Questions this page answers

Is Stargate Lighthouse Campus under construction?
No permit record shows it yet, so this page prints it as announced. Compute Atlas (Sep 13, 2026) reports it as under construction. The sources disagree: EPA ECHO reports operating.
Who is building Stargate Lighthouse Campus?
Vantage Data Centers is the operator. No public record names the general contractor yet. It shows here the day one does.
Which carriers serve Stargate Lighthouse Campus?
No public record names them yet. They show here when a filing does.
How do contractors on Stargate Lighthouse Campus get paid sooner?
The owner pays the general contractor, and the general contractor pays its subcontractors. Once your customer approves your invoice, certify it with Kapwork. Funders compete to fund it, so you don't wait for the payment date. Free for businesses. Kapwork doesn't lend and doesn't contact your customer.

Already invoice Vantage Data Centers?

Crews on a campus like this invoice the GC and the carriers in their own portals. Certify the unpaid invoices. Kapwork proves they're real so funders fund them sooner while the GC takes its time. Free for businesses.

Limitations and interpretation

  • This record is the Kapwork Grow tracker's merged view of a facility, from the tracker snapshot built 2026-11-02. Facts tagged KW are the tracker's resolved values; the per-source rows it was merged from are listed under Sources and on the tracker record.
  • Sources on this record: Compute Atlas: Kubiak, E. (2026). Compute Atlas [Data set]. https://doi.org/10.5281/zenodo.22284476 (CC BY 4.0) · US EPA Facility Registry Service via ECHO (public domain). Every source is licensed for commercial use with attribution.
  • An announced or permitted build is not a contract, an open bid or a purchase order.
  • Capacity figures are as reported by the cited sources and may describe planned rather than energised capacity.

“Not reported” means missing information, not zero. Completed and withdrawn records can remain available as historical records.

Nearest build: Haversine great-circle distance on the tracker latitude and longitude, in statute miles, rounded to 0.1. First-seen dates: first_seen: the earliest committed snapshot of data/dcfo.sqlite holding any of the facility's source keys (source:source_id), narrowed to the nightly run day by the alert sender's facility_new events when they are available. status_first_seen: the start of the unbroken run of snapshots, ending at this one, in which a facility sharing a source key had the current status, narrowed by the latest status_changed event to that status. Dates are Kapwork's, not the sources'.

What we don't know yet

  • The building area, the general contractor's name and the completion date.
  • The carriers that serve the campus.
  • How the operator and its GC pay their contractors: portal, terms, days to pay.
