The Pragmatism of Power: Why Google is Betting on Nuclear Ruins

Rather than waiting for futuristic energy breakthroughs, tech giants are reviving mothballed reactors to fuel the AI boom.
For years, the conversation around clean energy for the tech sector has been dominated by the promise of future innovations. But as the electricity demands of artificial intelligence scale toward a breaking point, Google and its peers are discovering that the most viable path to net-zero isn't through new gadgets, but through the aggressive deployment of existing, proven baseload power.
As TechCrunch first reported, Google is focusing its efforts on the Duane Arnold Energy Center in Iowa. The facility has been dormant since 2020, when it was mothballed by owner NextEra Energy following damage from an intense rainstorm. At the time, the availability of cheap natural gas made nuclear power economically unattractive. Today, the calculus has shifted. To support its AI ambitions, Google is reportedly planning to build up to six data centers near the site.
This strategy is being backed by significant federal support. TechCrunch reports that the U.S. Department of Energy has provided NextEra Energy with a $1.9 billion loan to finance the refurbishment of the Iowa plant. James Danly, Deputy Secretary of Energy, stated that the plant's scheduled 2029 restart will "drive down electricity costs," though he did not provide specific details on the mechanism for those savings. NextEra CEO John Ketchum noted during a previous earnings call that 50 megawatts will be reserved for the local power cooperative, covering 18% of Iowa's demand growth seen since 2021.
Google is not alone in this pursuit of "low hanging fruit." The trend of reviving shuttered assets is becoming a blueprint for the industry. TechCrunch notes that the Department of Energy previously extended a $1 billion loan to Constellation Energy to restart a reactor at Three Mile Island, a project tied to a deal Microsoft signed two years ago. That reactor, which last operated in 2019, is expected to generate 835 megawatts upon its 2028 restart.
Similarly, Constellation Energy’s Clinton Clean Energy Center in Illinois avoided closure after Meta emerged as a customer. While the 1.1 gigawatt plant sends electrons to the local grid, Meta is purchasing the clean energy attributes to offset emissions from other sources. This is a critical hedge for Meta; TechCrunch reports that the company's Hyperion AI data center will require 10 natural gas power plants to operate and, if finished, will consume more electricity than the entire state of South Dakota.
The urgency is driven by a massive spike in demand. TechCrunch reports that new data centers are projected to nearly triple the sector's electricity needs by 2035. While other candidates for revival exist—such as San Onofre in California—a UtilityDive report suggests these would require significantly more work due to how long they have been offline.
By focusing on the Duane Arnold facility, NextEra will actually increase the plant's capacity by 14 megawatts during refurbishment, bringing the total to 615 megawatts. This shift toward reviving legacy assets signals a pragmatic realization: when the goal is firm, clean power at scale, the fastest route to the future is often found in the infrastructure of the past.
