What changes the reading

  • The building filing names Freebird and identifies OpenAI in its tenant field. The tax record uses an Orion project company as occupant. The records use different legal labels and do not publish the relationship between those entities.[1][2][3]
  • The OpenAI lease belongs to the full Milam County site. It is not the information technology load of the first building and should not be assigned to that building alone.[2][3]
  • The nearby Orion solar projects supply Google through a separate power agreement. Their shared name with the registry occupant does not prove that the solar output is dedicated to this data center.[1][4]
  • The developer says the wider campus is under construction. The first building's filed end date remains a schedule and is not treated as an operating date.[2][5]

Still not public

  • The information technology load of the first building is not public.
  • Delivered power and actual electrical demand are not public.
  • The relationship between the registry occupant and OpenAI is not public.
  • The source and timing of new generation for the campus are not established.
  • Cooling design and measured water use are not public.

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.
