MIAMI--(BUSINESS WIRE)--ON.energy today announced it has completed construction of its AI UPS™, the first medium-voltage uninterruptible power system engineered for large-scale AI data centers, at the National Laboratory of the Rockies (NLR). Together, ON.energy and NLR will test the technology at NLR’s Flatirons Campus near Boulder, Colorado, home to one of the world’s most advanced grid simulators and the Advanced Research on Integrated Energy Systems (ARIES) research platform.

As AI campuses scale toward gigawatt footprints, data center operators are confronting steep GPU power transients, rapid load swings, and rising expectations for voltage ride-through performance. Customers across the sector are searching for solutions as conventional UPS electrical architectures are unable to meet the requirements seen in today’s AI compute environments. ON.energy’s deployment with NLR is designed to answer that need.


Under the agreement, NLR will simulate both the power profile of an AI data center, including fast-moving GPU workload spikes, and a full range of grid and off-grid operating conditions. The testing will validate how ON.energy’s AI UPS stabilizes these loads, protects the data center, and supports the electric grid during disturbance events.
