Google plans to revive Iowa nuclear plant for data centers

A 2020 storm shut down Iowa's only nuclear power plant prematurely. Google now aims to reopen it to supply energy for nearby data centers. Concerns arise over extreme weather risks in tornado-prone areas.

In 2020, a destructive storm forced the premature closure of Iowa's sole nuclear power facility, the Duane Arnold Energy Center. This event highlighted vulnerabilities in nuclear infrastructure amid increasing extreme weather events.

Google has announced plans to bring the plant back online, specifically to power its expanding data centers in the region. The initiative seeks to meet the growing energy demands of the company's operations while tapping into a reliable, low-carbon energy source.

However, the location in tornado country raises safety questions. Will severe storms pose ongoing threats to the reactor's operations and integrity? This development is part of broader efforts to integrate nuclear power with tech infrastructure, but it underscores tensions between energy needs and climate risks.

The story originates from Inside Climate News and is featured in the Climate Desk collaboration, emphasizing environmental and energy policy intersections.

A report promoted by the conservative-leaning nonprofit Power the Future said natural gas, coal and nuclear plants generated the bulk of U.S. electricity during Winter Storm Fern, while wind and solar output fell during the storm’s coldest, darkest hours. The findings circulated amid the Trump administration’s renewed pushback on wind power, including a December 2025 move to suspend five offshore wind projects on the East Coast.

Documents indicate Google plans to operate one of the largest data centers in the United States in southeast Nebraska, powered by a Tenaska natural gas plant that could generate up to 3,000 megawatts. The project, which may incorporate carbon capture technology, hinges on a state bill allowing private power plants to connect to the public grid. Tenaska has secured options on over 2,600 acres for the site.

Data center developers in Utah and elsewhere have requested exemptions from federal pollution regulations to meet the surging energy demands of artificial intelligence infrastructure. Companies like Novva and Thunderhead argued that such relief is essential for national security amid competition with China. Although the requests highlight the industry's challenges, none appear to have been granted for these projects.

Tech leaders like Elon Musk and Jeff Bezos propose launching data centres into orbit to power AI's massive computing needs, but experts highlight formidable hurdles. From vast solar panels and cooling issues to radiation risks, building such facilities in space remains far off. Projects like Google's 2027 prototypes show early interest, yet production-scale viability is distant.

The rapid expansion of data centres driven by artificial intelligence poses risks to South Africa's already strained electricity and water supplies. Global forecasts predict a sharp rise in energy demands, with local facilities already consuming significant power. Experts urge greater transparency and resource management to mitigate potential shortages.

Microsoft has outlined measures to act as a 'good neighbor' in areas hosting its data centers, aiming to prevent increases in local utility bills. The company is responding to rising public concerns about the energy demands of its infrastructure. This includes advocating for higher electricity rates specifically for data centers.

The Trump administration has ordered a Colorado coal plant to remain on standby amid claims of an energy emergency. This decision targets Craig Station's Unit 1, scheduled for closure at year's end, despite state assessments deeming it unnecessary for grid reliability. The move highlights ongoing efforts to prop up coal amid economic and environmental challenges.
