The nuclear company behind the small modular reactors planned for north of Richland has launched the process to sell common stock in the company via the Nasdaq stock exchange. 

It’s unclear when X-energy’s initial public offering would launch, as the company’s plans have yet to be reviewed by the U.S. Securities and Exchange Commission, according to a release. The number of shares to be offered and potential pricing has not been released.  

The Cascade Advanced Energy Facility is a joint venture of Energy Northwest, Amazon and X-energy.  

The project, announced in late 2024, calls for construction of four of X-energy’s Xe-100 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.
