Analysis
For investors, the 125 GW data center electricity boom isn't just an infrastructure story—it's a multibillion-dollar capital allocation question. The choice between pre-revenue NuScale and dividend-paying Constellation mirrors the broader growth-vs-value debate, with nuclear's resurgence adding a powerful catalyst.
The surging electricity demands from artificial intelligence data centers are reshaping the nuclear energy investment landscape, creating a pivotal moment for contrasting plays: innovative small modular reactor developer NuScale Power versus established utility Constellation Energy. As hyperscalers like Alphabet, Amazon, Meta, and Microsoft race to secure 24/7 baseload power, nuclear energy’s high power density and carbon-free reliability have catapulted it to the forefront of the energy transition. This evolution presents a classic growth-vs-value dichotomy: NuScale promises revolutionary SMR technology that could redefine decentralized nuclear deployment, while Constellation leverages its massive existing fleet to capture immediate demand.

Goldman Sachs projects U.S. data center power demand could spike to 66 GW by 2027, accounting for up to 8.5% of peak summer demand. Bank of America adds that over the next five years, data centers could add 125 GW of new U.S. electric load, implying a compound annual growth rate of electricity demand of 4.1%. These numbers underscore an unprecedented energy surge, with training large language models requiring thousands of GPUs running for months, and AI agent loops demanding continuous, high-reliability power. Against this backdrop, both companies stand to benefit, yet their trajectories and risk profiles diverge sharply.
NuScale Power, the first company to receive U.S. Nuclear Regulatory Commission design approval for an SMR, aims to deploy factory-built reactors that can be scaled to meet specific needs, from remote data center campuses to grid-balancing applications. Its technology promises lower upfront capital costs, enhanced safety features, and faster construction timelines compared to traditional gigawatt-scale plants. However, NuScale remains pre-revenue, reliant on project milestones and regulatory progress. Its first commercial plant, the Carbon Free Power Project, faced delays and cost overruns before being canceled, but new partnerships are emerging. The company’s valuation hinges on the successful commercialization of its VOYGR SMR plants, with potential contracts from data center operators seeking dedicated, behind-the-meter nuclear power. The speculative upside is enormous, but so is execution risk.
What to Watch
Constellation Energy, by contrast, operates the largest U.S. fleet of nuclear reactors with 21 units across 12 sites, generating over 23 GW of capacity. It already supplies carbon-free power to millions of homes and businesses and has leveraged its assets to secure direct power purchase agreements with data centers. Its regulated and competitive business model provides a steady revenue stream, robust free cash flow, and a growing dividend. Constellation’s stock has rallied on market recognition of nuclear’s critical role in AI-driven load growth, and the company’s experienced operations team and existing infrastructure give it a near-term advantage. Yet, its growth is incremental compared to NuScale’s potential multipler.
From an investment perspective, the choice hinges on time horizon and risk tolerance. Constellation offers immediate exposure to the nuclear renaissance with visible earnings and a proven track record, while NuScale represents a high-beta bet on next-generation technology that could capture a significant slice of future data center demand. Regulatory tailwinds, including the ADVANCE Act and bipartisan support for nuclear, benefit both, but NuScale’s path to profitability remains uncertain. The SMR market is poised for growth, with the U.S. Department of Energy projecting up to 300 GW of potential, but first-mover advantage and execution will be key. As AI data centers become the backbone of the digital economy, nuclear power—whether from aging giants or nimble upstarts—will be a cornerstone of the energy infrastructure. Investors must decide whether to bet on the proven operator or the disruptive engineer.

How we covered this story
Every story in our finance coverage is assembled from multiple primary sources, cross-referenced for factual consistency, and scored along three independent dimensions: sentiment, operational impact, and source-cluster confidence. Single-source rumors and unverifiable claims do not pass our editorial gate. When a story shows "Verified by N sources" with N≥2, the development is independently corroborated; when N=1, we mark it explicitly so readers can weigh the signal accordingly.
Impact scoring uses a 1-10 scale weighted toward regulatory, financial, and operational consequence rather than coverage volume. A topic that runs in every outlet but moves no real decisions ranks lower than a niche regulatory filing that reshapes how operators in the finance space have to behave. Read our full methodology for the scoring rubric, our glossary for term definitions, and our trends index for the longitudinal view across the beat.
Sources are only linked to a story once they clear our classification pipeline at a minimum 35 percent relevance threshold. According to that methodology, reviewed July 2026, this follows multi-source corroboration standards recommended by journalism research bodies such as the Reuters Institute for the Study of Journalism.
