NESC / PDRS Calculator NSW

Estimate Peak Reduction Certificates (PRCs) under the NSW Peak Demand Reduction Scheme — the certificate stream often quoted loosely as “NESC” rebates.

Annual PRC value
$550
Certificates / year
500
Solar panels alone do not earn PRCs — midday generation does not reduce the evening peak. A battery that discharges into the 2:30–8:30 pm peak window is what creates PRC value. The panels themselves earn federal STCs — try the STC calculator.

Estimate only. Actual PRC volumes depend on IPART calculation methods and firmness factors; certificate prices fluctuate.

How PRCs are calculated

Under the NSW Peak Demand Reduction Scheme (part of the Energy Security Safeguard, regulated by IPART), one PRC recognises 0.1 kW of capacity reliably removed from the summer peak window — so each kW of peak demand reduction creates 10 PRCs per peak season year. Value is the certificate count × the PRC market price, and it reaches you as a discount through an Accredited Certificate Provider (ACP).

Frequently asked questions

What is the NESC?
There is no NSW scheme literally called the NESC — the label is used loosely for the NSW Energy Security Safeguard schemes: the Energy Savings Scheme (ESCs) and the Peak Demand Reduction Scheme (PRCs), both regulated by IPART.
Does solar earn PRCs?
Not on its own — midday generation does not reduce the evening peak. A battery that discharges into the 2:30–8:30 pm summer peak window is what earns PRCs; the panels themselves earn federal STCs.
How are PRCs calculated?
One PRC recognises 0.1 kW of peak demand reduction capacity, so each kW reliably removed from the peak creates 10 PRCs per peak season year. Exact volumes depend on IPART methods and firmness factors.
How much is a PRC worth?
PRC prices float with the certificate market; the calculator defaults to $1.10 — adjust it under Advanced. Value reaches you as an installation discount through an Accredited Certificate Provider.
