Control No. 58481 Puts $50K/MW Floor Before ERCOT Models 1 GW

The Public Utility Commission of Texas adopted new §25.194 on September 11, 2026 under Control No. 58481, locking SB 6's large-load framework into rule. A large-load customer must post $50,000 per MW in financial security before any interconnection study: $50M on a 1 GW campus before ERCOT models the load.

Intermediate agreements, material-fact disclosures, a standard large load interconnection agreement at construction, updated security, and contribution in aid of construction now sit on a defined path, with security held through energization and forfeiture language on withdrawal or false disclosures. Capital planning just got a hard floor; CIAC ranges by zone remain the second line item developers still have to price before site lock.

Pennsylvania Governor Josh Shapiro's GRID executive order (August 18) creates a two-tier path for projects over 25 MW: sign a template Consent Order and Agreement for rolling DEP review and the equipment tax exemption, or take standard timelines with no incentive. Developers must build, bring, or buy incremental capacity inside the same PJM locational deliverability area and carry full upgrade costs; a stepped firm-resource share starts January 1, 2027. Pending SB 1359 (statewide moratorium) and SB 1345 (municipal opt-out up to 18 months) have not passed.

New York Governor Kathy Hochul ordered a one-year construction pause in July. A Kentucky circuit court will hear standing under House Bill 321 in October after TenKey LandCo's Franklin campus approval drew a citizens suit the developer moved to dismiss. An EPA proposal would make public notice and comment optional on minor-source air permits, shifting that call to states. These are cautionary site-selection signals: Texas still draws capital on queue speed and clear cost rules, and prepared operators treat out-of-state friction as diligence on tariffs, community agreements, and self-supplied power sequencing.

ERCOT was tracking 474 GW of data-center requests as of August 3 against a 91.13 GW all-time peak, with data centers roughly 90% of the queue. Governor Greg Abbott ordered ERCOT and the PUCT to audit large-load applicants on ownership, load, on-site generation, incentives, water, cooling, and community impact before Batch Zero advances speculative paper.

Comparable utility filters compressed hard elsewhere: AEP Ohio saw 30 GW of proposals fall to 5.64 GW once studies, service agreements, and collateral were required; Exelon high-probability demand dropped nearly 40%, to about 11 GW, with roughly 4 GW backed by about $1B in collateral. Bitdeer paid $100M for 200 acres beside its Rockdale site in Milam County, Texas, consolidating access to 563 MW interconnected capacity with a stated path to 742 MW on owned land already tied to transmission.

Vertiv is paying $1.45B cash (up to $1.15B more in earnouts) for UtilityInnovation Group's microgrid controls and storage orchestration so operators can sequence grid-connected, bridge, or islanded power from site selection. Tersis Technologies and Flux Core signed a non-binding MoU to pair 10-30 MW waste-to-energy modules with modular compute against a 120-180 MW Tersis pipeline. One Nuclear Energy locked a binding LOI for a 2.88 GW gas plant plus 700 MW of four-hour BESS for an undisclosed Louisiana data-center campus near RiverPlex in Ascension Parish, with public meetings planned through year-end.

Bottom line: post the $50K/MW early, price CIAC by zone, and sequence owned or behind-the-meter capacity on sites that already clear the audit screen, or carry the cost of a forfeited queue slot measured in quarters.

NC State hydrologist Matthias Sprenger flags open-loop evaporative cooling as one-way extraction: millions of gallons per day leave as vapor, blowdown raises salinity and biocide load, and the demand cannot flex in drought the way municipal use can. Indirect water embedded in generation and chip manufacturing sits outside most community impact studies.

The Texas Water Development Board mailed mandatory questionnaires to 341 operators in January and had 100 responses by late August, a 30% rate that leaves the five-year water-demand forecast under-built on cooling load. TWDB director of water supply planning Temple McKinnon told the Senate Water, Agriculture, and Rural Affairs Committee contacts and compliance remain uncertain; PUCT executive director Connie Corona cited confidentiality pushback. Senator Charles Perry rejected the trade-secret frame: water is a public resource, and a business model that treats it as proprietary has to change.

Bottom line: map watershed capacity and closed-loop or recycled cooling before land option, and file the TWDB survey now so the next planning cycle is written from operator data rather than gaps.

A March 2026 Gallup poll found 71% of U.S. adults oppose new AI data centers nearby; AdImpact pegged 8% of July broadcast campaign spend to data-center or AI themes, 99% of it attack copy. President Trump still backs buildout and has said communities that resist risk being left behind, while a senior White House official said he wants projects only where communities want them and wants operators to pay their own power and water.

Brian Janous of Cloverleaf Infrastructure, on Latitude Media's Catalyst, split the backlash into solvable cost problems (substations, tariffs, water offsets) and values fights that engineering cannot design away. Tractable grievances reward developers who fund their own upgrades and structure industrial loads to carry their own cost; ideological opposition pushes more load toward private generation and longer capital cycles. Texas has no statewide pause, but rural and suburban opposition is live where rates and water already bite.

Bottom line: front-load benefit-sharing, tariff design, and water-offset proof with the same rigor as interconnection security, or budget for self-supplied power and multi-quarter delay when consent fails.
