At the same time, federal power companies such as Eletrosul, Furnas and Chesf stayed out of the bidding as they have done since last year.

Brazil contracted 926MW from 36 wind projects in the auction. Total investment in the projects is estimated at R$3.46bn ($1.35bn), an average of R$3.74m per installed megawatt, according to auction organizer, the Brazilian Power Trading Chamber (CCEE).
