title: EnergyTradeDelivery
description: >
  Fulfillment attributes for energy trade deliveries. Attached to
  orderItemAttributes.fulfillmentAttributes to track physical transfer of energy
  including delivery status, meter readings, and energy allocation data.
  consumedEnergy = energy TO customer (imported),
  producedEnergy = energy FROM customer (exported to grid).

  This is the v0.3 schema, originally defined as a component in EnergyTrade/v0.3/attributes.yaml.
