Analysis
The Department of Energy has closed a $1.9 billion loan to NextEra Energy to help restart the Duane Arnold Energy Center, a nuclear plant in Palo, Iowa that has sat shut down since 2020, TechCrunch reported on September 8. Google is the plant's anchor customer, having signed a 25-year agreement last October to buy the power once it's back online.
Duane Arnold, a 601-megawatt boiling water reactor, began commercial operation in 1975. NextEra retired it in October 2020 after a derecho storm damaged its cooling towers and made continued operation uneconomical at the time -- a decision the company is now reversing as AI data-center demand has reshaped the math on keeping old reactors alive. NextEra, headquartered in Juno Beach, Florida and led by CEO John Ketchum, is already the largest electric power and energy infrastructure company in North America through its Florida Power & Light utility. NextEra and Google announced their restart partnership in October 2025; the DOE loan is the financing piece that makes it work, and Deputy Energy Secretary James Danly said the project will help "drive down electricity costs" once it's running.
A financing pattern, not an outlier
This is the second loan of its kind from the Department of Energy, and Google is not the only hyperscaler buying its way into restarted or extended nuclear capacity:
- Google / NextEra -- $1.9B DOE loan to restart Duane Arnold in Iowa, targeting Q1 2029, backed by a 25-year power purchase agreement.
- Microsoft / Constellation Energy -- an earlier deal to restart Three Mile Island Unit 1 (rebranded the Crane Clean Energy Center), backed by a prior $1B DOE loan.
- Amazon / Talen Energy -- a nuclear-powered data center campus tied to the Susquehanna plant in Pennsylvania.
- Meta / Constellation -- a long-term agreement tied to the Clinton Clean Energy Center in Illinois.
Each deal follows the same shape: an aging or shuttered reactor, a hyperscaler underwriting demand with a decades-long contract, and federal financing filling the gap between construction cost and near-term returns.
NextEra and Iowa officials project the restart will create roughly 400 direct, full-time jobs and generate more than $9 billion in economic activity for the state. The restart itself is expected to cost more than $1.6 billion, separate from the DOE loan, which finances the work rather than replacing it.
The announcement is a financing milestone, not a power milestone. Duane Arnold isn't expected to deliver a single megawatt until the first quarter of 2029, more than three years from now, on a reactor that utilities have historically struggled to bring back on time or budget. It's also a federal loan, not a grant: taxpayers now carry downside risk on a plant that was retired once already when the economics didn't work, on the bet that AI-era electricity demand keeps the math favorable through the end of the decade.
Google's AI data centers, in the meantime, are still running primarily on natural gas and the existing grid, the same as every other hyperscaler racing to add capacity faster than new generation, nuclear or otherwise, can be built.
