Terrestrial Energy Inc., a developer of small modular nuclear plants using advanced reactor technology, today announced a collaboration with Ameresco, Inc., (NYSE: AMRC), a leading energy solutions provider, to advance the commercial deployment of Terrestrial Energy’s IMSR plant. The collaboration covers site identification and IMSR plant project development, design, licensing, construction, operation across the United States.
The collaboration is strategically focused on delivering customized, scalable, reliable, clean, and cost-competitive energy for data center and industrial applications, combining the competitive capabilities of Terrestrial Energy’s innovative IMSR nuclear plant with Ameresco’s expertise in energy systems’ design, hybridization, integration and operation. Integration of energy systems is expected to include the use of a natural gas-fired energy bridge in IMSR plant operation to enable early electricity delivery well in advance of IMSR nuclear systems being completed and brought to commercial operation.
The design of Terrestrial Energy’s IMSR plant is uniquely suited for such applications due to the IMSR plant’s thermal, steam and electric supply systems being remote and isolated from the plant’s regulated nuclear systems, unlike conventional nuclear plants that use Light Water Reactor technology. As a result, these remote and isolated systems can be customized and hybridized with other energy systems, such as natural gas, to meet site-specific and application-specific needs, delivering tailored, customer-focused and cost-competitive solutions with valuable commercial implications.

Our IMSR plant excels in its capacity to be adapted and customized to market needs in a grid congested world,” said Simon Irish, CEO of Terrestrial Energy. “Ameresco’s proven track record in energy system integration creates a powerful platform to develop IMSR plant projects that meet the emerging requirements of rapidly growing demand for reliable, carbon-free energy across multiple industrial sectors.”
“Our collaboration with Terrestrial Energy reflects our commitment to expanding the capabilities of our clean energy portfolio,” said Nicole Bulgarino, President of Federal Solutions and Utility Infrastructure at Ameresco. “By exploring hybrid energy systems that leverage the IMSR plant’s heat and power output, we’re enhancing our ability to deliver reliable, cost-effective, and sustainable solutions tailored to the evolving needs of data centers and industrial customers.”
Terrestrial Energy is developing IMSR plant projects across multiple sites in the U.S. In addition to its adaptability, these projects leverage the plant’s small and modular siting capabilities, and the plant’s capacity to supply zero-carbon, high-temperature thermal energy for high-efficiency, low-cost electric power generation, and direct industrial process heat use. Furthermore, as the company pursues fleet deployment, its supply chain strategy leverages existing nuclear industry supply capabilities, which includes its use of nuclear fuel at standard enrichment and avoids the use of HALEU fuel.
Today’s announcement builds on recent commercial momentum, including Terrestrial Energy’s selection by Texas A&M University to site a commercial IMSR plant at its RELLIS campus. The company’s market leadership is further demonstrated by its completion of Canada’s CNSC Vendor Design Review – the first Generation IV reactor design to achieve this milestone.
