Big Batteries in Collie are not Western Australia’s only energy insurance policy

Most people haven’t heard of the Mondarra Gas Storage Facility, but it’s quietly keeping Western Australia’s energy secure.

Located 350km north of Perth, this facility stores gas underground with a capacity equivalent to 210 grid-scale batteries. To build that much battery storage would cost over $300 billion.

It plays a critical role during the market shortfalls and is essential for backing up renewables as coal generation retires.
