We can conclude that there has been no kind of intrusion into our control systems, says Red Eléctrica's highest chief Eduardo Prieto at a press conference, according to Spanish media.
Nor is there any information in Portugal that it was about a cyberattack, says government spokesperson Antonio Leitão Amaro.
There is still no answer to why the power went out in almost all of Spain and in several neighboring countries in Monday's massive outage. At 12:33, the mobile network, airports, local traffic, traffic lights, and shopping centers were down simultaneously.
Unclear cause
Spain is setting up an investigation to examine the massive power outage.
All necessary measures will be taken to ensure that this does not happen again, says Prime Minister Pedro Sánchez at a press conference on Tuesday.
The power has returned to "99.5 percent" in Spain, according to Sánchez. Even in Portugal, everything is reported to be working normally again.
The work of getting the power back took time – even ten hours after the outage, half of Spanish households, and two-thirds of Portuguese households, were without electricity.
There is no mobile coverage, I cannot call my family, my parents, nothing. I cannot even go to work, said Carlos Candori, a 19-year-old construction worker who had taken himself out from the subway in Madrid.
The power outage is the largest in Spanish history. When there was no explanation in the first stage, many rumors and much misinformation flourished.
Demands for a state of emergency
Both EU Council President António Costa and the Spanish Vice-President of the EU Commission, Teresa Ribera, have previously said that there is no evidence that a cyberattack caused the outage.
According to the Spanish rescue service, 35,000 people were helped during the outage, who were stuck at different train stations and subway lines.
Three regions – Andalusia, Extremadura, and Madrid – requested that a state of emergency be declared there.
30,000 police officers were deployed to make Spain safer during the night.
