On Thursday, the Arizona Corporation Commission, in a 5-0 vote, directed staff to file a Notice of Proposed Rulemaking with the Secretary of State’s Office to repeal the Renewable Energy Mandates (A.A.C. Title 14, Chapter 2, Article 18).
According to the Commission, the Renewable Energy Standard and Tariff Rules (REST Rules) were adopted by the Commission in 2006, requiring retail electric utilities to obtain a portion of the utility’s annual retail kilowatt-hour (“kWh”) sales from renewable energy resources including distributed renewable energy resources (i.e., rooftop solar). More specifically, the mandates require utilities after 2024 to obtain 15 percent of retail electric sales from renewable energy resources, with 30 percent of the 15 percent coming from distributed renewable energy resources (i.e., rooftop solar).
The Commission will hold three oral proceedings to receive public comment on the repeal of the REST Rules on November 10 in Tucson, November 12 telephonically, and November 13 in Phoenix. Interested persons may file written comments with the Commission’s Docket Control (RE-00000A-24-0026) by November 14, 2025, and may provide oral comments at the proceedings held on November 10, 12, and 13, 2025.
