During a meeting on January 26, 2022, the Arizona Corporation Commission voted 3-2 to reject the adoption of a set of clean energy rules.[1] Included in the rules package was a proposal to require the state’s investor-owned utilities to provide all of their electricity from zero-carbon resources by 2070. In the interim, the package would have required utilities to cut their carbon emissions by 50% by 2032 relative to average emissions between 2016 and 2018. The package also included new demand-side resource standards and integrated resource planning reforms. In addition, the package would have expanded energy efficiency programs for Arizona Public Service (APS) and Tucson Electric Power (TEP). APS and private companies that do business in Arizona like Apple Inc., PayPal Holdings Inc., and Ikea have expressed support for the package.

Although the commission had previously voted in favor of the 100% clean power plan, the three Republican members ultimately voted against the package. Commission Chair Lea Marquez Peterson, R, cited cost concerns. Commissioner Jim O'Connor, R, also said state-level rules were not necessary as utilities have already made commitments to clean energy. Democrat commissioners Anna Tovar and Sandra Kennedy argued that the rules would cut customer bills and spur investments in clean energy.
