By 30 June of every year, all energy savings certificates (ESCs) representing energy savings that occurred in the previous calendar year must be registered in the Registry of Certificates in our online system TESSA. This is a statutory deadline under clause 34(3) of Schedule 4A to the Electricity Supply Act 1995 and the Scheme Administrator has no discretion to extend or waive this deadline.

This means that ESCs for energy savings activities in 2022 (2022 vintage ESCs) must be registered by 30 June 2023. You will not be able to register ESCs for energy savings activities you performed in 2022 after this deadline.

There are a number of actions required by you to ensure that you are able to meet the 30 June deadline. Early each year, you need to:

  1. Review your energy savings activities for the previous year to determine if you need to register any ESCs of the previous year’s vintage (i.e. in early 2023 you need to review your 2022 activities to determine if you need to register 2022 ESCs).
  2. Review your ESC registration limits and audit requirements, and consider whether you may need to:
    - Arrange a pre-registration audit and/or volumetric audit
    - Request changes to your condition of accreditation to increase your volumetric limit.
  3. Review the other conditions in your Accreditation Notice and the requirements of the calculation method.

We recommend you start planning your registration intentions no later than February each year. Early action will allow for audits and changes to accreditations to be completed, and manage any additional time for unexpected delays.

Preventing a rush at the end can help you lower the risk and administrative costs the 30 June deadline may otherwise create for your business.
