Argentina’s energy secretary says improper reprogramming of the electricity system following the installation of a bypass on a major transmission line caused the power outage that left tens of millions of people in three nations without power.
Argentina has opened an inquiry into what caused a massive blackout that left nearly 50 million people without power, Energy Minister Gustavo Lopetegui said on Monday.
A massive blackout left tens of millions of people without electricity in Argentina, Uruguay, Paraguay and parts of Chile and southern Brazil on Sunday. The Argentine president called it an “unprecedented” failure in the countries' interconnected power grid.
Argentina's Energy Secretary Gustavo Lopetegui described the massive blackout suffered mostly by Argentina and Uruguay, but which also affected areas of neighbouring countries, Paraguay, Chile and Brazil as “an extraordinary event that should have never happened, there are no reasons for it occurring and leaving Argentina completely in the black”.
