Nuclear Power & SMRs for Data Centers, Explained
Amazon, Google, Meta, and Microsoft have collectively committed to roughly 9.8 GW of nuclear and small modular reactor capacity as of mid-2026 — but almost none of it involves buying raw land the way a grid-connected or gas-powered site does. Here's what the nuclear buildout actually means, and why it isn't the power strategy most landowners should be planning around.
⚡ TL;DR — What to Know About Nuclear & SMRs for Data Centers
- • Scale: ~9.8 GW in publicly announced hyperscaler nuclear/SMR commitments across Amazon, Google, Meta, and Microsoft as of mid-2026
- • Why now: 24/7 baseload output without renewable intermittency or a multi-year grid interconnection queue
- • Real deals: Meta/TerraPower (up to 8 Natrium SMR plants, Jan. 2026); Amazon/X-energy/KHNP/Doosan ($50B target for reactors and supply chain); Google (three sites, ~600 MW each, twin 300 MW SMRs)
- • Site reality: nearly all current deals are co-located at existing licensed nuclear sites or run through established utility developers — not new land
- • Timeline: NRC licensing plus construction typically runs years longer than a standard grid interconnection
The Deals That Are Actually Happening
Meta / TerraPower
January 2026 agreement for up to eight Natrium sodium-cooled fast reactor plants. Meta's total nuclear commitments — across TerraPower, Oklo, Vistra, and Constellation — reach as high as 6.6 GW.
Amazon / X-energy Partnership
August 2025 partnership with X-energy, Korea Hydro & Nuclear Power, and Doosan Enerbility, targeting up to $50 billion in public and private investment to accelerate SMR deployment and build out the domestic supply chain.
Google Advanced Nuclear Sites
Agreement to prepare three separate sites for advanced nuclear projects, each planned around 600 MW — likely delivered as twin 300 MW SMR units per site rather than a single large reactor.
Plant Restarts & Refueling
Beyond new SMRs, utilities are extending life on existing nuclear assets — PSEG's Hope Creek refueling in New Jersey, for instance — as a faster path to added baseload capacity than any greenfield nuclear project.

Why Your Raw Land Almost Certainly Isn't an SMR Candidate
This is worth being direct about, because the nuclear headlines can create unrealistic expectations for landowners with no prior connection to the sector. Every major SMR deal announced so far is structured one of two ways: co-located at or immediately adjacent to an existing licensed nuclear facility, which lets the developer leverage existing site infrastructure, security, and — critically — a faster regulatory path than a true greenfield site would require; or run through an established utility-scale nuclear developer with the balance sheet and in-house licensing expertise to carry a multi-year Nuclear Regulatory Commission approval process from start to finish.
A parcel with no prior nuclear or major utility-generation history doesn't meet either of those conditions, no matter how much acreage it has or how close it sits to a transmission line. That's a meaningfully different bar than what qualifies land for grid interconnection or even behind-the-meter gas generation — see our guide to on-site and behind-the-meter power for the power strategy that's actually accessible to most landowners today.
The Timeline Problem
Even with SMR designs built around standardized, factory-manufactured components, NRC licensing for a new reactor and site commonly adds several years on top of construction — on a timeline that's already longer than most grid interconnection studies. That's why the fastest-moving nuclear commitments right now aren't new construction at all; they're plant restarts and fuel-cycle extensions on existing licensed capacity, since that path skips the years-long new-site licensing process entirely. For a developer racing to meet near-term AI compute demand, a new SMR is closer to a multi-year, next-cycle bet than a solution to this year's power gap.
What this actually means for site selection today
The nuclear buildout matters most as an indirect signal, not a direct opportunity. A utility investing in nuclear capacity — refueling an existing plant, extending a fuel cycle, or signing an SMR development partnership — is telling the market it's building ahead of large-load demand rather than simply letting the interconnection queue back up indefinitely. That's a genuinely favorable signal for grid-connected sites in that utility's territory, even though none of the actual nuclear megawatts are likely to reach a specific unconnected parcel. If you're marketing land, a utility's nuclear investment plans are worth noting as context — but the power fundamentals that actually determine your site's fit remain the same: substation proximity, deliverable grid capacity, and (in some markets) natural gas access for behind-the-meter generation.
Frequently Asked Questions
Why are tech companies suddenly signing nuclear power deals for data centers?
Baseload reliability at scale, mainly. Solar and wind are cheaper to build but intermittent; grid interconnection for any power source can take years; and gas turbines, while faster to site, carry emissions commitments many hyperscalers have publicly walked back on rather than abandoned outright. Nuclear — whether an existing plant or a newly built small modular reactor — offers 24/7 baseload output without the intermittency of renewables or the queue delays of new grid transmission, which matters more as AI training and inference loads grow larger and steadier. Across Amazon, Google, Meta, and Microsoft, publicly announced nuclear and SMR commitments totaled roughly 9.8 GW by mid-2026.
What exactly is a small modular reactor (SMR)?
A nuclear reactor design built at a smaller scale than a traditional gigawatt-class plant — typically in the 50–300 MW range per unit — manufactured with more standardized, factory-built components intended to reduce construction time and cost compared to conventional nuclear builds. Meta's January 2026 agreement with TerraPower for up to eight Natrium reactor plants and Amazon's 2025 partnership with X-energy, Korea Hydro & Nuclear Power, and Doosan Enerbility (aiming to attract up to $50 billion in reactor and supply-chain investment) are both built around this SMR model rather than traditional large-scale nuclear construction.
Does this mean a landowner's raw land could become an SMR site?
Almost certainly not, at least under current deal structures — and this is the most important thing for a landowner to understand before getting excited about nuclear headlines. Nearly every announced hyperscaler nuclear deal is either co-located at or adjacent to an existing licensed nuclear facility (leveraging existing site infrastructure and a faster regulatory path) or tied to a utility-scale developer with the balance-sheet and licensing capacity to run a years-long NRC approval process. A parcel with no prior nuclear or major utility-generation history is not a realistic SMR candidate on its own merits, regardless of how much acreage or power-adjacent positioning it has.
How long does it actually take to bring a new SMR online?
Considerably longer than grid interconnection alone, in most cases. Nuclear Regulatory Commission licensing for a new reactor design and site — even an SMR benefiting from more standardized components — commonly runs several years on top of the multi-year construction timeline itself. That's part of why most current hyperscaler nuclear commitments are structured as long-dated power purchase agreements or plant restarts (extending or reactivating existing licensed capacity) rather than pure greenfield SMR builds — the fastest path to nuclear megawatts right now is almost always an existing asset, not a new one.
What does the nuclear buildout mean for a typical power-adjacent land submission?
For most landowners, not much changes directly — the realistic power play for a standard parcel remains grid interconnection, or in some markets behind-the-meter gas generation, not nuclear. Where it matters indirectly is at the utility level: utilities investing in nuclear capacity (refueling existing plants, extending fuel cycles, or partnering on SMR programs) are signaling they're building ahead of large-load demand rather than just queuing it, which is a genuinely positive signal for grid-connected sites in that utility's territory even though the nuclear megawatts themselves aren't going to your specific parcel.
