APS asked for a net $579.52 million (13.99%) increase, with base rates up $662.44 million, plus annual formula-rate adjustments and a 45%+ increase for data centers. It proposed 16.44% more from residential customers; news reports put the typical household impact near $20 a month. The Attorney General's office argued about 3% would suffice. Hearings ended; a decision is expected late 2026.
