As of October 16, 2025, Amazon announced that the planned Cascade Advanced Energy Facility in Washington will deploy 12 small modular reactors (SMRs). [1] The facility will be built by Energy Northwest with funding from Amazon. Three 320-MW sections will together comprise a 960-MW plant, in contrast with traditional nuclear power facilities with a 1-GW plant. The SMRs will be supplied by X-energy, which received $500 million in Series C funding from Amazon last year, using the company’s advanced nuclear reactor design. The facility will be built outside Richland, Washington, near Energy Northwest’s Columbia Generating Station. Construction is expected to commence at the end of the decade, with operations targeted to start in the 2030s. The SMRs will be the Xe-100 design, a high-temperature gas-cooled reactor developed by X-energy, each module of which can provide 80-MW of full-time electricity.
