Wind Techno-economic Exclusion

<p><span style='font-size:11.0pt; font-family:&quot;Arial&quot;,sans-serif;'>The
site suitability criteria included in the techno-economic land use screens are
listed below. As this list is an update to previous cycles, tribal lands, prime
farmland, and flood zones are not included as they are not technically
infeasible for development. The techno-economic site suitability exclusion
thresholds are presented in table 1. Distances indicate the minimum distance
