The Peak Demand Reduction Scheme Rule (PDRS Rule) commenced on 29 September 2022 and 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.

The Reducing Demand Using Efficiency method is the only calculation method currently in the Rule. It relates to activities that generate capacity by saving energy during peak times. The Activity Definitions in the PDRS Rule closely relate to Activity Definitions in the Energy Savings Scheme.

Other methods will be introduced in future versions of the PDRS Rule. Further details are available on our Calculation methods and Reducing Demand Using Efficiency Method pages.

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

PDRS Rule update – February 2023

The PDRS Rule was updated on 17 February 2023. The following changes have taken effect:

  • eligible air conditioners (HVAC2), water heaters (WH1), refrigerated cabinets (RF2) and motors (SYS1) implemented from 1 April 2022 in small businesses can now be used to create Peak Reduction Certificates
  • the efficient motors activity (SYS1) now includes replacement as well as new ventilation or refrigeration motor installations implemented from 1 April 2022
  • air conditioners (HVAC2) without a Commercial TCSPF_mixed value in the GEMS Registry are required to have an Annual Energy Efficiency Ratio (AEER) in the GEMS Registry to satisfy equipment requirements.

See the Reducing Demand Using Efficiency Method page for more information about activities.
