Our Renewable Energy Future — Today
Energy Storage Industries (ESI) is an Australian company built to accelerate the nation’s transition to clean, reliable energy. Founded in Queensland, ESI designs and delivers advanced battery energy storage systems engineered for performance, safety, and sustainability — helping utilities, developers, and communities unlock the full potential of renewable power.
We believe energy storage should be as dependable as the grid it supports. That’s why every ESI system is designed, tested, and supported locally to perform in Australia’s harshest conditions — from coastal regions to the remote outback. Our technology enables greater grid stability, supports the growth of renewable generation, and provides secure, flexible energy wherever it’s needed most.
Our Mission
To build a trusted, Australian-led energy storage company that empowers the transition to a clean, stable, and sustainable energy future.
