Sharp Power Swings Trigger Major Blackout in Spain, Portugal

Sharp swings in power caused a network outage that left most of Spain and all of Portugal in the dark on Monday, making it the worst blackout in Europe in years.
While some areas across Spain gradually came back online in the afternoon, restoring all supply in the country will take until at least the evening, according to grid operator Red Electrica. The outage was due to sudden changes on the network, known as “oscillations,” said Eduardo Prieto, the company’s director of services, declining to comment further on the causes.
