Spain Urges Power Companies to Publish Data After April Blackout InvestigationGovernment Response and Investigation DetailsCall for Transparency from Power CompaniesMADRID, March 23 (Reuters) - Spain's Energy Minister Sara Aagesen on Monday called on power companies to make public all the information they have related to the massive blackout that hit Spain and Portugal last April to ensure a fully transparent investigation of its root causes. Investigation FindingsWhile they all point to a surge in voltage as the immediate cause, no report has assigned blame and the information provided by companies was cited as anonymous. Statements from Energy Minister Sara AagesenRequest for Public Disclosure"I take this opportunity to ask companies, since this information (about the outage) is available to them, to please make it public," Aagesen told a Senate committee hearing. "With the existing regulatory elements and mechanisms, the blackout should not have happened," Aagesen said. Future Outlook and Renewable Energy IntegrationThe Spanish power system is now better prepared to tackle a similar event, she said, adding that the country can keep adding renewable power sources with no risk of another massive blackout.
