The Arizona Corporation Commission (ACC), the state's utility regulator, unanimously approved the bill credit in October 2026. The relief is a one-time adjustment, not a permanent reduction in electricity rates. The average residential customer could save approximately $14.70 on their November bill, according to ACC. APS estimates savings of about $14 for a typical household consuming around 1,050 kilowatt-hours (kWh) of electricity per month.
