Atmos Renewables has achieved financial close on its landmark Merredin Battery Energy Storage System (BESS), signaling the company’s first greenfield development to proceed to construction. This milestone also marks Atmos’ entry into the Western Australian market and its debut in battery storage infrastructure.
The 100 MW / 400 MWh BESS is located approximately 8 km southwest of Merredin, within the Wheatbelt region. Developed in partnership with WA-based Nomad Energy, the facility will offer four hours of dispatchable energy storage, enhancing grid stability along the Muja–Kalgoorlie 220 kV transmission corridor.
CEO Nigel Baker emphasized the project’s alignment with Western Australia’s renewable energy goals and its role in improving local energy resilience. The BESS will connect to the South West Interconnected System (SWIS) through Western Power’s Merredin Terminal Station and is expected to be the first WA project to reach construction under the Australian Government’s Capacity Investment Scheme, which supports the national 82% renewable target by 2030.
GenusPlus Group will lead construction using Tesla Megapacks equipped with advanced grid-forming inverter technology, while Western Power oversees the high-voltage grid connection.
Atmos Renewables anticipates around 70 construction jobs at peak and is committed to local and First Nations business engagement, along with regional training initiatives. A Community Benefit Fund will also be established to support local health, education, and environmental programs.
“Merredin BESS reflects our long-term dedication to communities and a low-carbon future,” Baker said. “We’re proud to invest in regional WA and foster a legacy of clean, reliable energy.”
