Atmos Renewables has reached financial close on the Merredin Battery Energy Storage System (BESS), marking a major milestone as its first greenfield development to enter construction. Once completed, the 100MW/400MWh facility will be Atmos’ 18th operational asset, its first in Western Australia, and its debut battery storage project.
Situated about 8km southwest of Merredin in WA’s Wheatbelt region, the BESS is co-developed with local partner Nomad Energy. It will deliver four hours of dispatchable energy storage and is strategically located along the 220kV Muja–Kalgoorlie transmission line, enhancing grid stability for the Wheatbelt and Eastern Goldfields.
“The Merredin BESS exemplifies our commitment to delivering reliable, clean energy solutions tailored to the needs of Western Australians,” said Nigel Baker, CEO of Atmos Renewables. “This project not only supports the state’s renewable energy targets but also strengthens the resilience of the local energy infrastructure.”
The project will connect to the South West Interconnected System (SWIS) via Western Power’s Merredin Terminal Station. It’s also the first WA project to reach construction under the Australian Government’s Capacity Investment Scheme, which aims to achieve 82% renewable energy by 2030.
GenusPlus Group will lead construction, using Tesla’s Megapack 2XL battery and inverter systems. Western Power will oversee high-voltage connection works. Construction is set to begin soon, creating around 70 jobs at peak, with a strong focus on engaging local businesses, First Nations suppliers, and regional training providers.
