Blackouts across several states caused by fire at Brazil's power substation

An early morning fire at a substation of Brazilian company Eletrobras caused a power outage in several parts of Brazil. Officials said that the shutdown affected more than one million Brazilians and around 10,000 megawatts of load. OnS, Brazil's energy operator, said that the incident took place in a reactor of a substation located in the south. It shut down the facility, and caused the disconnection for the entire region. The region was exporting 5,000MW to the rest of Brazil. The fire in the South resulted to a loss of 1,600 MW. In other areas, an automatic protection system was activated to cut the power when a disturbance caused the system to need to be rebalanced.

The Northeast region was affected by an interruption of approximately 1,900MW. The North region suffered an interruption of 1,600MW. And the Southeast region was affected by 4,800MW.

Brazil Mines Minister Alexandre Silveira described the blackout as an isolated incident that was not caused by a lack in energy but an issue with infrastructure.

"We now have greater energy safety." "This was an isolated incident to which ONS responded promptly," Silveira stated during an interview with local television.

ONS reported that the equipment was restored and the loads recovered "safely" within the first minutes. All the loads were returned within two-and-a half hours.

Eletrobras stated in a press release that it would work with ONS in order to identify the cause of the incident, and the agency will also investigate the factors leading to the wider disturbance in the interconnected national system.

The blackout affected at least 1.3 millions people, according to electricity distributors in the country. These include Light and Enel Sao Paulo. (Reporting by Leticia Fucuchima in Sao Paulo and Rodrigo Viga Gaier in Rio de Janeiro; Writing by Fernando Cardoso; Editing by David Gregorio)
