Tennessee
Tennessee escalated to a defining data-center state in 2026: the xAI/Memphis-Southaven pollution case is the highest-profile U.S. environmental-justice data-center fight (with the Trump DOJ intervening on xAI's side), the state enacted a 50 MW+ ratepayer-protection law taking effect in 2026, and a cascade of local moratoriums (Knox County through 2027, Nashville, McMinnville, Coffee, Washington and Moore counties) has emerged (Reuters DOJ/xAI; Route Fifty TN moratoriums).
ILens Signals
Civic/Governance Barriers activates on moratorium-class action (C1), meaningful 2026 race (C3), litigation/recall pathway (C4) — governance instruments on the electoral, legislative, and regulatory surface (protocol §10; Overview Civic breakout). Weather/Climate activates on extreme-heat large-load curtailment affecting power infrastructure (W3): U.S. DOE Federal Power Act §202(c) emergency orders in 2026 (including Nos. 202-26-23, 202-26-33, 202-26-33a, and 202-26-35) authorized PJM to direct ≥50 MW large loads — the hyperscale data-center profile — onto onsite backup generation during heat-wave reliability emergencies as a last resort before or during EEA Level 3 (DOE Order 202-26-23; DOE Order 202-26-35). Energy/Power dominant (xAI turbines potentially the largest industrial NOx source in the Memphis metro; TVA/grid demand). Capital Flows is a dominant stressor: Tennessee's 50 MW+ cost-allocation law is an explicit anti-cost-shift measure that assigns data-center grid costs to operators rather than existing ratepayers (Route Fifty). Water/Geology figures in Nashville's Metro Water Services review and local zoning studies (Tennessean).
IIKey 2026 Races
U.S. House, redrawn TN-9 (Memphis): the 2026 Tennessee redistricting cracked the majority-Black Memphis district and Democratic incumbent Steve Cohen ended his re-election bid; state Rep. Justin J. Pearson — who centers opposition to Memphis-area data-center pollution/power use (the xAI fight) — is running in the August 6, 2026 primary in a now-Republican-leaning seat (The Federalist Times/AP on Cohen; NPR redistricting; Integrity Index TN-9). Republican U.S. Sen. Marsha Blackburn, running for governor, urged reconsidering a Nashville data-center site near the zoo (Tennessean).
IIIMoratorium · Ban Status
No statewide moratorium, but a broad wave of local moratoriums: Knox County imposed a moratorium effective immediately through June 30, 2027 (extendable), with a 5 MW anti-avoidance threshold (Knox County resolution PDF); McMinnville passed an 18-month moratorium and Coffee County a moratorium (both June 9, 2026), with Warren County and Knox County votes advancing (Route Fifty); Washington County approved a one-year moratorium (March 24, 2026) (SuperTalk 92.9); Nashville's Metro Council advanced a moratorium bill (to Nov. 1, 2026) and Mayor Freddie O'Connell signed a supporting executive order (June 15, 2026) (Nashville Legistar; Tennessean).
IVRatepayer · Cost-Shift Legislation
Tennessee enacted a 2026 law requiring owners of data centers needing at least 50 MW to pay for any infrastructure upgrades needed to produce the electricity they demand; utilities may not use ratepayer funds for upgrades solely associated with data centers unless those upgrades also benefit other customers (Route Fifty). A related ratepayer-protection measure was reported to take effect in July 2026 (Local 3 News/WRCB via YouTube).
VBallot Measures
None identified. No Tennessee November 2026 statewide data-center ballot measure was certified; the fight runs through litigation, the legislature and local moratoriums rather than a ballot initiative (Route Fifty).
VITop Contested Sites
xAI Colossus 1 & 2 (South Memphis) / xAI-MZX Tech Southaven power plant: the flagship contested site. The NAACP sued under the Clean Air Act in April 2026 over 27+ (now ~57-59) unpermitted gas turbines; on June 15-16, 2026 the Trump DOJ moved to intervene and dismiss on national/energy-security grounds, and xAI, DOJ and Mississippi jointly seek dismissal (no ruling yet) (Reuters; AP). A proposed Nashville data center near the zoo is also contested (Tennessean).
VIITalent · Workforce
Construction/operations jobs are touted around xAI's Memphis buildout, but the salient labor/EJ dimension is community/environmental-justice organizing rather than construction-labor organizing; no distinct AI-displacement fight identified. Secondary context.
VIIIData Center Cluster Size
Growing, concentrated in Memphis (xAI Colossus 1 & 2, plus the adjacent Southaven, MS power plant/campus) with rising activity in Nashville and rural Middle/East Tennessee counties now imposing moratoriums (Knox, Coffee, Warren, Washington, Moore) (Route Fifty; Tennessean).
