A method for erecting a facility includes the steps of constructing initial tower panels on a foundation. Work platforms and guys are installed so that additional tower panels may be installed on top of the existing tower panels. The work platforms with guys may then be raised, so that the process may be repeated until tower section height is reached. Tower sections are them completed by the addition of peripheral trusses and permanent guys, and additional tower sections are constructed by repeating the process to reach the desired facility height. Lifting units including truss and rail systems and rotatable modules with turbines in shrouds are assembled on the ground, then raised up the towers and operably mounted for generating electricity from wind. The erection process is sequenced to maintain structural integrity.
