Behind-the-meter (BTM) Small Modular Reactors (SMRs) are emerging as a transformative energy solution for power-intensive artificial intelligence (AI) data centers, addressing the growing challenges of electricity availability, grid reliability, and carbon-reduction targets. The market was valued at approximately USD 500 million in 2025 and is projected to reach nearly USD 20,121 million by 2035, expanding at a compound annual growth rate (CAGR) of 44.7% during the forecast period from 2026 to 2035.

The accelerating adoption of generative AI, machine learning, cloud computing, and advanced analytics is fundamentally reshaping global electricity demand patterns. AI-focused data centers require significantly higher power densities than traditional computing facilities due to the deployment of large-scale GPU clusters, specialized AI accelerators, and continuously operating computational workloads. As organizations expand AI capabilities, the scale of electricity consumption required for data processing, model training, and inference operations is rising dramatically.

Noteworthy Market Developments

The behind-the-meter nuclear (SMR for data centers) market is witnessing increasing competition among advanced reactor developers as technology companies, utilities, and infrastructure investors seek reliable, carbon-free energy solutions to support the rapid expansion of artificial intelligence, cloud computing, and high-performance computing facilities. Oklo has established a prominent position in the emerging behind-the-meter nuclear market through its focus on compact fast-fission microreactors designed for distributed and dedicated energy applications.

Kairos Power has strengthened its market position through the development of fluoride salt-cooled high-temperature reactor technology and strategic partnerships with major technology companies. X-energy is another major participant in the behind-the-meter nuclear market, primarily through its development of high-temperature gas-cooled reactor technology.

NuScale Power holds a unique position in the SMR industry due to its regulatory achievements and early progress toward commercialization. The company developed one of the first SMR designs to receive certification from the U.S. Nuclear Regulatory Commission, providing it with an important regulatory advantage compared with many competing advanced reactor developers. Westinghouse Electric Company is leveraging its decades of nuclear industry expertise to develop advanced microreactor solutions designed specifically for decentralized and behind-the-meter energy applications.

Core Growth Drivers

Grid saturation and infrastructure constraints have emerged as major factors accelerating the growth of the behind-the-meter nuclear (SMR for data centers) market. The rapid expansion of artificial intelligence, cloud computing, and high-performance computing applications has created unprecedented electricity demand from hyperscale data centers, placing significant pressure on existing utility networks. Traditional power grids in many regions are struggling to accommodate the pace and scale of new electricity requirements due to limited generation capacity, aging transmission infrastructure, and lengthy interconnection processes. These challenges are encouraging technology companies and infrastructure developers to explore dedicated power solutions, including behind-the-meter small modular reactors (SMRs), to secure reliable electricity supplies without relying solely on constrained grid systems.

Emerging Opportunity Trends

Gen IV reactor adoption represents an emerging opportunity trend that could significantly influence the long-term growth trajectory of the behind-the-meter nuclear (SMR for data centers) market. As demand for reliable, low-carbon electricity continues to accelerate due to artificial intelligence, cloud computing, and high-performance computing expansion, developers and energy consumers are increasingly exploring advanced reactor technologies beyond conventional designs. Generation IV reactors are gaining attention because of their potential to deliver improved safety characteristics, higher operating efficiencies, enhanced fuel utilization, and greater flexibility for integration with energy-intensive industrial applications such as hyperscale data centers.

Barriers to Optimization

Regulatory pushback is expected to remain one of the key challenges that could hamper the growth of the behind-the-meter nuclear (SMR for data centers) market. Although the increasing electricity demands of hyperscale data centers have accelerated interest in dedicated nuclear power solutions, the rapid emergence of behind-the-meter (BTM) and co-located power configurations has introduced complex regulatory, economic, and market design questions. Policymakers and energy regulators are increasingly examining how these projects interact with existing electricity markets, transmission infrastructure, and utility rate structures. As regulatory reviews become more comprehensive, project approvals may face longer timelines, creating uncertainty for developers, investors, and technology companies planning large-scale SMR deployments.

Detailed Market Segmentation

By reactor type, Light-Water Small Modular Reactors (SMRs) accounted for the largest share of the behind-the-meter nuclear (SMR for data centers) market in 2025, primarily due to their technological maturity, well-established regulatory pathways, and extensive operational track record. As the market transitions from concept development to commercial deployment, project developers and hyperscale data center operators have demonstrated a strong preference for reactor technologies that offer proven performance, predictable licensing processes, and lower execution risks.

By configuration, the co-located (grid-intertied) segment accounted for the largest share of the behind-the-meter nuclear (SMR for data centers) market, driven by its ability to combine the reliability of dedicated nuclear generation with the operational security of an interconnected electricity grid. As hyperscale data centers continue to expand their artificial intelligence (AI), cloud computing, and high-performance computing capabilities, uninterrupted power availability has become a fundamental operational requirement. Co-located grid-intertied SMR configurations address this need by allowing reactors to directly supply electricity to data center campuses while maintaining a connection to the regional transmission network.

By offering, reactor equipment, the largest share of the behind-the-meter nuclear (SMR for data centers) market is reflected, reflecting the capital-intensive nature of deploying small modular reactors (SMRs) to support next-generation data center infrastructure. During the early stages of market development, investment activity is heavily concentrated on establishing the core physical assets required for reactor construction and operation. Since commercial deployment of SMRs is still in its initial growth phase, the majority of project expenditure is directed toward acquiring and installing reactor equipment rather than ongoing operational or maintenance services.

By end user, hyperscalers accounted for the dominant share of the behind-the-meter nuclear (SMR for data centers) market in 2025, driven by their rapidly expanding investments in artificial intelligence (AI), cloud computing, and high-performance computing infrastructure. The accelerating adoption of generative AI applications has fundamentally transformed data center power requirements, as large language models, AI training clusters, and inference workloads require significantly greater computational capacity than conventional cloud services. These advanced workloads operate continuously and demand highly reliable, uninterrupted electricity, making energy availability a critical factor in hyperscaler infrastructure planning.
