Project overview
A developer secures a 60-acre parcel in a metropolitan fringe market and takes it to a hyperscale tenant as a phased AI compute campus. Land, zoning, water, and fiber all clear early. The binding condition is the distribution substation two miles away, which has committed capacity to other queued projects and a planned upgrade several years out. The project is restructured around that single fact: phased load, on-site generation and storage for the first phase, and full utility service timed to the upgrade.
- Asset type
- Phased AI compute campus
- Design load
- 120 MW at full build
- First phase
- 24 MW, energized ahead of utility upgrade
- Site
- 60 acres, metropolitan fringe
- Nature
- Illustrative composite
Business and infrastructure challenge
The asset could be built years before it could be powered
Construction of the first two data halls could complete in roughly 18 months. Full utility service depended on an upstream substation upgrade with a multi-year schedule controlled by neither the owner nor the developer. Without a change in structure, the campus would sit finished and unenergized while the tenant's compute commitments moved elsewhere.
- Tenant commitments dated against energization, with penalties for slip
- Queue position behind other large loads in the same feeder area
- Long-lead transformer and switchgear procurement
- Carrying cost on land and construction debt during any energization gap

Energy and infrastructure requirements
Stated as obligations, not preferences
- Full-build capacity
- 120 MW
- Reached across four phases rather than a single service request.
- Phase-one capacity
- 24 MW
- Sized to what on-site resources and existing service could carry.
- Redundancy
- Concurrently maintainable
- Any distribution element can be serviced without dropping compute load.
- Storage
- Multi-hour battery system
- Bridges transitions, shaves peaks, and supports ride-through.
- Interconnection
- Transmission-adjacent long term
- Distribution service for phase one; higher-voltage service at full build.
- Water
- Closed-loop cooling
- Chosen partly to reduce permitting and community exposure.
Delivery model
Phased design-build with an owner's engineer and a separate energy infrastructure scope
The buildings were delivered under a conventional design-build agreement. The energy scope — on-site generation, storage, medium-voltage distribution, and controls — was contracted separately so it could start earlier and follow the utility schedule rather than the building schedule. An owner's engineer held the interface between the two, and commissioning was written as a joint acceptance test rather than two independent handovers.
- Step 01
Feasibility
Load study, utility capacity screening, and energization-date scenarios before land closing.
- Step 02
Structuring
Phasing plan, tenant milestones, and capital draws aligned to energization rather than substantial completion.
- Step 03
Early works
Long-lead equipment orders and on-site electrical infrastructure ahead of vertical construction.
- Step 04
Phase-one delivery
First data halls, on-site generation and storage, controls integration, joint commissioning.
- Step 05
Utility transition
Cutover to full utility service as the substation upgrade completes; on-site assets shift to a supporting role.
- Step 06
Operations
Ongoing dispatch, demand management, and performance reporting against the original criteria.
Technology and systems architecture
Layer by layer, and how they interact
- 01
Service and distribution
Medium-voltage campus loop with sectionalizing, designed at full-build capacity so later phases add equipment rather than rebuild the backbone.
- 02
On-site generation
Dedicated generation sized to phase-one load, permitted for continuous duty in early phases and reduced-hours operation after utility service arrives.
- 03
Battery energy storage
Multi-hour system supporting transitions, peak management, and ride-through between source changes.
- 04
Controls and dispatch
A single control layer sequencing utility, generation, and storage, with defined priorities and failure modes rather than device-level automation.
- 05
Compute environment
High-density halls with liquid-ready provisioning; load profile shared with the energy layer so dispatch reflects real behavior.
- 06
Monitoring and reporting
Metering at each interface, producing the evidence base for lender reporting, tenant SLAs, and utility coordination.
Capital structure
Where it comes from, and what each source does
Disclosure
Illustrative structure. No figures are attributed to any real project, and no capital terms are represented as market rates.
Infrastructure equity
Land, development cost, and first-loss position.
Construction debt
Drawn against phase milestones tied to energization.
Term financing
Refinances construction debt once the anchor lease is operating.
Equipment financing
Applied to generation and storage assets with their own useful-life profile.
Public participation
Where applicable, local infrastructure or workforce programs — disclosed in public filings.
Community considerations
What the surrounding area experiences
Load added without shifting cost to ratepayers
On-site resources carry early load, so the campus does not rely on capacity that other customers are waiting for. Cost allocation for the upstream upgrade is defined in public utility filings rather than negotiated privately.
Local emissions and noise
On-site generation is sited, enclosed, and permitted with continuous-duty limits, and reduced after utility service arrives. Both are conditions of the air and land-use permits, not voluntary commitments.
Water
Closed-loop cooling reduces consumptive use, which is often the single most visible community concern for a campus of this scale.
Employment and tax base
Construction employment is substantial and temporary; operating employment is smaller and long-term. Both should be stated plainly rather than combined into one headline number.
Grid services
Storage and flexible load can be made available to the utility during system peaks, converting a large load into a partially dispatchable resource.
Risks and constraints
What can go wrong, and who holds it
- Utility upgrade slips beyond its published schedule
- ResponsePhase-one design does not depend on the upgrade; later phases are contractually gated on confirmed capacity.
- Long-lead equipment delays
- ResponseTransformers and switchgear ordered during structuring, before design is fully complete, with specification tolerances.
- Air permit conditions restrict generation hours
- ResponsePermit limits set the phase-one load ceiling; storage absorbs the variance rather than additional generation.
- Tenant load profile differs from the design assumption
- ResponseControls tuned during a monitored ramp period; storage duty cycle re-specified before later phases commit.
- Interface gaps between building and energy scopes
- ResponseOwner's engineer holds interface ownership; joint commissioning is a condition of acceptance for both contracts.
- Community opposition at permitting
- ResponseWater, noise, and emissions positions established before the first hearing, with the evidence public.
Lessons for future projects
What transfers to the next site
- 01
Energization date, not substantial completion, should drive the capital and leasing schedule.
- 02
Contracting the energy scope separately lets it follow the utility timeline instead of the building timeline.
- 03
Designing the distribution backbone at full-build capacity is usually cheaper than rebuilding it at phase three.
- 04
Permit conditions on generation are a load constraint and belong in the load model, not in a compliance appendix.
- 05
Interface ownership between scopes is worth more than any single equipment decision.
GRIDSTROM perspective
Sequence is the design decision
In projects of this shape, the technology choices are rarely what separates a working outcome from a stranded one. The separating factor is whether the schedule was built around the one milestone the owner does not control. GRIDSTROM works these projects backwards from confirmed energization, then determines what on-site architecture is justified by the gap.
GRIDSTROM did not participate in this project. Analysis is independent commentary.
- Model energization as a range with named dependencies, not a single date.
- Size on-site resources to the gap, not to the full build.
- Specify system behavior — transitions, priorities, failure modes — before selecting equipment.
- Keep vendor-neutral selection inside a single accountable architecture.
