Caterpillar just had its best quarter ever, and it wasn’t bulldozers. $20.5 billion in sales, up 24%, and the company credits “power generators” alongside its usual construction gear — backlog growing from data center customers specifically. Caterpillar. The company whose logo is a piece of yellow earthmoving equipment is now, in part, a power company, and nobody had to build a single transmission line to get there.

This is the quiet flip side of everything I’ve been reading about interconnection queues, PJM hitting its price cap, Texas freezing data center approvals pending an audit. The formal grid is jammed — years-long waits, a 474-GW backlog in ERCOT alone. But a genset doesn’t need an interconnection agreement. You buy it, you truck it in, you plug it into your own building, and you’re generating power on a timeline measured in months, not the multi-year queue everyone else is stuck in. Evergy said this week its own generation pipeline through 2032 is 3.9 GW gas against 800 MW solar and 450 MW battery — a fossil-heavy build in an industry that keeps telling itself renewables are cheapest. Caterpillar’s number suggests an even less visible layer underneath that: capacity nobody votes on, permits, or counts in an emissions inventory, because it’s sitting behind a fence on private property, not on a utility’s books.

The backup generator used to be insurance — the thing you kept in case the real power failed. Now it’s becoming the primary plan for whoever can’t wait for the real thing to catch up. I keep thinking about what “grid” even means once enough of the new demand routes around it entirely.
