Key numbers
1 TDLR registration
What this means
The builder's estimated construction cost, added up across the site's TDLR registrations.
Limits: An estimate filed before construction, not an audited amount. Many sites have no TDLR registration, so it's shown as unavailable, not zero. Registrations can overlap, for example a renovation of an already registered building.
Unit: US dollars · Registrations filed to date
245,000 square feet
What this means
Floor area published on the site's TDLR registrations, added up.
Limits: Published for only some registrations, and registrations can overlap.
Unit: square feet · Registrations filed to date
From construction cost, not measured
What this means
A rough size estimate. It's the registered construction cost divided by an average all-in cost of building one megawatt of data-center capacity.
Limits: Not a measured or requested load. The real power draw can be much higher or lower. Available only where a construction cost is registered.
Unit: megawatts (MW) · As of Sep 26, 2026
55 of 100 checklist points
What this means
How much public-record evidence supports that the project is real and advancing: registrations, certification, tenant named, permits, inspections.
Limits: A checklist score, not a probability that the site will be built or operate at any size.
Unit: 0–100% (uncalibrated) · Scored Sep 26, 2026
Why this might matter to you
Without a published location we can't say what's nearby. The records still document who is behind the site and what has been filed.
Registration in the Comptroller program means the state lists this site as eligible for a data-center sales-tax exemption. The registry doesn't publish the value of any exemption.
