System dynamics: análise da viabilidade econômica da co-geração de energia com a utilização do bagaço de cana-de-açúcar. Revista Anhangüera, Goiânia, v. 10, n. 1, p. 29-46, jan./dez. 2009.e- 1519-423Xhttp://repositorio.bc.ufg.br/handle/ri/17664This article aims to analyze the economic viability of cogeneration of energy in a sugar-alcohol industry using sugar cane bagasse through the application of system dynamics methodology. In the analysis was used data from the study of Esperancini & Nagaoka (2006), which addressed the feasibility of cogeneration from another point of view. It is concluded that considering the size and characteristics of the investment it becomes more attractive economically if is used capital originated from outside sources. This is because the minimum price to be received by energy should be at least R$ 54.63 MW to justify a investment, using a combination of 20% of own resources and 80% of resources funded.porAcesso AbertoInvestimentoEnergia elétricaIndústria sucroalcoleiraInvestmentElectricitySugar cane industryArtigo
