If the evaluation is only based on general information from weather stations, wind speed at heights above calculation is made taking into account the "roughness of the zone characterized by specific parameters recommended by the literature. Based on experimental data, their values can be verified. Key-words: Wind, wind speed, wind potential, specific energy / power of the wind, graphic variation, roughness parameter 1 Introduction. General Specifications - which will be the cost price (production) of Every project involves risk. In large projects, such electricity when connected to the download as the one seeking to achieve a park of wind network? generators, the risk should be minimized. In fact, the - which is the average lifespan of the turbine itself project of a wind turbine park, involves both certain and related facilities, thereby being able to factors and elements that are characterized as safe, estimate the rate for the investments recovery but also factors which by definition are and its economic profit? unpredictable and can lead to positive results, but The safety of the response to the first question is also failures.
