SpaceX Starbase Super-Compute: Fiber and RFP Watch

Written by Chris Nunez

The City of Starbase, Texas, has set a public hearing on a property tax abatement for a large SpaceX project east of Brownsville. For telecom carriers, fiber optic providers and broadband sales teams that already work the Rio Grande Valley, the notice is worth reading: it pairs on-site power with a “super-compute facility” on roughly 444 acres between Boca Chica Boulevard and the Port of Brownsville.

Nothing in the notice is an approval. It only schedules the City Commission to consider two agreements at a regular meeting.

What the Starbase public notice says

According to the City of Starbase’s Notice of Public Hearing:

  • Who: Space Exploration Technologies Corp., a Texas corporation (“SpaceX”), is both the property owner and the applicant.
  • When and where: Wednesday, December 9, 2026, at 7:00 p.m., at 48491 State Highway 4, Starbase, Texas 78521.
  • Agreements under review: a property tax abatement under Chapter 312 of the Texas Tax Code, and a related economic development agreement under Chapter 380 of the Texas Local Government Code.
  • Zone: the Cameron County Enterprise Zone, which under Tex. Tax Code § 312.2011 counts as a reinvestment zone for Chapter 312.
  • Site: an approximately 444-acre tract inside Starbase city limits in Cameron County, just east of Brownsville, between Boca Chica Blvd and the Port of Brownsville, currently Cameron County Property ID# 171887.
  • Project: SpaceX “proposes to construct, own, and operate a gas-fired power plant and super-compute facility.”
  • Investment: estimated capital investment for initial phases is approximately $24 billion, which “may be constructed over multiple phases and include future expansions.”
  • Public comment: interested persons are invited to attend and be heard (Tex. Tax Code § 312.207(d); Texas Government Code Chapter 551).

The notice does not state megawatts, job counts, abatement percentage or term, water use, construction dates, or fiber interconnect details.

Local reporting says the city posted the notice on Friday, November 6, 2026 (The 956 Report; Gateway to Mars). Gateway to Mars also reports the tract matches about 444.46 acres Starbase annexed on a SpaceX petition on September 21, 2026, and that a Starbase building-permit log lists a SpaceX application at “40193 TX 4 Data Center” described as “444 Acres.”

Power scale reported in a separate TCEQ filing

The city notice itself does not give generating capacity. The 956 Report (Nov. 3, 2026) describes a pending TCEQ air registration for SpaceX’s “Boca Chica Facility,” filed September 8, 2026. According to that reporting on the filing: an initial, temporary configuration of 35 natural gas turbines totaling about 748 MW; a later configuration of eight GE Vernova 7E turbines totaling about 708 MW; primary SIC code 7374 (computer processing and data preparation services); and construction and operation starts listed as TBD. Those figures are configurations in a pending air filing, not an approved final plant design.

Why this matters for telecom, broadband and fiber teams

A gas plant next to a large compute campus changes the demand picture for fiber optic and broadband infrastructure even while the tax vote is pending.

Backhaul and middle-mile near the Port. Hyperscale or “super-compute” campuses typically need diverse, high-capacity routes to carrier hotels, internet exchanges and long-haul paths out of the Valley. Providers with lit or dark fiber along Boca Chica Blvd, State Highway 4, the Port of Brownsville corridor, or routes toward Harlingen and McAllen should map proximity to Property ID 171887 before treating the site as out of market.

Construction RFQs and adjacent public demand. Multi-phase builds of this size often generate RFQs for OSP fiber, conduit, splice work and temporary construction connectivity. Nearby schools, libraries and clinics may also drive E-Rate, RHC, state broadband or municipal RFP notices. GIS mapping of fiber against applicant sites remains the practical screen before a bid.

Watch the facts, not the rumors. The notice does not name the compute customer, ERCOT interconnection, or cooling design. Do not price a circuit on megawatt rumors alone. The abatement has not been approved.

The political angle: a new governor and a permit pause

The tax vote is local, but the harder approvals are at the state level, and Texas politics just shifted.

A pause already in place. On August 3, 2026, Gov. Greg Abbott halted new data center connections to the ERCOT grid, suspended ERCOT's "Batch Zero" interconnection work, and directed state environmental regulators to pause permits for data center-related projects until an ERCOT audit is complete. ERCOT expects that audit by December 10 (S&P Global; Reuters via Investing.com). A gas plant's air permit comes from TCEQ, the same agency covered by that pause.

A governor-elect who campaigned on a moratorium. Democrat Gina Hinojosa defeated Abbott on November 3 and takes office in January. On the campaign trail she said she would issue "a ban on all data center approvals until laws can be passed by the Legislature to protect Texans," and she has called for ending data center tax subsidies, protecting water supplies, and making large loads pay for their own electricity (Texas Tribune).

Not a lone project. S&P Global reports Texas has 32 proposed gas-fired projects to power data centers, and a Texas Politics Project poll found 56% of Texas voters oppose data center construction.

What this means: the December 9 abatement can move forward locally, but the air permit, grid interconnection and any state incentives may face a slower, more political path in 2027. For fiber and broadband teams, that argues for mapping the corridor now and bidding on firm RFQs, not on timelines.

How to watch the corridor with Map4

Pin the Starbase / Port of Brownsville corridor on the Map4 National Map, score nearby fiber providers by nearest route or coverage, and overlay open telecom RFPs—including E-Rate, state, federal and organic—so your team sees opportunities in proximity to the site as they appear.
