DOE Lends Constellation $5 Billion to Expand Nuclear Plants

The Department of Energy is lending Constellation Energy $5 billion to expand nuclear generating capacity at eight power plants, and most of the new electricity is already spoken for by the companies building the country's AI data centers, according to TechCrunch.

The loan, announced Tuesday and not yet finalized, is meant to help Constellation "uprate" 11 existing reactors across the eight plants, adding a combined 1.1 gigawatts of capacity, TechCrunch reported. Uprating is an industry term for expanding a reactor's output, typically by switching to more highly enriched uranium and upgrading plant equipment to handle the added power.

What are the loans actually for?

Constellation has already committed more than $7 billion of its own money to add 1,080 megawatts of nuclear capacity for Google, Amazon and Meta, according to the company's press release cited by TechCrunch. The federal loan would sit alongside that private spending.

The financing "could lower financing costs" for the projects, Constellation said in its press release.

Which plants are getting upgraded?

The eight facilities include six in Illinois — Braidwood, Byron, Clinton, Dresden, La Salle and Quad Cities — plus Calvert Cliffs in Maryland and Limerick in Pennsylvania, TechCrunch reported.

Who is buying the extra power?

Google has confirmed it will buy additional power from the Limerick plant in Pennsylvania and four of the Illinois plants, according to TechCrunch. Amazon is buying electricity from Calvert Cliffs in Maryland, and Meta is effectively purchasing the entire output of the Clinton plant in Illinois. TechCrunch reported that most or all of the new capacity at seven of the eight plants has already been sold to Google, Meta or Amazon.

Will the loan lower electricity bills for residential customers?

The Department of Energy described the loan as supporting "affordable, reliable power to American homes and businesses," TechCrunch reported. But the outlet found no evidence the new nuclear capacity will lower prices for residential ratepayers, and Constellation's own announcement does not address whether the projects will hold down or reduce electricity rates. TechCrunch reported that Constellation would not confirm the government's affordability claim when asked directly.

Why are tech companies buying so much nuclear power?

Google, Amazon and Meta have been competing for additional grid capacity to run power-hungry AI data centers, according to TechCrunch, and the companies are committing tens of billions of dollars over the coming years to lock in supply. TechCrunch noted that because power has become a competitive advantage among hyperscalers, those spending figures are likely understated. By reducing Constellation's cost of capital for the reactor upgrades, the federal loan could boost the company's profits, the buying companies' bottom lines, or both, TechCrunch reported.
