Introduction: A Historic Blackout Sparks Investigation
On April 28, 2025, a massive power outage swept across Spain and Portugal, plunging the Iberian Peninsula into chaos for nearly 18 hours. The unprecedented blackout disrupted transport, telecommunications, and critical services, affecting millions. Reuters Four days later, the two nations established a joint committee to uncover the cause and prevent future incidents. This article explores the outage, the committee’s mission, and the ongoing debate over its origins.
The Blackout: Unprecedented Chaos
The outage, which began at 12:33 CEST, caused a sudden loss of 15 gigawatts—equivalent to 60% of Spain’s electricity demand—within five seconds, an event Spanish Prime Minister Pedro Sánchez called “unprecedented.” CNN Traffic lights failed, trains and metros halted, and airports faced disruptions, with 20% of flights canceled. Politico Hospitals relied on generators, and businesses closed, with some, like ice cream shops in Madrid, reporting significant losses. Euronews By early Tuesday, April 29, Red Eléctrica restored 99% of Spain’s power, and Portugal’s REN reported full recovery.

On May 2, Spain’s Minister of Ecological Transition, Sara Aagesen, and Portugal’s Maria da Graca Carvalho announced a joint committee to investigate the outage’s cause and ensure it doesn’t recur. “We will collaborate to identify the causes and implement necessary measures,” Aagesen said. The committee will coordinate with European authorities, including the EU’s Agency for the Cooperation of Energy Regulators, which Portugal requested to conduct an independent audit. BBC Carvalho emphasized the complexity, noting, “This is something very complex and will take time. We need a lot of data.”

Possible Causes: From Grid Failure to Cyberattack Theories
Red Eléctrica identified two grid events, 1.5 seconds apart, in southwest Spain, possibly linked to solar power production, as a potential trigger. Eduardo Prieto, REE’s operations head, noted a “strong oscillation” caused the grid to disconnect from Europe’s system, leading to a collapse. The Guardian While a cyberattack was initially considered, REE and Portugal’s government ruled it out, citing no evidence of system intrusion. The Independent Spain’s High Court, however, continues to probe cyberterrorism as a possibility. Wikipedia A debunked theory attributed the outage to a “rare atmospheric phenomenon,” which Portugal’s REN clarified was falsely attributed to them.

The outage exposed vulnerabilities in the Iberian Peninsula’s integrated energy grid, often described as an “energy island” due to limited interconnections with France. Politico Some analysts question whether Spain’s reliance on renewables (43% from wind and solar) contributed to grid instability, though Sánchez and REE’s Beatriz Corredor refuted this, emphasizing ample supply and low demand at the time. Reuters Critics argue that slow progress on European grid integration may exacerbate such risks, while others caution against politicizing the outage without evidence. The reported deaths of at least eight people—seven in Spain from candle fires or generator fumes and one in Portugal due to a ventilator failure—underscore the human cost.

Spain’s resilience in crises is reflected in its history, notably the Alhambra in Granada, a 13th-century Moorish palace and UNESCO World Heritage Site. Its intricate designs and gardens symbolize Spain’s multicultural past, offering a reminder of the nation’s ability to adapt and endure, much like its response to modern challenges like the blackout. UNESCO
Conclusion
The Spain-Portugal joint committee marks a proactive step toward understanding and preventing future blackouts, but the cause of the April 2025 outage remains elusive. As investigations explore grid failures, cyber threats, and renewable energy’s role, the incident highlights the fragility of modern infrastructure. With millions affected and lives lost, the urgency for answers and robust solutions is clear, set against Spain’s storied history of overcoming adversity.
