Arizona Shifts Strategy with Renewable energy policies: Arizona’s impressive 2024 plan
In a significant development for Arizona’s energy landscape, the state’s 2024 strategy is impressively marked not by new mandates, but by the decision to retire old ones that have been overwhelmingly surpassed. The Arizona Corporation Commission (ACC) has initiated the process to repeal the state’s Renewable Energy Standard and Tariff (REST) rules, a policy established in 2006. This move signals a major shift from a subsidized, mandate-driven model to one where renewables compete on their own economic merits.
A Mandate Achieved: Renewable energy policies: Arizona’s impressive 2024 plan
The original REST rules required utilities to source 15% of their energy from renewable sources by 2025. However, Arizona’s leading utility providers have already eclipsed this target years ahead of schedule. As of 2024, Arizona Public Service (APS) generated 19% of its power from renewables, while Tucson Electric Power (TEP) reached an even more substantial 29%. This success led the ACC to unanimously vote in March 2026 to finalize the repeal, arguing that the customer-funded surcharges—totaling over $2.3 billion since 2006—are no longer necessary to stimulate renewable growth.

Regulators contend that renewable energy has become cost-competitive, obviating the need for government mandates. The ACC cited a Pollack report suggesting that future growth will be sustained by strong consumer and corporate demand from major tech companies like Google and Microsoft. Rather than prescriptive targets, the commission is moving toward an “all-of-the-above” energy strategy. This approach will utilize all-source requests for proposals to procure the most reliable and lowest-cost energy for consumers, a framework in which renewables are expected to continue to thrive.
The Path Forward with Renewable energy policies: Arizona’s impressive 2024 plan
The formal process to unwind the REST rules began in August 2025, culminating in the final repeal. The commission’s decision reflects a confidence in the maturity of the renewable energy market. By eliminating the REST framework, regulators aim to lower utility bills for consumers by ending the associated surcharges. This strategic pivot underscores Arizona’s position as a leader where renewable energy integration has been so successful that the foundational policies guiding its growth are now considered redundant, paving the way for a new phase in the state’s clean energy journey.
