Electric Utilities and Pinnacle West in a Popping AI Bubble

The artificial intelligence (AI) revolution is not just a tech story-it's an energy story. As AI models grow in complexity and data centers proliferate, the demand for electricity is surging at an unprecedented rate. According to a report by the International Energy Agency (IEA), AI-driven data centers are already consuming 4% of U.S. electricity, a figure projected to balloon to 12% by 2030 according to a report by the IEA. This "popping AI bubble" is reshaping the energy landscape, creating both challenges and opportunities for electric utilities. Among the players navigating this high-stakes environment, Pinnacle West Capital Corporation (PNW) stands out as a strategic leader, leveraging its infrastructure investments, partnerships, and forward-looking energy mix to position itself at the forefront of this transformation.

The AI-Driven Energy Tsunami

The energy demands of AI are staggering. A single AI-focused data center can consume as much electricity as 100,000 households according to IEA estimates, and the largest facilities under construction will require 20 times that amount. By 2035, Deloitte estimates U.S. data center power demand could grow thirtyfold, reaching 123 gigawatts according to Deloitte projections. This surge is already straining regional grids, with Virginia's data centers consuming 26% of the state's electricity according to Pew Research. For utilities, the challenge is twofold: meeting surging demand while managing the risks of overbuilding infrastructure and supply chain bottlenecks.

Pinnacle West's Strategic Playbook

Pinnacle West, through its subsidiary Arizona Public Service (APS), is proactively addressing these challenges with a multi-pronged strategy. At the core of its plan is the Desert Sun Power Plant, a 2,000-megawatt natural gas facility near Gila Bend, Arizona. This two-phase project is designed to meet Arizona's growing energy needs, with Phase 1 supporting existing customers and Phase 2 funded directly by high-load users through a "growth pays for growth" model. This innovative approach ensures that costs are not shifted to residential or small business customers, a critical differentiator in an era of rising prices.

Grid Modernization and Resilience

Beyond generation, Pinnacle West is investing heavily in grid modernization. A $45 million allocation in 2024 includes AI-powered fire-sensing cameras to enhance safety and operational efficiency. The company is also expanding transmission capacity, with over $2.5 billion in annual investments through 2028 according to financial reports. These upgrades are critical to integrating renewable energy and managing the volatility of AI-driven demand, which can spike unpredictably during peak training cycles for large AI models.

Partnerships and Market Positioning

Pinnacle West's strategic partnerships further solidify its position. The company has secured additional natural gas pipeline capacity via the Transwestern Pipeline's Desert Southwest expansion project, ensuring grid reliability during peak demand periods. Its CEO, Ted Geisler, has also participated in industry discussions on balancing AI-driven energy needs with sustainability goals according to company updates. These efforts highlight Pinnacle West's proactive engagement with the challenges of the AI era.

Financial Strength and Earnings Potential

Pinnacle West's capital expenditures ($9.66 billion from 2024 to 2027 according to financial analysis) are backed by a robust financial strategy. The company raised its 2025 earnings per share (EPS) guidance to $4.90–$5.10, reflecting strong sales growth and improved transmission revenue. With a long-term EPS growth target of 5–7% according to industry forecasts, Pinnacle West is poised to deliver both reliability and returns in a sector facing existential shifts.

Conclusion: A Utility Built for the AI Age

As the AI bubble continues to inflate, electric utilities must adapt or risk being left behind. Pinnacle West's combination of infrastructure innovation, renewable integration, and customer-centric financing models positions it as a leader in this new energy paradigm. For investors, the company represents a compelling opportunity to capitalize on the intersection of AI growth and energy infrastructure-without the volatility of tech stocks. In a world where every AI query demands more power, Pinnacle West is building the grid to keep the lights on.
