What it would mean nearby

The cooling design has not been reported. If it uses evaporative cooling, a 108 MW facility would draw roughly 342,000 to 1.2 million gallons of water a day, about what 3,900 households use.

Arizona Public Service is asking the commission for a 16.4% residential increase (2025 general rate case (docket E-01345A-25-0105)). On a $160 monthly bill that is about $22 to $30 a month.
