Cost of Wind Transmission Access
The data is presented at both the national and regional level. The national and regional results from each scenario are selectable using the
drop-down box in the database and clicking on the map.
In these supply curves, the cost is only the levelized cost of building the transmission segment from the wind site to the grid (i.e. the cost of generation has been subtracted
from the total levelized cost used in the optimization). By using this approach, users can add in their own costs of generation from wind.
Note also that the costs to build to the grid are specified by wind class. This captures the fact that higher quality Class 5 and Class 6 wind
resources are often more remote than lower-quality Class 3 and Class 4 resources. Finally, note that the cumulative capacity is listed for each
wind class, not the total wind resource in the region.
