drivers that are in very short supply. With the pending drop in market activity within the U.S., due to expiration of the PTC, few trailer manufacturers are willing to invest in new equipment with prospects of much lower volumes.

Figure 2-11 U.S. blade logistics capacity Multiple solutions exist to avoid the logistics constraints imposed by longer blades. Segmented blades that ship in separate pieces present a solution to the logistics constraint but add weight and cost to the blade and require expensive on-site assembly that is prone to quality concerns. Segmented blades have primarily been deployed in Europe so far and in limited quantities, but Wood Mackenzie expects significant growth in the deployment of segmented blades in the coming years, as shown in Figure 2-12. Other solutions to longer blades that have not yet been deployed include aerial transportation, mobile factories, and alternative approaches to segmented blades.
