The Arizona Corporation Commission voted to repeal its Electric Energy Efficiency Standards on Wednesday, finalizing a process that began in 2025.
Regulators adopted the efficiency rules in 2010. The rules directed utilities like Arizona Public Service and Tucson Electric Power to reduce their cumulative energy use by 22% by 2020.
To do so, utilities were incentivized to help their customers purchase energy-efficient appliances and to create programs that conserve energy and lower bills.
Regulators began the process to repeal the standard last fall. Their reasons for doing so were because APS and TEP surpassed the goal in 2024 and it was costing ratepayers money for the utilities to continue filing annual efficiency reports.
