DOE Offers Vistra $4.2B Loan for Ohio, Pennsylvania Nuclear Uprates

The US Department of Energy said Tuesday it has offered Vistra Corp a conditional loan commitment of up to $4.2 billion to fund uprates at three of the company’s nuclear plants in Ohio and Pennsylvania, the latest step in a federal push to squeeze more megawatts out of the existing US reactor fleet rather than wait years for new ones.

The financing, offered through the DOE’s Office of Energy Dominance Financing (EDF) — the renamed Loan Programs Office — would support planned capacity increases at Vistra’s Beaver Valley plant in Shippingport, Pennsylvania (1,872 MWe across two pressurized-water reactors), Davis-Besse in Oak Harbor, Ohio (908 MWe) and Perry in Perry, Ohio (1,268 MWe). Combined, the uprates are expected to add about 433 MW of new capacity across the three sites.

A conditional commitment, not a signed check

The $4.2 billion figure is a conditional loan commitment, meaning Vistra must still satisfy technical, legal, environmental and financial conditions before DOE enters into definitive financing documents and actually disburses the money. The agreement also includes an option to extend financing to a potential future uprate at Vistra’s Comanche Peak plant in Texas, though no commitment has been made for that site.

“President Trump and Secretary Wright have set a clear direction for America’s nuclear future, and EDF is financing the projects that advance that mission,” Gregory Beard, director of the DOE’s Office of Energy Dominance Financing, said in a statement announcing the offer.

The Meta link

The uprates trace back to a commitment Vistra made in January, when the company said it had signed 20-year power purchase agreements with Meta covering a total of 2,609 MW of carbon-free capacity from its PJM nuclear plants — including energy and capacity from the planned uprates at Perry, Davis-Besse and Beaver Valley. Vistra and Meta described it at the time as the largest nuclear uprate commitment ever backed by a single corporate customer. Tuesday’s DOE announcement does not detail Meta’s financial role in the newly financed work, but it effectively provides the federal financing needed to execute the uprate portion of that deal.

Part of a broader federal uprate push

The Vistra loan falls under DOE’s Utility Power Reactor Incremental Scaling Effort, a financing program aimed at adding 2.5 GW of nuclear capacity through uprates and restarts by 2027 and 5 GW by 2029, as part of a longer-term goal of roughly quadrupling US nuclear capacity to 400 GW by 2050. The office has also backed restart projects at plants like Palisades in Michigan and the former Three Mile Island site in Pennsylvania, now known as the Crane Clean Energy Center.

The announcement landed the same day Google and Constellation Energy said they had signed a separate 20-year agreement to fund 890 MW of nuclear uprates across 11 Constellation units in the PJM grid, a deal unrelated to Vistra’s but driven by the same underlying pressure: AI data centers are adding load to PJM faster than new generation can be built, and both federal financing and corporate power contracts are being funneled into upgrading reactors that already exist. Amazon struck a similar uprate-linked nuclear deal with Constellation at Calvert Cliffs in late September, and the Nuclear Regulatory Commission completed its environmental review for the Three Mile Island Unit 1 restart last month.

Timeline still uncertain

DOE and Vistra have not published a plant-by-plant schedule for when the 433 MW of additional capacity would come online. The companies have previously indicated the work would be phased in over several years as each unit’s uprate is engineered, licensed and installed during planned outages, a process that typically takes multiple refueling cycles per reactor.
