Phoenix, Ariz. — The Hearing in the Arizona Public Service Company (APS) rate case began on May 18, 2026 and concluded on July 7, 2026. The Hearing lasted a total of 31 days – one of the longest utility rate case hearings in the ACC’s recent history; the majority of rate case hearings take about two weeks or less. Nearly three dozen intervenors participated in the Hearing, more than 50 witnesses testified, more than 300 exhibits were admitted into evidence, and about 3,400 data requests were submitted by Staff and other Intervenors to the utility from June 2025 through June 2026. Key topics argued during the Hearing include changes to APS’s Extra High Load Factor (which applies to large load users, such as manufacturing companies and data centers); and the authorization for implementation of a Formula Rate Adjustment Mechanism (FRAM).
The Administrative Law Judge will consider and weigh the evidence presented in this case and the arguments to be provided by parties in their briefs, is expected to provide his Recommended Opinion and Order (ROO) by late November 2026. The deadline for the Commission to vote on the ROO during an Open Meeting is December 31, 2026. If approved by the Commission, the new rates are expected to go into effect sometime in early 2027.
