Terra Innovatum and Ameresco Partner to Deploy 50 Micro-Modular Nuclear Reactors

Terra Innovatum Srl, a developer of micro-modular nuclear reactors, and Ameresco, a leading energy solutions provider, have signed a memorandum of understanding to establish a comprehensive framework for deploying SOLO micro-modular reactors across U.S. and international markets. The partnership creates a strategic pathway for evaluating siting, development, construction, integration, operation, and decommissioning planning for the innovative nuclear technology.

The collaboration will leverage Ameresco's national network and expertise to identify siting opportunities on public and private land, with a goal to secure deployment of 50 reactor units across federal and commercial sites. This represents a major step toward near-term commercial rollout of the SOLO reactor technology, which is designed to provide scalable, affordable nuclear power solutions.

Alessandro Petruzzi, CEO of Terra Innovatum, emphasized the significance of the partnership, stating that Ameresco's deep industry network and expertise in delivering innovative energy solutions will play a crucial role in SOLO's commercial deployment. The collaboration provides Terra Innovatum with expanded reach and accelerated market access through Ameresco's established presence in energy infrastructure development.

Giordano Morichi, Partner and Chief Business Development Officer at Terra Innovatum, highlighted the multi-tiered approach enabled by the partnership. The agreement allows for parallel deployment strategies while pursuing both U.S. government and private sector opportunities, advancing the commercialization of 50 SOLO reactor units to address critical energy security needs domestically and internationally.

Nicole Bulgarino, President of Federal Solutions and Utility Infrastructure at Ameresco, noted that the company brings decades of experience in delivering advanced energy solutions across federal and commercial markets. The partnership aligns with Ameresco's focus on providing resilient energy infrastructure to support mission readiness and energy assurance in an evolving global landscape.

The SOLO micro-modular reactor represents a significant innovation in nuclear technology, designed to deliver 1 MWe of power using commercial off-the-shelf components that enable rapid deployment and minimize supply chain risks. The technology supports both Low Enriched Uranium Plus and High Assay Low Enriched Uranium fuels, offering flexibility for future fuel transitions while ensuring cost predictability.

SOLO's applications extend beyond electricity generation to include heat production for industrial processes, water treatment, desalination, and co-generation. The technology also has potential medical applications, producing radioisotopes essential for oncology research and cancer treatment. With its modular design, SOLO can scale to deliver up to 1GW or more of CO2-free power with minimal footprint, making it suitable for replacing fossil fuel-based thermal plants.

Anticipated to be available globally within the next three years, SOLO addresses pressing global energy demands with a market-ready solution developed over six years by experts in nuclear safety, licensing, innovation, and research and development. The partnership between Terra Innovatum and Ameresco creates a powerful combination of innovative nuclear technology and established energy infrastructure expertise, positioning both companies to capitalize on growing demand for reliable, carbon-free power solutions.
