Brazil blames fierce storm for massive blackout

Brasilia: A blackout that cast half of Brazil into the dark overnight was caused by a fierce storm that shorted three high-tension transmission lines, the Energy Ministry has said.
But contradictory statements came from an electricity operator responsible for the affected area, and from the state electricity company in neighbouring Paraguay.

An "atmospheric discharge" packing heavy winds, rain and lightning knocked out the lines running from the country`s biggest power plant, the Itaipu hydroelectric facility on the border with Paraguay, Energy Minister Edison Lobao told a news conference yesterday.

A domino effect meant 40 percent of the national energy supply went offline overnight, he said. He was flanked by aides and operators of Brazil`s electricity grid who had held emergency discussions to determine the reason of the outage, which plunged 70 million people -- more than a third of Brazil`s population of 190 million -- into blackness.

"We all arrived at the conclusion that what happened was the result of atmospheric discharges, very strong rain and wind," he told the televised news conference.

"Everything is completely working now," he said. His executive secretary, Marcio Zimmermann, said the southern half of Brazil suffered an "average" three hours without power -- some parts had energy restored within minutes, others took several hours.
