The aim of this study was to evaluate potential of vinasse as an alternative source of electricity generation through the burning of biogas produced by anaerobic digestion process. The stillage residue is a process of producing ethanol; used as fertilizer on farming’s; but with environmental problems of its application. This study was conducted on the basis of theoretical data to calculate the potential for methane generate and energy. Our purpose is to use an up flow anaerobic-UASB to accomplish the digestion of stillage and engines to burn the gas and electric power generation. The paper presents a case study of a distillery with a production of 580 m³ day^-1 ethanol. In Brazil in the harvest 2009/10 would have produced the stillage potential to produce 1.81 billion m3 of methane and 4.070 GWh of energy. Whereas the case study of sugarcane in the interior of Parana; are produced 5;800 m3 day^-1 stillage; with the potential to generate 2.75 MWh of electricity month^-1; which results in a income of US$ 218;586;32 a month. The use of vinasse as a source of energy has great potential energy for Brazil.
