Spanish Minister says private power companies slow to share information about blackouts

Sara Aagesen, Spain's Minister of Energy, urged private electric companies to share information faster to determine the cause of the worst blackout ever to strike Spain and Portugal.

The cause of the power outage that left 60 million people without electricity in two European countries has not been determined, and the blame-game has increased.

Aagesen, who was in Nice, France for a U.N. Conference, told reporters that information arrived quickly at first. "Now, information is arriving in bits and pieces much slower."

She admitted that the information needed was more detailed, and at times more complex.

She said, "But I insist. I continue to ask for this information as soon as possible to identify the causes and to implement the necessary steps."

The Spanish energy ministry leads one of the investigations into the events that took place on April 28, which sent investigators, from Spain's cybersecurity and Intelligence services, to the premises of private energy companies to gather information.

A spokesperson for the energy ministry declined to comment on what Aagesen meant.

Aelec, the lobby group for Spain's major electricity companies, including Iberdrola, Endesa, and other utilities, has not responded to our request for comment.

Last week it was reported that private companies were cooperating in the investigations.

It said that "it is absolutely false" that the government was withholding or delaying information in response to inquiries about the recent blackout.

PROBES and Finger-Pointing

A Spanish court is also investigating the possibility that a cyber-attack was responsible for the blackout. Separate investigations are being conducted by Spanish legislators.

Red Electrica, the Spanish grid operator, insists that the transmission grid they manage was operating without any problems before the blackout.

Beatriz Corredor (chairwoman of Redeia's parent company) blamed last week some conventional power plants (including nuclear, combined cycle and hydroelectric plants) for failing to maintain an appropriate voltage in the power system on that day. Corredor did not say that this was the cause of the blackout.

Investigators examine excessive voltage in the grid as a possible cause of the loss of production.

Aelec claimed that Corredor's remarks caused confusion and prevented an objective technical assessment. Reporting by Pietro Lombardi. Edited by Aislinn laing and Emelia sithole-Matarise.
