Peak Demand Reduction Scheme

Why peak demand, not total energy

NSW’s grid faces its most severe stress during peak demand events - typically hot summer afternoons when air conditioning load across Sydney and surrounding areas surges simultaneously. At these moments, the cost of supplying an additional kilowatt of peak demand is orders of magnitude higher than the average cost of electricity.

The PDRS targets this specifically. Rather than incentivising total energy reduction (as Victoria’s VEU does), it creates certificates (Peak Reduction Certificates, or PRCs) based on the estimated reduction in demand during defined peak periods. A home battery that discharges during the 4–8 pm summer peak has a different, and higher, value under PDRS than a battery that discharges in off-peak hours.

What’s eligible

The PDRS covers several product categories:

Home batteries - the flagship PDRS application. Battery systems meeting the technical requirements and installed by an accredited provider are eligible to generate PRCs. The rebate has been reported in the $1,000–$2,500 range for residential batteries depending on capacity and current PRC prices.

Demand response systems - devices that can reduce load automatically in response to peak signals (smart air conditioning controllers, water heater timers).

Some appliances - high-efficiency air conditioners and pool pumps that reduce peak demand may also qualify.

How the rebate reaches you

Like the STC and VEU schemes, PDRS certificates are created by accredited providers and sold into the certificate market. The discount is applied upfront by the installer - you pay the post-discount price and the installer retains the certificate value. No separate application is required if using an accredited provider.

Stacking with other rebates

NSW households can often combine PDRS with federal STCs (for solar) and with the NSW Empowering Homes loan program (interest-free loans for solar and battery). These schemes target different costs and are not generally exclusive. Confirm current stacking rules with your installer and the relevant scheme administrators - rules change as programs are updated.
