About the project
The Project is located approximately 4.5 km to the south-west of the township of Redhill, in the Mid North of South Australia. The wind farm will be located across the hilltops between the Snowtown Wind Farm and the Clements Gap Wind Farm.
AGL acquired Barn Hill Wind Farm Project in 2009 with development plan consent from the Port Pirie Regional Council and the Wakefield Regional Council already in place.
Due to growth in the project scope, including larger wind turbines and the potential inclusion of a battery, AGL sought new approvals through the State Government Crown Sponsorship process in 2024.
On 31 January 2025, the South Australian Minister for Planning granted Development Approval for the Project. This approval is for the wind farm, the battery, and associated infrastructure.
While the Development Approval covers the wind farm, the battery, and associated infrastructure, the battery has a different development timeline. The Final Investment Decision for the wind farm and associated infrastructure is anticipated in late 2025. The investment decision for the battery is expected to come later. This staged approach is influenced by factors such as AGL's generation portfolio needs, capital deployment, procurement processes, critical equipment lead times and connection approval timelines.
