Global SMR Capacity Forecast to Surge Sixfold by 2030

Why It Matters

The rapid SMR expansion could reshape the low‑carbon power mix and create new investment opportunities, but early project success is essential to unlock financing and prove cost viability.

Key Takeaways

• SMR capacity could rise sixfold by 2030, 100x by 2040.
• China leads with diverse SMR tech; US pipeline grows but faces risk.
• Data centers drive demand, partnering with SMR developers.
• Over 90% of SMR projects still in permitting stage.
• Early successes crucial for financing models and cost containment.

Pulse Analysis

The forecasted explosion of small modular reactors reflects a broader shift toward resilient, carbon‑free baseload power. As nations grapple with grid reliability and climate targets, SMRs offer a compact, scalable alternative to large nuclear plants. Their ability to provide firm electricity makes them attractive for energy‑intensive sectors such as data centers, where tech giants are already exploring joint ventures with developers. This demand surge aligns with policy incentives that prioritize energy security and decarbonization, positioning SMRs as a strategic asset in the next decade.

Regional dynamics underscore the technology’s versatility. China is pursuing a portfolio that includes light‑water, high‑temperature gas, and molten‑salt designs, leveraging its industrial capacity to accelerate prototypes. South Korea focuses on integral pressurised water reactors with desalination capabilities, while Europe—particularly the UK, Canada, and Central‑Eastern nations—pushes regulatory reforms to streamline procurement despite cost pressures. The United States, buoyed by recent regulatory reforms and public funding, is building a pipeline, yet it remains hampered by supply‑chain readiness and the high risk of first‑of‑a‑kind projects.

For investors and policymakers, the SMR outlook hinges on early project outcomes. Successful pilots can trigger risk‑sharing mechanisms such as contracts for difference, regulated asset base models, and capacity payments, unlocking private capital at scale. Conversely, delays or cost overruns could dampen market confidence and stall the transition to low‑carbon firm power. As the sector moves toward commercial operation in the mid‑2030s, aligning financing, regulatory harmonisation, and public acceptance will be critical to converting the projected capacity surge into tangible grid contributions.
