Australia’s largest wind farm is set to become even more significant for the nation’s clean energy future, with a 150 megawatt (MW)/600 megawatt-hour (MWh) battery energy storage system (BESS) to be constructed alongside Golden Plains Wind Farm in Victoria, Australia.
TagEnergy has appointed Consolidated Power Projects Australia (CPP) as Balance of Plant contractor for the standalone battery facility. This milestone positions CPP at the heart of one of the country’s most transformational renewable energy projects.
CPP will oversee the full suite of civil and electrical works required to bring the Golden Plains BESS online, including site preparation, foundations, cable routes, substation works and integration into AusNet’s Golden Plains Terminal Station. The company’s role is critical in managing the complex interfaces between the BESS, the existing Stage 1 wind farm and the broader network, by ensuring a reliable, technically robust foundation for one of the largest grid-scale storage assets in the country.
Tesla will supply 168 Megapack 2XL units for the project, forming the core of a system designed to absorb, store and release clean electricity generated by the 1,333 MW Golden Plains Wind Farm. With 756 MW of Stage 1 nearing the final stages of commissioning and Stage 2 construction well underway, the future battery will add a new layer of flexibility to a project that will ultimately deliver around 9 per cent of Victoria’s energy needs when completed in mid-2027.
Andrew Riggs, Managing Partner at TagEnergy Australia, believes pairing large-scale wind with onsite storage would strengthen Victoria’s energy security and support a more resilient grid.
“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,” he said.
“Golden Plains BESS will help balance supply and demand on the grid and provide critical capacity during peak demand periods. It will optimise the use of renewable electricity as we continue to accelerate the energy transition.”
Construction of the BESS will begin early 2026. This includes the Megapacks, a new substation and an operational facility located within the operating Stage 1 wind farm footprint. Once online, the asset will enhance the efficient use of Golden Plains’ high-volume generation, enabling more renewable energy to flow reliably into Victorian homes and businesses.
The project cements TagEnergy’s evolution into a multi-technology player in Australia. While Golden Plains is its first local BESS, the company inherits a pipeline of approved and proposed storage developments through its acquisition of ACE Power and brings deep global experience gained from delivering six operational BESS projects in the UK and building France’s largest battery system.
And for CPP, the contract underscores its growing leadership in delivering complex grid-connected renewable infrastructure and highlights the critical role homebred engineering expertise will play as the nation scales up clean energy deployment.
