Certified facility dossier

HELO1 DC

A Dickens County site that mined bitcoin under Argo. Galaxy bought it and now leases the whole of it to CoreWeave. Its row is the clearest proof on this site that a registry row names who holds a certification now rather than who held it when it was granted.

What changes the reading

  • The effective date on this row is years before Galaxy bought the site and years before CoreWeave leased it. Nothing is wrong with the row. The state rewrites the parties on a certification while keeping its original date, so a row names the present and dates the past. Every page here is written to that rule.[1][2]June 8th, 2021
  • A second Helios certification exists under a later date and names the same occupant. The state spells the first one with a letter where the second uses a digit.[1]

Still not public

  • Square footage and acreage are not public.
  • Cooling design is not public.
  • The split between retrofit and new build is not public.
  • Which physical buildings each of the two certifications covers is not stated.

What was filed to build it

Texas registers every large construction project with a second agency. These filings were made by a company this record already names.

$800,000,000 across 1 filing, 147,457 sq ft.

An estimated cost at filing is not a final cost, and a filing is not proof a building went up. How this register works.

The registry entry for this facility comes from the Texas Comptroller's certified list of data centers holding a sales tax exemption. Owner, occupant and operator are roles in that filing rather than descriptions of who runs the building.
