Arizona Public Service filed on June 13, 2025 for a base-rate increase it reports as $579.52 million net, or 13.99% overall, the figure shown here (the gross figure is $662.44 million, or 15.99%, before moving some surcharge revenue into base rates; on that gross basis the hearing notice puts the residential class at 16.44%). It asks for a 10.7% return on equity and a formula rate mechanism for annual adjustments. Hearings began in May 2026; the Arizona Corporation Commission is expected to vote on the recommended order in December 2026, with any increase likely taking effect in early 2027.
