Australia is seeing a boom in battery storage investments, with major new facilities planned to stabilize renewable energy use amid uncertainty over future energy policies.
Josh Brine reports for ABC News.
In short:
- Pacific Green is leading development on what will be South Australia's largest battery storage facility, projected to store up to 60& of the state's residential solar energy.
- New large-scale battery projects are also planned across Victoria and Western Australia, with construction of the Portland Energy Park expected in 2026.
- Experts warn that political shifts, especially after federal elections, could introduce risk for investors in renewable energy infrastructure.

Why this matters:
Australia's rapid push toward net-zero emissions hinges on the ability to store intermittent renewable energy. Battery systems are now emerging as a cornerstone of this transition. These massive batteries absorb excess solar and wind power during the day and release it at night or when the wind isn’t blowing. The strategy mimics efforts in California and Texas, where battery installations have started to curb reliance on fossil fuels. Unlike traditional power plants, batteries can be installed quickly and flexibly. At the same time, Australia’s power grid must keep pace with surging rooftop solar adoption and prevent blackouts or price spikes. But changes in government energy priorities can scare off private investment. If big batteries fall victim to policy swings, the grid could lose a critical bridge to a cleaner, more stable energy future.
