A Reuters report[1] says that energy authorities in Brazil have approved a plan to bring back daylight saving time, to save electrical energy during a major drought that has hurt hydroelectric power generation[2]. As far as I know authorities have not decided or published details of the plan, such as which states would be involved and dates and times of transitions. However, one English-language report says that DST would not start until after the election period ends on October 27[3]. This is not a done deal, as any change would need approval by President Luiz Inácio Lula da Silva. That being said, Brazil's DST was abolished by Lula's predecessor and political opponent Jair Bolsonaro, and Lula did an informal Twitter poll shortly after his election in which 66% of respondents voted for DST[4], so presumably Lula would favor restoring DST.
