Table 6-3 summarizes the estimated non-recurring costs associated with each deployment of the on-site blade factory, as adjusted with the scaling factors presented above. The costs are further translated into cost per blade, based on the blade counts at the Montana and Michigan project locations.

Recurring costs for blade production correspond to the blade mass multiplied by the adjusted on-site blade production cost of $11.84/kg. Figure 6-4 presents a summary of the blade cost adder combined with the original cost of an off-site manufactured blade.
