The wind is almost seasoned and efficient of all renewable energies. The wind turbine tower (WTT) with a horizontal axis. It supported on steel, concrete, pre-stressed, hybrid, tower. As the turbine size grows up, the is heightened to generate spadesful of electricity power. The hybrid tower consists of pre-stressed concrete in the bottom and steel at the top. The parts of the steel tower have to be reasonably rigid, this design requirements raise the cost of a construction lifetime and decrease maintenance condition. To solve and improve this problem, a new proposed of the prestressed concrete (PC) structural system for the horizontal axis (WTT). The introducing tower is designed as an octagon section with internal ribs in the bottom along the hight of the tower with reducing in dimensions at different hight. The aerodynamic principle ware considered in optimizing the transverse profile of the tower. 100 m height of the tower system for the 3.6-megawatt turbine was designed using FE software (ANSYS).
