Frequently asked questions

• What is the Western Australian Government residential battery scheme?
  The Western Australian Government has announced a residential battery scheme to assist eligible Western Australians in purchasing a home battery to save on their power bills, while supporting a clean energy future for regional WA.
  
  The battery scheme has two components; a battery rebate and the no-interest loan offer. For eligible residential Horizon Power customers, a battery rebate of up to $7,500 is available. The value of the rebate is determined by the size of the battery installed, with the rebate at $750 per kilowatt hour (kWh). The scheme also offers a no-interest loan to eligible customers, to purchase either a residential battery or a residential battery and solar package.
