Key numbers
No cost registered
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
Not published
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
Needs a construction cost
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
15 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
