You might know us as Western Australia's largest electricity generator and energy retailer, supporting 1.2 million customers across the state.

But what you might not know, is that we’re investing in renewable energy projects, including wind farms and big batteries, to help build a more sustainable and reliable future.

Our Big Battery is now live in Kwinana, we’re expanding the Warradarge Wind Farm, the WA EV Network has launched, and we have many other projects in the works.

We're a purpose-driven organisation, owned by the people of WA. Our commitment is to ensure all Western Australians have access to secure, reliable, and sustainable energy.

We believe that the benefits of renewable energy aren’t just for some, they're for everyone.

This is where you come in.
