About the Big Battery

Why do we need a big battery?

Across Victoria, residential solar panels flood the grid with energy during periods of sunlight. This often leads to an excess of energy produced at off-peak times.

A big battery means that excess energy can be stored and released back into the grid as it’s needed during peak times. 

How does a big battery stabilise the grid? 

The battery will ensure that energy is released quickly during periods of high demand. This will help maintain a steady supply of energy and reduce blackouts.

How much energy will the big battery store?

The Progress Power big battery can hold enough energy to power 287,499 homes for one hour.

What technology will the big battery use and what are the risks?

The Progress Power big battery will use similar technology to regular batteries installed in homes. There are no known health risks associated with large-scale batteries that are properly installed and maintained.
