paragraph_text: On Monday, 28 April 2025, at 12:33 CEST (11:33 WEST; 10:33 UTC), a major power blackout occurred across the Iberian Peninsula affecting mainland Portugal and peninsular Spain, where electric power was interrupted for about ten hours in most of the Peninsula and longer in some areas. The power cut caused severe difficulties in telecommunications, transportation systems, and essential sectors such as emergency services. At least seven people in Spain and one in Portugal may have died due to outage-related circumstances like candle fires or generator exhaust fumes. The total disconnected load can be estimated at 30 GW.
  
  Minor power cuts lasting seconds or minutes occurred in adjacent regions of Andorra and parts of southwestern France. Reports indicated problems with the European synchronous electricity grid. Traffic lights in many places stopped working, and metro lines had to be evacuated.
