Ameresco and U.S. Navy Partner to Build AI-Optimized Data Center and Energy Infrastructure at NAS Lemoore

In accordance with the Administration’s AI Action Plan and Executive Orders on Accelerating Federal Permitting of Data Center Infrastructure, Removing Barriers to American Leadership in Artificial Intelligence and Unleashing American Energy, this public-private partnership delivers power and data center capabilities that enable secure, on-premises AI compute environments optimized for sensitive government and enterprise applications, including large language model training, real-time analytics and mission-critical decision systems.

“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.”

“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,” said Nicole Bulgarino, President, Federal Solutions & Utility Infrastructure at Ameresco. “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.”

Ameresco has partnered with CyrusOne to deliver mission-ready AI data center infrastructure, in part based on the capabilities of its Intelliscale™ platform. Intelliscale™ is purpose-built for artificial intelligence and high-density computing, enabling agencies to meet the growing demands of defense, intelligence, and national security operations. The facility will be engineered to meet stringent federal security and compliance standards, including FedRAMP, FISMA High, and DoD Impact Levels 5 and 6, and will align with NIST cybersecurity frameworks. For the most sensitive workloads, it will feature air-gapped architectures, cross-domain solutions, and zero-trust security models to ensure data integrity and mission assurance across both classified and unclassified environments. Across all workloads, the data center is engineered to handle the extreme computational intensity of advanced processors optimized for parallel processing, model training, accelerated inference and real-time analytics. Collectively, these capabilities empower agencies to advance next generation applications in defense, intelligence analysis, cyber security and decision support.

“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,” said John Hatem, Executive Vice President and Chief Operating Officer of CyrusOne. “Data centers are foundational to our information economy and critical to maintaining U.S. leadership in technological innovation, especially in AI. We’re proud to deliver this solution through our alliance with Ameresco.”

The collaboration between Ameresco and CyrusOne combines the two organizations’ decades of experience in the development of energy solutions, data centers, and critical infrastructure, as well as both companies supporting government agencies across military, energy, and defense.

The first portion of the project is expected to come online in 2027 and will be constructed on land leased by Ameresco from the Department of Defense.

This initiative marks a new era of secure, AI-powered infrastructure for federal missions – one that could serve as a model for future deployments across the Department of Defense and beyond.
