MADRID — A large-scale power outage plunged parts of Spain and Portugal into darkness Monday, disrupting transportation, buisness operations, and essential services. The blackout affected an estimated 58 million people across the iberian Peninsula, prompting investigations into the cause.
The power outage struck around 12:30 p.m. local time, impacting major Spanish cities including Madrid, Barcelona, Seville, and Valencia, as well as the Portuguese capital, Lisbon, according to reports from Reuters and AFP. Airports experienced flight suspensions and delays, while train services were also disrupted. Traffic lights ceased functioning, contributing to transportation chaos. Many businesses, including restaurants and cafes, were forced to close due to payment system failures, and some hospitals faced service disruptions.
REN, Portugal’s national power grid operator, reported that approximately 48 million people in Spain and 10.5 million in Portugal were affected by the blackouts.
Spanish Prime Minister Pedro Sanchez addressed the nation late Monday, stating that “about 50% of the power capacity has been restored.” He added that authorities are ”analyzing potential causes with all homes and possibilities.” Portuguese Prime Minister Luis Montenegru suggested the origin of the disruption was in Spain.
Possible Cause: Atmospheric Vibration
While the Spanish government investigates, REN has suggested that “induction waiting vibration” due to abnormal climate conditions might potentially be to blame. The company theorizes that extreme temperature differences in inland Spain lead to atmospheric vibrations that affected ultra-high-pressure power lines, triggering the widespread outage.
The Guardian reported that while the electricity industry is aware of the potential dangers posed by rapid changes in air temperature, “problems on this level are rare.”
Understanding Induced Atmospheric Vibration
Induced atmospheric vibration refers to atmospheric disturbances caused by external factors such as earthquakes, large explosions, or rapid temperature fluctuations. These vibrations can affect power transmission lines, perhaps causing voltage and frequency instability, and in severe cases, leading to power outages.
