Abbott Resets Texas Datacenter Rules as ERCOT Queue Hits 438 GW

Abbott just changed the terms of trade in Texas. A June 10 directive ordering the PUCT and ERCOT to keep datacenter transmission costs off residential bills, with a July 17 interim memo and a July 31 PUCT measure deadline, lands on top of an ERCOT queue that's grown from 24 large-load requests two years ago to 519 totaling 438,595 MW. That's roughly a third of all U.S. generation capacity chasing Texas dirt. The political weather shifted mid-week, and the developers who'd already locked anchor tenants, generation, and water moved up the line while the rest started doing math.

The Queue Sorted Itself The week opened with [ERCOT's Batch Zero proposal](https://hyperscalenews.com/briefings/2026-06-08/anchor-tenant-signed-lease-locked-power-ercots-new-cost-of-entry) requiring deposits, a contracted customer, and a signed lease before advancing. By Tuesday, **AEP**'s 30 GW-to-5.6 GW collapse showed [what deliverable demand actually looks like](https://hyperscalenews.com/briefings/2026-06-09/deliverable-demand-is-the-new-dividing-line-in-ercots-queue) once financial commitments tighten: an 81% cut. By week's end, **Black Hills Corp.** had secured [over $200 million in refundable upfront contributions](https://hyperscalenews.com/briefings/2026-06-13/hyperscalers-wire-200m-upfront-as-ercots-queue-hits-438-gw) from an undisclosed hyperscaler for a 1.8 GW 2028 load. The bypass playbook hardened:

• •Google/Intersect Power's 1+ GW Meitner campus in Gray and Roberts Counties, self-supplied wind/solar/storage
• •CyrusOne's 380 MW Freestone groundbreaking behind Calpine's gas plant, 760 MW Constellation contracted
• •Hut 8's 1,000 MW Beacon Point in Nueces County, $4.25B financing, developer-funded substation
• •Oracle's 2.45 GW Bloom fuel-cell deal for OpenAI's Project Jupiter

Water Moved From Cooling Math to Power Procurement Math Monday's framing treated water as a county-permit problem. By [Wednesday](https://hyperscalenews.com/briefings/2026-06-10/418-gw-knock-on-texas-doors-behind-the-meter-builders-skip-the-line), Xylem/GWI data reframed it: cooling is only 4% of AI's water through 2050, generation takes 54%, fab takes 42%. That's why **Meta**'s $10B El Paso campus paired closed-loop cooling with a 200% restoration pledge funding 177M gallons annually. It's why **Texas Pacific Land Corp.** closed a $42.5M land deal tied to a treated produced-water supply agreement. Developers leading with cooling efficiency alone won't clear regulations written for the bigger number. The ones structuring produced-water deals before TCEQ finalizes a classification pathway are buying optionality nobody else can replicate.

The Authority Gap Drives Action to Austin Counties don't have the statutory tools, and they know it. Parker County Attorney **John Forrest** said it plainly on June 9. Hill County's moratorium drew a $100M lawsuit and got rescinded. Hood County's plat denials are in litigation. That vacuum is exactly why [Abbott's directive](https://hyperscalenews.com/briefings/2026-06-12/self-generation-disclosure-and-a-2027-deadline-abbott-resets-the-terms) carries weight: it previews a 2027 agenda repealing the $3.3B sales-tax exemption, mandating water and electricity reporting, and requiring closed-loop cooling. **Ohio HB 646** already cut its exemption from 100% to 50% and mandated self-generation above 250 MW. PUCT Chairman **Gleeson** backed Abbott; the Data Center Coalition signaled engagement. The drafting window is open between now and the July 17 memo. Developers who file written PUCT comments and meet with Senate interim committee staff during Patrick's [study hearings](https://hyperscalenews.com/briefings/2026-06-11/abbott-names-july-17-the-2027-rulebook-starts-getting-written-now) shape definitions of "deliverable demand," cost-allocation triggers, and water-reporting thresholds. The ones who wait inherit definitions written by people who've never sequenced an anchor tenant deal.

What to Watch - **July 17**: PUCT/ERCOT interim memo to Abbott on authority gaps and legislative recommendations - **July 31**: PUCT transmission cost allocation measures finalized, the first concrete test of cost-shifting mechanics - **TCEQ produced-water classification**: the unresolved permit pathway is both the Permian's constraint and its largest competitive moat - **Senate interim study hearings** under Lt. Gov. Patrick: the rulemaking record that 2027 legislation will cite
