A wind turbine (300, 400, 500), tower (302, 402, 502) and method (600) for making same are provided. The wind turbine includes a rotor (308) having one or more blades (312) and a rotor radius distance (309) approximately equal to the distance measured from a centerline (307) of the rotor to a tip (313) of one of the blades (312). The tower (302, 402, 502) has one or more tower sections, including a first tower section (306, 406, 503) having a generally cylindrical or frusto-conical shape. The first tower section has at least one first diameter. A reduced diameter tower section (320, 420, 520) is connected to the first tower section, and has a waist portion (424, 524) with at least one second diameter that is smaller than the first diameter. At least a portion of the reduced diameter tower section having the second diameter is located about one rotor radius distance from the centerline of the rotor, and the reduced diameter section provides increased static clearance to the tip of the blades. |
