The Spanish National Court has classified the investigation into a massive power outage on Monday as secret. This decision aims to prevent any actions that could jeopardize the investigation’s outcome. The court indicated that cyber terrorism is among potential causes for the blackout, which significantly disrupted essential services.

Judge José Luis Calama opened the inquiry at the request of the public prosecutor’s office, underscoring the importance of maintaining confidentiality during the early stages. The judge emphasized that the release of information could allow for interference with the investigation’s objectives.

The outage occurred at around twelve-thirty in the afternoon when fifteen gigawatts of energy vanished within five seconds, which equates to sixty percent of total consumption at the time. The event has raised serious concerns regarding the security of vital infrastructure, affecting healthcare, energy supply, industry, and transportation.

As part of the inquiry, Judge Calama has asked the National Cryptologic Centre and Red Eléctrica to submit reports within ten days detailing the causes of the blackout. Additionally, the police information unit has been instructed to provide a preliminary report on the situation experienced nationwide. If cyber terrorism is confirmed, it may fall under terrorism offences as defined by Spanish law.
