The use of wind energy is steadily increasing in the world. An economic analysis for the investment of utilizing wind power plant is needed before installing wind turbines. In this paper, a cost-benefit analysis of the installation of wind turbines was carried out for Ondokuz Mayis University (OMU). Six different scenarios were considered in order to supply energy demand of OMU. It was found that if two turbines were taken into account associated with an average wind speed of 7 m/s, the installation of 750kW wind turbine(s) will result in a positive net present value (NPV) for 20-year life and 30- year life. The internal rate of return (IRR) was also estimated to be 10.35% and 11.75% for 20 and 30 years, respectively. Furthermore, in the case of one turbine with an average wind speed of 6.5 m/s, the IRR for 20 and 30 years were estimated to be 5.89% and 9.56%, respectively
