2026-07-24 — Opened + crawled

• Thread opened (ben-steer). ⟨steer 2026-07-24⟩
• Verdict: severe, worsening, multi-dimensional — power is the gating factor. The defining escalation is legal-political: the DOJ now invokes national security to keep unpermitted turbines running against a citizen Clean Air Act suit — the improvisation has outrun the regulatory system. ⚠ WebSearch budget exhausted (fan-out) — flagship + high-value claims re-verified via fetch; some figures RSS-only, flagged. ⟨crawl 2026-07-24⟩

2026-07 — The equipment ceiling + the ratepayer bill

• GE Vernova’s gas-turbine backlog hit 116 GW, sold out through 2030 ($176B total backlog, data-center orders >$5B YTD = 2x all of 2025) — even self-supply can’t scale fast. Same week, PJM’s market monitor: data centers drove 38% of the latest capacity-auction charges (46% across four auctions); the 2028/29 auction cleared at the $325/MW-day price cap; FERC’s chair warned PJM faces a “grave legitimacy crisis.” (GE Vernova) ⟨crawl 2026-07-24⟩

2026-06-16 — The DOJ national-security shield

• The Trump DOJ moved to dismiss the NAACP Clean Air Act suit on national-security grounds — arguing shutting the 57 unpermitted Southaven turbines threatens security because Grok “supports Department of War operations” (a DoD official called Grok “paramount national security,” citing the Iran strikes). Converts an environmental-permitting fight into a federal-power question. Cross-refs spacex-colossus. (NYT) ⟨crawl 2026-07-24⟩

2026-04 — Improvising around the grid, at scale

• Meta’s “Hyperion” got ~7 new gas plants fast-tracked in Louisiana (Entergy +$14B capex; a later ratepayer-protection order); NAACP/SELC/ Earthjustice sued xAI over 27 unpermitted methane turbines (~495 MW, alleged 1,700+ t/yr NOx) at Southaven — “a de facto power plant without an air permit,” in a historically Black neighborhood leading TN in asthma.

2026-01 — EPA: the turbines ran illegally

• EPA ruled xAI’s Memphis turbines ran illegally under a bogus “temporary” exemption — 35 operated, only 15 permitted. Memphis is really two braided sites: Colossus 1 (Boxtown, TN) + Colossus 2 (Southaven, MS). (TechCrunch) ⟨crawl 2026-07-24⟩

Backstory — the queue + the equipment wall

• ERCOT’s large-load queue hit ~438 GW (+~300% YoY); large-transformer lead times are ~2.5–3yr (vs 4–6 weeks pre-pandemic), Wood Mackenzie projected a 30% transformer supply deficit; AEP Ohio’s landmark data-center tariff (07-2025) is the template other states now copy (make data centers pay for their minimum contracted power). ⚠ ERCOT 438GW + transformer figures RSS/secondary-sourced. ⟨crawl 2026-07-24⟩
