Utilities Are Filing Their Own SMR Permits Now

For the last few years, small modular reactors have been a vendor's pitch: NuScale or BWXT explaining to utilities why SMRs would eventually matter. That pitch just changed hands. Read the Energy & Power and Data Centers filings from this cycle together, and the utilities themselves have started filing the permits, building the internal teams, and putting real numbers into their own guidance. The vendors are still the ones building the reactors. They've stopped being the ones setting the pace.

Utilities Started Filing Their Own Permits

AEP, Duke, NextEra, and WEC all initiated early site permits for small modular reactors this cycle — a filing a utility submits on its own behalf, to its own regulator, for its own future site. That's a different posture than fielding a vendor's proposal. NextEra stood up a dedicated internal SMR development organization and has already mapped 6 gigawatts of co-location opportunities at its existing nuclear sites:

"We have 6 gigawatts of SMR co-location opportunities at our nuclear sites, and we are working to develop new greenfield sites."

SMR has become something a utility plans around internally, the same way it plans a transmission line or a gas plant, rather than something a vendor has to convince it to try.

The Earnings Math Already Exists

What separates a real capital-planning shift from a talking point is whether it shows up in guidance. It does. NextEra quantified its nuclear recontracting down to the cent: Point Beach's 14% capacity extension adds $0.03 to annual EPS on its own, and full recontracting of the fleet at current market prices adds $0.21. Constellation is doing the same thing from the supply side — it's sitting on 147 million megawatt-hours of uncontracted nuclear generation and pricing it at a $0.30 to $1.00 premium above the federal production tax credit floor. Both numbers describe the same underlying asset getting repriced now that hyperscalers need decades of guaranteed baseload power.

BWXT's Backlog Just Flipped

BWXT has built naval reactors for the U.S. government for decades, and government work has always been the larger half of its business. This cycle, its commercial nuclear backlog grew 85% year-over-year and, for the first time in the company's history, is growing faster than its government backlog. Book-to-bill on the commercial side crossed 2x in a single quarter. The company that used to depend on Washington for its reactor demand is now watching the private sector pull harder.

The Companies Actually Building These Things Are Being Cautious

Here's where the story earns its skepticism. NuScale holds the only SMR design certified by the Nuclear Regulatory Commission — the single most concrete proof point the entire sector points to. This cycle, NuScale posted a negative revenue adjustment tied to a contract renegotiation with Fluor on its flagship Romania project. Management called it "not indicative of a trend," but a renegotiation on the industry's most advanced project is worth sitting with. NuScale also said it could look capacity-constrained "a couple of years into the future." BWXT used almost identical language about its own manufacturing capacity.

So the two companies with the clearest path to actually delivering an SMR are the ones signaling that the pipeline behind them is thinner than the pace utilities are now setting. Utilities are filing permits and writing EPS guidance around technology that its own builders are quietly flagging as supply-constrained.

None of this shows up by reading one company's filing. NuScale's renegotiation looks like a footnote on its own. NextEra's $0.21 EPS line looks like routine recontracting on its own. Read across utilities, reactor vendors, and component manufacturers in the same window, and it's a sector moving faster than its supply chain — with the clearest evidence of that gap coming from the two companies who'd know first.
