Backup generators, water withdrawal and stormwater are permitted by the state, usually earlier and in more detail than anything filed locally.

- TCEQ Central RegistrySearchable public filings — search the operator, the shell LLC on the deed, and the address.
County & town filings
The rezoning application, site plan, traffic and noise studies, staff report and every revision.
- Search Fairfield (Freestone County) planning filingssearchPlanning departments post application files under many different names. Find the department, then ask the clerk for the application number — that number unlocks everything else.
- Search Fairfield (Freestone County) property records / GISsearchThe parcel record names the buying LLC and the sale date, which is what ties an anonymous filing to an operator.
Utility & grid records
The electricity request is filed with the grid operator and the utility long before the town hears about it — and states the real load.
- ERCOT (Texas) — interconnection queueRequested megawatts, queue position and target in-service date. The MW here is the real number; the one at the town meeting is often phase one.
- Public Utility Commission of Texas — docket searchSpecial contracts, large-load tariffs and rate cases are docketed here. Testimony and exhibits are public, and are usually more candid than the press release.
- FERC eLibraryFederal filings: transmission agreements, interconnection service agreements, and co-location disputes.
- Search the serving utility for a will-serve lettersearchThe will-serve or load-service letter is the utility's own written commitment. Ask the utility and the PUC for it by name — it is frequently the first document to exist.

As of August 2026 (2m ago) · changes weekly — re-check before citing
A working set of identified proposals a community can track, not a census — most of the country's activity is not in here yet. Pennsylvania is the exception: its rows are synced from PA DEP's own data-center permit tracker, so the state's coverage is close to complete and carries the permit trail with it. **Each row carries its own provenance.** Rows showing a verification date link to reporting or the governing body's own record and were read on that date; rows marked *unverified* have no source on record — a lead to check, not a fact to cite. **Stage is derived, not asserted.** *Hearing scheduled*, *Awaiting decision*, *Approved* and *Withdrawn* are computed from each row's milestone dates on every rebuild, so a hearing date that has passed stops reading 'scheduled'. Hearings get moved and projects re-file under new names — treat a scheduled date as the earliest to act by, and confirm with the clerk before relying on it. Leads are mined into data/project_candidates.json and promoted here only after a human reads a primary source.
