Skeleton Technologies, a global AI infrastructure and grid power systems provider, today announced the launch of its GrapheneUPS, a high-density UPS system designed for AI data centers. The system delivers continuous power protection while enabling compliance with increasingly stringent data center grid connection requirements.
As grid operators tighten connection codes, data center deployments face increasing challenges in meeting grid stability requirements. GrapheneUPS addresses these challenges by enabling reliable compliance with grid connection standards.
Unlike conventional UPS architectures, double-conversion systems continuously convert incoming AC power to DC and back to AC, isolating critical AI equipment from utility disturbances. GrapheneUPS builds on this by actively stabilizing grid power, mitigating fluctuations during events such as voltage dips, interruptions, and grid restoration. This enables compliance with grid code requirements without additional stabilization equipment.
The system enables a 40% increase in computing power and up to a 44% smaller grid connection, confirming the company’s role as the only full provider of AI infrastructure power systems from data centers to the grid. By stabilizing short-duration disturbances and managing rapid load fluctuations, GrapheneUPS helps reduce downtime risk, protect sensitive equipment, and optimize power delivery for increasingly dynamic AI workloads.
"As grids become increasingly volatile and prone to disturbances, Skeleton’s approach is to support grid infrastructure and to ensure that data center operations remain stable and protected through interruptions. GrapheneUPS acts as a resilience layer that secures continuous operation during grid incidents, shielding critical AI workloads from instability,” said Tero Järveläinen, Chief Product Officer at Skeleton Technologies.
The GrapheneUPS system can be deployed in data center white space, gray space, or outside the facility as a containerized solution, delivering 50% lower volume for the same performance compared to competitors. The system is designed to operate as a load-proximate no-break layer near critical equipment, complementing site-level battery energy storage systems optimized for longer-duration campus energy reserve and energy shifting.
The system is aligned with evolving high-voltage data center roadmaps and supports integration across multiple DC voltage levels, with readiness for future higher-voltage standards. In an AC-connected sidecar configuration, GrapheneUPS integrates with standard three-phase low-voltage distribution to deliver stabilized DC power to IT racks, providing power smoothing and short-term backup capability.
Safety and resilience are core design priorities. Skeleton highlights an inherently safe energy storage approach intended to mitigate key safety concerns associated with lithium-ion systems, including thermal runaway.
