The article highlights that... > Among the surprising findings was that contrary to expectations building subsequent plants based on an existing design actually costs more, not less, than building the initial plant. Given your example wouldn't that mean replacing the wiring of all previous plants of the same design? I suppose this is one way cost overruns get compounded - an issue discovered during the current build would likely apply to the previous builds. (any actual examples of this?)
