Iowa’s Closed Nuclear Plant Gets a $1.9 Billion Federal Loan

The Energy Department closed a loan of up to $1.9 billion on September 8 to help NextEra Energy restart Iowa’s only nuclear plant. Google will buy most of the power for 25 years. Iowa is being promised jobs, tax receipts, and a pledge that households will not pay to bring the reactor back.

The 615-megawatt Duane Arnold Energy Center in Palo has been dark since a 2020 storm, and no shuttered U.S. nuclear plant has resumed operations. The loan funds a rebuild aimed at the first quarter of 2029. The megawatts, if they return, are largely spoken for.

The $1.9 Billion Title 17 Loan

The Department of Energy’s Office of Energy Dominance Financing closed a loan of up to $1.9 billion to NextEra, a combined conditional commitment and financial close. The credit sits in the Title 17 Energy Financing Program and is the third federal restart loan for a closed U.S. reactor, after Palisades in Michigan and the Crane Clean Energy Center in Pennsylvania.

DOE said the 615 megawatts would be enough to power nearly 500,000 homes and would feed the Midcontinent Independent System Operator grid. It put construction and refurbishment work at about 1,500 jobs and permanent operations at 462 jobs. Deputy Secretary James P. Danly tied the close to a May 2025 executive order, Reinvigorating the Nuclear Industrial Base, and to a claim about bills that the offtake contract makes harder to cash.

Returning 615 megawatts of reliable baseload generation will drive down electricity costs, while supporting thousands of American jobs.

EDF Director Gregory A. Beard called Duane Arnold the kind of investment that restores nuclear capacity and delivers affordable power. NextEra Energy Resources President and CEO Brian Bolster would not give reporters a full restart price, but said the work runs to multiple billions of dollars, which means the federal loan is a large piece of a larger bill, not the whole bill.

Danly toured the Palo site the day the loan closed. The department posted the visit as proof that Iowa’s plant is coming back, and that the output will cut costs for Iowans.

That cost claim is the fight inside the deal. The plant returns as capacity on MISO. The paying customer for most of the output is not an Iowa household.

Google Is Buying Most of the Output

On October 27, 2025, Google and NextEra announced a collaboration that includes restarting Duane Arnold. Google said it expects the plant back online in early 2029, with more than 600 megawatts of always-on nuclear energy heading to the regional grid to support its cloud and AI infrastructure in Iowa. In the same post, the company said it is enabling the restart investment and covering costs for the production of energy from the plant.

Restarting a once fully operational plant is the fastest path to unlock large-scale nuclear power to meet AI growth in the near-term.

NextEra described a 25-year power purchase agreement under which Google takes the majority of the output. Central Iowa Power Cooperative will buy the remaining share on the same contract terms. NextEra has also signed agreements to acquire CIPCO and Corn Belt Power Cooperative’s combined 30 percent interest, which would leave NextEra as sole owner.

The physics still run through the public grid. A nuclear unit of this size does not island itself for one tenant. What the PPA changes is who pays for the rebuild and who books the carbon-free megawatt-hours. Google gets a 25-year strip of firm power for Iowa computing load. CIPCO keeps a slice on Google’s terms. Everyone else is asked to treat the restart as a reliability gift and a jobs program.

NextEra chairman, president, and CEO John Ketchum has said new generation for new demand can keep power affordable for existing customers, and that Iowa families and businesses should not be asked to bear the costs of grid growth. Google’s language about covering production costs is the private-side version of that pledge. The federal loan is the public-side version.

Why the Plant Went Dark in 2020

Duane Arnold did not fail as a machine first. It failed as a contract. NextEra and Alliant Energy agreed in 2018 to cut short a power purchase deal that had been set to run to 2025, five years early. Alliant paid $110 million and took 340 megawatts from repowered NextEra wind farms in Iowa. Alliant said at the time that dropping the nuclear contract would save its customers $300 million. The Nuclear Regulatory Commission license ran to February 21, 2034, so the unit was being retired with 14 years of licensed life still on paper.

Iowa already ran on cheap wind, and a baseload plant that cannot ramp with the breeze was easy to strand. NextEra had even told investors the plant’s contribution to earnings was negligible. The August 2020 derecho turned an orderly retirement into a wreck.

HOW THE LIGHTS WENT OUT

1. July 2018: NextEra and Alliant cut the nuclear PPA by five years. Alliant pays $110 million and shifts to 340 MW of repowered wind.
2. August 10, 2020: A derecho damages the cooling towers, cuts off-site power, and scrams the reactor. NextEra judges repairs pointless before the planned October 30 close.
3. October 12, 2020: NextEra certifies that all fuel is out of the reactor. The plant enters SAFSTOR, with full decommissioning then slated for 2075.
4. End of April 2022: All spent fuel sits in dry casks at the on-site storage pad.
5. Early 2025: NextEra tells the NRC it wants to restore operations. An exemption request lands on January 23.
6. October 27, 2025: Google signs the 25-year offtake that makes a multi-billion-dollar restart bankable.
7. June 2026: The Iowa Utilities Commission issues a certificate authorizing construction and operation.
8. September 8, 2026: DOE closes the $1.9 billion loan.

The cooling towers were non-safety gear, but they were the heat sink the plant needed, and the calendar made replacement irrational. Six years later, the same company is borrowing from the United States to rebuild what it would not fix in 2020, because a hyperscaler will pay for firm power that wind still cannot guarantee at 3 a.m.

A Defueled Core and a 2034 License

The NRC records that Duane Arnold permanently ceased operations on August 10, 2020 after more than 45 years. It is a General Electric Type 4 boiling-water reactor, licensed at 1,912 megawatts thermal, with Mark I wet containment, sitting eight miles northwest of Cedar Rapids. The operating license was issued on February 22, 1974, renewed on December 16, 2010, and still expires on February 21, 2034.

