North Texas Hyperscale Campus

Two substations on the customer side, eight redundant power paths, a connection to the utility’s 230 kV system, and the medium-voltage distribution that delivers power to each data hall. We phased the construction so commissioning and civil work ran in parallel — and the first servers took power on day 423.

Phase 2 1,200 MW (in review)

The challenge we walked into.

A confidential hyperscaler needed 600 MW of power online within 14 months to meet investor commitments on AI training capacity. The host utility had queue position for the connection, but did not have a yard next to the campus site. The developer needed one contractor that could build the substations, the distribution, and the connection to the utility — all on the same schedule.

How we approached the work.

The decisions that kept us on schedule and got the outcome the client needed.

01

One company, all the scope

Civil work through turn-on, all inside our company. Site work, foundations, steel, controls, control building, testing — no subcontractor finger-pointing on the protection scheme.
02

Parallel commissioning

We energized buildings one at a time, so the first servers took load before the last building was finished. The commissioning team worked alongside construction, not after it.
03

Equipment ready early

Transformers and switchgear were ordered through our parent company’s procurement bench and pre-positioned. The long lead times never became our critical path.
04

Coordinating with the utility

Five milestones with the utility, all managed against the campus schedule. First power landed on the day the developer had committed to investors.

What the client got.

First servers took power on day 423. Full 600 MW phase-1 capacity energized on day 426. Phase-2 expansion to 1,200 MW is under review with the same site team.
