OpenExtra payment for joining a VPP, scaled to battery size
- Paid for batteries of 2 to 50 kWh that join a participating VPP, from 1 July 2026.
- The amount scales with the battery capacity offered to the grid, capped at 28 kWh, and varies between VPP providers.
- Paid upfront, in instalments or as bill credit, once per electricity meter.
- Stacks with the federal discount. Apartment buildings use a separate NSW apartment battery discount instead.
- The NSW home battery installation discount closed on 1 July 2025 when the federal program started.

The federal discount, in plain English
- It comes off the installer's price. There is no form to fill in and no income test.
- Batteries of 5 to 100 kWh qualify, but only the first 50 kWh of usable capacity earns certificates, and bigger batteries earn less per kWh.
- The battery must be on the approved list, installed by an SAA-accredited installer, paired with solar, and able to join a virtual power plant. One per electricity meter.
- It is the same in every state; it does not vary by postcode.
- It steps down every six months. From 1 Jan to 30 Jun 2027 the factor drops to 5.7.

New South Wales battery rebate questions
- Is there a NSW battery rebate in 2026?
- Not as an upfront NSW discount any more: that closed on 1 July 2025. NSW households get the federal Cheaper Home Batteries discount, plus a NSW incentive for connecting the battery to a virtual power plant.
- How much is the NSW VPP battery incentive?
- The NSW Government does not set a single dollar figure. It scales with the battery capacity you make available, capped at 28 kWh, and depends on the VPP provider and certificate prices. SolarQuotes estimated up to about $1,100 in July 2026. Compare VPP offers before signing.
- How is the federal battery rebate worked out?
- Usable capacity earns certificates (STCs): the first 14 kWh at the full factor, 14 to 28 kWh at 60%, and 28 to 50 kWh at 15%. For batteries installed 1 May to 31 Dec 2026 the factor is 6.8. A 13.5 kWh battery earns 91 certificates, worth about $3,367 at $37 each. The installer applies it as a discount on the price.
- Is the battery rebate going down?
- Yes. The factor drops every six months. From 1 Jan to 30 Jun 2027 it is 5.7, down from 6.8. Battery prices are also falling, so a lower rebate does not always mean a dearer battery, but the discount itself gets smaller.
