RESUMO
Electricity generation in ethanol and sugar mills using bagasse as a fuel in cogeneration process is a traditional practice. In Brazil, since the 1980s mills have evolved to a position of almost self-sufficiency in electricity production, which indicates a strong potential of electricity surplus that can be used as a complement in the electricity national matrix. Such interest for electricity generation from renewable sources got outstanding due to the lack of supply risk and also the mills necessity of technological adaptations. However, even though the potential exists, there are some factors that influence and put in risk a mills decision to invest in electricity surplus generation which must be evaluated, such as energy prices volatility. The objective of this work is to analyze the electricity price setting process generated by sugarcane biomass and negotiated in the Free Agreement Environment (ACL). In this environment, biomass generated electricity can be negotiated among private agents (free consumers and generators). More precisely, the aim is to show how the hydrological risk that is part of the price setting process and of the system physical dispatch affects the price of the biomass electricity in the ACL, given its actual institutional features. To enable that, an electricity biomass artificial market is developed with the aim to capture the main institutional features of ACL. Several simulations are generated by this computational model, which show the negative impact of spot price volatility over the biomass electricity prices in ACL.
