Portugal and Spain on Alert: New Findings Shed Light on the Massive Blackout That Left the Iberian Peninsula in Darkness

A month after the Iberian blackout that plunged Portugal, Spain, and parts of France into darkness, engineers are beginning to uncover the causes behind this unprecedented event. The incident, which occurred on April 28, was narrowly prevented from spreading across Europe thanks to the swift response of the French electrical grid.

The Mystery Unfolds

Initial investigations suggest that three solar parks in Spain suddenly disconnected from the grid to protect themselves from voltage anomalies that could have destroyed their equipment. This unexpected shutdown may have triggered a cascade effect, leading to the widespread power outage.

Preparedness for the Future

Jorge Liça, a key figure in the investigation, assures that Portugal will be better prepared to handle such incidents in the coming months. While the likelihood of another blackout remains low, the event has underscored the vulnerability of the Iberian Peninsula's electrical infrastructure.

The Role of a Gas Plant

There are indications that the problem might have originated in a gas plant that stopped operating 20 seconds before the blackout. This detail is among the many pieces of the puzzle that engineers are still trying to fit together.

The investigation continues, with experts working tirelessly to ensure such an event does not recur. The incident has sparked a broader discussion on the need for more resilient energy systems in the face of increasing demand and the transition to renewable sources.
