A power outage hit several areas of the Spanish island of La Palma in the Canary archipelago on Thursday, the local council said in a post on the social media platform X.

Spain’s high-voltage electricity grid suffered more power generation disruptions than previously known ahead of the country’s largest ever blackout, the government said.

Spain experienced a widespread power outage that left millions without electricity for nearly a full 24 hours. While power has largely been restored, the cause of the failure is still under investigation.
