This monograph has the main objective to do a comparative evaluation based on strategic, logistics and economics criteria of two alternatives of wind turbine towers that dominate the wind Brazilian market: steel tubular towers and pretensioned pre-cast concrete tower. This study analyses the construction of wind turbines towers in the city of Serra do Mel, Rio Grande do Norte, and it has as the focus the world trend of tall towers development. The commercial exploration of wind power is relatively recent on the world. The first wind turbine to initiate a commercial operation was in Denmark, in 1976. Brazil has started the expressive development on the wind market recently, in 2004, with PROINFA. The country has a large wind potential and the state of Rio Grande do Norte has expressive participation on this scenario. About the methodology, it was applied a literature research to a data survey about the tower alternatives and choice of which would be studied at this research, besides highlight the main criteria to be evaluated. The established criteria were divided on strategic criterial and economical criterial. The strategical criterial that will be highlighted are logistics, the supply of raw material and structural performance of the element. The economic points analyzed were the costs during the equipment lifetime, the acquisition cost and the demobilization cost. The economics comparative evaluations were done, regarding the steel towers, using a real price quote of the market, and, for the concrete towers, were done quantitative estimative to the costs estimative could be done. The results were that the concrete towers has advantage in the strategical criterial and costs and it is the best solution for tall towers. However, the demobilization difficulties of those towers can bring environmental and economic losses that can turn the project unfeasible.
