The Peak Demand Reduction Scheme Rule (PDRS Rule) applies to Accredited Certificate Providers (ACPs) and their peak demand reduction activities. It provides details about:

  • nomination as the Capacity Holder
  • recognised peak activities (RPAs)
  • product acceptance requirements
  • calculation methods for determining peak reduction capacity
  • eligibility, equipment and implementation requirements
  • conversion of peak reduction capacity to Peak Reduction Certificates.

ACPs must understand and comply with the PDRS Rule.

A new PDRS Rule was published on 24 May 2024 and applies to all implementations on or after 1 August 2024 with new battery activities commencing on 1 November 2024.

The PDRS Rule that commenced on 17 February 2023 will continue to apply to all implementations before 1 August 2024.

See the PDRS Method Guide for more information about complying with the PDRS Rule.

PDRS Rule change commencing 1 August 2024

The PDRS Rule was updated on 24 May 2024. The following changes will apply to all implementations on or after 1 August 2024:

  • heat pump water heaters with a volumetric capacity less than or equal to 425L are no longer eligible (WH1)
  • introduces a capacity factor for heat pump water heaters (WH1)
  • installation of high efficiency motors and remove a spare fridge or freezer activities are no longer eligible activities (SYS1, RF1)
  • clarification that replacement refrigerated display cabinets must replace an existing product of the same type (RF2)
  • refrigerated display cabinets with four or more display sides are not eligible (RF2)
  • lifetimes reduced to 8 years from 12 years for Class 7, 8 and 11 refrigerated cabinets with more than 3.3m2 of display area (RF2)
  • installation of a new pool pump now an eligible activity (SYS2)
  • the pool pump activity includes a lower minimum star rating, changes to the equation to calculate peak demand savings capacity, changes to the adjustment factors, and a reduced lifetime of 10 years (SYS2).

The Rule change also introduced the following changes that will commence on 1 November 2024:

  • the introduction of the installation of a new battery as an activity (BESS1)
  • the introduction of the signing of a battery up to a demand response contract as an activity (BESS2)
  • the National Metering Identifier (NMI) is required as part of Implementation data.

More information about battery activities is available on our About PDRS battery activities page which will be updated as more information is available.

See the Reducing Demand Using Efficiency page and PDRS Method Guide for more information.

Our PDRS Quick Reference Guide will help you understand and prepare for the changes.
