On November 17, 2025, the Arizona Corporation Commission (ACC) voted to approve a rate increase for several of the state's major electricity providers. The decision comes after months of deliberation and discussion between the ACC, utility companies, and consumer advocacy groups.The rate increase, which is set to take effect on January 1, 2026, will see a 3% increase in electricity rates for customers of Arizona Public Service (APS) and Salt River Project (SRP), two of the largest utility companies in the state. The decision was made in an effort to help offset rising costs for maintaining and upgrading the state's aging infrastructure and to ensure a reliable energy supply for consumers.The ACC also approved a new rate structure for residential solar customers, which will now be subject to a demand charge based on their peak electricity usage. This change is aimed at encouraging more efficient energy use among solar customers and ensuring that the costs of maintaining the grid are shared equitably among all ratepayers.Consumer advocacy groups have expressed concerns about the rate increase, citing the financial burden it will place on low-income and fixed-income households. However, utility companies argue that the rate increase is necessary to modernize the grid and ensure a reliable energy supply for all customers.In addition to the rate increase, the ACC also announced plans to review and potentially update regulations surrounding distributed energy resources, such as rooftop solar panels and energy storage systems. The goal of these regulatory changes is to promote the growth of renewable energy sources and increase grid resiliency in the face of climate change and other environmental challenges.Overall, the decision to approve the rate increase and review regulations surrounding distributed energy resources reflects the ACC's commitment to balancing the needs of utility companies, consumers, and the environment in order to ensure a reliable and sustainable energy future for Arizona.
