Caterpillar, Joule & Wheeler Announce an Agreement to Power Data Center Energy Needs

IRVING, Texas (Aug. 7, 2025) — Caterpillar Inc., Joule Capital Partners and Wheeler Machinery Co. announced an agreement to power Joule’s High Performance Compute Data Center Campus in Utah. Joule, a next-generation infrastructure company, aims to create the largest single campus in Utah and operate the most advanced data centers in the world.

Bringing Multiple Gigawatts of Capacity to Utah 

This initiative will provide four gigawatts of total energy to the center of the Intermountain West. The project will deliver prime power and integrated combined cooling heat and power (CCHP) solutions with a by-design liquid cooling architecture. Powered by a fleet of Caterpillar’s latest G3520K generator sets and support equipment, the distributed generation system produces electricity and captures waste heat to power and cool next-generation, high-density server systems. 

The solution includes 1.1 gigawatt hours of grid forming battery energy storage along with backup power generation served by diverse fuel sources. Thanks to Caterpillar’s expanding U.S.-based manufacturing footprint, the full generation package can be delivered ahead of most other generation technologies. This speed-to-power advantage is critical for meeting the explosive growth in demand for compute capacity. 

Beyond the gensets, this fully integrated system includes the controls, switchgear, inverters, energy storage solutions, CCHP and more, providing a complete power solution for the Joule data center and a competitive advantage for Joule’s tenants. Caterpillar and Wheeler will also provide service and support for the products and solutions, ensuring uptime and availability targets are met.
