1155 Powers Ferry Place data center (Prime Storage site) Approved

Marietta City Council voted 5-2 on Aug 12, 2026 to approve rezoning for an 18 MW, 90,000 sq ft data center at Prime Storage's ~11-acre Powers Ferry Place property near I-75 and Delk Road — the city's second data center. Conditions include silencers on coolers/generators, an independent sound study, no connection to municipal water, and Prime Storage agreeing not to build data centers at its other Marietta sites. The application predated the six-month moratorium the council passed July 8.

State environmental permits

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

The rezoning application, site plan, traffic and noise studies, staff report and every revision.

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.

  • No organised market covers this statenoteThere is no public queue to read. The record is the utility's integrated resource plan and its filings at the PUC — plus FERC eLibrary for anything federally docketed.
  • Georgia Public Service Commission — 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.

Federal databases

Works anywhere, and covers the operator's record at its other sites.

  • EPA ECHO facility searchEvery federally-reported air, water and waste permit at a facility, plus its inspection and violation history. Search by address or draw a radius around the site. This project's locality centres on 33.950, -84.550 — search that point with a 5-mile radius.
  • EPA EnvirofactsThe same underlying records, queryable by county — useful for 'what else is permitted near this site' rather than one facility.
  • EPA Facility Registry ServiceResolves the shell LLC on a permit to the facility it belongs to. Worth a look when the filing name means nothing locally.

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.
