On August 26, 2025, the Arizona Corporation Commission conducted a workshop focused on the expansion of natural gas infrastructure and storage in the state. The event was organized by Vice Chair Nick Myers, who initiated docket G-00000A-25-0029 earlier this year to address issues related to Arizona’s natural gas system.
The workshop addressed several key topics: the current status of gas infrastructure and storage in Arizona, increasing demand for natural gas from utilities and businesses, updates on ongoing and planned projects, as well as market and regulatory developments affecting infrastructure expansion.
Vice Chair Myers emphasized the importance of these efforts. “Expanding natural gas infrastructure in the state is critical to ensuring Arizona’s energy reliability into the future,” stated Vice Chair Myers. “With upcoming generation retirements, increasing reliance on intermittent resources, and the surge in demand from data centers and industry, it’s clear that firm natural gas capacity is essential. Addressing our current supply constraints is not just a challenge—it’s an opportunity to secure our energy future.”
Presentations during the workshop were delivered by representatives from organizations such as the American Gas Association (AGA), National Energy Dominance Council (NEDC), and Federal Energy Regulatory Commission (FERC). Major Arizona utilities—including Arizona Public Service Company (APS), Salt River Project (SRP), Tucson Electric Power (TEP), UniSource (UNS), Arizona Electric Power Cooperative (AEPCO), and Southwest Gas Corporation (SWG)—highlighted their need for additional infrastructure to ensure grid reliability amid rising customer demand.
Project developers like Transwestern Pipeline, Kinder Morgan, Tallgrass Energy, and Grupo CLISA provided updates on both current projects and those planned for the near future. Stakeholders from inside Arizona as well as neighboring states also contributed insights; these included representatives from groups such as the Arizona Chamber of Commerce & Industry, Western Resource Advocates, and Western States and Tribal Nations Energy Initiative.
The session featured detailed discussions about how best to support growing energy needs while maintaining reliability across systems that are facing new pressures due to increased industrial activity and changes in electricity generation sources.
Vice Chair Myers closed with appreciation for participant contributions. “I’m very pleased with today’s discussion and grateful to everyone who participated. Expanding natural gas infrastructure is essential to securing Arizona’s long-term energy reliability,” concluded Vice Chair Myers. “Today’s workshop reinforced my belief that we are moving in the right direction.”
The full workshop recording along with presentations are available through the Commission’s website for those interested in reviewing proceedings or learning more about ongoing initiatives.
