Tesla has secured a $170 million order to supply 168 Megapack units for a 150 MW/600 MWh battery energy storage system at TagEnergy's Golden Plains Wind Farm in Victoria, Australia. The project will pair the southern hemisphere's largest wind farm with onsite storage to enhance grid reliability. Construction is set to begin early next year, with completion expected in mid-2027.
TagEnergy, a global clean energy developer, announced the battery project alongside its 1,333 MW Golden Plains Wind Farm, which will supply nearly 10% of Victoria's electricity needs upon completion. The wind farm's Stage 1 (756 MW) is undergoing final commissioning, while Stage 2 (577 MW) construction is underway.
The battery energy storage system (BESS) will optimize renewable energy output by storing excess power during high generation periods and discharging during peak demand. TagEnergy confirmed supplier contracts with Consolidated Power Projects (CPP) for construction and Tesla for the Megapacks. As stated in TagEnergy's announcement: “What’s better than building Australia’s largest wind farm (and the southern hemisphere’s biggest) to drive the energy transition? Adding a large-scale battery energy storage system on-site to optimise the massive amounts of clean energy being created! That’s what we’re doing at Golden Plains.”
Andrew Riggs, TagEnergy Managing Partner for Australia, emphasized the project's role in the energy transition: “The addition of large scale energy storage at Golden Plains is another vital step towards achieving a more secure and flexible supply of clean electricity for the people of Victoria. The Golden Plains BESS will help balance supply and demand on the grid and provide critical capacity during peak demand periods.”
Wallie van Hoving, President of CPP Australia, added: “We are delighted to work with TagEnergy on this project. Following our involvement in constructing Golden Plains wind farm Stages 1 and 2, this new battery storage facility presents another opportunity for CPP to support TagEnergy’s vision.”
Josef Tadich, Tesla’s APAC Regional Director, noted: “This 150 MW, four-hour Tesla Megapack system will operate as a grid-forming battery in a critical part of Victoria’s 500 kV transmission network... It will also maximise renewable generation through energy arbitrage.”
The BESS will connect to AusNet’s Golden Plains terminal station off Bells Road in Rokewood. This marks TagEnergy's first Australian BESS, building on its international experience with six UK facilities and one in France. Tesla's Megapack, designed for grid-scale storage, supports integration of intermittent renewables like wind.
