The U.S. Department of Energy provides $17.5 billion in loan guarantees to five nuclear power projects to accelerate the construction of nuclear reactors.

The U.S. government is using large-scale policy financing as leverage to push nuclear power construction back on track.

On June 23, the Department of Energy announced that it would provide a total of $17.5 billion in conditional loan guarantees to nuclear equipment manufacturer Westinghouse Electric and a group of unnamed U.S. utility companies, for the procurement of long-cycle critical components for ten AP1000 nuclear reactors, covering five sites. The Department of Energy stated that the purpose is to kick-start component ordering as soon as possible, thereby advancing the deployment timeline of the related nuclear power units by two to three years.

Energy Secretary Chris Wright said that these loans are not issued directly to Westinghouse Electric, but are used to activate the supply chain to speed up reactor construction, and projects will be distributed across several locations in the U.S. He also revealed the projects will secure power purchase agreements of up to 25 years signed by ultra-large data center operators, with prices sufficient to support project progress without raising local electricity rates.

Loan Structure: Both Parties Must Contribute $500 Million to Unlock

According to Julie Kozeracki, Acting Chief Investment Officer at the Department of Energy's Loan Program Office, the loans use a Special Purpose Entity (SPE) structure. Each loan corresponds to a group of equipment for two AP1000 reactors, with Westinghouse Electric and a utility company both involved. The loans can only be "unlocked" and activated once both parties have committed $500 million in equity.

Long-cycle components include large reactor pressure vessels, steam generators, and prefabricated structural modules, all of which require years to manufacture. Greg Beard, head of the Department of Energy's Energy-Dominated Financing Office, said the department will complete the matching of five SPEs and utility partners before the end of this year, with selection focusing on which partners are most likely to drive fast, efficient construction.

Seven utility companies or energy enterprises have already signed letters of intent and each confirmed their site, but the final five to receive component allocations have not yet been determined. Kozeracki said that the loan structure allows the Department of Energy to flexibly adjust component allocation during project development to handle situations where partners "change direction."

Timeline: Earliest Grid Connection in Mid-2030s

Beard said that the first batch of reactors could begin construction in about five years, and power supply from the entire project is expected by the mid-2030s.

This loan guarantee operates independently yet complementarily with another financing arrangement previously reached by the U.S. Department of Commerce. Previously, the U.S. government, through the Department of Commerce, reached an agreement with Westinghouse Electric's owners—Canadian uranium producer Cameco and Brookfield Asset Management affiliates—pledging $80 billion in financing support for the construction of ten nuclear power units.

Beard characterized the long-cycle loans as "independent, parallel, and complementary" to the Commerce Department's arrangement above.

Standardized Design: Lower Costs, Restart Nuclear Power Construction

This round of Department of Energy financing support focuses solely on the AP1000 reactor type, based on a clear cost logic. Beard stated that standardized single-reactor design helps lower capital costs for nuclear power, "We believe these projects are economically viable for utility shareholders, electricity users, and ultra-large data center operators."

Chris Wright admitted that the U.S. nuclear power industry has "been nearly stagnant for decades." The latest nuclear power units constructed in the U.S. both used the AP1000 design at Georgia Power’s Vogtle plant, but faced planning mistakes, supply chain issues, and challenges from the COVID-19 pandemic. He stated that despite this, the AP1000 design itself is "robust and reliable," and is worth duplicating and promoting.

Rapid growth in power demand from data center operators is a key driver of this round of nuclear revival. Wright said ultra-large data center operators are expected to sign long-term power purchase agreements in advance, providing financial stability for the projects, and some may even take equity stakes in the nuclear projects. In addition, actual construction will choose engineering, procurement, and construction (EPC) contractors through competitive tender bidding.
