Wind power has gained space in Brazil’s energy matrix, being a clean and inexhaustible source. The wind speed data were collected by Wind Set WA25 anemometer from Vaisala Company, installed in a tower at 10 m from ground at the Automatic Weather Station belonging to Meteorological National Institute, located at School farm of IF Goiano, Iporá-GO. The wind speed variability was represented by the Weibull frequency distribution, a probability density function of two parameters (k e c). We used the parameters k e c, to correlate the Gamma function with the annual average wind speed, the variance and power mean density. We made a wind profile to evaluate the behavior of historical average speeds at higher altitudes which the measured by anemometer, to estimate the gain in power density. The values of k for all heights were close to 1 which corresponds to a wind regime highly variable, and c values were also low representing a low average speed of the local. The location was characterized as being unfavorable for the application of decentralized wind turbines for power generation.
