Location of the Cockburn Transformer in Relation to the Township

GENERATION The RAES scheme supplies electricity to the township of Cockburn by purchasing electricity from the NSW grid and on selling it under the RAES tariff rates. The Principal shall continue to purchase power under existing arrangements for the RFP. No services are required for Generation in the RFP response.

11

DISTRIBUTION The 20 customers in Cockburn are supplied with electricity via a distribution line from Broken Hill owned by Essential Energy (wholly owned by Origin Energy), that in turn sources energy from the National Electricity Market (NEM). The RAES scheme purchases wholesale energy from Essential Energy at the Cockburn boundary then retails that energy within a SA Government owned reticulation system that connects to each consumer in the community. Electricity is supplied via a town mini grid system that is comprised of approximately 150 metres of low-voltage (415 V) overhead lines, supplied from a single 22kV/415V step down transformer connected to the Origin HV (22 kV) line which feeds the township from the NSW grid.

COMMUNICATIONS RAES does not currently have any local communications at Cockburn as no power generation facilities exist. FURTHER INFORMATION The following website provides additional information regarding the town of Cockburn: http://www.cockburn.org.au/
