Wind speed studies have been carried out to find the feasibility and efficient utilization of wind energy as a source of energy in Pakistan.

Hourly wind data for more than 50 locations in Pakistan for a period of 5-10 years have been analyzed for estimation of wind speed, wind power and energy. The wind speed contours (isovent maps) are prepared for each month and on annual basis by taking average over a period of twenty five years which categories the wind potential into low 1-2 m/s. After the analysis of such data for each observatory, we select the ten highly potential areas spread all over the country for our research purpose,. Monthly and vearly wind speeds, wind power and energy are also determined for each station. Different continuous distributions like weibull, Ravleigh, Normal and Chi-square are applied and a comparison is made. Different methods are tested for estimating the weibull parameters such as in moment estimator, maximum likelihood estimation, and velocity moment method and regression analysis.
