Rate case 2019: serving customers with clean, reliable and affordable energy

Unlike most companies that can set prices for their products, APS is a regulated utility that must file a request with the Arizona Corporation Commission (ACC) to open a public process called a rate case. Our 2019 request, submitted at the direction of the ACC, is designed to recover investments we’ve made to our system that is cleaner, better integrated with renewables, and continues to reliably serve the needs of a growing Arizona.

The process

A rate case seeks to balance the needs of customers and the utility. It determines the price customers pay for safe, reliable electricity. It also authorizes the opportunity, but not guarantee, to earn a competitive rate of return to support a financially sound utility, which in turn helps attract more investment into Arizona’s largest energy system. A utility’s request to set new rates undergoes an extensive examination over a period of many months.
