Profile audits

Consumption profiling is a method of allocating electricity consumption to half-hour periods.

Consumption profile requirements

Profiling electricity allows retailers to reconcile predictable electricity use without a meter. The ability of competing retailers to develop and maintain their own profiles improves competition in the retail market.

We randomly audit profile owners. Any industry participant may request a selective audit of any other industry participant’s compliance under the Code and the application and use of any profiles. If you would like to request an audit, please contact compliance@ea.govt.nz.

What profile audits cover

Profile audits cover the:

  • documents detailing the methodology of the profile
  • application of dynamic and estimated elements of the profile
  • profile population list.

See the following guidelines.

Our role

It's our responsibility to:

  • either approve or reject new profiles
  • audit profiles used in the reconciliation process in accordance with Schedule 15.5 of the Code
  • review the structure of every approved profile at least every three years. Each review must determine whether:
    • the criteria for profile definition are still appropriate, and
    • if applicable, the existing sample be presented.
