Caterpillar's Role in Project Stargate: What It Signals for CAT Investors
Project Stargate in Abilene, Texas is building on-site natural gas generation to run high-density AI workloads. The site uses multiple simple-cycle gas turbines at roughly 35 MW each, split between GE Vernova and Caterpillar's Solar Turbines unit.
The choice of simple-cycle over combined-cycle isn't about efficiency. It's about speed. Combined-cycle systems can take years to source and commission, while simple-cycle units can be deployed much faster-critical for AI data centers racing to bring capacity online.
Why this matters for CAT
CAT's exposure here is through Solar Turbines, part of its Energy & Transportation segment. As AI facilities look for reliable, quickly deployable generation, simple-cycle turbines create a near-term order book opportunity along with high-margin aftermarket service.
On-site generation also reduces interconnect risk and grid delays for data centers. That dynamic can support ongoing demand for modular power solutions where Solar Turbines competes well.
Key takeaways from Project Stargate
- Configuration: Simple-cycle gas turbines (~35 MW per unit) enable faster time-to-power than combined-cycle.
- Vendors: Equipment split between GE Vernova and CAT's Solar Turbines indicates a multi-vendor strategy and broad demand.
- Decision driver: Lead times are the constraint. Speed to energize outweighs peak efficiency for AI buildouts.
- Aftermarket: Long operating lives and high utilization create recurring parts, service, and retrofit revenue potential.
What to watch next
- Backlog and book-to-bill in Energy & Transportation, with color on data center orders.
- Lead times for simple-cycle packages versus combined-cycle and grid interconnect timelines.
- Fuel and policy backdrop: natural gas availability, emissions rules, and incentives that could tilt choices toward gas, nuclear, or renewables-plus-storage.
- Service attach rates and pricing power in Solar Turbines' aftermarket.
- Mix and margins: whether higher E&T volume lifts consolidated margins or introduces project timing volatility.
Investment view
The data center build is creating a practical need: fast, firm power at scale. That favors CAT's Solar Turbines in the near term. If AI capacity additions maintain pace, orders and services could provide a multi-year demand path.
Risks include shifts in the preferred power stack (e.g., combined-cycle as timelines ease, nuclear approvals, or storage economics), policy constraints on gas, and the cyclicality of large capex. For now, watch E&T commentary, backlog trajectory, and service growth to gauge durability.
