  title: EnergyCredential
  version: '2.0'
  description: 'Base class for all DEG energy-sector Verifiable Credentials issued by electricity distribution
    utilities. EnergyCredential is a subclass of beckn:Credential that adds the common envelope properties
    shared by all DEG energy credentials: a structured issuer object (with regulatory licenseNumber),
    issuance/expiration dates, DeDi registry-based revocation status, and a W3C-style cryptographic proof.

    Concrete credential types (ConsumptionProfile, GenerationProfile, StorageProfile, ProgramEnrollment,
    UtilityCustomer) subclass EnergyCredential and add domain-specific credentialSubject properties.'
