DOE lines up $17.5bn for 10 US nuclear units

The U.S. Department of Energy’s Office of Energy Dominance Financing has approved a conditional commitment for up to $17.5 billion in American Nuclear Supply Chain Loans. The package is intended to provide the majority of financing needed for Westinghouse Electric Company to purchase long‑lead time items for up to 10 AP1000 nuclear reactors in the United States. These components typically take years to manufacture and deliver, and securing them is described as critical to project schedules.

The loan package is structured as up to five separate loans, with each loan supporting two reactors at a given project site. This framework is designed to back multiple large reactor deployments while tailoring financing to individual project partnerships and locations.

Under the contemplated structure, Westinghouse will partner with up to five eligible utilities and energy companies. For each two‑reactor project, Westinghouse and the partner utility are expected to jointly own the project. Long‑lead items for each project will be procured at a fixed price, aiming to provide greater cost predictability during early stages of development.

Before being able to access DOE loan funds, both Westinghouse and each utility or energy company partner must fully commit project equity of approximately $500 million each, or about $1 billion in total per two‑reactor project. This equity requirement places a significant share of upfront financial responsibility on the project owners before federal financing is drawn.

Each AP1000 unit is cited as producing about 1.1 gigawatts of electricity. In aggregate, the ten planned reactors would provide roughly 11 gigawatts of capacity, described as enough to power nearly 10 million American households. DOE and Brookfield materials indicate a goal of having all 10 units under construction by 2030.

Westinghouse has signed letters of intent with seven potential partners, each with identified project sites. Although candidate locations have been identified, DOE officials have declined to disclose specific sites, keeping geographic details of the program confidential at this stage.

The DOE loans remain conditional and are not yet finalized. Disbursement of funds will depend on satisfying a series of technical, legal, environmental, and financial conditions, as well as on the negotiation and execution of definitive financing agreements. Only once these requirements are met will the conditional commitments convert into actual loan disbursements.

DOE materials state that by covering complex, long‑lead components, the financing could accelerate construction and commercial operation of the reactors by up to three years. By securing supply chain items earlier and at scale, the program is intended to shorten development timelines and support a coordinated buildout of large nuclear capacity across multiple U.S. sites.
