Its role is to provide improved reliability and stability to the electricity network on Yorke Peninsula and South Australia.

It feeds 33 kV lines to various towns across the lower end of the peninsula and receives electricity generated by the Wattle Point Wind Farm.

It was part-funded by a grant from the Commonwealth Government through the Australian Renewable Energy Agency (ARENA).
