The proposal can generally be described as the construction of a new high voltage transmission line with a capacity of up to 330 kilovolts (kV) originating from the existing Robertstown Substation located approximately 5 kilometres north-east of Robertstown, and travelling in an easterly direction to the New South Wales border, concluding at a location north of the River Murray near the Wentworth Road (approximately 50 kilometres north-east of Renmark). The overall development is known as Project EnergyConnect.
