TerraPower, a nuclear innovation company, Evergy (NASDAQ: EVRG) and the Kansas Department of Commerce, announced today the signing of a memorandum of understanding (MOU) to explore siting TerraPower’s flagship technology, the Natrium® reactor¹ and energy storage system, within Evergy’s service territory in Kansas.

This agreement will enable the collaboration between the entities to evaluate site-specific characteristics for a potential advanced nuclear power plant, as well as explore the Natrium plant’s technical design and ability to support Evergy’s customers. Site selection will be based on an evaluation of a variety of factors including community support, the physical characteristics of the site, the ability of the site to obtain a license from the U.S. Nuclear Regulatory Commission and access to existing infrastructure.

"My administration has always supported an ‘all-of-the-above’ approach when meeting the energy needs of Kansas citizens and businesses,” Governor Laura Kelly said. “We need to explore all available sources to power the future of our great state, and I'm pleased we're using innovative methods to do just that."

“Our Natrium technology features a next-generation reactor with enhanced safety and efficiency, paired with utility-scale storage to ensure grid resilience,” said TerraPower president and chief executive officer Chris Levesque. “The TerraPower team is excited to advance conversations with Evergy, state leaders and local communities on the opportunities that the Natrium reactor and energy storage system brings to Kansas.”

“Nuclear energy has been part of Evergy’s generation mix for decades, and this next step will allow us to explore the opportunity to add reliable, non-carbon emitting advanced nuclear energy in the state of Kansas,” said David Campbell, Evergy’s chairman and chief executive officer. “This agreement supports our all-of-the-above energy strategy and will allow us to evaluate the cost, technology, and feasibility of potentially deploying Natrium advanced nuclear plants.”

“Expanding the use of nuclear energy strengthens U.S. energy independence while bringing down electricity costs for Kansas rate payers,” said U.S. Senator Jerry Moran. “TerraPower’s decision to collaborate with Evergy and invest in our state is a testament to the skill, opportunity and capabilities found in Kansas, and this partnership will help to advance energy innovation, bolster the Kansas workforce and make certain our state remains a place where business and talent can thrive.”

“Nuclear energy is the way of the future,” said U.S. Senator Roger Marshall. “Nuclear produces reliable, clean power—and a lot of it. I’m excited about the prospect of welcoming TerraPower’s Natrium reactor to Kansas and look forward to helping bring this project to fruition so that Kansans can have safe, reliable, and affordable energy.”

“In order to continue our state’s phenomenal surge in economic activity that benefits Kansas residents and communities,” Lieutenant Governor and Secretary of Commerce David Toland said, “we need to consider all innovative options that strengthen our competitive position while driving down costs for consumers. This project could do both.”

The Natrium technology features a 345 MWe sodium-cooled fast reactor with a molten salt-based energy storage system. The storage technology can boost the system’s output to 500 MW of power when needed as it is designed to keep base output steady, ensuring constant reliability, and can quickly ramp up when demand peaks — it is the only advanced reactor design with this capability.

TerraPower broke ground on the first Natrium project in 2024 in Wyoming and is positioned to be America’s next commercial-scale nuclear power plant.
