The Uprate Rush: Existing Reactors Powering AI Right Now

Zach Martin

Welcome to Nuclear Capital on I R Hub, the KMKT I R Hub Radio exclusive. I'm Zach Martin, and today we're skipping the big nuclear renaissance overview and going straight to the uprate rush. Quick disclaimer first. Every company we discuss is for informational purposes only. None of this is investment advice or a recommendation to buy or sell any security.

And I'm Emily Martin. The story is simple to say and hard to price. Big tech wants firm power now, and the fastest megawatts are coming out of reactors that already exist. Constellation's recent contracts show it clearly.

Zach Martin

Start with Google. On October 6, Constellation announced a 20 year power purchase agreement supporting 890 megawatts of new capacity through uprates across 11 units in Illinois, Pennsylvania and New Jersey. First added capacity is expected in 2028. There's also a separate 15 year agreement for 2,700 megawatts from the existing PJM fleet.

Emily Martin

Then Amazon, on September 30. Calvert Cliffs in Maryland, 690 megawatts covered, including a planned 190 megawatt uprate expected between 2030 and 2032, and more than 3 billion dollars of infrastructure investment. It's also meant to give revenue certainty for relicensing the plant for another 20 years.

Zach Martin

Add Meta's 30 megawatt expansion at Clinton and Constellation says the hyperscaler agreements support more than 7 billion dollars of investment for about 1,080 megawatts. My view is that this is capital discipline in its cleanest form. You're upgrading turbines and equipment at licensed sites, not waiting a decade for a greenfield build.

Emily Martin

I agree on the direction, but let's be careful about the word clean. The Department of Energy's up to 5 billion dollar offer, announced October 27 under the UPRISE program, covers about 1.1 gigawatts across eight plants. It's a conditional commitment. Not a loan, not cash. Constellation still has to meet technical, legal, environmental and financial conditions and sign definitive documents.

Zach Martin

Fair enough, but you're not calling it weak, are you?

Emily Martin

No. I'm calling it unfinished. And the reporting notes the Google portfolio doesn't exactly match the eight plants in the federal package. Related, not identical. Investors should keep those lists separate.

Zach Martin

That's a good correction. Also worth saying, these deals flow through the regional PJM grid. Amazon said Calvert Cliffs output keeps flowing into the grid. It's not a dedicated wire to a data center. The companies say that protects ratepayers, though that's their position, not an independent savings estimate.

Emily Martin

Now the gap. Across the register we've been tracking, roughly 10.8 gigawatts is signed and binding, against more than 40 gigawatts that's only announced or non binding. That's the headline risk. Paper gigawatts versus firm electrons.

Zach Martin

Meta is the best contrast. It has signed with Vistra for existing plants plus uprates, and it has longer dated deals with Oklo and TerraPower. Those advanced designs run on 2030s timelines, with first of a kind engineering risk. I'd never call them worthless. I'd call them a different asset class on a different clock.

Emily Martin

I'd push on that. Long dated optionality is how new technology gets financed. If nobody signs early, nothing gets built.

Zach Martin

Agreed, but the market doesn't pay for optionality the same way it pays for megawatts arriving in 2028. And that's what we've seen. Nuclear stocks have sold off at times even after contracting wins. My read is that capital prefers near term megawatts from the operating fleet over distant advanced designs.

Emily Martin

That's an interpretation, and a reasonable one, but I'd hold it loosely. Selloffs can come from valuation or sentiment too. A contract win doesn't guarantee a rising share price.

Zach Martin

Granted. Now the fuel side, briefly. Cameco's third quarter call on November 4 stressed disciplined contracting. Management cited contract floors in the mid to high 70 dollars per pound and ceilings approaching 160, and said it would rather protect terms than chase volume at poor prices.

Emily Martin

And its CEO said AI demand is added growth potential, not the foundation of the strategy. That's a useful tone check for the whole sector. Patient contracts, executed carefully.

Zach Martin

So the watch list is financial close, approvals, equipment, and then actual megawatts online. Steady progress beats big headlines.

Emily Martin

One more reminder. Everything we've covered is informational only, not investment advice.
