Datacloud USA Thursday: ERCOT and Texas Power

Thursday, September 3, 2026, Austin Marriott Downtown. Capacity has now published a floor write-up from the 09:50 CT Texas panel. Meghan Griffiths, chairing for Jackson Walker, put ERCOT’s initial “batch zero” study at around 205GW of credible large-load demand against a current peak of around 91GW. Capacity does the arithmetic: that batch alone would be a 125% lift if realised in full. Those figures are Capacity’s attribution to Griffiths. They are not organizer briefing text, and they are not the session page’s 145GW line.

This is still the closing-day wire. The August 31 preview framed the week as compute meeting power. The Wednesday piece covered the AWS–OpenAI and CoreWeave clock. Capacity’s Saf Malik, dated 3 September 2026, is the first on-the-record recap Ultrathink has for Thursday’s Texas room. Session titles below remain agenda language. They are not quotes.

What Capacity recorded on Thursday

Capacity’s standfirst, attributed to panellists at the Texas keynote rather than to a named speaker, says ERCOT is reviewing roughly 474GW of large-load interconnection requests, with data centres around 90% of that queue. The Capacity page returned HTTP 200 at this update.

Griffiths, co-chair of Jackson Walker’s data-centre group, “told delegates” — Capacity’s verb — that ERCOT’s initial “batch zero” study estimates around 205GW of that demand as credible. She put current peak demand at around 91GW. Capacity’s same sentence frames that study as “now subject to a state-ordered audit.” The audit clause is Capacity’s characterization of the study, not a separate Griffiths quote printed as such.

Venkat Tirupati, ERCOT VP and CTO, did not, in Capacity’s piece, recite the session-page 145GW briefing. Capacity attributes this to him: ERCOT is embedding AI across its own operations, including efforts to accelerate interconnection studies, “with more than 800 of its roughly 1,000 employees now active users of AI tools internally.”

Senator Paul Bettencourt, per Capacity, called 2026 “the frothiest political year” of his career and tied rising local opposition to power use, water consumption, and land. Capacity has him saying Texas is home to 335 data centres supporting around 100,000 direct jobs and 400,000 indirect jobs, generating an estimated $65bn in annual economic activity, and that the industry has failed to communicate its resource use and footprint. On tax, Capacity reports he said the state’s data-centre sales-tax exemption, introduced around 2013 to 2015 at an estimated annual cost of $14.7m, now costs an estimated $3.3bn to $3.4bn a year, and that electricity-related subsidies specifically are likely to be scaled back or removed in the next legislative session.

Capacity, in the same Bettencourt paragraph but without a “he said,” notes Senate Bill 6, signed in 2025, already requires large loads of 75MW or more to disclose usage and comply with curtailment obligations during grid-stress events. Treat that statutory line as Capacity’s reported context, not a Bettencourt quote.

From the same Capacity recap, not as independent Ultrathink floor notes: Alex Hernandez, founder and CEO of PowerBridge, said he believes West Texas will become the largest data-centre market in the world, and that PowerBridge’s model is to build more generation than its campuses consume. Santiago Suinaga, SVP of cloud and hyperscale at Stream Data Centers, said the firm remains “very bullish” on Texas regardless of the audit’s outcome. Those are Capacity attributions.

What Capacity recorded on Wednesday

One earlier on-the-record floor interview is already out. Capacity’s Saf Malik, dated 2 September 2026, quotes Jonathan Mauck, Senior Managing Director at Digital Bridge Holdings, from Wednesday’s fireside. Mauck said data centres are built as 20-year industrial infrastructure, while the GPUs inside them last five to seven years. “You’re effectively a 20-year creditor,” he said. On Nvidia’s third-party compute-financing structures: “That looks like a version of round tripping my capital.” He also said inference growth is concentrating in smaller 20–40MW sites in tier-two and tier-three markets. Those are Wednesday remarks, attributed to Capacity. They are not Thursday speech.

Capacity’s recap is evidence the Texas panel spoke. Homepage speaker tiles naming Tirupati and Novak remain listings. They are not transcripts.

The 145GW line: briefing text, not a quote

The Texas session page, not a speaker, publishes this organizer copy: Texas data-center investment has been “attracted by competitive electricity prices, business-friendly policies, and rapid interconnection speeds,” and “ERCOT projects that peak summer power demand could approach 145GW by 2031, up from 85GW in 2024,” with over half projected from data centers. Treat the 145GW figure, the 85GW baseline, and the “over half” clause as session-page briefing. They are not attributed remarks from Tirupati or anyone else on that panel. Do not collapse them into Griffiths’ Capacity-attributed 205GW / 91GW / 125% lines. Different source, different number set.

Separately, ERCOT’s April 8, 2025 Long-Term Demand and Energy Forecast (the 2025 LTDEF PDF) lists a 2031 summer peak of 144,522 MW. That is official ERCOT paper, not a Thursday quote. The same table puts 2025 summer peak at 85,759 MW. The PDF, in the pages Ultrathink checked, does not assign “over half” of the 2031 peak to data centers. Do not collapse the session-page sentence into an ERCOT spoken line.

The organizer’s May LinkedIn notice that Tirupati would join the Texas panel is a speaker announcement. Promo copy, not a floor quote.

Two other Thursday rooms

Metro Connect Fall, Level 5, lists a 09:30–10:15 fiber keynote: “Are we returning to the connectivity-first model of DC site selection?” Official briefing: during the “AI power rush,” connectivity was “relegated” as power became the number-one site-selection driver. Speakers as published: Tricia Harvester, Oracle Cloud Infrastructure; Tom Spackman, Gigabit Fiber; Emilio Baez, Verizon; John White, US Signal; Lindon Hayes, Essentia. Chair: Andrej Danis, AlixPartners.

The Neocloud Leaders Forum & Breakfast, 09:30–11:30, Summit Room, Level 4, is invitation-only and under Chatham House rules. Topic 1 on the session page is “Power – Breaking through the power bottleneck.” Closed door. No quotes from that room belong here.

The main agenda also lists a 12:20–13:00 Datacloud USA-stage panel, “De-Risking the Power Bottleneck,” with Lockton, Salute, E2 Power, Corvex, and Parametrix. That page is sponsored session copy. Agenda language only.

Method

Ultrathink checked the official site, the 2026 agenda, the Thursday session pages listed below, the homepage speaker list, Capacity’s 3 September 2026 Texas-panel recap, Capacity’s September 2 Mauck interview, ERCOT’s 2025 LTDEF PDF, and the May Broad Group LinkedIn speaker notice. All returned HTTP 200. The Capacity Thursday piece is the source for the Griffiths, Tirupati, and Bettencourt lines above. This is an update to the existing Thursday wire, not a fourth Datacloud preview.
