Spain Prime Minister Pedro Sánchez ruled out on Tuesday (29), the possibility of an excess of electricity generated by renewable sources caused the huge blackout that hit the Iberian Peninsula the day before.
Sánchez told reporters that technicians were still trying to find out the precise cause of the collapse and that the results of the investigations would be used to reinforce the system.
“What happened yesterday can’t happen again,” he added.
Although a preliminary evaluation of the Spanish network operator Ree ruled out a cyber attack, Sánchez commented that the country’s cyber security authorities were conducting a separate investigation into this possibility.
Blackout
Around 12:30 pm in Madrid and 11:30 am in Lisbon, there were cuts of energy in much of the Iberian Peninsula.
Basque regions were briefly affected, but not for long.
Interruptions affected trains, subway lines and international airports in both countries.
Spanish electric power supplier Red Electric, said that the restoration of energy supply to all customers can take six to ten hours, in statements to a local broadcaster on Monday.
Spanish authorities have asked people to minimize their movements and call emergency services only in extreme emergency cases.
They also asked people to stay away from the roads so that rescuers can trigger the system.
Portuguese police warned that traffic lights and street lighting are at risk of failures, asking drivers to avoid unnecessary displacements and pay extra attention to the roads.
Portuguese airline Tap Air also requested that travelers will not move to the airport.
