The numbers
What the combined rebate is worth
Federal + WA, by battery size. Choose your network:
| Battery (usable) | Federal | WA (Synergy) | Total rebate |
|---|---|---|---|
| 8 kWh | $2,016 | $1,040 | $3,056 |
| 16 kWh | $3,830 | $1,300 | $5,130 |
| 24 kWh | $5,040 | $1,300 | $6,340 |
| 32 kWh | $5,796 | $1,300 | $7,096 |
| 40 kWh | $6,098 | $1,300 | $7,398 |
The WA Government's own guidance puts a typical combined rebate at around $5,000–$7,500, depending on size and network — in line with the figures above. Your exact amount is confirmed at quote and moves with the STC market price.

Indicative only. Horizon customers pay less again thanks to the larger state rebate. Final pricing and eligibility depend on your home, battery, retailer and current programs — we confirm every figure in writing before you commit.
