A problem with the European electricity grid is causing traffic lights and transportation disruptions in Spain and Portugal, according to a statement from E-Redes

The traffic lights are off in Portugal, alongside the metro in Lisbon and Porto being shut down, according to the police. A statement from E-Redes was seen by The New York Times and says that Spain and France were affected by a problem in the European electricity grid. The Basque Coast and the Burgundy region were affected by the outages, according to the supplier.

Power went down Monday afternoon in vast areas of Spain, crossing over into Portugal and France causing widespread outages in homes and businesses and bringing transportation infrastructure to a halt. The cause of the malfunction is not known at this time. Several cities are said to be affected. The outage started at around noon.

A graph on Spain’s electricity network website showing demand across the country indicated a steep drop around 12:15 p.m. from 27,500MW to near 15,000MW.

Spain’s electricity network operator said it would be restoring electricity to the north and south of the peninsula over the next few hours.

Expresso reported that E-Redes said there was a problem with the European electricity system. The company said that it had to cut power in certain areas to make sure the network was stable.

Play has been suspended at the Madrid Open tennis tournament, according to Sky News. Madrid’s underground rail system has reportedly been evacuated and traffic lights in the city aren’t operating. Air traffic in Spain and Portugal is also reportedly affected by outages at area airports, with Spanish airport operator Aena saying on X that backup generators are currently active at impacted airports. Emergency services in Madrid are still running on generators.
