DOE Approves $1.9 B Loan to Restart Iowa’s Duane Arnold Nuclear Plant
9/9/2026, 5:35:18 PM
Core Event
On September 8, 2026, the U.S. Department of Energy closed a loan of up to $1.9 billion to help NextEra Energy revive the Duane Arnold Energy Center in Linn County, Iowa. The loan will fund refurbishment of the 45-year-old, 615-MW reactor, with operations targeted for early 2029 pending NRC licensing. Google has signed a 25-year power-purchase agreement for the plant’s output.
Background & Context
The plant shut in 2020 after storm damage to its cooling towers and low natural-gas prices made it uneconomical. Rising demand from AI data centers has renewed interest in dormant reactors as clean, firm power sources. The DOE has similarly financed restarts at Three Mile Island (US$1 billion) and Palisades, Michigan (US$1.5 billion).
Data & Statistics
- Loan amount: up to $1.9 billion.
- Capacity: 615 MW, enough for ?500,000 homes.
- Construction jobs: ?1,500 temporary positions.
- Operational jobs: >450 permanent roles.
- Economic impact: study estimates >$9 billion regional benefits over 25 years and ?$75 million in tax revenue.
- Power allocation: 50 MW for a local cooperative, covering 18 % of Iowa’s demand growth since 2021.
Official Statements & Responses
Deputy Secretary of Energy James P. Danly said the plant’s return will “drive down electricity costs” while supporting jobs. Google’s agreement secures relatively clean power for its AI workloads.
Timeline
- 2020: Plant shut after storm damage.
- 2024-2025: DOE extended loans to other dormant reactors.
- September 8 2026: DOE finalizes $1.9 billion loan to NextEra.
- Early 2029: Planned restart, contingent on NRC approval.
Verbatim Quotes
- “Returning 615 megawatts of reliable baseload generation will drive down electricity costs, while supporting thousands of American jobs,” — U.S. Deputy Secretary of Energy
- “Duane Arnold is exactly the kind of investment that will help restore American nuclear leadership, strengthen our energy security, and deliver the affordable, reliable power Americans need to fuel our nation’s future,” — Greg Beard, Energy Department loan office
Why It Matters
Reviving Duane Arnold adds low-carbon baseload capacity for AI data centers and demonstrates federal willingness to finance nuclear refurbishment, offering a model for other mothballed reactors. The long-term corporate power-purchase agreement highlights a growing partnership between the tech sector and legacy energy infrastructure.
