Next-Generation Nuclear Energy with SMRs and MMRs
Ameresco is at the forefront of advancing next-generation nuclear energy by deploying Small Modular Reactors (SMRs) and Micro Modular Reactors (MMRs). These innovative technologies are designed to deliver reliable, emissions-free power to customers with the most demanding energy needs. They are designed to provide a continuous supply of carbon-free electricity that enhances energy security, supports grid reliability, and enables significant decarbonization across energy-intensive and mission- critical applications. Ameresco deploys nuclear solutions ranging from 1 MW to GW+ scale, depending on project requirements.
In alignment with Federal priorities focused on supporting data center expansion, artificial intelligence (AI) development, and modernization of critical infrastructure, SMRs and MMRs provide firm power exactly where reliability is essential. These solutions are reinforcing Ameresco’s commitment to supporting the evolving needs of advanced infrastructure.
A Strategic Addition to Ameresco’s Energy Supply Portfolio
SMRs and MMRs complement Ameresco’s diversified generation and energy supply solutions, including solar, battery energy storage systems (BESS), combined heat and power (CHP), geothermal, and renewable natural gas (RNG). Together, these technologies enable integrated, resilient energy systems designed to meet long-term operational, sustainability, and security goals.

Ameresco applies its technology-agnostic approach to nuclear energy, leveraging strategic partnerships with a select group of SMR and MMR providers such as Terrestrial Energy, Terra Innovatum, and Nano Nuclear Energy, to accelerate the deployment of scalable, next-generation solutions. This flexible, objective strategy enables Ameresco to tailor advanced nuclear technologies to the unique requirements of each customer and integrate them efficiently into resilient energy systems.
Modular Nuclear Power, Reimagined
SMRs and MMRs are designed to deliver clean, continuous, and predictable energy with reduced capital risk.
SMRs are factory manufactured and assembled onsite, enabling controlled production, shorter construction timelines, and scalable deployment. SMRs are well suited for customers seeking firm, low carbon power at scale, particularly in regions facing grid constraints or aggressive emissions reduction targets.
MMRs take modularity further, utilizing simplified designs with minimal moving parts. These systems require limited onsite construction and support remote or autonomous operation, making them ideal for defense installations, remote locations, and other critical facilities requiring secure, 24/7 power.
Powering Critical Infrastructure
SMRs and MMRs provide resilient, around-the-clock energy for applications where downtime is not an option, including data centers, Federal and defense facilities, remote sites, and other mission-critical infrastructure. By combining advanced nuclear technology with Ameresco’s proven energy delivery expertise, these solutions support:
- Firm, 24/7 Power Supply – Continuous, nonintermittent energy that supports mission continuity
- Carbon-Free Generation – Zero-emissions electricity to advance decarbonization goals
- Enhanced Energy Security – Onsite or distributed generation reduces reliance on the grid
- High Reliability and Resilience – Designed for critical infrastructure and demanding environments
- Scalable and Modular Deployment – Capacity can be added incrementally to meet evolving needs
