Santa Inácio’s initial investment in power generation equipment was amortized within two years through income from electricity sales. The majority of the equipment needed - including a power substation, frequency converter, and process automation for sugar and alcohol production – was supplied by Siemens. Siemens even developed a steam turbine now widely used in Brazil specifically for this application in sugar factories, and it was able to cut the turbine’s price compared with alternative models by 30 percent.”
South Africa has the expertise to manage the alternative solutions.
