Houston, Harris County, TX
DataBank HOU2 (Westway Park II), formerly CyrusOne Houston West II
Why this stage: The building is an operating data center. CyrusOne's FY2021 10-K lists Houston West II as a stabilized property with 12 MW of critical load, and TCEQ shows an active generator registration now held by DataBank. These records predate Denvr or name no tenant. The only record naming Denvr at the address is a Texas sales tax permit.
- Owner or developer
- DataBank, through owner entity Data Center Houston, LLC, which lists DataBank's Dallas headquarters address. CyrusOne owned the building until the 2022 sale.
- Denvr Dataworks's role
- Tenant at the address, per a Texas sales tax permit. The lease type is not stated in any record.
- Link to Denvr Dataworks

Unverified: not found in online records
- No record states Denvr's megawatts, GPU count or data hall at this building.
- The link between Denvr's HOU1 region and this address rests on a sales tax permit outlet, not a lease or a Denvr statement.
- The 2026 TDLR expansion names no tenant. It is unknown whether any of the 6 MW is for Denvr.
- No utility or grid record for the site was found online.
- Sources disagree on where Denvr's 1,024-GPU H100 cluster sits. Denvr's docs list H100 nodes only in Houston.
