  3. Abstract:
  4. The estimation of the wind resource at the hub height of a wind turbine is one of the primary goals of site assessment. Since in a majority of cities the wind speed is measured at lower heights, the power law model is applied to estimate the wind speed at higher heights. In this study, the wind data for 10 cities in Iran have been analyzed over a period of one year. The accuracy of the power law model to estimate the wind speed has been examined with variations of height and time during this year. The energy production of a wind turbine using the measured wind speeds and the speeds estimated by the power law model were compared. The measured data revealed that in some cities the wind speed rises with height 80% of the time, while it decreased with height in other cities. Results of the study showed that the power law model can estimate the wind speed in some cities with an acceptable error while it shows a high level of error in other cities
