Spanish court seals part of blackout investigation

Spain’s National Court has classified part of the investigation into the massive blackout that affected nearly the entire Iberian Peninsula on April 28.

Thus, Judge José Luis Calama, at the request of the prosecution, ordered certain details of the investigation to be kept confidential, Caliber.Az reports per foreign media.

The blackout, which occurred on April 28, left a significant impact across Spain, with authorities now looking into whether the power failure could have been the result of a cyber-sabotage targeting critical infrastructure.

In the ruling, Judge Calama explained that the secrecy of the investigation is intended to prevent potential leaks of sensitive information, which could jeopardise national security and interfere with the ongoing probe.

The court emphasized that safeguarding these details is crucial for maintaining the integrity of the investigation.

The incident has raised concerns over the vulnerability of Spain’s energy systems and the potential risks posed by cyberattacks on critical infrastructure.

To recall, on April 28, 2025, Spain and Portugal experienced one of Europe's most severe power outages, affecting over 60 million people. The blackout began at 12:33 CEST, impacting major cities like Madrid and Lisbon, and extending to parts of southern France.

The outage disrupted transportation, healthcare, and telecommunications, with train services halted and airports operating at reduced capacity. In Spain, nuclear reactors were automatically disconnected from the grid, and backup generators maintained cooling systems.

The economic losses were estimated between €1.6 billion and €4.5 billion. Authorities have ruled out cyberattacks as the cause, and investigations continue. The event underscores the vulnerabilities in Europe's power infrastructure and the urgent need for resilience measures
