Google Secures $1.9B Federal Loan to Revive Iowa Nuclear Plant for AI Power

TL;DR

• The U.S. Department of Energy has offered a $1.9 billion loan through its Loan Programs Office to NextEra Energy to restart the shuttered 622-megawatt Duane Arnold nuclear plant in Palo, Iowa.
• Google will anchor the revival with a long-term power purchase agreement to buy the plant's carbon-free electricity to power its Midwest AI data centers, including its Council Bluffs campus.
• The project targets a restart by late 2028 or 2029, making Duane Arnold the third major U.S. nuclear restart and a key test of Big Tech's strategy to use nuclear to meet surging AI energy demand.

A Second Life For Duane Arnold

Six years after it went dark, Iowa's only nuclear power plant is coming back.

The Duane Arnold Energy Center in Palo, Iowa, shut down in August 2020 after 45 years of operation. Owner NextEra Energy Resources had planned to run it until 2034, but closed it early after storm damage and the loss of its main customer. Its 622 megawatts of carbon-free power were replaced largely by natural gas, wind, and solar.

Now, NextEra plans to bring it back. The revival is anchored by Google, which has agreed to buy the plant's full output under a long-term clean energy deal to power its expanding fleet of AI data centers in the Midwest. The U.S. Energy Department is backing the effort with a $1.9 billion conditional commitment to NextEra through its Loan Programs Office.

If approved and completed on schedule, Duane Arnold would return to the grid in late 2028 or early 2029, just in time for the next wave of AI compute growth.

Breaking Down The $1.9 Billion Federal Loan

The $1.9 billion in federal support comes as a loan guarantee from the Energy Department's Loan Programs Office, the same financing arm that backed the $1.5 billion Palisades restart in Michigan and the $1.1 billion Three Mile Island restart in Pennsylvania.

According to NextEra and DOE officials, the loan will cover the bulk of the restart costs, including major equipment refurbishment, steam turbine and cooling tower upgrades, new fuel procurement, workforce rehiring and training, and licensing work with the U.S. Nuclear Regulatory Commission.

Unlike a grant, the loan must be repaid with interest from future electricity revenues - primarily from Google's purchase agreement. The conditional commitment still requires final due diligence, environmental review, and NRC approval to transfer the plant back to operating status. NextEra has already filed to relicense the site and has begun initial inspections.

Energy Secretary officials framed the loan as part of a broader push to triple U.S. nuclear capacity by 2050 and keep AI infrastructure on American soil. Federal backing significantly lowers the financing risk for what would otherwise be a complex, capital-intensive restart.

Inside Google's Power Purchase Deal

For Google, the deal is about 24/7 clean power for AI.

Google has committed to purchase the carbon-free electricity from Duane Arnold for 20-plus years under a structured power purchase agreement with NextEra. While the companies have not disclosed the exact price per megawatt-hour, the agreement is designed to give NextEra revenue certainty to secure the federal loan while giving Google firm, round-the-clock power that wind and solar alone cannot provide.

The power will help feed Google's massive data center footprint in Iowa, including its Council Bluffs campus - one of the company's largest in the U.S. - as well as future AI-optimized facilities in the region. Google said the nuclear power will count toward its goal of running all of its operations on 24/7 carbon-free energy by 2030, a target that has been strained by AI-driven electricity growth.

Google is also expected to provide technical and workforce support for the restart timeline, a model similar to Microsoft's deal to back the Three Mile Island restart with Constellation and Amazon's nuclear deals with Talen Energy and X-energy. Google executives have said nuclear is essential because AI data centers need uninterrupted baseload power that does not depend on weather.

Why Big Tech Is Betting Big On Nuclear

Duane Arnold is not an isolated bet. It is part of a sweeping shift in how Big Tech powers AI.

U.S. data center electricity demand is projected to more than double by 2030, driven almost entirely by AI training and inference. Utilities in Iowa, Virginia, Texas, and the Midwest have warned of looming capacity shortfalls. After years of focusing on wind and solar PPAs, Google, Microsoft, Amazon, and Meta have all pivoted to nuclear in the last 18 months.

Restarting a shuttered plant is faster and cheaper than building a new reactor. Duane Arnold already has grid interconnection, water rights, a trained community, and NRC site approval - assets that would take a decade to replicate for a new build. Industry analysts estimate a restart costs $1.5 billion to $2.5 billion, versus $10 billion-plus for a new large reactor.

The Duane Arnold deal follows the successful restart playbook set by Palisades in Michigan and Unit 1 at Three Mile Island, both now tied to Big Tech buyers. NextEra CEO John Ketchum has called U.S. nuclear restarts a golden opportunity, noting the company is also evaluating a restart of additional units and development of new small modular reactors for Google and other hyperscalers.

What It Means For Iowa And U.S. Nuclear Power

For Palo and Linn County, the restart means jobs and tax revenue. NextEra says the project will create up to 1,000 construction and refurbishment jobs and restore more than 500 permanent high-paying operations jobs lost in 2020. Local leaders, who fought the original closure, have largely welcomed the news, though some environmental groups have raised questions about waste storage, water use from the Cedar River, and cost risks to taxpayers if the project stalls.

For the U.S. nuclear industry, Duane Arnold is a critical momentum test. If successful, the U.S. will have brought three shuttered reactors back to life in under five years, proving that restarts can be a scalable bridge to new construction. The NRC is now juggling restart reviews for Palisades, Three Mile Island, Duane Arnold, and potential new applications, stretching agency staffing.

Challenges remain. NextEra must still secure final NRC restart authorization, complete major maintenance deferred since 2020, secure new uranium fuel contracts in a tight market, and navigate potential legal challenges. The DOE loan is conditional, not final.

But with Google's balance sheet behind it and federal financing in place, Duane Arnold has gone from long shot to likely. For Big Tech and the nuclear industry alike, Iowa is now ground zero for the AI energy race.
