On September 29, 2025, Ameresco (NYSE: AMRC) announced that it had signed a memorandum of understanding with Terra Innovatum Srl, a developer of micro‑modular nuclear reactors, to establish a comprehensive framework for siting, developing, constructing, integrating, operating and decommissioning the company’s SOLO™ reactor technology. The partnership aims to deploy 50 SOLO reactors across federal and commercial sites, including locations in New York and Austin, Texas.
Ameresco will leverage its extensive U.S. network and expertise in delivering advanced energy solutions to identify and secure suitable sites for the reactors. The company’s experience in federal and commercial projects positions it to facilitate the integration of the SOLO reactors into existing infrastructure, potentially accelerating deployment timelines and reducing project risk.
Terra Innovatum’s SOLO reactor is a 1 MWe micro‑modular design that can be scaled to deliver up to 1 GW of CO₂‑free power. The technology is built from commercial off‑the‑shelf components, offers rapid deployment, and supports a range of applications from data centers to industrial heat. The MOU therefore introduces a new, high‑margin revenue stream for Ameresco and expands its service offering into the growing small‑modular reactor market.
The collaboration represents a strategic expansion for Ameresco, aligning with its broader goal of diversifying into next‑generation firm energy solutions. By partnering with a leading SMR developer, Ameresco can tap into a new customer base, enhance its portfolio of resilient power options, and position itself as a key player in the emerging nuclear market.
