Brazil is at the moment in a phase of intensive construction activities in the sector of hydroelectric power plants.
The project is located on the Sapucai River in Sao Paulo state. The client CPFL is a privatised power utility. The project includes the total renovation of two existing power stations. The old generating units is replaced by completely new, modern units with increased output. The necessary civil works are carried out in a consortium with Camargo Correa as partner company, the overall engineering being done by the Brazilian engineering company Intertechne.
For Sao Joaquim, which has even less head (17 m), three CAT turbines with a unit output of 3 MW acc. to the standard series of VA TECH HYDRO turned out to be the optimal solution. CAT stands for Compact Axial Turbine, the concept of which is similar to a classical S type turbine but is more compact due to lower setting of the runner. The CAT turbines will be preassembled in the workshop and delivered to site in assembled state. Thus, installation time will be reduced to a minimum.
