ElectraNet Pty Ltd, the South Australian transmission network operator, and the Australian Energy Market Operator (AEMO) today announce their intention to conduct a joint feasibility study of transmission development options that could economically increase the interconnector transfer capability between South Australia and other National Electricity Market (NEM) load centres.

The study is important in light of South Australia’s extensive renewable energy resources and their ongoing development potential. The extent to which these resources can be leveraged to meet the challenges of climate change and a low carbon intensity future may be limited by the existing ability to export energy from South Australia.

ElectraNet CEO, Mr. Ian Stirling, said “While the existing network has the capacity for additional generation developments, the purpose of the feasibility study is to investigate the technical and economic merit of transmission development options that would allow more extensive development of South Australia’s renewable and other energy resources”.

AEMO CEO, Mr. Matt Zema, said “A number of options to enhance transmission capability will be considered, ranging from incremental upgrades to existing interconnectors to major new high capacity interconnectors between South Australia and the eastern states”.

The study will involve developing a range of feasible and cost effective transmission development options, determining reasonable cost estimates for each of the options proposed, developing reasonable market development scenarios that can be used to assess the economic merit of the options and using simulation techniques to assess the market benefits generated by each option.

On conclusion of the feasibility study, ElectraNet and AEMO will publish a joint public report on the technical and economic feasibility of the options considered.

The feasibility study is planned for completion by mid 2010.

ElectraNet and AEMO welcome engagement with market participants and other interested stakeholders in relation to the study.
