Power for AI and data center campuses.

AI training campuses use enormous amounts of power — anywhere from 100 megawatts to 1.2 gigawatts. We build the substations and power distribution that feeds each building, and we sequence the work so the first servers can take power before the rest of the campus is even finished. That timeline often matters as much as the equipment itself.

FIG— 06.A  ·  345/138 KV CUSTOMER-SIDE SUBSTATION FOR DATA CENTER CAMPUS

Power for AI and data center campuses.

We build the substations and the redundant power lines that feed each building on a hyperscale campus. Because we phase the turn-on building by building, the first servers can come online months before the rest of the campus is complete — which is often the difference between making and missing investor commitments.
  • A

    Customer-side substations

    A customer-side substation sits on the developer’s land and steps the utility’s high voltage down to what the data halls use. Building it under our own contract is faster than waiting for the utility.

  • B

    Redundant power distribution

    Each data hall gets at least two independent paths for power. If one path has a problem, the other keeps the servers running. We design and build both paths.

  • C

    Phased turn-on

    Instead of waiting for the whole campus to be finished, we energize buildings one at a time. The first servers can take load months before the last building is even built.

  • D

    Coordinating with the utility

    We work with the utility on the technical studies, queue position, and approvals needed to connect the campus to the grid. The developer signs the agreement; we handle the engineering coordination.

How a project runs, step by step.

Every step happens inside one company — civil work, steel, electrical, and the controls that protect the system. All on the same payroll.
  1. 01

    Pre-construction

    Working with the utility on the connection study, coordinating designs, and ordering the long lead-time equipment (especially large transformers and switchgear).

  2. 02

    Site work

    Building the pads where the substation will sit, digging the trenches, and installing the underground duct banks for the medium-voltage cables.

  3. 03

    Substation construction

    Building the customer-side substation while the utility builds its connection on the other side. Both happen in parallel.

  4. 04

    Power distribution

    Pulling the medium-voltage cables to each building and installing the equipment that delivers power to the data halls.

  5. 05

    Phased turn-on

    Energizing buildings one at a time. The first servers take power before the last building is finished — often making the difference on the overall schedule.
