What rebate does a 15 kWh battery get?
Installed by 31 December 2026, a 15 kWh battery (a little over the 14 kWh mark where the rate falls) earns 99 certificates. Each one is worth up to $40, so your installer takes $3,960 off the quote. The full rate covers the first 14 kWh only; the remaining 1 kWh count at 60%.
Put in from 1 January 2027, it gets 83 certificates instead, about $3,320, since each kWh earns a little less after every half-yearly step down.
The 15 kWh rebate, state by state
The federal part is identical in every state. Two states give more. Western Australia pays $1,300 to Synergy customers or $3,800 to Horizon Power customers once they join a virtual power plant. In New South Wales, the VPP incentive comes to about $540 on top. The ACT gives no rebate but offers a 3% loan instead.
