McMinnville and Coffee County, Tennessee each unanimously passed data center moratoriums on June 9. Nashville's Metropolitan Council followed the same evening, advancing a 90-day pause on all data center permits across Davidson County by a 26-to-1 vote. Warren County and Knox County are scheduled to vote June 22. Since last fall, nine Tennessee cities and counties have enacted moratoriums; five passed in a single week.
The Nashville pause runs until November 2026 or until new zoning ordinances take effect. Mayor Freddie O'Connell signed Executive Order 59, directing Metro departments to identify protections for air, water, public spaces, and residents. The order sets a threshold: any facility above 20,000 square feet or drawing more than 5 MW of electrical demand qualifies as a large data center subject to review. Existing facilities are unaffected.
Two specific projects triggered Nashville's action. DC Blox proposed a 69,000-square-foot, 10 MW Phase 1 data center adjacent to the Nashville Zoo, with permits already filed for a 202,000-square-foot, 40 MW Phase 2 building on the same site. A second proposal at Fisk University would mix 30,000 square feet of academic space with a 70,000-square-foot technology center. More than 360,000 people signed a petition against the zoo-adjacent site. McMinnville's catalyst was a 96,064-square-foot, 25 MW facility from Hixson powered by natural gas and diesel generators announced publicly without filing permits. The city passed an 18-month moratorium.
Tennessee's rural counties signal a broader trend. A Pew Research report from April 2026 found that nearly 90% of existing U.S. data centers are in urban areas, but 67% of planned new centers target rural locations — drawn by cheaper land, lenient zoning, and no state income tax. In Tennessee, 61 data centers are operating or under construction statewide: 26 in Nashville metro, 13 in Memphis, 11 in Knoxville, 5 in Chattanooga. Yet counties attracting build-outs have the thinnest regulatory infrastructure to assess grid, water, and noise impact. McMinnville City Administrator Nolan Ming said: "A moratorium is not a permanent ban. It is a responsible time-out."
The pattern is national. As of May 2026, 69 jurisdictions have enacted data center moratoriums. New York's legislature passed a one-year freeze on large facilities pending gubernatorial signature. Seattle imposed a one-year pause. Maine's legislature passed a moratorium through October 2027 before the governor vetoed it over a single Franklin County project. According to Data Center Watch, a project of AI research firm 10a Labs that tracks local data center development, at least 75 data center build-outs worth around $130 billion were blocked or delayed in Q1 2026 alone — matching the total disruption of all 2025 compressed into three months. No U.S. state has enacted a permanent ban, but municipal fragmentation complicates multi-region capacity planning.
For architects sizing inference clusters or negotiating colocation capacity, Tennessee introduces two concrete friction points. First, the 5 MW threshold in Nashville's order falls below the draw of a single dense GPU rack row at scale. NVIDIA's DGX SuperPOD reference architecture documents power consumption per rack exceeding 40 kW with four DGX H100 systems, and industry benchmarks put a row of four to eight H100-class servers at 40–80 kW. A 64-rack deployment crosses 5 MW before cooling overhead. Second, the 18-month McMinnville moratorium and 90-day Nashville window misalign with data center procurement timelines of 12–24 months from site selection to energization. A permit freeze mid-process can strand interconnect agreements and utility contracts already signed.
Rural Tennessee is no longer a low-friction alternative to saturated Ashburn or Phoenix campuses. Site selection must now gate on local zoning and community-opposition risk before issuing an RFP.
