Nuclear-Powered Data Centers: SMRs & the 165% Energy Demand Increase by 2030

Nuclear-Powered AI? How SMRs Could Save Hyperscale Data Centers from a Grid Meltdown

The AI Energy Crisis: Why Hyperscalers Are Racing Toward Nuclear SMRs

The data center industry faces an existential question: How do we power the AI boom without collapsing aging grids? According to Goldman Sachs, global data center energy demand will surge 50% by 2027 and 165% by 2030—a trajectory fossil fuels can’t sustainably support.

Enter small modular reactors (SMRs), the nuclear technology gaining unprecedented traction among tech giants. While no SMRs are operational in the U.S. today, companies like Microsoft, Amazon, and Meta are making billion-dollar bets to secure nuclear-powered futures. Here’s what’s at stake.

Data Center Energy Demand: 2023–2030 Forecast

• 2023 Baseline: Data centers consumed 55 GW globally.
• 2027 Forecast: 82.5 GW (+50%), driven by AI workloads.
• 2030 Forecast: 145.75 GW (+165%), equivalent to powering 145 million homes.

“The grid can’t keep up. Coal plants are being revived as a stopgap, but nuclear is the only scalable clean solution.”

Major Companies Betting on Nuclear SMRs

Microsoft

• Power purchase agreement to reopen Pennsylvania’s Three Mile Island.
• Capacity: 800 MW from the legacy nuclear plant.
• Timeline: Operational by 2027.

Amazon

• Data center campus adjacent to Pennsylvania’s Susquehanna nuclear plant.
• Capacity: 1.2 GW, bypassing grid bottlenecks.

Meta

• RFP for 4 GW of new nuclear energy.
• Goal: Achieve net-zero operations by 2030.

Oklo

• 20-year master agreement with Switch data centers.
• Capacity: 12 GW via modular 20 MW SMRs.
• Timeline: First units operational by 2027.

NuScale

• Two SMR plants in Ohio and Pennsylvania.
• Companies preparing for nuclear-powered campuses must ensure resilient secondary systems—cooling, redundant power, and electrical distribution. AFI helps hyperscalers design and maintain these mission-critical layers.
• Capacity: 2 GW by 2029.

When Will Small Modular Reactors Be Ready for Hyperscaler Deployment?

Despite momentum, experts warn SMRs won’t scale until the mid-2030s due to:

• Regulatory Delays: 5–7 years for permits and safety approvals.
• Technology Gaps: Integrating SMRs with existing infrastructure is complex.

The Bottom Line 

Nuclear SMRs must grow 15x by 2030 to meet a fraction of the demand. Hyperscalers are acting now to avoid grid dependency, but regulatory and technical barriers remain.

Data centers are the unlikely heroes of the energy transition. By embracing SMRs, they’re not just powering AI—they’re redefining how the world generates clean, reliable energy. The race isn’t just for AI supremacy—it’s for a sustainable future, and data centers are leading the charge.
