Cat for Joule Data Center Campus
Cat announced an agreement with Joule Capital Partners to supply a 4 GW power solution for Joule’s High Performance Compute Data Center Campus, located about 145 miles south of Salt Lake City

Joule Capital Partners, Cat and Wheeler Machinery announced an agreement to power Joule’s High Performance Compute Data Center Campus in Utah. More on Data Centers. In July, we told you about the Shanghai Tencent Cloud Data Center. In May, we even shared what happens upstream of the design and installation of a backup system, at the CAT Demonstration Center in Malaga, Spain.

This initiative will provide four gigawatts of total energy to the center of the Intermountain West. The project will deliver groundbreaking 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.
All inclusive
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.
“This project represents the core of Joule’s mission—to deliver artificial intelligence (AI) ready compute capacity by pairing world-class data center campuses with reliable, on-demand power,” said David Gray, President of Joule Capital Partners. “By combining Caterpillar’s advanced energy systems with Wheeler’s local expertise, we can bring gigawatt-scale capacity to market faster and more efficiently than ever before, ensuring our tenants have the power and reliability they need to thrive in the next generation of high-performance computing.”

“Caterpillar is uniquely positioned to tackle the growing energy needs for artificial intelligence and the evolving needs of modern infrastructure. This project is a perfect example of how we can deliver fast, reliable power generation to our customers through integrated energy solutions,” said Melissa Busen, senior vice president of Electric Power at Caterpillar.
