SpaceX’s air registration for a gas-fired “Boca Chica Facility” near Brownsville, Texas, is listed as pending under registration number 185303, with a primary industry code for computer processing and data preparation, according to the TCEQ Central Registry record we read on 15 November. The registration, filed on 8 September and obtained by The 956 Report, describes 35 natural gas-fired turbines with a rated output of about 748 megawatts, the outlet reported.
That is about 1.8 times the roughly 422 MW of turbines that April 2025 aerial imagery showed at xAI’s Colossus site in Memphis, also 35 units, by our arithmetic on the figures The 956 Report cited. On Tuesday 17 November at 9:30 a.m., Cameron County commissioners take up an item to post a notice of intent to consider a Chapter 312 tax abatement for SpaceX (SPCX), the county agenda shows.
Business Pill · Vertical Integration
A short explainer on vertical integration: why owning more layers of the stack changes who takes a cut. It teaches the general idea and does not discuss SpaceX, Texas or the power plant.
The key insight: As we read the two records together, SpaceX’s Texas compute site is being permitted as a power plant first: the state lists a pending registration under a power-generation business with a data-processing code, and The 956 Report puts the filing at about 748 MW, about 1.8x the turbine capacity seen at Colossus in April 2025, by our arithmetic.
The Central Registry lists regulated entity RN112524897, “Boca Chica Facility”, in Cameron County near Brownsville, with Space Exploration Technologies Corp as owner and operator and a primary business of power generation. It carries two industry codes: NAICS 22111, electric power generation, and SIC 7374, computer processing and data preparation and processing services.
The entity’s one authorization is an air new source permits registration, number 185303, with the status pending. The San Antonio Express-News also reported that the Texas Commission on Environmental Quality lists the project’s air quality permitting as pending.
SpaceX said on 12 November that its roughly $24 billion data center in the Rio Grande Valley will generate its own electricity rather than draw from the grid, The Wall Street Journal reported. Our piece on SpaceX’s $74 billion compute plan covers that announcement.
Rated gas-turbine capacity in SpaceX’s TCEQ registration for the Boca Chica Facility (initial and final configurations), as reported by The 956 Report, against the roughly 422 MW of turbines that April 2025 aerial imagery showed at Colossus in Memphis, as cited by the same outlet. The 1.8x ratio is our arithmetic.
What the Filing Describes
The 956 Report said the registration, prepared by Trinity Consultants, seeks authorization under TCEQ’s standard permit for electric generating units. The initial configuration, which the filing calls temporary, lists six GE Vernova TM2500 (Plus) Gen 6 units at 25.4 MW each, two TM2500 (+G4) Gen 8 units at 27.4 MW, nine Mitsubishi FT8 units at 27.1 MW and 18 Solar SMT-130 units at 16.48 MW each.
A final configuration of eight GE Vernova 7E turbines at 88.56 MW each comes to about 708 MW, the outlet reported. The 18 Solar SMT-130 units supply about 40% of the initial 748 MW, by our arithmetic. The outlet said the projected start of construction and of operation are both listed as “TBD”, and that the filing describes the units as used or refurbished.
The outlet reported that the proposed cap on nitrogen oxides for the initial configuration is 248.86 tons a year, against the 250-ton federal threshold for a full major-source review. It added that the filing acknowledges construction and operation may not begin before TCEQ gives written approval.
The Colossus Comparison
The 956 Report wrote that at xAI’s Colossus supercomputer site in Memphis, aerial imagery in April 2025 showed 35 gas turbines totalling about 422 MW, including Solar SMT-130 units. SpaceX acquired xAI in February 2026, the outlet noted.
The Brownsville filing lists the same number of turbines and the same SMT-130 model. Its 748 MW against about 422 MW is 1.77 times, or about 1.8x, by our arithmetic. The Memphis figure is a count from April 2025 imagery, not a current figure for that campus; see our piece on SemiAnalysis’s Memphis estimate and on the city’s SpaceX AI fund.
The County Vote on 17 November
The Cameron County Commissioners’ Court agenda for Tuesday 17 November at 9:30 a.m. lists item H: authorisation to post a notice of intent to consider a Chapter 312 tax abatement agreement with Space Exploration Technologies Corporation, and to let the county judge sign the notice.
The 956 Report, which read the county’s three-page packet item, said the vote “is a vote to start the clock” and is not a vote on the tax break. It reported that the packet lists an estimated capital improvement cost of $17.9 billion, “estimated property tax values of $5.2 billion” and 500 new permanent jobs, with a county public hearing on Tuesday 29 December at 9:30 a.m.
The Rio Grande Valley Business Journal also reported the 17 November notice and a hearing and vote by 29 December, and quoted the packet saying the plant will “provide behind-the-meter power generation to limit the burden of new load on the Electric Reliability Council of Texas grid”.
As we read the sources, the money and the megawatts arrive through different doors: the county packet speaks of $17.9 billion and behind-the-meter power, Starbase’s notice of about $24 billion, and the state record of an air registration. None of the documents we read gives the computing capacity the plant would serve.
As we read The 956 Report’s account, the filing is built to be swapped: 35 used or refurbished turbines called temporary, to be replaced by eight GE Vernova 7E units at about 708 MW, with construction and operation dates listed as TBD.

Three Implications
FOR SPACEX The state record lists the Boca Chica Facility registration, number 185303, as pending; SpaceX said on 12 November the Texas data center will generate its own electricity, The Wall Street Journal reported.
FOR CAMERON COUNTY Commissioners take up notice of a Chapter 312 abatement on 17 November; The 956 Report says the county hearing is on 29 December.
FOR THE POWER QUESTION The 956 Report puts the initial configuration at about 748 MW across 35 turbines, about 1.8x the roughly 422 MW seen at Colossus in April 2025, by our arithmetic.
The framework says: “Companies that solve the power equation will dominate the AI era; those that don’t will watch their chips sit idle.”
As we read it, the Texas filing is SpaceX writing its own side of that equation: on-site gas turbines registered before any compute capacity is disclosed. The framework predates this filing and does not discuss SpaceX, Brownsville or Colossus.
What Is Not Established
We read the TCEQ registry record, not the registration itself. The turbine list, the ratings and the emission caps are The 956 Report’s account of the document it obtained; the Express-News matched the roughly 750-megawatt plant and the 35 turbines. The outlet said the filing does not mention a data center.
The county packet gives no abatement percentage or term, according to The 956 Report, and the 17 November item does not decide the abatement. The 422 MW Memphis figure dates from April 2025. We did not contact SpaceX or Cameron County for this piece.
This Week In The AI Supercycle
AI Lost Its Central Banker, the Lab Oligopoly, and the Future of Open Source
This week’s issue: the Nvidia leadership change, read as the AI build-out losing its central banker: who now finances the GPU landlords, backstops the data centres and sponsors open models, and why two labs are becoming the bank.
TCEQ lists SpaceX’s Boca Chica Facility air registration 185303 as pending, under a data-processing industry code. The 956 Report says the filing covers 35 turbines and about 748 MW, about 1.8x the turbine capacity seen at Colossus in April 2025, by our arithmetic. Cameron County takes up notice of a tax abatement on 17 November, with a hearing set for 29 December, according to The 956 Report.
A note on sourcing. The registration number, status, owner and industry codes are from the TCEQ Central Registry record for RN112524897, which we read on 15 November 2026. The turbine list, ratings, emission caps and the Memphis imagery figure are from The 956 Report, which obtained SpaceX’s 8 September registration; we have not read the registration itself. The county item is from the Cameron County agenda; packet figures are from The 956 Report. Ratios are our arithmetic. We did not contact SpaceX or Cameron County.
