The ventures were defined in the Planning Estatutes of the Energy Research Company (EPE). The commercial operation start period is of 18 months from the concession contract signing, which is of 30 years.

The transmission installations to be bidded were dimensioned by EPE based on the demand by connection of the Interconected System of the 27 allowed generator central in a public call (see here the result) held by Aneel last July. The aim of the auction is to make the energy produced by these two ventures flow, which totalizes approximately 2 thousand megawatts (MW) and it is expected they be operational within July 2010 and December 2013. These plants participated of the first reserve power auction last 14^th august.
