description: >-
  FinOps scaffold for Ameren. The Share My Usage / Green Button program is a regulator-driven data-sharing service rather than a commercial API; access is granted under the Illinois Commerce Commission framework with no documented metered billing. FOCUS mappings remain conceptual.
notes: >-
  Ameren Illinois operates the Share My Usage / Green Button Connect My Data program (operated by data custodian Aclara) under the ESPI standard. Access for authorized third parties is governed by a registration and testing process rather than a metered, priced API. Rate limits are not publicly published; the program documents a 2-4 week onboarding and 24-month rolling data window. Reconcile if Ameren or Aclara publishes specific rate-limit or pricing values.

      Placeholder meter for engagements settled outside a metered API. Real
      meters cannot be enumerated until Ameren publishes a metered
      API billing surface.

principles:
  - name: Visibility
    description: >-
      Without a public usage API, consumers must rely on contract reporting,
      invoice line items, and any tenant dashboards provided under the
      partner agreement.
  - name: Allocation
    description: >-
      Allocate spend by purchase order, contract identifier, or business unit
      receiving the Ameren service. Tag at the procurement layer, not
      the API call layer.
  - name: Optimization
    description: >-
      Optimization levers live in commercial negotiation (volume commitments,
      term length, scope) rather than in API-level caching or throttling.
  - name: Accountability
    description: >-
      Procurement and the business owner of the Ameren relationship own
      the spend; finance reviews invoice lines on the contract cadence.
