Английская Википедия:2009 Brazil and Paraguay blackout
The 2009 Brazil and Paraguay blackout was a power outage that occurred throughout much of Brazil and for a short time the entirety of Paraguay,[1] on Tuesday, November 10, to Friday, 20 November, 2009, at approximately 22:15 BST.[2] The blackout affected an estimated 60 million people in Brazil.[3]
Description
Thousands of passengers were stranded as metro trains came to a halt and buses failed to cope with the volume of passengers. There were widespread reports of road accidents as street lighting and traffic lights failed.[4] The blackout began about 22:15 on Tuesday and lasted until about 02:45 on Wednesday in São Paulo, although power was restored gradually in some places from before midnight.[5][6]
Causes
Heavy rains and strong winds caused three transformers on a key high-voltage transmission line to short circuit, cutting the line and automatically causing the complete loss of 14 GW of power and the shutdown of the Itaipu Dam for the first time in its 25-year history.[7][8] The power cut, which Brazilian officials said affected 18 of the country's 26 states, brought chaos to cities including São Paulo, Rio de Janeiro, Belo Horizonte, Campo Grande and Vitória.[9]
Media such as Slashdot[10] and 60 Minutes reported[11] that the outage was the work of hackers. However, in December, 2010, a leaked US diplomatic cable suggested otherwise and indicated that the longest outage was 6 hours, in São Paulo, and details interim reports on what failures caused the outage, and responses under consideration.[11]
President Luiz Inácio Lula da Silva arranged an emergency commission to enquire into the cause of the blackout.[12] The blackout also unleashed a political stir as the Minister of Energy has been summoned to testify before Congress.[13]
Affected regions
Paraguay
The Itaipu Dam is shared with Paraguay. In the immediate aftermath of its failure, interconnecting lines to Paraguay's other large powerplant, the Yacyreta Dam (in the border with Argentina), also failed. All of the country's territory was affected by the blackout.[14][15]
