Free excel tool for a very basic estimate of the Wind Farm Energy Production based on the wind Weibull Distribution information.
 
Basic tool that can be used at the very early stage of the wind farm development process, to quickly compare different wind turbine types production estimates for your site.
 
You can add the power curve information of more than 10 different turbine types in the tool.
 
And if the prices of the wind turbine types are included, then a quick basic cost comparison can also be performed (assumed 25 year lifetime)
