Hyperscale Meets Grid Stability: ON.energy Launches Medium-Voltage UPS Built for AI Data Centers

• Traditional UPS systems weren’t built for the fast ramp rates and voltage transients of AI workloads, putting both uptime and grid stability at risk.
• Acting as a dynamic power layer between grid and compute, the ON.energy system’s medium-voltage, grid-interactive design shields campuses from power volatility and delivers grid-safe resilience.
• ON.energy’s AI UPS sets a new benchmark for how next-generation compute infrastructure connects to the grid.

AI data centers have become the largest single power loads on earth. Multi-hundred-megawatt campuses and high load factors are stretching utility systems faster than interconnection processes can evolve. Traditional UPS designs were never intended to handle the rapid ramp rates, voltage transients, and disturbance sensitivity of AI workloads, creating a growing risk to both uptime and grid stability.

ON.energy’s AI UPS sits between the grid and the data center as a dynamic power layer that ensures reliable, grid-safe data center architecture. Its proprietary system architecture scales seamlessly from megawatts to gigawatts in both grid-connected and off-grid environments, safeguarding the grid and on-site generation by absorbing AI transients and load fluctuations while delivering industry-leading voltage and frequency ride-through performance that accelerates interconnection timing.

“The global race to build AI training capacity may be the most important infrastructure challenge of our time. Managing the massive, volatile load profiles of GPU clusters without risking grid stability is the bottleneck that defines how quickly these facilities can come online," said Alan Cooper, Co-Founder and CEO of ON.energy. “AI UPS is the new standard for how to interconnect AI data centers to the grid—faster, safer, and more resilient.”

Unlike conventional UPS systems, AI UPS is grid-interactive, transforming what was once a sunk cost into a revenue-generating asset. Data center owners can leverage ON.energy’s medium-voltage UPS in energy markets or behind-the-meter energy savings programs, generating millions of dollars of revenue annually per 100 MW of IT load.

“We engineered AI UPS to set a clear technical standard for what grid-safe data center interconnection looks like,” said Ricardo de Azevedo, Co-Founder and CTO of ON.energy. “It’s a scalable foundation for the next era of AI infrastructure, one that protects both the data center and the grid.”

ON.energy’s AI UPS is now being deployed across multiple U.S. hyperscale campuses, supporting the rapid expansion of AI infrastructure with resilient, grid-safe power systems built for scale.
