Google-backed Iowa nuclear plant gets $1.9B US loan
The U.S. Department of Energy has awarded NextEra Energy a $1.9 billion loan to refurbish the Duane Arnold Energy Center in Iowa, a nuclear plant shut down since 2020. Google has signed a long-term power purchase agreement to secure electricity from the plant, which is expected to restart in Q1 2029, pending NRC approval, and generate 615 megawatts, with 50 megawatts reserved for a local cooperative. Google is reportedly considering building up to six data centers nearby. This reflects a broader trend of tech companies like Microsoft and Meta securing clean, firm power for AI operations, with similar deals for the Crane Clean Energy Center and Palisades. In contrast, Germany continues its nuclear phase-out, highlighting energy policy as a key factor in digital competitiveness.
This is significant for the tech industry as it underscores the growing importance of nuclear power to meet the energy demands of AI data centers, a trend that indirectly affects the adtech ecosystem which relies on these data centers for operations.

Google and Constellation sign nuclear uprate deal
Constellation Energy has signed a deal with Google to add 890 megawatts of additional nuclear capacity to the PJM Interconnection grid, the largest in the U.S. The power will come from upgrades to 11 existing nuclear plants in Illinois, Pennsylvania, and New Jersey, including modernizing turbines, steam generators, and control systems. This approach, known as 'uprates,' is favored by big tech companies like Google because it is cheaper and quicker than building new plants or developing small modular reactors. Constellation's shares rose 15% on the news. The deal follows a similar agreement with Amazon last week to add 190 megawatts at Calvert Cliffs. Analysts at Evercore ISI note that other independent power producers like Vistra and Talen Energy may benefit from similar uprate opportunities, as could uranium enrichers like Centrus Energy.
Google Powers Up with Major Clean Energy Deal
Google announced a partnership with Michigan utility DTE to add 2.7 gigawatts of new capacity to power a planned data center near Detroit. The package includes 1.6 GW of solar, 400 MW of four-hour battery storage, 50 MW of long-duration storage, 300 MW of additional 'clean resources' (unspecified sources such as wind, hydro, nuclear or geothermal), and 350 MW provided via demand-response programs. The deal will use Google’s Clean Transition Tariff, a mechanism the company has used previously in a similar agreement with Xcel Energy in Minnesota. Google also pledged a $10 million Energy Impact Fund aimed at reducing utility bills through measures like home insulation. Several details remain unresolved or not publicly clarified, including the exact definition of 'additional clean resources.'
Google Buys Largest Solar+Battery Project Near xAI Plant
Google announced its largest solar and battery storage purchase to date: the Steel River Energy Center in Arkansas. Google is investing alongside developer Cypress Creek Energy and has contracted the full output of the project's first two phases, which add 1 GW of solar capacity and 1.9 GWh of battery storage. When completed in three phases (final connection scheduled for 2029) the facility is expected to total about 1.8 GW of solar and 2.9 GWh of battery storage; Cypress Creek secured $3.5 billion in financing for the first two phases. The project will feed electricity to the grid to offset Google’s data-center demand and support hourly matching of clean power. The announcement contrasts with xAI’s operation of an unpermitted natural-gas power plant roughly 40 miles south and wider concerns about fossil-fuel use for data centers.
