Overview
- Australians bought 183,000 residential batteries in the second half of 2025, about four times the prior year and equal to installations from 2020–2024 combined.
- Total installed batteries on homes and businesses now exceed 450,000, with rebates cutting typical upfront costs by roughly 30% or about $4,000.
- The federal government has added $5 billion to the original $2.3 billion battery scheme and tightened eligibility after reports of vendors selling oversized systems.
- Rooftop solar has reached about 28 gigawatts across more than 4.3 million homes, surpassing 22.5 gigawatts of coal capacity, while 2025 PV installs fell 20% to 254,664.
- AEMO is pushing retailers to expand virtual power plants to coordinate dispersed storage, as analysts link rising batteries and renewables to lower fourth‑quarter wholesale prices and note current batteries typically provide 2–4 hours of high‑output supply.
