Solar Techno-economic Exclusion

<div style='text-align:Left;'><div><p><span style='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.
