Spain, Portugal, and parts of southwestern France experienced a widespread power blackout that disrupted public transport, caused significant traffic congestion, delayed flights, and prevented residents from accessing ATMs. Utility operators and authorities worked to restore the electric grid, and investigations into the cause of the outage on Monday are ongoing.

Portuguese Prime Minister Luis Montenegro stated that there was "no indication" of a cyberattack. The Portuguese National Cybersecurity Centre corroborated this, stating there was no evidence suggesting the disruption was due to a cyberattack.

Spain’s Interior Ministry declared a state of emergency Monday evening, with the emergency status applicable in regions that request it. Madrid, Andalusia, and Extremadura have requested the central government to assume control of public order and other critical functions.

In a televised address, Spain’s Prime Minister Pedro Sanchez said there was no conclusive information on the cause of the blackout. He added that interconnections with neighboring France and Morocco had partially restored supply, while “combined cycles and hydroelectric plants throughout the country have also been reactivated, which should allow us to recover the supply across Spain soon.”
