By 1 July 2025, the WA Government will be offering 20,000 rebates for residential batteries of up to $5,000 for Synergy customers and up to $7,500 for Horizon Power customers, with the value to be determined by the size of the battery.
The battery rebate for up to 19,000 Synergy customers will be $500 per kilowatt hour (kWh) for up to 10 kWh of battery capacity. Up to 1,000 Horizon Power customers will be eligible for rebates of $750 per kWh for up to 10 kWh of battery capacity.
A similar number of no interest loans of up to $10,000 will also be made available to assist lower to middle income households to take part in the scheme.
The scheme will be rolled out in several rounds, commencing on or before 1 July 2025, and will be administered by a third-party service provider with appropriate capability and expertise in the delivery of similar schemes.
