    The present work is focused on determining the wind potential from the energy resource which is generated by the wind, with the possibility of installing high-power wind turbines, in the Mechahuasca sector in Pilahuín Parish, Canton Ambato, Tungurahua Province. The research is of experimental type based on the analytical method, with the aim of evaluating variables of wind like: average speed and predominant direction, the one was taken from a meteorological tower inside the ecological reserve Chimborazo, the tower delivered data to 30 meters The data is analyzed statistically by software such as Excel and SPSS, extrapolating this data to 90 meters which is the location of the hub of a high-power wind turbine, obtaining as a result a power density of 547.5 W/m2 with a predominant direction of the East and an average speed of 7.36 m/s, these results were important for the selection of the wind turbine, since according to the IEC 61400- 1 standard, we must select the agreement at the annual average speed and the turbulence index, a wind turbine of class III or IV type A, therefore a model is selected (GW82/1500) that met the required ranges, with important characteristics such as the swept area that is 5320 m2, with a nominal power of 1500 kW, while the wind potential that would be produced anually by the wind turbine is of 2912.7 kW, finally this will cover 10% of the energy demand of the province of Bolivar that is (8,532 GWh). In conclusion, the Mechahuasca sector is not an area that can be used for the implementation of high-power wind turbines, since these must have a range above 1000 W/m2, in addition only the wind energy could be used in some summer months. However, this analysis would be useful for medium-scale turbine implementation studies, which do not present obstacles on the site that interfere with wind speed and direction, considering it a dry grass area, with an average turbulence index between 0,1 to 0,2.
