This is a source-attributed discovery row. It can help you find a place and its citations; it is not a DataCenterData finding that the facility is distinct or currently operating.
Reported geography

The provider combines planned 50 MW and operational 77 MW under a DFW3–DFW5 label, while the earlier reviewed operator citation named DFW3 and DFW4. Building and campus measurement boundaries remain unreconciled, so the whole capacity field stays withheld. The upstream row remains attributed below, but this value is not repeated as site capacity.
Reported details

Provider notes
Energy. CyrusOne signed a 40MW wind+solar PPA with Gexa Energy (announced April 2022) explicitly covering its North Texas data centers, naming Allen, Carrollton, and Lewisville as the sites the purchase powers.
These reviews flag conflicting scope, inconsistent source text or support that has not been established. A withheld value may appear in the explanation, but is not displayed as an established field. The upstream row remains attributed under Sources.
- Cooling: Previously held pending provider-field review. The concern has not been resolved by an independent source review for this captured edition; the field remains withheld.
What the source record says
Confirmed 90-acre, 3-building, 50MW campus at Allen, TX (largest DC development in the state per operator page). AI/HPC (likely): Allen campus marketed for AI training, HPC, multi-cloud.
Any MW value is reproduced as source-reported context. Its measurement boundary is not established consistently enough for comparison. Unknown is not zero.
Status history supplied by the source
No status history was supplied in this edition.
Sources and attribution
These sources are listed for the whole row. Unless a figure links to its own source, the provider does not mark which one gave it, so a figure may not appear in every source.

Compute Atlas 1.34.1 with retained prior rows and publication holds. This is a DataCenterData composite, not an unmodified publisher edition. This row uses the captured source from 1.34.1, source as of 2026-10-14T20:40:52.293Z.
That does not mean the row is wrong, and it does not mean no reviewed record exists for the same place. A link is added only when an identifier or source establishes the match.
