The Peak Demand Reduction Scheme (PDRS) has the same Scheme Participants as the Energy Savings Scheme (ESS). Introducing the PDRS means Scheme Participants have additional but similar reporting requirements.

We have aligned reporting dates for the ESS and PDRS to allow Scheme Participants to conduct combined or separate audits to suit their business needs. Dates for other processes have also been extended.

The figure below sets out the timeline for the aligned Scheme Participant process.

Scheme Participant compliance timeline

Key changes include:

  • providing AEMO data for ESS in June.
  • extending the date for submitting AESS from 30 April to 15 October.
  • extending the date for submitting individual liable demand from 30 September to 15 October.
  • extending the date for publishing the scheme liable demand from 15 November to 15 December.
  • extending the date for submitting PDRS annual statement from 15 December to 15 February.
  • changing the date for ESS shortfall penalty payments from 30 June to 31 March in the following year.

Aligning the timeframes for the ESS and PDRS will give Scheme Participants the choice to engage an auditor to undertake combined or separate audits to meet their individual business needs. We will be modifying the Detailed Scope of Works (DSW) submission form early next year so that it can be used for both schemes.

We will provide market acquisition (ESS) and market load (PDRS) data from AEMO based on 20-week revised statement data. We anticipate ESS data will be provided in June and PDRS data in August. These dates are indicative and are dependent on when data becomes available and when the last peak day occurs for the PDRS. The current estimate is based on the late peak day occurring in February. If there are delays or the last peak day occurs late in the compliance period we will adjust the timeline.

ESS and PDRS audits will be assessed by IPART after 15 October no matter when they are submitted.

We will publish updated guidance on the audit process to assist Scheme Participants and auditors in early 2023.

After the first compliance cycle is complete, we will review the process and seek feedback from Scheme Participants and auditors to make improvements.
