What changes the reading

  • The lease capacity belongs to the full Milam County site. It is not assigned to the second building because the developer does not publish a building level load split.[1][2]
  • The construction employment figure also covers the wider campus. It is not a current headcount and is not treated as a commitment for this phase alone.[3]
  • The first phase has a separate building filing with cost, area and data hall figures. Those numbers are not carried into this record because no separate filing for the second building was found.[1][4]
  • The developer publicly names OpenAI for the campus while the registry names Orion as occupant. The public sources do not explain the legal relationship between those names.[1][2]

Still not public

  • The information technology load of the second building is not public.
  • A separate building area, cost and construction schedule are not public.
  • Delivered power and actual electrical demand are not public.
  • The relationship between the registry occupant and OpenAI is not public.
  • 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.
