The goal of the construction of the Piracicaba substation is to connect the local grid to the national grid as part of a wider objective to improve the reliability of electricity services in Brazil. The facility is a step-down substation, meaning that it is designed to connect the 440kV high voltage transmission lines to the low voltage 138kV local grid. The substation is composed of two sectors: i) the first sector, or step, is the 440kV input lines into the substation and ii) the second sector, or step, is 138kV input lines into the local grid. As in all energy projects in Brazil, the goal of the partnership with the private sector is to further improve the reliability of the electricity grid by benefiting from the private sector expertise and transferring the construction risk to the Project Company.
