The state’s largest wind farm is now generating at full capacity in the mid-north, marking a huge year for private investment in the local renewables sector.
Global renewable energy giant Neoen has inaugurated its Goyder South Wind Farm, which at 412 MW will be both the state’s largest, and the largest in the company’s portfolio of more than 200 energy assets across three continents.
Neoen has invested more than $2 billion in South Australia's transition to date, and its Goyder South Wind Farm has created more than 400 construction jobs and 12 permanent, long-term opportunities – as well as delivering on Neoen’s 70MW renewable energy baseload agreement with BHP.
It brings the total invested in renewable energy in South Australia to an estimated $6.4 billion and builds on a recent rush of investments across the state in solar, wind and battery storage technology.
Earlier this month, Epic Energy announced that its 200 MWh BESS (Battery Energy Storage System) at Mannum was fully operational and contributing to the state’s energy system.
Headquartered in South Australia, Epic Energy invested approximately $130 million in its battery, as part of the company’s Mannum Energy Park which comprises two solar farms with a combined 35 MW generation capacity.
In August, Potentia Energy’s grid-scale battery project at Emeroo was the first to be granted a key environmental approval under new South Australian legislation for renewable energy projects. Now its Statement of Environmental Objectives has been officially approved under the Hydrogen and Renewable Energy Act, making it the first BESS facility in South Australia to reach this stage of approvals under the new legislation.
The $400 million Emeroo Battery Energy Storage System (BESS) project, about 15 km northeast of Port Augusta, is co-located with the existing Bungala Solar Farm and includes a 225 MW system, expected to deliver up to four hours of energy storage.
Potentia is also undertaking community consultation on a proposed BESS project near Mount Gambier. With an estimated investment value of more than $220 million, construction is scheduled to commence in the second half of 2026.
