AI data centers are putting pressure on the US electrical grid in ways that did not seem possible just a few years ago, and that strain is a direct benefit to heavy equipment manufacturers, not just chipmakers.
US data center power consumption is expected to increase by 22% in a single year, with total grid demand nearly tripling to 134.4 GW by 2030 as hyperscale buildouts gain speed
Considering grid capacity cannot be increased quickly enough to meet that curve, on-site and backup power production has become a significant portion of AI infrastructure spending, with Caterpillar Inc. (NYSE:CAT) alone accounting for an estimated 18% of the data center generator market. Notably, the company has come to be one of the Dow’s best-performing stocks so far in 2026, with a year-to-date return of 47.81%. Record Backlog and P&E Pivot The company’s Q1 2026 revenue came in at $17.4 billion, up 22% year-over-year, with adjusted EPS of $5.54, above expectations.
The backlog behind that expansion seems to be the real story, with Caterpillar Inc. (NYSE:CAT) closing the quarter with a record $63 billion in order backlog, an increase of 79% year-over-year and $11.5 billion sequentially, owing to major project wins like Altus and Chevron, growing rental demand, and strong Mining segment order conversion. CEO Joe Creed told analysts that the company’s massive engine backlog, which directly powers AI data centers, has grown by over 3.5x since Caterpillar first revealed capacity expansion plans back in January 2024. This backlog progress led Oppenheimer to lift Caterpillar’s price target to $1,105 from $980 on July 13, while keeping an Outperform rating, expecting high-margin Power & Energy deliveries to accelerate in the second half of the year.
