The possibilities of electricity generation in Brazil are analyzed using a computable general equilibrium (CGE) model. The traditional sector of electricity and the remaining of the economy are characterized by a stylized top-down representation as nested CES (constant elasticity of substitution) production functions. The electricity production from sugarcane bagasse is described through a bottom-up activity analysis, with a detailed representation of the required inputs. The hybrid approach in the representation of production increases the credibility of CGE models in the analysis of energy policy as the possible substitution patterns in electricity conversion are based on engineering studies. The obtained model is used to study the effects of the reduction in electricity output by the preexisting sector on prices, production, and income. It is shown that the generation of electricity surpluses by the sugarcane agro-industrial system may ease the economic impacts on the gross domestic product (GDP) of an electrical energy supply crisis.

Keywords : Modelos energia-economia; geração com bagaço; biomassa; equilíbrio geral; complementaridade não-linear.
