Brookfield announced plans in March 2026 to develop a gigawatt-scale data center campus at the U.S. Department of Energy’s (DOE) Paducah Gaseous Diffusion Plant in Kentucky, a former uranium enrichment facility. The project aims to integrate nuclear power with natural gas and battery storage to meet the high electricity and sustainability demands of artificial intelligence (AI) data centers. Data Center Dynamics reported on the initiative.
The data center campus will leverage the site’s existing nuclear infrastructure alongside power supplied by NextEra Energy’s natural gas plants and battery storage systems. Brookfield stated this combination will provide a reliable, low-carbon energy supply tailored to the continuous, high-intensity workloads typical of AI processing.
Brookfield described the development as one of the largest efforts to date to align energy-heavy AI data centers with clean and stable energy sources. The company emphasized that nuclear power ensures a steady baseline output, while NextEra’s natural gas and battery systems will manage peak loads and grid stability, critical for uninterrupted AI operations.
The campus is planned to host multiple data center buildings optimized for AI processing units, high-performance computing, and extensive data storage. Brookfield expects the site to attract hyperscale cloud providers and AI companies seeking sustainable power solutions. The integration of nuclear energy is notable given the sector’s increasing focus on reducing carbon emissions amid escalating AI computational requirements.
NextEra Energy’s role includes supplying natural gas and battery storage to supplement the nuclear base load. According to Brookfield, natural gas facilities will provide flexible backup power, balancing the intermittent nature of renewables and ensuring grid resilience. Battery storage systems will store excess energy during low demand and release it during peak periods, smoothing supply fluctuations.
Industry analysts see this project as part of a broader trend where data center developers co-locate facilities with nuclear infrastructure to meet sustainability goals. Nuclear power offers a carbon-free, reliable energy source, contrasting with many current data centers that rely heavily on fossil fuels or intermittent renewable energy.
Brookfield’s announcement comes amid growing scrutiny of AI’s environmental impact. Large AI models require vast electricity during training and inference phases, raising concerns among environmental groups and regulators. By situating data centers on a nuclear-powered campus, Brookfield aims to reduce the carbon footprint associated with AI workloads.
The DOE’s Paducah site offers additional benefits. Its existing security infrastructure and regulatory framework from its uranium enrichment history may expedite permitting and construction compared to new developments. The location also benefits from favorable grid interconnection options, supporting the addition of large data center loads.
Local and federal stakeholders have expressed support for revitalizing the Kentucky site to promote economic development and advance clean energy goals. The DOE reportedly supports repurposing legacy nuclear sites for modern energy and technology uses, aligning with national decarbonization strategies.
Brookfield highlighted the strategic importance of battery storage in addressing the variability of integrating multiple power sources. Battery systems enhance reliability by storing excess energy during off-peak times and supplying it during demand spikes, critical for AI data centers to avoid costly downtime.
While in early stages, Brookfield indicated construction could begin in late 2026, with phased operations ramping up over subsequent years. The company plans close collaboration with the DOE, NextEra, and regional regulators to ensure compliance with environmental and safety standards.
The project arrives at a time when AI infrastructure expansion is intensifying energy consumption concerns. Brookfield’s approach of combining nuclear power with natural gas and battery storage may serve as a model for future data center developments seeking to balance energy intensity with sustainability.
Historically, nuclear power has been underused in commercial data centers due to regulatory and capital cost challenges. However, environmental imperatives and technological advances are prompting renewed interest in nuclear energy for powering next-generation computing infrastructure. This initiative at the Kentucky nuclear site exemplifies that shift.
Brookfield’s partnership with NextEra underscores the value of diversified energy portfolios for AI infrastructure. Natural gas plants enable rapid load adjustments, batteries provide grid stability, and nuclear energy offers steady baseline power. Together, they aim to deliver the reliability and sustainability required for AI workloads.
As AI models grow larger and more complex, infrastructure must evolve to support their energy demands without worsening environmental impacts. Brookfield’s gigawatt-scale campus project at a historically significant nuclear site represents a concrete step toward integrating innovative energy solutions with advanced computing needs.
