Our own notes

These remarks are Arizona AI's own. They say how this record is counted or what we could not find, so there is no outside page to link.

Arizona AI shows the 16 MW figure from TECfusions' July 2026 filing, its most recent dated statement. Arizona AI shows the 133,450 sq ft reported at the 2023 sale and has not established why the 2007 county permit gives a larger total.
