Estudo de caso da viabilidade econômica na construção de um parque eólico em Pernambuco.

Abstract

Renewable energies are increasingly used in the world. Wind energy, in evidence in this work, together with investments from other sources can reconcile the energy needs of a society, replacing methods that harm the environment, such as fossil fuels. Faced with such relevance and ample opportunities in the wind energy sector, the present work presents a study of the economic viability in the construction of a wind farm in the state of Pernambuco, exposing the main parameters used based on rates of financing and values provided by the manufacturers. Initially a general explanation was made about the mechanism of formation of the winds, factors that influence its regime: roughness, height, etc. As well as the technology used in wind turbines and their control mechanisms. Next, the Brazilian wind potential, together with the installed capacity and the aspects related to each region, is evidenced. Finally, the economic factor in the construction of the wind farm is analyzed, evaluating the costs and the Internal Rate of Return (IRR) of the investment made.
