TerraPower, a nuclear innovation company, and Sabey Data Centers (SDC), a leading data center developer, owner and operator, announced a memorandum of understanding to develop a strategic collaboration agreement. This initiative aims to leverage advanced nuclear Natrium plants into SDC’s current and future data center operations.
“Sabey Data Centers is dedicated to pioneering sustainable energy solutions to support our customers’ growth,” says Tim Mirick, President of Sabey Data Centers. “Our strategic collaboration with TerraPower represents a substantial move toward integrating clean, innovative power technologies into the heart of our operations.”
SDC is one of the largest private data center providers in the world, with over 20 years of experience in developing, constructing and operating data centers across the nation. They have led sustainability efforts within the data center industry, focusing on whole-building energy efficiency, with a goal of achieving carbon-free energy operations across their portfolio.
Innovative Advanced Nuclear
TerraPower began construction on America’s first advanced nuclear project in 2024, near a retiring coal facility in Wyoming. The strategic collaboration includes exploring new Natrium plants in the Rocky Mountain region, as well as Texas, to support growing power needs for SDC-owned data centers.
Due to the scope of the opportunity, TerraPower and SDC will explore multiple project execution structures to meet the exponential demand in data center energy needs with TerraPower’s innovative advanced nuclear and storage Natrium technology.
"At its heart, TerraPower is an innovation-driven company, and we are thrilled to collaborate with Sabey to address the surging energy demands of data centers with clean, reliable and adaptable solutions like the Natrium technology," said Chris Levesque, TerraPower President and CEO. "The energy sector is transforming at an unprecedented pace after decades of business as usual, and meaningful progress will require strategic collaboration across industries. Together, we can ensure advanced nuclear technology plays a vital role in securing a clean, resilient energy grid."
What Is Natrium Technology?
Natrium technology represents a pioneering advancement in nuclear energy, tailored specifically to meet the evolving demands of data centers. Unlike traditional nuclear reactors, Natrium features a 345 MW sodium-cooled fast reactor complemented by a patented molten salt-based energy storage system.
This unique combination enables the system to efficiently manage power output, ensuring steady reliability while swiftly ramping up to 500 MW during peak demand periods.
This adaptability makes Natrium particularly well-suited for the intensive power requirements of data centers, where uninterrupted and scalable energy supply is critical. Notably, Natrium is the sole advanced nuclear technology currently advancing towards commercial deployment in the United States.
With a pending construction permit and ongoing development under the U.S. Department of Energy’s Advanced Reactor Demonstration Program, Natrium is set to establish the first commercial-scale advanced nuclear power plant in the country by 2030. Its innovative design and operational flexibility position Natrium as a pivotal solution to supporting the burgeoning energy needs of modern data centers in the coming years.
