ON.energy Deploys Medium Voltage AI UPS for Grid-Safe AI Campuses at National Laboratory of the Rockies

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.

The ON.energy installation at Flatirons also provides a controlled platform for customers to run their own validation scenarios, a capability already attracting interest from a number of hyperscalers.

“Customers want to see how a medium-voltage UPS between grid and compute behaves under real grid disturbances and load volatility for their unique GPU-profile,” said Dax Kepshire, President of ON.energy’s Data Center division. “Our deployment at NLR’s Flatirons Campus lets us provide extensive performance validation of our AI UPS meeting each customer’s unique requirements in a controlled environment.”

“NLR is committed to advancing technologies that improve the flexibility and reliability of the nation’s power systems and at the speed this sector demands,” said Andrew Hudgins, ARIES Laboratory Program Manager. “With ON.energy the teams have gone from first contact through contracting and construction in less than six months here at Flatirons Campus.”

For ON.energy, this marks a significant milestone in demonstrating the capabilities of AI UPS as the backbone of grid-safe AI campuses. As demand for compute accelerates, the ability to manage GPU transients, maintain ride-through, and reduce stress on the grid is becoming a defining factor for next-generation AI campuses.
