Rooftop solar & prosumer energy markets
A farmer with a 5 kW rooftop array generates far more at noon than the household uses, and the local utility pays a thin feed-in rate for the surplus. Next door, a cold-storage owner is buying expensive daytime grid power. They can't trade with each other — the meter, the utility portal, and the settlement rails all assume one seller (the utility) and many passive consumers.
Fabric turns rooftops, EV fleets, and flexible industrial loads into addressable participants in a real-time energy market — able to discover each other, contract under network policy, and settle instantly against metered delivery.
What changes
A prosumer sells surplus daytime solar to a neighbour or nearby business at a better price than the net-metering rate — improving ROI in exactly the hours their own use is lowest.
Net-metering credits become portable across a participant's sites (one site → another site's bill) because entitlement is a credential, not a hard-wired meter address.
A rooftop-solar EPC can stitch lead → survey → grid approval → rebate → payout into one journey, because each step is a signed, discoverable action instead of a separate portal.
A load-intelligence platform routes charging and industrial loads to off-peak hours and nearby surplus solar without a multi-month integration per utility or prosumer.
The distribution utility gets demand-response participation and peak shaving without new transformer capex.
Where to start
Stand up a sandbox Network Adapter for one feeder. Register two prosumers and one flexible load, publish a signed surplus-kWh catalogue, and run a simulated noon-hour matching-and-settlement loop under a simple feeder-limit policy. Production is the same code with the utility's real endpoints and policy pack.
