Grid Solutions has signed a deal with Casa dos Ventos to construct two 500 kV air-insulated substations (AIS) for the 756 MW Serra do Tigre Wind Complex in Brazil. The project is located in the municipalities of Currais Novos and Sao Tome in the state of Rio Grande do Norte.
Grid Solutions will supply two greenfield substations, Tigre Norte 2x 280 MVA and Tigre Sul 2x 220 MVA, and will also install a connection bay at the Santa Luzia substation. The necessary high-voltage equipment, protection and control system, and telecom system will also be provided.
To ensure the safety, reliability, and efficiency of the 500 kV AIS, the National Electrical System Operator (ONS) and National Electric Energy Agency (ANEEL) have set forth a set of rigorous technical requirements. Both Grid Solutions' substations are expected to be energized by the end of 2024, with the wind machinery at the Serra do Tigre Wind Complex gradually undergoing testing thereafter.
