 Based on the long-term corrected wind data a wind potential map is calculated for the feasibility study using analysis software (e.g. WindPro and WAsP. Considering this map and the outcome of measurement campaign and data analysis the appropriate wind turbine type is selected. Usually several scenarios using different sizes, numbers and types of turbines are considered and their cost and benefits are take into account during the financial viability assessment of the project.

 In a reverse process, the generalised regional wind climate is then applied to topography, surface description and obstacles at the vicinity of each individual wind turbine, providing the wind flow at this point even if the wind data has measured in some distance<br/>which can be, depending on the terrain, up to several kilometres.&nbsp;
 A very important aspect of estimation of energy production for use within a feasibility study is the determination of potential losses and uncertainties caused by uncertainties in variables and parameters of the used model. Meteorological phenomena can only be predicted to a certain limited degree. As a consequence it is not possible to make an exact forecast of the wind conditions even if long-term reference data is used.
