LISBON, April 28 (Reuters) - Portuguese grid operator REN RENE.LS said on Monday it had "no information" that the mass power outages that hit the Iberian Peninsula were caused by a cyberattack.

REN board member Joao Conceicao told reporters the operator did not rule out that the blackout was due to a "very large oscillation in the electrical voltages, first in the Spanish system, which then spread to the Portuguese system".

"If it were up to REN, the country would wake up tomorrow with electricity, but unfortunately it's not just REN that counts," he added.
