Google is bringing a nuclear power plant back to life to feed its AI data centers

In a bold move to address the surging demand for low-carbon energy, Google has teamed up with NextEra Energy to rejuvenate Iowa's only nuclear power facility, the Duane Arnold Energy Center. This plant, which ceased operations in 2020, is projected to resume electricity generation by early 2029, pending the necessary regulatory approvals. Once it is back online, Google plans to acquire power from the 615-megawatt facility, which will serve as a 24/7 carbon-free energy source to support its expanding cloud and artificial intelligence operations in Iowa. This initiative aims not only to bolster Google’s infrastructure but also to enhance the reliability of the local energy grid, as highlighted in the companies' recent press release. The Central Iowa Power Cooperative, the largest energy provider in the state, has also agreed to purchase any excess electricity generated by the plant. This revival comes at a time when the nuclear energy sector is seeking to regain its footing in the face of competition from natural gas and other renewable sources, which have been favored due to lower operational costs and safety concerns. With energy consumption in the U.S. reaching unprecedented levels, particularly due to the rapid expansion of data centers, the interest in nuclear power is resurging. The U.S. Energy Information Administration reported that electricity consumption reached a record high in 2024, a trend that could escalate as tech giants invest heavily in power-intensive AI infrastructures. The project in Iowa is not an isolated case; it reflects a broader trend of collaboration between tech firms and the nuclear sector, including partnerships like that of Constellation Energy and Microsoft, as well as Oracle’s initiative to construct a data center powered by small nuclear reactors. Ruth Porat, Alphabet and Google’s president and chief investment officer, noted that this partnership exemplifies the necessary investments to expand energy capacity nationwide. It aims to ensure reliable and clean power while fostering job creation in an AI-driven economy. However, Google's journey towards sustainability has seen some turbulence. In June, the company discreetly removed its 2030 net-zero carbon emissions target from its sustainability website as it ramped up its AI initiatives. Additionally, data center projects across the U.S. have faced increasing public scrutiny, evidenced by Google’s recent decision to abandon plans for a new data center in Indiana due to community concerns about resource allocation and environmental impact. Iowa, in contrast, has shown a welcoming stance towards such initiatives, with Google having invested over $6.8 billion in state data centers thus far. Local lawmakers have expressed their support for the revival of the Duane Arnold Energy Center, with State Senator Charlie McClintock emphasizing the positive implications for job creation and energy reliability in the region. "Bringing Duane Arnold back online is a big win for Linn County and the entire state of Iowa," he stated, reinforcing the commitment to keep the lights on for both residents and businesses.
