The data center fight in Memphis, Tennessee

As of October 1, 2026, Memphis, Tennessee has a data center moratorium under consideration (action taken Aug 18, 2026).

Status is derived, not stored — a pause with a documented end date flips to Expired on its own — and the source is right next to the claim.

12-month pause on data center rezonings, site plan approvals and building permits, advanced out of committee and passed first reading on a voice vote; further readings are required before it takes effect. Sponsored by council chair Jana Swearengen-Washington with J.B. Smiley Jr. and Yolanda Cooper-Sutton. Would NOT reach xAI's existing Colossus facilities — only new approvals. Some residents are pressing for 18-24 months

An expiry date is the earliest a pause could have ended — extensions are common, so confirm with the clerk before citing it.

The projects on the table

xAI Colossus — Approved

Operator: xAI · Tenant: xAI · Size: 2,000 MW

Operating and expanding (~$20B, ~2 GW ambition). The live fight is air quality: on-site gas turbines in southwest Memphis - an area already failing federal ozone standards - drew a Clean Air Act suit. Environmental groups' tracking put unpermitted turbines at 27 in Feb 2026, growing to 59 by mid-2026 across the Colossus complex (incl. Colossus 2 in Southaven, MS).

Next: Approved — pivot from stopping it to a binding CBA: enforceable caps on noise, water and cost, plus a community benefit.

Latest in the record

  • 2026-06-16 — The U.S. Department of Justice moved to intervene in the NAACP's Clean Air Act suit and urged the court to dismiss it, arguing that shutting off xAI's Southaven turbines would harm national, economic and energy security because the Grok AI model supports Department of War military operations, including recent strikes involving Iran. · source
  • 2026-05-06 — The NAACP asked the U.S. District Court for the Northern District of Mississippi for a preliminary injunction to halt xAI's gas turbines at its Southaven facility while the Clean Air Act lawsuit proceeds, as reported May 6, 2026. · source
  • 2026-04-14 — NAACP, represented by Earthjustice and SELC, filed a Clean Air Act suit against xAI and MZX Tech (N.D. Miss.) over unpermitted gas turbines serving the Colossus complex. · source
  • 2026-03-10 — The Mississippi Environmental Quality Permit Board unanimously approved a PSD construction permit allowing xAI affiliate MZX Tech to install 41 permanent methane gas turbines at its Southaven plant powering the Memphis data center operations. · source

  • 2026-02-13 — Earthjustice and the Southern Environmental Law Center, on behalf of the national NAACP and its Mississippi State Conference, sent a 60-day notice of intent to sue xAI over 27 unpermitted gas turbines in Southaven powering the Colossus 2 data center. · source

Colossus 2 — Under construction

Operator: SpaceXAI · Owner: SpaceXAI · Tenant: Anthropic, Cursor, SpaceXAI · Size: 946 MW

Chip types: B200,B300. Epoch AI estimates ~946 MW.

Next: Under construction — pull the approved conditions and permits and hold the builder to them; an expansion or a new building reopens the record.

Latest in the record

  • 2026-07-30 — The Mississippi Department of Environmental Quality issued an agreed order setting a retirement schedule for xAI's 69 temporary trailer-mounted turbines at the Southaven site, requiring decommissioning to begin August 18, 2026, with most units retired by April 2027 and the most recently added by July 14, 2027, after supply-chain delays to the 41 permanent turbines. · source
  • 2026-07-14 — Records obtained via public-records request (Trinity Consultants emails to Mississippi regulators) revealed xAI had operated 59 unpermitted gas turbines for Colossus 2, roughly double the 27 the company had publicly acknowledged in January, with at least 57 sited in Southaven, Mississippi. · source
  • 2026-06-15 — The U.S. Department of Justice moved to intervene in the NAACP lawsuit and asked the court to dismiss it, arguing that shutting off power to the Colossus 2 data center would harm national security because xAI's Grok supports Department of Defense military operations. · source

  • 2026-04-14 — The Mississippi State Conference of the NAACP and the national NAACP, represented by SELC and Earthjustice, filed suit against xAI and its subsidiary MZX Tech in the U.S. District Court for the Northern District of Mississippi, alleging illegal operation of unpermitted gas turbines under the Clean Air Act. · source
  • 2026-03-10 — The Mississippi Environmental Quality Permit Board unanimously granted xAI affiliate MZX Tech an air permit to install 41 methane gas-fired turbines at its Southaven facility, over community opposition. · source

Colossus 1 — Operating

Operator: SpaceXAI · Owner: SpaceXAI · Tenant: Anthropic · Size: 340 MW

Chip types: H100,H200,B200. Epoch AI estimates ~340 MW.

Next: Already operating — the leverage now is enforcement: noise and water conditions, tax revenue tracking, and any expansion filing, which reopens the record.

Latest in the record

As of August 2026 (2m ago) · changes weekly — re-check before citing

Illustrative rather than exhaustive — dozens of localities churn weekly, and this tracks the ones we have read a source for. **Each row carries its own provenance.** Rows showing a verification date link to the ordinance, the enacting body's own page, or a datable report of the vote, and were read on that date. Rows marked *unverified* came from bulk compilation and have not been checked against a primary source — the locality, the year, and the status may all be off. Verify one of those with the town clerk before citing it as precedent. **Expiry is derived, not asserted.** A row with a documented end date flips to *Expired* on its own once that date passes. A time-limited moratorium whose start date was never documented keeps showing as enacted — that is a known gap, not a claim that it is still in force. Moratoriums are also routinely extended, so an expiry date is the earliest it could have ended, not proof that it did.
