US Power Shortage: How Small Modular Nuclear Reactors Could Fill the Gap

Surging Demand: After decades of flat growth, U.S. electricity demand is projected to increase by 20% to 100% over the next 15 years .
Key Drivers: This surge is fueled by energy-hungry AI data centers, which require power equivalent to medium-sized cities, and the onshoring of semiconductor manufacturing.
Energy Gap: Peak power demand is expected to outstrip peak supply by 2028, necessitating new generation sources.

Compact Efficiency: Unlike traditional gigawatt-scale plants (which power about 1 million homes), SMRs are approximately 300 megawatts and require much less space, making them ideal for “power-dense” locations
Standardization and Cost: Traditional plants were often “bespoke,” leading to high costs. SMRs are designed to be standardized products, allowing companies to lower costs through volume and factory-based construction
Zero-Carbon Energy: SMRs provide a reliable, zero-carbon alternative to fossil fuels, helping companies like “hyperscalers” (large data center operators) meet sustainability commitments

Projected Deployment: While no SMRs are currently operating in the U.S., GE Vernova expects to have them running in the early 2030s
Canada Leading: A BWRX-300 reactor is already being built in Ontario, Canada, and is expected to be online by the end of the decade
U.S. Milestones: GE Vernova and the Tennessee Valley Authority (TVA) are awaiting a construction permit from the Nuclear Regulatory Commission, expected by late 2026, with construction potentially starting in 2027

Bipartisan Support: Nuclear energy is one of the few power sources with general consensus across both sides of the political aisle
Funding and Partnerships: * The Department of Energy recently provided $400 million in funding support for the TVA project
- A $100 billion Memorandum of Understanding (MOU) was signed with the U.S. government to industrialize SMRs, involving potential investment from Japan through partners like Hitachi
Resource Challenges: Expanding nuclear capacity will require a significant increase in the domestic supply of uranium, as the U.S. currently depends heavily on other countries for this fuel
