MADRID: The Spanish National Electricity Grid Operator (REE) announced on Tuesday that its initial analysis has determined that a cyberattack was not responsible for the nationwide power outage experienced across much of Spain and Portugal on Monday.
The incident, which was the most significant blackout ever reported in the Iberian Peninsula, occurred at 12:33 PM local time (10:33 AM GMT). Power was restored later that evening.
Eduardo Prieto, the Chief of System Operations at REE, explained during a press briefing that a severe loss of power generation in southwestern Spain triggered instability within the system, leading to its disconnection from the French electrical network.
Prieto suggested that the lost generation might have been from solar energy, but he noted that it was too early to confirm this.
He reassured the public that the electrical system is now stable and operating normally.
