A potential assessment of wind energy at Gharyan, Nalut, Asabah, Alraiyna cities in the western region of Libya is realized for 850 KW Siva wind turbine model. A background information about wind power and its resources was provided, including a review of available data, which are obtained from the representative meteorological stations For the chosen location, a measured long term time series of 3 hours wind data was used, and the wind data has been recalculated to represent the actual wind speed at hub height, The mean wind speed, Weibull distribution, power density function, annual energy and annual capacity factor by creating a data base using Microsoft excel program. Alraiyna has a good wind energy potential were the wind turbine (Siva 850 KW) had an annual energy output equal to 1.275861 MWh. According to the studied machine, the capacity factor was 17.14 %, and the wind resource appears to be suitable for power production.
