Arellis Energy

Small sites,
big impact.

South Australia is a world leader in rooftop solar. Arellis Energy is building the storage to match. Our batteries, each just under 5MW on about a quarter of a hectare (around 50m x 50m), are designed to connect straight into the local grid, soaking up the day's sunshine and powering homes and businesses through the evening.

One site at a time, one region at a time, we're building the backbone of a reliable, affordable, clean-energy South Australia.
