Overview

• A widespread power outage disrupted electricity across the Iberian Peninsula and southern France on April 28, affecting millions and halting essential services.
• Initial investigations suggest the blackout originated from a fault in Spain's transmission network, with no evidence of a cyberattack reported so far.
• Emergency measures included shutting down Spanish nuclear plants and France providing 700 MW of electricity, with capacity to increase to 950 MW if needed.
• Partial power has been restored in several regions, and officials project a full recovery within 6–10 hours if operations proceed smoothly.
• The outage caused significant disruption, including halted train and metro services, darkened streets, and widespread reliance on generators for critical services.
