Resumo
The generation of electrical energy by using wind power has improved over the last decade, what explains wide enterprising, especially in Brazil, however it is not noticed a substantial investment in the state of Espírito Santo (ES). The main detail of this kind of renewal energy is the fact that the winds, along the terrestrial surface, do not have a constant speed. Consequently, the wind turbine works with unstable speed. It requires the generator among the wind turbine being able to generate electrical energy with stable frequency in a certain level of speed variation, making visible the need of studies to define the analyze and the viability of this enterprising, what motivated the present research, which the goal is to show a technical and simple study around the area of Urussuquara and a simple financial analyze about a local demanding for energy in order to start a discussion about the viability to install an offshore wind farm in the state of Espírito Santo. Besides the technical and financial viability, it is also necessary to consider the contribution of a wind park in the Espírito Santo by increasing and diversifying the energy of the state, decreasing by this way the dependence of thermoelectric plant and other states that generate electrical energy. The study was performed for Urussuquara Island – ES, seeking to supply the demand of energy performed by the city of São Mateus during 2014 which was 170.590MWh. The outcoming result showed that would be necessary seven windmills of 6MW of power to supply such need. A simplified financial analyze based in payback showed that such investment would be recovered within 6 years and 3 months, what compares to a part of lifetime of a wind farm, therefore it is possible to conclude such enterprising would be, indeed, affordable through the technical and financial view as well.
