Espera-se que a gera??o de energia e?lica aumente significativamente no futuro pr?ximo. Nos ?ltimos anos, a energia e?lica cresceu de um pequeno nicho na ?rea de eletricidade para uma fonte bem estabelecida de produ??o de eletricidade em muitos pa?ses. As predi??es preveem um forte aumento no desenvolvimento da energia e?lica nos pr?ximos 15-20 anos. Grande parte desse desenvolvimento ser? de energia e?lica offshore. Isso implica que um grande investimento ser? feito em parques e?licos offshore nas pr?ximas d?cadas. Por esta raz?o, os parques e?licos offshore prometem tornar-se uma importante fonte de energia no futuro pr?ximo. O objetivo deste trabalho ? apresentar um estudo estimativo b?sico para implanta??o de turbinas e?licas offshore no litoral do Rio Grande do Norte, atrav?s de um estudo de caso no munic?pio de S?o Miguel do Gostoso. O Brasil possui um grande litoral, com aproximadamente 3,6 milh?es de km? na sua Zona Econ?mica Exclusiva, ?rea que pode ser aproveitada para a gera??o de energia e?lica offshore. Os dados de vento para se realizar a an?lise foram obtidos do projeto MERRA (Modern- Era Retrospective Analysis for Research and Applications), em sua vers?o 2, denominada de MERRA-2, que ? um modelo de mesoescala para gera??o de dados de longo prazo de rean?lise global, disponibilizado pela NASA. Para o c?lculo da gera??o de energia tomou-se um intervalo de 3 anos (01/05/2014 a 01/05/2017) de uma s?rie hor?ria de velocidade de vento a 50m de altura, escolhidos nas coordenadas S 5.000000 W 35.625000, regi?o mar?tima no litoral de S?o Miguel do Gostoso. Atrav?s da lei de pot?ncia, esta velocidade do vento foi extrapolada para as alturas de cubo de 3 modelos de aerogeradores escolhidos para a an?lise. Foi calculado a distribui??o de frequ?ncia de Weibull e a produ??o anual de energia. O resultado apresenta que entre os tr?s aerogeradores de 5 MW analisados, o que se mostrou mais adequado a instala??o, de acordo com as condi??es levantadas foi o aerogerador offshore Gamesa G132. / Wind energy, as a renewable source of energy, produces no emissions and is an excellent alternative in environmental terms. Wind power generation is expected to increase significantly in the near future. Over the last years, wind energy has grown from a small niche in the electricity area to a well-established source of electricity production in many countries. Estimates predict a strong increase in wind power development over the next 15-20 years. Much of this development will be offshore wind power. This implies that great investment will be done in offshore wind farms over the next decades. For this reason, offshore wind farms promise to become an important source of energy in the near future. The purpose of this work is to present a basic estimative study for the implementation of offshore wind turbines in the coast of Rio Grande do Norte, through a case study in the municipality of S?o Miguel do Gostoso. Brazil has a large coastline, with approximately 3.6 million km? in its Exclusive Economic Zone, an area that can be used to generate offshore wind energy. The wind data for the analysis were obtained from the MERRA project (Modern-Era Retrospective Analysis for Research and Applications) in its version 2, denominated of MERRA-2, that is a model of mesoscale for generation of data of long-term of global reanalysis, made available by NASA. For the calculation of energy generation it was taken an interval of 3 years (From 1st may 2014 to 1st may 2017) from a time series of wind velocity at 50m height, chosen at coordinates S 5.000000 W 35.625000, a maritime region on the coast of S?o Miguel do Gostoso. Through the power law, that wind velocity was extrapolated to the cube heights of 3 wind turbine models chosen for analysis. Weibull frequency distribution and annual energy production were calculated. The result shows that among the three wind turbines of 5 MW analyzed, which proved to be more appropriate to the installation, according to the conditions raised was the offshore wind turbine Gamesa G132.
