Wind power is renewable energy that could be transformed into electrical energy through the utilization of a wind turbine mechanical technology which designed for use in the vicinity of the Maehae Sub-district, Samoeng district, Chiang Mai Province. The Maehae area had the potentiality to have enough quantity of wind power to produce electricity and it was sufficient for the people usage in the area. Consequently, this study had been designed for the estimation of the electrical energy storage, and the design of the optimize generator for used in the surrounding area where the selection of the renewable energy source could be performed for the maximum utilization. In short, the permanent magnet generator was designed in the wind turbine for the household average area of 65 m2. According to the research, it was found that the turbine should have a diameter of 2.7 meters and that the energy storage of the battery should be 23.155-53.881 Ah for a wind speed of 9 m/s. The frequency of the generator should be 50 Hz. The permanent magnet installed in the generator should have a high magnetic flux. The generator would have a magnetic flux of 0.000554 Wb and the total number of coils should be 18.
