NextEra Energy (NEE) said in a press release on Sept. 8, 2026, that it had closed a loan with the U.S. Department of Energy (DOE), enabling a restart of the Duane Arnold plant targeted no later than the first quarter of 2029. The project is backed by a long-duration power purchase agreement (PPA) with Google (GOOG, GOOGL).
DOE Loan Supports Duane Arnold Restart
NextEra reached a combined conditional commitment and financial close with the DOE on a loan to support the Duane Arnold Energy Center’s restart, refurbishment, and construction. The financing, provided through DOE’s Office of Energy Dominance Financing, will fund the work needed to return the plant to service and supply reliable, around-the-clock baseload nuclear generation to the regional grid. The company said the loan “moves the company closer to restoring Iowa’s only nuclear plant and adding reliable, around-the-clock energy to the regional grid.”
Restart Timeline, Offtake, and Economic Impact
NextEra announced plans to restart Duane Arnold in October 2025, when Alphabet’s Google signed a 25-year PPA to purchase the majority of the plant’s output. Google intends to use the nuclear power primarily to support AI data centers and advance its 24/7 carbon-free energy goal. A local non-profit cooperative is expected to buy the remainder under similar terms.
The plant, located in Linn County near Palo and Cedar Rapids, Iowa, began operations in the 1970s and shut down in 2020 after more than four decades. Its operating capacity is about 615 megawatts, enough to power nearly 500,000 homes. The restart remains in planning and early engineering and inspection phases. The Iowa Utilities Commission issued a certificate authorizing construction and operation in June 2026. The U.S. Nuclear Regulatory Commission (NRC) must complete licensing approvals before the plant can resume operations. NextEra said other federal, state, and local agencies will oversee the work.
An economic study cited by NextEra projects more than $9 billion in economic benefits to Iowa over 25 years. The company estimates nearly 1,500 construction-phase jobs and about 400 to 450 permanent operating positions tied to the restart, along with roughly $75 million in tax revenue over the project’s life.
Federal and company statements present the financing as part of a broader effort to revive U.S. nuclear capacity, support non-emitting baseload power, and meet rising electricity demand from data centers and other customers. The DOE has indicated plans to restart multiple mothballed plants, with Duane Arnold among the early examples.
