Brazilian sugar-cane industry has potential to produce 2-4 GW of power at competitive basis and up to 2-3 times more if financial and environmental incentives are given. About 2.0 GW can,be add to the basic potential considering a carbon offset cost lower than 30 $/t C. Some of the instruments that can be used to deploy this potential are tax credits, loans. project loans guarantees, the creation of green markets and external costs evaluation. Biomass Integrated Gasifier-Combined Cycles (BIG-CC) is the technology considered within the analysis presented in this paper. The results are based on simulations considering cogeneration operation mode during the harvest season aid power plant mode otherwise. The potential was calculated considering the Brazilian sugar-cane production during 1995-96 harvest season (230 million tons).
