Yes in my backyard

Free power, cooling, heating, and internet: What's the catch?

The flyer arrived on a Tuesday in late spring, tucked under the doormat of a modest suburban house outside Phoenix. It was from a company called LocalGrid Energy. The pitch was simple and bold: they would install the maximum reasonable number of solar panels on your roof, garage, siding, and fences. They would also place a weatherproof shed in the backyard roughly the size of a large storage unit. Inside that shed would sit batteries plus a compact server cluster. In exchange, the homeowner or business owner would receive free electricity, free heating, free cooling, and free high-speed internet for as long as the agreement lasted, typically twenty years.

Marcus, a software engineer who worked from home, read the fine print twice. The panels would cover every suitable surface that local codes and structural engineers allowed. On his property that meant the south-facing roof, the garage roof, vertical bifacial panels along the fence lines where they would not block neighbors, and thin modules on the less-shaded sections of siding. The total system came in at about 28 kilowatts. Real-world installed residential solar costs in 2024 and 2025 hovered around $2.50 to $3.25 per watt before incentives. At roughly $2.75 per watt the hardware and labor would run near $77,000. The federal Investment Tax Credit of 30 percent brought the effective cost closer to $54,000. In Arizona the system was projected to generate around 1,500 to 1,700 kilowatt-hours per kilowatt each year, or roughly 42,000 to 47,000 kilowatt-hours annually.

The shed held a 60-kilowatt-hour battery bank and a modest edge server cluster. Lithium-ion pack prices had fallen to about $115 per kilowatt-hour in 2024, though fully installed residential or small commercial systems ran higher, often $200 to $300 per kilowatt-hour once inverters, enclosures, and labor were included. The battery portion alone might cost the company $12,000 to $18,000. The servers were not hyperscale AI machines. They were storage-heavy nodes optimized for caching the most requested video streams, game patches, software updates, and popular large files. A micro edge rack or two, drawing a steady 3 to 6 kilowatts including cooling, was realistic. Hardware and networking for such a node often landed between $25,000 and $60,000 depending on storage capacity and redundancy.

Mounted on the shed roof was a compact phased-array satellite antenna, similar in design to the consumer terminals used by low-Earth-orbit constellations. This downlink fed fresh content directly into the local cache at high speed whenever popular files needed updating, independent of terrestrial fiber congestion. LocalGrid owned everything. Marcus signed a long-term easement and access agreement. Crews arrived within weeks. Panels went up in orderly rows. The shed was delivered on a flatbed, connected to the home’s electrical panel, and linked both to the satellite terminal and to a local wireless mesh that blanketed the property. Waste heat from the servers was captured and routed through a heat-exchange system that could warm the house in winter. In summer the same efficient heat pumps and free cooling loops that kept the servers at safe temperatures also conditioned the living spaces. Marcus’s previous annual electricity bill had averaged about $1,900 at roughly 16.5 cents per kilowatt-hour for a typical 10,500 to 11,000 kilowatt-hour household. Heating and cooling often accounted for 40 to 50 percent of residential energy use; the combined value of free power, conditioned air, and unlimited high-speed internet easily exceeded $3,500 to $4,500 a year in a hot climate with typical broadband rates.

The real surprise came with the network. Because the shed held local copies of the latest high-demand content refreshed through the satellite downlink, Marcus noticed that 4K streams, multiplayer game downloads, and large software updates often began almost instantly. Latency dropped. Peak-hour buffering vanished. Neighbors within range of the mesh experienced the same improvement because LocalGrid’s distributed nodes shared popular files across a regional network. Content providers and connectivity partners paid LocalGrid for the reduced long-haul bandwidth and the improved user experience. Edge caching of repeated large files is precisely the kind of workload that benefits from physical proximity and a dedicated high-capacity feed.

On paper the economics could close. LocalGrid’s capital outlay per site might total $100,000 to $145,000 before incentives and volume discounts, including the satellite terminal hardware. Over twenty years the avoided retail electricity, HVAC, and internet costs for the homeowner represented substantial value. Excess solar generation after serving the house and the modest server load could be sold back under net-metering or wholesale arrangements. In sunny, high-rate markets the power alone helped. The larger revenue stream came from the distributed compute and storage network: content-delivery fees, reduced transit costs, and eventual rentals of spare capacity for low-latency services. Scale mattered. A few thousand such backyard nodes created a resilient edge layer that traditional centralized data centers could not match for local delivery.

Marcus’s first summer under the agreement felt almost surreal. The thermostat stayed comfortable without a single utility bill. His devices connected automatically to the free high-speed service powered by the backyard node. The roof and fences glinted with panels. The shed hummed quietly behind the garage, its satellite antenna tracking the sky. When he launched a newly released game or started a high-resolution documentary, the data often felt as if it already lived on his own machine. LocalGrid technicians visited twice a year for maintenance. Everything else ran itself.

Whether the model spreads beyond sunny regions with cooperative utilities and dense enough demand for cached content remains an open question. Battery and solar prices continue to fall. Server efficiency improves. Satellite capacity and user expectations for instant media keep rising. For Marcus the arrangement simply worked. He had said yes to the backyard, and the backyard now quietly powered his house, cooled his rooms, delivered free internet, and brought a faster slice of the online world a few dozen feet from his living room.
