A hyperscale operator spends 30–50% of operating cost on electricity, and the cheapest electron at any given hour is rarely from the same supplier. Yet procurement is locked into long-dated bilateral contracts, because spot-market access is fragmented, onboarding a new supplier is slow, and verifying a carbon-intensity claim means chasing self-reported PDFs. An NFH fabric-aligned procurement stack lets the operator — or an autonomous agent acting for it — treat energy as a **continuous, signed, verifiable spot market**. Suppliers publish kWh offers; the operator [discovers](/product-documentation/products/discovr.md) and contracts hourly against policy; payment [settles](https://docs.finternetlab.io/) atomically against metered delivery; and every kWh is [anchored](/product-documentation/products/observability-audit.md) for downstream carbon reporting. ## What changes * **Procurement moves from a quarterly contracting cycle to a continuous spot motion** — the operator buys the cheapest compliant electron each hour. * **Carbon-intensity claims are signed and replayable**, not self-reported PDFs — so sustainability reporting is provable, not asserted. * **Suppliers below the threshold for traditional broker access reach demand directly** — widening the supply pool and sharpening price competition. * **Variable-renewable supply finds price signal at the granularity it actually has** — solar and wind get matched to load hour by hour. * **An agent can run the loop** — discovery, contracting, and settlement happen under explicit spend and carbon policy, with a full audit trail. ## Where to start Set up a sandbox Network Adapter, publish a single-supplier test catalogue, and run a simulated hourly procurement loop against it under a simple price-and-carbon policy. Migration to production is the same code with production endpoints — so validate the policy and the carbon-credential schema first. --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.nfh.global/use-cases/cheapest-kilowatt.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
