To be a successful Scheme Participant under the ESS you must complete and lodge an energy savings statement with us each year. You may also be required to have your energy savings statement audited.

We have aligned the timeline for Scheme Participant reporting under the ESS and Peak Demand Reduction Scheme (PDRS) so Scheme Participants can choose to conduct their ESS and PDRS audits together or separately to suit their business needs. Dates for other processes have also been extended. See our Scheme Participant compliance timeline page for more details.

The process for lodging an energy statement is being reviewed due to new compliance functionality being built in TESSA to bring Scheme Participant processes online.

We expect to update this page and our guidance material mid 2023 when these process improvements are finalised.

Additional information is on our TESSA for Scheme Participants webpage.

Completing your energy savings statement

We provide you with market acquisition data which is a key input to your energy savings statement. In addition, you will also need to provide data for

  • acquisitions from persons other than the market operator

  • exemptions

  • supply of electricity under Clause 10(2) of the Act

Audit inputs to your energy savings statement

If you have liable acquisitions, you must have the inputs to your energy savings statement audited unless you meet specific exemption criteria. The Compliance Guide – Scheme Participants lists audit exemption criteria.

If an audit is required, you must engage an auditor from the Audit Services Panel. The audit process requires that you complete the Scheme Participant section of the Audit Deed Poll.

The auditor must submit a completed DSW submission Form – AESS and Audit Deed Poll to IPART for approval prior to commencing the audit, which are available at Auditing Scheme ParticipantsWe will publish an updated DSW submission form on our website in mid 2023 that will allow the same DSW to be used to commence ESS and PDRS audits.

You must lodge the audit report with your energy savings statement by 16 November 2023 for the 2022 compliance period.

The Scheme Regulator assesses compliance

The Scheme Regulator will issue a Notice of Assessment (NoA) in March-April (i.e. 15-16 months after the end of the compliance period) assessing your compliance. If you have a liability for an energy savings shortfall penalty an invoice will be issued with the NoA. The shortfall penalty for the 2022 compliance period is payable by 2 May 2024. These dates have been delayed from the previous ESS process to align with PDRS compliance dates.
