Peak Shifting
Peak Demand Shifting: Store and Shift Capacity method
The PDRS Rule sets out calculation methods for determining the number of peak reduction certificates that can be created from eligible activities.
The PDRS has 3 calculation methods for calculating peak demand reduction:
- Peak Demand Savings
- Peak Demand Shifting
- Peak Demand Response.
Each currently has 1 sub-method.
The Store and Shift Capacity (SASC) sub-method of the Peak Demand Shifting Method encourages households and small businesses to create the capacity to shift electricity demand away from peak periods.
Read below for more information about:
- activities under this method
- activity requirements
- requirements for equipment you can use
- fact sheets you need to give your customers.
Eligible activities
The PDRS Rule includes one Activity Definition under the SASC Method: BESS1 - Install a new behind the meter battery energy storage system. This activity is suspended from 1 July 2025. See our Quick Reference Guide – June 2025 for more information.
Certificates can only be created for BESS1 implementations where the battery installation date is on or after 1 November 2024 and before 1 July 2025.
Activity requirements
Batteries installed under Activity Definition BESS1 must meet requirements in the PDRS Rule.
SASC-specific requirements are set out in clause 8 and Schedule C of the PDRS Rule.
If you are an ACP, refer to the PDRS Method Guide to understand battery activity requirements under the PDRS Rule.
Equipment requirements
Activity Requirements for BESS1 in the PDRS Rule require that the batteries:
- are those on the Clean Energy Council’s list of approved batteries
- meet additional warranty and connection requirements set out in the PDRS Rule
- have a combined capacity that is greater than 2 kWh and less than 28 kWh
- are installed by an installer with Grid-Connected Battery Storage ‘Design and Install’ or ‘Install only’ accreditation by Solar Accreditation Australia.
Multiple batteries installed together as a system can be considered a ‘battery energy storage system.’
Inverters must also meet warranty requirements set out in the PDRS Rule.
For installations of multiple batteries, the consumer must pay the minimum co-payment amount once for each electricity meter, not once for each battery.
Fact sheet requirements
ACPs or their representatives must give a BESS1 fact sheet to the customer with the quotation for the installation of a battery.
ACPs must keep records as evidence of providing the fact sheet. Auditors will check the fact sheets have been provided during audit.
