The Sierra Club and Synapse Energy Economics released an analysis examining Arizona Public Service’s substantial investment in natural gas infrastructure and its financial implications for utility customers. The report, titled Passing the Buck: How APS’s Gas Rush Risks Ratepayer Dollars, evaluates how the utility’s shift toward gas resources will affect residential bills and explores potential policy mechanisms to mitigate costs.
APS has requested a 14% rate increase that would raise the average residential customer’s annual bill by approximately $240. The utility company is also proposing formula rates, a pricing structure that would permit annual price adjustments with reduced regulatory oversight and public participation. These developments occur as APS scales back its renewable energy commitments and delays the retirement of the Four Corners coal plant previously scheduled for 2031.
The analysis indicates that APS holds the largest portfolio of planned gas projects among Arizona utilities, including the Desert Sun Power Plant and the Redhawk Expansion Project, which involves eight new methane-fired generating turbines in Maricopa County. Environmental advocates note that Maricopa County consistently ranks among the state’s areas with the poorest air quality.
The report’s authors contend that APS lacks sufficient financial incentive to manage fuel cost risks, resulting in the utility transferring all fuel and purchased-power expenses directly to customers. A fuel cost-sharing mechanism, they argue, could encourage the utility to reduce dependence on volatile fossil fuel markets and accelerate the transition toward renewable energy sources. Proponents maintain that expanding gas infrastructure locks ratepayers into higher costs for an extended period while worsening environmental and public health outcomes.