That last date is the quiet problem inside a 25-year PPA. A restart in the first quarter of 2029 would leave about five years of remaining license term unless the NRC later extends it. Google’s contract, if it runs from 2029, would reach to 2054. The loan can close. The offtake can be signed. The core is still empty, and the clock on the current license is short.

NRC FILINGS ON THE DESK

• The exemption: NextEra asked on January 23, 2025, for relief from termination rules in 10 CFR 50.82 so a plant that certified shutdown can be authorized to run again.
• The operating license: A November 20, 2025, request would revise the license and technical specifications for resumed power operations.
• The security plan: An update to support restart was submitted on December 17, 2025, and supplemented on February 11, 2026.
• The emergency plan: A January 30, 2026, request would reinstate emergency preparedness for an operating site.

The NRC has stood up a Duane Arnold Restart Panel to coordinate licensing, inspection, and oversight. Staff still have to restore an operational licensing basis, verify that components can run safely, and finish a NEPA review of the environmental effects of turning a SAFSTOR site back into a generating station. Iowa’s utilities certificate in June cleared a state gate. It did not reload the fuel.

Palisades Loads Fuel While Iowa Waits

Duane Arnold is the slowest of the three federally financed restarts, and it has the largest loan. Palisades, closed in May 2022, is already loading fuel. Holtec International, which is reviving the 800-megawatt Michigan plant after a $1.52 billion DOE loan, began putting assemblies back in the core in early September 2026. Holtec Chief Nuclear Officer Fadi Diya called fuel load a milestone and said the remaining work is about disciplined execution. Holtec has pointed to 2027 for a return to service.

Constellation Energy is rebuilding Unit 1 at Three Mile Island as the Crane Clean Energy Center, an 835-megawatt machine with a 20-year Microsoft offtake and a $1 billion DOE loan, aimed at late 2027. FERC in June 2026 let Constellation shift interconnection rights from a retiring fossil plant to Crane, a workaround for a transmission queue that could have added years.

THREE CLOSED PLANTS, THREE FEDERAL LOANS

No closed U.S. reactor has generated again. Palisades is closest. Crane has a tech offtaker and a 2027 date. Duane Arnold has the fattest federal check and the longest wait, which is what a 2020 derecho and a full defuel cost when the rebuild includes cooling towers, a restored emergency plan, and a core that has been empty since October 2020.

Who Pays If the Restart Slips?

If the NRC says no, or says later, the offtake does not ship and the construction payroll does not last. Title 17 is a loan, not a grant, so NextEra is on the hook first. The hidden book is the federal credit. A multi-billion-dollar restart that misses 2029 still spent a lot of someone else’s patience, and the Office of Energy Dominance Financing has now stacked three of these bets.

Beyond Nuclear has asked an Iowa court to review the utilities commission’s go-ahead after the commission rejected a July request to reconsider. The group argues the project will not help Iowa consumers, because Google is buying most of the power and can resell energy outside the state. DOE has not laid out, in public, how the loan sits against a pledge that households will not fund data-center growth.

WHAT WE KNOW

• The offtake: Google takes most of the 615 MW under a 25-year contract; CIPCO buys the rest on the same terms.
• The pledge: NextEra says existing Iowa customers will not bear the costs of the power Google buys.
• The credit: Up to $1.9 billion is a federal loan closed on September 8, 2026.

WHAT IS UNCONFIRMED

• Full rebuild cost: Bolster put it at multiple billions and would not publish a total.
• License past 2034: A 25-year PPA outlasts the current NRC expiration by about two decades.
• Bill relief: Danly said 615 MW will drive down electricity costs; no public model shows how much, or for whom, once Google’s share is stripped out.

On MISO, extra baseload can ease a tight hour for everyone. That is the honest version of the homes-equivalent line. It is not the same as 615 megawatts delivered to Cedar Rapids tap water heaters. The people with skin in the fuel cycle are Google’s Iowa compute load, NextEra’s shareholders, CIPCO’s remaining slice, Palo’s construction hall, and a federal loan officer.

1,500 Jobs, $9 Billion, and a Thin Slice of Power

Gov. Kim Reynolds signed state incentives for nuclear development, and the Iowa Utilities Commission’s June certificate was the local political win. A study by Strategic Economic Research, which Google has pointed to, estimates more than $9 billion in economic value for Iowa over 25 years, plus about $75 million in tax revenue. DOE’s own close sheet is more specific on payroll: about 1,500 jobs while the plant is rebuilt, then 462 high-paying operations jobs if it runs.

Those figures are the state’s dividend. They are real if the NRC restores the license and the cooling towers stand. They are also the substitute for the megawatts. In 2018, Alliant paid to leave nuclear because wind was cheaper for Iowa retail customers. In 2026, the same site is a federal-and-Google project that sells Linn County a payroll and sells Mountain View a 25-year strip of firm power.

WHERE THE ARGUMENTS SPLIT

• Danly and Beard: Restarted nuclear cuts costs, adds jobs, and restores a plant that can run around the clock.
• Ketchum: New load should pay for new generation, so existing Iowa customers are not stuck with Google’s bill.
• Beyond Nuclear: Most of the output is contracted to Google, which can move power out of state, so the consumer case is thin.

Other closed Midwest units are already being named in the same breath, because a third federal restart loan makes the next one easier to imagine. Palisades still has to finish the first revival. Duane Arnold still has to put fuel back in a vessel that has been empty since 2020, under a license that, as written, dies in 2034.

The loan is closed. The offtake is signed. The core is empty, and the first restarted U.S. nuclear plant, if one actually returns, is more likely to be in Michigan than in Palo.
