Required consumer data and closed accounts in the energy sector

For a closed account in the energy sector, billing data held by a retailer and metering data held by AEMO is required consumer data unless it “relates to a transaction or event that occurred more than 2 years before” a particular point in time while the account is closed. For example, this point in time could be when a consumer data request is made while an account is closed. That is, for closed accounts, retailers will not be required to share billing data, and AEMO will not be required to share metering data, where the data relates to a transaction or event that occurred more than 2 years before the date a consumer data request is made.

Any other form of consumer data in relation to closed accounts is voluntary consumer data.

See clause 3.2(7) of schedule 4 for more information in relation to required consumer data on closed accounts, and clause 3.2(3) in relation to voluntary consumer data.

However, please note that the CDR Rules only require a retailer data holder to share CDR data that relates to a closed account if the CDR consumer remains an eligible CDR consumer in relation to that data holder (see Rule 1.10B and Schedule 4, clause 2.1 for the definition of an eligible CDR consumer in the energy sector).

For example:

• Tom is eligible in relation to retailer ABC and his previous energy account with retailer ABC closed on 1 January 2024
• an ADR makes a consumer data request on behalf of Tom in relation to his previous energy account on 1 January 2025 and at this point in time:
  • billing data held by retailer ABC and metering data held by AEMO in relation to Tom’s previous account will be required consumer data unless it relates to a transaction or event that occurred before 1 January 2023
  • any other form of CDR data will be voluntary consumer data, including billing / metering data that relates to a transaction or event that occurred before 1 January 2023.
