Fermi America has filed to build four Westinghouse AP1000 nuclear reactors in Texas as the backbone of what the company calls an 11-gigawatt private power campus. The Nuclear Regulatory Commission accepted the combined license application for review, and the Texas Commission on Environmental Quality issued a Clean Air Permit covering roughly 6 gigawatts of gas-fired generation at the same site. If the project advances on schedule, it would represent the largest single private power complex ever proposed in the United States, blending nuclear, natural gas, solar, and battery storage at a moment when Texas electricity demand is climbing fast.
Why the 11 GW Project Matador filing changes the Texas power calculus
The immediate tension is timing. Fermi America submitted a Part 52 combined license application for four AP1000 units, designated Units 1 through 4, under the project name “Advanced Energy and Intelligence Campus.” The NRC has formally accepted Parts 1 and 2 of that application for review, as reflected in the agency’s new-reactor docket. But the agency has not published a review schedule with safety or environmental milestones, which means the nuclear portion of the campus has no confirmed operational date.
That gap matters because Texas data-center construction is accelerating and the state grid operator, ERCOT, has been warning about thinning reserve margins during peak summer demand. The four AP1000 reactors, each rated at roughly 1,100 megawatts, would provide firm baseload power that solar and wind cannot guarantee during evening peaks or extended calm-weather periods. If the NRC review stretches beyond the late 2020s, the nuclear capacity would arrive after the period when Texas load growth is expected to strain existing supply most acutely. Gas turbines can be built faster, which explains why Fermi America pursued state air permits for 6 GW of gas generation in parallel.
For industrial customers and data-center developers, the difference between gas and nuclear timelines is material. A gas-heavy buildout could support near-term server farm expansion but would lock in higher emissions and fuel-price exposure. Nuclear units, if eventually licensed and constructed, could provide decades of relatively stable, carbon-free power but will not solve the immediate capacity crunch. The company’s choice to advance both tracks simultaneously reflects that tradeoff.
Permits, filings, and the generation mix behind the campus
Two regulatory tracks are running simultaneously. On the federal side, the NRC is conducting its National Environmental Policy Act process to decide whether to issue combined operating licenses for the four AP1000 units designated PMN Units 1 through 4. That review includes scoping for an environmental impact statement, public comment periods, and a safety evaluation, as outlined on the agency’s environmental review page, none of which have published completion targets.
On the state side, the TCEQ issued Permit 2025-1898-AIR for Fermi America’s Project Matador site. According to a Fermi Inc. quarterly filing, the final approval date for the roughly 6 GW Clean Air Permit was Feb. 25, 2026. Fermi America’s own announcement described the permit as covering 6 GW of gas-based generation and called the campus “the world’s largest 11 GW private power grid,” a characterization repeated in a press release. The company stated the full generation mix would include natural gas, advanced nuclear, solar, battery storage, and utility grid power.
A small discrepancy exists between those two accounts. The SEC filing pins the TCEQ approval to a specific February 2026 date, while the company press release frames the permit as already “secured” without specifying the same date. Both documents point to the same permit, but the difference in framing means readers should treat the exact approval timeline as confirmed by the SEC disclosure rather than the promotional announcement alone.
The same SEC filing references a Collaboration Agreement with Texas Tech University, though the public text of that agreement and its scope of work have not been disclosed. No primary NRC or TCEQ document details the planned solar or battery capacities, their megawatt ratings, or their grid interconnection points. The 11 GW total, therefore, rests on Fermi America’s own accounting of combined generation sources, not on independently verified engineering documents.
That distinction is important when comparing Project Matador to existing power complexes. Measured strictly by licensed nameplate capacity, only the 6 GW of gas turbines and the four proposed nuclear units have formal regulatory footprints. The remaining megawatts, while plausible given the site’s size and the company’s ambitions, remain conceptual until separate interconnection studies, land-use approvals, and construction contracts are made public.
Unresolved questions facing Fermi America’s nuclear and gas buildout
Several critical unknowns hang over the project. First, the NRC acceptance letter confirms the application is under review but contains no schedule for completing the safety evaluation or environmental impact statement. Previous AP1000 reviews at other sites took years longer than initially projected, often due to design changes and post-Fukushima requirements. Without a published timeline, the nuclear portion of the campus cannot be reliably slotted into any demand forecast, leaving utilities and large customers to plan around a moving target.
Second, the TCEQ permit order addresses gas-fired units and site coordinates but includes no conditions tied to co-located nuclear operations. That means the gas and nuclear tracks are legally independent. Fermi America could, in theory, build and operate 6 GW of gas generation without ever completing the nuclear reactors, which would fundamentally change the emissions profile the company has marketed. It would also alter the project’s risk balance: investors would be exposed primarily to fuel and carbon policy risks rather than construction and licensing risks associated with new nuclear.
Third, the 11 GW headline figure bundles sources with very different construction timelines and regulatory pathways. Gas turbines can reach commercial operation within two to three years of permitting. Utility-scale solar farms typically take 18 to 24 months from interconnection approval to energization. Nuclear reactors, even with a design already certified by the NRC like the AP1000, face multi-year construction periods and extensive oversight before fuel loading. Batteries add another layer of complexity, with siting and fire-safety standards still evolving in many jurisdictions.
These mismatched timelines raise questions about how the campus will be phased. One plausible sequence is a first wave of gas units and batteries to serve early data-center load, followed by solar additions, with nuclear units arriving last if and when licenses are granted. That would create a shifting generation mix over a decade or more, making it difficult for regulators and communities to evaluate long-term impacts based on today’s marketing materials.
Local infrastructure is another open issue. High-voltage transmission upgrades, water supply for both gas and nuclear units, and workforce housing could all become constraints if multiple gigawatts come online in a compressed window. None of those supporting elements are detailed in the NRC or TCEQ documents referenced so far, leaving gaps in the public picture of how the campus would integrate into the broader Texas grid and local economy.
What to watch as Project Matador moves forward
In the near term, the most telling milestones will be procedural rather than physical. On the federal side, the publication of a draft environmental impact statement and a projected completion date for the safety evaluation will offer the first concrete signals of how quickly the nuclear units could move. On the state side, any amendments to the TCEQ permit, especially changes to emissions limits or turbine counts, will clarify whether Fermi America intends to lean more heavily on gas than its initial messaging suggests.
Potential customers will also drive outcomes. Long-term power purchase agreements from hyperscale data-center operators or industrial users could underpin financing for both gas and nuclear phases. Conversely, if buyers insist on near-term, low-carbon power, Fermi America may face pressure to accelerate non-emitting capacity or pair gas units with carbon mitigation strategies.
For now, Project Matador stands as an unusually large bet that Texas’s appetite for electricity will keep rising and that regulators will ultimately clear both conventional and advanced generation on a single, privately controlled campus. Whether that bet reshapes the state’s power mix-or simply adds another cluster of gas plants with nuclear still on the drawing board-will depend on how the unresolved questions outlined here are answered over the rest of the decade.
