Estudo de viabilidade econômica da ligação de uma usina termelétrica movida à bagaço de cana no sistema elétrico do Paraná

Abstract

This work aimed to a feasibility study of a thermal power generation using sugarcane bagasse in sugarcane mills of Parana State, showing the importance that bioelectricity plays in the Brazilian energy matrix and how it is carried out to generate these mills. The sale of the surplus energy from these generators may occurs in the regulated market or free market. The participation of biomass in electricity auctions in the regulated market has increased, but this contribution could be more significant because the mills still find difficulties to generate and sell higher volumes of electricity. Examples of those difficulties are: the connection to the electrical system, environmental licensing and the investiment required to do it. The methods used to assess the viability of the project were the payback period and the net worth, which are widely used. These methods have favorable results for electricity generation in sugarcane mills, but the economic viability of cogeneration projects is specific to each project, which depends on a huge number of factors.
