This paper reported an analysis for an energy integration of a Sugar Mill of a milling capacity of 6900 t/d of cane, an alcohol distillery of 500 Hl/d and a Single Cell Protein plant of 10 t/d is performed becoming a Bio refinery complex. All based on an option in which sugar mill supplies steam and electricity to satisfy needs of each plant during season and ensuring- at this time–enough surplus bagasse and straw, to cogenerate and satisfy steam and electricity demands of annexed plants in off season period. This way it was proven that a sugar mill could satisfy energy demands of these plants and also deliver 6,85 MW-h to national grid during milling season. In addition, 1054 t/d of surplus bagasse was obtained, that together with collected straw from cane harvesting , guaranty complex energy demand, for operating 100 days in off season , at designed production levels of all installations and delivering a surplus of 14,18 MW-h to national grid. With energy integration, Sugar Mill-Distillery-Single Cell Protein (SCP) plant production costs are reduced, because of saving energy consumption, in addition of eliminating all related emissions and environment impacts. A total cost saving gets US $ 3,065,385.00 CUC at harvest season. In addition to this an additional income to milling enterprise is added by selling electric energy to national grid (price to be determined by contract)
