GE Vernova, the energy spinoff of General Electric, is aiming for a dominant role in the burgeoning small modular reactor (SMR) market. Their BWRX-300 reactor promises a cost-effective and scalable solution to the world’s growing energy needs and climate change challenges, potentially revolutionizing how nuclear power is deployed and perceived. By focusing on a simpler, more modular design and securing strategic partnerships, GE Vernova is positioning itself to capture a significant share of this emerging market, impacting both established utilities and tech giants alike.

GE Vernova’s Ambitious Nuclear Power Play with Small Modular Reactors

The BWRX-300: A Game Changer in Nuclear Power?

For decades, large-scale nuclear power plants have been plagued by massive cost overruns and lengthy construction delays. Nicole Holmes, chief commercial officer at GE Hitachi (GE Vernova’s nuclear unit), told CNBC that “affordability has been the real challenge for nuclear through the many years.” The BWRX-300, however, represents a departure from this problematic trend. Its simpler design, featuring fewer components and significantly less concrete and steel, promises a significant reduction in construction costs—estimated at $2 billion to $4 billion compared to the $10 billion to $15 billion for a traditional large-scale plant. While the BWRX-300 generates 300 megawatts of electricity—enough to power more than 200,000 homes—its modular nature allows for flexible deployment; Holmes notes that “you could put four of these on a site and get the same output as you would from a single large reactor“.

Smaller Scale, Bigger Impact

The smaller size of the BWRX-300 offers several key advantages besides cost-effectiveness. Its reduced footprint allows for deployment in locations unsuitable for larger reactors, increasing the geographical reach of nuclear power. The ability to build and deploy these reactors in stages, achieving commercial output while others are still under construction, further reduces risk and accelerates returns on investment. This modularity also provides a greater degree of resilience; if one unit experiences an issue, the rest of the facility continues to operate.

Strategic Partnerships and Market Expansion

GE Vernova is not pursuing this ambitious goal alone. In March 2023, a $500 million collaboration agreement was signed with Ontario Power Generation, the Tennessee Valley Authority (TVA), and Synthos Green Energy in Poland. This partnership signifies a commitment to creating a standardized reactor design that can be efficiently replicated across multiple regulatory environments, minimizing the challenges associated with site-specific customization. Holmes emphasizes the importance of this collaboration, stating that “we’re working on a plant that can be deployed in many, many places across many, many regulatory regimes and still be the same fundamental plant.”

North American Deployments and International Interest

The first commercial contract for the BWRX-300 in North America was awarded to Ontario Power in January 2023, marking a significant milestone for SMR technology. The reactor is slated to come online in 2029 at the Darlington Nuclear Generating Station. Ontario Power plans to deploy three more BWRX-300 reactors at the same location. In the United States, TVA is actively considering building a BWRX-300 at its Clinch River site, having already received an early site permit from the Nuclear Regulatory Commission. TVA’s Scott Hunnewell explained that SMRs are inherently less risky than larger reactors due to their smaller scale and more manageable construction timelines; “If you have a gigawatt scale plant where your construction timeline starts at eight years and then gets longer, your interest expenses really start to accrue and really drive your cost up,” Hunnewell noted. “The SMR just overall, it’s a smaller bite at the apple, a lot less risk associated with it.”

The Tech Sector’s Embrace of Nuclear Power

Beyond the traditional utility companies, the tech sector is emerging as a key driver in the resurgence of nuclear energy. Driven by the immense power demands of data centers and artificial intelligence, companies like Microsoft, Amazon, and Google are making significant investments in nuclear power. Microsoft’s 20-year power purchase agreement with Constellation Energy to support the revival of the Three Mile Island plant is a prime example. These investments are not just about power acquisition; they are also about ensuring a stable and reliable energy source to meet their rapidly expanding needs. Holmes notes that “as utilities think about deploying additional capacity, these large tech companies could be an off taker and agree to power purchase prices that support deployment of these early units and early technologies.” This strategic partnership between utilities and tech giants promises to provide a crucial financial boost for the development of SMR technology and a more sustainable energy future.

A Sustainable Energy Future?

GE Vernova’s ambitions for the BWRX-300 are substantial, aiming for a significant market share by the mid-2030s. While challenges remain, the company’s approach—focused on affordability, streamlined design, and strategic partnerships—signals a potential shift in the nuclear power landscape. The BWRX-300 shows promise not just for utilities but also for technology companies needing massive and reliable power supplies, showcasing the potential of a greener and more sustainable energy future fuelled by a revitalized nuclear power industry.
