Aecon partnership selected to deliver Energy Northwest’s Cascade Advanced Energy Facility in Washington State
TORONTO, Oct. 23, 2025 (GLOBE NEWSWIRE) -- Aecon Group Inc. (TSX: ARE) (“Aecon”) announced today that Cascade Nuclear Partners, an equal joint venture comprised of Aecon, Kiewit, and Black & Veatch, is finalizing negotiations with Energy Northwest to collaboratively complete the design, planning and construction of the first four of 12 Xe-100 small modular reactors (SMR) under a progressive design-build model.
Developed by X-energy, each Xe-100 SMR is a high-temperature gas-cooled reactor that provides 80 megawatts of electricity. This first phase of the Cascade Advanced Energy Facility will generate up to 320 megawatts through the delivery of four reactor modules and will be located adjacent to Energy Northwest’s Columbia Generating Station near Richland, WA.
“The Energy Northwest SMR project is an exciting undertaking, and we are pleased to expand our role in delivering the next generation of nuclear energy plants through one of the first SMR projects in the United States,” said Jean-Louis Servranckx, President and Chief Executive Officer, Aecon Group Inc. “This project underscores Aecon’s strategic focus on executing and pursuing a growing set of nuclear opportunities in the U.S. and globally.”
In October 2024, Energy Northwest announced a multi-year agreement with Amazon focused on comprehensive environmental, safety, permitting, licensing and risk analyses for the first-ever SMR project in eastern Washington. At the completion of this robust analyses, Energy Northwest is expected to submit a construction permit application to the Nuclear Regulatory Commission. Construction is anticipated to begin by the end of the decade, with operations targeted for the 2030s.
“Bringing our full spectrum of nuclear construction expertise and multidisciplinary capabilities across our diverse operating sectors, Aecon is well positioned to harness its SMR construction experience, along with five decades of comprehensive nuclear expertise to help meet the energy needs of future generations,” said Aaron Johnson, Senior Vice President, Nuclear, Aecon Group Inc.
“Our high caliber team brings solutions to deliver some of the most formidable projects in the nuclear industry, and we look forward to safely and successfully carrying out this project working collaboratively with Energy Northwest and our partners,” said Brad Smalldridge, Vice President, U.S. Nuclear Operations, Aecon Group Inc.
“Selecting Cascade Nuclear Partners is a strategic milestone for this project, one that reflects our continued momentum for this project,” said Bob Schuetz, Energy Northwest CEO. “Their specialized knowledge in nuclear construction, collaborative approach, and strong alignment with Energy Northwest’s values gives us confidence in their ability to help deliver this critical project successfully.”
An Aecon-led construction partnership with Kiewit is currently delivering North America’s first grid-scale SMR through the Darlington New Nuclear Project. Aecon is also executing the three largest nuclear refurbishments in North America, with a growing roster of projects in the U.S. Aecon is working with Energy Northwest on the Moisture Separator Reheater Replacement at the Columbia Generating Station, completing major component replacements at the South Texas Project Generating Station and Dominion Energy’s North Anna Power Station, and recently completed the Savannah River Nuclear Solutions Dismantlement and Removal Project.
