PPA Settlement Layer

Meter the megawatts.
Settle without invoices.

Stand up an automated settlement system where energy delivered under a long-term power purchase agreement is metered and paid for without manual invoicing. Verified meter readings feed directly into the settlement calculation, so payment at the agreed rate happens automatically each billing cycle.

The Foundation

The Execution Mechanics

Replace monthly manual reconciliation with a metered, self-settling power purchase agreement.

01.

Metered Delivery Feed

The Energy Meter Oracle streams verified delivery readings into the contract, so settlement is based on actual energy supplied rather than a reconciled estimate.

02.

Rate-Bound Calculation

The agreed tariff and escalation terms are encoded once, and each cycle's payment is computed deterministically from the metered volume.

03.

Conditional Payment Release

Escrow and Conditional Settlement releases the buyer's payment automatically once the cycle's delivery is verified, removing the invoicing and approval delay.

04.

Provenance-Anchored Readings

The Provenance Notary binds each reading to the delivery point and interval, so a disputed figure is checked against a sealed source.

05.

Cycle Reconciliation

Each billing cycle closes on-chain with a matched record of energy delivered and amount paid, eliminating the monthly spreadsheet reconciliation.

06.

Dispute-Resistant Trail

Because both generator and buyer settle against the same anchored readings, contested cycles resolve against a signed record rather than dueling invoices.

The PPA Settlement Lifecycle

Follow a single billing cycle from metered delivery through automatic calculation to settled payment.

Smart Contract Anatomy

Cerulea decomposes power purchase settlement into modular contracts. Each layer meters delivery, calculates payment, releases funds, and closes the cycle without manual invoicing.

Applicability Across the Spectrum

Automated PPA settlement is a horizontal capability. Here is how different actors under long-term agreements put the shared ledger to work.

Renewable Generators

Get paid automatically each cycle on verified delivery, improving cash flow certainty and removing the receivables friction of manual invoicing and buyer approvals.

Network & Execution Architecture

Whether you are bridging a generator's SCADA and billing systems or reading directly from revenue meters, Cerulea routes both into one settlement ledger.

Track A: Billing System Bridging

For generators and buyers on legacy billing platforms. Metered delivery is translated into signed on-chain settlement records through the API gateway.

Technical Methodology

The legacy timeline reflects energy settlement integration benchmarks. Wiring metering and billing systems, building custom tariff logic, and shipping conditional escrow for an average agreement takes a baseline of 8 months. Building the same architecture on Cerulea takes a baseline of 2 weeks, because Cerulea Studio visually translates your tariff and settlement rules into pre-audited WebAssembly binaries and provisions the settlement ledger and escrow instantly.
