Story summary

Australia installed over 500,000 home batteries, cutting wholesale power prices by 47 percent, Energy Minister Chris Bowen said.
Rebate gave a 30 percent discount and, from May 2026, shifted to tiered subsidies—full to 14 kWh, 60 percent for 14–28 kWh, and 15 percent for 28–50 kWh.
After the tier change, average battery size fell from about 40 kWh to 20–30 kWh.
AEMO chief Daniel Westerman said passive batteries boost grid stability and cut costs.

History

Historical Context

After the 2011 Fukushima accident, Japan accelerated renewable incentives, launching a feed-in tariff in November 2009 and revising it on 18 June 2012 to 42 yen/kWh, spurring solar PV growth to 50 GW by 2017. Meanwhile, the global battery market, valued at about $30 billion in 2021, is dominated by Chinese manufacturers, prompting other Asia-Pacific nations to explore similar subsidy schemes.
