How many home batteries has Australian Capital Territory installed?

The Clean Energy Regulator's small-scale installation postcode data, which counts every battery that has claimed small-scale technology certificates since July 2025. August 2026 is provisional: installers have up to twelve months to claim, so the latest month always rises later.

Batteries installed since July 2025 for every 1,000 houses in the 2021 Census: separate houses, semi-detached homes and townhouses, not flats, which rarely get a battery. New suburbs have grown since 2021, so their figure runs high. Postcodes with fewer than 500 houses show no figure and aren't ranked.

The Cheaper Home Batteries Program pays small-scale technology certificates (STCs). A battery gets 6.8 certificates per kWh of usable capacity for the first 14 kWh, 60% of that from 14 to 28 kWh, and 15% from 28 to 50 kWh. The factor drops to 5.7 on 1 January 2027, so the same battery gets less after that date. The date on the battery's electrical safety certificate decides which factor applies, not the date you sign a contract. Your installer claims the certificates and takes their value off the price. The government clearing house pays $40 per certificate before GST, which is why each figure says "up to": certificates also trade on a market, usually for less. Rules checked 28 September 2026.

Western Australia pays Synergy customers $130 per kWh of usable capacity up to $1,300, and Horizon Power customers $380 per kWh up to $3,800, if the battery joins an eligible virtual power plant. New South Wales pays certificates for joining a virtual power plant, which your VPP provider buys at its own price, so no dollar figure is shown. South Australia has a virtual power plant offer for concession holders whose amounts we could not confirm from an official source, so it is not shown. Victoria, Queensland, Tasmania, the ACT and the Northern Territory have no household battery rebate open.

Every retailer publishes its current household electricity plans through the Consumer Data Right, hosted by the Australian Energy Regulator. Rates include GST where GST applies. Feed-in is the highest rate the plan pays for exported power; time-of-use shows the peak and off-peak usage rates. Check the plan's full terms with the retailer before switching.
