Australia’s renewable energy agency, ARENA, confirmed the 100th community battery under its Community Batteries Funding Initiative and committed another AU$23.2 million (about US$15.1 million) to three new projects, according to Energy-Storage.News (September 2, 2026). These batteries sit on the electricity network, not on a single roof. They store surplus rooftop solar during the day and release it later.
Two counts, two different things
The headline “100” is easy to confuse with a bigger national number. They measure different fleets.
| ARENA’s count | Regulator’s count | |
|---|---|---|
| Figure | 100 batteries | 244 batteries |
| What it covers | Batteries under ARENA’s own program | Community battery systems connected to distribution networks nationwide |
| Who counted | ARENA | Australian Energy Regulator, confirmed in early 2026 |
According to Energy-Storage.News, network operators own 189 of the 244, across 14 networks. New South Wales and Queensland lead, with Endeavour Energy at 54 batteries, Energex at 53 and Ausgrid at 22.
What ARENA funded this time
The new money goes to three Round 2 projects, per Energy-Storage.News.
| Project | ARENA funding | Scope |
|---|---|---|
| YES Group Regional Community Batteries Project | AU$10.29 million | 14 systems across regional South Australia and New South Wales |
| Ausgrid | AU$8 million | 21 batteries across Sydney, the Central Coast, and the Hunter |
| City of Newcastle | AU$5 million | Batteries integrated with embedded solar networks |
The funding is part of the federal government’s AU$200 million Community Batteries for Household Solar measure, of which AU$171 million is allocated to ARENA.
Why It Matters to You
The article says community batteries are designed to give renters, apartment dwellers and other households without their own solar a way to share in storage benefits. They serve a whole street or substation, so in principle a household that can’t install panels or a home battery may still benefit from stored solar power. ARENA acting chief executive Chris Faris said batteries “help local communities make better use of rooftop solar” and “can help lower costs.” The article doesn’t describe subscription terms, prices or eligibility rules, and it gives no savings estimates. If you live in Australia, ask your electricity retailer or network operator whether a nearby battery offers any bill benefit.
Where it falls short
The three funding amounts add up to slightly more than the AU$23.2 million total in the article. The article also places the City of Newcastle project in regional Queensland even though Newcastle is in New South Wales, so we leave its location out. It doesn’t name the 100th battery’s location, and it gives no dates for when the 14 and 21 new systems come online. No dollar savings for households are published, and the sources don’t set out who can subscribe or how benefits reach tenants. Everything here comes from a single trade-press report; ARENA’s own release wasn’t available to us.
Quick answers
Can I subscribe to a community battery?
The sources we read don’t describe a subscription scheme. Ask your retailer or network operator.
How much will it cut my bill?
No figure has been published. ARENA says only that batteries can help lower costs.
Is ARENA’s 100 the same as 244?
No. 100 is ARENA’s program count. 244 is the regulator’s early-2026 count of community batteries connected to networks nationwide.
Why use community batteries instead of rooftop ones?
They serve a whole street or substation, so households that can’t install panels or a home battery may still benefit from stored solar power, in principle.
