Abstract
This study presents an assessment of the electric energy�s cost in a dairy farm with forty heads of cattle when it is supplied by the grid with wind energy sources. In order to consider the optimal system configuration of wind energy or non-wind energy system, the HOMER program (version 2.68 beta) is used. The possibility of selling electric energy�s excess generated by small wind turbines of different sizes (3, 6, 10, 20 and 50 kW) is analyzed in different locations which have different wind speed average rates, with an established energy demand throughout the year. Moreover, sensitivity analysis based on different prices of electric energy sold (0,22; 0,32; 0,42 �/kWh) and electric energy purchased (0,16; 0,24 �/kWh) are compared in the cost of energy (COE), the internal rate of return (IRR) and the payback time on investment, taking as reference values the option of non-selling electric energy
