Abstract: A hybrid wind turbine tower (12) includes at least one polygonal tower section (24) with a polygonal cross-sectional profile connected to a foundation (28), at least one tubular tower section (26) with a circular cross-sectional profile for connection to the nacelle (14), and a transition piece (40) disposed between the at least one polygonal tower section (24) and the at least one tubular tower section (26). The transition piece (40) includes an upper portion having a circular cross-sectional profile connected to a lower end of the at least one tubular tower section (26), and a lower portion having a polygonal cross-sectional profile connected to an upper end of the at least one polygonal tower section (24). A method for assembling a hybrid wind turbine tower (12) is also disclosed.
