PDRS Virtual Power Plant connection incentive
A one-off NSW Government incentive, paid through the Peak Demand Reduction Scheme, for connecting a battery to a virtual power plant.

It is on top of the federal Cheaper Home Batteries discount and any offer the VPP makes itself. Batteries from 2 kWh up to 50 kWh are eligible from 1 July 2026, and it can be claimed once per electricity meter (NMI).

How payback works for a Ermington household
For an average NSW household with a quarterly electricity bill around $ 497, a 6.6 kW system typically saves about $2,106 per year, combining bill offset (you import less) and feed-in credits (you export excess to the grid). Out-of-pocket cost after rebates is about $ 5,476, putting payback at 2.6 years.
That payback assumes a tier-1 panel system on the Clean Energy Council's approved list (Trina, REC, JA Solar or similar) with a Sungrow or Fronius inverter. Budget gear is 15-20% cheaper but the warranty is half as long and the inverter usually needs replacing at year 8-10, so the lifetime numbers are worse.
