EP backup options could work best

SOME of the cheaper solutions to improve the reliability and quality of the regions power supply could deliver the greatest benefits to customers.

The Essential Services Commission considered proposals by ElectraNet and SA Power Networks in its inquiry into the quality of electricity supply on the Eyre Peninsula.

In its draft report the commission said SA Power Networks’ generation options could deliver reliability benefits that exceeded implementation costs.

For example the SA Power Networks’ option to upgrade its sub-transmission network so the Port Lincoln power station could supply the far west coast was costed at $398,700 per year.

SA Power Networks other options include installing generation at the Wudinna sub-station and upgrading the 66 kilovolt sub-transmission network; and installing generation at Wudinna, Ceduna and Streaky Bay sub-stations and upgrading 66kV sub-transmission network as required.

“The generation options, which would back up the transmission network, appear to deliver the greatest reliability benefits,” the report said. 

The commission will consult on its draft report until August 18.
