Why Nuclear Energy is Poised for Growth

For decades, nuclear energy occupied an awkward position in the American energy conversation—too politically charged to embrace, too reliable to abandon. That era is ending. A convergence of surging power demand, hyperscale data center expansion, and a genuine bipartisan policy shift has put nuclear back at the center of the clean energy discussion, and this time, the momentum feels different.

This isn't nostalgia for the atomic age. It's cold economic logic.

The Current State of Nuclear Energy

Nuclear currently supplies about 18–20% of U.S. electricity generation, making it the single largest source of carbon-free power in the country—larger than wind and solar combined. That fact surprises most people, and it probably shouldn't.

What's changed in the last two years isn't the underlying physics or even the economics of existing plants. It's the *strategic value* those plants represent. Utilities and grid operators are suddenly looking at aging nuclear facilities—assets that might have been slated for retirement—and seeing something they desperately need: firm, dispatchable, 24/7 carbon-free power.

Nuclear plants don't go offline when the sun sets or when the wind stops. That quality, once taken for granted, is now worth a premium.

The clearest signal of this reassessment came when Constellation Energy announced the restart of Three Mile Island Unit 1, rebranded as the Crane Clean Energy Center, under a 20-year power purchase agreement with Microsoft. A tech giant just signed a two-decade commitment to nuclear power. That's not a symbolic gesture—it's a load-bearing business decision.

Rising Demand for Power and Data Centers

The numbers driving nuclear's revival are staggering. U.S. electricity demand, which had been essentially flat for 15 years, is now projected to grow by 15–20% over the next decade. The primary driver? Data centers.

Generative AI workloads are uniquely power-hungry. Training large language models and running inference at scale requires massive, sustained computational power—and that means massive, sustained electricity consumption. A single hyperscale data center can draw 100–500 megawatts. Some proposed AI campuses are planning for gigawatt-scale power needs. To put that in perspective, one gigawatt powers roughly 750,000 average American homes.

The data center industry isn't just looking for electricity—it's looking for guaranteed electricity, at scale, with a credible path to carbon neutrality.

That combination of requirements essentially writes a job description that only nuclear can fully satisfy. Renewables are cheaper on a per-megawatt-hour basis, but they require substantial battery storage or grid backup to provide the reliability that hyperscale operators need. Natural gas is reliable but increasingly problematic from an ESG and regulatory standpoint. Nuclear checks every box: baseload reliability, carbon-free generation, and a physical footprint that's small relative to its output.

Amazon, Google, and Microsoft have all signed or are actively pursuing nuclear offtake agreements. This isn't a fringe strategy—it's becoming standard capital allocation practice for any tech company serious about both uptime and sustainability commitments.

Policy Changes Driving Nuclear Growth

The policy environment has shifted meaningfully, and not just at the federal level.

The Inflation Reduction Act extended and expanded nuclear production tax credits, offering up to $15 per megawatt-hour for existing nuclear plants—a lifeline for facilities that were previously uneconomic to operate. The Nuclear Regulatory Commission has been directed to streamline licensing processes, which historically have been among the most significant barriers to new nuclear development. The ADVANCE Act, signed into law in 2024, specifically targets NRC efficiency and aims to reduce licensing timelines for advanced reactor designs.

At the state level, the conversation has flipped. States like Pennsylvania and Michigan, which had been moving toward nuclear phase-outs, are now actively reconsidering plant closures. Michigan's Palisades plant is pursuing a restart—which would be the first commercial nuclear restart in U.S. history—backed by $1.5 billion in federal loans from the Department of Energy.

What's politically notable is that nuclear has become one of the few energy technologies with genuine bipartisan support. Republicans frame it as energy independence and economic development. Democrats, particularly those focused on climate, are increasingly reconciling with nuclear's carbon-free credentials. That alignment, however fragile, creates a policy window that the industry hasn't seen in decades.

The international dimension matters too. France recently reversed course on its nuclear phase-out. The UK is investing in new capacity at Hinkley Point C and exploring small modular reactors. When major European economies are doubling down on nuclear, it changes the global supply chain dynamics and signals to investors that this isn't a local or temporary trend.

The Advantages Nuclear Holds Over Alternatives

Reliability is the headline advantage, but it's worth being specific about what that means economically.

Nuclear plants operate at capacity factors above 90%—meaning they produce at or near their rated capacity more than 90% of the time. Compare that to utility-scale solar at roughly 25% and onshore wind at around 35%. This doesn't make solar or wind inferior; they serve different purposes in a balanced grid. But for industrial and commercial customers who need power to be available at all times, capacity factor is everything.

The land use efficiency of nuclear is also dramatically underappreciated. A single nuclear plant producing 1,000 megawatts occupies roughly 1.3 square miles. Equivalent solar generation would require something closer to 75 square miles. For data center developers trying to site facilities near urban power infrastructure, that distinction is increasingly relevant.

And then there's the fuel security argument. Uranium has a high energy density that makes strategic stockpiling practical. A nuclear plant can store years of fuel on-site—a resilience characteristic that no weather-dependent renewable can match.

The criticism that nuclear is too expensive to build misses an important distinction: it's expensive to build, but extremely cheap to operate once running.

The levelized cost of electricity from existing nuclear plants is among the lowest of any generation source. The capital cost problem is real, but it's primarily a problem for new greenfield construction—which is where advanced reactor designs, particularly small modular reactors, are attempting to change the math.

What the Next Decade Looks Like

The industry is betting heavily on small modular reactors as the technology that unlocks the next phase of nuclear growth. SMRs—reactors typically rated below 300 megawatts—promise factory manufacturing, faster deployment timelines, and lower upfront capital requirements than traditional gigawatt-scale plants.

Companies like NuScale, X-energy, and TerraPower are at various stages of development and regulatory approval. NuScale received NRC design certification in 2023, a significant milestone, though the economics of its first commercial project remain under scrutiny after cost escalations forced a reassessment. This is a reminder that enthusiasm and execution are different things—the SMR pathway is promising but not proven at commercial scale.

Realistically, the near-term growth in nuclear capacity will come from life extensions of existing plants and, where feasible, restarts. New large-scale nuclear construction in the U.S. faces the same labor, supply chain, and regulatory challenges it always has. SMR commercial deployment, at meaningful scale, is likely a mid-2030s story.

But the investment thesis doesn't require SMRs to deliver on every promise in the next five years. The thesis requires only that nuclear's existing fleet is preserved, valued appropriately, and contracted to customers willing to pay for its unique attributes—and on that front, the market is already moving fast.

For infrastructure investors and land developers, the signals worth watching are site selection activity around existing nuclear plants, transmission interconnection queues in markets with nuclear exposure, and the pace of corporate PPA signings in the tech sector. Where hyperscalers are signing 20-year nuclear agreements, the surrounding infrastructure ecosystem—transmission, land, cooling, fiber—follows.

Nuclear energy's growth cycle isn't speculative anymore. The contracts are real, the policy support is real, and the demand driving all of it isn't going away. The question for investors and developers isn't whether to pay attention to nuclear—it's how quickly they can get positioned before the obvious opportunity becomes a crowded trade.
