US Energy Department lends $1.9B to restart Iowa nuclear plant for Google's data centers
NextEra Energy received a $1.9 billion loan from the U.S. Department of Energy to refurbish the Duane Arnold Energy Center, which Google plans to use for nearby data centers. The restart is scheduled for 2029, with only 50 megawatts set aside for local cooperative. This is the second such loan, reflecting tech companies' growing need for clean power for AI data centers.
The Duane Arnold facility ceased operations in 2020 following severe storm damage, and its owner initially chose to idle it due to an abundance of inexpensive natural gas. The new financing will boost its capacity to 615 megawatts, with a modest 50 megawatts reserved for the local cooperative, covering a fraction of recent state demand growth.
This federal backing follows a similar loan for the Three Mile Island restart, which Microsoft has contracted to receive 835 megawatts from by 2028. Meanwhile, Meta is purchasing environmental credits from an Illinois nuclear plant to offset the massive power needs of its upcoming AI campus, illustrating a broader tech-sector pivot toward revived atomic generation.
The resurgence of dormant nuclear plants could reshape regional electricity markets, potentially benefiting local ratepayers if restart costs are managed well, though the allocation of most output to tech giants may limit direct consumer savings. Communities near these sites could see economic boosts from construction jobs, while grid operators may gain reliable, carbon-free baseload power. However, the long-term affordability and environmental trade-offs of relying on aging reactors for AI expansion remain open questions.
