A massive power outage swept across the Iberian Peninsula, affecting millions in Spain, Portugal, Andorra, and parts of southwestern France. The blackout disrupted transportation, communication, and essential services, prompting investigations into its cause and raising concerns about the resilience of Europe's power infrastructure. (2025 European power outage)
At approximately 12:33 PM Central European Summer Time (CEST), the lights went out across vast regions of the Iberian Peninsula. The sudden loss of electricity affected major urban centers, including Madrid, Lisbon, and Barcelona, leaving millions without power. (2025 European power outage)
Transportation systems ground to a halt. In Spain, all trains were stopped, and metro lines were evacuated due to signaling failures. Traffic lights ceased functioning, leading to gridlock and accidents in several cities. Airports, including Lisbon Airport, faced operational challenges, with flights delayed or canceled.

In Portugal, the blackout disrupted mobile networks, limiting voice calls and data services. Hospitals switched to backup generators to maintain critical operations. The Lisbon Metro was halted, and commuter rail services were suspended. (2025 European power outage)
The cause of the blackout remains under investigation. Initial reports suggested a fire in southern France between Perpignan and Narbonne might have damaged an extra-high-voltage power line. However, France's Réseau de Transport d'Électricité (RTE) dismissed this theory, stating no fires were reported in the area. (2025 European power outage)
Spain's cybersecurity agency, INCIBE, is exploring the possibility of a cyberattack, though preliminary analyses have not found evidence supporting this scenario. The Spanish electrical operator, Red Eléctrica de España (REE), described the outage as "exceptional and totally extraordinary," estimating that full restoration could take between six and ten hours.

Portugal's network operator, Redes Energéticas Nacionais (REN), indicated that operations might take up to a week to return to normal, highlighting the severity of the disruption. (2025 European power outage)
The blackout's impact was profound. Residents were left without heating or air conditioning, depending on the region's needs. Businesses closed, and schools dismissed students early. Supermarkets faced challenges preserving perishable goods, and water supply systems experienced pressure due to pump failures.
Emergency services were stretched thin, responding to increased incidents resulting from the blackout, including traffic accidents and medical emergencies. The lack of communication further complicated coordination efforts.
Governments in the affected countries convened emergency meetings to assess the situation and coordinate responses. Spain's Prime Minister addressed the nation, assuring citizens that efforts were underway to restore power and investigate the cause.
Portugal's cabinet, led by Prime Minister Luis Montenegro, held an emergency meeting to address the crisis. Additional police were deployed to manage traffic and maintain public order. (2025 European power outage)
The European Union expressed solidarity with the affected nations and offered support in investigating the incident and strengthening the continent's power infrastructure.
By the evening of April 28, power began returning to some areas. REE and REN worked tirelessly to restore electricity, prioritizing critical infrastructure such as hospitals and water treatment facilities.
As of April 29, electricity has been fully restored in Portugal. Spain and parts of southwestern France continue to experience intermittent outages, with efforts ongoing to stabilize the grid.
This blackout underscores the vulnerabilities in Europe's interconnected power grid. As nations increasingly rely on shared infrastructure, disruptions in one area can have cascading effects across borders.
Experts emphasize the need for robust cybersecurity measures, diversified energy sources, and modernized infrastructure to prevent future incidents. The blackout serves as a wake-up call for policymakers to invest in resilient energy systems capable of withstanding both physical and cyber threats.
The April 28 blackout was one of the most significant power outages in recent European history, affecting millions and disrupting daily life across the Iberian Peninsula. While investigations continue, the incident highlights the critical importance of resilient and secure energy infrastructure in an increasingly interconnected world. (2025 European power outage)
