Sources
Every site, date and dollar figure comes from one of these public records. Each record on a site page links to its original filing.

Environmental permit filings (for example, backup generators) linked to a site.
Linking sites to organizations
Data centers are usually registered under LLCs with unrelated names (“Sharka LLC”, “Rowan Cinco LLC”). A site is linked to an organization only when a record names that organization as the site's occupant, operator, owner or tenant:
- Comptroller registry: the organization appears in the owner, occupant or operator fields.
- TDLR tenant: the organization is the named tenant on a construction registration.
- Manual review: a cited source links the entity to the organization.
A big-company name alone is never enough to merge records. When the link can't be established, the site stays “not linked” rather than being guessed. Each link shows the record that supports it.
Documented, estimated, context
Every number is labeled with what kind of statement it is.
- Documented
- Copied or added up directly from a public record, like a registered construction cost or a certification date.
- Uncloak estimate
- Calculated by Uncloak from documented values, using the methods below. Useful for scale, never a measurement.
- Context
- Background that helps interpret a finding, like statewide grid figures. Not a measurement of the organization or site you're viewing.
“Why this might matter” sections are always context. Uncloak doesn't estimate effects on anyone's bills, water, health or reliability, and it doesn't claim that a site causes any local outcome.
Evidence index
Each site gets a checklist score from the public-record signals below. The score measures how much evidence exists that a project is real and advancing. It's uncalibrated, and it isn't a probability that anything will be built.
| Signal | Points |
|---|---|
| At least one TDLR building registration | 20 |
| Two or more TDLR building registrations | 10 |
| Total registered construction value of at least $500M | 15 |
| A tenant is named in a TDLR record | 20 |
| Certified by the Texas Comptroller data-center program | 15 |
| A TCEQ air permit has been filed | 15 |
| A TDLR inspection has been completed | 5 |
The index is points ÷ 100. Levels: Verified at 70% or more, Likely at 40% or more, otherwise Low evidence. A score dated D uses only evidence dated on or before D, so history can be replayed week by week in the advanced dashboard. Scores were last computed Sep 26, 2026.
Estimated power demand
Public records rarely state a data center's power demand. For scale, Uncloak divides a site's total registered construction cost by an industry benchmark for the all-in cost of building one megawatt of data-center capacity, currently $17.6M per MW (Cushman & Wakefield 2026 Data Center Development Cost Guide (US & Canada average, all-in, excl. chips/GPUs)).
The estimate exists only where a construction cost is registered. Actual demand can be much higher or lower, and the estimate isn't a requested, contracted or measured load.
Missing data
When a record doesn't report a value, Uncloak shows Unavailable, never zero. Totals add up only the sites that have a value and say how many that is (for example, “across 3 of 14 sites”). A site with no published location is listed but not mapped, and nearby searches can't measure its distance.
Avoiding double counting
Each site belongs to exactly one registered entity, and each entity to at most one organization, so organization totals never count a site twice. Construction records that clearly share a legal entity or site code with a registry site are merged into it. Plausible but unconfirmed matches are kept as separate sites rather than merged on a guess. TDLR registrations at one site can overlap (for example, a renovation of an already registered building), which is why summed costs and floor areas are labeled as sums of registrations.
Coverage limits
- Texas only. Company headquarters, and facilities outside Texas, aren't in this dataset.
- The TDLR data comes from a keyword search for “data center”. Code-named projects whose filings don't use those words can be missing.
- Not every site has a construction registration with a cost, so dollar and power figures cover only some sites.
- ERCOT's large-load queue covers all industries, not just data centers, and its scope has changed over time (for example, in-service years counted).
- TDLR doesn't publish inspection dates. Inspections are dated when the status was observed.
Spare connection capacity
Spare capacity compares each existing plant's grid connection with its hourly output. The connection size is the plant's nameplate capacity from the EIA-860 generator inventory. Hourly output comes from EPA CAMPD for fossil units and is modeled for solar and wind, which CAMPD doesn't cover.
For every hour of the latest 365 days, the free room is the connection size minus that hour's output. “Free in 80% of hours” is the largest amount that was free in at least 80% of those hours; “free in 95% of hours” is the same at 95%. Uncloak stores a compact percentile summary for each plant-day in Tiger Data and combines 365 of them, so the figures are close approximations (within about 1%) rather than exact sorts of every hour.
A plant passes a screen when:
- Battery: at least 20 MW is free in 80% of hours. The suggested size is that figure rounded down to 10 MW, for a 4-hour battery that waits out the hours when the plant runs.
- Steady load, such as a data center: at least 50 MW is free in 95% of hours. The load must curtail or run on on-site storage in the rest. Missing fiber within 2 miles is flagged, not excluded.
- Solar plus storage: at least 100 acres of adjacent open land and 20 MW free in 80% of hours. Existing solar farms are excluded, since more panels would compete for the same daylight hours.
These are screens, not feasibility studies. Past output doesn't guarantee future room, the plant owner must agree to share, and total output must stay within the connection. FERC's surplus interconnection service (Order 845) applies to FERC-jurisdictional grid operators. Most of ERCOT is not one, so adding a battery or solar at an existing Texas plant goes through ERCOT's own interconnection process, and pairing a large load with existing generation needs PUCT and ERCOT review under Texas SB 6 (2025). Verify the current rules for each deal.
Every metric, explained
- Sites in Texas recordsDocumented
How many distinct data-center sites in our Texas public records are linked to this organization.
Limits: Counts only sites we could find in these records and link to the organization. Projects filed under code names, or whose ownership we could not resolve, are not included.
- Texas countiesDocumented
How many different Texas counties the organization's recorded sites are in.
Limits: Sites without a published location can't be placed in a county, so the true number may be higher.
- Registered entitiesDocumented
Legal entities (often LLCs with unrelated-sounding names) that appear on the public records and that we linked to this organization.
Limits: A link means the organization is named as owner, occupant, operator or tenant on the record. It does not describe the full corporate structure.
