Spain's Minister calls on power companies to publish blackout data

Sara Aagesen, Spain's energy minister, called on power companies on Monday to "make public" all information they had relating to the massive?"blackout" that struck?Spain and Portugal in April last year to ensure a transparent investigation into its root causes. The April 28 outage, which left parts of the Iberian Peninsula with no power for as long as 16 hours, prompted multiple investigations by both the government and grid operator.

The reports all point out that a sudden surge in voltage is the immediate cause. However, there was no blame assigned and the information provided by the companies was anonymous.

Aagesen said at a Senate hearing: "I would like to ask that companies make this information public, as they have it."

She added, "I think it would be the best for all citizens."

Aagesen said there had not been any warnings of a possible blackout, like "the one that occurred last year" and that there were "sufficient regulatory" and technical mechanisms to prevent it.

Aagesen stated that the blackout would not have occurred if the regulatory elements and mechanisms were in place.

She said that the Spanish power system was now better prepared to handle a similar incident. (Reporting and editing by Pietro Lombardi)
