Arizona regulators repeal decade-old energy efficiency standards after goals met
The Arizona Corporation Commission voted to repeal its Electric Energy Efficiency Standards, which had been in place since 2010. The standards required utilities like Arizona Public Service and Tucson Electric Power to reduce cumulative energy use by 22% by 2020 through customer incentives for efficient appliances and conservation programs. The repeal process began in fall 2025 after regulators determined the goal had been surpassed and the annual reporting requirements were costing ratepayers.
