The United States Department of Energy (DOE) has closed a loan of up to $1.9bn to NextEra Energy to support the restart of the Duane Arnold nuclear plant in Linn County, Iowa.
The funding will help bring the facility, which shut down in 2020, back into operation and restore 615 megawatts (MW) of nuclear generation to the regional electricity grid.
If the Nuclear Regulatory Commission approves the required licensing, the restart could provide enough reliable electricity to serve almost 500,000 homes, while creating nearly 1,500 construction jobs and more than 450 permanent operational positions.
US Deputy Secretary of Energy James P. Danly highlighted the significance of the power station: “Returning 615 MW of reliable baseload generation will drive down electricity costs, while supporting thousands of American jobs.
“This Administration is pursuing a comprehensive nuclear strategy, restarting existing reactors, increasing the output of our nuclear fleet, and accelerating new construction, to build the abundant, affordable, and reliable power system required for American prosperity and reindustrialisation.”
Why the US is expanding nuclear infrastructure
The push to expand nuclear power is being driven partly by rapidly increasing electricity demand.
Data centres, manufacturing, electrification and other energy-intensive industries are placing greater pressure on electricity networks, increasing the need for dependable generation that can operate around the clock.
Existing nuclear plants are particularly valuable because they can provide consistent power without the weather-dependent fluctuations associated with wind and solar generation. Restarting retired facilities can also bring capacity back online faster than developing an entirely new nuclear plant.
The US government is also seeking to strengthen its domestic nuclear industry, including its ability to manufacture nuclear fuel, develop advanced reactors and maintain a skilled workforce.
Keeping existing infrastructure operating and returning viable facilities such as the Duane Arnold nuclear plant to service forms part of that broader strategy.
Duane Arnold nuclear plant moves closer to restart
The Duane Arnold Energy Center was Iowa’s only commercial nuclear power plant before it ceased operations in 2020. Its planned return comes as electricity demand continues to rise across Iowa and the wider Midwest.
The DOE’s Office of Energy Dominance Financing (EDF) said the financing forms part of wider efforts to accelerate investment in America’s nuclear fleet and strengthen domestic energy infrastructure.
The project is still subject to the necessary regulatory approvals. Once those requirements are met, the facility’s return would restore a substantial source of dispatchable, low-carbon electricity to the regional grid.
Boosting jobs and regional power supply
Beyond its contribution to electricity generation, the Duane Arnold nuclear plant restart is expected to deliver a significant economic boost.
The project is projected to support almost 1,500 jobs during construction, followed by more than 450 positions once the plant resumes operations.
The DOE said the latest financial close brings the number of nuclear plant restarts it has financed to three, alongside four concurrent conditional commitments and financial closings under the current administration.
For Iowa and the Midwest, the project could ultimately provide a significant new source of dependable electricity as demand across the region continues to grow.
