7 BLADE MANUFACTURING AND TRANSPORT COST TARGETS 7.1 Off-site manufactured blade costs Based on current blade manufacturing methods, off-site manufacturing costs estimated at $10.45/kg and the scaled blade masses presented in Section 6, the costs of finished blades at the off-site factory are calculated and presented in Figure 7-1. Based on trends to date, LCOE reductions are being achieved with the blade mass scaling rate of R2.2. The off-site manufactured blade costs also provide the target for which production costs from on-site manufacturing and other alternatives shall compete to contribute to overall turbine LCOE reductions, though transportation costs must be added to reflect a more-complete cost comparison.

7.2 Total cost of delivered blade targets Isolating on the Baseline 65 m blade, transportation and handling costs were estimated by industry partners for blades manufactured in Kansas and delivered by truck and rail to the hypothetical project locations in Eastern Montana and Central Michigan. At the time of this work, industry partners reported that they were actively preparing estimates for delivery of blades with very similar characteristics as our Baseline blade to projects under development and construction in the general areas of our hypothetical projects.
