Ameresco, Inc. has teamed up with the U.S. Navy and CyrusOne to develop a massive new project at Naval Air Station (NAS) Lemoore in California — a 100-megawatt AI-optimized data center paired with its own dedicated energy infrastructure.
The state-of-the-art facility will not only support future-looking artificial intelligence workloads, but also increase the base’s energy resiliency. A new microgrid with generators, control systems, and infrastructure upgrades to provide reliable power for Navy operations is on the plan list. Ameresco says the project would represent one of its largest energy assets to date.
The project aligns with the federal government’s initiative to accelerate data center infrastructure and enhance America’s leadership position in both energy and AI. The facility is being created for heavily classified government and defense purposes, including from training large AI models to mission-critical decision systems and real-time analytics.
Captain Jeffry Findlay, Executive Officer at NAS Lemoore, said the project will directly support national priorities. “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,” he noted.
Built to Federal Security and Compliance Standards
Ameresco will work with CyrusOne to deliver the data center, which will include CyrusOne’s Intelliscale™ platform — purpose-built for AI and high-density computing. The data center will meet high-level federal security and compliance standards. And integrate robust protections such as air-gapped systems, cross-domain solutions, and zero-trust security models.
John Hatem, Chief Operating Officer of CyrusOne, stated that secure and reliable data centers are the basis for the United States’ leadership in AI. “The NAS Lemoore data center will provide our federal customers with the secure, on-premise compute solution they need—along with the availability of on-site power,” he stated.
Construction is set to begin shortly, with the first phase coming on line in 2027. The project will be built on Department of Defense leased property and could serve as a model for future Department of Defense deployments.
The NAS Lemoore project is part of a series of national projects aimed at retaining a competitive advantage within the global competition for AI dominance. Governments and the private sector worldwide are investing heavily in high-end computing infrastructure. But the leaders of America think secure, AI-enabled data centers are the way to maintain technological and military dominance. By combining energy resiliency with cutting-edge computing power, the Ameresco–Navy–CyrusOne initiative showcases how the United States is working towards setting the best practices for innovation, security, and operating readiness in the age of AI.
