Should your local utility prioritize grid reliability over a faster transition to renewable energy?
As of summer 2026, Arizona Public Service data shows that data centers account for 50% of the utility's energy demand growth. With peak demand projected to rise by 40% by 2031, regulators are prioritizing new natural gas infrastructure.
Why it matters
The rapid expansion of data centers is forcing a shift in state energy policy toward long-term natural gas assets. This transition addresses the grid's need for constant, stable power that current renewable capacity cannot yet provide.
Arizona Public Service customers consumed 90% of planned utility capacity during summer 2026. Peak demand is forecasted to increase 40% by 2031, necessitating a shift toward natural gas infrastructure designed for 20- to 60-year operational lifespans.
The players
Arizona Public Service
The largest electric utility in Arizona that is currently managing a significant increase in energy demand driven by data center infrastructure.
Sierra Club
An environmental advocacy organization that tracks regional energy projects and reports that 15 new natural gas projects are planned in Arizona.
The details
Natural gas plants serve as a vital energy source because they provide voltage stability and continuous power delivery, which are essential for maintaining the electrical grid. While natural gas emits roughly half the carbon dioxide of coal, the infrastructure's reliance on gas poses climate risks, as methane traps between 30 and 80 times more heat than carbon dioxide. To recover the high capital costs of these facilities, utilities are building assets intended to operate for several decades.
Timeline
Summer 2026: Arizona Public Service customers utilized 90% of planned utility capacity.
2031: Peak energy demand for the utility is expected to increase by 40%.
The Tech Race
Arizona is following the precedent set by the 2014 designation of natural gas as a bridge fuel to maintain energy stability. The state is currently balancing this strategy with the development of 15 new natural gas projects to accommodate rising industrial loads.
State residents and businesses will likely see continued investment in large-scale energy infrastructure over the next several decades. These projects are necessary to maintain voltage stability as data centers continue to anchor the state's growing electricity demand.
The takeaway
Arizona is committing to a multi-decade build-out of natural gas infrastructure to meet the immediate power needs of regional data centers. Readers should track the 2031 peak demand forecasts to see if renewable energy scaling can eventually offset the projected 40% growth in load.
