Skeleton has launched GrapheneUPS for AI data centres, a system intended to provide uninterrupted power protection while helping operators meet grid connection rules.
The launch comes as data centre operators face tighter grid stability requirements and growing scrutiny of the electrical impact of AI computing loads. Skeleton says the system is designed to address short-duration power disturbances and rapid load fluctuations without separate grid stabilisation equipment.
GrapheneUPS is a high-density uninterruptible power supply system based on the company's supercapacitor technology. According to Skeleton, it can increase computing power by 40% from existing power connections and reduce grid connection size by as much as 44%.
Unlike conventional UPS designs, the system is intended not only to isolate equipment from utility network disturbances but also to stabilise power during voltage dips, interruptions and grid restoration. Skeleton says this approach is aimed at helping data centres comply with connection standards as utilities tighten technical requirements.
Deployment options
According to Skeleton, GrapheneUPS can be installed in white space, gray space or outside a facility in a containerised format. The unit offers 50% lower volume for the same performance than competing systems, the company says.
It is designed to sit close to critical equipment as a no-break layer, alongside site-level battery energy storage systems used for longer-duration reserve and energy shifting. Skeleton says the product aligns with higher-voltage data centre roadmaps and can integrate across multiple DC voltage levels.
In one configuration, the system connects on the AC side with standard three-phase low-voltage distribution and supplies stabilised DC power to IT racks. This setup is intended to provide power smoothing as well as short-term backup.
Supply chain focus
Skeleton is also linking the launch to its manufacturing and supply chain strategy. It says it owns its value chain in Europe, is backed by Taiwan's largest fund and is expanding production to the US.
Skeleton says its supercapacitor technology does not use rare earth materials or conflict minerals and is not dependent on Chinese supply chains. That position reflects broader concern across technology infrastructure markets about access to critical materials and geopolitical exposure in strategic hardware supply.
The company says it is already supplying hyperscalers in the US and that millions of its supercapacitors are being used to support AI infrastructure at a large social network.
Grid pressure
The announcement highlights a growing challenge for operators of AI data centres, which are placing heavier and more variable demands on electricity networks. Grid operators in several markets have introduced stricter connection codes as they try to maintain stability while accommodating large new loads.
That has increased interest in equipment that can manage disturbances at the site level and reduce the burden on the wider network. UPS systems have long been central to data centre resilience, but suppliers are now also positioning them as tools for both uptime and grid compliance.
Skeleton says safety was central to the design, with the energy storage approach intended to avoid concerns associated with lithium-ion batteries, including thermal runaway. The company is presenting the system as part of a broader offering spanning data centre and grid power applications.
Tero Järveläinen, Chief Product Officer at Skeleton Technologies, said the system is designed to sit between unstable grid conditions and critical 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," he said.
