On the evening of Sunday (October 1), several neighborhoods in the Southwest and South Zones of Rio de Janeiro, including São Conrado, Rocinha, Itanhangá, Barra da Tijuca, and Jacarepaguá, reported widespread power outages. Social media posts indicated that many residents had been without electricity for more than three hours, particularly in areas like Freguesia. The local utility company, Light, attributed the outages to the failure of a transmission cable along the Estrada do Catonho, and crews were deployed to restore power as quickly as possible.
