Arizona is facing a challenge that more states will soon confront: electricity demand is rising quickly, and the energy system must keep pace.
This summer made that clear. Arizona Public Service (APS) customers broke the utility’s all-time peak demand record twice as extreme heat, population growth, and expanding economic activity pushed electricity use higher.
But Arizona’s experience is about more than record demand. It offers a case study in how states can welcome new investment and economic growth while keeping affordability and reliability at the center.
Arizona Offers a Model for Responsible Growth
New data centers, manufacturers, and other large energy users can bring jobs, investment, and economic opportunity. But growth should not mean families and small businesses are left paying for the infrastructure needed to service these customers or competing for limited grid capacity.
One example of Arizona’s approach is APS’s new Pledge for Responsible Energy Growth, which puts clear guardrails around how extra-large energy users are added to the system.
The framework centers on three principles: safeguarding reliability, protecting customer rates, and preserving capacity for future growth.
At its core, the approach is simple: growth should pay for growth.
APS says it will not connect extra-large customers faster than the grid can reliably support them. New, extra-large energy users should cover the costs associated with serving them, rather than shifting those costs to existing customers. At the same time, capacity is being preserved for the homes, schools, hospitals, and businesses that Arizona will continue adding in the years ahead.
A Blueprint Other States Should Watch
Responsible growth also requires making sure enough energy is available as demand rises. That means continued investment in generation, transmission, and grid infrastructure, supported by a diverse mix of resources that can deliver power when consumers need it most. Natural gas and nuclear remain critical to that equation, working alongside solar, storage, and other technologies to support affordable, reliable, and increasingly cleaner energy.
Arizona should not have to choose between economic opportunity, affordability, and reliability. Neither should other states.
As more states face rising demand from population growth, manufacturing, data centers, and other large energy users, Arizona offers a useful blueprint. Growth can bring jobs and investment without shifting costs onto existing customers or compromising reliability. The key is planning ahead, building the infrastructure needed to keep pace, maintaining a balanced energy mix, and making sure new demand pays its way.
That is responsible energy growth, and it is an approach other states should be watching.
