The Trump administration is handing Constellation Energy $5 billion in loans to expand nuclear generating capacity by 1.1 gigawatts across eight power plants. Most or all of the extra power from seven of those facilities has already been purchased by Google, Meta, or Amazon - because nothing says "affordable, reliable power to American homes and businesses" like a pre-sold electricity block for AI data centers.

Constellation plans to use the financing to "uprate" 11 existing reactors - an industry term for squeezing more capacity out of a reactor, often by using more highly enriched uranium and upgrading equipment to handle the increased power levels. The company says it had already committed to spending more than $7 billion to add 1,080 megawatts of nuclear capacity to deliver power to Google, Amazon, and Meta. The loan commitment, which has yet to be finalized, "could lower financing costs" for the projects, Constellation said in a press release - a phrase that is doing a lot of heavy lifting in a sentence about $5 billion in government money.

The eight power plants include six in Illinois (Braidwood, Byron, Clinton, Dresden, La Salle, and Quad Cities), one in Maryland (Calvert Cliffs), and one in Pennsylvania (Limerick). Google is already the confirmed buyer of additional power from the Pennsylvania plant and four Illinois power plants, while Amazon is buying electricity from the Maryland plant and Meta is effectively buying the entire Clinton power plant in Illinois - because nothing says "diversified energy portfolio" like one company buying an entire nuclear plant's output.

On Tuesday, the Department of Energy touted the loan as supporting "affordable, reliable power to American homes and businesses," though there is no evidence that the new nuclear capacity will lower prices for residential ratepayers. Constellation's announcement does not say whether the projects will maintain or lower electricity rates, and the company would not confirm the government's claim to TechCrunch - presumably because "we're not sure either" is not a great press release quote.

Hyperscalers, including Google, Amazon, and Meta, have been scouring the grid for additional capacity to support their AI data centers. Tech companies are paying handsomely for energy, committing tens of billions of dollars over the coming years. Given that power has become a competitive advantage, that estimate is probably on the low end - because when has a tech company ever underestimated its own future energy needs?

By lowering the cost of capital for the upgrades, the Department of Energy's loans could boost Constellation's bottom line, that of the hyperscalers - or both. The only group not explicitly mentioned in the bottom-line-boosting calculus is the residential ratepayer, who will presumably continue to enjoy the affordable, reliable power of watching their electricity bill go up while a chatbot writes poems about it.
