Name and Location
Silverton wind farm project, New South Wales, Australia.

Client
AGL Energy.

Project Description
The Silverton wind farm has the potential to be one of the largest onshore wind projects in the southern hemisphere and one of the largest in the world.

The proposed project includes:
• up to 598 wind turbines, each with three blades mounted on a tubular steel tower and a generator transformer inside or contiguous to each tower;
• electrical connections between wind turbines and the site substations, using a combination of underground cable and overhead concrete, timber or steel pole power lines;
• site substations to convert reticulation voltages of 22 kv to 66 kV to medium voltages of 66 kv to 220 kV for connection with the transmission switchyard;
• an on-site transmission switchyard that includes high-voltage transformers and switchgear for connecting the output of the wind farm to off-site transmission lines;
• a new 24 km transmission line connecting the transmission switchyard with TransGrid’s existing Broken Hill substation;
• a new 305 km transmission line connecting the transmission switchyard with SP-Ausnet’s existing Red Cliffs substation, in Victoria;
• on-site control and maintenance buildings, including storage facilities for equipment, materials and spares and a workers facilities building;
• internal access tracks, hardstand areas and other associated infrastructure required for the construction, installation and maintenance of the wind farm; and
• minor upgrades to site access through the Silverton and Eldee Station roads and the Daydream mine road.

Additional temporary construction infrastructure will also be required during the construction and refurbishment or decommissioning phases.
