What may be available

Support to check before the quote is accepted.

Rebate amounts and access rules are not guaranteed. The important part is making sure the quote shows each discount clearly and does not hide assumptions inside the headline price.

Federal solar and battery incentives can apply to eligible WA systems.

The WA Residential Battery Scheme offers state battery rebate support for eligible Synergy and Horizon Power customers.

No-interest loans may be available for eligible applicants under the WA scheme.

Eligibility

The customer must satisfy WA participant, property and supply-account requirements.
The battery and inverter must align with the relevant supported product lists.
The WA scheme requires VPP participation and approved vendor process rules.

Stacking

WA battery support is designed to work alongside the federal Cheaper Home Batteries Program.
The quote should separate the federal certificate value, WA rebate and any loan amount.
The approved vendor generally handles the rebate process rather than the customer claiming it manually.

Watchouts

Batteries installed before the scheme start date are not treated the same as new eligible installations.
VPP participation is a real condition, not just a hardware capability check.
Loan eligibility includes financial and household-income requirements.

WA FAQ

Does WA battery support require joining a VPP?

Yes. WA scheme eligibility includes participating in an approved Virtual Power Plant product.

Do Synergy and Horizon Power customers get the same amount?

No. The WA scheme has different maximum rebate settings by electricity service area, so the quote must match the customer account.
