The Reducing Demand Using Efficiency (RDUE) method under the Peak Demand Reduction Scheme Rule (PDRS Rule) offers incentives for projects that reduce peak demand by being more energy efficient. The RDUE method has 5 activities that correspond to activities under the Energy Savings Scheme (ESS) Home Energy Efficiency Retrofits (HEER) and Installing High Efficiency Appliances for Business (IHEAB) methods.
| End-User Equipment | PDRS Activity Definitionc | ESS Method and Activity Definition |
|---|---|---|
| Install or replace a residential air conditioner | HVAC1 | HEER D16 |
| Install or replace a commercial air conditioner | HVAC2 | IHEAB F4 |
| Replace a hot water boiler or water heater with a heat pump water heater | WH1a | IHEAB F16/HEER D17b |
| Replace a refrigerated cabinet | RF2 | IHEAB F1.2 |
| Install or replace a residential pool pump | SYS2c | HEER D5 |
a Activity Definition WH1 is suspended until further notice - see below.
b Under the PDRS Rule, PRCs cannot be generated from heat pump water heaters installed in a BCA Class 1 or 4 building. This means that implementations under the corresponding ESS Activity Definition D17 in these building types cannot be used to create PRCs.
c Activity Definitions RF1 (Remove a spare refrigerator or freezer) and SYS1 (Install or replace refrigeration and ventilation motors) that were included in previous versions of the PDRS Rule are no longer eligible activities from 1 August 2024. Installing a new pool pump under SYS2 is only an eligible activity from 1 August 2024.
Evidence requirements
Evidence requirements for this method are similar to requirements for the respective ESS method and activity definitions and are set out in the PDRS Method Guide. Accredited Certificate Providers (ACPs) are not restricted in the type of evidence they provide to support certificate creation, but it must demonstrate that you have met the various equipment, eligibility and implementation requirements as set out in the PDRS Rule.
Water heater equipment requirements
Activity Definition WH1 (Replace a hot water boiler or water heater with a heat pump water heater) has been suspended until further notice. WH1 implementations occurring after 19 December 2024 are not eligible to create Peak Reduction Certificates (see our Quick Reference Guide - PDRS Rule Change December 2024 for details).
Implementations on or before 19 December 2024 are eligible to create PRC provided they meet all relevant requirements including equipment requirements.
Refrigerated cabinet requirements
Where an existing refrigerated cabinet is replaced with a new high efficiency refrigerated cabinet, the new refrigerated cabinet should be fit for purpose and the same class or type as the refrigerated cabinet being replaced – see Notice 01/2024 for more details.
