In this paper two cogeneration systems (Biomass steam turbines and biomass gasification combined cycle) were evaluated and compared based on their potential to meet heat and power requirements of sugar/alcohol plants in two regions of Mexico (south eastern and mid western), which are both characterized by higher production rates of sugar cane. In addition, the potential of those systems to produce an electricity surplus was evaluated as a means to generate additional income in terms of co-product credit. The latter was evaluated in order to reduce the total production cost of fuel ethanol and identify a potential electricity surplus for use by local inhabitants. The analysis was performed comparing different scenarios based on the use of the current planted area in these regions to produce ethanol. Biomass integrated gasification combined cycle system was proven as the most advantageous system to meet heating requirements, generating an important amount of electricity with contribution of about 18 % in reduction of the total production cost of ethanol. Moreover, results indicate the potential to strengthen relations between the two regions with higher opportunities to increase incomes, as well as the improvement of added value cane bagasse with off-season electricity generation.
