The Arizona Corporation Commission voted July 8 to eliminate the state's electric energy efficiency standard, a reversal of a policy first adopted in 2011 that advocates say helped keep bills stable and eased strain on the power grid.
Reversal follows earlier renewable rollback
The unanimous vote among the four commissioners present came after the same board in March 2026 moved to undo the state's renewable energy standard, a policy adopted in 2006 that required regulated utilities to generate 15% of their electricity from renewable sources by 2025. Former Chair Kevin Thompson, who led the effort to begin repeals, was absent for the July vote.
Supporters of the rescinded efficiency rule — including elected officials, environmental groups and consumer advocates — warned the combined rollbacks amount to a policy shift that will increase future electricity demand, lift customer bills and encourage new fossil fuel infrastructure that could emit greenhouse gases for decades.
Officials clash over motive and effect
Commission Chair Nick Myers defended the move, saying the standards were outdated and that efficiency gains from modern technology no longer require what he described as ratepayer-funded subsidies. Opponents say that reasoning ignores the role of standards in promoting utility investments that reduce consumption and delay costly generation projects.
"Utilities will now have less reason to invest in efficiency and every reason to build costly new infrastructure they can charge customers for," Arizona Attorney General Kris Mayes said. "Families will pay more, and the grid will be under more strain during peak summer hours."
Mayes, who previously served on the commission and later ran for attorney general, issued an earlier written objection when the commission began the repeal process in September 2025 and formalized her challenge in March.
- 2011: State electric energy efficiency standard adopted.
- March 2026: Commission rescinds 2006 renewable energy standard (15% by 2025).
- July 8, 2026: Commission votes to repeal the 2011 efficiency standard.
What this could mean for Arizonans
Energy efficiency standards traditionally push utilities to offer programs and incentives that lower customer demand and delay investments in new generation or transmission. With the efficiency rule gone, utilities may face fewer regulatory requirements to run such programs, which could translate into higher demand during Arizona's hot summers and put more pressure on rates and reliability.
| Policy | Year Adopted | Current Status |
|---|---|---|
| Renewable energy standard (15% by 2025) | 2006 | Repealed (March 2026) |
| Electric energy efficiency standard | 2011 | Repealed (July 8, 2026) |
The commission, an elected body that regulates utilities across Arizona, has faced criticism from consumer and environmental groups that argue the rollbacks favor utility financial interests over ratepayer protections. Commissioners advocating repeal say technological advances have made the rules unnecessary.
For customers, the practical implications — from monthly bill changes to the timing and scale of new utility projects — will unfold as utilities and the commission adjust to the policy changes. For policymakers and advocates, the votes mark a turning point in how Arizona balances reliability, affordability and climate considerations as demand grows.
Reporting will continue as opponents pursue legal and administrative avenues and utilities signal whether they will alter programs formerly driven by the efficiency standard.
