Grid-edge energy company Span has launched XFRA, a distributed data center solution. Comprising a distributed network of compute nodes located in residential and small commercial spaces, XFRA enables both the immediate and future compute needs of hyperscalers, neoscalers and AI cloud providers.
Initial launch partners include AI chip maker NVIDIA. This solution will launch with enterprise grade, liquid-cooled NVIDIA RTX PRO 6000 Blackwell Server Edition GPUs.

“Span’s unique and differentiated intellectual property in power controls enables us to improve the utilization of existing grid infrastructure,” said Arch Rao, founder and CEO of Span. “We have successfully deployed this capability to accelerate home electrification, unlock new home construction, and increase utility grid utilization. Now, distributed compute is the next logical extension of our technology. By building on our core strengths in power optimization and collaborating with industry leaders like NVIDIA, we are collapsing the speed-to-power gap to deliver gigawatts of cost-effective compute capacity at unprecedented speed.”
AI has transformed global energy demand. In 2024, U.S. data centers consumed 183 terawatt-hours (TWh) of electricity, totaling more than 4% of America’s total electricity consumption, and experts predict it may exceed 9% by 2030. The grid infrastructure needed to support this scale can take years to build, and some projects have already been delayed and are waiting for interconnection approval. By utilizing existing grid capacity, XFRA can quickly and efficiently meet industry needs for increased compute capacity.
“As the demand for AI and inference compute continues to accelerate, there is a critical need for low-latency solutions that are proximal to end users and can scale rapidly,” said Marc Spieler, Senior Managing Director of Global Energy Industry at NVIDIA. “Span is pioneering new ways to deploy enterprise-grade GPUs in distributed environments. The XFRA solution helps meet the specific power and latency requirements of modern inference workloads while making compute more accessible and efficient.”
XFRA leverages the Span smart electrical panel’s core built-in intelligence: integrated energy management and power controls functionality that unlock additional electrical service capacity (headroom) in the existing grid. This capacity powers high-performance compute nodes for AI inference, cloud gaming and other AI workloads. As these demands rapidly increase, offtakers need a low-cost, low-latency solution that can scale quickly. XFRA is not intended to replace centralized data centers, but instead augment them by accelerating capacity growth at the grid edge. XFRA uniquely leverages underutilized power infrastructure in close proximity to end-users’ demand for inference compute, creating a system-wide win-win.
Homeowners will have a XFRA unit installed outdoors, and it is designed to be self-contained, quiet, modular, serviceable and secure. A typical home has a 200-A electrical panel while only consuming less than 100 A. XFRA will take that underutilized capacity from multiple homes, and act like a power cloud to coordinate capacity at a gigawatt-scale.
Span is working with homebuilders like PulteGroup to accelerate the initial rollout of XFRA on-site. Participating homeowners will receive a Span Panel, battery backup and optional solar plus fixed, discounted rates for electricity and internet.
With initial deployments beginning later this year, Span has developed a pipeline of deployment capacity to achieve gigawatt-scale in 2027, enabled by XFRA’s highly distributed structure and low-friction scaling requirements.
