The decision kick-starts new power-planning policies announced in July that aim to eradicate grid connection delays by auctioning transmission lines ahead of, or close to, the auction of wind power projects.
The lack of synchronisation between lines and wind farms has raised developers' costs and left 1GW of Brazilian wind capacity unconnected in the past two years.
The December auctions are for the Coxilha de Santana, Escudo Rio-Grandense, Litoral Sul and Costa da Lagoa dos Patos areas, which are due to come on line in 2018.
