Fifteen years ago, lattice towers dominated wind-farm landscapes. When hub height hit the 60m mark, developers turned to steel tubular designs that have not changed much – until recently. For this blog, we contacted several tower manufacturers to see what’s new and what might push towers beyond 100m. Why taller Towers that reach over 100m…
First North American concrete wind-tower base reaches 40m
At AWEA’s recent WINDPOWER 2012 tradeshow, a precast concrete manufacturer unveiled its 40-m tall concrete wind-tower base with tours of its Conley, Ga. facility. Guests got a first-hand view from inside and outside the prototype built on company grounds. The base is intended to provide a less expensive structure than an all-steel tower for raising towers…
Atlas shrugged? Not this tower base
A manufacturer of precast components offers a new concrete tower base. Tindall Corp’s Atlas CTB is certified from Germanischer Lloyd, an important step in the company’s development of wind tower technology that will allow the industry to extend hub heights above 100 m to generate more power
