This work evaluates the electric power potential of the Brazilian sugarcane industry using the biogas produced by vinasse biodigestion in internal combustion engine driven generators. The electric power surplus based on crop 2004/05 ethanol production data is 9,292 TJ/year (2.6 TWh/year), 0.75% of the total electric power consumption in Brazil during the year of 2003. In spite of its considerable potential the determined minimum selling price for its produced energy of R$ 89.98/GJ (R$ 323.92/MWh) is expensive for present Brazilian electric power market price.
