Is it that expensive? In terms of raw materials it may cost more, but not double. The use of prefabricated parts (torso, limbs) reduces each tower's uniqueness and therefore complexity of repairs. Fabrication of unique beams is well within the repair capability of a mobile crew. Is the actual material cost of each tower a major component of a transmission line cost model? I am betting no; transmission wire, ongoing maintenance, land and rights acquisition, and monitoring probably make up the bulk of a transmission line's cost. Finding actual data on this is proving to be difficult, however.
