The utility divide in the data center–led power infrastructure buildout

Vertically integrated utilities are better positioned than transmission-and-distribution utilities to convert data-center-driven power demand into rate-base and earnings growth.

• After roughly two decades of flat U.S. electricity consumption, demand is expected to grow by more than 3% annually through 2030, driven by AI data centers, manufacturing reshoring and electrification.
• About two-thirds of U.S. states retain vertically integrated utilities, while the remainder mainly use deregulated generation alongside regulated wires companies; one large southeastern utility expects about 80% of its incremental demand over the next decade to come from data centers.
• Generation is more capital-intensive than wires: in an illustrative example, serving a data center requires $1,000 of wires investment and $3,000 of generation investment, producing $50 of incremental net income for a T&D utility versus $200 for an integrated utility under identical regulatory assumptions.
• Integrated markets offer data-center developers speed to power, supply certainty and a single accountable counterparty, while large-load tariffs with minimum-take provisions, long-term contracts and credit support can protect residential customers from related costs.
• Restructured markets face affordability pressure: PJM capacity prices rose from under $30/MW-day for 2024/2025 to roughly the administratively capped $330/MW-day in recent auctions, while T&D utilities generally pass those costs through without earning a return on them.

Takeaway: Integrated utilities in high-growth jurisdictions may capture more of the AI infrastructure cycle, but investors still need selective security analysis because T&D utilities retain lower-risk, predictable earnings and expanding transmission opportunities.
