The National Court will investigate the blackout, although Red Eléctrica rules out sabotage.

MadridAlthough Red Eléctrica ruled out a cyberattack as the cause of the power outage, the National Court decided to investigate. Judge José Luis Calama agreed to open preliminary proceedings to clarify what exactly happened on Monday and thus verify the "computer sabotage" hypothesis. The hypothesis is unknown, and that "cyberterrorism is among the possible causes." Therefore, in the opinion of the National Court judge, a judicial investigation is necessary. "In order to find out, Calama has requested three reports on the cause that led to the sudden loss of 15 gigawatts, or 60% of Spain's electricity production, in just five seconds: at the National Cryptologic Center, at Red Eléctrica, and at the National Cryptologic Center. "We must not issue, even if only preliminarily, within the non-extendable period of ten days," he states.

Sánchez: "No hypothesis should be ruled out."

Spanish Prime Minister Pedro Sánchez has stated that "no hypothesis should be ruled out," although for the moment "there is no conclusive information that a terrorist attack was the cause of the blackout." The Prime Minister expressed the Spanish government's intention to promote an "independent analysis" of the causes, which, he guaranteed, will be presented to the public. "It will take as long as necessary," he said, to be "accurate." Regarding the National Court's investigation, Sánchez stated: "It is part of the logical order of things in a democratic state like ours."
