What medium-voltage equipment does a data center use?
A data center takes medium-voltage utility power into switchgear, steps it down through secondary unit-substation transformers, and feeds the white space on redundant, tightly monitored feeders.
The equipment Hawk sources for that scope: medium-voltage switchgear, unit-substation transformers, cable terminations and splices on the feeder runs, metal-oxide surge arresters, grounding, and the cable racks that carry feeder cable through manholes, vaults, and tunnels.
How do uptime requirements affect data center switchgear?
Uptime targets drive redundant switchgear configurations and feeder topologies so any single component can be maintained — or fail — without dropping the load.
The Uptime Institute Tier Standard frames the requirement: a Tier III facility is concurrently maintainable, with redundant distribution paths so equipment can be serviced without a shutdown, and Tier IV adds fault tolerance — the effects of an equipment failure or distribution-path interruption are stopped short of the IT load.
Switchgear configuration and redundancy are confirmed against the project’s tier and reliability goals.
What standards apply to data center power?
Data center electrical design references the IEEE 3006 series — recommended practices for power-systems reliability in industrial and commercial facilities — alongside the Uptime Institute Tier Standard and ANSI/TIA-942, which defines four Rated levels for facility resiliency. ASHRAE TC 9.9 publishes the thermal guidelines for data-processing environments.
The medium-voltage apparatus itself is governed by its own standards: IEEE C37.20 switchgear constructions, IEEE C57.12.00 transformers, IEEE 48 terminations, IEEE 404 splices, and IEEE C62.11 metal-oxide surge arresters.
How fast is data-center electrical demand growing?
Lawrence Berkeley National Laboratory’s 2024 United States Data Center Energy Usage Report put data-center consumption at about 176 TWh in 2023 — 4.4% of US electricity — and projects 325 to 580 TWh by 2028, or 6.7% to 12% of US electricity.
That load growth is concentrated in new hyperscale and colocation capacity, and it lands on the same medium-voltage equipment supply base as every other sector. Identify long-lead equipment — switchgear and transformers in particular — at design and order as early as the schedule allows.

Medium-voltage equipment for construction and site development.
Construction projects meet the grid at the service point — the line side is utility-owned and built to the National Electrical Safety Code, and the load side is premises wiring under the National Electrical Code. Large commercial, institutional, and industrial builds increasingly take service at medium voltage and own the distribution past that point: campus loops at distribution voltages such as 13.8 kV, stepped down to 480 V at each building. Temporary construction power is governed by NEC Article 590 — permitted for the period of construction and removed at completion, with medium-voltage temporary installations fenced or barriered to qualified personnel — and jobsite electrical installations fall under OSHA 29 CFR 1926 Subpart K.
The medium-voltage scope Hawk MV Supply sources for construction follows the underground site-development pattern utility developer guides describe: pad-mounted switchgear and three-phase pad-mount transformers, 200 A loadbreak and 600 A deadbreak elbow connectors at dead-front equipment, cable terminations and splices on the primary runs, junction and sectionalizing cabinets, grounding, and pole-line hardware where the service extension runs overhead. Lead times are the schedule risk: Wood Mackenzie projected 2025 supply deficits of 30% for power transformers and 10% for distribution transformers, and three-phase pad-mount availability is projected to stay tight through 2026 and 2027 — identify the long-lead equipment at design and order early.
