Genus managing director David Riches stated: “Genus is pleased to be increasing its presence in the renewable market through its involvement in this flagship project, which is aimed at providing significant benefits to Western Australians.

“The award of this contract highlights the strength of our customer relationships and our reputation for reliable delivery, and the company looks forward to building on its relationship with Atmos Renewables.”

The Merredin BESS project is located 7.5km southwest of the town of Merredin, around 230km east of Perth in Western Australia’s wheatbelt area.

It is close to both the Great Eastern Highway and Bruce Rock Merredin Road, adjacent to the existing Merredin solar farm.

The project will connect to Western Power’s transmission substation at the nearby Merredin terminal station upon completion in early 2027.

In January 2025, Genus won an A$270m ($167m) contract from Western Power for the Clean Energy Link, North Region project in Western Australia.
