Nvidia and homebuilder PulteGroup are working with Span, a California-based startup, to test small “fractional” data centers installed on the exterior of newly built homes.
The system uses Span’s smart electrical panels to identify unused local grid capacity and route that power to compact nodes, known as XFRA units, that can be networked together to provide AI computing capacity.
Span says the XFRA units use liquid-cooled Nvidia RTX PRO 6000 Blackwell Server Edition GPUs. The company’s concept is that a distributed network of these nodes could function like a small to mid-sized traditional data center, either augmenting existing facilities or reducing the need for new large-scale builds.
The pilot is in an early testing phase in a handful of PulteGroup communities, according to the companies.
Span estimates it can install 8,000 XFRA units about six times faster and at five times lower cost than building a centralized 100-megawatt data center of comparable capacity.
For homeowners who host an XFRA node, Span expects compensation to come in the form of heavily discounted energy and internet costs, creating an incentive to participate as AI-driven power demand increases pressure on local grids.
