Spain’s national transmission system operator has not found signs that a cyberattack was at the root of the massive power blackout in Spain and Portugal on Monday.
“With the analyses we have been able to carry out so far, we can rule out a cybersecurity incident in the electricity grid facilities at the Red Eléctrica control center,” Red Eléctrica’s head of system operation services Eduardo Prieto said at a press conference on Tuesday.
Prieto said the conclusions were preliminary, but said that so far, the operator had “been able to conclude that there has not been any type of intrusion in the electrical network control systems that could have caused the incident.”
