On Monday 28 April, a massive power outage swept through Portugal and Spain, plunging major airports into disarray. The outage, described as a \u201crare atmospheric phenomenon\u201d by Portugal\u2019s grid operator REN, disrupted critical infrastructure, grounding flights and stranding thousands of passengers.
\nThe outage also briefly affected parts of France, similarly impacting infrastructure, including major airports, leading to widespread travel chaos.
\nAccording to aviation analytics firm Cirium, the impact on air travel was significant, with cancellations and delays rippling across the Iberian Peninsula.
\nWidespread Flight Cancellations
\nCirium reports that 96 flights departing Portuguese airports were canceled on April 28, with Lisbon\u2019s Humberto Delgado Airport hit hardest. Over the day, 29.63% of its departures were scrapped, contributing to chaotic scenes at the terminal.
\nIn Spain, 45 flights were canceled, with Barcelona-El Prat Airport seeing 2.98% of departures cut and Madrid-Barajas Airport losing 2.56%. Notably, no flights from the UK to Spain were canceled, but nine UK-to-Portugal flights were grounded, affecting connectivity.
\nThe scale of scheduled operations underscores the disruption\u2019s impact. Spain planned to manage 3,005 departures and 3,005 arrivals, with Madrid, Barcelona, and Palma serving as the busiest hubs.
\nPortugal expected 709 departures and 722 arrivals, primarily through Lisbon, Porto, and Faro. Meanwhile, the UK had 399 departures to Spain, representing over 75,000 seats, and 105 to Portugal, equating to nearly 20,000 seats.
\nThe cancellations, though a fraction of total flights, caused significant inconvenience, particularly in Lisbon.
\nAirports in Crisis
\nLisbon\u2019s airport faced the worst of the crisis. With 29.63% of departures canceled, the airport closed to arrivals for much of the day, and operations were not expected to resume until late evening.
\nPassengers reported dark terminals, no air conditioning, and limited amenities, with shops accepting only cash due to payment system failures.
\nTAP Air Portugal urged travelers to stay away, while police managed crowds at entrances. Porto and Faro airports fared better, relying on backup generators to maintain limited operations.
\nIn Spain, Madrid-Barajas operated at 80% capacity, with air traffic reduced to 20 landings per hour. Iberia canceled 23 of its 247 flights, offering passengers rescheduling options.
\nBarcelona\u2019s airport, despite 2.98% cancellations, managed minor delays for some flights, supported by contingency generators.
\nOther airports, like Seville and Valencia, faced disruptions but restored partial functionality. Airlines like easyJet and Ryanair reported issues, with easyJet offering free transfers or vouchers for affected passengers.
\nCause and Response
\nThe Portugal and Spain power outage stemmed from extreme temperature variations in Spain\u2019s interior, causing oscillations in high-voltage lines and grid synchronization failures. While early speculation suggested a cyberattack, authorities in both countries ruled this out.
\nSpain\u2019s Red El\u00e9ctrica restored over 35% of power by late April 28, with full recovery expected within 6\u201310 hours. Portugal prioritized hospitals, airports, and railways, but full grid restoration could take a week.
\nAirport operators like Aena (Spain) and ANA (Portugal) activated emergency plans, urging passengers to check flight statuses. Ground transportation disruptions, including metro evacuations in Madrid, further complicated airport access.
\nAirlines advised travelers to monitor updates and avoid unnecessary trips to affected hubs, particularly Lisbon.
\nThe power outage has exposed vulnerabilities in the region\u2019s infrastructure, but recovery is underway. Travelers should stay informed and flexible as Portugal and Spain work to restore normalcy to their airports.<\/p>\n","protected":false},"excerpt":{"rendered":"
