collaboration led by Joule Capital Partners, Caterpillar Inc. and Wheeler Machinery Co. is advancing plans for what the developers describe as Utah’s largest data centre campus paired with more than 4 GW of on-site power generation.
The 4,000-acre project in rural Millard County would combine Caterpillar G3520K generator sets with 1.1 GWh of grid-forming battery storage and a combined cooling, heat and power system that employs liquid cooling—an emerging necessity for high-density artificial intelligence workloads.
While no cost estimate has been released, comparable U.S. mega-campuses point to multi-billion-dollar outlays. Microsoft is investing about US$3.3 billion in its Mount Pleasant, Wis., campus, now under construction and expected to open in early 2026. Google’s Council Bluffs, Iowa, data centre has operated since 2009 and has grown through successive expansions totalling more than US$6.8 billion—including a $1-billion build-out now nearing completion.
