<b>Abstract.</b> Through the publication of Law no 9.648, dated 27th May 1998, the Brazilian Government has initiated a progressive derregulamentation of the Brazilian electrical sector, trying to prevent the danger of energy shortage, and motivating the access to energy transmission and distribution. Such an action has estimulated the industry to use rejection heat and industrial residues to cogenerate and rationalize the use of energy. The sugarcane industry in Brazil is one which has become well-known for its frequent exploitation of cogeneration. One reason for such a behavior is the constant and increasing national and international demand for hydrated and anyhidrated alcohol. Japungu Agroindustrial S. A. is a very modern and advanced distillery, sensitive to all these incentives. Therefore, it has planned and started an expansion of its cogeneration system looking forward to reaching its energetical self-sufficiency, generating 300 kWh more, and a surplus of 33,616 MWh, during the season and 3600 MWh off-season, both for selling. This work analyzes the present technical conditions of the distillery, and describes in detail, all the modifications to be introduced, the production goals, some conditioning facts of the expansion, discussing at the end situations in which the required investment will bring the expected results.
