Utilidata—renamed Karman in September 2026—and NexGen Cloud are trying to make more of a data center’s existing electrical capacity usable by measuring and controlling power at the rack level. Their headline claim, up to 50% more capacity, is a company target or estimate, not a result independently verified at the Montreal deployment.
What did Utilidata and NexGen Cloud announce?
On March 12, 2026, Utilidata announced an agreement to deploy its Karman AI power-control platform across NexGen Cloud data centers, starting with a showcase site in Montreal. NexGen Cloud said it saw potential for a broader rollout across its European operations and planned to extend power-related capacity and services through its Hyperstack AI cloud platform. Those were plans, not confirmation that the rollout or customer benefits had been completed.
On September 17, 2026, Utilidata announced that it had rebranded as Karman and said the first commercial deployment with NexGen Cloud was operating in an Enovum data center in Montreal. The announcement establishes that operating site; it does not establish that the planned European rollout is complete.
What does “stranded AI power” mean here?
In this context, “stranded power” means electrical capacity that is already provisioned for a data center but is not fully used for computing. Operators may leave headroom as a safety margin because IT loads can change quickly and power must remain within equipment and facility limits. Better monitoring and control could, in principle, let an operator use more of that headroom without exceeding those limits.

This is an effort to orchestrate electricity inside a data center—not a new electricity supply. It does not create power or remove the need for grid connections, utility capacity, or investment in electrical infrastructure.
How is Karman supposed to work?
Measure power at the rack
Karman is described as an embedded system for data-center power infrastructure, combining high-resolution power measurement with local processing and AI. Rack-level measurements are intended to give the system a more immediate view of changing electrical conditions than a slower, facility-level response alone.

Advanced BMS provides 12 safety protections, monitoring voltage, current & temperature. Powers your smartphone, laptop, mini-fridge, camera, and drone simultaneously.
Respond to changing loads
Utilidata’s March 2026 announcement says Karman samples at more than 1 million times per second and has sub-20-millisecond latency. Those are company-stated specifications, not independently tested performance figures. The stated purpose is to respond quickly enough to help operators manage power delivery as computing loads vary, while maintaining reliability safeguards.
The company says Karman runs on a custom NVIDIA module. That does not mean a retail NVIDIA developer kit is equivalent to the deployed system: the module is only one part of an integrated power-monitoring and control platform.

What is confirmed, and what remains a target?
| Item | What the sources establish | Qualification |
|---|---|---|
| Montreal deployment | Karman and NexGen Cloud reported the first commercial deployment operating at an Enovum data center in Montreal on September 17, 2026. | This establishes the reported operating site, not performance results or a wider rollout. |
| Up to 50% more usable capacity | Utilidata and NexGen Cloud described this as a potential increase or target; Karman’s data-center page calls it an estimate. | Results may vary by customer environment and server configuration. The reviewed sources provide no independently measured before-and-after result for Montreal. |
| Broader European rollout | NexGen Cloud described a potential expansion across European operations in March 2026. | The reviewed material does not confirm that expansion has been completed. |
For context, Utilidata CEO Josh Brumberger called power “the single biggest constraint for AI growth today” in the March partnership announcement. That is his framing of the problem, not an independently verified measure of how much capacity is underused across data centers.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.What should a data-center operator look for?
The relevant test is not simply whether a control system samples quickly or whether a vendor advertises a capacity increase. An operator assessing a deployment would need to know how much additional computing can be supported on the same provisioned power, what safeguards constrain control actions, how the system integrates with the facility, and how long deployment takes. Independently reported operating results would also help distinguish an estimate from demonstrated performance.

The sources reviewed describe Karman’s intended approach and the Montreal operating site, but do not provide a head-to-head comparison with another vendor or independently validated results. The up-to-50% figure should therefore be read as an estimate or goal, not as a guaranteed gain for a facility or a measured outcome from the Montreal installation.
