BARCELONA, Spain, May 20 (Xinhua) -- Spain must adapt its electrical grid to reflect the country's evolving energy landscape or risk more large-scale blackouts, Jordi Sole, an energy expert and professor at the University of Barcelona, told Xinhua in an interview on Tuesday.
His warning comes ahead of a Senate vote on Wednesday that could urge the government to launch an independent investigation into the nationwide blackout that affected the country on 28 April. Sole said the root cause of the blackout is the lack of flexibility and stability in Spain's electrical system.
