Home battery uptake in Australia by postcode

Homerise analysis of Clean Energy Regulator data to 30 September 2026 · Method reviewed by Joern Haake · Published 2 November 2026 · Rebate figures verified 22 October 2026

The short answer

Australians installed 546,789 home batteries between July 2025, when the federal battery rebate began, and 30 September 2026: 15,288 MWh of usable storage, 28.0 kWh on average, and 12.0 batteries for every 100 solar systems ever installed. The busiest month was Apr 2026, with 87,128 installed ahead of the 1 May 2026 rebate cut. The next cut is on 1 January 2027.

How many batteries are in your postcode?

Every postcode in Australia, from the same Clean Energy Regulator data. Recent months are still filling in, so the latest figures will rise.

What the data shows

  1. The April rush. 87,128 batteries were installed in Apr 2026, 2.1 times the January to March average (41,586 a month). April alone is 16% of every battery installed since the program began.
  2. Then it fell away. 23,679 were installed in May, the lowest full month since the program began.
  3. Batteries shrank by 40% overnight. The average battery installed in April held 36.8 kWh usable; in May, 21.9 kWh. From 1 May the rebate rate fell from 8.4 to 6.8 certificates per kWh, and capacity above 14 kWh earns a reduced share, so oversized batteries stopped paying.
  4. NSW leads, QLD trails. NSW has 15.6 batteries per 100 solar systems; QLD has 9.0, the lowest of the five mainland states. The highest uptake of any sizeable postcode is Epping, North Epping (2121): 30.6 batteries for every 100 solar systems.
  5. The next cut. On 1 January 2027 the rate falls to 5.7 certificates per kWh. A 10 kWh battery's rebate drops from about $2,516 to about $2,109 (at about $37 a certificate after fees). The rebate is set by the day the battery is installed, not the day you sign.

“Every step-down so far has pulled installations forward, and the next one is 1 January. The rebate is set by the day the battery is installed, not the day you sign, so anyone weighing up a battery this year should book the installation, not just the quote, before Christmas. And buy for your evenings, not for the rebate: in April a lot of people bought far more battery than they needed.”

Batteries installed each month

The two lighter bars are still filling in: installers have up to 12 months to create the certificates.

Method

  • Batteries: the Clean Energy Regulator's small-scale installation postcode data, battery installations and usable capacity by month of installation, to 30 September 2026. The series starts in July 2025, when home batteries joined the Small-scale Renewable Energy Scheme (the Cheaper Home Batteries Program).
  • Batteries per 100 solar systems: batteries installed since July 2025 divided by all small-scale solar systems installed in the postcode since 2001. Some homes have more than one system and some systems are on businesses, so this measures uptake, not the share of homes with a battery.
  • Recent months are incomplete: certificates can be created up to 12 months after installation, so August and September 2026 will rise.
  • Rebate figures: our rules table, checked against the Department of Climate Change, Energy, the Environment and Water, last verified 22 October 2026, at about $37 a certificate after fees. The certificate price moves with the market.
  • Area names are each postcode's main suburbs; a postcode often covers more.
