The largest data center in the US is coming to this rural Utah county

FILLMORE, Utah (ABC4) — In early June, Millard County approved a rezone that will bring the world’s largest data center to central Utah.

On June 3, 2025, the Millard County Commission unanimously voted in favor of a rezone, appropriating over 1,100 acres of agricultural land to heavy industrial. The center would be house high-density data banks which can be leased to major tech corporations for a number of uses including artificial intelligence.

The applicant is a management company called Fibernet MercuryDelta, LLC. The company was only created in 2022, but last month reported almost $15.2 million in annual sales.

Rezoning the property paved the way for Fibernet MercuryDelta to construct what they’re calling the largest data center in the U.S. The property in question is found near the intersection of 4500 South and Highway 50 in Delta.

One nearby resident of the potential data center, Kyle Ashby, voiced concerns over water usage. “What’s troubling is the actual amount of water hasn’t been clearly defined or publicly released.”

Jarvis Jones, another nearby resident, feels the project could set a dangerous precedent.

“This zoning could create a domino effect, inviting further industrial development,” Jones said during the June commission meeting.

Millard County commissioners pointed to economic benefits in favor of the data center, including Commissioner Bill Wright who highlighted the “significant benefits a large company could bring to the county.” Wright says benefits could include job creation and increased tax revenue.

The project is not the only one of its kind coming to Millard County. On Aug. 5, 2025, the Millard County Commission approved the rezone that will bring another major data center to the county.

Fibernet MercuryDelta now only needs a conditional use permit before beginning construction.
