The new South Australia to New South Wales high capacity electricity interconnector project is a proposed new transmission link between South Australia and the National Electricity Market (NEM).

South Australia's transmission network service provider, ElectraNet conducted a project assessment in for the proposed interconnector in July 2018. The preferred option from the project assessment would see construction of a 330 kV interconnector running from Robertstown in South Australia to Wagga Wagga in New South Wales, via Buronga.

The project would aim to improve security of electricity supply in South Australia, as well as enabling greater integration of renewables in the NEM.

The cost of the preferred project option is approximately $1.5 billion across both states. Assuming it receives all the necessary approvals, the project could be delivered between 2022 and 2024.

The next step involves the publication of a Project Assessment Conclusions Report, which is expected in November 2018. The Australian Energy Regulator (AER) will then make a final ruling on the Regulatory Investment Test for Transmission (RIT-T).

The Australian Energy Market Operator (AEMO) recommended the establishment of new transfer capacity between South Australia and New South Wales in its Integrated System Plan (ISP). The ISP provides long-term transmission system planning for the NEM and lists the new interconnector as a Group 2 priority to be implemented by the mid-2020s.

The South Australian Government first announced its support for the interconnector project in a pre-election energy policy statement released in October last year. The policy statement committed a $200 million fund for the development of the project. In August 2018, the South Australian Government announced further funding support for the project, with a $14 million package to accelerate early works on construction.
