Homeowners in a planned 100-home pilot with homebuilder PulteGroup are being offered a deal that sounds made up: a mini data center mounted on the home, installed during construction at no cost to them, and electricity and internet at a flat, heavily discounted rate — an example figure of about $150 a month covering both. The hardware belongs to SPAN, the smart-panel company behind the XFRA program, launched with NVIDIA as its initial partner. SPAN sells the computing power; the home supplies the wall, the power connection and a place in the neighborhood. The first program was announced by SPAN in May 2026, and the newest step came on September 23, 2026, when Sunrun signed on as an installation partner.
What happened
SPAN, best known for smart electrical panels that manage home energy, announced XFRA as a "distributed data center": instead of one giant facility, computing nodes are installed in homes and small commercial spaces and coordinated as a single system. NVIDIA is the launch partner, and the nodes are built around its liquid-cooled RTX PRO 6000 Blackwell Server Edition GPUs. PulteGroup, one of the largest US homebuilders, is assisting the rollout, with a 100-home proof of concept planned for the third quarter of 2026; reports name Nevada and Arizona among the pilot states. A small number of early installations were reported ahead of that proof of concept.
In September 2026 the program added Sunrun, the residential solar installer, as a partner: according to Solar Power World, Sunrun will install the systems, and hosts receive solar panels and multi-battery storage under a pre-paid lease at no cost, whole-home battery backup, and ongoing compensation linked to the energy their system manages.
How a wall becomes a data center
Each XFRA node is serious hardware. Reporting by Data Center Dynamics puts a node at 16 NVIDIA RTX Pro 6000 Blackwell GPUs alongside 4 AMD EPYC server CPUs, liquid-cooled and coordinated through SPAN's XFRA Cloud software, which manages the fleet of nodes as one distributed machine. Technology press coverage has put the hardware value of a node at more than $250,000, though SPAN has not published a per-node price. The node is tied into the home through a premium SPAN smart panel, with battery backup and optional solar.
The pitch is aimed at AI inference — the work of running AI models for users, rather than training them. Inference needs to be near the people using it, because distance adds delay, and it needs power, which is exactly what new centralized data centers are struggling to secure quickly. SPAN's position, stated in its announcement, is that XFRA is "not intended to replace centralized data centers, but augment them."
What the homeowner gets
The homeowner side of the deal is unusually simple. The node is installed during construction at no cost to the homeowner, and SPAN owns and operates the hardware. In exchange for hosting it, the home receives fixed, discounted electricity and internet rates. SPAN's chief executive, Arch Rao, gave CNBC an example flat fee of $150 a month covering both electricity and internet — about half of what he said the average American household pays, and in some cases, he said, there could be no fee at all; the example was reported by CNBC and retold by Realtor.com. Some reports say hosts also keep a share of the revenue from the compute sold from their node, though the proportion has not been disclosed.
With the Sunrun arrangement, hosts additionally get rooftop solar and battery storage at no upfront cost, with the batteries doubling as whole-home backup power. SPAN's broader pitch to homeowners and builders is that a home wired this way is cheaper to run and more resilient — the data center is, in effect, subsidizing the home's energy system.
Why NVIDIA and SPAN are doing this
The bottleneck for AI computing has shifted from chips to electricity and time. A conventional data center can take years to build and connect to the grid; a neighborhood of homes is already connected. SPAN argues that distributed nodes can be deployed far faster — it cites figures in its launch coverage suggesting deployments roughly six times faster and at about a fifth of the cost of centralized capacity, and claims that a fleet of around 8,000 home nodes would add up to roughly a 100-megawatt data center. Those are SPAN's own estimates, not independently verified figures, but they explain the strategy: NVIDIA's Marc Spieler told CNBC the industry focus is shifting from building bigger facilities to getting more out of existing infrastructure.
There is a public-opinion angle too. Polling by Redfin and Ipsos cited in coverage by Bisnow found 47% of Americans oppose a data center in their neighborhood. A program that hides the data center inside new homes — and pays the hosts in cheap power — is, at least in part, an answer to that resistance. Whether neighbors who did not sign up feel the same way is an open question the pilot will test.
What to watch next
Three things will decide whether XFRA is a curiosity or a category. First, the 100-home PulteGroup proof of concept: do the nodes run reliably through a summer of household life? Second, the real economics for hosts once bills arrive — whether the $150 example becomes a standard offer, and whether any revenue share is meaningful. Third, the regulatory and neighborhood response in the pilot states, ahead of SPAN's stated ambition of a gigawatt-scale pipeline by 2027. If those three break its way, "the house comes with a data center" may become a line in new-build listings — and a new front in the race for AI power.
Frequently Asked Questions
Do homeowners have to buy the mini data center?
No. In SPAN's XFRA program the node is installed during construction at no cost to the homeowner, and SPAN owns and operates the hardware.
What do hosts actually get?
Fixed, discounted electricity and internet — SPAN's CEO gave an example flat fee of about $150 a month for both — plus, under the September 2026 Sunrun partnership, solar and battery storage at no upfront cost and whole-home backup power. Some reports mention a share of compute revenue, in an undisclosed proportion.
Where is this happening?
The announced proof of concept covers about 100 homes with homebuilder PulteGroup, planned for the third quarter of 2026, with reports naming Nevada and Arizona. A small number of early installations were reported before it.
