You can now buy stock in the company planning to build the next generation of nuclear reactors north of Richland in partnership with Amazon and Energy Northwest. 

Maryland-based X-energy was first listed for trade on the NASDAQ Global Select Market on April 24 under the ticker symbol XE, according to the company’s social media. The initial public offering of 44 million shares of Class A common stock was priced at $23 per share. It hit a peak of nearly $37 per share on April 28 and sat at just under $33 per share as of May 11.

X-energy’s Xe-100 small modular nuclear reactors, or SMRs, will be the technology that powers the planned Cascade Advanced Energy Facility.  

The project, announced in late 2024, calls for construction of four SMRs, capable of generating 320 megawatts of power, which Amazon will have claim to. 

Renderings released by Amazon several months ago show what the facility would look like at full build-out, generating 960 megawatts that would contribute to the region’s power grid.   

Construction is anticipated to begin in the next five years. Energy Northwest named Cascade Nuclear Partners – a joint venture made up of Black & Veatch, Aecon and Kiewit Nuclear Solutions Co. – as the builder for the project.
