Where Caterpillar sits in the stack
Caterpillar's placements in this catalog cover 7 parts, from layer 7 (electrical: power distribution (grid to rack)) to layer 9 (building shell, site & construction). One of them is tagged constrained, meaning a sourced shortage rather than a long lead time. Across these parts it overlaps with other companies most often on the lines below.
What these parts are
- Gas turbines (onsite / behind-the-meter) & HRSGsconstrained — Combustion turbines burning natural gas (or dual-fuel), paired with heat-recovery steam generators, used to generate power onsite or behind the meter at a data center campus.
- Floor PDUs, RPPs, static transfer switches, ATS — Floor-mounted power distribution units, remote power panels, and the static and automatic transfer switches that route power between utility, UPS, and generator sources down to the rack level.
- Backup generation: gensets, fuel systems, HVO — Diesel or gas-fired backup generators, their fuel storage and delivery systems, and renewable diesel (HVO) as a lower-emission fuel alternative, providing power when utility and UPS ride-through are not enough.
- Paralleling switchgear & generator controls — Switchgear and control systems that synchronize and combine the output of multiple generators so they can operate as one larger backed-up power source, and manage the transition between utility, UPS, and generator power.
- Reciprocating engines & engine microgrids — Diesel, natural-gas, or dual-fuel reciprocating engines assembled into modular microgrids for onsite or bridge power at a data center site.

- Is Caterpillar publicly traded?
- Yes — Caterpillar is listed on US exchanges (NYSE/Nasdaq) under CAT. Prices shown on this page are a nightly snapshot, not real-time, and nothing here is investment advice.
- Where is Caterpillar based?
- Irving, United States, per the company record in this catalog.
- Who else makes floor PDUs, RPPs, static transfer switches, ATS for AI data centers?
- Schneider Electric, ABB, Cummins, Delta Electronics, Eaton and Generac are also placed on Floor PDUs, RPPs, static transfer switches, ATS in this catalog.
- How well sourced are these placements?
- Every part→company placement carries a confidence tag. For Caterpillar the mix is 8 inferred. "disclosed" means the company or a filing says so; "reported" comes from trade press or a reference-design list; "inferred" is a lead from the taxonomy with no citation yet. Treat reported and inferred as leads, not facts.
