A massive power outage in Spain and Portugal threw daily life into chaos on Monday.
Public transport systems ground to a halt, flights were delayed, and streets in major cities like Madrid were choked with traffic jams as authorities scrambled to restore electricity.
The sudden Spain blackout also affected critical infrastructure, prompting a swift government response and heightening concerns over Europe’s energy resilience.
The widespread power outage Spain experienced impacted both nations severely, with Spanish electricity transmission operator Red Eléctrica warning that full restoration could take between six to 10 hours.
Meanwhile, Portuguese utility REN confirmed it had activated emergency protocols to restore the electricity supply gradually.
Though the exact cause of the blackout remains unclear, officials have not ruled out the possibility of a cyberattack.
