Atmos Renewables has recently announced the financial close for the Merredin Battery Energy Storage System (BESS), a groundbreaking project set to utilize Tesla’s Megapack batteries with grid-forming inverter technology. The 100 MW / 400 MWh project, valued at $145 million USD ($220 million AUD), will be located southwest of the Merredin Solar Farm in Western Australia’s Wheatbelt region. strategically situated along the 220 kV Muja–Kalgoorlie transmission line.
The Merredin BESS is a collaborative effort between Atmos Renewables and Nomad Energy, aimed at delivering reliable and clean energy solutions tailored to the needs of Western Australians. This initiative not only supports the state’s renewable energy targets but also enhances grid resilience in the region.
Construction of the Merredin BESS is expected to commence shortly, with a target completion date in early 2027. The project is anticipated to create around 70 construction jobs and will mark Atmos’ first-ever battery facility, adding to its portfolio of 18 operational assets. Additionally, Atmos and Nomad have plans to develop a pipeline of renewable energy projects totaling over 1 GW in Western Australia by 2030.
Nigel Baker, CEO of Atmos, emphasized the importance of community involvement in the project, stating, “Atmos is dedicated to partnering with local communities and suppliers to ensure the long-term success and positive legacy for all our projects.”
The Merredin BESS is just the latest example of Tesla’s increasing influence in the global energy storage sector. Following the successful activation of the Collie Battery Stage 1 project in 2024 and the recent announcement that Tesla Megapacks will power China’s largest grid-scale battery plant, the Merredin BESS further solidifies Tesla’s position as a leader in energy storage technology.
During Q2 2025, Tesla deployed a record-breaking 9.6 GWh worth of energy storage products globally, showcasing the company’s continued growth in the sector. With Tesla Megapacks being utilized in some of the world’s most ambitious battery projects, the Merredin BESS represents another significant milestone in Tesla’s expanding energy footprint.
