled in Portugal and 3,005 in Spain.
By mid-afternoon, several hours after the blackouts were initially reported, Spain and Portugal's major airports had begun drawing up contingency plans to manage traffic amid the lack of power. Portugal's Lisbon Airport initially implemented a "zero rate" for arriving flights, before allowing planes to land at a reduced rate. Madrid Barajas Airport reduced inbound traffic to just 20 arrivals an hour, a third of the usual rate.
In the midst of this chaos, the Spanish and Portuguese governments convened emergency cabinet meetings to address the crisis. Spanish Prime Minister Pedro Sánchez visited the control center of Red Eléctrica to assess the situation firsthand. The Spanish Interior Ministry has called on the public to remain calm as recovery operations continue across the region.
As authorities work tirelessly to restore power and unravel the mystery behind this widespread disruption, the immediate focus remains on ensuring public safety and minimizing further impact on essential services. The coming hours are expected to be critical in understanding the full extent of the damage and the timeline for a return to normalcy across the Iberian Peninsula.
