A major power outage hit Spain and Portugal on Monday, shutting down trains, airports and other critical infrastructure and causing disruptions across the two countries. Energy authorities said the outage occurred following a disruption in the European grid.

It was not immediately clear what caused the outage. António Leitão Amaro, the minister of state for the presidency in Portugal, said on national radio that there is no evidence of a cyberattack.

E-Redes, the national energy supplier of Portugal, said “the interruption was due to a problem in the European electricity grid.”

Power authorities said they were working quickly to restore service while it was still daylight.

“Voltage has been recovered in substations in several areas of the north, south and west of the peninsula,” Spain’s national power company, Red Eléctrica, said on X about 3:30 p.m. local time. Its representatives did not respond to questions about the scope of the outage or any potential cause.
