In Spain and Portugal, they are restoring power supply and searching for the cause of the massive blackout

After a massive blackout that plunged the Iberian Peninsula into darkness on Monday, Spain is rapidly restoring power supply. According to the national grid operator Red Eléctrica de España (REE), by 4 am on Tuesday, electricity had been restored to 87.37% of the mainland territory.

The previous evening, Prime Minister Pedro Sanchez delivered a televised address, reporting that power supply had been restored by half. "The task is to continue restoring supply in the coming hours," emphasized the head of government. However, he did not specify exact timelines for full system recovery and warned that some workers would have to stay home on Tuesday.

The exact cause of the massive power outage affecting Spain and Portugal remains a mystery. Portuguese Prime Minister Luis Montenegro stated that the source of the problem "is probably located in Spain." In turn, Sanchez noted that authorities are thoroughly examining all versions.

"All possible causes are being analyzed, I emphasize, no hypothesis, no possibility is being ruled out," said the Spanish prime minister.

The outage began shortly after noon on Monday, affecting cities across the mainland. The Balearic and Canary Islands were not affected. According to Sanchez, about 15 gigawatts of electricity - more than half of the power being consumed at that moment - "suddenly disappeared" within five seconds.

Portuguese authorities put forward a theory about a rare atmospheric phenomenon related to temperature fluctuations. Portuguese energy company REN reported that the disruptions were the result of "a malfunction in the Spanish power grid" and explained: "Due to sharp temperature fluctuations in central Spain, abnormal oscillations occurred on ultra-high voltage lines (400 kV) - a phenomenon known as 'induced atmospheric vibrations.'"

European Council President António Costa assured that there are currently no signs of a cyberattack.

In Madrid, many businesses, shops, and restaurants were plunged into darkness. Internet service was cut off in many places. Due to non-functioning traffic lights, traffic jams formed in the center of the Spanish capital.

Spanish national railway company Renfe reported that at 12:30 local time, "the entire national power grid of the country was disconnected." "Trains stopped" and "were not departing" at all stations. Met
