University of Utah Data Center

Project Description

Wasatch Electric applied its considerable complex systems and technology expertise to provide complete electrical and fire alarm installation services for the University of Utah Data Center.

The facility features two large and eight small data halls; a conference room with office spaces; staging, storage, and mechanical areas; electrical rooms; a yard pumphouse; and separate uninterruptable power supply (UPS) and UPS battery rooms.

Scope of Work

Wasatch Electric worked with the project’s design team to help ensure that the highest quality materials were installed as per the owner’s requirements. We also collaborated with the engineers to meet Tier 3 design criteria, including specifications for concurrently maintainable site infrastructure guaranteeing 99.982-percent availability.

The electrical system consisted of three incoming utility power feeds that can be expanded with two additional feeds. Wasatch Electric also installed:

  • Three 3,200-ampere lines of industrial switchgear
  • Five one-MW paralleling generators
  • One 2,000-kW permanently mounted resistive load bank
  • Three automatic transfer switches (ATS)
  • Eight 625-kilovolt-ampere (kVA) uninterruptible power supply (UPS) modules
  • 30 battery cabinets with a total of 40 batteries in each
  • Three UPS tie cabinets
  • Nine switchboards of varying sizes
  • Six automatic static transfer switches (ASTS)
  • Six 625-kV-ampere power distribution units (PDU)
  • Two 225-kVA PDUs
  • Over 2,000 feet of 208-volt busway
  • Multiple variable frequency drives
  • Lighting and controls 

Unique Attributes

Built inside an old bottling plant off-campus, the original building shell required significant structural and seismic renovation, including a seismically designed support system built to keep the data center running during and after a seismic event. 

The system includes an electrical mezzanine hung solely from ceiling joists with no floor supports, which houses more than 25,000 pounds of electrical equipment. Additionally, the data halls use overhead electrical feeds designed to support all of the 208-volt busway and lighting.
