Google's Nuclear Power Plant Secures $1.9B Federal Loan to Power AI Data Centers in Iowa

Google Secures Nuclear Power for AI Expansion

The U.S. Department of Energy closed a $1.9 billion loan to finance NextEra Energy's refurbishment of the Duane Arnold nuclear plant in Iowa, marking a significant move in Google's strategy to power its AI data centers with clean energy1

. The facility, which operated for over 45 years before shutting down in 2020 following storm damage, will be repurposed to meet surging energy demands driven by artificial intelligence workloads2

.

Google announced last October it would work with NextEra Energy to restart Duane Arnold and explore deploying additional nuclear capacity nationwide. Under their multi-year agreement, Google will purchase power from the plant, making the investment financially viable and covering energy production costs2

. The tech giant also committed $7 billion to Iowa over two years for new and expanded AI and cloud infrastructure.

Addressing Surging Energy Demands of AI

The electricity demands of AI data centers have created unprecedented pressure on power grids. New data centers are expected to nearly triple the sector's electricity consumption by 20351

1

. After decades of stagnant demand growth, the sudden rise of AI coupled with broader economic electrification has left utilities scrambling for new generating sources.

Once restarted in early 2029, Duane Arnold will deliver 615 megawatts of clean, firm power to the regional grid—enough to power nearly 500,000 homes2

. The refurbishment will squeeze an additional 14 megawatts from the facility beyond its original capacity1

1

. However, just 50 megawatts will be allocated to the local power cooperative, covering only 18% of Iowa's demand growth since 2021, the year before ChatGPT launched1

Google reportedly plans to build up to six data centers near the Duane Arnold Energy Center, directly tapping into this dedicated clean power source for its AI operations1

Tech Industry's Nuclear Revival

Shuttered plants are becoming the tech industry's preferred solution for quickly securing clean power sources for AI operations. This $1.9 billion loan represents the second major federal investment in nuclear restarts, signaling the Trump administration's commitment to revived nuclear power as essential infrastructure for AI competitiveness1

Microsoft secured a similar arrangement two years ago with Constellation Energy to restart a reactor at Three Mile Island in Pennsylvania that last operated in 2019. That facility received a $1 billion Department of Energy loan and is scheduled to generate 835 megawatts when it restarts in 20281

Meta has also entered the nuclear arena, reaching agreements to support up to 6.6 gigawatts of new and existing nuclear capacity by 20352

2

. The company purchased all clean energy attributes from Constellation Energy's Clinton Clean Energy Center in Illinois, a 1.1 gigawatt facility that was facing closure before Meta's intervention. Under this arrangement, Clinton sends electricity to the local grid while Meta uses the certificates to offset emissions produced elsewhere, including at its Hyperion AI data center, which will require 10 natural gas power plants to operate and consume more electricity than all of South Dakota1

Limited Options for Future Restarts

The three power plants involved in tech partnerships—Duane Arnold, Three Mile Island, and Clinton—represent the lowest hanging fruit in the United States for nuclear restarts1

1

. According to a UtilityDive report, only one or two additional candidates exist, including San Onofre in California, though these shuttered facilities have been offline longer and would require substantially more work to bring back online1

.

The economic calculus for nuclear power has shifted dramatically since 2020, when NextEra originally mothballed Duane Arnold. At that time, cheap natural gas flooding the market made nuclear economically unappealing1

1

. The AI boom has reversed that calculation, with tech companies now willing to commit to long-term power purchase agreements that make nuclear refurbishment financially attractive.

Deputy Secretary of Energy James Danly stated the Iowa nuclear plant's restart will "drive down electricity costs," though he provided no explanation for how this would occur given that most of the facility's output is dedicated to Google rather than the broader grid1
