What is battery storage?

A simple guide to understanding how battery energy storage systems (BESS) work and why they matter for cleaner, more reliable energy.

How battery storage works

Think of battery storage as a giant rechargeable battery for the electricity grid. It stores energy when there's plenty available and releases it when it's needed most.

What is BESS?

Battery Energy Storage Systems (BESS) are large-scale batteries that work like massive power banks for the electricity grid. They charge when electricity is abundant and cheap, and discharge when it's needed most.

Now

As Australia transitions to more renewable energy from solar and wind, we need ways to store that energy for times when the sun isn't shining or wind isn't blowing. Batteries fill that gap.

Safe

Modern battery systems include multiple layers of safety features, fire suppression systems, and continuous monitoring to ensure safe operation.

Fast

Batteries can respond in milliseconds—far faster than traditional power plants. This instant response helps keep the grid stable and prevents outages.

Why storage matters

Common questions

Are batteries safe?

Yes. Modern battery systems include multiple safety features including fire suppression, temperature monitoring, and automatic shutdowns. They're designed to international safety standards and undergo rigorous testing.

How long do batteries last?

Large-scale battery systems are designed to operate for 15+ years, with regular maintenance and monitoring to ensure optimal performance throughout their lifetime.

What happens to batteries at end of life?

Battery components can be recycled and repurposed. We're committed to responsible end-of-life management, including recycling programs and circular economy practices.

Do batteries make noise?

Battery systems produce minimal noise, typically from cooling systems. We design projects to meet strict noise regulations and minimize impact on nearby residents.
