Ameresco has announced plans with the US Navy and CyrusOne to develop a 100 megawatt (MW) data center designed for advanced artificial intelligence (AI) workloads at Naval Air Station (NAS) Lemoore in California. The project will include dedicated onsite energy generation and a microgrid, aiming to provide secure, reliable infrastructure for both the data center and base operations.
The planned facility will include a microgrid with engine generators, upgraded control systems, and power infrastructure improvements to support NAS Lemoore’s energy needs. According to Ameresco, the data center is engineered specifically for AI and high-density computing, leveraging CyrusOne’s Intelliscale platform. Technical requirements addressed in the announcement include support for workloads such as large language model training, real-time analytics, and mission-critical decision systems. The design will allow for parallel processing, model training, accelerated inference, and high-intensity computation—all suited for advanced AI processors.
The installation is expected to comply with strict federal security and compliance standards, including the Federal Risk and Authorization Management Program (FedRAMP), Federal Information Security Management Act (FISMA) High, and Department of Defense (DoD) Impact Levels 5 and 6. Ameresco notes solutions for both classified and unclassified environments, such as air-gapped architectures, cross-domain solutions, and zero-trust security models. These features are intended to support sensitive federal workloads in defense, intelligence, and cybersecurity applications.
NAS Lemoore Executive Officer Captain Jeffry Findlay stated, “This initiative directly supports our national priorities in AI and energy dominance,” said NAS Lemoore Executive Officer Captain Jeffry Findlay. “By enabling secure, reliable power and compute infrastructure at NAS Lemoore, we’re strengthening our ability to support critical missions and ensure operational continuity for those who serve.”
Nicole Bulgarino, President of Federal Solutions and Utility Infrastructure at Ameresco, said, “Ameresco is proud to develop energy infrastructure at NAS Lemoore that directly supports the growing demand for AI-ready data centers and related energy infrastructure.” Bulgarino added, “We look forward to working with the Navy and CyrusOne to develop this critical infrastructure that supports energy resiliency for the installation and meets the unique energy and reliability requirements of advanced AI data center workloads.”
John Hatem, Executive Vice President and Chief Operating Officer of CyrusOne, noted, “The facility at NAS Lemoore will provide our federal customers with the secure, on-premise computing solution they need—paired with the resilience of onsite energy supply.”
The project is scheduled to begin phased operations in 2027, pending finalization of development agreements. Ameresco will lease the land from the Department of Defense, and both companies highlight this as one of Ameresco’s largest energy asset developments to date.
