Electricity infrastructure is incredibly expensive. If a main transmission line goes down you will have issues both sides of it, one side experiencing sudden increased supply which will raise the frequency which will cause power plants to trip offline. On the other side you will see frequency drops, which will do the same. I do not know what Chiles power production looks like, but it would be a huge challenge for any power network to deal with one of the main lines suddenly dropping out.
