On July 10, 2025, the Arizona Public Utility Regulation Board made a controversial decision to approve a rate increase for Tucson Electric Power (TEP). The decision has sparked debate and concern among residents and consumer advocacy groups statewide.The rate increase, which was requested by TEP earlier this year, is said to be necessary in order to cover the costs of maintaining and upgrading the utility's infrastructure. TEP cited increasing operational expenses and the need to invest in new technologies as reasons for the rate hike.According to TEP officials, the average residential customer can expect to see an increase of approximately 4.5% in their monthly bill. This means that the average residential customer will have to pay an extra $7-$10 per month, depending on their usage.However, consumer advocacy groups argue that the rate increase is unjustified and will impose an unfair burden on low-income residents. They believe that TEP should be able to cover their expenses without passing the costs onto customers.In response to the decision, groups such as the Arizona Consumer Advocacy Coalition have vowed to challenge the rate increase in court. They argue that the Arizona Public Utility Regulation Board failed to adequately consider the impact of the rate hike on consumers and did not provide enough justification for their decision.Despite the controversy, the Arizona Public Utility Regulation Board defended their decision, stating that they carefully reviewed TEP's proposal and concluded that the rate increase was necessary for the utility to continue providing reliable service to customers.As the debate continues, residents are bracing themselves for the impact of the rate increase on their monthly utility bills. It remains to be seen whether consumer advocacy groups will be successful in their efforts to overturn the decision.
