Spain’s Energy Minister Sara Aagesen revealed that the April 28 blackout originated in Granada, Badajoz, and Sevilla, likely triggered by overvoltage. Initial findings show cascading disconnections and no evidence of a cyberattack.
Spain’s energy minister confirms a third grid disturbance occurred just 19 seconds before the April 28 blackout that affected Spain, Portugal, and southern France.
Spain’s recent blackout slashed digital purchases by 55%, causing an estimated €400 million loss. While partial recovery is underway, the total economic impact could reach €800 million, according to Economy Minister Carlos Cuerpo.
At least five people died in Spain following the massive blackout that hit the Iberian Peninsula on Monday. Authorities confirmed the power grid was fully restored by Tuesday morning.
Portugal will establish an independent commission and demand an EU audit of the Iberian power grid, holding Spain responsible for the blackout that disrupted both countries.
Authorities are investigating whether cybercriminals were behind the massive power outages that affected millions in Spain, Portugal, and parts of France. If confirmed, it would be the largest cyberattack against energy infrastructure since Ukraine’s BlackEnergy incident in 2015.
