Siemens expands its data center portfolio, invests in Skeleton Technologies
- October 14, 2026
Siemens is expanding its data center portfolio through a strategic investment and exclusive partnership with Skeleton Technologies.
Skeleton Technologies is a developer and manufacturer of high-power energy storage systems, specializing in supercapacitors to manage transient power spikes and peak shaving solutions.
The partnership strengthens Siemens’ position in the fast-growing data centers space by adding high-performance supercapacitor technology to its electrical infrastructure portfolio.
As a leading technology company, Siemens supports customers across the entire data center ecosystem from the utility connection to the white space and is a trusted partner relied upon by nine of the top ten global data center providers, Siemens said in a release.
Siemens has been supporting Skeleton Technologies as a technology partner since 2022 and has also been involved as an investor since 2023. With this, Siemens is continuously strengthening its role in the AI infrastructure ecosystem.
The new offering addresses a central constraint on the expansion of data centers: massive, rapid and recurring swings in electricity demand. AI workloads synchronize thousands of powerful chips, whose power demand can rise or fall within milliseconds and aggregate into swings at megawatt scale in seconds.
Role of supercapacitors
Skeleton’s supercapacitors solve this industry challenge by acting as an electrical shock absorber, absorbing these rapid power swings, protecting valuable equipment and the grid while helping operators increase compute density and limiting the need for costly and time-consuming upgrades to existing facilities. The offering is aimed at the expansive ecosystem, building out hyperscale data centers and AI Factories.
It is designed to enable higher-density AI deployments, reduce utility-side power disturbances and accelerate the deployment of new capacity without a complete facility redesign. The solution can be deployed in existing AC architectures and retrofit projects, while providing a pathway toward future 800V DC standards.
Unlocking more AI capacity
“The race to scale AI is increasingly becoming a race for power. Data center operators need ways to expand capacity faster without waiting years for new grid and facility infrastructure. Our strategic investment into Skeleton addresses exactly this challenge. By combining Siemens’ electrical infrastructure expertise with Skeleton’s breakthrough supercapacitor technology, we can help customers unlock more AI capacity, improve resilience and accelerate growth in a rapidly expanding market,” said Peter Koerte, Member of the Managing Board of Siemens AG and President Smart Infrastructure.
