Constellation Lands Up to $5B Conditional DOE Loan for Nuclear Uprates

Constellation announced on 27 de outubro de 2026, a conditional loan commitment of up to $5 billion from the U.S. Department of Energy’s Office of Energy Dominance Financing to support nuclear uprates across select Constellation facilities. According to the company’s announcement, issued from Baltimore, the potential funding would help accelerate projects that produce more around-the-clock power from existing nuclear plants to help meet growing energy demand.
The conditional commitment is subject to the completion of due diligence, the negotiation of definitive financing documents, and the satisfaction of applicable conditions. Constellation stated that the commitment does not, by itself, represent a final company decision to proceed with any individual uprate or at every facility under consideration. If the financing is finalized, the company said it will continue working with DOE, customers, regulators, and local stakeholders to advance individual projects.
Facilities Identified for Potential Uprates
The conditional loan commitment would be available to support potential uprates at the following facilities:
- Braidwood Clean Energy Center, Illinois
- Byron Clean Energy Center, Illinois
- Clinton Clean Energy Center, Illinois
- Dresden Clean Energy Center, Illinois
- LaSalle Clean Energy Center, Illinois
- Quad Cities Clean Energy Center, Illinois
- Calvert Cliffs Clean Energy Center, Maryland
- Limerick Clean Energy Center, Pennsylvania
Constellation said the commitment could lower financing costs and help the company deliver additional nuclear capacity at greater scale. The company describes uprates, which increase electricity production from existing plants, as one of the fastest and most cost-effective ways to add dependable power without building entirely new generation facilities or transmission corridors.
The DOE commitment builds on billions of dollars in private-sector investment already supporting Constellation’s efforts to increase nuclear output, the company said. According to Constellation, recent 20-year agreements with Google and Amazon have incentivized the company to invest more than $7 billion to add approximately 1,080 megawatts of nuclear capacity, and an agreement with Meta announced in 2025 supports a 30-megawatt expansion at the Clinton Clean Energy Center in Illinois. Constellation said those agreements demonstrate how large energy users can help enable new, reliable generation that flows to the regional grid and benefits all customers.
“This is how America wins the race for energy abundance – by pairing private-sector demand and investment with smart federal financing to unlock more power from the nuclear plants we already have,” said Joe Dominguez, Constellation chairman, president and CEO. Dominguez said the conditional loan commitment can help the company move faster and go further, putting more reliable power on the grid, creating and preserving good-paying jobs, strengthening American energy security, and helping families and businesses manage energy costs.
“The Energy Department is accelerating President Trump’s American nuclear renaissance and unlocking the full potential of our nation’s nuclear fleet,” said U.S. Secretary of Energy Chris Wright. Wright described uprates that maximize power generation from existing nuclear facilities as an example of the commonsense energy addition policies he said the Trump Administration is embracing.
Constellation said the potential investment advances the federal government’s effort to restore American nuclear leadership and reflects the goal of DOE’s UPRISE program of bringing the public and private sectors together to maximize electricity production from America’s existing nuclear fleet.
The Federal Programs Behind the Financing
The Department of Energy’s Office of Nuclear Energy announced the launch of UPRISE, the Utility Power Reactor Incremental Scaling Effort, on 12 de março de 2026. According to the department, the initiative is guided by executive orders that emphasize the strategic importance of nuclear energy for national security, economic growth, and energy dominance. UPRISE aims to enhance nuclear energy production by increasing the power output of existing reactors, bringing dormant facilities back online, completing stalled projects, and advancing new reactor construction. Its stated focus areas include uprates, license renewals, advanced fuel technologies, and strategic financing partnerships, with the department saying the effort is intended to significantly expand the nation’s nuclear energy capacity over the coming decades.
The Loan Programs Office operates as the Office of Energy Dominance Financing and performs the duties assigned to it through the Energy Policy Act of 2005, as amended, according to the department. Its Energy Dominance Financing Program, designated Section 1706, guarantees loans to projects that add energy to the grid or enhance reliability, including projects that enable operating infrastructure to increase capacity and output. The office states that it applies standard application processes to determine each project’s eligibility, readiness to proceed, and reasonable prospect of repayment, and that its subsequent due diligence phase is similar to that of commercial lenders, typically taking a minimum of six months to more than a year depending on the applicant’s level of preparation and project complexity. Gregory A. Beard serves as director of the office, according to the department.
