Olympic Dam’s electricity requirements are currently met by two transmission lines – a 275 kV line from Davenport at Port Augusta which meets existing demand and a 132 kV line from Pimba which is used for stand-by purposes.
The proposed construction and operation of the new open pit mine and metallurgical plant would result in a significant increase in energy consumption, particularly electricity and diesel. The major contributors to this would be the addition of haul trucks and other heavy vehicles, electric shovels and additional primary crushers to extract and process about six times more ore than the current operation.
