UNS Gas filed its first request under a new Annual Rate Adjustment Mechanism, an infrastructure investment tracker the Arizona Corporation Commission approved in February 2026, seeking to recover 41.5 million dollars in system investment. As filed, this would raise a typical residential bill by about 4.4 percent, roughly 2.25 dollars a month on average, though the impact varies by season. New rates would take effect April 1, 2027 if approved.

What it means for your bill: This is a smaller, recurring infrastructure charge, not a full base rate case; it would add about 2.25 dollars a month to a typical UNS Gas bill if approved.
