On March 14 , the March 2010 Chile blackout left roughly 15 million people , about 90 % of the population of Chile , without power when a major transformer failed in southern Chile . Power began to be restored within a few hours , and almost all of the country had power by the following day . The outage was apparently not directly related to damage from the major earthquake that hit the country the previous month
