ElectraNet has been actively exploring options to improve the reliability of supply to Port Lincoln, including options to replace or upgrade the transmission lines serving the lower Eyre Peninsula.

ElectraNet’s most recent assessment of the line condition indicates that components of the line are nearing the end of their functional life and will require replacement in the next few years.

To enable this work, ElectraNet has included in its 2018-19 to 2022-23 revenue proposal to the Australian Energy Regulator (AER) an allowance for the replacement of major transmission line components on the Eyre Peninsula.

Alternatively, the full replacement of the line (for example as a double circuit line) may be more cost effective and deliver greater benefits to Eyre Peninsula customers through potentially improving supply reliability and capturing other market benefits.

To take this forward, ElectraNet is undertaking the Regulatory Investment Test for Transmission (RIT-T), which will assess the costs and benefits of alternative network and non-network solutions.

Current status

In April 2017 five credible options to upgrade the power supply were identified in a Project Specification Consultation Report. Since then ElectraNet has undertaken a detailed options analysis in accordance with the RIT-T requirements.

Following these investigations and assistance from various project stakeholders an option that delivers the greatest net market benefits has been identified.

The option includes the construction of a new double-circuit 275 kV power line between Cultana and Yadnarie and a new 132 kV double-circuit power line between Yadnarie and Port Lincoln.

This option will provide the Eyre Peninsula with a reliable power supply and the ability to meet future electricity demands from proposed mining ventures and wind farms. If the option is approved in due course by the Australian Energy Regulator (AER), it is expected to cost approximately $300 million. Subject to receiving all necessary approvals, the option would be operational by the end of 2020.

As part of the RIT-T process, the community is invited to comment on the information and recommendations detailed in the Project Assessment Draft Report (PADR) which is available for download at https://www.electranet.com.au/projects/eyre-peninsula-electricity-supply-options/.

Responses to the PADR are due on or before 19 January 2018.

ElectraNet will then consider the feedback and complete a Project Assessment Conclusions Report by April 2018 to be delivered to the AER for consideration. A final ruling by the AER on the outcomes of the RIT-T process is expected by mid-2018.
